Meta Description: Hearing loss in childhood is generally called auditory neuropathy. It is a disorder that effects the neural processing of auditory stimuli in the brain and does so either directly or indirectly. Diagnostic testing in the evaluation of auditory neuropathy includes a battery of hearing tests.
Auditory Neuropathy Spectrum Disorder is the full name for this disorder. Other names that are often used interchangeably are Auditory Neuropathy and Auditory Dyssynchrony. For the discussion in this article AN will be used. Auditory Neuropathy is the main cause of hearing impairment in about 10% or more of deaf patients. Due to the fact that there are considerable variations in patient presentation of symptoms, one must not only understand the physiological testing that must be used but the subtleties in patient presentation that are often overlooked.
Diagnostic testing in the evaluation of Auditory Neuropathy includes a battery of hearing tests.

One differentiation in auditory neuropathy versus other ontological diseases is the presence of normal outer hair cell function along with abnormal inner hair cells.
