Antidepressants in general practice

At any point approximately 10% of women and 7% of men are estimated to be suffering from a depressive disorder. Up to 30% of people suffer from a depressive disorder at some point in their life with around 18% experiencing chronic symptoms. Long-term use of antidepressants is beneficial for those who experience recurring depression or where there has been a prolonged, severe and disabling episode. However, little is known about the long-term use of antidepressants in general-practice settings. A study of 92 patients taking antidepressants long-term from 12 GP practices in Tayside, Scotland, found that 57.6% of them did not meet the criteria for any psychiatric diagnosis. Independent clinical assessments based upon diagnoses and other clinical data indicated that 31% of the participants had no clear clinical reason for continuing to take antidepressants.

Sense of Coherence and the Holocaust

The Holocaust, the persecution of Jewish people which preceded it and the chaotic state of Europe after the war must have placed an almost-intolerable burden on those that survived it. Yet there are wide disparities in how well, or badly, people coped with these dreadful events. In 1979 Aaron Antonovsky put forward the idea of Sense of Coherence to explain some of these disparities. Sense of Coherence (SOC) is made up of: the ability to comprehend what happens around oneself, the ability to manage a given situation alone or with the help of others and the ability to find some meaning for what is happening. A study of 203 child Holocaust survivors born between 1935 and 1944 asked the participants about their experiences during the Holocaust, their current health, their levels of post-traumatic stress and their SOC. The study found that SOC was able to moderate the association between traumatic experiences during the Holocaust and post-traumatic stress. SOC acted as a protective factor, buffering the impact of traumatic Holocaust experiences on child survivors in old age. Survivors with a less coherent perspective on the meaning of their life showed a greater vulnerability for post-traumatic complaints.

CBT and depression, men and women

There is now a considerable amount of evidence that cognitive behaviour therapy (CBT) is effective in treating depression. It is as effective as antidepressants, safe, theoretically sound and produces long-term reductions in symptoms. However, little is known about the differences (if any) in the effectiveness of CBT for helping men and women. An Australian study of 251 people receiving group and individual CBT measured their depression, anxiety and quality of life before and after treatment. "Men and women demonstrated equivalent pre-treatment and post-treatment illness severity, a comparable gradient of improvement on outcomes, and attainment of clinically significant benchmarks."

Drink and drugs on Man and the mainland

The GENACIS (Gender, Alcohol and Culture: an International Study) study involves researchers from over 40 countries who have been co-operating to examine drinking patterns and alcohol-related problems among national samples of men and women. The Isle of Man joined the project in 2005 when 1,000 adults were surveyed and the results of this survey were compared to an earlier UK one of 2,027 people. In the Isle of Man sample drinking frequency was associated with having poorer physical health. In the combined Manx and UK samples 'binge' drinkers tended to have poorer mental health than other drinkers. Low income and high levels of cigarette smoking were associated with poor physical and mental health in both countries. Cannabis use was related to poor mental health. Women appeared to have better physical health than men, but there was no gender difference in relation to mental health. Once income level and education had been taken into account there were no overall differences between the Isle of Man and the U.K.

Adolescents, drink, and drugs therapy

Alcohol dependence is a common problem in adolescents with both regular and binge-drinking patterns occuring. Adults often have drug treatment, along with psychotherapy, for alcohol problems but little research has been done into drug therapy for adolescents with drink problems. An Indian study of 58 adolescents divided them into two groups. One group received disulfiram while the other group received naltrexone and the study lasted for six months. The adolescents who had a relapse lasted longer (84 days on average) before relapse when taking disulfiram, than when taking naltrexone (average 51 days). Nearly 80% of participants taking disulfiram remained abstinent compared to just over 50% of those taking naltrexone. However, those taking naltrexone had less cravings for alcohol than those taking disulfiram. The researchers concluded that more research needed to be done into the effectiveness of these drugs with larger samples of participants in a variety of settings.

Learning disability and health

The British learning disability charity Mencap has launched a new initiative aimed at improving physical health care for people with learning disabilities. The project called Getting it Right follows the publication of Mencap's report into inequalities in health care experienced by people with a learning disability 'Death by Indifference'.

MIND launches legal campaign

The mental-health charity MIND has launched a campaign called Time to Challenge which aims to help people with mental-health problems who have experienced discrimination to get their cases through the courts. The charity is looking for cases that concern points of law that, if changed, could potentially set a legal precedent and have positive implications for all mental-health service users.

Depression in Parkinson's disease

Depression affects up to half of people with Parkinson's disease. A study of 52 people with Parkinson's disease and depression compared the effects of nortriptyline (an older, tricyclic antidepressant), paroxetine (a selective serotonin reuptake inhibitor or SSRI) and a placebo. The study found that the participants who took nortriptyline were five times more likely to see an improvement in their depression as those who took paroxetine. SSRIs affect the level of serotonin in the brain, whereas tricyclic antidepressants affect the level of norepinephrine. However, tricyclic antidepressants can lead to an increased risk of overdose and death due to toxic effects on the heart and brain.

Nature and brainpower

Being in nature can improve people's memory and attention according to research carried out by psychologists from the University of Michigan. Participants in the research completed a task designed to test their memory and attention; they then went for a walk either in a park or in central Ann Arbor. After their walk the participants returned to the lab and were retested on the task. Those who had taken a walk in the park showed a greatly improved performance but those who had walked in the city showed no improvement. A second group of participants took part in a similar experiment but this time instead of going for a walk they were simply shown photographs of either an urban or a natural environment before retaking the tests. The group who were shown the nature photographs did much better on the second test than the other group. The authors suggested that this could be because urban environments provide a relatively complex and often confusing pattern of stimulation which requires effort to sort out and interpret.

Low IQ and mental-health problems

There is increasing evidence that children and adolescents who score lower on intelligence tests may be more vulnerable to mental-health problems later in life. However, much of the evidence is based on individuals whose disorders were severe enough to require admission to hospital. A study of 3,258 men whose intelligence was measured during their military service and whose mental health was assessed when they reached middle age has found that lower cognitive ability was associated with an increased risk of a number of mental-health problems

Social anxiety and alcohol problems

Social anxiety disorder is associated with high rates of alcohol problems. People with social anxiety (SA) are nearly three times as likely to develop problems with alcohol and among people seeking treatment for alcohol problems 23-39% meet the diagnostic criteria for social anxiety disorder. A study of 5,877 people by researchers at the University of Michigan found that SA was related to alcohol dependence even after allowing for a number of other factors. People with social anxiety who were also alcoholics had a higher usage of health care, other mental-health problems and greater interpersonal stress than other people with SA. For the majority of people their social anxiety came before their alcohol problems, suggesting that SA increases people's vulnerability to alcohol problems.

Antidepressants and activation syndrome

Serotonin selective reuptake inhibitors (SSRIs) are a type of antidepressant and, like any other drug, they can have side effects. One of the most worrying side effects is a cluster of symptoms sometimes referred to as activation syndrome. These symptoms can include: anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (extreme restlessness and fidgitiness) and mania. Apart from being unpleasant in itself activation syndrome has also been linked to an increased risk of suicide. A Japanese study of 729 patients who had been prescribed antidepressants found that 4.3% of them developed activation syndrome. The incidence of activation syndrome was not associated with gender or age but it was linked to a diagnosis of personality disorder which quadrupled the risk.

