MS has been known to cause seizures. I thought I was having seizures, but they turned out to be tonic-clonic spasms.
Oh Cici - so sorry to hear of this. What a compounding issue. I'm not versed enough in seizures to give solid information on the instances of MSers, relapse, and seizures. But, my gut says, it could be very, very possible for MSers.
If I were to research it I would start with "prevalence of seizure MS relapse"
Give that a try. And, don't forget the quotes. I hope you feel better soon, and wishing you all the best with the specialist. Hope he/she gets to the bottom of this. Be careful :) and safe.
