I am hoping for some suggestions on where else to look. My son is now 19. He had his first GranMal seizure at age16. Dr's first diagnosed him with epilepsy. After many tests & a sleep study they all tests came back normal . We then tested for Acid reflux. Since He complains of a Very Bad Metallic taste in his mouth ( which is followed by petimal sezuires.) The screening from the GI Dr came back Normal. My son suffers hourly with small seizures , / Convulsions & we do not know what is causing them . Any suggestions?? Desprate.
