Question

Quizplus · Accepted Answer

Alcohol acts as a central nervous system depressant, primarily by enhancing the inhibitory effects of the neurotransmitter GABA. When a chronic alcoholic suddenly stops drinking, the brain remains in a hyperexcited state due to the absence of alcohol's inhibitory effects, which can lead to seizures among other withdrawal symptoms.
