OBJECTIVE

To study the severity of disorders of executive functions in children with dyslexia and to assess the effectiveness of treatment of this pathology with cortexin.

MATERIAL AND METHODS

The main study group included 60 children, aged 8—11 years, with a specific reading disorder (F.81.0). Reading skills were assessed using methods of T.A. Fotekova, T.V. Akhutina. Diagnostic examination included neurological examination with dyspraxia test, electroencephalography with visual and quantitative analysis. To objectify the severity of memory impairments, the «Working memory» technique was used. Attention and impulsivity disorders were quantified using SNAP-IY and the Test of Variables of Attention (TOVA). The control group consisted of 60 children of the same age without symptoms of dyslexia. Cortexin was used to treat 30 patients from the study group, 30 patients received encephabol. A control study to analyze the effectiveness of the therapy was carried out one month after the end of therapy.

RESULTS AND CONCLUSION

Children with dyslexia are characterized by a higher level of inattention and impulsivity, as well as significantly lower indicators of working memory compared to children from the control group. The decrease in attention and working memory as well as an increased level of impulsivity are manifestations of impaired executive functions in children with dyslexia. The results of the control study after treatment showed a significant increase in reading skills in both groups. In addition, there was an improvement in indicators of attention and working memory. However, the effectiveness of treatment with cortexin was slightly higher compared to encephabol (improvement was noted in 73.3% and 60.0%of patients, respectively). According to a comparative analysis of EEG results, after a course of treatment with cortexin, children with dyslexia have significant neurophysiological changes that indicate the activation of the brain regulatory systems.
