[Independence of the slowly progressive form of schizophrenia]

The development stereotype of slowly progressive schizophrenia is determined by a long subclinical course (latent period), a protracted stage of florid psychopathological signs (active period) and an eventual stabilization seen in the late phases of the process. The clinical picture of the active period and the defect structure is characterized by axial symptoms, the typology of which is considered as a basis of the following systematics of slowly progressive schizophrenia: 1) latent schizophrenia; 2) slowly progressive schizophrenia with obsessions; 3) slowly progressive schizophrenia with hysterical symptoms; 4)slowly progressive schizophrenia with depersonalization; 5) hypochondriacal schizophrenia (non-delusional hypochondria); 6) slowly progressive delusional schizophrenia; 7) slowly progressive schizophrenia with a prevalence of affective disturbances; 8) schizophrenia with poor symptoms.
