Allergies increase the frequency of migraine attacks
Experts at the Montefiore Headache Research Center in New York said seasonal allergic rhinitis (hay fever) increases the frequency and pain of migraine attacks. The results of their research are published in the journal Cephalalgia .
Researchers examined data from approximately 6,000 people who suffer from migraines. Previously, the participants in the experiment in the framework of the American Migraine Prevalence and Prevention project were asked to fill out questionnaires regarding their health status in 2008. Two thirds of them suffered from hay fever. After analyzing the data, the scientists concluded that participants with this condition were 33% more likely to experience severe and excruciating headaches than healthy participants.
This study of Americans was one of the first, as a result of which it was possible to identify a relationship between the frequency of severe headaches (migraines) with inflammation and irritation of the nasal mucosa caused by allergic and non-allergic triggers.
Vincent Martin, author of the study, said: “We’re not sure if allergic rhinitis actually increases the frequency of migraine attacks, or if migraine causes hay fever in patients. We assume that if a person has such allergic symptoms, then, most likely, he will have to face more frequent and painful migraine attacks. “
According to colleagues of the authors of the study, the results of the experiment can help in the treatment of migraines. “The nose is often overlooked as an important part that is involved in the initiation and severity of migraines. So while hay fever exacerbates migraine symptoms, treatment for nasal diseases can help relieve headaches in people with both ailments, ”said Richard Lipton.
Approximately 12% of US residents suffer from migraines. The victims of hay fever were between 25% and 50% of the population.
