Though long term alcohol abuse can cause memory loss and impair cognitive function, Small amounts of alcohol might, in effect, make brain cells more fit.
Here's some news for booze lovers: moderate drinking can lower risks of Alzheimer's disease and other cognitive loss, according to researchers who reviewed 44 studies.
In more than half of the studies, published since the 1990s, moderate drinkers of wine, beer and liquor had lower dementia risks than nondrinkers. In only a few studies were there increased risks.

The pathological damage and vast social havoc from addiction to and abuse of alcohol are well known, and of necessity should continue to receive primary attention by doctors, scientific researchers and health professionals," Collins and colleagues write.

Long-term alcohol abuse can cause memory loss and impair cognitive function. It's unknown why moderate alcohol use appears to have the opposite effect. One theory is that the well-known cardiovascular benefits of moderate alcohol consumption also can reduce the risk of mini strokes that cause dementia.

Small amounts of alcohol might, in effect, make brain cells more fit. Alcohol in moderate levels stresses cells and thus toughens them up to cope with major stresses down the road that could cause dementia.
For most people who drink responsibly and in moderation, there's probably no reason to quit. But because of the potential for alcohol to be abused, Collins and Neafsey do not recommend that abstainers begin drinking.
The researchers note there are other things besides moderate drinking that can reduce the risk of dementia, including exercise, green tea, education and a Mediterranean diet high in fruits, vegetables, cereals, beans, nuts and seeds.
Moreover, there are times when people should never drink, including adolescence, pregnancy and before driving, Collins said.
