The problem solving really protect against cognitive decline in old age?


"Use it or titlefha" is the received wisdom when it comes to cognitive ability. But there is some truth in & # 39; this old saw? Last our study suggests that depending on how "you" start with.

Studies & # 39; previous observation that looked at the effect of making mentally stimulating activities, such as puzzles, on cognitive ability supported more hypothesis "use it or titlefha". However, these studies were often based on many snapshots in time – the so-called transversal studies. To find out if there really a link between mental involvement during life and cognitive ability in old age, you need to follow the habits and mental abilities of people throughout their lives.

For our study, reported in & # 39; The BMJ, wanted to know if the mental involvement protect against cognitive decline, or those with & # 39; cognitive advantage involve more, and give the impression that this kind of & # 39; behavior is responsible for their superior skills. To answer these questions, we needed to work closely with our study participants and their intellectual capabilities judge repeatedly over time and compare their abilities with their performance in early life.

Scotland is unique because in 1947 almost all children & # 39; 11 years took the same mental aptitude test. The Scottish Council for Research in Education 'to preserve these records and contacted in 1998 allowed us to people who survived took the test.

We consider people living with & # 39; independently without dementia to five occasions over 15 years. demographic information, clinical, a & # 39; psychological questionnaire was recorded in all evaluations and was related to & # 39; changes in performance over repeated texts & # 39; verbal memory and & # 39; mental speed.

results remarkable

Our results are remarkable because they include data & # 39; childhood intelligence rare historical survey & # 39; intelligence. They showed that, at the end of life, levels & # 39; mental capacity are closely linked to current levels & # 39; involvement in & # 39; & # 39 solution; problems.

Our study could & # 39; covers intelligence and childhood education and showed that the rate of & # 39; decline in cognition in late life did not differ between people reported different levels of & # 39; engagement. However, levels & # 39; commitments were associated with revenue performance, & # 39; 64.

The childhood was associated with intelligence & # 39; intellectual commitment, which raises the question: if smarter people more involved, or are smarter because they involved? If they & # 39; the latter were true late in life, then we expect some influence on the rate of & # 39; reduction.

We have demonstrated that intellectual involvement in & # 39; this group & # 39; people without dementia not related & # 39; latest rates & # 39; cognitive decline. But engagement is linked to intellectual achievement gained from childhood to late middle age when we first started nittestjani. In other words, do puzzles and intellectual matters involving over her lifetime improve your IQ, so that when the inevitable cognitive decline set in life & # 39; later, you have a higher starting point. The reduction rate is the same for everyone, regardless of levels & # 39; engagement.

F & # 39; this stage, we can predict how intellectual engagement throughout life contributes to the protection from falling & # 39; under any intellectual limits where deemed impaired. This is achieved by starting from a higher point.

Our findings are consistent with & # 39; comparable studies segwaw older than age & # 39; 50. We have identified that problem solving is & # 39; special attention. This suggests that interventions to strengthen the resistance to aging shall contain components to solve problems, like reading & # 39; complex novels, solution & # 39; crossword puzzles and practice & # 39; musical instrument.The Conversation
