Relation between EEG and disability scores in multiple sclerosis.

A disability-scoring and an EEG-spectral analysis was performed in patients suffering from clinically and biochemically (oligoclonal aspect in cerebro-spinal fluid) proven multiple sclerosis at two stages of their illness, that are before and after a short intensive immuno suppressive therapy. In both stages a relationship is found between the degree of disability and the amount of beta activity in the fronto-central area and the amount of the theta activity in the temporal area. Significant improvement in the clinical state of the patient and a marked increase of the mean alpha frequency in the parietooccipital region could be demonstrated after short intensive immunosuppressive therapy.
