Depression, Adolescent
Basics
Description
- DSM-5 depressive disorders include major depressive disorder (MDD), disruptive mood dysregulation disorder (DMDD), persistent depressive disorder (PDD), premenstrual dysphoric disorder, substance/medication-induced depressive disorder, and other nonspecific depression. This chapter focuses on MDD as it relates to the adolescent patient.
- MDD is a primary mood disorder characterized by sadness and/or irritable mood with impairment of functioning; abnormal psychological development; and a loss of self-worth, energy, and interest in typically pleasurable activities.
- DMDD is characterized by having severe, recurrent outbursts along with persistent irritability and anger.
- PDD is characterized by a depressed mood for most days lasting at least 1 year in a child/adolescent.
- Adolescents with depression are likely to suffer broad functional impairment across social, academic, family, and occupational domains, along with a high incidence of relapse and a high risk for substance abuse and other psychiatric comorbidity.
Epidemiology

Prevalence

- DMDD: 2–5%; more prominent in males (2)
Etiology and Pathophysiology
- Unclear; low levels of neurotransmitters (serotonin, norepinephrine); decreased functioning of the dopamine system also contributes.
- External factors may affect neurotransmitters independently.
- Hormonal changes during puberty
