Peculiarities of functional hemispheric asymmetry formation in children and adolescents with hypertension

Objective: Peculiarities and age dynamics of hemispheric asymmetry investigation in children and adolescents with hypertension. Methods: 196 children and adolescents aged 10 to 17 years (15.0±1.4), including 98 patients with arterial hypertension (AH) (15.1±1.5) and 98 healthy children of the control group (14.9±1.3). The number of boys in the comparison group and the main group of patients with AH was 60 (61.2%) and 59 (60.2%), girls — 38 (38.8%) and 39 (39.8%), respectively. Results: The majority of children and adolescents with hypertension sensorimotor asymmetry differed by low intensity, indicating a decline in the dominance of the left hemisphere. Accumulation of ambiand left lateral features traced mainly in motor (53.6%) and auditory (60.2%) system, while asymmetry in the visual analyzer did not differ from the control group. Differences in the degree of hemispheric asymmetry increases in the ontogeny compared to control group. Conclusion: Identification of specificity hemispheric interaction in patients with hypertension (low asymmetry and its weak performance in ontogeny) can be considered not only as a pathological consequence of hypertension, but also as a compensatory mechanism for the redistribution of loads to the right hemisphere in terms of the functional deficit of the left hemisphere. It can be assumed that the rear parts of the brain may play a significant role in the processes of adaptation and compensation of occurring disorders in hypertension.
