Auditory Brainstem Response (ABR/BERA)

Auditory Brainstem Response

Auditory Brainstem Response (ABR), also known as Brainstem Evoked Response Audiometry (BERA), is an advanced hearing test that evaluates how well the auditory nerve and brainstem respond to sound. This non-invasive and painless test is particularly useful for diagnosing hearing loss in newborns, young children, and individuals who cannot actively participate in traditional hearing tests.

How Does ABR/BERA Work?

During the test, small electrodes are placed on your head and behind your ears. You will hear a series of clicking sounds or tone bursts through headphones, and the electrodes will record your brain’s electrical activity in response to these sounds. The test does not require any conscious response, making it ideal for infants and people with developmental conditions.

Why is ABR/BERA Important?

ABR/BERA helps in diagnosing:

  • Hearing loss in newborns and infants who cannot respond to standard hearing tests.
  • Sensorineural hearing loss caused by nerve or inner ear damage.
  • Auditory nerve disorders such as acoustic neuroma (tumors on the auditory nerve).
  • Neurological conditions affecting the auditory pathways in the brainstem.
Who Should Get an ABR/BERA Test?
  • Newborns and infants undergoing routine hearing screening.
  • Children with speech or developmental delays.
  • Individuals with unexplained hearing loss or dizziness.
  • Patients suspected of having auditory nerve disorders.
A Safe, Accurate, and Essential Test for Hearing Health

ABR/BERA is a highly accurate test that provides valuable insights into hearing function and neurological health. The procedure is completely painless and may take 30 to 60 minutes. In infants and young children, mild sedation may be used to ensure accurate results.
