Older adults who regularly do word and number puzzles have sharper brains, according to a study.

Puzzles

ITV News reports that the more regularly adults aged 50 and over attempted puzzles such as crosswords and Sudoku, the better their brain function, it found.

Academics at the University of Exeter and King’s College London carried out research into more than 19,000 participants who completed an online survey.

They were asked to report how frequently they engage in word and number puzzles and undertake a series of cognitive tests sensitive to measuring changes in brain function.

The scientists found the more regularly participants engaged with the puzzles, the better they performed on tasks assessing attention, reasoning and memory.

From their results, researchers calculated that people who engage in word puzzles have a brain function equivalent to 10 years younger than their age, on tests assessing grammatical reasoning, and eight years younger than their age on tests measuring short-term memory.

Study leader Dr Anne Corbett, of the University of Exeter Medical School, said: “We’ve found that the more regularly people engage with puzzles such as crosswords and Sudoku, the sharper their performance is across a range of tasks assessing memory, attention and reasoning.

“The improvements are particularly clear in the speed and accuracy of their performance. “In some areas the improvement was quite dramatic – on measures of problem-solving, people who regularly do these puzzles performed equivalent to an average of eight years younger compared to those who don’t.

“We can’t say that playing these puzzles necessarily reduces the risk of dementia in later life but this research supports previous findings that indicate regular use of word and number puzzles helps keep our brains working better for longer.”

The study used participants from the Protect online platform, run by the two universities, which allows researchers to conduct and manage large-scale studies without the need for laboratory visits.
