Alcohol is one of those things that can be great, but can also be dangerous. Researchers from two universities found three stages of life when using alcohol can be the most damaging to the brain. It turns out those over age 65, those in their late teens, and babies in the womb are most at risk when it comes to the harmful effects of booze. Each of the phases correlate with “dynamic brain changes,” making the brain particularly sensitive to alcohol. Unborn babies are at high risk because they are facing a critical time for development, while alcohol use disorders in those ages 65 and up has been correlated with dementia, and teens who drink too much can actually face reduced brain volume and poorer white matter development— and both are critical for the brain to function efficiently. One of the researchers notes, “We need a better public awareness of the possible damaging effects of alcohol on the brain at opposite ends of the lifespan.”
