This question involves understanding the possibilities associated with sudden alcohol withdrawal symptoms. The case describes a 50-year-old male who ceased alcohol consumption abruptly for 3 days, presenting with symptoms like agitation, altered sensorium, paranoid delusions, and hallucinations. These are classic manifestations to evaluate.
Here's a breakdown of the options:
- Wernicke's Encephalopathy: A result of thiamine (vitamin B1) deficiency, it's primarily associated with confusion, ophthalmoplegia, and ataxia, not paranoia or hallucinations.
- Korsakoff's psychosis: Generally follows Wernicke's, leading to memory disturbances and confabulation, lacking acute agitation and hallucinations.
- Hangover: Involves headache, nausea, and fatigue after alcohol consumption, not associated with serious psychiatric symptoms like hallucinations.
- Delirium Tremens: Occurs 48-72 hours after cessation in chronic users. Symptoms include severe agitation, confusion, hallucinations, and autonomic instability.
Based on the timing and severe neuropsychiatric symptoms, the most likely diagnosis is Delirium Tremens.
