Venki, The stupidity of some doctors is ridiculous and never ceases to amaze me. ABSOLUTELY NO ONE can predict if or when a seizure will occur. I suppose the possibility of not having seizures as time passes may increase the probability of them not returning however if medication is controlling the seizures over that period of time then all bets are off. There is never any guarantee. If your son had a normal Neurological exam, normal EEG, and MRI and is not on any anti-seizure medications during those 4-5 years perhaps his chances are higher he may not have more seizures. Never assume they are gone forever. I’ve seen seizures return after 25-45 years later. Another thing to remember is once you stop medication the possibility does exist seizures can return more severe and frequent.
