Washington: The more you drink, the more your brain shrinks, scientists said on Sunday.

Many studies have shown that moderate alcohol consumption can be good for heart health.

Researchers led by Carol Ann Paul of Wellesley College in Massachusetts wanted to see if it also protected against the inevitable loss of brain volume that people experience as they age. It did not.

In fact, lifelong teetotallers had the least brain-volume loss, with former drinkers, moderate current drinkers and heavy current drinkers experiencing progressively more brain shrinkage, they wrote in the journal Archives of Neurology.
