Doctors have long recommended physical activity to help keep the brain healthy through aging. However, this study is the longest test of whether exercise makes any difference once someone starts to have memory issues. This research was performed during the pandemic, adding isolation to the list of risks for participants’ brain health.
The study included about 300 sedentary older adults with mild cognitive impairment (MCI) – a condition that is sometimes considered a precursor to Alzheimer’s disease. Half of the participants were assigned aerobic exercises, and the rest were required to perform stretching and balancing moves that only modestly raised their heart rate.
Participants in both groups attended the YMCA, and when the pandemic hit, they met with trainers over video calls from home.
After a year, cognitive testing showed that neither group had worsened, and brain scans did not show any shrinkage that typically accompanies worsening memory problems. In comparison, MCI patients involved in a similar study of long-term brain health experienced a significant cognitive decline over a year.
“Previous research has found regular physical activity of any sort may reduce damaging inflammation and increase blood flow to the brain,” said Alzheimer’s Association chief scientific officer Maria Carrillo.
Some drugs target key markers known to lead to dementia, including amyloid plaque and metabolism to help process blood sugar and fats. However, research has shown that even with medication, effective treatment of cognitive decline requires a combination of customized strategies.
As the aging population grows and cognitive impairment cases increase, there is a growing urgency to find steps people can take to help offer protection. This study shows how simple exercise may be a helpful tool in the prevention of memory issues.
The next step in research must look at how much and what kind of exercise is needed for seniors to get the brain health effects. Some experts recommend that seniors move 30 to 45 minutes four times a week, which is an enormous task for sedentary people.
Brain Function and Anti-Aging
While some degree of cognitive decline is nearly inevitable as you age, this study shows how lifestyle changes can affect brain health. Along with exercise, getting the right vitamins and nutrients for brain health is vital as you age.
The Smart Pill can help to enhance cognitive function and memory through 9 ingredients that help to support, nourish, and maximize brain health. These include ginkgo biloba, huperzine A, bacopa extract, rosemary extract, and a B vitamin complex. The formulation of these ingredients is an excellent way to help fight free radicals, boost circulation, and provide nutritional support to assist with cognitive function.
