Abstract
A genetic family study of the classical schizophrenic subgroups (33 hebephrenics, 38 catatonics, 69 paranoid schizophrenics) demonstrated a tendency towards differences in the global morbidity risk of schizophrenia (greatest in the relatives of catatonics) and a tendency towards a predominance of homotypical secondary cases. However, as these results are statistically not significant, they cannot be used as arguments in discussing the genetic separation of schizophrenic subtypes.
