A 3-year prospective follow-up investigation and a family study were carried out in patients fulfilling the diagnostic criteria for cycloid psychotic disorder proposed by Perris and Brockington in 1981. The results show that cycloid psychosis differs in several respects from schizoaffective disorders as defined by current diagnostic criteria used in the United States. Furthermore, they seem to suggest that most cases of cycloid psychosis are not variants of either schizophrenia or major affective disorders.
对符合1981年佩里斯和布罗金顿提出的环性心境障碍诊断标准的患者进行了一项为期3年的前瞻性随访调查和一项家族研究。结果表明，环性精神病在几个方面与美国现行诊断标准所定义的分裂情感性障碍有所不同。此外，这些结果似乎表明，大多数环性精神病病例既不是精神分裂症的变体，也不是重度情感障碍的变体。
