What does inter-peak latency measure in BAEP results?

Inter-peak latency measures the time interval between two specific waveforms recorded in a Brainstem Auditory Evoked Potential (BAEP) test. It is particularly important because it evaluates the conduction speed of auditory pathways in the brainstem and is indicative of the functional integrity of those pathways. By assessing the time difference between two distinct peaks in the auditory response, clinicians can gain insights into the processing of auditory information along the auditory nerve and brainstem structures.

In BAEP studies, the primary focus is often on the latencies of waves such as wave I, III, and V. The inter-peak latency between these waves can highlight potential delays in the auditory pathway due to various neurological conditions. The ability to measure the interval between these waveforms provides critical data for diagnosing auditory processing disorders or identifying potential site of lesions in the auditory pathway.

Understanding inter-peak latency is crucial as it also helps clinicians assess how well the auditory system is functioning overall, which can be vital for developing treatment plans for individuals with hearing impairments or other auditory processing issues.
