I'm new to the board, but I have had epilepsy since 14 mos. old and am now 50. I have been on almost all the meds out there, and I know that if you take meds for too long, they stop working or not working as good. I am currently on keppra, am coming off of tegretol and getting on lamictal. Coming off of tegretol is not easy, I am having anxiety attacks.
But anyways, I would talk to your husband's doc and see what he says. I have been doing okay, have had some complex partials. Also, had brain surgery in 1998, and am doing much better. I am sure as I get older, I might have problems.
Have you given any thought to veeg? That's where you are admitted to the hospital and hooked up and are watched on video 24/7. I don't know if your hubby would want to do that, but maybe it could help??
Take care and keep the faith!
