I had a car accident almost a year ago in which I was knocked unconscious. about 3 months later I started having retention issues and short-term memory issues. My Neurologist said I had PCS and said it could go away soon but warned it may last a long time. My symptoms got better for about two months but then got worse. I had 2 MRI's which showed nothing. My symptoms now are more like dementia, which the doctor said PCS could turn into. They are: constant pressure in the head, getting angry over little things and paranoia.

I'm going to get a second opinion next week but from what I can tell, PCS is what it is and there's not much that can be done.

Is this normal?
