Bipolar Disorder, Schizophrenia Clinical Trial
— TOM-iOfficial title:
Functional Magnetic Resonance Imaging Study: Theory of Mind Deficits in Schizophrenia and Bipolar Disorder
Theory of mind (TOM), a main component of social cognition processes, refers to the capacity to infer one's own and other person's mental states. Deficits in social cognition are found in patients with schizophrenia and bipolar disorder. The purpose of this study is to compare the neurofunctional profiles of schizophrenic patients, bipolar patients and healthy participants during the performance of a TOM task. Results may help to understand the neural bases of the impairments in social cognition in schizophrenia and bipolar disorder, which may in turn help to propose potential new psychosocial therapeutic approaches in these disorders.
