The role of metrics in studies of hearing and cognition
Introduction When perceiving sounds in real-world listening environments, older adults encounter several sources of degradation that can interfere with the perceptual process (Figure 1). Target signals (i.e. the sounds that a listener wants to focus on) have specific acoustic characteristics...
Cognition outcomes after cochlear implantation – is there an improvement?
Older adults with a severe to profound hearing loss are more at risk of cognitive decline than adults of a similar age with milder losses or normal hearing. This poses challenges, not only in the assessment process, but also for...Hearing loss and cognition: something to think about
Irace, Chern and Golub propose causal and non-causal mechanisms for the links between hearing loss and dementia, concluding with a discussion of several proactive measures available to help preserve neurocognitive health in older adults with hearing loss. What is age-related...How cognition influences hearing aid use
Introduction Hearing aids are designed to provide amplification for individuals with poor auditory sensitivity. Signal processing algorithms are designed and implemented in hearing aids to further enhance speech intelligibility and to improve listening comfort by attenuating unwanted background noise. Sarampalis...
Foretelling: post-stroke recovery of dysphagia is predicted by cognition
Around two thirds of people in the acute phase of stroke recovery will experience dysphagia. Up to six months following a stroke this may be present in 13-18% of cases. The degree of cognitive impairment seems to be associated with...The ear-brain connection: the role of cognition in neural speech processing
Audiologists and other hearing healthcare professionals have become increasingly interested in the importance of cognitive function in the assessment and management of hearing loss, especially in light of evidence suggesting a link between hearing loss and cognitive decline in older...Cognition and hearing – you can’t test one with the other!
Cognitive Psychologist, Boaz M Ben-David, provides insights into the import of considering cognitive factors when assessing speech perception ability to maximise intervention success. Failing to do so, he suggests, is “ageist”, a predisposition healthcare professionals must avoid. Cognitive performance is...
Cochlear implantation in adults has a positive impact on overall cognitive function as early as six months postop
The link between improving hearing and thus improving cognition is an important emerging area of research in hearing rehabilitation, due to the independent association between hearing loss and dementia. This study uses visually assessed neurocognitive tests of working memory, information...
Is there an association with cognitive impairment and hearing loss in a developing country?
Hearing loss (HL) is the third leading chronic health condition among older adults. Most studies investigating HL and cognition have been performed in high-income countries. Risk factors for dementia (eg. hypertension, midlife hearing loss, obesity and physical inactivity) are more...The ear-brain connection in cochlear implant users: learning to listen again
While the cochlear implant (CI) has been a tremendous success in restoring hearing to deaf individuals, the implantation outcome still varies across CI users [1]. Some demographic factors, such as duration of deafness, and peripheral factors, such as electrode placement,...
