Resumen:
ABSTRACT ? Background and Objectives: Studies in patients with schizophrenia haveshown a decreased overall cognitive performance, and it was found that processing speedand working memory functions are affected. The aim of this study was to describe thegeneral cognitive performance of patients with chronic schizophrenia and analyze its relationshipwith the severity of psychotic symptoms.Methods: Forty-eight patients diagnosed with DSM IV-TR schizophrenia disorderwere examined for symptom improvement, measured by scales SAPS and SANS. Participantsalso completed the full scale WAIS-III.Results: The results show a generalized cognitive deficit, reflected in the low level of generalintelligence, as well as the different index that comprise the scale. The most compromisedindex was the processing speed. The correlations showed that the overall severity of negativesymptoms significantly affects cognitive functioning of chronic patients. The formal thoughtdisorder and alogia significantly correlated with almost all the WAIS-III measures.Conclusions: Multiple studies of specific cognitive domains in schizophrenia haveshown that deficits in processing speed are the core element of cognitive impairment inschizophrenia. We support the hypothesis about the slowing in cognitive processing affectboth the performance of the basic and more complex cognitive task.
