As we age, we might begin to observe that it takes more time to recall the exact words we want to use. This situation can raise worries about cognitive deterioration and the risk of dementia.
However, a new study by Baycrest and the University of Toronto suggests that talking speed is a more important indicator of brain health than difficulty finding words, which appears to be a normal part of aging. This is one of the first studies to look at both differences in natural speech and brain health among healthy adults.
“Our results indicate that changes in general talking speed may reflect changes in the brain,” says Dr. Jed Meltzer, Baycrest’s Canada Research Chair in Interventional Cognitive Neuroscience and the lead author on this study. “This suggests that talking speed should be tested as part of standard cognitive assessments to help clinicians detect cognitive decline faster and help older adults support their brain health as they age.”
