[Clinico-electroencephalographic characteristics of various stages of dyscirculatory encephalopathy].

Clinical manifestations of dyscirculatory encephalopathy (DE) were studied in 548 patients. The occurrence of the major signs and syndromes as well as their course at different stages of the disease were revealed. Clinical criteria of classifying the patients into one of the stages were clarified. In 372 recordings of baseline and response EEG of patients at diverse stages of DE the course of various EEG indices and precise EEG characterization of each stage were given as the disease progressed. Good correlation between the course of the disease and EEG shifts allows the brain bioelectrical activity to be a tool in DE staging.
