Seventy-three patients with the features of 'cycloid psychosis', adopted from Perris and Leonhard, were identified from case records. Information concerning background, presenting illness and follow-up was compared with that from the case-records of patients with schizophrenic, affective and schizoaffective psychoses. The characteristic features of 'cycloid psychosis' were a female predominance and a remittent course. The 'cycloid' group resembled the conventional groups in some respects, but differences from schizophrenic, affective and, to a lesser extent, schizoaffective groups were also striking. The factors which might account for the apparent independence of the 'cycloid' group from other diagnostic categories are discussed.
从病例记录中识别出73例具有“环性精神病”特征的患者，这些特征参照了佩里斯（Perris）和莱昂哈德（Leonhard）的描述。将这些患者的背景、现病史及随访信息与精神分裂症、情感性精神病和分裂情感性精神病患者的病例记录信息进行了比较。“环性精神病”的特征为女性居多且病程呈缓解性。“环性”组在某些方面与传统组相似，但与精神分裂症组、情感性精神病组以及程度较轻的分裂情感性精神病组也存在显著差异。文中讨论了可能导致“环性”组明显独立于其他诊断类别的因素。
