Neurologists in the United States have announced that solving crosswords and puzzles helps slow memory loss and brain shrinkage in individuals with mild dementia. The media office of Columbia University indicates that, according to data from the World Health Organization, 55 million people worldwide currently suffer from dementia. One of the most common causes is Alzheimer's disease, which is found in 60-70% of cases. Alzheimer's leads to the death of brain cells, gradually diminishing the cognitive, behavioral, and social abilities of a person, to the point where they may forget a recent conversation or event, struggle to recognize relatives, or become confused in familiar places.
To slow this process, scientists are searching for new ways to prevent and delay the development of dementia. They have discovered that solving crosswords, puzzles, computer games, and various board games stimulate memory and attention, enhancing the cognitive performance of older adults. Neurophysiologists tested these methods on 107 elderly volunteers suffering from mild dementia and monitored their condition over 1.5 years. Researchers then subjected them to specialized ADAS-Cog tests to assess dementia symptoms.
The first test was conducted three months after the start of the "training," followed by several additional assessments. The follow-up revealed that solving crosswords and puzzles inhibited memory loss more than computer games, with this effect being consistent after the first test and during subsequent assessments of mental sharpness and memory. Both methods slowed brain shrinkage, but crosswords were found to be more effective than computer games in this regard. Researchers concluded that these mental exercises help improve memory and cognitive condition in individuals suffering from dementia.
