I have been on SSDI for 5 or 6 years. I was approved for the behavioral issues that come with PCS. The occupational psychologist read my NPA and determined that I would not tolerate a work environment very well. It took me 3 years to get approved but I found out that the first application was messed up and I should have been approved in the first round.

The SSDI Blue Book lists the many qualifying limitations. Don't just look at neuro issues, check the mental health and other issues, too.
