[Disorders of time perception in endogenous psychoses].

Already in the normal state of health often there are alterations of subjective time experience both as acceleration and delay of the lapse of time. These impairments of time perception are more important in the psychopathological field. Except during organic brain disease disturbances of time experience are observed especially during endogenous psychoses. Depressed men usually feel an unpleasant extension of subjective time experience. In schizophrenia there is a specific distorsion of time, characterized by troubles of the biographic orientation, by magic connexion-thinking with regard to time, or by a "collapse" of the chronological order. Somatic as well as psychological conditions seem to cause these disturbances.
