Signs and symptoms
MDD may be present when following signs and symptoms cluster together and persist for 2 weeks or more:
- persistent sadness
- loss of self-worth
- loss of interest in usual activities (like sports)
- social isolation
- decline in school work
- sleep and appetite disturbances
- nonspecific pain
A government-appointed medical panel recently recommended routine, yearly screening on all American teenagers for depression, even if they don't show symptoms. Studies show that your child's pediatrician can accurately diagnose MDD through questionnaires such as the Patient Health Questionnaire for Adolescents or the Beck Depression Inventory - Primary Care Version.
The recommendations by the United States Preventive Services Task Force appear in the April 2009 issue of the journal Pediatrics.
