<s>[INST] hi. my name is tami. i recently had two eegs done. one bfor taking triptal and one after. they both showed the same thing too much electrical activity on left side of my brain. to my knowledge ive never had a siezure. i was diagnosed with ms witch diff drs disagree about. all of my walking and memory problems occured aftr my neck surgery - cervical fusion in 2001. this is first dr who did eeg and thinks i have ms. wat does the eeg results mean when its too much electircal activity on left side of brain. cud it b something other than siezures/ [/INST] Hi Tami, Thank you for posting your query. I agree with you that your diagnosis has not been established, as different doctors disagree. MS (multiple sclerosis) can be diagnosed on the basis of symptoms, MRI findings and CSF (spinal tap) analysis. EEG is not helpful in the diagnosis of MS. Increased electrical activity in EEG can also occur in about 5% of normal population. So this finding without any history of seizure is not significant, and no medications are needed for this purpose. Best wishes, Chat Doctor.  </s>
