Drexel University study links voice changes to dementia risk

Research from Drexel University, published in the Journal of Voice, suggests that changes in voice tone, volume, or clarity may serve as early indicators of cognitive impairment or dementia in older adults.

By analyzing data from over 833,000 individuals aged 50 and older, researchers found that people with voice disorders face a 58% higher risk of developing dementia. The risk increases significantly to 104% for those experiencing both voice disorders and hearing loss simultaneously. In comparison, those with hearing loss alone showed a 27% increase in risk.

Dr. Robert Sataloff, a lead author and professor at Drexel University, noted that voice issues alone represent a greater vulnerability than hearing loss alone. The study suggests that communication difficulties may lead to social isolation and reduced mental stimulation, which could further exacerbate cognitive decline.
