简要总结
Disorders of social cognition, and empathy more specifically, are at the heart of schizophrenic pathology in that they are strongly linked to the social handicap of patients. It is therefore necessary to refine our knowledge of the cognitive and affective processes behind this empathic disorder and to identify objective and easily measurable markers (related to brain functioning collected by electroencephalography) of these processes with the subsequent aim of improving their management. It is also relevant to question the trait/status nature of these empathic disorders by studying these markers in individuals presenting more or less marked schizotypic traits and therefore more or less at risk of developing schizophrenia. Studying the possibility that empathy disorders may be part of the factors of developmental vulnerability for schizophrenia and identifying objective markers of this vulnerability could allow, in case of development of the pathology, a more rapid diagnosis and a more effective management.
