Does alcohol kill brain cells?
It is a myth that drinking kills brain cells. Instead, alcohol damages the brain in other ways, for instance, by damaging the ends of neurons. This can make it difficult for those neurons to send important nerve signals. Alcohol may also damage the brain by increasing the risk of strokes, head injuries, and accidents.
Does alcohol affect memory?
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.
Does alcohol permanently damage the brain?
Short-term symptoms indicating reduced brain function include difficulty walking, blurred vision, slowed reaction time, and compromised memory. Heavy drinking and binge drinking can result in permanent damage to the brain and nervous system.
What Cannot cross the blood-brain barrier?

Can the brain heal itself from alcohol?
According to a recent article on recovery of behavior and brain function after abstinence from alcohol, individuals in recovery can rest assured that some brain functions will fully recover; but others may require more work.
