The auditory brainstem response (ABR) test tells us how the inner ear, called the cochlea, and the brain pathways for hearing are working. You may also hear it called an auditory evoked potential (AEP). The test is used with children or others who cannot complete a typical hearing screening.

2013年11月18日 · The cases that we present today show expected ABR findings with both normal and abnormal auditory function at various anatomical points along the auditory pathway. They illustrate how outer, middle, and inner ear dysfunction as well as auditory neuropathy and brainstem dysfunction influence the characteristics of the click-evoked ABR.

2022年2月7日 · The auditory brainstem response (ABR) is an action potential generated by the brainstem in response to the presentation of an auditory stimulus. The auditory brainstem response is made up of a series of seven peaks and troughs which are generated by neural firing at different – but sometimes overlapping – stages of the pathway (Figure 1).

2023年1月12日 · Auditory brainstem response (ABR), or brainstem auditory Evoked Potentials (BAEP), is an objective measurement of auditory pathway function from the auditory nerve to the mesencephalon. ABR tests synchronous neural function and can estimate hearing sensitivity thresholds in individuals unable to tolerate traditional behavioral audiometry.[1]

The auditory brainstem response test (also known as ABR or BAER) is used for two purposes: To test hearing thresholds. To assess the functional status of the auditory neural pathway, which is used to determine the cause of hearing loss and candidacy for hearing loss treatments. ABR Test: What Happens. This test is painless and noninvasive.

Auditory brainstem response (ABR) testing is an objective test, evaluating the integrity of the hearing system from the level of the cochlea up through the lower brainstem. The auditory brainstem response is also commonly referred to as an ABR or BAER (brainstem auditory evoked response), depending on the region in which you live.

The ABR is used for newborn hearing screening, auditory threshold estimation, intraoperative monitoring, diagnosing hearing loss type and degree, auditory nerve and brainstem lesion detection, and in development of cochlear implants. Site-of-lesion testing is sensitive to large acoustic tumors.

Explore the essentials of Auditory Brainstem Response (ABR) Evaluations. Learn how ABR tests are conducted, their importance in detecting hearing issues, and their role in managing auditory health, especially for newborns and young children.

Also known as brainstem auditory evoked response (BAER) or auditory evoked brainstem response, auditory brainstem response is a painless diagnostic procedure used to measure the electrical activity of the auditory nerve and brainstem in response to sound.

An auditory brainstem response (ABR) evaluation is a test that allows an audiologist to measure your child’s hearing sensitivity. It is typically recommended for children who cannot be tested using a conventional hearing test or for children for whom more information is needed.
