Abstract The article deals with the study of bioelectric activity of the brain in patients with various forms of migraine, complicated by status migrainosus. The EEG-mapping was performed for 32 patients with diff erent forms of migraine. The EEG registration was carried out between the attacks. Patients were calm and active and performed functional tests. The following frequency ranges were analyzed: delta rhythm, theta rhythm, alpha rhythm, beta rhythm. The spectral powers of the rhythms in the frontal, parietal, temporal, occipital regions of the cerebral hemispheres were evaluated. The results of EEG-mapping showed that patients with diff erent forms of migraine demonstrated a decrease in reactivity of the cerebral cortex as per fast-wave indices, which was even more prominent in a group of patients with migraine without aura, as well as the activation of slow-wave activity in these patients. Analysis of the data of cartograms shows that activation of slow-wave ranges and alpha frequency inhibition was observed predominantly in the frontal-temporal zones on both sides. It proves that such peculiarity of localization of changes in the specifi c weight of the major rhythms of EEG may form typical zones of headache attack, accompanying migraines with predominance in the temporal-frontal areas. It is quite possible that frequent attacks of migrainous cephalalgia can lead to prolonged inhibition of the fast-wave components of the main rhythm and the activation of slow wave activity.
Key words migraine, status migrainosus, EEG-mapping, frequency range of rhythms, slow-wave activity, fast-wave activity of the brain
