The BERA (Brainstem Auditory Evoked Responses) test is performed in children who have suffered meningitis to check for hearing loss, which can occur in children who have suffered from meningitis. It is important to detect hearing impairment because a normal hearing is essential for normal development of speech and language. The test is harmless, i.e.; it is totally safe, and takes few minutes to complete. Earphones are placed over the child's ears, and sound is produced through the machine, and the brain waves are recorded by electrodes placed on the scalp. No injections, surgery or pain is produced. I would recommend that you get this test done.
