epilepsy
"I used to have a wonderful smart son.  About 12 years ago, I noticed changes starting to take affect in his life.  He was becoming agitated, he was loosing his memory, he had no energy.   I was told this was due to his having so many seizures.   I just this week, after having a really bad week a few weeks ago, the doctor decided to take him off of this medication in a hospital controlled setting.  After one day of not taking this medication, I am starting to see the personality of my son come back.  He had gotten to the point that he made terrible decisions, he was depressed often, he was confused and was loosing his memory and his ability to talk and remember words.   I'm sorry, but the benefits of controlling seizures was not worth this."
