As someone drinks, dopamine increases in the brain. This results in pleasant feelings and elevated. However, alcohol is primarily a central nervous depressant. This means that is slows down the body and brain – cognitive abilities, motor skills, and the ability to stay conscious and coherent all decrease as alcohol is continually consumed.This is where alcohol detox comes into play.
Habitual drinking can cause both tolerance and dependence. The brain gets accustomed to the dopamine-altering effects of alcohol, as well as the general sedation. When someone tries to detox after a period of frequent alcohol use, withdrawal effects occur, which are precisely the opposite of being drunk.
