Auditory Brainstem Response (ABR)

ABR measures the electrical activity of the auditory nerve and brainstem pathways in response to sound stimuli. Electrodes are placed on the scalp while the patient listens to clicks or tones. It is often used in infants, unconscious patients, or individuals who cannot give behavioral responses. The test is non-invasive but may require sedation for young children. Results help diagnose auditory neuropathy and estimate hearing thresholds. ABR is critical for neurological hearing evaluations.
