Family history and deficit form in schizophrenia.
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.
