背景关于摆线精神病的起源，有三种假说：（1）它们是一个独立的疾病分类学实体;（2）它们是情感障碍的非典型病例;（3）它们是一组异质性障碍。本研究通过试图描绘不同的情感和非情感subgroup.MethodsIn 60例从经典的研究周期性精神病的佩里斯（1974），潜在的类分析被用来描绘subgroup.ResultsTwo类确定在分析：一种以情感症状和情感障碍家族史的融合为特征，另一种以此类特征的相对缺乏为特征。精神病至少可分为两类，可根据症状和家族史加以区分。
BackgroundThree hypotheses have been proposed in regard to the origin of cycloid psychoses: (1) they are an independent nosological entity; (2) they are atypical cases of affective disorders; and (3) they are a heterogeneous group of disorders. This study examined the heterogeneity hypothesis by attempting to delineate distinct affective and non-affective subgroups.MethodsIn 60 cases drawn from a classic study of cycloid psychoses by Perris (1974), latent class analysis was used to delineate subgroups.ResultsTwo classes were identified in the analysis: one characterized by the convergence of affective symptoms and family history of affective disorders and the other by the relative paucity of such features.ConclusionsCycloid psychoses are composed of at least two subgroups, distinguishable on the basis of symptoms and family history.
