People suffering from psychosis, in particular from schizophrenia and bipolar disorder, but also from depression, present various disorders of cognitive functions, both in the context of neurocognition and of social cognition. These deficits have a significant negative impact on patient’s functioning in the real life and contrast the clinical remission and functional recovery of the patient. The evaluation of these deficits and their treatment are therefore an essential objective of an effective management of subjects with psychiatric disorders in the perspective of recovery and psychosocial reintegration.
