My neurologist prescribed me Topomax for a while - the stuff made me delusional and crazy. I felt much better after I stopped taking it. My family was *very* worried about my behavior while I was taking it and they were relieved once I started acting more myself after I stopped taking it. We didn't think a drug like that could cause side effects like that. But I'm very sensitive to medication.

I think it's definitely worth a try. I think most things are worth trying.

Keep in mind (and remind your Dr.) that people recovering from mTBI don't always need the typical dosage for it to work because we tend to be very sensitive to drugs.
