Childhood central auditory processing disorder with brainstem evoked response verification.
A case of a central auditory processing disorder was caused by a unilateral low brainstem dysfunction. The diagnostic profile includes normal pure-tone hearing, normal tympanograms, absent stapedial reflexes, poor unilateral speech discrimination, and absent brainstem evoked response recordings on the affected side. History suggests this is a result of an early trauma that resulted in aberrant verbal learning. Specific diagnosis was delayed until a stapedius muscle abnormality suggested central testing.
