Headache study at Duke University:

The study performed at Duke University in Durham, NC, collected information from more than 2500 sources. 

A February, 2001 report from the Foundation for Chiropractic Education and Research finds that “Chiropractic patients experience improvement in the frequency and severity of their headaches.”  According to the report, Chiropractic adjustments “Appeared to result in immediate improvement in headache severity” in patients experiencing carcinogenic (neck) headache.

“What is the overwhelming common cause of 90+% of all headaches?  Our clinical experience demonstrates that the patient with stress headaches has this in common with the patient who has menstrual headaches.  The patient with migraines had this in common with the patient who suffers from cluster headaches.  That common denominator is a condition called Atlas Neuro Vascular Syndrome which compromises the integrity between the brain and body and is the underlying cause of 95% of all headaches.  Dr. Finnigan is the author of Life Beyond Headaches, www.beyondheadaches.com/headaches.html/#CD

One study of 6,000 long-term (two to 25 years) headache sufferers revealed that neck injury (whiplash, falls) was the most important factor in the cause of the headache and “should be suspected in every nonspecific case of headache.”  Braaf, M.M. and Rosner, S.J. Trauma of the cervical spine as cause of chronic headache.  Trauma, 1975, 15, pp. 441-446.

Chiropractors locate, analyze, correct and remove Atlas Neuro Vascular Syndrome when they adjust the upper spine.  This is one of the main reasons why chiropractic has such a successful history with patients who experience headaches.
