Prolonged use of alcohol is toxic to neurons and can result in neuron death. Continued use of alcohol can cause atrophy of the cerebellum – a shrinkage of the brain. This results in ataxia, a degenerative disease of the nervous system, which is irreversible.
Alcohol has a profound effect on the complex structures of the brain. It blocks chemical signals between brain cells (called neurons), leading to the common immediate symptoms of intoxication, including impulsive behavior, slurred speech, poor memory, and slowed reflexes.

However, BAC does not correlate exactly with symptoms of drunkenness and different people have different symptoms even after drinking the same amount of alcohol.
The frontal lobe of the brain, responsible for many critical functions including reasoning, behavior control, memory, and motor function, takes a heavy hit when you drink in excess. Years of alcohol abuse can damage this area of the brain extensively, leading to a wide variety of issues including memory loss and the inability to think rationally.
