Meeting the 5-symptom major depressive episode threshold for at least 2 weeks separates MDD from adjustment disorder.
Side by side
Emotional or behavioral symptoms begin within 3 months of an identifiable stressor and do not meet full major depressive episode criteria.
At least 5 depressive symptoms including depressed mood or anhedonia for 2 weeks with functional impairment indicates major depressive disorder.
Stress-linked maladaptive coping produces distress that is disproportionate to the trigger but typically time-limited.
Major depressive disorder reflects persistent mood-circuit dysregulation with biologic and psychosocial contributors independent of a single stressor.
Diagnosis is clinical; symptoms start within 3 months of stressor and resolve within 6 months after stressor or consequences end, without persistent neurovegetative syndrome meeting MDD threshold.
MDD requires at least 5 SIGECAPS symptoms for at least 14 days, and severe episodes may include suicidal ideation, psychomotor changes, or psychotic features requiring urgent intervention.
The trap
A clear stressor can distract clinicians from counting symptoms, leading to underdiagnosed MDD. The resolving clue is syndromic burden and sustained impairment, not merely trigger presence.
The repair move
Next best step: if full MDD criteria with functional decline are present, initiate evidence-based treatment such as SSRI therapy with close follow-up and suicide risk monitoring, plus psychotherapy. If symptoms are subthreshold and clearly stressor-linked, prioritize brief psychotherapy and stressor-focused support before pharmacotherapy.

CoreA 34-year-old man reports low mood after divorce for 1 month but has normal sleep, appetite, concentration, and energy, and continues working full time. He has no suicidal ideation. What is the most likely diagnosis?
Show answer and explanation
Answer: A. Adjustment disorder. Recent stressor-linked distress without full major depressive symptom burden is most consistent with adjustment disorder.
Why the other choices are tempting
- B. MDD requires at least 5 symptoms for at least 2 weeks with significant impairment.
- C. Persistent depressive disorder requires chronic depressive symptoms for at least 2 years.
- D. No hypomanic episodes are described to support bipolar II disorder.
- E. Cyclothymia requires prolonged fluctuating hypomanic and depressive symptoms, not isolated stress response.
