| Outline of Final Research Achievements |
Cognitive impairment is one of the core symptoms of schizophrenia that significantly influences patients’ social function. Cognitive remediation, of which a main component is repetitive cognitive training, is a promising approach for this impairment. In this study, we used brain training games as a cognitive training program. In addition to measuring the change in cognitive performance from pre- to post-intervention, we investigated the influence of cognitive training on gray matter structures. An 8-week intervention revealed that cognitive training using brain training games significantly improved patients’ processing speed and executive function compared to visuospatial puzzle games. In addition, the improved cognitive performance was accompanied by regional gray matter volume changes. These findings suggest that cognitive training not only influences the performance on cognitive measures, but also patients’ neural structures.
