[The psychopathology of paroxysm-like disorders in endogenous mental diseases].

45 patients with endogenous mental disorders were observed: 11 with manic-depressive psychosis and 34 with shift-like progredient schizophrenia. The peculiarity of the cases observed was the presence of paroxysmal-like disorders (PD) in clinical picture of the disease. 8 variants of PD were established: 1) with vegetative disorders, 2) with affective disturbances, 3) with obsessions, 4) with sensopathies and depersonalization, 5) with impulsive drives, 6) with alterations of consciousness (similar hysteric twilight type), 7) with hallucinations, 8) with development of manifestations of Kandinskiĭ-Clérambault's syndrome. The duration of PD varied from several seldom till a few hours, while their frequency from 1-2 in a year till several in twenty four hours. Paroxysmal-like states were accompanied by anxiety, fear or by low- differentiated sense of discomfort and "suppression", but second subjective affective feeling was neutral or even pleasant. The phenomenon which might be called as the anxious waiting for the fit was also marked. The observations of combinations of different variations of PD in one person as well as the cases of including of elements one variant in the picture of the other one permitted one to suggest the presence of a single pathobiological basis for PD rise.
