Why Does Alcohol Withdrawal Cause Seizures and What Actually Happens in the Brain

One of the most serious and frightening complications of alcohol withdrawal is seizures. Medical supervision is most critical during the first 72 hours when severe symptoms like delirium tremens may develop.

Alcohol withdrawal symptoms represent a serious cause of shaking after drinking, occurring when the body has become physically dependent on alcohol.
