Migraine Linked to Hearing Disorders and Tinnitus

Auditory symptoms, including tinnitus and hyperacusis, are present in 15% to 49% of migraine patients, with nearly two-thirds showing objective abnormalities on hearing tests. A 2026 review published in the *Journal of Neurology* synthesizes the evidence, arguing that migraine should be understood as a systemic disorder of sensory sensitization that directly impacts the auditory system. The work, led by researchers Wandi Xu, Ni Zhai, and Jingyu Chen, moves beyond noting a simple comorbidity to propose a unified three-axis model explaining how migraine can cause or worsen hearing problems.

Migraine’s Auditory Impact Is Common and Measurable

The review compiled epidemiological and clinical data to establish the strength of the link between migraine and auditory dysfunction. The finding that up to 49% of migraineurs report co-occurring auditory symptoms is significant, but the objective data is more compelling. Auditory electrophysiological tests, which measure the brain’s electrical response to sound, reveal abnormalities in approximately two-thirds of migraine patients. This indicates the issue is not merely perceptual but involves a detectable disruption in how the auditory pathway processes signals.

These auditory phenotypes are diverse. They include sensorineural hearing loss, the persistent perception of sound known as tinnitus, and heightened sensitivity to everyday sounds, or hyperacusis. The latter shares mechanistic ground with misophonia, a condition involving strong emotional reactions to specific sounds. The authors note that these symptoms are often overlooked in standard migraine management, leaving a substantial portion of patient burden unaddressed.

A Three-Axis Model: From Ear Anatomy to Brain Networks

To explain how a headache disorder affects hearing, Xu, Zhai, and Chen propose a pathology operating on a peripheral-to-central continuum across three interacting axes.

The first axis involves anatomical and hydrodynamic vulnerabilities. The intricate blood supply and fluid systems of the inner ear are susceptible to the vascular changes and inflammation associated with migraine. This can lead to localized microvascular ischemia (reduced blood flow) and disrupted brain-ear fluid exchange, creating a hostile microenvironment for delicate hair cells and neurons.

The second axis is localized neurochemical imbalance within the cochlea and auditory nerve. Migraine-related processes, such as glutamate excitotoxicity, the release of neuropeptides like CGRP, and activation of innate immune responses, can spill over into the inner ear. This disrupts the precise chemical homeostasis required for normal hearing and can directly cause damage.

The third and overarching axis is central sensitization. Migraine primes the central nervous system to be hyperexcitable. In the auditory domain, this manifests as impaired efferent gating—the brain’s ability to filter out irrelevant sounds—and thalamocortical dysrhythmia, where abnormal neural oscillations in brain networks generate phantom perceptions like tinnitus. This central hypersensitivity can amplify signals from a slightly damaged ear or even generate auditory symptoms independently.

Directing Treatment Toward Specific Mechanisms

The traditional approach of managing migraine and auditory symptoms separately is inadequate, according to the review. The proposed three-axis model provides a framework for more targeted therapies, categorized by their clinical objective.

Blocking upstream migraine pathways is the first strategy. Preventive medications that reduce migraine frequency, such as CGRP monoclonal antibodies, could theoretically lessen the neurochemical and vascular insults to the auditory system. Treating the systemic disorder may protect the ear.

Protecting the cochlear microenvironment forms the second approach. This could involve interventions aimed at reducing oxidative stress, inflammation, or excitotoxicity locally in the inner ear, similar to some strategies explored for Ménière’s disease and tinnitus.

Correcting central hypersensitivity is the third target. Treatments like cognitive behavioral therapy, sound therapy, or neuromodulation techniques (e.g., transcranial magnetic stimulation) aim to retrain hyperactive auditory brain networks. This approach is directly relevant for managing tinnitus and hyperacusis.

Implications for Patients and Clinicians

The practical implication of this research is clear: auditory health should be a routine consideration in migraine care. Patients experiencing tinnitus, sound sensitivity, or hearing changes alongside their migraines should bring these symptoms to their neurologist’s or otolaryngologist’s attention. Conversely, individuals presenting with these auditory conditions, particularly if they are difficult to treat, should be screened for a history of migraine.

Clinically, this calls for cross-disciplinary management. Collaboration between headache specialists, audiologists, and otologists is needed to develop standardized assessment protocols and integrate treatments. For example, physical interventions for related musculoskeletal issues, such as jaw and neck exercises, may be part of a comprehensive plan, given the known connections between temporomandibular disorders, migraine, and tinnitus.

The review, “Migraine and auditory dysfunction: beyond comorbidity” (PMID: 42371148), concludes that recognizing migraine as a multisensory disorder opens new paths for research and treatment. Validating these mechanistic links through translational studies will be the next step toward improving outcomes for the large number of patients living at the intersection of migraine and auditory dysfunction.
