Insight cognitif et schizophrénie

International audienceLa schizophrénie est souvent associée à une méconnaissance du trouble sévère et persistante. Ce déficit d'insight est corrélé à l'hypofrontalité mais indépendant du pronostic de la maladie ou du quotient intellectuel. L'insight cognitif est défini comme la différence entre la capacité de réflexion sur soi et la certitude dans cette réflexion. Cette capacité est trouvée diminuée dans la schizophrénie mais augmentée en cas de dépression. Ainsi, la schizophrénie avec comorbidité dépressive est associée à un plus haut niveau d'insight. Les auteurs discutent que la prise de conscience de la maladie psychotique peut être vécue comme traumatique, constituant un facteur de risque de dépression et de passage à l'acte suicidaire

Erratum: The Relationship between Insight and Uncertainty in Obsessive-Compulsive Disorder

<i>Background:</i> The aim of this study was to investigate the relationship between the levels of insight and checking-related uncertainty in patients with obsessive-compulsive disorder (OCD). <i>Sampling and Methods:</i> Twenty OCD patients with checking compulsions and without current comorbidity were recruited. We used an experimental paradigm that gave subjects the opportunity to check during a decision-making task, thereby allowing for the calculation of a response time index (RTI) as the ‘uncertainty cost’ during decision-making. The level of insight was assessed with the Brown Assessment of Beliefs Scale (BABS). <i>Results:</i> Regression analyses indicated a significant positive correlation between RTI and BABS scores (r = 0.49). <i>Conclusions:</i> The level of insight is related to cognitive characteristics underlying OCD symptoms, in particular, checking-related uncertainty in checking OCD patients. <i>Study Limitations:</i> The absence of a comparison group and the low number of included patients are the main limitations of the present study
