[Paroxysmal EEG changes in patients with multiple sclerosis].
The electroencephalograms (EEG) and visual evoked potentials (VEP) were recorded in 100 multiple sclerosis patients treated from 1981 to 1989. In 35 cases the EEG records were pathological and in 12 of them they showed paroxysmal changes. Pathological EEG were mostly seen in young patients, during the first relapse, with high degree of Kurtzke's disability score. Patients with paroxysmal changes showed on physical examination brain stem lesions that could be responsible for paroxysmal activity in EEG. The latencies of P100 wave and amplitudes of P100/N120 complex were analysed in two groups of patients (with and without paroxysmal activity in EEG). There was no statistically important difference between two groups, although in the group with paroxysmal changes in EEG some prolongation of the latency of P100 wave and a little higher amplitude of P100/N120 complex were recorded.
