The first article discusses how electrophysiological measures can supplement traditional audiometric evaluation in assessment of age-related hearing loss (ARHL). Perceptual consequences of ARHL in part, can be attributed to a reduced ability to accurately process temporal and frequency cues of speech. The frequency following response and cortical-auditory evoked potential measures may be used to identify deficits in the neural processing of speech and guide management of ARHL. The second article shares current evidence supporting an association between cognitive impairment and hearing loss. Research is ongoing to determine whether management of hearing loss with amplification devices and auditory rehabilitation reduces the risk for cognitive decline. The third article highlights a novel pharmaceutical intervention for ARHL. Specifically, the paper focused on AUT00063, a small molecule that modifies a critical ion channel, Kv3, involved in repolarization of a neural action potential within the central auditory pathway. The final article focuses on the aspects of cognition that are most relevant to behavioral auditory research and provides an overview of cognitive hearing science, auditory neuroscience, and electrophysiological measures ideal for studying how the brain processes speech.
You will be able to:
- describe the effects of aging, hearing loss, and amplification on electrophysiological measures
- identify the association between age-related hearing loss and cognition
- discuss the safety and efficacy of AUT0063 in individuals with age-related hearing loss
- describe the aspects of cognition which are most often examined in relation to auditory perception