Depression, motherhood and body clocks

Major depression during pregnancy or shortly after birth can be a devastating illness for mothers, impair the neurocognitive and socio-emotional development of the child and increase the risk of mental and medical disorders in the offspring later in life. Many people with mood disorders have disturbed body clocks. Oestrogen and progesterone are known to affect people's body clocks and it could be that changes in the levels of these substances in and around pregnancy disrupt people's body clocks and contribute towards depression. A substance called melatonin, which is secreted at night time, plays an important role in governing people's body clocks. Researchers from the University of California, San Diego, measured melatonin levels in pregnant women and new mothers with and without major depression. They found that melatonin levels were significantly lower in pregnant women with major depression but significantly higher in new mothers with major depression.

Sleep disturbance in depression

Sleep disturbance is one of the most common problems facing older adults with nearly 60% of them reporting sleep problems at least a few nights a week. Unfortunately sleep problems are often considered to be a normal part of ageing despite the fact that sleep disturbance is linked to declines in health, increases in mortality and depression. People who have had depression before tend to be more at risk of having it in the future but little research has been done into whether lack of sleep contributes to a recurrence of depression. A U.S. study of 351 older adults compared 145 people with a history of depression to 206 people who had never had any mental illness. 16.9% of the people who had previously had depression developed it again over the course of the 2-year study compared to only one person in the group who had never had mental illness. Within the group who had previously had depression recurrence was predicted by sleep disturbance; a link that was independent of other depressive symptoms, chronic medical disease and antidepressant medication use.

Depression, anxiety and cardiovascular risk

A study of 6,576 men and women participating in the Scottish Health Survey looked into the links between emotional distress, lifestyle and cardiovascular problems. At the start of the study the participants completed a 12-question survey designed to measure their general happiness, symptoms of depression or anxiety and any sleep disturbances they might have. The participants were also assessed for risk factors for heart disease and asked about their lifestyles. Their health was monitored over a 7-year period. Researchers from University College London found a significant and direct link between increasing psychological distress and an increasing risk of cardiovascular illness and death. After age and sex were taken into account people with depression and anxiety had a 50% increased risk of heart problems. However, when the researchers took people's lifestyles into account they found that smoking and physical inactivity alone explained nearly two-thirds of the increased cardiovascular risk.

Blood pressure and cognition

A study into blood pressure and thinking in older adults has found that those people who already had high blood pressure saw a significant decrease in their reasoning ability when their blood pressure rose even higher temporarily. People whose blood pressure was normal most of the time didn't suffer a decline in their cognitive abilities when their blood pressure rose temporarily. The results of the study imply that older people might find it harder to think logically in stressful situations.

CBT for eating disorders

Eating disorders are a major cause of physical and psychosocial impairment in young women, affecting at least one in twenty between the ages of 18 and 30. Anorexia nervosa accounts for around one in ten cases of eating disorders, bulimia about a third with the remainder of cases being made up of atypical disorders which are a combination of different features of anorexia and bulimia. In 2004 a form of cognitive behaviour therapy (CBT) developed by Professor Christopher Fairburn from the University of Oxford became recognised by the National Institute for Clinical Excellence (NICE) as the leading treatment for bulimia and was recommended for use across the NHS. Now, a new study by Professor Fairburn has shown that an enhanced version of the treatment is not only more effective than the older version but can be used to treat atypical eating disorders as well. 154 people were recruited for the study which was based in Oxfordshire and Leicestershire. The researchers found that the majority of patients responded well and rapidly to the new treatment and that the changes were sustained over the following year. Approximately two-thirds of those who completed treatment made a complete and lasting response with many of the remainder showing a substantial improvement. Another trial investigating the enhanced version of the therapy is showing promising results in people with anorexia.

Rose-tinted spectacles might be real

It is something of a cliche that older people tend to see the past through rose-coloured spectacles but researchers at the University of Alberta and Duke University have found that there is some truth behind it. Younger and older participants in the study were shown standardized images that depicted either neutral or strongly-negative events. Thirty minutes later they were asked to recall them and the older participants remembered fewer negative images than the younger ones. At the same time the participants underwent brain scans. Both groups had similar levels of activity in the emotional centres of the brain but the older participants had less links between the centres and the hippocampus (which involves learning and memory) when shown the negative images. However, when they were shown the negative images the older participants had stronger connections with their dorsolateral frontal cortex, a brain region involved in higher thinking processes like controlling emotions. The older people were using thinking processes rather than feeling processes to store these emotional memories. Another study by the same group of researchers found that healthy older people were able to regulate emotion better than younger people so that they were less affected by upsetting events.

Genetics of borderline personality disorder

Borderline personality disorder (BPD) is characterized by pervasive instability in moods, interpersonal relationships, self-image and behaviour and can lead to suicidal behaviour, substance abuse and failed relationships. It is more common than schizophrenia or bipolar disorder and is estimated to affect 2% of the population. A Dutch study of 711 pairs of twins and 561 parents looked into the genetic influences on BPD and found evidence for a link with chromosome 9. Another study by the same group of researchers looked at 5,496 twins in the Netherlands, Belgium and Australia and found that 42% of variation in BPD features was due to genetic factors and 58% due to environmental ones. There were no significant differences in the extent to which men and women inherited BPD and young adults displayed more BPD features than older ones.

Don't panic, go surfing

Cognitive-behavioural therapy is a well-established treatment for panic disorder but dropout rates of 25% are common and those offered treatment only around a half might respond. As part of CBT people are often taught panic-control strategies, such as breathing exercises and relaxation but a more recent approach called 'panic surfing' encourages people to 'ride out' the wave of anxiety in an accepting manner instead of trying to control their symptoms. An Australian study of 18 participants used the 'panic surfing' technique to treat panic disorder. Significant improvements occurred over the course of the treatment and were maintained at a 1-month follow-up.

CBT for health anxiety

Hypochondriasis is an excessive preoccupation or worry about having a serious illness that persists even after a doctor has examined a patient and told them that they have nothing to worry about. It is thought to affect around 3% of the population and is often characterized by fears that minor bodily symptoms may indicate a serious illness, constant self-examination and self-diagnosis and a preoccupation with ones body. Cognitive-behavioural treatments (CBT) have been shown to be effective in treating hypochondriasis and so has CBT-based, short-term psycho-educational group treatment. A Dutch study of 140 people with health anxiety looked at how different people benefited, or failed to benefit from CBT. The study found that participants with high scores for health anxiety at the start of the study tended to continue to have high scores after treatment and at follow-up tests one and six months later. People with higher "background" levels of anxiety and who were older benefited least from CBT treatment.

New drug for cognition in schizophrenia

Most of the drugs now used to treat schizophrenia were developed more through chance than through a targeted design of any particular brain circuit or neurotransmitter. However, researchers at the University of Pittsburgh have developed a chemical that boosts the flow of a neurotransmitter called GABA, low levels of which have been implicated in some of the cognitive deficits associated with schizophrenia. A small study of 15 men, aged between 18 and 50 divided them into two groups. One group took the chemical (MK-0777) and the other group took a placebo. Over the four weeks of the study the participants took various psychological and EEG tests to measure how well their working memory was performing. Both the psychological tests and the EEGs showed that the people taking MK-0777 had improved working memory function and the drug seemed to have few side effects. However, there will still be a lot of work to do before MK-0777 is licensed for general consumption.

