I do not know

My reading indicates that there are other forms of treatment for intractable seizures that are not responding adequately to medication.

Perhaps you should start a written list of questions/concerns so that you can have them addressed at your next appointment. It might be helpful to have someone with you. ( I know that I can get overwhelmed by too much information and the emotions of considering medical information/diagnoses/treatment options.)

Also, I wonder if you could call ahead of your appointment, let them know that you have new medical concerns and questions and would like a longer time slot. I do not know anything about encephalopathy and would also have many questions and would want time for discussion without time pressure.
