Migraine impairs the auditory protective mechanism: a potential biomarker

Migraine is a prevalent neurological disorder frequently accompanied by auditory symptoms such as tinnitus and hyperacusis. While their associations suggest shared neural mechanisms, objective evidence regarding the specific involvement of brainstem-mediated auditory efferent pathways in migraine remains limited....

✦ Clinical Takeaway ✦

Audiologists treating patients with co-occurring migraine, tinnitus, or hyperacusis should be aware of a potential shared neural mechanism; if validated, acoustic reflex or related measures may serve as biomarkers, but this is not yet ready for routine clinical application.

✦ Why It Matters ✦

Identifying a measurable biomarker linking migraine to auditory dysfunction could open new diagnostic and therapeutic pathways for patients with tinnitus and hyperacusis who also suffer from migraines.

✦ Key Points ✦

01Migraine may impair the auditory protective reflex (the system that reduces sensitivity to loud sounds).
02Shared neural pathways between migraine and auditory symptoms like tinnitus and hyperacusis are proposed.
03A potential biomarker based on this impaired mechanism is identified, which could aid diagnosis.
04Findings suggest migraine is not purely a headache disorder but affects broader sensory processing.
05Results are preliminary and require replication before clinical adoption.