Low spirits and pot bellies

Having a pot belly can be associated with a number of different health complaints including cardiovascular problems and diabetes. Depression has also been linked to these conditions and a study of 2,088 adults, aged between 70 and 79 in Amsterdam, has found that depression can be linked to the development of a larger abdominal circumference. Participants in the study were screened for depression at the beginning of the research and had their overall and abdominal fat measured over a 5-year period. At the beginning of the study 4% of the participants had depression and, after adjusting for a number of other factors, this was found to be associated with an increase in abdominal fat. The researchers thought this might be because chronic stress and depression leads to the increased production of a hormone called cortisol, which promotes the accumulation of visceral (abdominal) fat. It is also possible that people with depression may have less healthy lifestyles, including a poorer diet, than other people.

Coerced medication

Laws governing involuntary psychiatric treatment exist in all EU member states and in other developed countries. Under these laws an increased risk to oneself and others provides the ethical and legal justification for detaining and treating people with mental-health problems without their consent. In the U.K. this often takes the form of coerced medication (CM) whereas in the rest of Europe seclusion and mechanical restraint are more likely to be used. Researchers from the Institute of Psychiatry and City University (both London) analysed 14 papers about CM from seven different countries, published between 1987 and 2004. They found that patients receiving CM were more likely to be in their thirties with a diagnosis of schizophrenia, bipolar disorder or another psychotic disorder and most of them had been admitted to psychiatric care on an involuntary basis. Service users experienced a range of negative feelings when they received CM including fear, embarrassment, anger and helplessness, although in retrospect many said they agreed with the practice. The studies showed a lack of detailed exploration into the events leading up to CM and a complete absence of investigation into alternatives. The authors concluded that their review highlighted a lack of clinical evidence on which to base CM and point out that the practice may discourage people from seeking help from, or engaging with, mental-health services.

The Happiness Bug

Happiness can be contagious, according to a study carried out by researchers at Harvard Medical School and the University of California, San Diego. The researchers used data from the Framingham Heart Study, a famous ongoing study into cardiovascular risk with participants in the town of Framingham, Massachusetts. Their study focused on 4,739 participants in the Framingham Heart Study who completed a range of information about their levels of happiness and their social networks. The researchers found that when someone became happy a friend, living within a mile, experienced a 25% increased chance of becoming happy themselves. Their spouse had an 8% increased chance, siblings living within a mile 14% and next-door-neighbours 34%. However, not only did that person's friends become happier, their friends' friends had a 10% chance of increase happiness and their friends' friends' friends had a 5.6% chance of increased happiness. The effects were limited by geographical distance from the original person and time, lasting about a year. People who were at the centre of social networks were happier than those at the fringes. Having a $5,000 boost to one's income, however, was only associated with a 2% increase in happiness. Sadness was not found to 'flow' through networks in the same way that happiness did.

Depression in junior doctors

A study of 481 junior doctors in Brazil has found high levels of depression among them. The researchers carrying out the study divided depression symptoms into three clusters: affective, cognitive and somatic. Affective symptoms were the students' levels of sadness, dissatisfaction, episodes of crying, irritability and social withdrawal. The cognitive symptoms were pessimism, a sense of failure or guilt, an expectation of punishment, dislike of self, suicidal ideation, indecisiveness and a change of body image. The somatic cluster were slowness, insomnia, fatigue, weight changes and loss of sexual interest. The study found a high prevalence of depressive symptoms among the medical students, particularly female students, mainly involving the somatic and affective clusters. 38% of the students had at least 10 out of a possible 63 symptoms of depression. Depression scores were higher in the early years of participants' training as they moved into the hospital environment. Having a parent who was a doctor was found to reduce the risk of depression.

Tai chi and dementia

Most of the research effort into Alzheimer's disease has tended to concentrate on drug treatment but other approaches to treating the condition can also be effective. Researchers at the University of Illinois looked at the effectiveness of an intensive 40-week programme of twice-weekly sessions of cognitive behaviour therapy and support groups, along with three sessions a week of qigong (Chinese meditation) and tai-chi. A control group was placed on a waiting list for the programme. After 20 weeks those taking part in the programme had improved balance and lower-leg strength, higher self-esteem and a slight improvement in their mental functioning. No additional benefits were seen after 40 weeks but participants were able to maintain their initial gains and the intervention proved very popular with the participants and their caregivers.

Drink, drugs and ICUs

People with drug and alcohol problems already cost the health service a significant amount of money and now researchers in Salt Lake City have found that they are more likely to end up staying in an ICU as well. The researchers carrying out the study looked at the medical records of 742 patients admitted to the intensive care unit at Salt Lake City's LDS Hospital. The study found that 19% of them had a history of drug and alcohol dependence prior to being admitted; twice the rate of the general population. The patients with drug and alcohol dependence were, on average, six years younger than the rest of the ICU patients.

Cognition, video games and silver surfers

Playing computer games has traditionally been seen as a young person's activity but an increasing number of older people are 'silver surfers' and a recent study has shown that playing video games can improve cognition in this group. Researchers from the University of Illinois studied 40 older adults in their 60s and 70s. Half of them received training in a video game called Rise of Nations where players have to make decisions on resource allocation to feed and employ people, maintain their military and expand their population in an imaginary country; the other half received no training. Before, during and after the training both groups of participants took a series of cognitive tests. The video gamers became better, and faster, at switching between tasks. Their working memory was improved and their reasoning ability was enhanced. Their short-term memory of visual cues was also better than the control group's. Those who performed better on the game also performed better on the cognitive tests. The results are significant as previous research has shown that training people on a particular task improved their ability to complete the task itself, without being transferable to other situations.

Carbs, calories and cognition

People who cut out carbohydrates as part of a diet may be reducing their brainpower as well as their waistline according to a study by researchers at Tufts University in the U.S. The study compared nine women on a low-carbohydrate, Atkins-style diet and ten women following a low-calorie diet based on advice from the American Dietetic Association. The dieters completed five testing sessions which assessed attention, long-term memory, short-term memory, visual attention and spatial memory. The low-carb dieters showed a gradual decrease in performance on the memory-related tasks compared to the low-calorie dieters. Their reaction times were slower and their visual-spatial memory worse. However, the low-carb dieters did do better than the low-calorie ones on the attention task; perhaps because fat and protein, which tend to be consumed more on these kind of diets, can improve people's attention in the short term.

Conscientiousness and life expectancy

A review of 20 studies involving more than 8,900 participants in the U.S., Canada, Germany, Norway, Japan and Sweden looked into the links between personality and life expectancy. The review found that people who scored highly on levels of conscientiousness tended to live between two and four years longer than people who had low scores for conscientiousness. The influence of contientiousness was found to be as large, or larger, than many other factors affecting longevity such as socio-economic status. Within conscientiousness the sub-factors that were particularly associated with increased life expectancy were ambition and self-discipline with responsibility and self-control being less important.

