Research indicates that voice disorders might signal a higher probability of dementia or cognitive impairment in the future. The study involved 833,417 participants aged 50 and older, examining the connection between voice disorders, hearing loss, and the potential development of conditions like Alzheimer’s disease.
Conducted by a team at Drexel University College of Medicine, the study’s findings were published in the Journal of Voice. The results showed that participants with voice disorders but no hearing loss faced a 58% increased chance of developing dementia or cognitive issues. Those with both voice disorders and hearing loss had a 104% likelihood. Overall, participants with voice disorders, with or without hearing loss, had a 29% increased probability of cognitive impairment. In contrast, participants with hearing loss alone faced a 27% greater risk.
Robert Sataloff, professor and chair at Drexel University College of Medicine, highlighted the strong connection between dementia and the combination of voice disorders and hearing loss. He noted that individuals with voice disorders but no hearing loss were at higher risk than those with hearing loss alone.
Examples of voice disorders include laryngitis, vocal cord paralysis, vocal cord lesions, and spasmodic dysphonia, according to the Cleveland Clinic. Voice challenges and hearing loss may discourage social interaction, potentially playing a role in dementia development.
Researchers emphasized that seeking treatment for voice disorders could benefit brain health. Social engagement has been shown to stimulate the brain, potentially helping to prevent dementia.
Sataloff commented on the natural link between voice disorders, hearing loss, and cognitive impairment. He suggested that discomfort during communication might lead to reduced participation in activities supporting brain health.
While the study suggests a connection, a voice disorder doesn’t guarantee future cognitive decline. Vocal issues do not necessarily indicate the onset of dementia or Alzheimer’s.
