Grief and the brain

Everyone experiences grief at some point in their life. Most people move on and accept the loss but for a substantial minority - those suffering from complicated grief - it is impossible to let go, and, even years later any reminder of their loss (such as a picture or a memory) brings on a fresh wave of grief and yearning. Complicated grief can be debilitating involving recurrent pangs of painful emotions, intense yearning, longing and searching for the deceased and a preoccupation with thoughts of the loved one. A team of researchers at UCLA, U.S. examined what goes on in the brain when we experience grief by showing 23 participants - 11 of whom had complicated grief - photographs of dead loved ones while they underwent an MRI scan. All the groups showed increased activity in the dorsal anterior cingulate cortex and the insula, areas of the brain implicated in perceptions of pain. However, those women suffering from complicated grief also experienced increased activity in the nucleus accumbens, a region of the brain most commonly associated with reward and one that has also been shown to play a role in social attachment such as sibling and maternal affiliation.

Anxiety and depression in children

A long-term study of 900 families in Norway followed children from 18 months through to adolescence looking into the causes of childhood anxiety and depression. 10-20% of all children and young people will, in the course of growing up, display enough symptoms of anxiety and depression to qualify for a diagnosis. Maternal distress symptoms, family stress and a lack of support in the child's pre-school environment all led to an increase in depression and anxiety symptoms at 12-13. Girls were more likely to develop emotional problems at 12-13 than boys. They were more likely to churn problems over and could be more vulnerable as they go through puberty earlier than boys. Timid and shy children were at a greater risk of developing depression and anxiety. Timid/shy children who were inactive were at three times the risk of developing depression and anxiety than timid/shy children who were active.

Weight, perception and happiness in teenagers

A study of 7,000 German teenagers looked into their perceptions of their weight, their actual weight and their quality of life. Only about 18% of the sample were actually overweight, with 7-8% of them actually being underweight. However 55% of the girls and 36% of the boys thought that they were too fat. The children's quality of life was linked to their perception of their weight rather than their actual weight and this was particularly marked with the girls. Normal-weight girls who thought they were too fat had a reduced quality of life whereas overweight girls who were happy with their weight had the same quality of life as normal-weight ones.

Automated scans for Alzheimer's

In Alzheimer's disease nerve cell death and tissue loss cause all areas of the brain, especially the hippocampus to shrink. When Alzheimer's is diagnosed early drug treatment can help to improve or stabilize patient symptoms. MRI scans can be used to measure anatomical changes in the brain but evaluating brain shrinkage is a complex, lengthy process. Researchers in France have developed an automated system for doing this, which, they hope, will speed things up considerably. The researchers used the new system to scan 25 people with Alzheimer's disease, 24 patients with mild cognitive impairment (MCI) and 25 healthy older adults and found the hippocampus had shrunk by 32% in those with Alzheimer's and 19% in those with MCI. These figures were consistent with those found by manual methods of MRI interpretation but were produced much more quickly.

Physical toll of anxiety

A review of the evidence by Harvard Women's Health Watch looked at the links between anxiety and physical illness. A recent New Zealand study found links between high levels of anxiety and the development of irritable bowel syndrome. Most studies have found a high rate of anxiety symptoms and panic attacks in people with chronic respiratory disorders such as asthma or chronic obstructive pulmonary disease (COPD) with women at greater risk than men. In studies involving COPD patients anxiety has been associated with more frequent hospitalization and more severe distress. Anxiety disorders have also been linked to the development of heart disease and to heart attacks in people who already have heart disease. Two recent studies concluded that among people with heart disease those suffering from an anxiety disorder were twice as likely to have a heart attack.

Tai chi and sleeping

More than half of older adults have difficulties sleeping although most don't seek treatment. Some take sedatives but these can lead to daytime confusion, drowsiness, falls and fractures while behaviour therapies can be costly and not always available closer to home. Physical exercise has been found to enhance sleep quality but older people sometimes have difficulties with this. Tai chi uses gentle, slower movements and is more suitable for older people. A study of 112 healthy adults between the ages of 59 and 86 divided them into two groups. The first group practiced 20 simple tai-chi moves while the other group attended health education classes that included advice on stress management, diet and sleep habits. Compared to the other group the tai-chi group showed improved sleep quality, less drowsiness, improved concentration, longer sleep and less sleep disturbance.

