Would that crisp Chardonnay or cool, refreshing lager go down as guiltlessly if you knew that every sip contributed, imperceptibly, to the shirnkage of your brain?
A new study has found that, over time, drinking alcohol, whether moderately or heavily, was associated with decreased brain volume. And although heavy drinkers had significantly less brain volume than light or moderate drinkers, only abstainers were found to have no alcohol-ralated brain astrophy. The effect was the greatest in women.
Whether the loss of brain volume was caused by alcohol, and whether it contributed to any decreased cognitive function, remains to be seen. But the study is the latest cautionary note in the perplexing issue of whether moderate alcohol consumption is good for one's heart but not so good for the brain.
"That's the big question," said lead author Carol Ann Paul, a researcher with Wellesley College. "I would be reluctant to tell people not to enjoy their drink a day. But that is something to think about."
The research, which included MRI brain scans of 1,839 people who are part of a Framingham study, was presented Webnesday at the American Academy of Neurology annual meeting. Basedon their drinking habits, the people, who ranged in age from 34 to 88, were divided into five groups; non-drinkers; (one to seven drinks a week); moderate drinkers (eight to 14 drinks a week); and heavy drinkers (more than 14 drinks a week); Their average age was 61.
Compared with the non-drinkers, all of the groups had progressively greater amounts of decreased brain volume, with the biggest decrease in the heavy drinkers. The heavy drinking group had a 1.25 percent decrease in brain volume. Although, in general, decreased brain volume is associated with decreased cognitive function, the study did not measure that.
