RESUMO
Cognitive deficits in patients with schizophrenia constitute a limiting factor to the chances of rehabilitation of daily living abilities, like personal and relational autonomy and working ability. Cognitive Remediation Therapy (CRT) is a rehabilitative technique that aims at the recovery of single cognitive functions through the execution of massive exercises of impaired cognitive domains. This study aims to establish if the results achieved through an intensive deficit-specific neurocognitive treatment of three months duration, were maintained over time. The sample consists in 100 patients diagnosed with schizophrenia according to the criteria of DSM IV. Patients were assessed on cognitive and daily functioning at baseline, after 3 months of either CRT or placebo training added to their standard rehabilitation treatment, at 6 month and 12-month follow-up. Results showed significant changes that were maintained at follow-up for executive function, attention and psychomotor coordination. Moreover the significant improvement in daily functioning was maintained at 6 and 12-month follow-up. In conclusion improvements in cognitive functions and daily functioning achieved through the association of CRT and standard rehabilitation treatment persist over time after the conclusion of the training period.

"Theory of mind" (ToM) is the ability to judge the mental states of the self and others. It is currently considered as a part of the broader concept of social cognition, known to influence the social behaviour of patients affected by schizophrenia. Recently it has been hypothesized that the impairment of ToM is a trait that can be detected both in patients with schizophrenia and in non-psychotic relatives of patients, but it still not clear what the contribution of the familial patterns of cognitive impairment is. The aim of this study is to assess parental impairments of ToM performance considering the effects of the neurocognitive abilities known to be impaired in their first-degree relatives and to influence ToM in schizophrenic patients. Patients, their parents and control trios were assessed with the Wisconsin Card Sorting Test (WCST), the Symbol Coding Task and the ToM Picture Sequencing Task. The ANCOVA analysis on 47 trios including a schizophrenic offspring and 47 healthy trios showed a statistically significant poorer performance of patients and their parents in comparison to control trios at Symbol Coding Task and ToM task. Moreover a regression analysis showed that the neuropsychological abilities tested were significant predictors of ToM performance only in patients. Results confirm a ToM impairment among parents of patients with schizophrenia that is not directly correlated to other aspects of neurocognitive functioning.
