HealthDay News — Asthma may increase the risk of developing chronic migraines, according to a study published in Headache.
The research included 4,446 Americans. At the start of the study in 2008, the study volunteers had fewer than 15 migraines a month. One year later, the researchers looked to see how many had chronic migraine, defined as 15 or more migraines a month.
More than 5% of people with asthma developed chronic migraine, compared to 2.5% of those without. The lead author Vincent Martin, MD, a professor of medicine and co-director of the Headache and Facial Pain Program at the University of Cincinnati, said in a university news release that having asthma was an even stronger predictor of chronic migraines than depression.
“Migraine and asthma are disorders that involve inflammation and activation of smooth muscle either in blood vessels or in the airways,” study coauthor Richard Lipton, MD, director of Montefiore Headache Center in New York City, said in the news release. “Therefore, asthma-related inflammation may lead to migraine progression.”
