For more than 40 years, Auditory Brainstem Responses (ABRs) have been used as a diagnostic tool for hearing disorders and brainstem disorders in the pediatric audiology and neurotology and child neurology. While there are many publications in this field, this new volume will review hearing problems and neurological disorders in babies, infants and children, and discuss important new advances such as ABR figure and threshold changes with infant development. The book will also cover auditory neuropathy, its numerous and new sub-classifications. Readers will be thoroughly briefed on all the new perspectives in interpreting data. Researchers and clinicians will find the text to be a valuable tool in the correct diagnosis of hearing problems and neurological diseases among babies and infants.
