Query: great for nurses, doctors, and students

I used this book a lot to help study for my neuro nursing certification, and I use it still just to help refresh my memory on how it all works. I've been a neuro ICU nurse for a long time, but I still forget stuff and this book is a great, simple reference which also has given me great ideas on easy ways to explain and educate my patients and their families.
