Doing crossword puzzles and Sudoku does not protect against mental decline, according to a new study.

The idea of “use it or lose it” when it comes to our brains in later life has previously been widely accepted

But a new Scottish study suggests it has no effect on mental decline.

Instead, results indicate that regularly doing intellectual activities throughout life boosts mental ability and provides a “higher cognitive point” from which to decline.

This study published in the BMJ was undertaken by Roger Staff at Aberdeen Royal Infirmary and the University of Aberdeen.

It looked at 498 people born in 1936 who had taken part in a group intelligence test at the age of 11.

This current study started when they were about 64 years old and they were recalled for memory and mental-processing-speed testing up to five times over a 15-year period.

It found engagement in problem solving did not protect an individual from decline.

However, it did mean they had a higher starting point from which decline was observed and therefore delayed the point at which impairment became significant.

Previously, some studies have found that cognitive training can improve some aspects of memory and thinking, particularly for people who are middle-aged or older.

They found so-called brain training may help older people to manage their daily tasks better.

No studies have shown that brain training prevents dementia

And last year a report from the Global Council on Brain Health recommended that people should take part in stimulating activities such as learning a musical instrument, designing a quilt or gardening rather than brain training to help their brain function in later life.

It said the younger a person started these activities, the better their brain function would be as they aged.

Dr David Reynolds, chief scientific officer at Alzheimer’s Research UK, said the research added to the “ongoing ‘use it or lose it’ debate”.

But as the research did not consider people with dementia, “we can’t say from these results whether specific brain training activities could impact a person’s risk of the condition”.

“In addition to staying mentally active, keeping physically fit, eating a healthy balanced diet, not smoking, drinking within recommended guidelines and keeping weight, cholesterol and blood pressure in check are all good ways to support a healthy brain as we get older.”
