Changes in the pitch, volume or clarity of your voice could be an early warning sign of dementia, according to a new analysis. The study found that older adults who experienced diminishing voice quality were at increased risk of cognitive impairment or dementia than their peers without a voice disorder.
Experiencing a period of hoarseness is not a sign of impending cognitive decline for most people. But voice changes, especially if they are accompanied by hearing loss, a common problem in older adults, could merit a visit to the doctor and a potential workup for cognitive problems.
For the study, researchers at Drexel University tracked the health of more than 833,000 older Americans. They compared those who had been diagnosed with a voice disorder or hearing loss, or both, with a similar group who did not have either disorder. They then looked to see who went on to develop mild cognitive impairment, Alzheimer’s disease or another form of dementia.
The researchers found those with a voice disorder were at 58 percent greater risk of cognitive impairment or dementia than their peers without voice problems. The risk of cognitive problems was even greater in those who had both a voice disorder and hearing loss, a well-recognized risk factor for Alzheimer’s disease.
“We found the strongest link with dementia among patients experiencing a voice disorder and hearing loss,” said study author Dr. Robert Sataloff, a professor and chair in Drexel’s College of Medicine. “Importantly, we found that those with a voice disorder and no hearing loss were at greater risk than patients who experience hearing loss only. It may be valuable for many of these patients to talk with an otolaryngologist who can arrange a cognitive assessment to help patients develop an appropriate care plan.” The findings were published in the Journal of Voice.
The authors speculate that one reason voice disorders may contribute to cognitive decline is that they may limit social interaction, also a common problem in those with hearing loss. People who have trouble speaking or hearing may be reluctant to venture out to socialize or engage in group activities because they feel embarrassed by their limitations. But social engagement is critical for the aging brain, helping to keep the mind stimulated.
“If you have a voice disorder that impacts how your voice sounds or if it’s painful when you attempt to talk or sing, it’s only natural to participate less often in brain-supporting social or other engaging activities,” Dr. Sataloff said.
Speaking less can also mean less stimulation to the brain, which can increase dementia risk. It’s also possible that some of the changes in the brain linked to dementia may produce voice problems, but this has not been studied directly.
While most people with voice problems won’t go on to develop Alzheimer’s disease, they do merit medical attention. Many voice disorders, such as those caused by thyroid problems or by cysts on the vocal cords, for example, can be effectively treated. Speech therapists can also help people with impaired speech to communicate more effectively and confidently. Getting medical help can often improve your speaking skills, and may do good for your brain as well.
