Experts Say This Common Speaking Habit Could Offer Clues About Cognitive Decline
Researchers used AI to analyze speech recordings from 67 seniors and 174 adults aged 18‑90, focusing on pauses, filler words and timing. They found that higher rates of speech disfluencies predicted lower scores on executive‑function tests, linking natural speech patterns to cognitive performance. The study, published in the Journal of Speech, Language, and Hearing Research, suggests that subtle changes in "ums" and "uhs" could serve as early, low‑cost indicators of dementia risk. Experts caution that occasional filler words are normal, but new speech difficulties merit clinical attention.
