[Age patterns in the dynamics of unfavorably developing forms of schizophrenia in the light of late follow-ups in old age].

On the basis of study of 376 elderly patients it was established that the progression of the schizophrenic process, even in unfavorably developing forms (continuous-progressive, attacklike becoming continuous and attacklike with protracted attacks) in most of the cases is not unlimited. The greatest activity of the morbid process is seen in middle age and in the involutional period, while its alleviation (irrespective of age of the disease onset) coincides with senescence. These data may facilitate an establishment of a long-term prognosis and determine the correct therapeutic and social measures in relation to patients of old age.
