According to a recent study, the resolution of psychological games, such as crosswords and sudoku, does not seem to protect people against the decline of their mental abilities.
In the past, the idea of "using or losing it", in terms of our mental abilities later in life, has been widely accepted.
The new Scottish study has shown that people who regularly participate in intellectual activities throughout their lives have higher mental abilities.
Researchers say that these activities lead to a "higher perception point", from which mental abilities diminish.
But the study has not shown that the abilities of these people decrease more slowly than others.
The study was conducted by Dr. Roger Stav, who works at the Royal Aberdeen Hospital and the University of Aberdeen. The results were published in the BMJ journal.
The study involved 498 people born in 1936 who had participated in a collective intelligence test at the age of 11 years.
The new study began at the age of 64, where they were summoned for a memory test and a test to speed up mental processes, up to 5 times over 15 years.
The study concluded that problem solving did not help prevent mental decline.
However, regular practice of intellectual stimulation activities was badociated with a level of mental capacity of the elderly.

The study used the modeling method to examine the links and could not prove a cause-and-effect relationship. Many who participated in the study were unable to continue until the end, some having abandoned, others died.
Previous studies have shown that cognitive training can improve some aspects of memory and thinking, especially in people of middle or older age.
The study concluded that what is called mental training can help people do their daily tasks better.
No studies have shown that mental training prevents dementia.
Stav and his colleagues say that although the study did not prove that solving puzzles resists mental decline, that does not mean that it is simply a waste of time.
Dr. David Reynolds, Scientific Director of the Alzheimer's Research Institute in Britain, said that the study had added to the "ongoing debate about the theory of" using or losing it ".
Reynolds notes that the study did not take into account people with dementia. "We can not say, based on these findings, whether specific activities of mental training can affect the likelihood of contracting a disease," Reynolds said.
"In addition to being mentally active, maintaining fitness, eating a balanced diet, not smoking or drinking alcohol, and maintaining a moderate weight are all recommended guidelines for improving our mental health." with age. "
"Although the exercise of mental games, such as Sudoku, does not necessarily prevent dementia, it has been shown that questioning oneself mentally regularly can improve the brain's ability to cope with the situation. "says James Beckett, head of research at the Alzheimer Society. With the disease ".
