LOS ANGELES—Migraine frequency and headache-related disability are greater among migraineurs with rhinitis than among migraineurs without rhinitis, according to two studies presented at the 54th Annual Scientific Meeting of the American Headache Society. The increases are particularly pronounced among migraineurs with a mixture of allergic and nonallergic rhinitis, which is called mixed rhinitis, said Vincent T. Martin, MD, Clinical Professor of General Medicine at the University of Cincinnati.
“The differences between the rhinitis and control groups were most evident in the highest percentiles of migraine frequency,” said Dr. Martin. “This could imply that the association between rhinitis subtypes and migraine frequency and disability is most pronounced in those with more frequent migraines.”
Rhinitis Subtypes Among Migraineurs
To evaluate whether rhinitis is associated with increased headache frequency and headache-related disability in persons with migraine, Dr. Martin and his colleagues analyzed data from the American Migraine Prevalence and Prevention (AMPP) study. From 2005 to 2009, 6,008 migraineurs responded to annual follow-up surveys, which included questions about frequency of headache days per month and headache-related disability, as measured by the Migraine Disability Assessment (MIDAS) questionnaire.
