Data are presented on the 15-year natural course of schizophrenia and other nonaffective functional psychoses in a cohort of 82 first-contact cases from a circumscribed area in the Netherlands.
The subjects were suffering from functional psychosis with International Classification of Diseases-Ninth Revision (ICD-9) diagnoses 295,297, or 298.3-9 (broad definition of schizophrenia) on entry.
Standardized assessments of psychopathology, psychological impairments, negative symptomatology, social disability, and use of mental healthcare were used.
The study reveals a pattern of chronicity and relapses with a high risk of suicide :
Two-thirds of the subjects had at least one relapse and after each relapse 1 of 6 subjects did not remit from the episode ;
1 of 10 committed suicide ;
and 1 of 7 had at least one episode with affective psychotic symptoms that started on average 6 years after the onset of the schizophrenic disorder.
Diagnoses were reclassified in five patients, according to DSM-III-R criteria for a bipolar disorder.
The predictive power-in terms of time in psychosis and in partial or full remission-of demographic, illness, and treatment variables at onset of the illness was very limited.
Insidious onset and delays in mental health treatment are risk factors that predict a longer duration of first or subsequent episodes. (...)
