Hi Ellie,
To many brain cells can be caused by the brain cells not disolving as we grow up and then it can cause a scar on the brain. The other way it can happen is when the mother is with child and goes through trauma causing the brain cells not to split equally on both sides of the brain and then it leaves a scar on the brain causing sz. I found out this is what happened to me when I had my wada test a few yrs. ago. Here's wishing you well and May God Bless You!
