Schizophrenia is an invalidating psychiatric illness with a strong genetic component
characterized by abnormal processing of emotional information. This alteration in emotion
processing has been described in acute as well as in remission phases of the illness. It
has also been found in healthy relatives of patients with schizophrenia and in subjects
at high risk of psychosis. Thus, alterations in emotional information processing are not
only linked to the prognosis but can also be considered as a marker of vulnerability of
schizophrenia. In addition, schizophrenia patients differ from healthy controls in neural
activity in brain regions implicated in emotions processing. However, interpretation of
findings in patients is limited by confounding factors, such as antipsychotic treatments
or alterations due to the course of illness. Also, there is no data concerning genetic
factors (polymorphisms or gene expression) underlying these patterns of cerebral
activation in emotion information processing.
So, the main objective of this study is to compare the cerebral activity of schizophrenia
patients to that of healthy siblings and healthy controls in an emotional processing
task.