Men coping with women's drinking

The impact of having a close relative with a drinking problem can be considerable. The family directly experience the consequences of the drinking behaviour and attempts to cope can produce a variety of negative emotional, psychological, physical and social reactions. And, in turn, family members' coping strategies can have a role in the progression of people's drinking problems. Despite a significant amount of research looking at the families of problem drinkers, little is known about male partners of problem drinkers. Some studies have found that men use a withdrawal style of coping behaviour either physically (by going into a different room or going out) or emotionally (by avoiding confrontation or an active involvement in the problem). A study of 29 male partners of female problem drinkers found that, in fact, the men were more likely to use engaged coping behaviours, trying to change their partners' drinking behaviour, than withdrawal ones. However, the longer the women had had a drink problem the more likely the men were to use a passive or withdrawn coping style.

Methadone and buprenorphine

Methadone is the usual treatment for heroin addicts. It improves physical and mental health and social functioning and reduces criminal behaviour. However, people can die of an overdose of methadone and some people argue that it prolongs the period of dependence as it takes a long time to come off it. In 1999 buprenorphine was licensed for use in treating heroin addiction. It is less harmful in overdose and easier to withdraw from although methadone is slightly more effective and significantly cheaper. However, little is known about the views of heroin addicts themselves on methods of treatment. A study of 42 addicts in Norwich found that those taking buprenorphine viewed methadone more negatively and buprenorphine more positivelythan those taking methadone. Those taking methadone apperared to do do on the basis of familiarity whereas those taking buprenorphie appeared to be attracted by their beliefs that it would block heroin more effectively, reduce cravings, give less intoxication and be earlier to stop taking than methadone.

Resetting body clocks for people with dementia

Older people with dementia have disturbed body clocks which can contribute to cognitive decline and problems with mood, behaviour and the activities of everyday living. Bright light and melatonin are known to help with body-clock problems and a study of care-home residents in Holland found that bright light slowed cognitive decline by 5%, reduced symptoms of depression by 19% and helped to slow down loss of functional ability. Melatonin improved sleep patterns but worsened mood unless it was accompanied by bright light.

St John's Wort for ADHD

St John's Wort is best known as a treatment for depression but is also one of the most popular complementary treatments for children with Attention Deficit Hyperactivity Disorder (ADHD). A U.S. study of 54 children compared St John's Wort to a placebo in an 8-week trial. By the end of the trial the researchers found that more of the children (51.9% vs 44.4%) in the placebo group had shown an improvement and by a greater amount.

Parents' insomnia and children's health problems

A study of 798 teenagers with an average age of 14 by researchers at the University of Pittsburgh looked into not only their own sleeping patterns but also the sleeping patterns of their parents. The study found that children whose parents had sleep problems were more likely to have insomnia themselves, to be tired during the day and to use hypnotics (sedatives). Children of insomniac parents were also more likely to suffer from anxiety, depression, and suicidal thoughts/attempts.

Alone and depressed of Hicksville

A study of women over 18 living in rural areas in the U.S. has found that unmarried women living in these areas are at a greater risk of depression. The study found that single or divorced women were more prone to poor self-rated health than those who were married.

Naltrexone for gambling problems

It is estimated that between 1 and 3% of the population has a gambling problem. The principal treatments for gambling problems are usually psychological but a new study by researchers at the University of Minnesota has found that a drug usually used to treat alcoholism can also help gamblers. The study, of people between the ages of 18 and 75 who gambled between six and thirty-two hours a week, compared the drug naltrexone to a placebo. By the end of the 18-week trial 40% of those taking naltrexone had quit gambling for at least a month, compared to only 10% of those taking the placebo. Naltrexone had few side effects and was equally effective in men and women.

9/11 and PTSD - seven years on

Nearly seven years after the event a survey of 11,000 New Yorkers has shown that the attacks of September 11, 2001 have had lasting psychological consequences. The survey found that Lower Manhattan residents had developed post-traumatic stress disorder (PTSD) at three times the usual rate. The rate among residents (12.6%) matched that (12.4%) previously reported among rescue and recovery workers. Apart from injured residents, 38% of whom developed PTSD symptoms, the most affected groups were those who witnessed violent deaths and those who were caught up in the dust cloud as the twin towers collapsed; roughly 17% suffered from PTSD in each of these groups. Divorced people, women, black and Hispanic people and those with lower levels of education and income were all at a higher risk of PTSD.

What makes wise old heads tick?

