What is a common sign of alcohol withdrawal?

A common sign of alcohol withdrawal is grand mal seizures, which occur due to the sudden cessation of alcohol consumption after prolonged use. When a person who has developed a physical dependence on alcohol stops drinking, the brain experiences hyperactivity as it adapts to the absence of alcohol, which acts as a central nervous system depressant. This hyperactivity can manifest as seizures, particularly within 6 to 48 hours after the last drink, marking a critical phase of withdrawal.

Other symptoms of alcohol withdrawal can include tremors, anxiety, nausea, and in severe cases, delirium tremens, but the occurrence of grand mal seizures is particularly noteworthy as it indicates a significant level of physiological dependence and the potential for serious complications if not managed properly.

In contrast, options involving increased appetite, euphoria, or hallucinations do not represent the typical signs of withdrawal. Increased appetite is generally not associated with alcohol withdrawal; instead, appetite may decrease. Euphoria might occur during periods of alcohol use rather than withdrawal, and hallucinations, while possible in severe cases of withdrawal, are not as common as seizures and are more typically related to delirium tremens or significant alcohol-related psychosis.