Panic disorder and heart disease

A study of 405,000 people by researchers from University College London looked into the links between panic disorder and heart problems. The study found that people who were younger than 50 when first diagnosed with panic disorder were 38% more likely to have a heart attack and 44% more likely to develop heart disease than those in the general population. People who were over 50 when first diagnosed had an 11% greater risk. However, people with panic disorder had a lower risk of dying from heart disease than the rest of the population. The researchers who wrote the study weren't sure whether the symptoms of heart disease were being misdiagnosed as panic disorder or whether panic disorder actually led to an increased risk of developing heart problems.

Antipsychotics: is it time to end the generation game?

Antipsychotic drugs have usually been divided into first- and second-generation drugs with the latter being perceived as having fewer side effects than the former. Researchers from universities in Munich and Chicago looked at 150 studies comparing the effectiveness of antipsychotic drugs, which, altogether had 21,000 participants. They found that four second-generation drugs - amisulpride, clozapine, olanzapine and risperidone - were more effective than first-generation ones but that the rest were no better. When compared with the powerful first-generation drug haloperidol the second-generation drugs had less side effects but compared to other first-generation drugs there was little difference. Haloperidol - but not other first-generation drugs - produced less weight gain than most second-generation drugs. The authors called for an end to the division of drugs into first- and second-generation and an individualized treatment of schizophrenia based on efficacy, side effects and cost.

Researchers at Indiana University School of Medicine looked into the effectiveness of drugs called cholinesterase inhibitors at treating the behavioural and psychological symptoms of dementia. The drugs work by raising the level of a neurotransmitter called acetylcholine in the brain, which assists memory, thought and judgement. The researchers reviewed the results of nine clinical trials of the drugs and found that they led to a statistically-significant reduction in behavioural and psychological symptoms such as aggression, wandering and paranoia. The drugs were found to be safe and produced no side effects in contrast to the antipsychotic drugs that are sometimes used on this group of service users.

Service users' siblings

Little is known about the impact of learning disabilities and mental illness on service users' siblings. Researchers from the University of Wisconsin-Madison studied 351 people over a 46-year period all of whom had at least one sibling with either a mental illness or a learning disability and compared them to 791 people with unaffected siblings. The researchers found that people who had siblings with mental illnesses were 63% more likely to report having a depressive episode during their lifetime. Siblings of people with learning disabilities were more likely to live in the same states as them but reported much less contact with their learning-disabled siblings and reported feeling less emotionally close to them. People with a brother with a mental illness had lower levels of psychological wellbeing than those in the comparison group but people with a sister with mental illness were not at increased risk of a mental-health problem.

Postnatal depression and sleep

All new mothers experience some sleep loss following childbirth as their oestrogen and progesterone levels plunge, and they typically spend 20% more of the day awake than average during the first six weeks after birth. It is estimated that between 6.5 and 13% of new mothers in the U.S. suffer from postnatal depression and a study of 46 women by researchers at Drexel University in the U.S. looked into the links between sleep problems and postnatal depression. The study found that the mothers suffering from postnatal depression took longer to fall asleep and slept for shorter periods. The worse the women's sleep quality the worse their depression.

Exercise and anger in children

Exercise has been shown to be effective in improving children's depression and anxiety. A study by researchers at the Medical College of Georgia School of Medicine looked at the effectiveness of a 10-15 week after-school aerobic exercise programme in reducing anger among children. The researchers found that exercise had a significant effect in reducing children's anger expression as well as helping them to lose weight.

Valproate and autism

Previous research has shown that the anti-epilepsy drug valproate can contribute to birth defects, in particular neural tube defects, and now a study by the Liverpool and Manchester Neurodevelopment Group has suggested that it could also raise the risk of children developing autism. The study, of 632 live births from 620 women, compared those taking anti-epilepsy drugs at the beginning of their pregnancy with women unaffected by epilepsy. The children were assessed for autism, or related conditions, at 1,3 and 6 years of age. Around 6.3% of the children exposed to valproate developed autistic spectrum disorders, a rate seven times higher than that in the control group. However, another anti-seizure drug called lamotrigine was not associated with an increase in the risk of autism.

Law Lords ruling on duty of care to inpatients

The Law Lords have ruled that people detained under the Mental Health Act have the same 'right to life' as those in prison. Hospitals must now be seen to take responsibility to take reasonable measures to avoid real and immediate harm to patients who have been sectioned. The ruling results from a case brought by Anna Savage against South Essex NHS Trust, concerning her mother Carol, who killed herself in July 2004 after absconding from Runwell Hospital where she was being detained. The ruling holds health authorities responsible for taking measures to properly assess and prevent the risk of suicide. The High Court had previously ruled that unless gross negligence could be established, they could not be held liable for a breach of the right to life.

Locked wards raise aggression

A leading academic has presented research suggesting that locked wards in psychiatric hospitals may actually raise levels of aggression in inpatients. Delivering the annual Eileen Skellern lecture at London South Bank University on the 2nd of December Professor Len Bowers of City University presented the results of 50,000 responses from questionnaires and interviews with staff, service users and visitors from 130 of the 500 acute psychiatric wards in England. They found that a 'locked-door' policy led to service users feeling frustrated, stigmatised and depressed. It increased the risk of physical aggression to others by 11% and self-harm by 20%. Patients in locked wards were also more likely to refuse medication.

PCOS and mental health

Polycystic ovary syndrome (PCOS) is estimated to affect between 5-10% of women of reproductive age and its symptoms include weight problems, lack of regular ovulation and/or menstruation and excessive amounts of androgenic (masculinizing) hormones. While the causes are unknown insulin resistance, diabetes and obesity are all strongly correlated with PCOS. A study of 84 women in Turkey used two common measures, the General Health Questionnaire and the Beck Depression Inventory, to compare levels of mental-health problems in women with and without PCOS. The women with PCOS had significantly higher levels of mental distress than the other women and their levels of mental distress were correlated with their Body Mass Index and their Waist-to-Hip Ratio, i.e. the heavier they were and the larger their waists the worse their mental-health was.

Self-harm after hospital

The risk of suicide in the month after psychiatric inpatient care is about 100 times greater than that of the general population. Although the high risk of suicide shortly after discharge is well documented less is known about the rates of non-fatal self-harm. A study of 75,401 people discharged from psychiatric inpatient care between April 2004 and March 2005 found that 6.5% of them were admitted at least once for self-harm in the following 12 months. The risk of self-harm was greatest in the four weeks after discharge. The strongest risk factor for self-harm after discharge was an admission for self-harm in the previous 12 months. The risk of self-harm was also higher in women, younger people, those with diagnoses of depression, personality disorder and substance abuse and those with short lengths of stay.

Suicide and mental illness

People who have already tried to kill themselves are 30-40 times more likely to commit suicide than other people. A Swedish study of 39,685 people who were admitted to hospital for attempted suicide between 1973 and 1982 looked at which mental-health problems increased the risk of these people going on to kill themselves. The study lasted until 2003 and the strongest predictor of completed suicide was schizophrenia, which increased the risk by a factor of 4.1 in men and 3.5 in women. Bipolar disorder and depression increased the risk by a factor of 3.5 in men and 2.5 in women. Increased risks were also found for anxiety disorders, alcohol misuse in women, drug misuse and personality disorders.

