    Auditory Brainstem Response (ABR) effectively detects brainstem disorders, especially when combined with speech audiometry. This sensitive test aids in monitoring neurological conditions and therapies, offering valuable insights beyond conventional methods.

    Area of Science:

    • Neuroscience
    • Audiology
    • Neurology

    Background:

    • Auditory Brainstem Response (ABR) is a critical audiological test for evaluating brainstem function.
    • Peripheral hearing loss can significantly impact ABR test results, necessitating audiogram correlation.
    • ABR, when combined with central speech audiometry, enhances diagnostic capabilities for brainstem pathologies.

    Observation:

    • ABR demonstrated high sensitivity in detecting intra- and extra-axial brainstem lesions, often identifying abnormalities missed by conventional tests.
    • In six case studies, ABR revealed abnormalities in five, primarily through response latency measurements.
    • ABR proved sensitive to central lesions affecting the eighth nerve, where standard tests were insufficient.

    Findings:

    • ABR abnormalities indicate the level and extent of brainstem involvement or lesion effects, though not the precise lesion type or location.

  • In one instance, ABR failed to detect a lesion, but central speech testing identified the abnormality.
  • ABR monitoring provided crucial data on the efficacy of experimental embolic therapy for arteriovenous malformations (AVMs).

    • Implications:

    • ABR serves as a valuable, non-invasive tool for monitoring brainstem status in patients with suspected or confirmed disorders.
    • The study highlights ABR's potential for monitoring neural maturation, tumor progression, coma, and therapeutic interventions.
    • ABR is particularly useful for detecting brainstem disorders not visible through radiographic imaging, especially in neonates with specific precautions.
