EEGs: EEGs are not used in the diagnosis of MS. While MS may have changes seen on EEGS, those are usually with quite advanced disease. MRIs and evoked potential responses along with a complete physical/neurologic exam are generally the studies of choice. EEGs will definitely show "encephalopathy", but as there are many causes for encephalopathy it may not help if finding the etiology of the enceph.

Not at all: EEG is not of value in confirming diagnosis of MS. If encephalopathy, abnormal EEG patterns may be present, but will not reveal etiology. Other tests needed to confirm either condition.
