Diagnostic criteria for Major Depressive Episode


Note.' A "Major Depressive Syndrome" is defined as criterion A below.

A. At least five of the following symptoms have been present dunng the same two-week period and represent a change from previous functioning; as least one of the symptoms is either (1) depressed mood, or (2) loss of interest or pleasure. (Do not Include symptoms that are clearly due to a physicaJ condi-tion, mood-incongruent delusions or hallucinations, incoherence. or marked loosening of associations.)

(1) depressed mood (or can be irritable mood in children and adolescents) most of the day, nearly every day, as indicated either by subjective ac-count or observation by others
(2) markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day (as indicated either by subjective ac-count or observation by others of apathy most of the time)
(3) significant weight loss or weight gain when not dieting (e.g., more than 5o~ of body weight in a month), or decrease or increase in appetite nearly every day (in children, consider failure to make expected weight gains)
(4) insomnia or, hypersomnia nearly every day
(5) psychomotor agitation or retardation nearly every day (observable by others, not merely subjective feelings of restlessness or being slowed down)
(6) fatigue or loss of energy nearly every day
(7) feelings of worthlessness or excessive or inappropriate guilt (which may be delusional) nearly every day (not merely self-reproach or guilt about being sick)
(8) diminished ability to think or concentrate, or indecisiveness, nearly every day (either by subjective account or as observed by others)
(9) recurrent thoughts of death (not just fear of dying), recurrent suicidal ideation without a specific plan, or a suicide attempt or a specific plan for committin2 suicide

B.
(1) It cannot be established that an organic factor initiated and maintained the disturbance
(2) The disturbance is not a normal reaction to the death of a loved one (Uncomplicated Bereavement)

Note: Morbid preoccupation with worthlessness, suicidal ideation, marked functional impairment or psychomotor retardation, or prolonged duration suggest bereavement complicated by Major Depression.

C. At no time during the disturbance have there been delusions or hallucinations for as long as two weeks in the absence of prominent mood symptoms (i.e., before the mood symptoms developed or after they have remitted).

D. Not superimposed on Schizophrenia. Schizophreniform Disorder, Delusional Disorder, or Psychotic Disorder NOS.
 

Specify chronic if current episode has lasted two consecutive years without a period of two months or longer during which there were no significant depressive symptoms.

Specify if current episode is Melancholic Type.


Diagnostic Criteria for Melancholic Type


The presence of at least five of the following:
(1) loss of interest or pleasure in all, or almost all, activities
(2) lack of reactivity to usually pleasurable stimuli (does not feel much better, even temporarily, when something good happens)
(3) depression regularly worse in the morning
(4) early morning awakening (at least two hours before usual time of awakening)
(5) psychomotor retardation or agitation (not merely subjective complaints)
(6) significant anorexia or weight loss (e.g., more than 5% of body weight in a month)
(7) no significant personality disturbance before first Major Depressive Epi-sode
(8) one or more previous Major Depressive Episodes followed by complete or nearly complete. recovery
 (9)  previous good response to specific and adequate somatic antidepressant therapy . e.g. tricyclics, ECT. MAOI, lithium
 

Diagnostic Criteria for Seasonal Pattern

 

 

A. There has been a regular temporal relationship between the onset of an episode of Bipolar Disorder (including Bipolar Disorder NOS) or Recurrent Major Depression (including Depressive Disorder NOS) and a particular 60-day period of the year (e.g., regular appearance of depression between the beginning of October and the end of November).

Note: Do not include cases in which there is an obvious effect of seasonally related psychosocial stressors, e.g., regularly being unemployed every winter.

B. Full remissions (or a change from depression to mania or hypomania) also occurred within a particular 60-day period of the year (e.g., depression disap-pears from mid-February to mid-April).

C. There have been at least three episodes of mood disturbance in three sepa-rate years that demonstrated the temporal seasonal relationship defined in A and B; at least two of the years were consecutive.

D. Seasonal episodes of mood disturbance, as described above, outnumbered any nonseasonal episodes of such disturbance that may have occurred by more than three to one.
 

