Healthy lifestyle behaviours including regular exercise and a heart-healthy diet may slow the development of a condition that affects one’s memory, says a recent study.
Researchers published the results of their study in the Journal of the — American Geriatrics Society.
According to the U.S. National Library for Medicine, signs of mild cognitive impairment may include frequently losing things, forgetting to go to events and appointments, and having more trouble coming up with words than other people of your age.
Some experts believe that risk factors for heart disease also are risk factors for dementia and late-life cognitive decline and dementia.
The research team said the healthy lifestyle behaviours that slow the development of heart disease could reduce heart disease risk and also slow cognitive decline in older adults with Cognitive impairment without dementia (CIND).
These behaviours include regular exercise and a heart-healthy diet, such as the DASH (Dietary Approaches to Stop Hypertension) diet.
In order to investigate their theory, the researchers designed a study titled “Exercise and Nutritional Interventions for Cognitive and Cardiovascular Health Enhancement” (or Enlighten for short).
The goal of the study was to examine the effects of aerobic exercise (sometimes known as “cardio” or “cardiovascular” exercise because it involves activities that increase the circulation of oxygen through the blood) and the DASH diet on cognitive functioning in older adults with CIND.
The study examined 160 adults 55-years-old or older. The study participants were older adults who didn’t exercise and had memory problems, difficulty thinking, and making decisions.
They also had at least one additional risk factor for heart diseases, such as high blood pressure (also known as hypertension), high cholesterol, diabetes, or other chronic conditions.
Participants took a number of tests to measure their heart disease risk factors and cognitive ability. Researchers also assessed participants’ dietary habits and ability to perform daily activities.
The participants who were enrolled in the health education group received weekly educational phone calls for three months and then bi-weekly calls for three months.
Phone calls were conducted by a health educator on health topics related to heart disease. Participants were asked to maintain their usual dietary and exercise habits for six months until they were re-evaluated.
At the conclusion of the six-month intervention and assessment, participants were free to engage in whatever activity and dietary habits they desired, with no restrictions.
The results of the research team’s study showed that exercise improved the participants’ ability to think, remember, and make decisions compared to non-exercisers.
And that combining exercise with the Dash diet improved the ability to think, remember, and make decisions, compared to people who didn’t exercise or follow the diet–even though they didn’t perfectly follow the programs they were assigned to during the six-month interventions.
