Health Desk-11 Dec’18: A new study said doing crossword puzzles and Sudoku does not protect against mental decline.
The idea of "use it or lose it" when it comes to our brains in later life has previously been widely accepted.
But a new Scottish study suggests it has no effect on mental decline.
Instead, results indicate that regularly doing intellectual activities throughout life boosts mental ability and provides a "higher cognitive point" from which to decline.
The study was undertaken by Roger Staff at Aberdeen Royal Infirmary and the University of Aberdeen.
However, it did mean they had a higher starting point from which decline was observed and therefore delayed the point at which impairment became significant.
This study was published in the BMJ.
