(Ivanhoe Newswire) -- Although women with multiple sclerosis (MS)
experience migraines more frequently that those without, women who experience
migraines are not necessarily at risk to develop MS.
"While having a history of migraine diagnosis was linked to MS, women with
migraine need to know that over 99 percent of them will never develop MS, thus
having migraine should definitely not be a reason to worry about getting MS,"
study author Ilya Kister, M.D., of New York University School of Medicine, was
quoted as saying. "More research is needed since it's still not known whether
migraine is a risk factor for developing MS or if it is a condition that occurs
at the same time as MS."
The study involved 116,678 women who were part of the Nurses' Health Study II.
Of these women, 18,000 had been diagnosed with migraine at the start of the
study. The women were followed every two years for 16 years. During the study,
375 women were diagnosed with MS. Of those, 82 had reported at the beginning of
the study that they had been diagnosed by a doctor with migraine.
The study found that women with a migraine diagnosis at the beginning of the
study were 47 percent more likely to develop MS than women without a diagnosis.
The results were the same regardless of age, where they lived, Scandinavian
ancestry, vitamin D levels, smoking status and body mass index.
The research represents the first large-scale study of its kind to explore the
relationship between migraine and MS.
