Researchers analyzed data from more than 36,000 adults that found a link between drinking and reduced brain volume that begins at an average consumption level of less than one alcohol unit a day — the equivalent of about half a beer — and rises with each additional drink. Heavier drinking was associated with an even greater toll. People who drink heavily have alterations in brain structure and size that are associated with cognitive impairments. But according to a new study, alcohol consumption even at levels most would consider modest — a few beers or glasses of wine a week — may also carry risks to the brain. light-to-moderate alcohol consumption was associated with reductions in overall brain volume. The team reported their findings in the journal Nature Communications.
