Memory Treatment Centers (MTC) became amongst the very first healthcare organizations within the United States to successfully begin administering Leqembi (lecanemab-irmb)to qualified patients at its facilities.
Written by audiologist Douglas Beck, AuD, the new article highlights research on the benefits of early intervention and comprehensive hearing and listening assessment, as well as cognitive screenings for people at risk for dementia.
Amplifon Hearing Health Care, an independent provider of hearing benefit solutions in the US, announced the launch of its virtual care program to increase hearing loss awareness, prevention, and early intervention.
Is there solid scientific evidence that hearing aids can fend off cognitive decline? Researcher Samira Anderson, AuD, PhD, explains results from some of the most compelling studies on this topic—including those she has been involved with—and provides insights into this exciting area of hearing healthcare science.

Diabetes is a risk factor for Alzheimer’s disease (AD) and related dementias. More recently, hearing loss has also been linked to increased risk for AD.

The drug, called ISRIB, has already been shown in laboratory studies to restore memory function months after traumatic brain injury (TBI), reverse cognitive impairments in Down Syndrome, prevent noise-related hearing loss, fight certain types of prostate cancer, and even enhance cognition in healthy animals.

“A diet that is rich in fat and sugar, ie, the typical Western diet, is known to increase the risk of type 2 diabetes, and this way, it possibly also contributes to the development of AD,” said Professor Heikki Tanila from the A. I. Virtanen Institute for Molecular Sciences at the University of Eastern Finland.

In an article published on the ”Discover Magazine” website, author Sarah Katz challenges the view in the scientific community that deafness is a problem that needs to be cured, potentially by new CRISPR technology that could eliminate a TMC1 gene mutation.

The authors concluded that tinnitus patients may have a higher risk of AD and PD. The presence of diabetes mellitus and head injury are also thought to increase the risk for AD, while head injury, cerebrovascular disease, and osteoarthritis could increase the risk of later PD.

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.

In the study of 2,051 older adults (22.8% with hearing or visual impairment and 5.1% with both impairments) who were followed over eight years, dual sensory impairment was associated with an 86% higher risk for dementia compared with having no sensory impairments.

The researchers found that people who exhibited higher RNT patterns experienced more cognitive decline over a four-year period, and declines in memory (which is among the earlier signs of Alzheimer’s disease), and they were more likely to have amyloid and tau deposits in their brain.

A new paper in the ‘Journal of Otolaryngology-ENT Research’ summarizes key findings related to hearing loss and cognition for use by audiologists, ENTs, and other hearing care professionals.

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.

Some theories indicate that, as a result of difficulty hearing or background noise, the ear may send signals to regions in the front cortex of the brain involved in reasoning and decision making, rather than regions for speech comprehension.

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.”

Two types of hippocampal sleep waves, slow oscillations and sleep spindles, are synced in healthy individuals, but not in Alzheimer’s patients.
