title: [Social cognitive differences in first-degree relatives of patients with schizophrenia. A systematic review].
abstract: The impairment of social functioning and difficulties in social integration are frequently found in patients with schizophrenia, and may affect the quality of life, thus revealing the underlying mechanisms of these differences appear to be of high importance. The impairment of social functioning has been reported in first-degree relatives of schizophrenia patients and individuals at ultra-high risk for psychosis. Two meta-analyses and 15 studies were reviewed, in which various ToM tests were performed involving first-degree relatives of patients with schizophrenia,with diverse findings, both positive and negative results have been found, and in addition other cognitive deficits were reported in some cases. In the background of different findings methodological differences can be presumed. Overall the social cognitive functions of first-degree relatives were found affected, which suggests the role of social cognition as endophenotypic marker of schizophrenia.
