During downtime — sitting on public transit, waiting for an appointment, during your lunch break, decompressing after a long day — you likely find yourself caught up in mindlessly scrolling social media. So do your brain a favor and switch it up with some cognitive games! You may be picturing paper game books, but most are available in app form, so you can take them anywhere.
Whether you prefer crossword puzzles, sudoku or a selection of other cognitive puzzles, studies have found that problem-solving, intellectually stimulating activities benefit brain function and may help protect individuals from relative cognitive decline as they age.
For example, one study using crossword puzzles and measuring mild cognitive impairment with Alzheimer’s Disease Assessment Scale-Cognitive (ADAS-Cog) scores, in which higher scores indicate higher cognitive impairment, found users who did regular crossword puzzles had a lower ADAS-Cog score. A study focused on sudoku analyzed the prefrontal cortex activity of participants as they completed the number puzzles and found that both the medial and lateral regions of the prefrontal cortex were activated. The prefrontal cortex is vital to brain function as it helps regulate important behavior like decision-making and social conduct. Another study found a close association between cognitive function in those aged 50 to 93 and the frequency with which they did number puzzles. Further supporting the idea that mentally stimulating activities like sudoku can benefit brain function.
Start a jigsaw puzzle if you have the space and want another classic puzzle option. Jigsaw puzzle benefits range from strengthening visuospatial cognition and other cognitive areas to being a great activity to enjoy with others.
