Schizophrenia is a mental illness manifested by typical personality changes. In the clinical picture of schizophrenia, the following can be distinguished: 1) structural disorders of thinking - discontinuity, resonance, logical "slips", autistic thinking, delusions; 2) emotional disorders; 3) the phenomena of depersonalization and derealization; 4) deceptions of perception (hallucinations, etc.) and a number of other disorders. Schizophrenia is not a single disease, but a group of psychoses united under one term, which can have different strength and duration of pathological manifestations and differ in the type of course. Patients with schizophrenia require observation and treatment by a psychiatrist.
