Depression

The essential feature of Major Depressive Disorder is a clinical course that is characterized by one or more Major Depressive Episodes without a history of Manic, Mixed, or Hypomanic Episodes (Criteria A and C).  Episodes of Substance -Induced Mood Disorder (due to the direct physiological effects of a drug of abuse, a medication, or toxin exposure) or of Mood Disorder due to a General Medical Condition do not count toward a diagnosis of Major Depressive Disorder.  In addition, the episodes must not be better accounted for by Schizoaffective Disorder and are not superimposed on Schizophrenia, Schizophreniform Disorder, Delusional Disorder, or Psychotic Disorder Not Otherwise Specified (Criterion B).

 

The essential feature of a Major Depressive Episode is a period of at least 2 weeks during which there is either depressed mood or the loss of interest or pleasure in nearly all activities.  In children and adolescents, the mood may be irritable rather than sad.  The individual must also experience at least four additional symptoms drawn from a list that includes changes in appetite or weight, sleep, and psychomotor activity; decreased energy; feelings of worthlessness or guilt; difficulty thinking, concentrating, or making decisions; or recurrent thoughts of death or suicidal ideation, plans, or attempts.  To count toward a Major Depressive Episode, a symptom must either be newly present or must have clearly worsened compared with the person's pre-episode status.  The symptoms must persist for most of the day, nearly every day, for at least 2 consecutive weeks.  The episode must be accompanied by clinically significant distress or impairment in social, occupational, or other important areas of functioning.  For some individuals with milder episodes, functioning may appear to be normal, but requires markedly increased effort.