Previous research has shown a positivity bias in older people who seem to be able to control how much attention they give to negative situations and are less upset by them. A study by researchers at Duke University, in the U.S., asked groups of older and younger participants to rate the emotional content of standardized images as positive, neutral or negative while their brain was monitored with an MRI machine. The older participants rated the images as less negative than the younger ones and had increased interaction between the amygdala - a part of the brain which is involved with emotions - and the anterior cingulate cortex, a brain region involved in emotional control. The researchers hope that an understanding of the positivity bias of older people can help with treatments for anxiety and depression.

Overtime and mental health

A Norwegian study of over 10,000 people has found that those who work more overtime are more at risk of anxiety and depression. The study compared those people who worked 40 hours per week or less with those who worked between 41 and 100 hours. Rates of depression increased from 9% in men who worked normal hours to 12.5% in those who worked longer while for women there was an increase from 7% to 11%. In both sexes rates of anxiety and depression were higher among workers who were less skilled and had lower incomes. The relationship was strongest among men who worked the most overtime (49-100 hours). People who worked such long hours were more likely to be engaged in heavy manual labour and shift work and to have lower levels of skills and education.

Plaques and prediction in Pittsburgh

A team of researchers at the University of Pittsburgh, U.S. have been looking into the beta-amyloid protein plaques found in the brains of people suffering from Alzheimer's disease. The team used a positron emission tomography (PET) scan and a radioactive substance that bound to the plaques to follow 56 people, between the ages of 65 and 80, at yearly intervals over four years. About 60% of the participants with mild cognitive impairment (MCI) had plaque levels similar to people with Alzheimer's while the rest had no detectable plaque. By the end of the study only those with plaques had developed a clinical diagnosis of Alzheimer's. About 25% of the 'healthy' control group - who had neither MCI nor Alzheimer's - had significant deposits of amyloid plaque. The team hope their new techniques of detecting plaques within the brain will lead to earlier diagnosis of, and treatment for, Alzheimer's.

Insight and OCD

Insight - in mental health terms - is being aware that one's behaviour and/or feelings are not healthy or usual. In relation to obsessive-compulsive disorder (OCD) insight can be viewed as occuring on a continuum ranging from full awareness of the absurdity of obsessions and compulsions to a total lack of any such awareness. An Italian study of insight among 75 patients with OCD found that poor or absent insight was associated with higher perceived expressed emotion*, a higher severity of OCD symptoms, higher familial perceived criticism and more compulsions and depressive symptoms.

Adolescent OCD - intensive, inpatient treatment

Between 2-3% of people are thought to suffer from obsessive-compulsive disorder (OCD) at some point in their lifetimes and one-third of adults who suffer from OCD started to suffer in their childhood. Cognitive behaviour therapy is the first choice of treatment for paediatric OCD with serotonin reuptake inhibitors (SRIs) being recommended for more severe cases. However, one quarter of children do not recover after CBT. One alternative for these children is an intensive, inpatient programme with multidisciplinary support. A study of 23 patients being treated with such a programme in the U.S. found it led to a significant improvement and it is hoped that larger trials in the future will confirm these encouraging results.

Conduct disorder and schizophrenia

Conduct disorder prior to the age of fifteen has been found to be much more common among men and women with schizophrenia than among those without, with one study finding that 40% of people who had developed schizophrenia by the age of 26 had fulfilled the diagnostic criteria for conduct disorder by the age of 15. A UK study of 205 men and women with severe mental illness found that conduct disorder before 15 was associated with an increased risk of being assaulted, aggressive behaviour in the six months prior to the study and convictions for violent crimes.

Mental health and ME

A study of 3,035 people in the UK followed them for 43 years of their life and assessed them for chronic fatigue syndrome/ME (CFS/ME) at 53 years of age. 34 (1.1%) of the participants reported a diagnosis of CFS/ME at 53. CFS/ME was more common among women and those who had had mental-health problems between the ages of 15 and 36 were 2.65 times more likely to develop CFS/ME later. Increased levels of psychiatric illness - in particular depression and anxiety - were present prior to the occurence of fatigue symptoms. The more severe people's mental health problems were the more likely they were to develop CFS/ME.

Cannabis, brain damage and psychosis

There is conflicting evidence regarding the long-term effects of regular cannabis use. Although there is a growing literature suggesting that long-term cannabis use is associated with a wide variety of health problems many people in the community, as well as cannabis users themselves, believe it is relatively harmless and should be legally available. Animal studies have shown that long-term cannabis administration can affect the hippocampus but only a handful of brain-imaging studies have been undertaken in humans. An Australian study compared fifteen long-term cannabis users with a sixteen-strong control group and found that the hippocampi and amygdalas of the cannabis users were significantly smaller. The more people had smoked cannabis the smaller their hippocampi were and the more likely they were to have 'sub-threshold' psychosis symptoms. Positive symptom scores - delusions, hallucinations etc - were also associated with cumulative exposure to cannabis.

