[Biological rhythms in psychopathology (biological patterns in psychiatry)]

On the basis of a clinical follow-up study of regularities of 486 cycles (phases and intervals) in the course of a disease in 80 endogenous and exogenous nosological patients the author established the principal resemblance in the rhythm of cycles and the coincidence of the curves in the regularity of attacks with a sharp displacement of the peaks of regularities in IV-VI and IX-X months (for epilepsy in VIII and XII months). The author tries to explain the latter fact by the influences of geophysical factors on synchronization, in periods of vernal and autumnal equinox, of the processes of metabolism and the reactivity of separate neuronal structures and endocrine structures.
