A BERA (Brainstem Evoked Response Audiometry) test, also known as Auditory Brainstem Response (ABR), is a diagnostic test that assesses the function of the auditory nerve and brainstem's response to sound stimuli, often used to evaluate hearing in infants and young children.
Here's a more detailed explanation:
BERA is a non-invasive procedure that measures the electrical activity in the brainstem in response to sound.
Electrodes are placed on the scalp and earlobes to record brain signals, which are then analyzed to assess the integrity of the auditory pathways.
BERA is particularly useful for diagnosing hearing loss in babies and young children who may not be able to participate in traditional hearing tests.
It can also help identify problems with the auditory nerve or brainstem, which can cause hearing loss or other neurological issues.
BERA is an objective test, meaning it doesn't require the patient's cooperation, which makes it suitable for infants and individuals who cannot participate in traditional hearing tests.
▪️The patient lies comfortably in a quiet room, often while sleeping or relaxed.
▪️ Electrodes are attached to the scalp and earlobes.
▪️ Sound stimuli, such as clicks or tones, are presented through earphones.
▪️ The brain's electrical responses are recorded and analyzed.
BERA can help identify hearing loss early, which is crucial for timely intervention and support for children's development.
BERA results are not affected by the patient's age, state of consciousness, or cooperation, making it a reliable test for a wide range of individuals.
The BERA test is safe and painless, making it a suitable option for infants and young children.
