As a Neuro ICU nurse, who deals with this very kind of thing day in and day out, I can truly sympathize!!
I find it helps to remember that, a lot of the time, these people are not normally like this. While you will see bits of their basic personality come out in them, for the most part, they are NOT themselves. Also, blood is very irritating to the brain and this contributes to why the "bleeds" are not themselves!
Now, does that mean that none of the patient's get to me? Not hardly!

But for the most part, I take it with a grain of salt! I have to agree with whoever it was that posted that they'd rather deal with a neuro pt. anyday rather than someone who's completely with it and is just being difficult!!!
So, step back, take a deep breath and remember that they're not themselves! And after you do that, thank God for drugs like Propofol and Versed (when applicable) *****
Take care
