Metaphorical use of "headache" and "migraine" in media: A longitudinal study of 1.3 million articles in major publications.

In this longitudinal study, major publications applied a metaphorical use of "headache" about half of the time. The metaphorical use of "headache" is 11-fold greater than the metaphorical use of "migraine" in the same media sample. These depictions may contribute to the trivialization of headache and the stigmatization of individuals with headache disorders. Studies with individuals affected by headache disorders are needed to clarify potential influences.
