Can roller coasters cause seizures?

In May it will be a year that I have been experiencing seizures due to severe brain trauma (I was hit by a car, brain swelled and bled). I've only had 3 seizures, 6-4 months apart each. My family is going to Busch Gardens this weekend and I LOVE roller coasters but since my accident, I haven't tried to ride them. I was just wondering if roller coasters can bring on a seizure. I'm not exactly sure what causes the ones I've had, but I believe it's stress. I think my last one was caused by stress and A LOT of flashing lights at Disney during the parade at night. Thanks if anyone can help with this question!
