Overview

Randomized trial evaluates cortical auditory responses in different hearing conditions, indicating their clinical relevance.

Key Points

  • To evaluate and compare cortical auditory evoked potentials (CAEPs) in individuals with normal hearing, sensorineural hearing loss (SNHL), and auditory neuropathy spectrum disorders (ANSD).
  • Included 90 participants divided into normal-hearing, SNHL, and ANSD groups.
  • CAEPs were recorded using a 2000 Hz tone burst, analyzing N1 and P2 latencies and amplitudes across groups.
  • Statistical analysis detected differences in waveform latency and amplitude.
  • Normal-hearing participants showed robust CAEP responses at 30 dBnHL.
  • The SNHL group had delayed latencies and reduced amplitudes compared to controls.
  • The ANSD group exhibited highly variable responses, with some showing absent or atypical waveforms.
