Abnormal brain activity in migraineurs is not restricted to attacks

23.06.2010
Typically, migraine is considered to be an episodic disorder with discrete attacks of headache. But new research by Dr. Till Sprenger and his team from UCSF Headache Group and Technische Universität München found increased network activity -- stronger functional connectivity -- bilaterally in the visual, auditory and sensorimotor network in migraineurs.

"There has been increasing evidence that the processing and perception of sensory stimuli is abnormal even outside of attacks," said Dr. Sprenger. "Now our findings underline that abnormal brain activity in migraineurs is not restricted to attacks – that there is an extensive alteration of functional connectivity in multiple networks reflecting the migrainous phenotype, emphasizing that migraine is a disorder of the brain."

Findings will be presented at the American Headache Society's 52nd Annual Scientific Meeting in Los Angeles this week.

"This research has been anticipated for some time and is absolutely fundamental to our understanding of migraine," said David Dodick, M.D. president of the American Headache Society. "It is likely that the observed interictal abnormalities of brain activity and connectivity explains the predisposition to spontaneous attacks, as well as the vulnerability of migraineurs to a myriad of external and endogenous triggers. It may also explain the persistence of headache in some sufferers and the persistence of symptoms in between attacks of pain (e.g. sensitivity to light)."

More than 200 scientific papers and posters are being presented during the AHS meeting which is expected to draw some 500 migraine and headache health professionals including doctors, researchers, and specialists.

About the American Headache Society

The American Headache Society® (AHS) is a professional society of health care providers dedicated to the study and treatment of headache and face pain. The Society's objectives are to promote the exchange of information and ideas concerning the causes and treatments of headache and related painful disorders. Educating physicians, health professionals and the public and encouraging scientific research are the primary functions of this organization. AHS activities include an annual scientific meeting, a comprehensive headache symposium, regional symposia for neurologists and family practice physicians, publication of the journal Headache and sponsorship of the AHS Committee for Headache Education (ACHE). www.americanheadachesociety.org

About the American Migraine Foundation

The American Migraine Foundation is a non-profit foundation supported by the American Headache Society and generous donors dedicated to the advancement of migraine research. The mission of this newly formed foundation is to support innovative research that will lead to improvement in the lives of those who suffer from migraine and other disabling headaches. www.americanmigrainefoundation.org

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
