Criteria for Major Depressive Disorder
- Duration: ≥2 weeks, most of the day, nearly every day
- Organic causes must be excluded: not attributable to the abuse of psychoactive substances or to an organic mental disorder.
- ICD-11 criteria vs DSM-V criteria: While ICD-10 criteria recognizes loss of energy or fatigue as a major or key symptoms, DSM-V and ICD-11 doesn’t recognize it as a key symptom. Hence, DSM-V has only 2 key symptoms.
- “Loss of confidence or reduced self-esteem” is there in ICD-10/11 criteria (total 10 symptoms) but not there in DSM-V criteria (total 9 symptoms).
- Diagnosis by DSM-V and ICD-11: ≥5 symptoms with ≥1 of the 2 key symptoms – “S” or “I” symptoms from SIGECAPS or “D” or “P” symptoms from DEPRESSION mnemonic
- Diagnosis by ICD-10: ≥2 of the 3 key symptoms – “S”, “I” or “E” symptoms from SIGECAPS or “D”, “E” or “P” symptoms from DEPRESSION mnemonic + ≥2 of other symptoms
Grading of Depression
Unlike in the ICD-10, grading of depression into mild, moderate and severe is not based on the sum of the symptoms, but also takes into account their intensity and the degree of functional impairment in addition to the number of symptoms.
