Overview
The brainstem auditory evoked response is a non-invasive test used to assess the function of auditory nerve and brainstem. It measures the electrical activity generated in response to an auditory stimulus.
- Electrodes are placed on the scalp and ears
- Patient listens to sounds generated in the form of clicks and tones
- The brain activity generated in response to the sound is recorded
- New-born screening for hearing disorders
- Diagnosing auditory nerve damage
- Monitoring brain stem function in comatose patients
- Diagnosing hearing loss or deafness
- Diagnostic tools in acoustic neuroma or multiple sclerosis
