British researchers say middle-aged men risk a faster decline in mental ability as they age if they've been drinking heavily for years.
Their study found that over a decade, the added decline was the equivalent of about two extra years of aging for a combined measure of mental abilities like reasoning. For memory, it was the equivalent of six years of aging.
It's no surprise that heavy alcohol consumption can affect the brain, but the study focused on an age range that has received much less attention from alcohol researchers than the elderly and college students.
The work was published online Wednesday by the journal Neurology.
