Agreed for the most part. In addition, neurosurgical patients who are not comatose or close to it are often exceedingly (excessively, really) deferential and almost reverent because of the nature of the work and the mystique of brain surgery. This is especially true for tumor and aneurysm surgery—"brain tumor" and "aneurysm" are highly charged terms in the lay lexicon. I've been watching the Lenox Hill documentary, and the near-idolatry you see from most of the patients and their families is real. One of the confounding things about it is that when patients do really poorly, their loved ones are almost always still grateful.
Spine and pain patients can be a little more difficult. Degenerative spine pathology tracks with obesity, smoking, etc., which retreads the points other people have already brought up, and add in the pain angle and things can get tough. But one of the beautiful things about neurosurgery is that, despite being such a specialized service, it covers almost every patient population, age range, practice setting, and type of pathology (acute vs. chronic, vascular vs. cancer vs. degenerative vs. functional, urgency ranging from hyper-emergency to cosmetic).
