FEATURES OF PSYCHOMOTOR ACTIVITY OF PATIENTS WITH SCHIZOPHRENIA WITH NEUROCOGNITIVE DEFICIT
The relevance of the problem is determined by the study of neurocognitive deficit in schizophrenia, as a multicomponent factor affecting all aspects of an individual's life. To reveal features of psychomotor activity and to define their value in structure of neurocognitive deficiency. 65 patients with the diagnosis - schizophrenia, paranoid form. The psychometric study was conducted on a scale of positive and negative symptoms (PANSS). The neuropsychological study included a brief assessment of cognitive function in schizophrenia (BACS). For the study of psychomotor activity used: Tapping test, assessment of dynamic tremor and determination of the maximum and optimal strength of the muscles of the hand. Results: 1. The most pronounced decrease in indicators of cognitive characteristics of the subjects on the scales: auditory and Speech memory (p=0.042165), Motor skills (p=0.000728), «Tower of London» (p=0.020942) was revealed. 2. Patients were ranked according to the severity of psychomotor activity into 4 groups from low to high. 3. When analyzing the Tapping test, heterogeneous results were obtained: in 27% of patients, the maximum rate was high, and in 19%, it was significantly reduced. 4. When comparing the indicators of dynamic tremor and the values of BACS scales, the dependence between: Total execution time (U= 67.5, at p?0.01), the Number of touches (U = 51, at p?0.001) and Motor skills was revealed; Speech fluency (U = 22.5, at p?0.05) and «Tower of London» (U = 107, at p?0.01) with number of touches. 5. Statistically significant differences between indicators of maximum strength and the Motor skills scale (U = 99.5, at p?0.001) were revealed. The character of motor manifestations associated with the structure of cognitive deficit is determined.
