Kraepelin indicated the frequency of these various types (depression alone 48\u00b79 per cent, mania alone 16 6 per cent, circular 34\u00b75 per cent), but also emphasized how difficult it is to predict the precise course of the disease in any individual patient. He stated: \u2018we cannot speak of even an approximate regularity in the course of the disease\u2019, and \u2018the kind and direction of the attack and the intervals do not by any means remain the same in the individual case\u2019 (Kraepelin, 1921).<\/jats:p>","DOI":"10.1192\/bjp.120.558.537","type":"journal-article","created":{"date-parts":[[2008,8,12]],"date-time":"2008-08-12T22:35:43Z","timestamp":1218580543000},"page":"537-539","source":"Crossref","is-referenced-by-count":22,"title":["The Incidence of Depressive Symptoms During Recovery from Hypomania"],"prefix":"10.1192","volume":"120","author":[{"given":"H.
