THE RHEOENCEPHALOGRAPHIC STUDY OF THE INTERHEMISPHERIC ASYMMETRY OF CEREBRAL BLOOD FLOW IN HEALTHY AND MENTALLY RETARDED CHILDREN.

Aim - to study functional organization of hemodynamic processes in brain basins of healthy children and children with mild mental retardation depending on the nature of asymmetry and gradient of cerebral blood filling are investigated. The research executed in the scientific laboratory of the special and inclusive education department of the Armenian State Pedagogical University after Kh. Abovyan and Armenian State Institute of Physical Culture and Sport. The study involved children aged 8 to 11 years, a total of 131. 73 of them are healthy schoolchildren and 58 children with a low degree of mental retardation. Each category of subjects was divided into 2 age groups: 8-9 years and 10-11 years. The results of the experimental study of task performance show that interesting data have been obtained which will serve as a basis for the development of necessary means, methods, and conditions for the development of elementary practical orientation in mentally retarded elementary school children. The analysis of the results of the study allows us to highlight the following important points: in the control group, 88% of the examined patients showed a hyperfrontal pattern in terms of RI (rheogramm amplitude). In seven children, the hypermastoidal pattern was observed, and in the two children of the control group, no significant differences between the RI values in the frontal and mastoidal basins were found. The study involved 131 children aged 8 to 11 years old. 73 of them were healthy with normal physical and mental development as well as 58 children with a weak degree of mental retardation. The study was undertaken to determine which sport and physical activity allowed children with mental retardation. Established that the parameter of TPWV in 8-9-year-old and 10-11-year-old schoolchildren of the control group was significantly higher than that of experimental children in the frontal, bimostoidal and hemispheric basins.
