Not just for people with brain damage. Neuropsychology is where you get your IQ tests, personality inventorys, etc. If you ever need a thorough workup on your cognitive skills and personality/psyche, chances are you'll see a neuropsychologist. Perhaps what NoodleDoodle was referring to is that they often test people who have been in accidents or have diseases that involve the CNS, and try to provide therapy for these people if they can. They also do counseling, as any other psycologist would.