AMHPs get sectioning powers

The Government has opened the way to nurses being able to section people. Nurses will be allowed to become approved mental-health professionals (AMHPs) as will occupational therapists, social workers and chartered psychologists. AMHPs will have to take a postgraduate diploma learning about mental-health legislation, child and adult protection, the functions of courts and mental-health review tribunals, drug abuse and risk assessment. After qualification they will specialise in assessing a person's needs, care and treatment and will have a role in decisions to detain patients.

Exercise and mental health

Research suggests that exercise reduces anxiety, depression and negative mood and improves self-esteem and cognitive functioning as well as providing a number of physical-health benefits. However, there is little or no mention of exercise in most mental-health textbooks. Researchers from Leeds and Bristol universities looked into the experiences of 11 men with serious mental illness, aged between 24 and 43 who were involved in a variety of exercise activities. They found that exercise contributed strongly towards the participants' feelings of social support.

Helping sex offenders with learning disabilities

The Sex Offender Treatment Services Collaborative

www.sotsec.org

is a group of professionals who provide treatment for men with intellectual disabilities who are at risk of sexual offending. The group provides a forum for the discussion of treatment issues as well as training and support for clinicians who are delivering group cognitive behavioural treatments for men with intellectual disabilities who sexually abuse. One of the modules in the programme uses a four-stage model - motivation to abuse, overcoming internal and external inhibitions and overcoming victim resistance - to help offenders understand their steps to offending. An article in this month's British Journal of Learning Disabilities looks at the progress of four men going through this programme and discusses some of the issues around this work.

Risperidone: longer-acting for harder cases

A depot injection is given via a long-lasting injection and aims to promote compliance in people with particularly severe mental illness, thereby enhancing relapse prevention. Risperidone is the first second-generation antipsychotic to be available in a depot format. The effects of this form of the drug have been extensively studied in trials prior to its introduction but the kinds of people who might take it have not. A Dutch study, using dispensing data from 53 community pharmacies in the north-east of the Netherlands looked to see what kind of chronic antipsychotic users switched to long-acting Risperidone. They found that the predictors for switching from an oral to a depot form of drugs were: being a man, a previous use of depot antipsychotics, recent anticholinergic drug use, and a gap in 'antipsychotic dispensation history,' i.e. a patchy history of drug-taking. Predictors of switching to depot Risperidone from a depot first-generation antipsychotic were previous use of a depot antipsychotic and consulting a specialist. The researchers concluded that compared with oral antipsychotics service users receiving a depot injection were likely to be less compliant and to suffer from worse side effects. People receiving depot risperidone as opposed to a depot first-generation antipsychotic tended to be more severely ill. The researchers concluded that the long-lasting risperidone was being used for the most severely-ill people; something that will need to be borne in mind when assessing its effectiveness.

Incontinence and clozapine

Urinary incontinence is an embarrassing and distressing side effect of the antipsychotic drug clozapine and a Korean study followed 87 people who had taken the drug for 2 years to see if the symptoms persisted. At the start of the study 10.9% of the sample reported incontinence with 41.6% having clinically-significant lower-urinary-tract symptoms. After two years the participants' score on the International Prostate Symptom Score scale had increased (i.e. they had got worse) and so had the number of participants with lower-urinary-tract symptoms (43.7%) although the change was not statistically significant. The prevalence of lower-urinary-tract symptoms was higher in the people who had taken clozapine than in the general population of the same age.

Fathers with psychosis

One in five men with chronic mental-health problems are fathers yet despite this no research has specifically investigated fathers with psychosis. A qualitative study of 10 fathers with psychosis being treated by community mental health services in West and North London looked at some of the ways psychosis affected fatherhood. The fear of one's children inheriting psychosis was a common concern among the group but they also identified positive aspects of fatherhood including: a sense of pride in the father role, a sense of purpose to one's life, a feeling of pleasure in the creation and development of life and the motivation to change for the better.

Mental-health literacy and bulimia

Mental-health literacy can be defined as "knowledge and beliefs about mental disorders that aid their recognition, management or prevention." It is thought that poor mental-health literacy is a major factor in low or inappropriate treatment-seeking among individuals affected by mental disorders and this idea has been backed up by studies involving people with anxiety, mood and substance-use disorders. Researchers in Australia looked at mental-health literacy in 158 women who had bulimia or similar conditions. The participants believed that bulimia would be difficult to treat and that even if initial treatments were successful relapse would be likely. GPs, psychologists, counsellors and close friends were all perceived to be helpful. Lifestyle changes, including taking vitamins and minerals, were also highly regarded. However, the participants were ambivalent about psychiatrists and using medication to treat the condition. Most participants believed that bulimia was common among women in the community and many had occasionally or often thought that it 'might not be too bad' to have bulimia. Low self-esteem was thought to be the most likely cause of bulimia. The study concluded that the participants held some beliefs 'likely to be conducive to lower or inappropriate treatment seeking,' and called for poor mental-health literacy to be addressed in early-intervention programmes.

Sex differences and violence on the wards

Although there is a large body of research into what causes aggression among psychiatric inpatients there is less research into what characteristics of staff can cause, or prevent, violence. Age, skill and experience have been shown to have an impact on aggression but there have been mixed results from studies into the effects of gender. A study of a medium secure unit in the north-west of England examined this issue in two male and two female wards and found that patients were more likely to behave aggressively towards members of the same sex.

The ART of reducing aggression

Aggression replacement training (ART) aims to prevent aggression by improving people's social skills, building up their impulse and anger control and developing their moral reasoning. It was originally developed for aggressive youths but is also available in a revised format for adult offenders. A study of 197 offenders by researchers at Leicester and Liverpool universities compared violent offenders who had been allocated to the programme with a control group. Those who had taken part in the training had a 13.3% reduction in reconviction. Those offenders who failed to complete the programme were more likely to reoffend than similar people who had never been on it or who had completed the course.

Sudden improvements, lasting gains

People going through psychotherapy often demonstrate sudden, dramatic improvements suggesting that they have had some kind of epiphany that has dramatically altered their outlook on life and way of thinking. These sudden changes represent genuine improvement in people's condition and those who show sudden improvements from one session to the next are more likely to show a greater and longer-lasting improvement after the end of therapy. A team of researchers at the University of Virginia in the U.S. looked into sudden improvement in 30 people going through a 12-week course of cognitive behaviour therapy (CBT) for panic disorder. 43% of the clients showed at least one dramatic burst of improvement during the course of therapy. Half of those who had had a dramatic improvement had had it between the first and second sessions, while the other half had experienced it later on. However, only the later improvers had better symptoms at the end of the study compared to people who had shown no dramatic improvement. The later improvers showed a greater improvement in their fear of anxiety-related symptoms at the end of their course of therapy, and at a six-month follow-up.

Depression and heart problems

Depression has long been recognised as a risk factor for cardiovascular problems in healthy people and for a worse prognosis in people with existing cardiovascular problems. A study by researchers at the VA Medical Center [sic] in San Francisco followed 1,017 outpatients with stable coronary heart disease for between 4-5 years. It measured their depression symptoms, levels of illness and behaviour over the course of the study. The researchers found that patients with depression had a 10% risk of a subsequent cardiovascular 'event' compared to only a 6.7% risk among those without depression. However, once the researchers adjusted for health behaviours (diet, smoking etc) and physical activity there was no longer a link between depression and subsequent heart problems. The researchers calculated that physical inactivity was associated with a 44% greater rate of cardiovascular 'events.'

