Suggest Treatment For Poor Coordination And Inability To Think Clearly

I've recently been diagnosed w/ demyelinatinating disease caused by severe migraines which i've had for about 20 yrs. They when mis diagnosed by other doctors in the past until recently. 2 MRIs and blood tests revealed scar tissue on the brain and ruled out other things such as MS, etc. I'm unsure exactly what to do; kind of scared that I won't be able to continue my previous profession being that it has affected my coordination and my ability to think clearly. It's only been about a week since I've been on medication called Topiramate. Any ideas? Age 38 6"-0" Approx. 195-200lbs.
