Recent research indicates that in aging individuals, talking speed is a more accurate indicator of brain health than the struggle to find words. This study suggests that slower speech, rather than pauses in conversation, may signal cognitive decline, offering a new approach to early detection and intervention for maintaining cognitive health in older adults.
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.
Next, participants were recorded as they described two complex pictures for 60 seconds each. Their language performance was then analyzed using Artificial Intelligence-based software, in partnership with Winterlight Labs. Among other things, researchers examined how fast each participant spoke and how much they paused.
Although many older adults are concerned about their need to pause to search for words, these results suggest this is a normal part of aging. On the other hand, slowing down of normal speech, regardless of pausing, may be a more important indicator of changes to brain health.
