Researchers of the heart and headaches at Thomas Jefferson University Hospital are combining efforts to determine if a common heart defect may be the cause of some forms of migraine headaches.Investigators from the Jefferson Heart Institute and the Jefferson Headache Center are enrolling participants in a blinded study to determine if closing a Patent Foramen Ovale (PFO), a small hole or flap that can allow blood to flow between the right and left sides of the heart, can stop migraines. In newborns, the PFO closes at or shortly after birth, but in 20 percent of adults the gap remains open to some degree.More than 28 million Americans suffer from migraine headaches. Debilitating migraine headaches cause major disruption in individual’s lives and cost billions of dollars in lost work, school and medical treatment each year. More than one quarter of the … Read more

Combining two different types of treatment for migraine results in better symptom relief than taking either one of the medications, according to a study in the April 4 issue of JAMA.”Migraine is a prevalent, often debilitating disease manifested by attacks of bilateral or unilateral headache and associated symptoms, such as nausea, vomiting, and sensitivity to light and sound,” according to background information in the article. While advances have been made in treatment, results are still often unsatisfactory for many patients. None of the currently available medications taken alone provide broad coverage of the multiple pathogenic processes in migraine, which is thought to involve multiple neural pathways. A multimechanism-targeted therapy may confer advantages over a single therapy.Jan Lewis Brandes, M.D., of the Nashville Neuroscience Group, Nashville, Tenn., and colleagues evaluated the effectiveness and safety of treating migraine by combining the migraine … Read more

A University of Iowa study may provide an explanation for why some people get migraine headaches while others do not. The researchers found that too much of a small protein called RAMP1 appears to “turn up the volume” of a nerve cell receptor’s response to a neuropeptide thought to cause migraines.The neuropeptide is called CGRP (calcitonin gene-related peptide) and studies have shown that it plays a key role in migraine headaches. In particular, CGRP levels are elevated in the blood during migraine, and drugs that either reduce the levels of CGRP or block its action significantly reduce the pain of migraine headaches. Also, if CGRP is injected into people who are susceptible to migraines, they get a severe headache or a full migraine.”We have shown that this RAMP protein is a key regulator for the action of CGRP,” said Andrew … Read more

PITTSBURGH, June 21 — High school and college athletes with migraine headache characteristics after a concussion may have increased neurocognitive impairment, suggests a University of Pittsburgh Sports Medicine Concussion Program study published in the May issue of the Journal of Neurosurgery. The study results speak to the need for extreme caution in clinical evaluation and return-to-play decisions, say the authors.In the study, athletes who had characteristics of post-traumatic migraine (PTM) headache following a concussion also showed increased neurocognitive function impairment and related symptoms compared to concussed athletes with no post-injury headache or non-migraine headache.”The findings of our study strongly support the need for clinicians to exercise increased vigilance in making decisions about managing a concussed athlete with PTM and extreme caution as to when that athlete should be allowed to return to play,” said the study’s lead author, Jason Mihalik, … Read more

Patients suffering from chronic migraine headaches who have found no relief through the use of medication may find hope through occipital nerve stimulation (ONS). At the 58th annual meeting of the American Academy of Neurology, April 1-8, 2006, in San Diego, research physicians from Mayo Clinic in Arizona presented findings of their clinical studies that show ONS as a safe, effective treatment for chronic headache. ONS treatment involves implanting a neurostimulator under the skin at the base of the head. The neurostimulator delivers electrical impulses near the occipital nerves via insulated lead wires tunneled under the skin. More than 32 million Americans, 70 percent of whom are women, suffer from migraines and lose about 157 million workdays each year, according to the National Headache Foundation. Many sufferers progress to a chronic condition, experiencing headaches more than 15 days per month. … Read more
