• Objectives . To study the severity of impairments to executive functions in children with dyslexia and assess the efficacy of the treatment of this pathology using Cortexin. Materials and methods. A total of 60 children aged 8–11 years with specific reading disorder (F81.0) took part in the study. Reading skills were evaluated using the Fotekova and Akhutina method. Diagnostic investigations included neurological examination with tests for dyspraxia and electroencephalography with visual and quantitative analysis. Objective assessment of the severity of memory impairment was obtained using the “Operative memory” test. Quantitative assessment of attention deficit and impulsivity was obtained using the SNAP-IV scale and the Test of Variable of Attention (TOVA). The study group consisted of 30 patients receiving Cortexin and the reference group consisted of 30 patients receiving Encephabol. Control investigations for analysis of treatment efficacy were run one month after treatment ended. The control group consisted of 60 children of the same age without dyslexia. Results and conclusions. Children with dyslexia had higher levels of inattention and impulsivity, along with significantly lower measures of working memory, than children of the control group. The decreases in attention and working memory seen here, along with the increased level of impulsivity, were signs of impairment to executive functions in children with dyslexia. Courses of Cortexin and Encephabol produced significant increases in reading skills, improving attention and working memory in both groups. Treatment efficacy was somewhat higher with Cortexin (improvements were seen in 73.3% of patients) than Encephabol (60.0%). Comparative EEG analysis showed that Cortexin treatment courses in children with dyslexia were followed by significant neurophysiological changes evidencing activation of the regulatory systems of the brain.
