Addressing hearing loss can prevent dementia, according to a recent study.
A team of researchers from the University of Newcastle in the UK has suggested a new theory on how hearing loss can lead to dementia and help prevent the condition from reversing hearing loss, according to a report published in the Neuron Journal.
“Ear disorders have been challenged to explain how degenerative problems in the brain can occur,” said Tim Griffith, a professor in the Faculty of Medical Sciences at Newcastle University.

Finding the link between hearing and dementia has crucial effects, the authors wrote in a published report.
“When cortical degeneration is difficult to overcome, if not impossible, hearing loss or hearing aids or cochlear implants are widely treated. Thus, an understanding of the mechanisms that combine the two may be of widespread importance to public health,” the authors wrote. .
Explaining how hearing loss causes changes in brain activity, the researchers noted that there may be elevated levels of abnormal proteins associated with Alzheimer’s disease, leading to neurodegenerative conditions associated with memory loss. The researchers looked at three main aspects: the lack of input from sound leading to brain contraction; The underlying cause of hearing and dementia; And brain resources have become unavailable to perform other functions because they have to compensate for hearing loss.
According to the study, the team suggested a new approach to hearing and memory loss that focused on memory centers in the temporal lobe of the brain. Experts have recently found that the temporal lobe is not only associated with long-term memory for events and locations, but also manipulates short-term storage and audit data, according to a news release about the study.
“We suggest a new theory based on how we use what is generally considered a memory system in the brain when we have difficulty hearing in a real-world environment,” Griffiths said in the publication.

A member of the Faculty of Medical Sciences at Newcastle University, co-author Dr. “This memory system, which is involved in difficult hearing, is the most common site for the onset of Alzheimer’s disease,” Will Sadley said in the release. “We propose that altered activity in the memory system due to hearing loss and Alzheimer’s disease process stimulate each other.”
The authors report that epidemiological studies have found that midlife hearing loss is an “independent risk factor for dementia” and account for an account% of millions of cases worldwide.
A team of experts developed a theory linking hearing loss with dementia by drawing conclusions from various human studies and animal samples, recommending further research to investigate this new theory.
