Brainstem Auditory Evoked Response (BERA) is a diagnostic test that measures the electrical activity of the auditory nerve and brainstem in response to auditory stimuli.
BERA is primarily used to evaluate the integrity and function of the auditory pathway, from the ear to the brainstem.
During the test, the patient is exposed to a series of clicks or tones through headphones. Electrodes are placed on the scalp to record the electrical responses generated by the auditory nerve and brainstem.
Newborn Hearing Screening: BERA is used in newborns to assess hearing function and identify potential hearing issues early.
Diagnostic Testing: BERA is employed to diagnose various auditory disorders, including retro-cochlear lesions, auditory neuropathy, and brainstem abnormalities.
Neurological Monitoring: It can monitor neurological function during surgeries that may impact the auditory pathway.
