In Dr. Goadsby's VOA interview, his interpretation of his research differs somewhat:"IT'S BEEN ASSUMED FOR MOST OF THIS CENTURY THAT BOTH MIGRAINE AND CLUSTER HEADACHES ARE WHAT ARE CALLED VASCULAR HEADACHES, THAT IS TO SAY THAT THE HEADACHE IS CAUSED BY SOME SORT OF ABNORMALITY OF THE BLOOD VESSELS, AND DURING THE HEADACHE THE BLOOD VESSELS WOULD DILATE (EXPAND) AND CAUSE THE PAIN. CONSEQUENTLY, TREATMENTS WERE DIRECTED AT CONSTRICTING (SHRINKING) THE BLOOD VESSELS. WHAT OUR STUDIES HAVE SHOWN IS THAT THIS IS COMPLETELY INCORRECT, CERTAINLY FOR CLUSTER HEADACHE.CLUSTER HEADACHE IS CAUSED BY A (STRUCTURAL) PROBLEM IN THE BRAIN."