Hearing deficits in autistic children

People with autism or Asperger's syndrome could hear 'slower' than other people, according to researchers in the department of radiology at the Children's Hospital of Philadelphia. The researchers exposed children to beeps, tones in pairs and vowels and sentences at different speeds, tones and frequencies. They used a technique called magnetoencephalography to measure the magnetic fields associated with brain activity and found that this occured a fraction of a second slower in autistic/Asperger's children.

'Count me in' shows lack of progress

The Healthcare Commission's annual census of mental-health inpatients - 'Count Me In' - has painted a gloomy picture of a lack of progress on mixed-sex wards and racial equality. The census found that 68% of inpatients are still being housed on mixed-sex wards; no improvement on last year. Women (78%) were more likely than men (61%) to be treated in a mixed-sex ward. People from Black and minority-ethnic groups were three times more likely to be detained than average, and up to 65% more likely to be secluded. After three years of censuses there has been no sign of movement towards improving racial inequalities in mental-health care.

ADHD and self-esteem

Attention Deficit Hyperactivity Disorder (ADHD) is estimated to affect between 3 and 7% of school-aged children. It can affect children's home, school and community life leading to poor peer relations, aggression and learning problems, which, in turn, can lead to academic failure and an increased risk of depression. However, there has been conflicting evidence about the relationship between ADHD symptoms and low self-esteem. A Swedish study of 1,714 children, which followed them between the ages of 8 and 13 measured their ADHD symptoms and self-esteem when they were eight and again when they were thirteen. The children with high levels of ADHD symptoms had lower scores in the aspects of self-esteem relating to "skills and talents" and "psychological well-being."

Parental warmth and child psychology

Parents' psychological warmth has been consistently identified as being significantly related to psychological adjustment in children and adolescents. Regardless of culture, ethnicity or geographical location about a quarter of the variation in youths' psychological adjustment is accounted for by parents' perceived warmth. However, little research into this has been done among the U.S.'s Korean community despite the fact that this commmunity has trebled in number in the last twenty years. A study of 103 Korena Americans aged between the ages of 11 and 14 has found that low perceived maternal and paternal warmth did lead to a decline in the children's overall psychological adjustment. Low maternal warmth was particularly related to the children's poor psychological adjustment.

Giving up grass: why US teenagers *don't* take dope

There has been a lot of research into why people start using cannabis and the consequences of their doing so but much less research into why people stop using the drug, or never start using it in the first place. A study of 82,106 U.S. high-school seniors found that: 50% of those reporting cannabis use in the last year felt that they should either stop completely or cut down. Among those saying that they would not use cannabis in the coming year the most frequently reported reasons were concerns about psychological and physical damage and not wanting to get high. The least frequently reported reasons were expense, concerns about having a bad trip and availability. Girls were more likely to focus on moral and behavioural concerns about cannabis whereas boys were more likely to focus on practical concerns such as the risk of arrest, loss of energy and ambition, expense and availability. Black and Hispanic students were significantly less likely than whites to note concerns about expense, personal beliefs or getting in with the wrong crowd but were more concerned about addiction.

Gateway holds good in New Zealand

The gateway hypothesis holds that drug users start off with alcohol and tobacco, move on to cannabis and then on to other illegal drugs. People who depart from this sequence of drug use are thought to be at an increased risk of long-term dependence. However, the 'market' for illegal drugs has changed considerably since the gateway hypothesis was developed and researchers in New Zealand looked at a sample of 12,992 people to see if it still held true. Only 2.6% of the sample departed from the sequence of drug use outlined in the gateway hypothesis. Use of other illicit drugs before cannabis was the most common departure found in 2.3% of alcohol users, 3% of cannabis users, 8.6% of cocaine users and 16.7% for those who had used other illicit drugs. Use of other illicit drugs before cannabis was more predominant in younger cohorts and those with more early-onset anxiety and depression. Once all the other factors had been taken into account people who departed from the gateway sequence were no more likely to develop drug dependence. Depression, anxiety and early-onset bipolar disorder were all more likely to increase the risk of drug dependence.

IQ and murder rates

People with better qualifications, higher-powered jobs and higher incomes are known to be at less risk of being murdered. However, there have been no studies into whether intelligence per se affects one's likelihood of being killed. A Swedish study looked at a group of 968,864 men who had served as military conscripts between the ages of 18 and 19. The men had taken IQ tests as part of their medical assessment when they were conscripted and were tracked over the next 20 years. 191 of them were murdered. A high IQ score was associated with a halving of the risk of being murdered and the higher people's IQ was the lower their risk.

Suicide and bereavement

It is estimated that one person in the world kills themselves every 40 seconds. For every person who commits suicide it has been estimated that six people will feel intense grief - around 35,000 people in the U.K. each year. Although the effects of such a bereavement are not necessarily more severe than bereavement following other causes of death there are certain aspects, such as stigmatisation and a sense of rejection that may make coping particularly difficult. Researchers from the University of York looked into studies on the effectiveness of interventions for people bereaved by suicide. They found evidence of some benefit from: a cognitive-behavioural family intervention of four sessions with a psychiatric nurse; a psychologist-led 10-week bereavement group intervention for children; and an 8-week group therapy intervention for adults delivered by a mental-health professional and a volunteer. Studies which compared more than one different type of intervention had produced unclear results.

Head injuries and ADHD

Some studies have suggested that injury is more common in children with Attention Deficit Hyperactivity Disorder (ADHD) while others have suggested that moderate-to-severe traumatic brain injury in school-age children results in the development of ADHD. A UK study of 62,088 children compared those (2,782) who had suffered a head injury, those (1,116) who had suffered burns and the remainder who had suffered neither. Children who had had head injuries were 1.9 times as likely to develop ADHD while children who had suffered burns were 1.7 times more likely to develop the condition.

Alexithymia and depression

Alexithymia is a state of deficiency in understanding, processing or describing emotions and has been linked to major depression, eating disorders, panic disorder and substance abuse. However, alexithymia scores have been found to decrease as people's depression improves so it is unclear whether alexithymia is a cause or a symptom of depression. An Italian study of 149 women attending antenatal clinics in the Mantova region assessed them for alexithymia, major depression and anxious-depressive symptoms at monthly intervals throughout their pregnancy. The study found that the women who developed depression had similar alexithymia and depression/anxiety symptoms to other women before they developed depression, but raised alexithymia levels after they developed depression. When the women's depression remitted their alexithymia levels decreased suggesting that their alexithymia was a symptom, not a cause, of their depression.

Disadvantage, isolation, ethnicity and psychosis

There have been a number of studies pointing to higher rates of schizophrenia and other psychoses in the Black Caribbean population in the U.K. The AESOP (aetiology and ethnicity in schizophrenia and other psychoses) study found rates of schizophrenia and manic psychosis in this group to be nine times greater than in the White British population. There has been a lot of speculation about the reasons for this disparity, most of them centring on the role of socio-economic disadvantage and racial discrimination. A study of 781 people in South-East London and Nottingham compared those experiencing a first episode of psychosis with those from a similar background unaffected by the condition. On all the indicators the people who had developed psychosis were more socially disadvantaged and isolated than healthy people. The more disadvantaged people were the more likely they were to develop psychosis, a pattern which held true for White British and Black Caribbean people. The indicators of social disadvantage and isolation were more common in Black Caribbean participants than White British ones.

