brainstem auditory evoked response

au·di·to·ry brain·stem re·sponse (ABR),

an electrophysiologic measure of auditory function using computer-averaged responses produced by the auditory nerve and the central auditory pathways principally in the brainstem to repetitive acoustic stimuli. ABR is also used to locate brainstem lesions and determine whether a hearing impairment is sensory or neural. Synonym(s): brainstem auditory evoked potential, brainstem evoked response

brainstem auditory evoked response

A method for evaluating hearing using clicking sounds and recording the responses (known as auditory evoked potentials) with EEG electrodes placed on the scalp; BAER is an objective means of diagnosing and localising early lesions of the auditory system.

Indications
BAER is used to diagnose acoustic neuroma, instrinsic brainstem lesions (e.g., multiple sclerosis, infarction, gliomas), degenerative disease (e.g., Charcot-Marie-Tooth disease, Meniere’s disease, olivopontocerebellar degeneration, stroke, Wilson’s disease), increased intracranial pressure and brain death.

brainstem auditory evoked response

BAER, Brainstem auditory evoked potential Neurophysiology A method for evaluating hearing using clicking sounds and recording the responses–known as auditory evoked potentials with EEG electrodes placed on the scalp; the early responses reflect electrical activity at the cochlea, cranial nerve VIII and brainstem; late responses are due to cortical activity; after each click, 7 consecutive potentials are recorded, designated as waves I through VII, each of which corresponds to a specific relay point in the brainstem; BAER is an objective means of diagnosing and localizing early lesions of the auditory system Indications BAER is used to diagnose acoustic neuroma, intrinsic brainstem lesions–eg, multiple sclerosis, infarction, gliomas, degenerative disease–eg, Charcot-Marie-Tooth disease, Meniere's disease, olivopontocerebellar degeneration, stroke, Wilson's disease, ↑ intracranial pressure, brain death
