I had a right temporal lobectomy done 15 years ago that practically cured me of epilepsy. My life was reborn after the surgery.
Four years ago I experienced an episode of confusion for a few days. I had trouble completing sentences and couldn't remember what I had done five minutes or five months ago. By the time I had my third episode, I was pursuing my third neurologist. The origin was considered idiopathic, and the result was a total memory loss of 10 years of my life. I had no memory of the major events like 9/11 or any social events. My doctors classified it as a transient global amnesia.
Please do a story on amnesia. This is a scary position to be in for anyone.
