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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
