Migraines increase the risk of inner ear disorders

Migraines may be associated with disorders in the cochlear in the inner ear, including tinnitus and sudden hearing loss, a study finds.

A Taiwanese study has found that migraines increase the risk of tinnitus and sudden hearing loss. The study found than people with migraines may have a more than three times as high risk of tinnitus.

The risk for cochlea disorders — particularly tinnitus — is higher in individuals with a history of migraines, according to the study. The cochlea is located in the inner ear.

Incidence rates of cochlea disorders was found to be higher in patients with a history of migraines compared to the control group. Patients with a history of migraines had a 3.3 times increased risk of tinnitus, a 1.22 times increased risk of sudden deafness (sudden hearing loss) and a small (1.03 times) increased risk of a sensorineural hearing loss.
