Struggling to find the right word in conversation? New research suggests it might be more than just normal aging. Scientists from the University of Toronto found that even when older adults rarely forget words, a general slowdown in how quickly they speak could be an early sign of cognitive decline. Those who spoke more slowly tended to score lower on tests measuring planning, focus, and memory.

In the study, participants played fast-paced picture-word games while researchers tracked tiny delays in their reaction times. The results showed that raw speaking speed, not just vocabulary or getting distracted, was the strongest predictor of potential brain changes, including risk for dementia. Experts say these subtle changes can show up long before more obvious memory problems.

The good news is there are ways to help keep your brain sharp. Talking regularly, playing word games, telling stories, or even learning new words in another language can strengthen your mind. And if you or someone you know occasionally forgets a word, it’s okay—just give it a moment. Sometimes, the brain just needs a little patience.
