Alcohol and the Brain: One Drink a Day Associated with Brain Shrinkage

There are many conflicting studies on how alcohol consumption can impact a person’s health, with some studies suggesting light drinking can protect against coronary heart disease and others concluding that drinking can increase your risk for cancer. What does research say about alcohol and the brain? Dr. Remi Daviet joins the podcast to discuss his latest study that found that just one alcoholic drink a day was associated with brain shrinkage, and drinking more could increase that rate exponentially over time.
