[The meaning of obsessive features of personality in the vulnerability and prognosis of schizophrenia].

In this study on schizophrenia, we raise the issue of the existing relation between negative symptoms (also called symptoms of deficiency) cognitive impairment attributed to the illness and personality features, in a population of chronically ill, long-term hospitalized men. We found obsessive personality features were present in the group of patients which presented fewer signs of deficiency and cognitive impairment. The presence of these features constitutes an important element in the evaluation of prognosis and vulnerability to suffer the illness.
