Middle-latency auditory responses in neurological diseases

The presence of middle-latency evoked auditory potentials allows for integrity evaluation of both peripheral and the central auditory systems, and also, that of the nucleus and auditory pathways of sub-cortical region. They have also been used to study alterations of these structures in different ne...

Sumario:The presence of middle-latency evoked auditory potentials allows for integrity evaluation of both peripheral and the central auditory systems, and also, that of the nucleus and auditory pathways of sub-cortical region. They have also been used to study alterations of these structures in different neurological diseases. AIMS: the aim of this study is to verify the latency of the middle-latency evoked auditory potentials and detect the presence of any deflections in subjects with neurological diseases. MATERIALS AND METHODS: In a clinical and prospective trial, 20 patients having central neurological diseases of various etiologies were evaluated and, positive and negative deflections produced by the middle-latency evoked auditory potentials in these patients were analyzed. RESULTS: Data was statistically analyzed and showed significant modifications in middle-latency evoked auditory potentials. CONCLUSION: The authors concluded that patients with neurological disorders have either wave suppression or enlarged latency periods in relation to normal subjects.
