[Usefulness of EEG examination in the diagnosis of multiple sclerosis with particular reference to its prognostic importance in retrobulbar neuritis].

It is known from literature that 40-60% of eeg recordings from SM patients show changes. These changes are: slow generalised activity, focal changes, and sharp waves and spikes occurring in bursts. It is established that optic neuritis often precedes the occurrence of neurological focal changes in SM. The goal of this work was the analysis of eeg recordings from SM patients before and after treatment during disease exacerbation and from patients with optic neuritis without neurological changes. Eeg recordings in optic neuritis showed changes similar to those observed in SM. Follow-up studies proved that patients with changes in eeg during neuritis were at a risk group; absence of such changes does not exclude the possibility of SM. Patients after neuritis should periodically undergo neurological examination.
