Others have frequent seizures no matter what you try. Yes, it can, but seizure are not the only factor. They are probably not even the most important factor.

May. Depakene was tried and he is now on Klonopin. My doctor has suggested a ketogenic diet, but thinks it may only work for a short time. What other options are there that don't involve sedation or extreme side effects such as the increased secretions with Klonopin. If these are truly infantile spasms, you should try ACTH or prednisone. The ketogenic diet is very difficult to keep a child on, but certainly may be effective.
