According to a report on the health page of the BBC news website, new research suggests that mental powers start to dwindle at age 27, after peaking at age 22.
Professor Timothy Salthouse of Virginia University tested 2,000 healthy people aged 18-60. Study participants were tested with puzzles, word recall and spotting patterns in letters and symbols.
In the majority of tests, top performance was achieved around age 22.
In tests of brain speed, reasoning and visual puzzle-solving ability, declines in performance began at age 27. Memory testing started to decline at age 37, while vocabulary and general information held steady until age 60. Yikes !!
In other words, we may need to start anti-aging treatments earlier than previously thought!
