[EEG changes in disseminated encephalomyelitis in comparison with the findings of cerebral magnetic resonance tomography].

The electroencephalograms of 40 patients with acute symptoms of multiple sclerosis, 10 of whom presented with primary manifestation, were compared with the findings in cerebral nuclear magnetic resonance imaging. 32.5% of the patients EEGs showed abnormalities. Considering borderline findings the percentage of remarkable EEGs mounted to 60%. All of the patients presented periventricular lesions in NMR. In addition to the periventricular abnormalities between 1 and 26 district lesions per patient were found (mean = 6.5; Median = 5). In the patients group with five and more non-periventricular lesions, there were significantly more pathologic EEG-findings (p less than 0.05) than in the group with fewer lesions. Statistical correlations between EEG-abnormalities and the extent of functional deficit could not be substantiated. Neither could type and locality of EEG-changes be correlated to non-periventricular lesions in NMR.
