Two new studies challenge the theory that a glass or two of wine a day may lower the risk of dementia in old age.
California researchers tracked about 1,300 women from their mid-sixties into their eighties. They found that women who said they drank more in the past than at the start of the study were at a 30 percent higher risk for developing mental impairment.
Moderate drinkers were approximately 60 percent more likely to develop mental problems near the end of the study.
Non-drinkers who became drinkers during the study found that senior drinkers who binge-drank were more likely to experience a decline in their mental function.
Experts recommend no more than one drink a day for women and no more than two a day for men. But, this research suggests that we may need to cut back as we age.
