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 \u2018cycloid psychosis\u2019 were a female predominance and a remittent course. The \u2018cycloid\u2019 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 \u2018cycloid\u2019 group from other diagnostic categories are discussed.<\/jats:p>","DOI":"10.1017\/s0033291700018845","type":"journal-article","created":{"date-parts":[[2009,7,9]],"date-time":"2009-07-09T15:53:11Z","timestamp":1247154791000},"page":"637-648","source":"Crossref","is-referenced-by-count":67,"title":["Cycloid psychosis: an investigation of the diagnostic concept"],"prefix":"10.1017","volume":"8","author":[{"given":"J.
