Auditory brainstem response in wave VI for the detection of learning disabilities

The auditory brainstem response is an evoked potential (BAEP) commonly used to study auditory function in either normal or pathological conditions. These responses are recorded from the scalp and are composed of five to seven positive vertex waves within the first 10 ms after an auditory stimulus, although generally only the first five vertex waves are taken into account in clinical studies. To consider auditory evoked potentials technique is a way to learn the functionality of a part of the brain neuronal groups that intervene in the learning process by studying the behaviour of waves I to VI. The latest advances in neuroscience have revealed the existence of different brain activity in the learning process that can be highlighted through the use of non-invasive, innocuous, low-cost and easyaccess techniques such as, among others, the BAEP that can help us to detect early possible neurodevelopmental difficulties for their subsequent assessment and cure. To date, only the latency data obtained, observing the first to V waves and mainly in the left ear were taken into account. This work shows that it is essential to take into account latencies and amplitudes of both ears, with these latest data it has been possible had diagnosed more precise some cases than with the previous data had been diagnosed as “normal”despite showing signs of some alteration that motivated the new consultation to the specialistPeer ReviewedPostprint (published version
