Simmons,
A word to the wise, try to determine if the neuro-psych is going to use a Test Battery designed for head injury. He may put together his own battery of tests or use a battery arranged by others. The Halstead-Reitan Battery is a common one. The problem with neuro-psychs is some think that unless you were in a coma or unconscious for a long period, your symptoms are from psychological problems. I have had two neuro-psych assessments. Both tried to do this to me. It is even tougher to get a good assessment if you have a high IQ.
You want a good test for malingering. It will help you show the insurance company that this is a true injury, not psychosomatic or somatoform. Somatoform disorder is the kiss of death when it is put on your medical record.

Here is a good link to an explanation of the tests used.

Check out the tbi guide at www.tbiguide.com It is a fabulous resource.

The MMPI-II is commonly used and it can be misread. It can indicate a depression when in fact the same score can mean a brain injury. The neuro-psych usually will try to say you are depressed. Lloyd L Cripe Ph.D. writes about the misuse of the MMPI-II for brain injury patients.

I have been fighting with my injury for 8 years. Been there, done that, been screwed royal.
