[Is there any correlation between cerebral atrophy, EEG abnormalities and epileptic attacks in patients with multiple sclerosis?].

Among 100 patients with MS, in 65 patients CT examination revealed cerebral atrophy (in 58 cortical and subcortical atrophy, in 7 patients only cortical). In 25 (25%) patients with cerebral atrophy EEG findings were focal type of paroxysmal activity. Only five patients with paroxysmal discharges had epileptic fits. Mean age in these 5 patients was 47 years, mean duration of the disease 17 years. This means that seizures in MS patients appeared in late period of the disease and no correlation was between cerebral atrophy and epileptic seizures. Paroxysmal discharges occurred more often in EEG examination, than clinical seizures.
