title: [Neurophysiological changes in hypertension detectable in an EEG analysis by the BERG-Fourier method].
abstract: Studies of the neurophysiological (bioelectrical) characteristics of the brain by Berg--Fourier method of analysis of EEG in 120 patients have established that by the quantitative parameters (magnitude of the total spectrum capacity) the majority of patients with the hypertensive disease differ from the control group and from patients with other forms of arterial hypertension. By the same criterion the patients with hypertensive disease running a crisis course significantly differed from those with hypertensive disease without crises. By visual characteristics of frequency spectra the patients with hypertensive disease in the stage of its development have typical signs of disorganization of bioelectric rhythms of the brain (predomination of "noise" types of frequency spectra). In the majority of patients with hypertensive disease during the period of stabilization frequency spectra near to normal are recorded. With hyperventilation test of patients with hypertensive disease with crises signs speaking of a possible dysfunction of the subcortical brain structures are seen.
