[Development of circularity as a manifestation of schizophrenic pathomorphosis]

On the basis of literature data and personal experience the author indicates the pathomorphosis of schizophrenia towards its circularization. It is claimed that this phenomenon cannot be explained entirely by the use of psychotropic drugs. A study of the reasons of such "nontherapeutical" pathomorphosis requires special studies. A necessary condition for such studies is a clear selection of clinical material. In this relation the author proposes to base such studies on the origin of cyclothymic disorders which may stem from typological traits of the circular form, or from a predisposition to vital-affective registers in the premorbid personality or developed in the process of schizophrenia. Some clinical features of the disease connected with affective pathology are discussed.
