Recent clinical research reveals significant challenges in vestibular migraine auditory processing among affected individuals. Vestibular migraine is a complex neurological condition that often involves the trigeminovascular system. Notably, this system innervates critical auditory regions, including the superior olivary complex. Because this region is responsible for decoding spatial information, researchers hypothesized that binaural cues might be compromised. A nonexperimental, cross-sectional study was conducted to compare spatial hearing abilities between patients and healthy controls.
The study compared 17 participants with vestibular migraine against 17 healthy controls aged 20-60 years. Researchers assessed interaural level difference (ILD), interaural time difference (ITD), and Virtual Auditory Space Identification (VASI). Furthermore, they utilized the Kannada version of the Speech, Spatial and Qualities of Hearing Scale (SSQ-K). The results showed that individuals with vestibular migraine exhibited significant deficits in ILD and ITD accuracy scores. Moreover, their ability to identify sounds in a virtual environment was markedly poorer than the control group.
These deficits in vestibular migraine auditory processing have direct consequences on daily communication and quality of life. Patients often struggle to localize sounds or follow conversations in noisy environments. Consequently, clinicians should consider incorporating spatial processing assessments into routine vestibular evaluations. Early detection of these impairments allows for targeted interventions. For instance, auditory spatial training could eventually become a standard component of rehabilitation programs to improve sensory integration in these patients.
Vestibular migraine can disrupt the brain's ability to process binaural cues, such as time and level differences between ears. This disruption makes it significantly harder for patients to pinpoint the exact location of sound sources in their environment.
Clinicians use several assessments, including interaural level difference (ILD), interaural time difference (ITD), and Virtual Auditory Space Identification (VASI) scores. These tests help quantify how well a patient integrates auditory signals from both ears.
While research is ongoing, experts suggest that auditory spatial training may improve communication and quality of life. Training helps the brain adapt to sensory processing deficits, potentially serving as a valuable addition to standard vestibular rehabilitation.

A recent study demonstrates that patients with vestibular migraine face significant challenges in auditory spatial processing. These deficits in binaural cue decoding and sound localization suggest that clinical assessments should prioritize spatial hearing as part of comprehensive migraine rehabilitation.
