311 Depressive Disorder Not Otherwise Specified

The Depressive Disorder Not Otherwise Specified category includes disorders with depressive features that do not meet the criteria for Major Depressive Disorder, Dysthymic Disorder, Adjustment Disorder With Depressed Mood (see p. 679), or Adjustment Disorder With Mixed Anxiety and Depressed Mood (see p. 680). Sometimes depressive symptoms can present as part of an Anxiety Disorder Not Otherwise Specified (see p. 484). Examples of Depressive Disorder Not Otherwise Specified include

  1. Premenstrual dysphoric disorder: in most menstrual cycles during the past year, symptoms (e.g., markedly depressed mood, marked anxiety, marked affective lability, decreased interest in activities) regularly occurred during the last week of the luteal phase (and remitted within a few days of the onset of menses). These symptoms must be severe enough to markedly interfere with work, school, or usual activities and be entirely absent for at least 1 week postmenses (see p. 771 for suggested research criteria).
  2. Minor depressive disorder: episodes of at least 2 weeks of depressive symptoms but with fewer than the five items required for Major Depressive Disorder (see p. 775 for suggested research criteria).
  3. Recurrent brief depressive disorder: depressive episodes lasting from 2 days up to 2 weeks, occurring at least once a month for 12 months (not associated with the menstrual cycle) (see p. 778 for suggested research criteria).
  4. Postpsychotic depressive disorder of Schizophrenia: a Major Depressive Episode that occurs during the residual phase of Schizophrenia (see p. 767 for suggested research criteria).
  5. A Major Depressive Episode superimposed on Delusional Disorder, Psychotic Disorder Not Otherwise Specified, or the active phase of Schizophrenia.
  6. Situations in which the clinician has concluded that a depressive disorder is present but is unable to determine whether it is primary, due to a general medical condition, or substance induced.
