Red flags
- Severe melancholia with food or fluid refusal, catatonia, or psychosis — escalate; do not titrate community SSRI indefinitely
- Active suicidal ideation, plan or attempt — specifier label never reduces intensity of risk response
- Hypomania or mania after antidepressant or activation — re-screen bipolar spectrum, especially in reverse-vegetative atypical presentations
- MAOI plus serotonergic drug or incomplete fluoxetine washout — serotonin toxicity risk
- Tyramine-rich diet breach on irreversible MAOI — treat as possible hypertensive crisis
- Assuming atypical features equal mild illness or low suicide risk
Meet the patients — both of them
Bed 4. A 68-year-old man, three weeks in. He wakes at 3am, is worst before breakfast, has lost 7 kg, sits without moving, and tells you flatly that he has ruined his family. His daughter visits with good news about a grandchild. Nothing happens to his face.[7][9]
Clinic, 2pm. A 26-year-old woman, depressed for eight months. She sleeps eleven hours, eats constantly, describes her legs as "filled with wet sand," and has left two jobs after being criticised. A friend texts something kind and she brightens for an hour — then it closes over again.[4][6]
Same DSM chapter. Opposite illnesses. One question separates them, and one answer changes the treatment plan: does good news get through?[1][4][7]
