Downs and Crum1 recently reported four case studies in which acoustic reflex responses were observed at reduced hearing levels (HLs). All subjects had CNS abnormalities with concomitant central auditory processing disturbances. The investigators suggested that a hyperactive acoustic reflex response may represent reduced central inhibition on peripheral auditory function. The youngest subject was 53 years of age. No information is available about hyperactive acoustic reflex responses in a younger population. The following supplemental case study describes a young child with a confirmed neurologic disorder secondary to meningitis, a hyperactive acoustic reflex response, and suspected central auditory processing disturbance.
