title: Family history and deficit form in schizophrenia.
abstract: As no genetic study has been made in deficit patients, characterized by enduring and primary negative symptoms, the aim of the study was to test the involvement of a familial factor in deficit syndrome. The results in 71 schizophrenic patients showed less familial factors but a greater weight in heritage of schizophrenia in deficit than in nondeficit patients.
