The dissertation presents a theoretical generalization and a new solution of the actual scientific problem of psychiatry - the introduction of new methods of psychodiagnosis and rehabilitation in patients with paranoid schizophrenia by increasing the level of clinical and diagnostic work, restorative measures and thereby improving the quality of life for patients suffering from mental illness. On the basis of the results of the research, the algorithm for diagnosing paranoid schizophrenia and schizoaffective disorder in patients suspected of the disease was developed and introduced into practice. It has been proved that the diagnosis of schizophrenia based on the proposed method, which involves testing patients for the presence / absence of musical hearing, makes it possible to qualify the disease at an early stage, including in the prodromal stage. The prognostic and diagnostic markers for paranoid schizophrenia and schizoaffective disorder are the lack of musical hearing, high scores (more than 5) of speech-related PANSS-negative symptoms (Poor Speech, Delayed Answers, Limited Speech, Undisputable Speech), and NSA-16 Scales (Blurred affection), as well as positive symptoms of the PANSS scale (Luminosity and Disorders of Thinking). For paranoid schizophrenia, in contrast to schizoaffective disorder, the more pronounced manifestations of the negative symptoms "Violation of spontaneity and smoothness in the conversation" and "Stereotyped thinking" are more characteristic. For schizoaffective disorder more typical are "Blurred Affect," "Emotional Fences," "Difficulties in Communication," "Passive-Apathy Social Fences," "Violations of Abstract Thinking." Determining the presence of musical hearing in patients with paranoid schizophrenia and schizoaffective disorder solves the question of the possibility of predicting the course of the disease.
