Your “um” and pauses could reveal early dementia risk

By using artificial intellect to analyze natural conversations, the team found they could predict cognitive performance with surprising accuracy, potentially opening the door to simple speech-based tools that could detect early signs of dementia long before traditional testing does. Researchers discovered that everyday speech patterns are closely tied to executive function — the mental system that powers memory, planning, focus, and flexible thinking. The little pauses, “ums,” and moments when you struggle to find the right word may reveal far more about your brain than anyone realized.
