[Compressed spectral EEG analysis in patients with consciousness disorders complicating stroke].
In 26 patients with stroke accompanied by consciousness disorders, 48 monitoring recordings of compressed spectral array of EEG were performed by means of computerised real-time fast Fourier transformation of initial EEG with digital assay of total spectral power and percentage of frequency components in the brain hemispheres. Bilateral increase in the total spectral power and in slow-wave spectral components correlated with diffuse alterations in the initial EEG. 3 types of spectrograms were distinguished in accordance with the degree of consciousness disorders. Possibilities and prospects for application of the new method in patients with stroke are discussed.
