Brain Surgury?

First off let me tell you a little bit about myself. I have son who is 7 at 17mths he had a stroke that left him with total left hemisphere brain damage. Since then we have dealt with seizures on a daily basis. With medication we have gone from 60 down to 10. however, we've tried tons of medicitions and this is the best we can do. Recently we're back up to 35. The medicines make him tired and the seizures we do have totally mess him up. At his neurology appt yesterday they really want to remove the either the left half of his brain or if they can find the part that is doing the seizures remove that part. I wanted to see if any parent has had a child with this type of problem and has had the brain surgury. We know the risk and the side effects we are already dealing with. I just would some stories. Thanks
