Abstract

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. The importance of mental health treatment in regard to outcome is probably subject to change because an early warning and intervention strategy could prevent further damage and deterioration. Our data support the need for an adequate relapse prevention program as a priority for our mental health services.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
