Impact des déficits cognitifs dans les activités de la vie quotidienne des personnes souffrant de schizophrénie

Abstract: It is now well-recognized that cognitive dysfonctions contribute to a decisive way to the difficulties of the everyday, social and professional life of the people with schizophrenia. The cognitive variables would explain between 16 and 30% of the variance in the functional status when assessed one to three and a half years later. However, the specificity of the complex relationships between the cognitive domains and the functional variables still remains to be identified. To this end, it is necessary to carry out studies by respecting various principles: selecting not multi-determined cognitive tasks; investigating specific daily-life tasks (e.g. shopping, choosing a menu, preparing a meal), in particular by an observation in real situation in order to identify the problematic components; this has to be made by determining a priori hypotheses regarding the cognitive nature of the difficulties; taking into account the heterogeneity of the cognitive deficits and the functional difficulties of people with schizophrenia. It also remains to investigate the presence of mediator variables of the relationships, such as the potential of learning, the social cognition, the metacognitive processes and the intrinsic motivation. Besides, other personal or environmental factors can also play a role in the functional status, as for example, the negative symptoms, the awareness that has the person of his(her) state and its consequences, or the critical attitude of relatives towards the person with schizophrenia.
