Voice Alterations Linked to Higher Future Dementia Risk, Large US Study Finds
A new study of over 833,000 adults aged 50 and older found that changes in voice quality are associated with an increased risk of later cognitive decline or dementia.
A team from Drexel University College of Medicine examined more than 833,000 people aged 50-plus to explore links between voice disorders, hearing loss, and subsequent cognitive impairment. Tracking participants from one year after their voice and hearing assessments, the researchers observed that a voice disorder alone raised the odds of cognitive decline or dementia by 58% compared with controls, and the combination of voice disorder and hearing loss doubled the risk to 104%.
Overall, any voice issue corresponded to a 29% higher risk, while hearing loss alone added a 27% increase. The authors stress that the findings show an association, not a cause-effect relationship, and recommend that individuals with voice problems consult an otolaryngologist and consider cognitive evaluation. Potential mechanisms include reduced social interaction and speech use, which may diminish cognitive stimulation.
Why it matters
Identifying voice changes as a possible early sign of dementia could help clinicians spot at-risk adults sooner.
