title: [The late-onset rapid cycling affective disorder].
abstract: 166 depressive outpatients in Kurume University Hospital who were over sixty years old in 1993 were analyzed. Only 3 cases (1.8%) of the depressives were satisfied with the Dunner's criteria, which repeats affective episodes at least more than 4 times a year. Two of eight cases which were diagnosed the manic depressive illness satisfied the criteria. Most of the depressives were stable states and the depressive episodes did not change through one year. We presented a female case (aged 71), satisfying the DSM-3-R criteria for bipolar disorder. In this case, we monitored her polysomnography, and rectal temperature. Consequently this case showed remarkable changes in these parameters under manic, depressive and remissional phase, respectively. We conclude there are a few cases of the rapid cycling affective disorder over 60 years.
