According to a new study, just one pint of beer or an average glass of wine a day may shrink the overall brain volume, with the damage increasing with a rise in the number of drinks daily.

The brains of individuals of that age, who reported drinking three alcohol units a day, had both white and gray matter reductions which looked like 3.5 years have been added to their brain age.
