I do know when I was diagnosed with seizures last summer at Vanderbilt University Hospital which is a teaching hospital, several of the physicians asked me if there had ever been any sexual abuse or any other kind of abuse. Fortunately, this had not happened to me. I am telling you this to let you know that it sounds like your doctor may be on the right track since my doctors say that abuse causes seizures.
I did have some seizures as a child which were brought on by my parents divorce. Not in the way you think. I started having them when my alcoholic mother came back into my life. My Dad had a girlfriend who was like a mother to me and all of a sudden one day she was out of my life because my parents decided to remarry. I never got to see her again. I as 12 and couldn't tell anyone how I felt.
I had another seizure in 1983 when my little brother died in a car wreck and had not had any until this past summer.
Again I am sharing this with you to let you know that trauma can bring on seizures. I am certainly no expert but I wanted to share my experiences with you. Right now I am feeling a little crazy because of some recent seizures I have had.
It sounds like you have been through a lot in your life and I can feel your pain.
