80% of concussions include a neck injury. The whiplash effect of many concussions can cause all of the normal concussion symptoms.

A PT who has good understanding of whiplash and concussions can often help. Upper cervical chiros help some. The most important part is that a therapist can only reduce the misalignment/subluxation. The patient needs to protect the neck so the ligaments can strengthen.
