LONDON
An international scientific team has identified for the first time a genetic risk factor associated with common migraines and say their research could open the way for new treatments to prevent migraine attacks. Researchers who looked at genetic data from 50,000 people from Finland, Germany and The Netherlands found that patients with a certain DNA variant affecting regulation of a particular brain chemical have a greater risk of developing migraines. The results suggest that a buildup of that chemical, called glutamate, may play a role in the mechanism of migraines.
