New research from Drexel University suggests that subtle changes in one's voice may be an early indicator of increased risk for developing dementia or cognitive impairment. The study, published in the Journal of Voice and involving 833,417 participants aged 50 and older, found that those with a voice disorder but no hearing loss had a 58% higher likelihood of future cognitive issues, while those with both conditions faced a 104% increased risk. The research highlights the importance of addressing voice disorders early to potentially mitigate risks associated with brain health.

Story summary
A study published in the Journal of Voice by researchers at the Drexel University College of Medicine in Philadelphia suggests that subtle changes in one's speech could be early indicators of dementia risk. The research involved 833,417 participants aged 50 and older, examining the link between voice disorders, hearing loss, or both with the development of cognitive impairment or dementia. Findings revealed that individuals with a voice disorder but no hearing loss had a 58% increased likelihood of developing dementia within a year after diagnosis, while those with both conditions saw an even higher risk at 104%. Overall, participants with any form of voice disorder faced a 29% greater probability of cognitive decline compared to those without such disorders. This study could provide early warning signs for potential cognitive issues and help in proactive medical interventions.

New research suggests that voice disorders, including shifts in vocal pitch, volume or clarity, could indicate a higher probability of developing dementia or cognitive impairment in the future.

A study involving 833,417 participants aged 50 and older examined the connection between a voice disorder, hearing loss, or both with the chance of developing cognitive impairment or dementia, including Alzheimer’s disease, beginning a year after the voice disorder and hearing loss diagnoses.

Results showed that participants with a voice disorder but no hearing loss had a 58% increased likelihood of developing dementia or cognitive issues in the future — whereas participants with a voice disorder and hearing loss had a 104% chance.

For all participants with voice disorders, with or without hearing loss, there was a 29% increased probability of developing dementia or cognitive impairment, whereas those with only hearing loss had a 27% greater risk.

“We found the strongest link with dementia among patients experiencing a voice disorder and hearing loss,” said Robert Sataloff, a professor and chair at the Drexel University College of Medicine, Science Alert reported.

“Importantly, we found that those with a voice disorder and no hearing loss were at greater risk than patients who experience hearing loss only,” he added.

Examples of voice disorders include laryngitis, vocal cord paralysis, vocal cord lesions and spasmodic dysphonia (laryngeal dystonia), among others, according to the Cleveland Clinic.

Regardless of the possible correlation between vocal issues and dementia, researchers noted that seeking treatment for a voice disorder could also benefit a patient’s brain.
uncertain
seeking → note → brain
Hearing loss and trouble speaking could discourage individuals from socializing with others, and studies have shown that social engagement can stimulate the brain and play a role in warding off dementia.
uncertain
engagement → speak → dementia
Sataloff said that it’s “only natural” for voice disorders and hearing loss to be connected to cognitive impairment.
asserted
disorders → say → impairment
Those who experience pain or discomfort when talking or singing might “participate less often in brain-supporting social or other engaging activities,” he noted.
uncertain

Despite the study’s findings, having a voice disorder doesn’t necessarily mean that future cognitive impairment is absolutely certain.

impairment → have → disorder
Additionally, it’s not guaranteed that vocal issues indicate the beginning of a decline in brain function or the onset of dementia or Alzheimer’s.
