Making sub-server riddles and Sudoku does not have a & # 39; protect against mental decline, according to a new study.
The idea of being "used or lost" when it comes to our brain afterwards has been widely accepted.
But a new Scottish study shows that it has no impact on mental decline.
Instead, the results show that intellectual work is consistently throughout the life of its; develop mental capacity and provide a "higher mental point" from a & # 39; decline.
This study was published in the BMJ by Roger Staff at the Aberdeen Royal Infirmary and the University of Aberdeen.
He showed 498 people born in 1936 who participated in a group information test at 11.
This current research began when they were about 64 years old and were remembered for memory and depression up to five times over a 15 year period.
He found that problem-solving involvement did not protect a person from a downturn.
However, it meant that they had a higher starting point since the decline had been made and so it delayed his & point that has suffered seriously badly.
Previously, some studies have found that mental training is capable of improving some of the minds and minds, especially for middle-aged or older people.
They may be able to receive a brain training called a & # 39; Helping older people to better manage their everyday activities.
No surveys have shown that adverse training prevents dementia.
Last year, the World Council's report on Healthy Brain suggested that people should take part in stimulating activities such as musical instrument learning, wheel or garden design rather than brain training to help the brain work in world later.
He said that the young people started on those actions were better than they did; Their brain work as they were old.
Dr David Reynolds, scientific chief executive of Research UK, said that the investigation was "suspended" or "lost".
But as the study did not consider people with dementia, "we can not tell those results whether it is specific brain training activities that could affect the risk of someone of the situation ".
"As well as living in mental, physical fitness, eating a healthy, balanced diet, without smoking, drinking at – Attach recommended guides and to maintain weight, cholesterol and blood pressure in a check, there are all good ways to support a healthy brain when we get older . "
