Some studies have also suggested that moderate drinking may be good for the brain, but most of these focused on elderly people and their recent drinking habits, making it hard to draw any conclusions about the effect of lifetime drinking patterns. So Severine Sabia, a researcher at Inserm, and her colleagues analyzed data from a large UK database to track alcohol consumption from middle age and its effect on dementia in later life. Among more than 9,000 middle-aged people ages 35 to 55, who were followed for about 23 years, those with drinking habits at the two extremes — people who abstained from drinking, as well as those who drank more than around 14 glasses of wine a week — showed higher risk of dementia than those who drank one to eight glasses of wine a week.
