The aim of the study was to study the electroencephalographic correlates of the brain in some complicated forms of migraine. 133 (100%) patients with migraine were under observation, 66 (49.6%) with migraine status, 67 (50.4%) with chronic migraine. A 16-channel apparatus of the company «Neurosoft» carried out EEG. Thus, neurophysiological parameters of EEG were objective indicators of complicated forms of migraine, determining the zoning of the pathological process, the presence of exacerbation and aura.
