walk and other types moderate exercise They would help rejuvenated They are older adults mental rigor, find a new clinical trial.
The lessons were addressed to the elderly, and they had problems in memory thinking skills. The researchers compared six months of moderate exercise (stopping the bike by foot or pedaling) compared to some of these problems.
Specifically, they carried out experimental improvements in executive function to enable brain care, regulate behavior, organize and achieve goals. And they did even some healthy changes in the dietTo eat fruits and vegetables, for example, the profits were slightly higher.
The effect was to reduce the brain's age to about nine years, said James Blumenthal, a professor of medicine at Duke University School of Medicine in Durham, North Carolina.
On the other hand, the same mental abilities were only among the participants in the study that received only healthy education.
According to experts, discoveries accept a general concept healthy lifestyle It helps protect brain development.
"And it's never too late to start," said Keith Fargo, director of scientific programming and Alzheimer's College. "In this study people were older, they already had a cognitive impairment [mental] and cardiovascular risk factors, and were sedentary. "
Fargo, who did not participate in the research, described the findings as "excellent news".
He said, largely, that it was a clinical trial, because he really evaluated the exercise. Previous studies have shown that physical assets are older. But research does not prove causality, Fargo said. Clinical trials as well.
Blumenthal's "never been too late" message was echoed, and he also said that the trial exercise exercise routine was very accessible. Bicyclic halted or used people three to three times a week for a period of 10 minutes with a heat of 10 minutes.
"They did not prepare for the marathon," he added.
Blumenthal said that diets had been made by some participants. They follow the diet called DASH, which is commonly recommended in people with high blood pressure. Fruits, vegetables, grains and healthy saturated fats are rich in soy, sodium, sugar and low-fat dairy products and saturated fat.
The changes agreed by Fargo are available to the majority of the elderly. "Nearly everybody climbs and sweats a few weeks," he said. "Almost everyone can eat more fruits and vegetables."
In the study, the Blumenthal group included 160 elderly people over the age of 55 with problems with memory and thinking skills. Some objective trials confirmed signs of deterioration.
Nobody had complete dementia, such as Alzheimer's. But at the beginning, the team's executive duties were similar to those under 90 years old, although the average age was 65.
Participants were assigned by random four groups: one who carried out the DASH diet, who did diets and changed diets, and only received health education.
After six months, both teams demonstrated in functional improvement tests, although the health education team declined. There was no doubt that the DASH diet was followed by people who followed the DASH diet, but the diet did not have a statistically significant difference.
Blumenthal emphasized that the study group was small, which made it difficult for the effects of the intervention. Higher education is still needed.
Whether light and diet end up delaying or preventing people.
Why does physical exercise and a healthy diet help with thinking skills?
It's not clear, said Blumenthal. But in the research, there was a correlation between physical improvements and tests in the performance of people. Likewise, if your cardiovascular risk factors (such as reducing blood pressure), your test scores have also increased.
According to Fargo, the health of the brain and the oxygen is the brain that develops brain fluid in order to improve the elderly age mental levels.
The Alzheimer's Association begins a trial that combines lifestyle modifications to stimulate mental activity and diet, social implications and puzzles and crosswords.
If these measures are contemplated mentally, they can support elderly people.
The study is featured in the 19th online edition of Neurology magazine.
