I was diagnosed with this several years ago and only diagnosed with it after losing vision in my left eye. I had horrible migraines plus blood pressure problems which the doctors just treated with medications. After they did a spinal tap and put me on diamox for the fluid plus have me lose weight did the symptoms subside. The only problem I really have is my vision in my left eye which will never get better because of the nerve damage. I have not had problems with decision making, but it sounds like her problem involved the opposite side of the brain and she needs to teach that area of the brain how to work again. How long was it before she was diagnosed. It was a good 3-5yrs for me.
