BAER, which stands for Brainstem Auditory Evoked Response, is a diagnostic test used to evaluate the auditory function of the brainstem. This non-invasive procedure provides valuable insights into hearing ability<\/a> and auditory nerve function, helping healthcare professionals diagnose and manage hearing loss in infants and young children. Let\u2019s explore how BAER testing is used.<\/p>\n\n\n\n

About BAER Testing<\/h2>\n\n\n

BAER testing measures the brain’s response to auditory stimuli. It assesses the integrity of the auditory pathways from the inner ear to the brainstem, providing information about the function of the auditory nerve and brainstem structures involved in hearing.<\/p>\n\n\n\n

During BAER testing, electrodes are placed on the scalp to record electrical activity generated by the auditory pathways in response to auditory stimuli. These are typically clicks or tones presented through headphones. The patient is usually awake and alert during the procedure, which takes about 30 to 60 minutes to complete. The test is used when other hearing tests aren\u2019t effective. Most infants can hear well, with only three out of 1000 newborns being born with moderate hearing loss<\/a>.<\/p>\n\n\n\n

As the auditory stimuli are presented, the electrodes detect the brain’s electrical responses, which are then amplified, filtered, and displayed on a computer monitor. The doctor analyzes these responses to assess the integrity of the auditory pathways and identify any abnormalities or hearing deficits.<\/p>\n\n\n\n

Preparations and Recovery<\/h2>\n\n\n\n

BAER testing typically requires minimal preparations and is considered safe and well-tolerated by most patients. However, there are a few important considerations:<\/p>\n\n\n\n
