An upper cervical chiropractic case study from Palmer College of Chiropractic as presented by the Upper Cervical Research Foundation:

Patient E had no further seizures after 1:00 pm on this day. The parents of Patient E commented that she was
showing more energy and more stability when standing. A postural change was quite evident when Patient
E was prepared for the post x-ray series. When instructed to sit up straight, Patient E’s head and upper
spine were centered over her pelvis.

While upper cervical care cannot be understood as a treatment for seizure in the medical sense, re-aligning the upper neck with a gentle protocol seems to allow the body to better heal in a variety of complex medical cases. Even in the case of severe seizure in some patients, as shown by this case study, and as experienced in many upper cervical chiropractic clinics across the country.
