[Principles of cognitive remediation in schizophrenia]

Cognitive remediation is an innovative psychosocial therapy which can provide a substantial benefit, especially for schizophrenic patients. As its name implies, the aim of cognitive remediation is to restore cognitive functions. Most cognitive domains (attention, memory and executive functions) are impaired in schizophrenia. Remediation therapy must be administered by an expert, and is based on cognitive training on the one hand, and on learning of cognitive strategies on the other hand. With these techniques the patient is better able to solve complex cognitive problems and to apply these new skills to everyday situations. Several techniques are available in France, using either computer-based or paper/pencil approaches. The programs are administered over several months, with one or more sessions per week. Cognitive remediation itself provides only a modest cognitive benefit, which must be enhanced by the adjunction of other therapies such as behavioral therapy, learning of social skills, or a vocational program during the first months of employment.
