ICD-10 criteria vs DSM-V criteria for Depression
While ICD-1o criteria recognizes loss of energy or fatigue as a major or key symptoms, DSM-V doesn’t recognize it as a key symptom. Hence, DSM-V has only 2 key symptoms.
“Loss of confidence or reduced self-esteem” is not there in DSM-V criteria.
For diagnosis of Major Depressive Episode by DSM-V any 5 of the symptoms must be present with atleast 1 of the 2 key symptoms in same 2 week period (as in ICD-10).
