I've been living with epilepsy since age 4 and I spend at least 15 hours a week gaming without problems. Granted, epilepsy comes in degrees of severity, but either way if that is the diagnoses then I don't think you should worry too much.
I'm going in for an EEG on the 8th of January and I have a strong suspicion I'm going to get tested clean. Been off my meds since March and no issues yet.
