Just 6 months of walking may reverse cognitive decline, study says

"Our operating model was that by improving cardiovascular risk, you're also improving neurocognitive functioning," said lead study author James Blumenthal, a clinical psychologist at Duke University. "Du forbedrer hjernens sundhed på samme tid som forbedrer hjertes helse." Many experts are already convinced about the benefits of lifestyle interventions to reduce the risk of Alzheimer's and cardiovascular dementia, "said Dr. Richard Isaacson, who directs the Alzheimer's Prevention Clinic at Weill Cornell Medicine. "But for those who are not, this study is a randomized, clinical trial that illustrates the benefits." "You can do something today for a better brain tomorrow," said Isaacson, who was not involved in the research. [1 9659002] The study was a first, said Blumenthal, who has long studied the effects of diet and exercise on depression and overall cardiac health. "I do not think there is another study that looked at the separate and combined Effects of exercise and diet in slowing cognitive decline in patients who are vulnerable to developing dementia in later life, "he said. The study enrolled 160 adults who had high blood pressure or other risks for cardiovascular disease, who never exercised [19659007] and who had verified cognitive concerns such as difficulty making decisions, remembering or concentrating. Participants were an average age of 65, two-thirds female and equally divided between whites and minorities. Anyone diagnosed with dementia or unable to exercise was excluded.

The study was a first, said Blumenthal, who has long studied the effects of diet and exercise on depression and overall cardiac health.

“I do not think there is another study that looked at the separate and combined Effects of exercise and diet in slowing cognitive decline in patients who are vulnerable to developing dementia in later life, “he said.

The study enrolled 160 adults who had high blood pressure or other risks for cardiovascular disease, who never exercised [19659007] and who had verified cognitive concerns such as difficulty making decisions, remembering or concentrating. Participants were an average age of 65, two-thirds female and equally divided between whites and minorities. Anyone diagnosed with dementia or unable to exercise was excluded.

Researchers randomly divided participants into four groups for the six-month study. One group started the DASH diet, short for dietary approaches to stop hypertension. DASH is a widely respected heart-healthy diet that cuts salt, fatty foods and sweets while emphasizing vegetables, fruits and whole grains. This group received nutritional guidance on how to stick to the diet but was not encouraged to change their couch-potato habits.

A second group was exercised but was not encouraged to diet. For de første tre månedene var denne gruppen overvåget på et hjertesygdomme, hvor de gjorde ikke-strenuøse øvelser tre ganger i uken: De var oppvarmet i 10 minutter og så gjorde 35 minutter med kontinuerlig løping eller stasjonær sykling.

 Mediterranean style diet may prevent dementia

The third group did both: They exercised three times a week and followed the DASH diet. De vierde groep kreeg alleen advies over het verminderen van hun cardiovasculaire risico tijdens een 30-minuten-gesprek met een gezondheidsonderwijs, maar werd het niet vergeten om hun voedings- en lichaamsbeheersing te veranderen.

Alvorens hun toegewezen weg te beginnen, namen deelnemers een batterij van cognitieve tests, a three-month stress assessment and a dietary analysis. In addition, their blood pressure, blood sugar and lipids were recorded. The tests were repeated at the conclusion of the study.

Change in only six months

 Exercise is good for your body and your mind, study says

“The group who only exercised saw significantly greater improvements in their executive functioning skills than the group who did no exercise.

” The Resultaten laten zien dat gecontroleerde aerobische activiteit binnen een zeer korte periode van tijd kan hebben een significante impact op de deel van de hersenen die mensen die zichzelf verzekeren, betalen hun biljetten en dergelijke, “Isaacson zei.” Not only can you improve, but you can improve within six months! “

Blumenthal noted,” Remember, these are older adults who are completely sedentary and have verified cognitive impairments. We had no dropouts, and everyone was able to sustain the exercise program and do it on their own. That was great . “

The group who followed the DASH diet with no exercise did not show a statistically significant improvement in thinking skills, but both Blumenthal and Iscaason stressed that they only missed it by a small margin.

” I would be Cautious in saying diet did not help, because I believe it probably did, “Isaacson said.” While the brain is sitting in a separate compartment, it’s still part of the body, so everything that affects body will also affect the brain. “

However, it was the group who combined exercise and the DASH diet that saw the greatest benefit. This group averaged nearly 47 points on the overall tests of executive thinking skills, compared to 42 points for those who only exercised and about 38 points for those who were told not to change their diet and exercise habits.

In fact

No improvement in memory

Unfortunately, there was no improvement in memory for any of the groups. That’s not surprising, Isaacson said.

“We can positively improve executive function with lifestyle interventions more quickly, but memory takes longer to respond,” he said. “It could be that if this study had been continued for 18 months or used a different types of brain diet, memory too would have improved. “

What’s needed now, Isaacson added, are additional studies:” If we could get multiple centers together to do multisite studies, we will learn more. “

Because those who combined diet and exercise saw the greatest improvements, it may be that multiple lifestyle changes, not just diet and exercise, are needed to maximize success, Blumenthal said.

What’s important, he said, is that “adopting a healthy lifestyle kan verbeteren din risiko, forbedre neurokognitiv funktion, og det er ikke for sent at starte. “

Even in older people with some indication that their brains are compromised, they also benefit.”
