Being a social drinker can apparently cut the risk of developing Alzheimer’s disease. Loyola University scientists say moderate drinkers are less likely to be stricken with dementia and cognitive impairment than those who abstain. Researchers say the findings about drinking and Alzheimer’s are similar to what scientists have learned about moderate drinking and some coronary conditions. Moderate drinking is defined as a drink a day for women and two drinks a day for men. The study warns that guzzling three to five drinks a day was associated with a higher chance of dementia.
