An individual diagnosed with brief psychotic disorder needs to meet all of the following criteria:
- Presence of one (or more) of the following symptoms. At least one of these must be delusions, hallucinations, or disorganized speech:
- Delusions.
- Hallucinations.
- Disorganized speech (e.g., frequent derailment or incoherence).
- Grossly disorganized or catatonic behavior.
Note: Do not include a symptom if it is a culturally sanctioned response. - Duration of an episode of the disturbance is at least 1 day but less
than 1 month, with eventual full return to premorbid level of
functioning.
- The disturbance is not better explained by major depressive or
bipolar disorder with psychotic features or another psychotic disorder
such as schizophrenia or catatonia, and is not attributable to the
physiological effects of a substance (e.g., a drug of abuse, a
medication) or another medical condition.
- Specify if:
- With marked stressor(s) (brief reactive psychosis): If
symptoms occur in response to events that, singly or together, would be
markedly stressful to almost anyone in similar circumstances in the
individual's culture.
- Without marked stressor(s): If symptoms do not occur in
response to events that, singly or together, would be markedly stressful
to almost anyone in similar circumstances in the individual's culture.
- With postpartum onset: If onset is during pregnancy or within 4 weeks postpartum.
- Specify if:
- With catatonia: The clinical picture is dominated by three (or more) of the following symptoms:
- Stupor (i.e., no psychomotor activity; not actively relating to environment).
- Catalepsy (i.e., passive induction of a posture held against gravity).
- Waxy flexibility (i.e., slight, even resistance to positioning by examiner).
- Mutism (i.e., no, or very little, verbal response [exclude if known aphasia]).
- Negativism (i.e., opposition or no response to instructions or external stimuli).
- Posturing (i.e., spontaneous and active maintenance of a posture against gravity).
- Mannerism (i.e., odd, circumstantial caricature of normal actions).
- Stereotypy (i.e., repetitive, abnormally frequent, non-goal-directed movements).
- Agitation, not influenced by external stimuli.
- Grimacing.
- Echolalia (i.e., mimicking another's speech).
- Echopraxia (i.e., mimicking another's movements).
