Auditory Brainstem Response (ABR)

Auditory Brainstem Response (ABR) is a non-invasive, painless test that evaluates the function of the auditory nerve and brainstem pathways in response to sound.

Key Features

• What it Measures:
  ABR records electrical activity from the auditory nerve and brainstem following sound stimulation (e.g., clicks or tones).

• How it's Done:
  Small electrodes are placed on the scalp, and sounds are delivered through earphones while waveforms are recorded.

• Ideal for Children:
  ABR is a very good test for children or individuals who cannot perform regular audiometry, such as newborns or those with developmental delays.

• Applications:

  • Newborn hearing screening
  • Diagnosing sensorineural hearing loss
  • Detecting auditory nerve disorders (e.g., acoustic neuroma)
  • Evaluating brainstem function in neurological conditions (e.g., multiple sclerosis)

Why ABR?

• No active participation is required, making it suitable for all age groups.
• Provides objective and accurate data on hearing and neurological function.

ABR plays a crucial role in early detection and intervention for hearing impairments, especially when traditional methods are not applicable.
