Auditory Function in Friedreich's AtaxiaElectrophysiologic Study of a Family

Arch Otolaryngol. 1981;107(4):254-256. doi:10.1001/archotol.1981.00790400056014

• Hearing function and auditory brainstem potentials were evaluated in nine members of three generations of a family affected with Friedreich's ataxia. The characteristic findings were high-frequency sensorineural hearing impairment of varying severity and diminished or absent N1, N2, and N3 responses. These electrophysiologic aberrations correlate topographically with previously reported pathological observations.
