(Brainstem Evoked Auditory Potentials) (BEAP)

BEAP (Brainstem Evoked Auditory Potentials) is a non-invasive electrophysiological test used to evaluate the auditory pathway from the inner ear (cochlea) through the auditory nerve up to the brainstem. It records the electrical responses generated by the auditory nerve and brainstem after sound stimulation. BEAP is also known as ABR (Auditory Brainstem Response) or BERA in many clinical settings.

Purpose of the BEAP Test

• Objectively assess hearing ability
• Evaluate auditory nerve and brainstem function
• Diagnose sensorineural hearing loss
• Detect retrocochlear pathologies
• Assess hearing in infants and non-cooperative patients
• Investigate speech delay in children
• Screen high-risk newborns for hearing impairment
• Support diagnosis of neurological disorders affecting the brainstem

Preparation Before BEAP Test

• Wash hair; avoid oils or gels (For Adult)
• Stay relaxed and still (For Adult)
• Bring the child during normal sleep time (For infants and children:)
• Feed before the test to encourage sleep (For infants and children:)
• Mild sedation may be used if necessary (under medical supervision) (For infants and children:)
