Red flags
- Active suicidal intent or planning during stimulant crash, severe alcohol-related depression, or early withdrawal — same-day senior review, observation, and means restriction
- Alcohol or benzodiazepine withdrawal risk with autonomic instability, seizures, or confusion — medical detox and thiamine before pure psychiatric labelling
- New mania or mixed features with corticosteroids or other culprit medications on the drug chart — co-manage taper with the treating team
- Depression or anxiety persisting substantially beyond the expected intoxication/withdrawal window after confirmed abstinence — reclassify toward independent disorder and treat fully
- Chronic benzodiazepines layered onto dual alcohol/anxiety presentations — iatrogenic dependence risk
- Do not dismiss all affective symptoms in heavy drinkers as trivial, and do not start lifelong polypharmacy on day one of intoxication without a timeline
Meet the patient
A 47-year-old man is brought in by his wife. He has drunk heavily for three weeks after a job loss, and for the last week he has been unable to get out of bed, eating nothing, telling her he is worthless and the children are better off without him. His breath alcohol is positive tonight.[1][8]
The registrar writes depression, start SSRI. The examiner's question is the whole topic: is this an independent major depressive disorder that happens to drink, or an alcohol-induced depressive disorder — and what changes about tonight's plan depending on the answer?[1][4]
