Delirium tremens is a withdrawal syndrome most commonly associated with which substance?

• A. Alcohol
• B. Narcotics
• C. Inhalants
• D. Stimulants

Answer: (A)

Delirium tremens reflects a severe alcohol withdrawal reaction. When someone drinks chronically, their brain adapts to the depressant effects of alcohol. After stopping suddenly, those adaptive changes produce a rebound hyperactivity of the nervous system, leading to marked agitation, tremors, confusion, perceptual changes, and autonomic instability. This pattern most commonly appears about 48 to 72 hours after the last drink and can last several days. Because this is the classic, life-threatening form of withdrawal associated with stopping alcohol, it’s most strongly linked to alcohol use. In clinical practice, recognizing this pattern prompts urgent management with supportive care and medications like benzodiazepines to control symptoms and prevent seizures, along with thiamine supplementation to prevent deficiency-related complications.
