title: Dysthymia and cyclothymia: historical origins and contemporary development.
abstract: The aim of this article is to review and put in their historical context today's data, methodologies and concepts concerning subaffective disorders. The historic roots of dysthymic and cyclothymic disorders--part of the subaffective spectrum--are essentially Greek, but the first use of the word 'dysthymia' in psychiatry was by C.F. Flemming in 1844. E. Hecker introduced the term 'cyclothymia' in 1877. K.L. Kahlbaum (1882) further developed the concepts of hyperthymia, cyclothymia and dysthymia--with possible subthreshold symptomatology--in 1882. After Kraepelin's rubric of 'manic-depressive insanity', the term 'dysthymia' was widely forgotten, and 'cyclothymia' became ill defined. Nowadays the latter term is used in three, partially contradictory, senses: (1) a synonym for bipolar disorder (K. Schneider), (2) a temperament (E. Kretschmer) and (3) a subaffective disorder (DSM-IV, ICD-10). A renaissance of subaffective disorders began with the development of DSM-III. Therapeutically important research has focused on dysthymic disorder and its relationship to major depressive disorder, while cyclothymic disorder is relatively neglected; nonetheless, operationalized as a subaffective dimension or temperament, cyclothymia appears to be a likely precursor or ingredient of the construct of bipolar II disorder.
