The intoxified brain does not function well (whatever its owner may temporarily believe), and the deleterious effect on intellectual function of long-term assault with heavy alcohol is well known. It comes as a pleasant relief to find that moderate wine consumers have improved cognitive function compared with both heavy wine consumers and non-drinkers, and are less likely to develop dementias such as Alzheimer’s disease. Studies suggest that resveratrol may additionally be ‘dementia-protective’ by increasing the brain’s blood flow as well as directly benefiting the cells and tissues of the brain.
