A glass of wine could ward off dementia

A new study suggests a glass or two of wine a day -- but no more -- could help older adults fight off dementia.Researchers at Wake Forest University found moderate drinkers, age 75 and older, have a lower risk of dementia than seniors who don't drink at all. However, moderation is the key: the study shows people who drink excessively are more likely to develop dementia than those who abstain completely.

Researchers also said they do not recommend that non-drinkers begin to use alcohol to try to prevent dementia.
