Schizophreniform disorder

Schizophreniform disorder is a mental disorder diagnosed when symptoms of schizophrenia are present for a significant portion of time (at least a month), but signs of disturbance are not present for the full six months required for the diagnosis of schizophrenia.

The symptoms of both disorders can include delusions, hallucinations, disorganized speech, disorganized or catatonic behavior, and social withdrawal. While impairment in social, occupational, or academic functioning is required for the diagnosis of schizophrenia, in schizophreniform disorder an individual's level of functioning may or may not be affected. While the onset of schizophrenia is often gradual over a number of months or years, the onset of schizophreniform disorder can be relatively rapid.

Like schizophrenia, schizophreniform disorder is often treated with antipsychotic medications, especially the atypicals, along with a variety of social supports (such as individual psychotherapy, family therapy, occupational therapy, etc.) designed to reduce the social and emotional impact of the illness. The prognosis varies depending upon the nature, severity, and duration of the symptoms, but about two-thirds of individuals diagnosed with schizophreniform disorder go on to develop schizophrenia.
