Abstract

As many as 38 patients with the bipolar and 70 patients with the monopolar types of affective psychosis manifesting at an age over 45 years were examined. A comparative age-associated examination of the given patients has demonstrated that the differences in the clinical characteristics and regularities of the mono- and bipolar disease forms are age-restricted and can be elucidated more frequently in the involutional period (from 45 to 59 years). In the senile age proper (after 60 years) there is a tendency towards approximation of both the types of late affective psychosis in terms of their main clinical parameters.
