--(BUSINESS WIRE)--Investigators from the International Headache Genetics Consortium, a world-wide collaboration of researchers, have identified the first-ever genetic risk factor associated with common types of migraine. Researchers looked at genetic data of more than 50,000 people and found new insights into the triggers for migraines attacks, which commonly begin in puberty and but tend to affect people aged between 20 to 45 years of age. Migraine affects approximately one in six women and one in 12 men.