Early intervention for untreated psychosis

The duration of untreated psychosis (DUP) - the time from the onset of psychotic symptoms to the start of adequate treatment - is one of the most important factors in the course of the condition and a shorter DUP has consistently been shown to correlate with a better course and outcome for all the symptoms of psychosis. Researchers in Scandinavia created a comprehensive, early-detection system for psychosis and launched a public information campaign in one area, and compared it to another area without early detection. The first-episode patients from the early-detection area had significantly lower DUP, better clinical status and milder negative symptoms at the start of the treatment. After a year there was still a difference in negative symptoms between the groups. After two years there were still differences in negative symptoms, depression and cognition between the two sets of patients.

Sleep problems and depression and anxiety in children

Many children can suffer from difficulties in sleeping, however, for a small number of them this could be linked to depression and anxiety. An Italian study of 322 children between the ages of 7 and 11 compared those with depression, those with depression and anxiety, and a control group of unaffected children. 82% of the depressed children reported sleep problems, compared to only 5% of the controls. 42% of those with depression and anxiety and 29% of those with depression had problems getting to sleep. Depressed and depressed-and-anxious children had a significant tendency to a later bedtime and more fragmented sleep. 20% of the depressed-and-anxious children and 17% of the depressed children shared their parents' bed compared to only 5% of the control group.

Happy marriage and sweet dreams

Sleep plays a vital role in promoting health and well-being. A study of 1,938 women by researchers at the University of Pittsburgh compared their marital happiness with their sleep quality. The study found that higher levels of marital happiness were associated with a lesser risk of having multiple sleep complaints, but only among White women.

Topiramate for alcohol problems

Topiramate is a drug currently used to treat seizures and migraines. However, a 14-week study of 371 alcoholics in Virginia, U.S. has found that it could also be useful in treating people with alcohol problems. Compared to a placebo topiramate decreased heavy drinking, lowered liver enzymes, cholesterol, body mass index and blood pressure. Topiramate also led to a decline in obsessive thoughts and compulsions about alcohol and a greater improvement in people's quality of life and a reduction in sleep disturbances.

Inflammation and depression

There are clinical parallels between depressive symptoms and the symptoms of certain inflammatory disorders. Now researchers from the University of Miami have found genetic differences in inflammation-related genes that are associated with susceptibility to major depression. The researchers found the differences in a study of 615 Mexican-Americans in Los Angeles by comparing those with and without depression. The genes involved are also linked to psoriasis and asthma both of which are known to co-exist with depression and be brought on by psychosocial stressors.

Could stiff upper lips be back in fashion?

The conventional wisdom in popular culture and psychology is that it is better to talk about one's feelings than bottle them up. However, researchers at the University of Buffalo in the U.S. have called this into question. Using a large national sample the researchers tested people's responses to the terrorist attacks of 9/11 beginning immediately after the event and continuing for the following two years. In an online survey the respondents were given a chance to express their thoughts and feelings on the day of 9/11 and a few days afterwards. The researchers then compared people who chose to express their thoughts and feelings to those who didn't. The people who kept a stiff upper lip did better than those who talked about their feelings. Various alternative explanations were looked at to explain the difference but nothing else accounted for the difference between the two groups.

Job stress and depression

An Australian study into the links between workplace stress and depression has found that, in people of working age, almost one in six cases of depression are caused by stress at work. The study defined stressful work conditions as a combination of high job demands and low control over how the job gets done. The researchers found that more women than men experienced stress and that stress was more likely in lower-skilled occupations. Nearly one in five working women and one in eight working men with depression had problems due to job stress.

Genetics and schizophrenia

Schizophrenia affects approximately 1% of the world's population. About 40% of cases are thought to be inherited with the other 60% occuring spontaneously in people with no family history of the disease. A study of 1,077 people from the Afrikaner population in South Africa found that rare, spontaneous genetic mutations accounted for at least 10% of the non-familial cases of the disease. The researchers found mutations, either a gain or loss of genes, in 15 individuals diagnosed with schizophrenia that were not present in the chromosomes of either biological, unaffected parent. Chromosome 22 was found to be particularly significant.

