My son is 1.5 years old and has been having nocturnal myoclonic seizures since he was born. First he was on phenobarbital, then we switched to Keppra. Currently, he is taking 1,000 mg of Keppra per day. The seizures are much lighter now, but they are still a daily occurrence. The doctor has thus recommended adding Topamax. I have mixed feelings about this. I want my son to get better, and I feel fortunate that he has not had any bad side effects from the high dose of Keppra he is taking. He does not have any learning or cognitive delays. I am scared now that adding Topamax is going to give him cognitive or learning problems. Is it so bad to have light nocturnal seizures? Does anyone here have a child on both Keppra and Topamax? I feel so confused about the best way to proceed.
