Scientists have questioned whether “brain workouts” such as puzzles and online cognitive games could strengthen our minds and slow the process of aging. New research suggests that people with mild cognitive impairment may be helped.
While the study didn’t investigate whether crosswords benefit younger adults who are not dealing with cognitive decline, it suggests that keeping your mind active as you age may benefit your brain. And the research offers hope to those diagnosed with mild cognitive impairment that they may be able to stave off further declines in the memory, language problems and decision-making that are the hallmark of the condition.
“Our study shows fairly conclusively that in people with mild cognitive impairment, crossword puzzles beat the computerized games on multiple metrics,” said Murali Doraiswamy, a professor at Duke University and a co-author of the study. “So, if you have mild cognitive impairment, which is different from normal aging, then the recommendation would be to keep your brain active with crossword puzzles.
“We can’t say beyond a certain point why people do better on crosswords, but it does suggest that doing crosswords helps you,” Devanand said. Lumos Labs, the company behind the computer games in the experiment, provided access to both the crossword puzzles and their suite of games but was not involved in the design or publication of the study. Doraiswamy is a consultant to Lumos Labs., the chief of clinical interventions at the National Institute on Aging, said the agency funded the research because it’s important to find treatments that reduce the risk for Alzheimer’s disease and other types of dementia.
