Alternate Names : Evoked auditory potentials, BAEP - brainstem auditory evoked potentials, Evoked response audiometry
Definition
Brainstem auditory evoked response (BAER) is a test to measure the brain wave activity that occurs in response to clicks or certain tones.
Why is the Test Performed?
The test is done to help diagnose nervous system problems and hearing losses (especially in low birth weight newborns), and to assess neurological functions.
How is the Test Performed?
You lie on a reclining chair or bed and remain still. Electrodes are placed on your scalp and on each earlobe. The earphones give off a brief click or tone. The electrodes pick up the brain's responses to these sounds and record them. You do not need to be awake for this test.
How to Prepare for the Test?
You may be asked to wash your hair the night before the test.
How will the Test Feel?
There is little discomfort.
