Sequential Studies

BAEPs are performed primarily in patients with suspected neurologic disorders to determine whether there is evidence of a brain stem lesion. BAEPs are highly sensitive to auditory conduction defects, but the findings are not pathologically specific. BAEPs provide data that are highly reproducible and objective and lend themselves to sequential studies for comparison. BAEPs are noninvasive and can be performed not only in the clinical neurophysiology laboratory but also in a hospital room or the intensive care unit. Patient cooperation is not critical, and BAEP waveforms are resistant to the effects of drugs or anesthesia. Important factors that need to be considered for accurate interpretation of BAEPs include the patient’s age, sex, and auditory acuity. The diagnostic yield of BAEPs has been confirmed in patients with acoustic neuromas, MS, or intra-axial brain stem lesions involving the auditory pathways. BAEPs appear to be complementary to structural neuroimaging studies such as MRI.
