New Study Shows Crossword Puzzles May Benefit Cognitive Function in Old Age

A recent study has shed light on the potential cognitive benefits of crossword puzzles in old age. The study, published in NEJM Evidence, explored the relationship between engaging in crossword puzzles and maintaining cognitive function. Researchers found that older adults with mild cognitive impairment who regularly did crossword puzzles had better cognitive function compared to those who played online cognitive exercise games.

Dr Davangere P Devanand, professor of psychiatry and neurology at Columbia University Irving Medical Center and author of the study, noted that participants who did crossword puzzles maintained or slightly improved their cognitive scores, while those who played brain games saw a decline. The study also found that crossword puzzlers showed improvement in instrumental activities of daily living, such as managing finances and medication reminders.

Previous studies have also hinted at the benefits of crossword puzzles on brain function. A 2011 study conducted by Dr Jagan Pillai at the Cleveland Clinic Lou Ruvo Center for Brain Health found that doing crossword puzzles delayed memory decline in individuals in preclinical stages of dementia.

However, experts caution that further research is needed to fully understand the extent of these benefits. While crossword puzzles may stimulate complex cognitive processes such as memory, knowledge, and verbal ability, it is difficult to determine whether they truly “strengthen” the brain in the same way exercise builds muscle.

Dr Lori Cook, director of clinical research at the Center for BrainHealth in Dallas, suggests a holistic approach to brain health. Activities that stimulate the brain in various ways, such as reading, playing board games, musical instruments, and dancing, can help maintain cognitive function. Additionally, maintaining a healthy lifestyle with proper sleep, nutrition, physical activity, and emotional balance is crucial.

Considering the unique nature of each individual’s brain and the dynamic changes it undergoes throughout life, there is no one-size-fits-all approach to prevent cognitive decline. Nevertheless, experts agree that social interactions and community engagement also play a significant role in maintaining cognitive function as we age.