Antidepressants much of a muchness

A review of more than 200 studies into the effectiveness of second-generation antidepressants has concluded that they are all equally effective although they do have different side effects. The review was carried out by the American College of Physicians which recommended that physicians make treatment decisions based on side effects, cost and patient preferences and make changes if the patient's response is not sufficient after 6-8 weeks. The guidelines issued by the college also recommend continuing treatment for four to nine months after a satisfactory response to an antidepressant in patients with a first episode of major depression. Those people who have had two or more episodes of depression should have a longer course of treatment aimed at preventing a recurrence or relapse.

PTSD, self-esteem and locus of control

A survey of 200 Kuwaiti servicemen looked into the links between exposure to trauma during the first Gulf war, post-traumatic stress disorder (PTSD), self-esteem and locus of control (people's feelings that the causes of events are due to internal or external factors). The servicemen were made up of four equal groups: those who had retired before the invasion, those who had served but not in the front line, those who had served in battle and those who had been taken captive as a prisoner of war (PoW). 31.5% of the whole sample were found to be suffering from PTSD with the rate significantly higher (48%) among the PoWs. Avoidance symptoms were the most pronounced and self-esteem was significantly lower among the PoWs and participants with PTSD. An external locus of control was associated with PTSD, anxiety and depression. Self-esteem was linked to PTSD scores while locus of control was linked to anxiety; people with an external locus of control were more prone to be anxious.

CBT for psychosis: what are the barriers?

According to National Institute for Health and Clinical Excellence (NICE) guidelines, cognitive behaviour therapy (CBT) for psychosis should be made available to service users, particularly those with persisting symptoms and treatment resistance. It has also been recommended that assertive outreach teams in the UK include CBT in their skills repertoire. However, recent evaluations in the UK have found that teams lack such provision and fail to deliver the NICE recommendations for CBT. A survey of people attending the National Forum for Assertive Outreach annual conference in 2006 asked them about the barriers to the implementation of psychosocial interventions in their area. Respondents identified a lack of organizational investment, the structured nature of CBT, caseload issues, medication issues, application to people with sensory impairment, staff apathy and staff burnout as some of the barriers against the implementation of CBT for psychosis.

Exercise and schizophrenia

There has been a growing awareness in recent years of the links between exercise and mental health. Physical exercise has been found to improve depression and anxiety but there has been little research into its effects on schizophrenia. A Turkish study of 30 people with schizophrenia divided them into two groups. One group took part in an aerobic exercise programme over a 10-week period while the other group formed a control group. At the end of the 10-week study period the participants in the exercise programme showed a significant decrease in positive and negative symptoms and an improvement in their quality of life.

Neuroscience of ADHD

A new technique for brain mapping has shed more light on the neuroscience of Attention Deficit Hyperactivity Disorder (ADHD). Large deformation diffeomorphic mapping (LDDMM) provides detailed analysis of the shape of specific brain regions, allowing for precise examination of brain structures well beyond what has been examined in previous MRI studies. Researchers from the Kennedy Krieger Institute in Baltimore scanned 113 children, aged between 8 and 13. 47 of them had ADHD while the rest were developing normally. The boys with ADHD had significantly smaller basal ganglia volumes and abnormalities in several regions of the basal ganglia which is important for basic motor response control, which may explain why children with ADHD have difficulty suppressing impulsive actions. However, the girls with ADHD had no significant brain differences compared to the unaffected children.

Stress and breast cancer

There has long been known to be a link between stress and illness and a study of an intervention designed to reduce stress in breast-cancer sufferers has had dramatic results. The study - by researchers at Ohio State University - was made up of 227 participants who had been surgically treated for stage II or III breast cancer. Half were enrolled in the intervention programme while the other half were given check-ups at regular intervals. Those in the intervention group met up weekly, in groups of 8-12 over a four-month period. A clinical psychologist taught them progressive muscle relaxation for stress reduction, problem-solving for common difficulties, how to find support from family and friends, exercise and diet tips, how to deal with treatment side effects and how to keep up with medical treatment and follow-ups. The intervention group reduced their risk of dying of breast cancer by 56% after an average of 11 years and reduced the risk of recurrence by 45%. They lived for an average of 6.1 years, compared to 4.8 years for those in the control group. The participants in the intervention group were also less likely to die of causes such as heart disease or other cancers.

Still no miracle cure for Alzheimer's

Growth hormone is naturally produced in the body and in turn stimulates the release of another hormone called insulin-like growth factor-1 (IGF-1). Studies on mice have suggested that IGF-1 might reduce beta-amyloid plaques (which are one of the main symptoms of Alzheimer's disease) and scientists have been wondering whether boosting the levels of IGF-1 in the human body might help to combat Alzheimer's. Researchers at Merck Research Laboratories in the U.S. looked into a compound called MK-677 which stimulates the release of natural growth hormone from the pituitary gland, which in turn stimulates the release of IGF-1 in other parts of the body. The researchers divided 416 people with mild-to-moderate Alzheimer's disease into two groups, one taking MK-677 and the other taking a placebo. They found that although MK-677 did boost people's levels of IGF-1 it did nothing to slow the development of the amyloid plaques.

Pregnant women's memory problems

There are anecdotal reports of women experiencing memory problems during pregnancy and these reports have been confirmed by studies of retrospective memory, such as word-learning tasks. Researchers at Australian Catholic University looked at prospective memory in pregnant women i.e. the ability to remember to do things such as attend appointments or take medication. They compared the performances of 20 pregnant and non-pregnant women on a board game called Virtual Week, which involved remembering to carry out daily tasks, and on a task in which they were required to 'check in' with a portable device at the same time four times each day. The pregnant women were no worse at the board game but were significantly worse at the second task. This impairment remained even 13 months after giving birth although by this point the women with young children were more likely to remember later that they had forgotten to 'check in.'

Can't remember what I forgot

A new book on memory loss - 'Can't remember what I forgot' by Sue Halpern - has highlighted the importance of exercise in helping to stave off memory loss. The book surveys the scientific progress - or lack thereof - in the hunt for a cure for Alzheimer's and concludes the 'one incontrovertible means of neurogenesis' is aerobic exercise. Exercise promotes new cell growth in old brains by increasing their blood volume and in turn cell growth improves memory. Exercise also increased the amount of brain-derived neurotrophic growth factor in the brain, again stimulating cell growth. Exercise was unable to prevent the growth of amyloid plaques, one of the main hallmarks of Alzheimer's disease, but it did allow the brain to cope with them better.

ADHD drugs - latest news

There remains considerable controversy over the effectiveness and ethics of prescribing medication to children with Attention Deficit Hyperactivity Disorder (ADHD). The U.S. Food and Drug Administration has approved a 30-minute onset of action for a drug called Focalin XR which will allow the manufacturers, Novartis, to claim that the drug takes effect within this time. The move is based on clinical data, including a study of 86 children aged between 6 and 12.

