Schizoaffective Disorder
American Description
Diagnostic Criteria
An uninterrupted period of illness during which, at some time, there is either (1) a Major Depressive Episode, (2) a Manic Episode, or (3) a Mixed Episode concurrent with symptoms that meet (4) Criterion A for Schizophrenia.
Note: The Major Depressive Episode must include depressed mood.
(1) Criteria for Major Depressive Episode
Five (or more) of the following symptoms have been present during the same 2-week period and represent a change from previous functioning; at least one of the symptoms is either (1) depressed mood or (2) loss of interest or pleasure.
Note: Do not include symptoms that are clearly due to a general medical condition, or mood-incongruent delusions or hallucinations.
depressed mood most of the day, nearly every day, as indicated by either subjective report (e.g., feels sad or empty) or observation made by others (e.g., appears tearful). Note: In children and adolescents, can be irritable mood.
markedly diminished interest or pleasure in all, or almost all, activities most of the day, nearly every day (as indicated by either subjective account or observation made by others)
significant weight loss when not dieting or weight gain (e.g., a change of more than 5% of body weight in a month), or decrease or increase in appetite nearly every day. Note: In children, consider failure to make expected weight gains.
insomnia or hypersomnia nearly every day
psychomotor agitation or retardation nearly every day (observable by others, not merely subjective feelings of restlessness or being slowed down)
fatigue or loss of energy nearly every day
feelings of worthlessness or excessive or inappropriate guilt (which may be delusional) nearly every day (not merely self-reproach or guilt about being sick)
diminished ability to think or concentrate, or indecisiveness, nearly every day (either by subjective account or as observed by others)
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 committing suicide
The symptoms do not meet criteria for a Mixed Episode
The symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
The symptoms are not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition (e.g., hypothyroidism).
The symptoms are not better accounted for by Bereavement, i.e., after the loss of a loved one, the symptoms persist for longer than 2 months or are characterized by marked functional impairment, morbid preoccupation with worthlessness, suicidal ideation, psychotic symptoms, or psychomotor retardation.
(2) Criteria for Manic Episode
A distinct period of abnormally and persistently elevated, expansive, or irritable mood, lasting at least 1 week (or any duration if hospitalization is necessary).
During the period of mood disturbance, three (or more) of the following symptoms have persisted (four if the mood is only irritable) and have been present to a significant degree:
inflated self-esteem or grandiosity
decreased need for sleep (e.g., feels rested after only 3 hours of sleep)
more talkative than usual or pressure to keep talking
flight of ideas or subjective experience that thoughts are racing
distractibility (i.e., attention too easily drawn to unimportant or irrelevant external stimuli)
increase in goal-directed activity (either socially, at work or school, or sexually) or psychomotor agitation
excessive involvement in pleasurable activities that have a high potential for painful consequences (e.g., engaging in unrestrained buying sprees, sexual indiscretions, or foolish business investments)
The symptoms do not meet criteria for a Mixed Episode
The mood disturbance is sufficiently severe to cause marked impairment in occupational functioning or in usual social activities or relationships with others, or to necessitate hospitalization to prevent harm to self or others, or there are psychotic features.
The symptoms are not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication, or other treatment) or a general medical condition (e.g., hyperthyroidism).
(3) Criteria for Mixed Episode
The criteria are met both for a Manic Episode and for a Major Depressive Episode (except for duration) nearly every day during at least a 1-week period.
The mood disturbance is sufficiently severe to cause marked impairment in occupational functioning or in usual social activities or relationships with others, or to necessitate hospitalization to prevent harm to self or others, or there are psychotic features.
The symptoms are not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication, or other treatment) or a general medical condition (e.g., hyperthyroidism).
(4) Criterion A of Schizophrenia
Two (or more) of the following, each present for a significant portion of time during a 1-month period (or less if successfully treated):
delusions
hallucinations
disorganized speech (e.g., frequent derailment or incoherence)
grossly disorganized or catatonic behavior
negative symptoms, i.e., affective flattening, alogia, or avolition
Only one symptom is required if delusions are bizarre or hallucinations consist of a voice keeping up a running commentary on the person's behavior or thoughts, or two or more voices conversing with each other.
During the same period of illness, there have been delusions or hallucinations for at least 2 weeks in the absence of prominent mood symptoms.
Symptoms that meet criteria for a mood episode are present for a substantial portion of the total duration of the active and residual periods of the illness.
The disturbance is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition.
Specify type:
Bipolar Type: if the disturbance includes a Manic or a Mixed Episode (or a Manic or a Mixed Episode and Major Depressive Episodes)
Depressive Type: if the disturbance only includes Major Depressive Episodes
