Crosswords or video games: which is better for your brain?

03/11/2022

In our modern age where smartphones and apps are ubiquitous, so-called brain training games are all the rage. But people of a certain age will be much more familiar with the good old-fashioned crossword. Which is better for your brain when it comes to slowing cognitive decline? New research has provided some insights. According to the study, led by Davangere Devanand, MD, a professor and director of geriatric psychiatry at Columbia University Irving Medical Center in New York City, the humble crossword puzzle may actually be better for aging brains than new-fangled video games. “This is the first study to document both short-term and longer-term benefits for home-based crossword puzzles training compared to another intervention,” said Devanand. For the study, the researchers followed 107 adults aged 55 and over with mild cognitive impairment for 78 weeks. The participants were randomly given either crossword puzzles or brain-training games, and asked to do four 30-minute sessions weekly over three months. The participants were also asked to do a number of booster sessions up until the end of the study period. The researchers found that the people in the crossword group showed a small improvement in tests of memory and other mental skills. The results of the study are published in the New England Journal of Medicine. *Image by Steve Buissinne from Pixabay

‘Brain Training’ Good for Older People, says Study

05/11/2015

Older people benefit from playing online games that test their memory and reasoning skills, also known as ‘brain training’, according to a large-scale study. The six month experiment, which was conducted by researchers at King’s College London, involved almost 7,000 individuals aged 50 and over and was launched by the BBC’s Bang Goes The Theory. None of the volunteers who participated in the study had reported any memory or cognition problems and they were recruited from the general population as part of a collaboration between the BBC, the Medical Research Council and the Alzheimer’s Society. The researchers found that mental exercises, such as those undertaken during brain training, helped with everyday skills like cooking and shopping. A baseline was taken by testing the study subjects on a series of medically recognised cognitive tests. The group was then split into two, with one subgroup asked to play online brain training games whenever they wanted for up to 10 minutes at a time. The medically recognised cognitive tests were then redone at three and six months to see if the group which had been playing the online games displayed any detectable differences over the other group. After six months, the group that had been playing the brain games showed broader cognitive skills than those who hadn’t. Dr Doug Brown from the Alzheimer's Society said: "Online brain training is rapidly growing into a multi-million pound industry and studies like this are vital to help us understand what these games can and cannot do. “While this study wasn't long enough to test whether the brain training package can prevent cognitive decline or dementia, we're excited to see that it can have a positive impact on how well older people perform essential everyday tasks." Bigger, longer studies will now commence to dig deeper into this study’s findings.
