[The relationship between cognition and functional outcome in schizophrenia].

Schizophrenia is associated with poor functional outcome, which has been shown to be associated with cognitive impairment, a core feature of the illness. The aim of the present study is to provide an overview of measurements of cognitive deficit and everyday functioning in schizophrenia. The authors demonstrate that cognitive impairment is a predictor of subsequent functional outcome measures by reviewing the relevant cross-sectional and longitudinal studies. Furthermore, models proposing intermediate variables that may provide a link between cognition and functional outcome are discussed. Such mediator variables are social cognition and functional capacity. Future avenues of research on cognition and functional outcome in schizophrenia are outlined, as there is considerable interest in finding treatments to improve cognition in schizophrenia. Improvements in cognitive deficits are expected to lead to benefits in the everyday functioning of the patients.
