I was diagnosed with post concussion syndrome over a year ago. The medicines I'm taking are not helping. I take topamax, nortriptyline, and tordol. I was wondering if there is another condition that had similar symptoms to post concussion syndrome. I have all of the most common symptoms such as fatigue, nausea, migrains, mood swings, difficulty concentrating and remembering, but I also loss blocks of time, I pass out, and often experience some numbness on one side of my body. Could I have something other than Post Concussion Syndrome, and if so what?
