A recent study from the University of Toronto found that speech rate was a more accurate indicator of brain health in older adults than word-finding difficulty. In this study, researchers asked 125 healthy adults ages 18 to 90 to describe a scene in detail. Age-related declines in concentration, speed of thinking, and ability to plan and complete tasks have been found to be related to a person’s daily speech rate.
It was also interesting that older adults’ speech rate was related to how quickly they named the object in the pictures.
All of this underscores the fact that what underlies broader age-related cognitive and language changes is a general slowdown in information processing.
