In this paper results of a prospective follow-up study from 1959 to 1975 are presented. 159 unipolar depressive and 95 bipolar manic-depressive patients were subdivided into: --early onset patients (EO) less than 40 years, and--late onset patients (LO): greater than 40 years. These two groups are compared with each other. The common features predominate: they do not differ in the sex ratio, and the periodicity of the disorder. However, they differ in the length of episode of unipolar depression, recovery rate, and chronification.
