Brain speed and Cognitive Ability Peaks around age 22, plateaus, then begins to decline around age 27 according to Timothy Salthouse at the University of Virgina.
Therapies designed to stall or reverse the aging process may need to start much earlier, he said.
His seven-year study of 2,000 healthy people aged 18-60 is published in the journal Neurobiology of Aging.
Fascinating results. Even more interesting is the emergence of the finding that reaction time is correlated with longevity, that is, those who live longest are likely to have the fastest brains. So training and other interventions would seem to offer promise, even if there is an accounting for the practice effect. Marvelous. The good news is that on CL, people are starting very early--in their teens, and continuing on with no upper limit. It seems we've just scratched the surface of what's possible. Connecting these divergent threads and actualizing them is what we do at Cognitive Labs and represents our approach to theory-in-use innovation across the board, from the brain to shipping to space and sustainability.
