Heavy Drinking Linked to Brain Lesions and Higher Alzheimer's Risk in New Study
A new study highlights the potential brain health risks of heavy drinking. Researchers report that consuming eight or more alcoholic drinks per week is associated with brain lesions called hyaline arteriolosclerosis, which reflect damaged blood vessels and reduced blood flow that can affect memory and thinking.
The findings also point to an increased presence of tau tangles, a biomarker connected to Alzheimer’s disease, among heavy drinkers and those with a history of heavy drinking. The research further suggests that former drinkers may have lower brain mass and poorer cognitive performance, while heavy drinkers showed a higher likelihood of earlier mortality compared with those who abstain.
