Alcohol affects the brain quickly as it enters the blood. In a healthy person, the liver effectively distils the alcohol, helping the body to clear liquor. However, if a person drinks too much alcohol, the liver is not able to filter the alcohol fast enough, resulting in instant changes in the brain.
Over a prolonged period, too much alcohol damages both the heart and brain, resulting in permanent damage.
Drinking too much alcohol has negative effects on neurotransmitters in the brain, reducing their effectiveness. Alcohol also destroys brain cells and brain tissue. Some people with a history of excessive alcohol abuse will develop nutritional deficiencies that cause further deterioration of brain function.
