The article is devoted to the search for more accurate psycho-diagnostic methods and assessment tools for determining the degree of cognitive deficits in patients with schizophrenic disorders. The concepts of "cognitive deficits" and "cognitive profile", understood as the ratio of intact and damaged components of cognitive processes and their schematic representation are discussed. The authors substantiate the need for a clear gradation of cognitive impairments in schizophrenia, development of universal translation algorithms of traditional qualitative results (meaningful) analysis of violations of cognitive activity in quantitative indicators. The article is based on the results of experimental psychological study. The investigation involved 128 patients: 76 people with Paranoid schizophrenia (F20 according to ICD-10) and 52 persons with Schizotypal disorder (F21 according to ICD-10). To assess the cognitive deficit, both traditional domestic methods and foreign tests, rarely used in the practice of a medical psychologist were conducted. The study analyzed the difference in cognitive tests performance between groups of patients with several types of schizophrenia and with different disease duration (up to 5 years and more). On the basis of quantitative data, a "cognitive profile" was lined for each disease. As a result, different variants of cognitive deficits, depending on the shape and course of the disease have been identified. The structure and dynamics of the cognitive deficits associated with schizophrenia and various forms depending on the different duration of the disease is described in detail. Also cognitive profiles compiled on this basis.
