In this article, we will discuss the BERA test, its procedure, cost, benefits and side effects. We will also discuss some related questions.
BERA test stands for Brainstem Evoked Response Audiometry. It is an investigative hearing test which is done in a sound sensitive environment to assess the auditory pathways of the nerve and the brain stem. While BERA testing is usually done for infants to identify possible hearing impairments, with adults, it helps in evaluating progressive neurological disorders like multiple sclerosis or auditory neuropathy.
What is the BERA Test?
The BERA test uses electrodes placed on the scalp to monitor and record the brain activity response to sound.
It identifies auditory electrical wave components (Waves I–V) that are produced during the sound stimulation.
This method enables accurate and effective assessment even when patients cannot respond using conventional methods.
How is BERA Done
The patient reclines comfortably in quiet surroundings which have controlled light levels.
Ear lobe and scalp electrodes are attached while portions of the skin are cleaned for proper contact of gels.
Listening devices deliver clicks or tone bursts.
Sound driven cerebral responses are processed and undergo interpretation.
With good cooperation from a patient, this takes about an hour & half at most while 30 minutes is the bare minimum expected time frame regardless of adherence levels.
Things to do before The Test
Avoid any sedatives or caffeine consumption prior to testing
Wash hair with plain water without conditioners for better adhesion of electrodes on scalp whilst refraining from other hair products. Strings illuminating metals must also be removed
Use toys to help keep an infant calm during testing.
Interpretation of BERA Test Results
The auditory pathways are segmented and waves I through VII are recorded in succession resulting in a total of seven waves.
In evaluating phase V, the latency and amplitude of the waves are assessed. This is the baseline for determining ranges for all other phases.
Identified delays or anomalies can suggest possible hearing impairment alongside nerve damage, neurodegenerative issues, or other relevant conditions.
Pricing of BERA Tests
As with any medical examination, the price set on conducting BERA tests will differ from region to region and from one health facility to another.
For metropolitan areas, it usually sits between 1,500 to 3,000 INR.
It is best advised to contact diagnostic centers directly for up-to-date information about their specified price rates.
Who Can Use BERA Test For Adults?
Adults suffering from unexplained hearing loss accompanied by dizziness or other neurological symptoms may benefit from undergoing the BERA test for adults.
This assists in identifying pathologies like cochlear nerve damage or retro-cochlear disorders that routine audiometric evaluations sometimes overlook.
Why is Getting a BERA Test Beneficial?
It enables precise evaluation of auditory nerve function.
Infants children and adults alike may make use of this procedure.
Assist in early diagnosis of either hearing or some neurological conditions.
Yields unbiased results which do not rely on patient participation.
Helps guide medical intervention or surgical management thereafter.
Potential Side effects Associated With Conducting A BERA Test
Side-effects stemming from such a test include soreness caused by some glue-like components used during placement of electrodes as well as small-level pain at sites where electrode foams were placed.
Conclusion
Evaluation of hearing and neural functions with the BERA test is an efficient process. It does not matter if it’s for an adult or infant, the BERA test yields meaningful results pertaining to auditory health for all ages. Knowing the normal range, costs, and procedure of the BERA test aids in accurate diagnosis and proper planning in cases of treatment. Always check with local clinics to receive favorable pricing on BERA tests and make sure to consult hearing specialists for result interpretations.
