New hope for migraine sufferers

16.08.2002


  • Nearly one in ten adults suffers from migraine
  • UK male sufferers alone lose 4m working days with an estimated productivity loss of £750m
  • Migraine accounts for more than half of all headaches

New collaborative research by City University, the University of Essex and the Institute of Optometry, London shows that coloured filters are effective in reducing migraine symptoms for some sufferers.

Professor Bruce Evans, of City University`s renowned Department of Optometry and Visual Science, and the Institute of Optometry, said:



"Sufferers and optometrists have suspected for some time that visual stimuli can trigger headaches, but there has been a lack of evidence-based research on the issue.

"There is research showing that some visual stimuli can result in migraine headaches. Striped patterns are especially stressful for migraine sufferers; lines of printed text may cause `pattern glare` which can start an attack of migraine.

"Our recent randomised controlled trial shows that individually prescribed coloured filters can be an effective treatment for some people whose migraines are triggered by visual stimuli."

Twenty one patients suffering from medically diagnosed migraine and whose migraines seemed to be triggered by visual factors were referred from GPs and other health carers to take part in the study. A control group was also examined and optometrists were not told which patients had migraine and which did not. While little difference was found between the migraine and control groups for eye health and function, the migraine group subjects were more prone to pattern glare than the control group.

Using individually prescribed tinted lenses showed `a consistent and marked improvement`, with headaches less frequent as a result. Professor Evans also noted that optometrists may be able to help migraine sufferers by early diagnosis and referring patients for medical advice, as well as relieving visual triggers for migraine.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
