Even Low Levels of Alcohol Could Damage Your Brain, Study Finds

A new MRI study of 45 healthy adults found that higher monthly alcohol intake was linked to lower brain perfusion and thinner cortical tissue.

The age effect was stronger in older adults, suggesting alcohol-related brain changes may compound over time.

The study relied on self-reported drinking and a one-time MRI snapshot, so it shows correlation, not causation.

The findings raise questions about whether there is truly a safe low-risk threshold for alcohol use.
