On the basis of a clinico-catanmestical study of 104 patients with adolescent schizophrenia and dysmorphobic disorders the author distinguished 3 types of such conditions. The first type was characterized by the formation of ideas of a physical defect accompanied by psychasthenia-like disturbances. Its development corresponds to the regularities typical for slowly progressive schizophrenia. The second type was characterized by conditions similar to pubertal crises, but with a certain dysharmony the third type of dysmorphophobic ideas was included into the delusional system. A complication of the dysmorphophobic state was in a direct correlation with the stage of the continuous development of the process and to a lesser extent with affective disorders as it is the case with the first two types.
