How long does Brainstem Auditory Evoked Potentials take?

Brainstem auditory evoked potential examination takes about 30 minutes, if the patient does not cooperate well during the examination, it may take longer. Brainstem auditory evoked potential is mainly used to check whether the patient's brainstem function is damaged. After wearing headphones during the examination, a series of electrical activities from scalp to brainstem are recorded through sound stimulation. This mainly reflects the functional status of auditory conduction pathways, from cochlea to brainstem. This examination is a non-invasive examination and basically has no harm to the human body.
