Voice Changes Signal Brain Health Risk
23 Sep
Summary
- Voice disorders are stronger biomarkers for cognitive decline than hearing loss.
- People with voice disorders face a 58% increased risk of cognitive decline.
- Singing and voice lessons may benefit vocal and cognitive health.
New research suggests that vocal changes, such as hoarseness or changes in pitch, may serve as an early indicator of cognitive decline. A study published in the Journal of Voice found that individuals with voice disorders have a 58% increased risk of cognitive decline, a stronger predictor than hearing loss, which is associated with a 27% increased risk.
The link between voice and brain health may stem from underlying neurological changes or communication difficulties leading to social withdrawal, which can impact cognitive stimulation. While voice changes can be caused by various factors, including misuse or medical conditions, persistent alterations warrant medical attention from a voice disorder specialist.
Encouragingly, activities like singing and voice training can benefit both vocal health and cognitive function. Participating in choirs or taking voice lessons can help prevent vocal problems and may enhance cognitive abilities such as verbal flexibility. Further research is anticipated to explore if treating voice disorders can help slow cognitive decline.
