Moderate wine drinking could cut people's risk of developing Alzheimer's disease. Researchers from Boston University Medical Center studied 5,033 men and women from Tromso in northern Norway. The participants had an average age of 58 and were followed over a seven-year period. Women who consumed wine at least four times over a two-week period scored better, on average, on cognitive-function tests than those who drank wine once or less while not drinking was associated with significantly lower cognitive performance. The researchers were able to adjust for the effects of age, education, weight, depression and cardiovascular disease in their study but not for those of diet, income or profession. Over the last 30 years there have been 68 studies into the links between moderate alcohol consumption and cognitive function involving 145,308 participants. Most of these studies have shown an association between light-moderate consumption and better cognitive function and a reduced risk of dementia.
