[The characteristics of cerebrovascular disorders in persons exposed to the effect of ionizing radiation as a result of the accident at the Chernobyl Atomic Electric Power Station].
Small doses of radioactive irradiation were found to be associated with damage to all levels of the nervous system, as evidenced by cliniconeurological investigations. But regulatory functions and vascular system get it most of all. Commonly seen in the sample was vegetovascular dystonia, also revealed were a varying degree discirculatory encephalopathy, acute disturbances in cerebral circulation, dyscirculatory myelopathy. Vascular abnormalities may develop at any age but in young adulthood they tend to occur more frequently. Clinical manifestations of vegetovascular dystonia were characterized by profound mixed type vegetative crises. Even if treated, vegetovascular dystonia tends to acquire remittent-and-progredient course leading to decompensation very soon. Strokes run atypical course: hemorrhages occur more often than not; circulatory disorders come about against the background of normal arterial blood pressure or insignificant its fluctuations. Hemorrhage may run gradually progressing course, which fact makes their diagnosis very difficult even with modern techniques being involved in relevent studies. It is not infrequently that carotid angiography does not find any structural-and-morphologic changes in the main vessels. A separate nozologic form, viz. that of discirculatory encephalopacy due to radiative irradiation, is suggested, as an entity worth introducing into the medical nomenclature.
