The Brainstem Auditory Evoked Response (BAER) test is a safe and non-invasive diagnostic procedure used to assess how well your brain processes sound.
During the test, small electrodes are placed on the scalp and earlobes. When clicking sounds are delivered through earphones, the electrodes record the brainβs response to the sound signals. These readings are used to evaluate the function of the auditory nerve and brainstem pathways.
This test is especially crucial for:
Detecting hearing loss in newborns and infants
Identifying neurological disorders like Multiple Sclerosis
Screening for brainstem tumors like acoustic neuromas
