The objective: of the work is to evaluate the influence of ultra high frequencies of electromagnetic radiation (EMF NMS) as an additional risk factor for the development of cognitive impairment in hypertension (hypertension). Materials and methods. 47 patients with AH at the age of 28–44 years (average age (30±5 years) were examined, they worked under conditions of excessive EMR NICH for a period of 4 to 22 years (average 15,0±5,9 years) and 46 patients with hypertension of the corresponding age and form of the disease (control group), which were not influenced by EHF EMF. Cognitive functions (CF) were determined using neuropsychological tests: the Ellis test (graphomotor function), direct and reverse repetition of digital series (successive functions), and cognitive function parameters on the Mini-Mental State Examination scale. Results. In patients with hypertension and the group, a decrease in motor, successive and graphomotor functions to the level of mild and moderate disorders was revealed. In group I patients, cognitive dysfunctions on the MMSE scale were revealed, their intensity was mild, but on average it was significantly more pronounced compared with group III patients (22,05±3,3 versus 26,2±2,2; р<0.001) at normal values of 28–30. Analyzing the results of the examination in men of group II, revealed significant changes from the CNS (motor functions were 8,2±0,4 points against 9,2±0,9 points in healthy men (р<0,05); successive functions, respectively 8,6±0,5 vs. 9,6±0,4 (р<0,05); graphomotor functions – 13,4±1,5, respectively, against 17±1,6 (р<0,05). The level of reactive anxiety in patients operating under conditions of microwave EMF was significantly higher (41,9±2 points versus 35,6 points; р<0,05) than in healthy men and patients in the comparison group. In patients of group I, sleep less than 6 hours was observed in 92% (including less than 5 hours in 38%); from 6 to 7 hours – in 8% of patients. In patients of group III, sleep duration from 6 to 7 hours was noted by 86%, 8 or more hours by 14% of the examined patients. Analyzing the quality of sleep (duration, nocturnal awakening, falling asleep, feeling brisk in the morning after awakening, having dreams), we obtained the following results: sleep disturbance among patients in group I was observed in 80%, whereas in patients in group III – only 35% (р<0,05). When comparing the results obtained in the surveyed group II men revealed a decrease in sleep duration and more common sleep disorders compared with healthy men and patients in group III. Conclusion. Thus, in patients with hypertension and healthy men, who are under the influence of ultrahigh frequencies of electromagnetic radiation for a long time, lesions of the nervous system in the form of impaired cognitive function with development of vascular dementia of mild degree were revealed. The correlation between the time of work under the influence of the ESA and the violations found.
