Abstract


Introduction:

Involvement of the neural auditory pathway in various childhood neurological conditions has not so far been properly studied. Brain stem auditory evoked response (BSAER) is a complex neurophysiology test which is used to find abnormalities and functionally localize them within the neural auditory pathway from cochlea to brain stem.

Objective:

BSAER was done in children with various chronic neurological presentations aiming at identifying the BSAER abnormality and to characterize the pattern of abnormality to the final complete neurological diagnosis.

Method:

We followed up 73 children who came for BSAER. BSAER abnormalities were categorized into retro-cochlear, peripheral or brainstem pathology. Broad final neurological diagnoses observed were cerebral palsy, genetic syndromes, neurodegenerative disease, CNS infections and cerebral tumours.

Results:

Abnormal BSAER was found in 58%. Further localization was possible in 21% as peripheral, 10% as retrocochlear and 4% as brain stem pathology.

The findings reveal that children with some chronic neurological diseases have fairly persistent and distinct BSAER abnormalities {cerbral palsy (70%) ,Genetic syndromes (78%) and cerebral tumors(67%)}.

Conclusion:

BSAER is an important investigation to define functional auditory integrity in various childhood neurological diseases.

BSAER abnormality is common (58%) in children with various chronic neurological problems.

We propose to undertake a bigger study with the aim to characterize different BSAER patterns in different aetiologies and thus to obtain diagnostic validity for this mode of investigation to be able to use it. particularly in a resource poor setting where diagnostic neuroimaging is not easily available.
