Very interesting and intense. It has very little information about concussions and PCS. Some of the concussion information is inaccurate. We should not be surprised.

I caution people from trying to read it through. It may be way too much stimulation and cognitive effort to process. There is a very good and simple diagram of the brain that helps people understand the areas that cause certain symptoms.

Those with upper neck injuries may find the breathing and heart rate area important.
