Which factors increase the risk of delirium tremens during alcohol withdrawal?

• A. Frequent minor withdrawal symptoms only
• B. Prior withdrawal history, age, and comorbidities
• C. No identifiable risk factors
• D. Isolated alcohol use without history of withdrawal

Answer: (B)

Delirium tremens risk increases with factors that reflect greater physiologic vulnerability during withdrawal. The key predictors are a history of prior withdrawal, older age, and the presence of medical comorbidities. A history of previous withdrawal episodes indicates the brain has adapted to repeated periods of intoxication and abstinence, making a more severe withdrawal—and delirium tremens—more likely when abstinence occurs again. Older individuals have less physiologic reserve and are more likely to have supporting health issues such as liver disease, electrolyte disturbances, malnutrition, or infections, all of which can amplify withdrawal severity and precipitate delirium. Medical comorbidities in general—especially liver disease, renal dysfunction, electrolyte imbalances, infections, or nutritional deficiency—impair detoxification and brain function, further increasing the risk. Frequent minor withdrawal symptoms may occur, but they do not by themselves reliably predict progression to delirium tremens. Likewise, if there are no identifiable risk factors, delirium tremens is less likely, though it can still occur in rare cases.