Predicting adolescent depression

Predicting who is likely to develop an illness allows doctors and other healthcare professionals to intervene and, with any luck, prevent the condition worsening. A team of researchers at the University of Chicago have developed a way of predicting which children will go on to develop depression after a year. They looked at risk factors at the start of the study (social and cognitive vulnerability and mood) using data from the 1995 National Longitudinal Study of Adolescent Health then aimed to develop a risk prediction index using statistical techniques. The best model was made up of 20 items.

Child psychology dropouts

People dropping out of treatment is a significant issue in all mental-health services but particularly so in child and adolescent mental-health services, with previous studies reporting dropout rates of between 28-75%. Dropping out can affect the effectiveness of treatment and lead to considerable costs for mental-health services. Researchers in Australia reviewed the files of 520 cases over a 12-month period and looked at the relationship between diagnosis and drop-out rate. Clients experiencing family problems, conduct disorder and ADHD were more likely to drop out of treatment whereas children experiencing negative life events, anxiety disorders and with no diagnosis were least likely to drop out.

Deliberate self-harm: the parents' story

Parents of children who deliberately harm themselves report finding incidents of self-harm extremely traumatic. They can experience feelings of helplessness and concerns about their ability to cope after their children are discharged from hospital and they also report a lack of information and support from healthcare professionals. There is an association between adolescent deliberate self-harm and family dysfunction and impaired adolescent-parent communication. Higher incidences of family disengagement, conflict, parental dissatisfaction and marital discord have been reported within these families as well as higher-than-average rates of affective disorder and substance abuse. A qualitative study of 25 parents involved in setting up a parents' support group in Ireland found that participants expressed the need for: support, information about suicidal behaviour in young people, skills for parenting an adolescent and advice on managing further incidents. Parents described significant difficulties in family communication, parent-child relationships and in the area of discipline following self-harm.

Exercise and mental health

Physical activity referral schemes (PARS) involve the referral of patients by health professionals (usually their GP) to a leisure provider so that they can undertake a programme of physical activity under the supervision of a qualified exercise professional. PARS have proliferated rapidly in the UK since their conception in the early nineties and are thought to be the most prevalent type of community-based physical activity programme. At the same time there has been an increasing interest in the role of physical activity in the prevention and treatment of mental-health problems and in the use of physical activity as a non-pharmacological treatment alternative. A study of 2,901 people participating in a PARS scheme between 2000 and 2003 compared the rates of referral, uptake and completion of people suffering from physical and mental illness. A similar percentage of people met up with a PARS coordinator (94% of people with a physical illness compared to 90% of people with a mental illness) but fewer people with mental-health problems (60% vs 69%) got as far as attending their first exercise sessions and fewer (22% vs 34%) completed their exercise programme.

Antipsychotics for young people

Atypical, or second-generation antipsychotics are considered to be the standard treatment for children and adolescents with early-onset schizophrenia and schizoaffective disorder. However, the superiority of atypical antipsychotics over older, first-generation antipsychotics has not been demonstrated. Researchers from a number of different U.S. universities randomly assigned 116 children to receive either the second-generation antipsychotics olanzapine or risperidone or a first-generation drug molindone. Molindone had a better response rate (50%) than olanzapine (34%) or risperidone (46%) although this difference was not statistically significant, and there was no difference between the drugs in terms of symptom reduction. Olanzapine and risperidone showed the greatest risk of weight gain and other metabolic side effects while molindone led to more of the participants saying they suffered from akathisia, an unpleasant feeling of fidgetiness and an inability to sit still.

Psychotherapy for bipolar disorder

Despite advances in drug treatment most people with bipolar disorder cannot be treated with medication alone. Up to 50% of bipolar patients do not recover from acute manic episodes within a year and only 25% achieve full recovery of function. Rates of recurrence average 40-60% in 1-2 years even when patients undergo pharmacotherapy. Patients spend as much as 47% of their lives in symptomatic states, especially depressive states and only about 40% of patients are fully adherent with medication regimes in the year following an episode. So psychotherapy still has a crucial role to play in this condition. A review of 18 trials into the effectiveness of psychological interventions by David J. Miklowitz from the University of Colorado found that family therapy, interpersonal therapy and systemic care were the most effective at preventing recurrences when initiated after an acute episode, whereas cognitive behavioural therapy and group psychoeducation were most effective when initiated during a period of recovery. Individual psychoeducational and systematic care programmes were more effective for manic than for depressive symptoms whereas family therapy and cognitive behavioural therapy were more effective for depressive than for manic symptoms.

Childhood mental-health problems

Mental-health problems are estimated to affect up to 20% of children in modern Western societies. They are divided into externalising problems such as aggression and 'oppositional defiance' and internalising ones such as depression and anxiety. Early mental-health problems often continue through childhood and adolescence into adulthood and can cause problems socialising, learning difficulties, school dropout, substance abuse, poor vocational outcomes, family violence and suicide. A three-year study of 589 children in Australia found that 'the consistent and cumulative predictors of externalising behaviours were parent stress and harsh discipline. Predictors of internalising behaviours included small family size, parent distress and parenting.'

Youth suicide - latest figures

A report into youth suicides between 1997 and 2003 has found that suicide rates for 10-19 year-olds fell by 28% between the two years. More boys than girls killed themselves and 15-19 year-olds were more likely to commit suicide than 10-14-year-olds. However, only 14% of the youths who killed themselves had been in contact with mental-health services, and only 12% of boys. Those youths who had been in contact with mental-health services and subsequently killed themselves were characterised by a diagnosis of affective disorder, a history of mental illness, 'residential instability', self-harm and substance abuse. Over half of the suicides lived with their parents but only a fifth were in full-time education.

OCD, OCPD, OCPT and EDs - perfectionism and eating disorders

Obsessive-compulsive personality disorder (OCPD) is different from obsessive-compulsive disorder (OCD) and is defined as 'a pervasive pattern of preoccupation with orderliness, perfection, mental and interpersonal control'. OCPD is associated with eating disorders (EDs) before, during and after they develop but it can be difficult to retrospectively measure people's OCPD in childhood before they developed an ED. A team of researchers at the Institute of Psychiatry in London developed the Childhood Retrospective Perfectionism questionnaire (CHIRP) and surveyed 246 people with an eating disorder, 93 informants (close friends or family members of the people with EDs), and 89 healthy controls. The CHIRP questionnaire was found to be reliable compared to the informants' memories of the ED group as children and interviews with the ED group themselves. The participants with EDs showed more experience of childhood OCPD than the control group and the more symptoms of OCPD people had had in childhood the worse their eating disorder symptoms were.

Separation, surgery and eating disorders

Mental-health problems are often triggered by adverse events and eating disorders are no exception. The effects of sexual and physical abuse in causing eating disorders have been studied but a team of researchers in Israel looked into the effects of surgery and parental separation on people's eating patterns. They followed 2,206 children through secondary school for four years and found that parental separation, oral surgery and cosmetic surgery were all significantly correlated with eating disorder symptomology. The researchers speculated that oral surgery could make the mouth associated with trauma while the cosmetic surgery could increase the youngsters' awareness of their bodily appearance thus leading on to eating problems.
