What happens to the body during a blackout? Alcohol impairs your ability to walk, speak, react, and remember events. It also lowers inhibition, hinders impulse control, and affects decision-making. The reward pathway in the brain regulates these activities.

Do blackouts cause brain damage?

Long-term effects can occur from drinking too much regularly, but again, brain damage is not directly caused by blacking out. A person who drinks heavily for a long time, and may experience frequent blackouts as a result, is more likely to experience general memory loss even if they are not intoxicated.

Can you blackout and still be awake?

Can’t remember anything after drinking?

Alcohol affects short-term memory by slowing down how nerves communicate with each other in a part of the brain called the hippocampus. The hippocampus plays a significant role in helping people form and maintain memories. When normal nerve activity slows down, short-term memory loss can occur.
