There is no such thing as a "safe" level of drinking, with increased consumption of alcohol associated with poorer brain health, according to a new study.

In an observational study, which has not yet been peer-reviewed, researchers from the University of Oxford studied the relationship between the self-reported alcohol intake of some 25,000 people in the UK, and their brain scans. The researchers noted that drinking had an effect on the brain's gray matter—regions in the brain that make up "important bits where information is processed," according to lead author Anya Topiwala, a senior clinical researcher at Oxford. "The more people drank, the less the volume of their gray matter," Topiwala said via email.

"Brain volume reduces with age and more severely with dementia (痴呆). Smaller brain volume also predicts worse performance on memory testing," she explained. "While alcohol only made a small contribution to this (0.8%), it was a greater contribution than other 'modifiable' risk factors," she said, explaining that modifiable risk factors are "ones you can do something about, in contrast to aging."
