Heredity in Catatonic Schizophrenia

The study presents data about heredity of catatonic schizophrenia in comparison with all other types of schizophrenia. The sample consisted of 402 schizophrenics, who were followed up from 1972 until 1990/91. It was found that ICD diagnosis of catatonic type of schizophrenia was made in 59 (14.7%) cases, once or several times. Among these patients there were 28 males and 31 females. These 59 patients with noted catatonic symptoms, at least once in their life, were compared with the remaining 343 patients, who never had catatonic symptoms. In 44.1% of catatonics positive psychiatric heredity was found and that was significantly greater (p<0.001) than in other schizophrenics (20.1%). This study confirms a great significance of the genetic predisposition for developing schizophrenia, and it supports the thesis that the catatonic type is relatively mostly genetically determined.
