Auditory and vestibular symptoms in vestibular migraine, cochlear migraine, and Ménière's disease overlap, yet mechanisms linking migraine biology to inner ear dysfunction remain unclear. Calcitonin gene-related peptide (CGRP) is a key mediator of trigeminovascular activation and a major therapeutic target in migraine, but its contribution to cochlear dysfunction is not well defined....
No actionable change — this is animal-model mechanistic research; findings need human replication before they can influence clinical management of vestibular migraine or Ménière's disease.
Understanding how migraine biology disrupts cochlear function could eventually reveal shared treatment targets for vestibular migraine and Ménière's disease.
- 01Rat model used chronic nitroglycerin injections to simulate migraine physiology.
- 02Study examined changes in cochlear (inner ear) function alongside CGRP signaling.
- 03Results may illuminate the biological link between migraine and inner-ear disorders.
- 04CGRP is already a target for migraine drugs; cochlear involvement could be a new angle.
- 05Animal findings are preliminary and not directly transferable to clinical practice.
