- W2246768150 abstract "The duration of untreated psychosis (DUP) and its association with the course of illness in schizophrenia has been widely addressed, but the conclusions still remain essentially unclear. The studies with unselected samples and longitudinal data are few and needed. The aim of this dissertation was to study DUP and the long-term course of illness in schizophrenia in a metaanalysis and in the Northern Finland 1966 Birth Cohort (NFBC 1966). A meta-analysis of 31 original studies on the long-term association between DUP and clinical and social outcomes showed that long DUP had a small but statistically significant association with poor symptomatic, social, and global outcomes. However, there was no significant correlation between DUP and use of treatment, employment, and quality of life. In the NFBC 1966, the associations between DUP and the outcomes (n=89) were assessed with several measurements of mental and psychical state, treatment factors, education, and ability to work. In the short-term outcome, long DUP was associated with longer first hospitalization and increased risk of re-hospitalization. In the long-term, long DUP was associated only with a decreased rate of disability pension. When the association between DUP and brain structures using magnetic resonance imaging (MRI) was analyzed (n=46), long DUP correlated with decreased gray-matter density in the right hippocampus. DUP may be a modest marker of a more severe clinical phenotype regarding early outcome, but in the NFBC 1966, longer DUP seems to associate with better clinical and occupational outcomes. The relatively modest effect of DUP on outcomes indicates that shortening DUP may have positive effects on the long-term clinical course. However, it is unlikely that early intervention alone could significantly improve the overall long-term outcome of schizophrenia. Early detection of psychosis is one of the possibilities to achieve the improvement, especially in the short-term outcome of schizophrenia." @default.
