[The bioelectrical activity of the brain in Urov (Kashin-Bek) disease]

EEG studies of 112 patients in different stages of the uric (Kashin-Beck) disease revealed pathological shifts in the brain biopotentials, which were beyond the aging changes. Analysis of the EEG tracing demonstrated that the index of alpha-activity along with a progressive severity of the disease, especially in the 2nd and 3d stage, was statistically less, while the per cent of pathological forms of potentials increased. In a rhythmic photostimulation there were disorders in the brain reactivity. These data point to a diffuse lesion of the brain. A correlation between clinical, EEG and other studies permit to consider the uric disease as a chronic disorder leading to an early aging of the organism.
