A mild cognitive impairment (LCC) is characterized by a slight loss of cognitive abilities, such as memory and reasoning. A person with CCL may have difficulty remembering things, making decisions, or focusing on tasks.
Although cognitive impairment is not serious enough to interfere with daily activities, it increases the risk of Alzheimer's disease and other forms of dementia. New research suggests that there may be a way to address these age-related cognitive issues. The participants included in the study were sedentary at first. They had cardiovascular risk factors and reported symptoms of CDC.
Participants followed the DASH diet (Dietary Approaches to Stop Hypertension). The DASH diet includes foods high in fiber and low in sodium, such as fruits, vegetables, nuts, beans, cereals and lean meat, as well as low-fat dairy products. The researchers divided the participants into four groups: one group only did aerobic exercises, another followed the DASH diet (without any exercise), another did exercise and adopted the DASH diet and another received telephone calls concerning health
. 3 sessions per week of 45 minutes, including warm-up exercises followed by walking, running or cycling. The new study revealed an average 5-point increase in executive skills among people who exercise and dieting compared to those who only exercise or who just follow a diet.
Executive function is the cognitive ability that allows a person to plan and organize actions directed toward an objective, as well as the concentration and regulation of his behavior.
The principal investigator explains that the scores of the executive functions of the participants were, at the beginning of the study, equivalent to those of 93 years, although the chronological age was lower than 28 years . However, after 6 months of supplemental exercise, the average score corresponds to that of 84-year-olds, which equates to an improvement in executive function over 9 years.