Bipolar disorder and substance abuse

There has long been thought to be a link between child and adolescent bipolar disorder and an increased risk of substance abuse but it is not clear whether this is due to bipolar disorder itself or co-existing conditions such as attention-deficit hyperactivity disorder (ADHD), conduct disorder or anxiety disorders. A U.S. study of 203 children compared those with bipolar disorder to an unaffected control group. The incidence of alchohol abuse, drug abuse and smoking was significantly higher in the children with bipolar disorder and overall the rate of substance abuse was much higher (34% vs 4%) among those with bipolar disorder. The onset of bipolar disorder preceded the onset of substance abuse and those who developed bipolar disorder in adolescence were more likely to develop drug problems than those who developed the condition in childhood. When adjusted to account for co-occuring behavioural and psychiatric conditions the results still indicated significantly higher risk in the bipolar group.

Exposure therapy and PTSD

People who develop acute stress disorder during or soon after a traumatic event are likely to go on to develop post-traumatic stress disorder (PTSD) which is associated with other mental and physical illnesses, a reduced quality of life and increased health-care costs. Exposure therapy, in which recent trauma survivors are instructed to relive the troubling event, and cognitive restructuring, which focuses on changing maladaptive thoughts and responses to a traumatic event, have been used as interventions to prevent people with acute stress disorder going on to develop full-blown PTSD. However, there is evidence that some clinicians do not use exposure therapy because it causes distress for recent trauma survivors. An Australian study with 63 participants compared those taking part in exposure therapy with those receiving cognitive restructuring. After the treatment fewer people in the exposure-therapy group (37% vs 63%) met the criteria for PTSD and more (47% vs 13%) met the criteria for full remission. Despite concerns that patients would not be able to manage the distress elicited by prolonged exposure there was no difference in drop-out rates between the two groups.

Better foster care yields better prospects

People who have been in foster care can often suffer from higher rates of mental and physical health problems. A study of 659 fostered children by researches from Harvard Medical School compared those going through a private system - staffed by highly-trained social workers with low caseloads and good access to quality services - to those going through the normal public system (because of a lack of spaces on the private one). Those children going through the private programme had significantly more stable placements (32.7 vs 13.3 months); were at consistently lower risk of foster parent neglect, physical abuse and sexual abuse; were far less likely to suffer from depression (11.3% vs 24.3%), anxiety disorders (28.8% vs 43%) and substance-use disorders (5.1% vs 11.1%) and a lower prevalence of ulcers (7.4% vs 13%) and cardio-metabolic conditions (14.9% vs 22.6%).

Middle-aged anorexics

The number of middle-aged people being treated for eating disorders has increased during the last decade. Body image issues and body dissatisfaction increase as the human body undergoes natural changes such as greying hair, wrinkles and weight gain and it has been theorized that mid-life eating disorders could be caused by mid-life transitions such as the loss of parents, siblings or children; traumatic illness and empty-nest syndrome. In some cases this may be a recurrence of an eating disorder which first appeared in childhood but little is known about women developing an eating disorder for the first time at this age. A study of 50 women with a first eating-disorder onset at age 40 or above found that compared to younger patients middle-aged anorexics had less severe and less-common symptoms; a predominance of 'pure' restricting behaviours and a rarity of bulimia; similar rates of depression and anxiety but of less severity; fewer substance-use disorders and substantially greater histories of sexual abuse.

CBT for psychosis

Psychosis can recur throughout people's lives leading to long-term disability. Reviews of studies have shown that combining drugs with psychological interventions - specifically cognitive behavioural therapy (CBT) and family intervention - improves clinical outcome. Family interventions have been shown to produce a reduction of around 20% in relapses but the evidence for CBT is less clear. A study of 301 patients and 84 carers found that both CBT and family intervention had no effect on rates of remission and relapse or on days in hospital at 12 or 24 months. CBT showed a beneficial effect on depression after two years whereas there were no effects for family intervention. In people with carers CBT significantly improved delusional distress and social functioning.

Antipsychotics and diabetes

Diabetes is one of the most common chronic diseases affecting 3-4% of the population. This proportion is predicted to double by 2030, largely as a result of an ageing population and an increased incidence of obesity. Type 1 diabetes, which begins in childhood, accounts for 10-15% of cases with type 2 diabetes, which begins in adulthood, making up the remainder. The prevalence of diabetes has been reported to be two to three times higher among people with schizophrenia than in the rest of the population and there has been increasing concern that antipsychotics - particularly newer, second-generation ones - are associated with an increased risk. A review of 14 studies compared the relative risk of first- and second-generation antipsychotics and concluded that the second generation ones led to a 32% increase in the risk of developing diabetes.
