People with migraines are more likely to have post-traumatic stress disorder, or PTSD. About 7.7 million adults in the United States have this anxiety disorder, noted the National Institute of Mental Health. Megan Rauscher of Reuters Health reported that a 2009 study published in Headache: The Journal of Head and Face Pain found that out of 593 adults suffering with migraines, about 30 percent of participants with chronic daily headaches and about 22 percent of participants with “episodic” headaches met criteria for PTSD, which is a higher percentage than that in the general population.
While both PTSD and migraines are more common in women — migraines affect three times as many woman as men, according to the American Migraine Foundation — a new study published in Headache found that the risk of both conditions are higher in men. Authors B. Lee Peterlin, D.O., Satnam S. Nijjar, M.D. and Gretchen E. Tietjen, M.D. reviewed the epidemiology of the two conditions and found that men who have migraine have a four times greater risk of developing PTSD compared to women with migraine. This suggests that sex hormones play a role in the co-morbidity.
