Along with your research you need to pick up a dictionary that tells you how to spell impairment.
It's hard to take a post discussing research in brain damage and impairment seriously otherwise.
My usual stance on the whole issue is it's easier to get forgiveness than it is to get permission. I'd rather deal with a potential denial rather than the easy "no you can't do that! Now go away and leave us alone" response you're likely to get.
