I've had three neuropsych exams for a brain tumor not Alzheimers.
A "lesion" was seen on my left temporal lobe by MRI - July 28, 2005 .... lots of hospital stuff - MRIs, VEEG, PET and neuropsych exam. Like Annie said - it's a very long and very hard exam.
At the end of that exam the neuropsychologist said that as close as possible to exactly 6 months after my Feb. 14, 2006 surgery, they would do the exam again. The exam was exactly the same one... same questions, same puzzles, etc.
When it turned out I had to have more "brain" surgery in May 2007 .... exactly 6 months later I had my third neuropsych exam.
The fantastic doctor said the exam was given to many, many people - people having all sorts of problems and it told the medical establishment many things they needed to know.
