The Brain Benefits of Doing Crosswords

“Crosswords keep your brain sharp” is one of those claims everyone repeats. So what does the evidence actually show? The honest answer: crosswords are a genuinely good mental workout, with some encouraging research — but they are not a magic shield against cognitive decline.

What the research suggests

Large observational studies have linked regular word-puzzle use with better performance on tests of attention, reasoning and memory in older adults. A widely reported 2019 analysis from the University of Exeter’s PROTECT study found that the more often participants did word puzzles, the better their scores on a range of cognitive tasks. A 2022 clinical trial also suggested crosswords may help certain people with mild memory concerns more than some computerized brain games.

Where the evidence stops

These findings show association and modest benefit — not proof that crosswords prevent dementia. People who do puzzles often differ in other ways too. Think of crosswords as one enjoyable part of a mentally active life, alongside reading, social connection, sleep and exercise, rather than a cure.
