Reddit mentions of Neurocritical Care Essentials: A Practical Guide

The hand book of NSG is a must

Neurocritical Care is a must if you have a MICU/SICU

Neuroanatomy Through Clinical Cases is a good textbook which focuses on all the major points and many fine details you will need to know as you go through your career. I use this book when I make lectures.

You'll also want to read some review articles on ICP management, vasospasm dx and tx following SAH, hypertonic saline, neuro imaging.

There are some youtube videos that will help get you started with imaging:

For Head CT

For C-spine CT

For MRI in general

For Lumbar MRI

I recommend referring back to these resources as you see patients with the afflictions as it will help it stick. If you just read about things without using them in practice I think you'll find it is easily forgotten. Best of luck!
