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.
一项针对典型精神分裂症亚组(33例青春型精神分裂症患者、38例紧张型精神分裂症患者、69例偏执型精神分裂症患者)的遗传家系研究表明,精神分裂症总体发病风险存在差异趋势(在紧张型精神分裂症患者的亲属中最高),且存在同型继发性病例占主导的趋势。然而,由于这些结果在统计学上不显著,因此不能作为讨论精神分裂症亚型遗传分离的依据。