Diagnostic Criteria for Dysthymia


A. Depressed mood (or can be irritable mood in children and adolescents) for most of the day, more days than not, as indicated either by subjective account or observation by others, for at least two years (one year for children and adolescents)

B. Presence, while depressed, of at least two of the following:

(1) poor appetite or overeating
(2) insomnia or Hypersomnia
(3) low energy or fatigue
(4) low self-esteem
(5) poor concentration or difficulty making decisions
(6) feelings of hopelessness

C. During a two-year period (one-year for children and adolescents) of the disturbance, never without the symptoms in A for more than two months at a time.
D. No evidence of an unequivocal Major Depressive Episode during the first two years (one year for children and adolescents) of the disturbance.
Note: There may have been a previous Major Depressive Episode, provided there was a full remission (no significant signs or symptoms for six months) before development of the Dysthymia. In addition, after these two years (one year in children or adolescents) of Dysthymia, there may be superimposed episodes of Major Depression, in which case both diagnoses are given.

E. Has never had a Manic Episode (p.217) or an unequivocal Hypomanic Epi-sode (see p.217).

F. Not superimposed on a chronic psychotic disorder, such as Schizophrenia or Delusional Disorder.

G. It cannot be established that an organic factor initiated and maintained the disturbance, e.g., prolonged administration of an antihypertensive medica-tion.
 

Diagnostic Criteria for Cyclothymia


A. For at least two years (one year for children and adolescents), presence of numerous Hypomanic Episodes (all of the criteria for a Manic Episode, p.217, except criterion C that indicates marked impairment) and numerous periods with depressed mood or loss of interest or pleasure that did not meet criterion A of Major Depressive Episode.

B During a two-year period (one year in children and adolescents) of the distur-bance, never without hypomanic or depressive symptoms for more than two months at a time.

C. No clear evidence of a Major Depressive Episode or Manic Episode during the first two years of the disturbance (or one year in children and adolescents).

Note: After this minimum period of Cyclothymia1 there may be superimposed
Manic or Major Depressive Episodes, in which case the additional diagnosis of
Bipolar Disorder or Bipolar Disorder NOS should be given.

D. Not superimposed on a chronic psychotic disorder, such as Schizophrenia or Delusional Disorder.

E it cannot be established that an organic factor initiated and maintained the disturbance, e.g., repeated intoxication from drugs or alcohol.
 

Diagnostic Criteria for Manic Episode

Note: A "Manic Syndrome" is defined as inc4uding criteria A, B, and C below. A "Hypomanic Syndrome" is defined as including criteria A and B, but not C1 i.e., no marked impairment.

A. A distinct period of abnormally and persistently elevated, expansive, or irrita-ble mood.

B. During the period of mood disturbance, at least three of the following symp-toms have persisted (four if the mood is only irritable I and have been present to a significant degree:

(1) inflated self-esteem or grandiosity
(2) decreased need for sleep, e.g., feels rested after only three hours of sleep
(3) more talkative than usual or pressure to keep talking
(4) flight of ideas or subjective experience that thoughts are racing
(5) distractibility, i.e., attention too easily drawn to unimportant or irrelevant external stimuli
(6) increase in goal-directed activity (either socially, at work or school, or sexually) or psychomotor agitation
(7) excessive involvement in pleasurable activities which have a high poten-tial for painful consequences, e.g., the person engages in unrestrained buying sprees. sexual indiscretions, or foolish business investments
C. Mood disturbance sufficiently severe to cause marked impairment in occupa-tional functioning or in usual social activities or relationships with others, or to necessitate hospitalization to prevent harm to self or others.

D. At no time during the disturbance have there been delusions or hallucinations for as long as two weeks in the absence of prominent mood symptoms (i.e., before the mood symptoms developed or after they ha\'e remitted).

E. Not superimposed on Schizophrenia, Schizophreniform Disorder, Delusional Disorder, or Psychotic Disorder NOS.

F. lt cannot be established that an organic factor initiated and maintained the disturbance. Note: Somatic antidepressant treatment (e.g., drugs, ECTI that apparently precipitates a mood disturbance should not be considered an etiologic organic factor.
 

Diagnostic Criteria for Major Depressive Episode
