AUDITORY BRAIN STEM RESPONSE
Biainstem Evoked Response Audiometry (BERA) is a test measuring responses in the brain waves that are stimulated by a clicking sound to check the central auditory pathways(hearing) of the brainstem.
Indications & Need for a BERA are as follows:
1) Nervous system abnormalities
2) Children with hearing loss
3) To assess neurological functions
4) Malingering patients
5) Suspected acoustic neuroma
6) Central pontine myelinolysis
Biainstem evoked response audiometry, Auditory brain stem response, ABR audiometry, BAER (Brainstem auditory evoked response audiometry).
Procedure for Brainstem Evoked Response Audiometry (BERA)
1) Patient is asked to wash the hair the night before the test
2) Patient is made to sleep on a reclining chair
3) Electrodes are placed on the patient’s scalp, along the vertex and on each earlobe
4) Earphones are put on the ear. The patient hears a clicking sound or tone bursts through the earphones
5) The electrodes pick up the brain’s response and record it on the graph.
This Test is used to analyze
1) Hearing loss
2) Multiple sclerosis
3) Cerebrovascular accidents (stroke)
How long does the test take?
The test will range from 60-120 minutes.
How will I receive my results?
Our audiologist will share the test results immediately after completion of test. If required test result will be emailed to you accordingly.
