Hi credo,

Welcome to the forum! Just in case you didn't realize it there's an Epilepsy forum on this website. I've had epilepsy for 44 yrs. and it's not uncommon to start having seizures yrs. later after a TBI. and that's because it may have caused scar tissue on the brain. You may want to also check out the forum
Coping with Epilepsy. You may get a lot of detailed answers to your questions there also. Here's wishing you only the best and May God Bless You!
