Alcohol is a central nervous system depressant, which means it slows down the activity of the brain. In small doses, alcohol can cause slurred speech, drowsiness, and impaired coordination. In larger doses, it can cause blackouts, vomiting, and even death. Alcohol affects different people in different ways, depending on factors like age, weight, and how much food was consumed before drinking. However, all drinkers experience some degree of impairment when under the influence. The parts of the brain most affected by alcohol are those that control movement, vision, and judgment. As a result, drinkers may have trouble walking straight, slurred speech, and blurred vision. They may also find it difficult to make decisions or remember what happened while they were drinking. Over time, heavy drinking can lead to permanent damage to the brain. Alcoholics may suffer from memory problems and difficulty learning new information. They may also have trouble with balance and coordination. In severe cases, they may develop dementia or experience seizures. If you or someone you know is struggling with alcoholism, get help immediately. There are many resources available to those who want to recovery from this disease.
