A Deeper Dive into Cognition & Audiology: 2022

Approximately 55 million people (globally) have acquired dementia and that number is expected to triple in the next 28 years (by 2050). Despite disappointment regarding the pharmacologic treatment of Alzheimer’s disease (there are as-of-yet no drugs which cure or reverse Alzheimer’s Disease, when cognitive disorders are screened, diagnosed, and managed early, the opportunity to positively alter the trajectory of cognitive decline increases. In this article, we’ll examine some lesser-known factors and recent peer-reviewed findings which may impact our understanding of the relationship between cognition and audition.

‘Digital Toolbox’ May Help Earlier Dementia Diagnosis

In a new study from Boston University Schools of Medicine (BUSM) and Public Health (BUSPH), participants were tested using a digital pen that recorded the entire process of completing the cognitive test and allowed the researchers to pick up subtle measures of cognitive function beyond what is captured in traditional scoring.

Study Shows How Tests of Hearing Can Reveal HIV’s Effects on the Brain

When comparing the FFR results of 68 HIV-positive adults to 59 HIV-negative adults, the investigators found that the auditory-neurophysiological responses to certain speech cues were disrupted in HIV-positive adults, even though they performed normally on hearing tests—confirming that these hearing difficulties are grounded in the central nervous system.

How Might the Brain Change When We Reintroduce Sound? Interview with Anu Sharma, PhD

New research shows that after wearing professionally fit quality hearing aids, a patient’s brain may “re-organize” its auditory processing centers back towards its original state prior to the hearing loss—with corresponding gains in auditory speech perception abilities and improvements in global cognitive function, executive function, processing speed, and visual working memory performance. Anu Sharma discusses the research findings with Douglas Beck.

Vision and Hearing Loss Associated with Increased Dementia Risk in Older Adults

One study showed having either visual or hearing impairment increased the risk of developing dementia by 11% and Alzheimer’s by 10%, and having both visual and hearing impairment raised the risk of developing dementia by 86% and Alzheimer’s by 112%. Another study demonstrated “testing for changes in multisensory function may help identify those at high risk for dementia.”

International Campaign for Better Hearing Announces Results of Hearing Loss Survey

The study results, which the The International Campaign for Better Hearing announced in a press release, conclude that 74% of respondents from around the world with hearing loss have at some point been embarrassed, while 69% have felt anxious, 64% have experienced feeling socially isolated, 59% felt tired/drained, 62% suffered from anger or frustration, and 49% have even felt unsafe as a result of their hearing loss.

Benefit of Using Telecare for Dementia Patients with Hearing Loss and Their Caregivers

A large portion of individuals with dementia also have hearing loss. When these patients are fitted with hearing aids for the first time, the use and operation of the instruments can be a struggle, and the struggle often carries over to their caregivers. This research found that the use of teleaudiology via Signia TeleCare for these new hearing aid users increased awareness, improved benefit for several different communication settings, and reduced associated stress for the caregivers.
