symptoms; or (2) if mood episodes have occurred during active-phase
symptoms, their total duration has been brief relative to the duration
of the active and residual periods.
C. 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.

stable and fulfill the criteria for schizophrenia but have lasted
for less than 1 month. Some degree of emotional variability or instability
may be present, but not to the extent described in acute polymorphic
psychotic disorder.
Diagnostic
Guidelines
For a definite diagnosis:
(a)
the onset of psychotic symptoms must be acute (2 weeks or less from
a nonpsychotic to a clearly psychotic state);
(b) symptoms that fulfill the criteria for schizophrenia must have
been present for the majority of the time since the establishment
of an obviously psychotic clinical picture;
(c) the criteria for acute polymorphic psychotic disorder are not
fulfilled.
If
the schizophrenic symptoms last for more than 1 month, the diagnosis
should be changed to schizophrenia.
Includes:
* acute (undifferentiated) schizophrenia
* brief schizophreniform disorder
* brief schizophreniform psychosis
* oneirophrenia
* schizophrenic reaction
