Dementia

This Could Be a Sign Of On-Setting Dementia

This Could Be a Sign Of On-Setting Dementia. Walking more slowly with age has always been a warning sign of increasing frailty, which can lead to falls and other disabilities, according to experts. Emerging research in small groups of elderly participants suggests that a slower gait from one year to the next may be an early indicator of cognitive decline.

How to burn the most calories when walking

According to studies, this may be the result of a reduction in the right hippocampus, the region of the brain associated with memory.

According to the National Institute on Aging, only 10 to 20 percent of 65-year-olds or older with mild cognitive impairment or MCI develop dementia within the following year. In many cases, the symptoms of MCI may remain unchanged or even improve, according to the institute.

Now, according to a large, recent study of nearly 17,000 adults over the age of 65, those who walk at least 5 percent slower each year and show signs of slower mental processing are most likely to develop dementia. The research was published in the journal JAMA Network Open on Tuesday.

“These results highlight the importance of gait in assessing dementia risk,” wrote Taya Collyer, a research fellow at the Peninsula Clinical School of Monash University in Victoria, Australia, and the corresponding author.

“Dual decliners” are most at risk

Monitor exercise intensity with the “talk test”

The ‘talk test’ measures the intensity of physical activity.

A new seven-year study followed a group of Americans over 65 and Australians over 70. Participants in the study were required to take cognitive tests every other year to measure cognitive decline, memory, processing speed, and verbal fluency.

The participants were also asked to walk 3 meters, or approximately 10 feet, twice every other year. The average of the two results was then used to determine the individual’s typical gait.

Dr. Joe Verghese, a professor of geriatrics and neurology at the Albert Einstein College of Medicine in Bronx, New York, who was not involved in the study, said “dual decliners” had the highest risk of dementia. “Dual decliners” were individuals who not only walked more sluggishly but also exhibited signs of cognitive decline.

“Furthermore, dual decliners had a higher risk of dementia than those with gait or cognitive decline alone,” Verghese wrote in an editorial accompanying the study published Tuesday in the JAMA journal.

According to studies, a slower gait as you age may be an indicator of future dementia.

A 2020 meta-analysis of nearly 9,000 American adults found that a dual association between walking speed and memory loss is predictive of future dementia.

Verghese wrote that despite these findings, “gait dysfunction has not been considered an early clinical feature of Alzheimer’s disease.”

Physical activity may help.

There are things we can do as we age to reverse the natural brain atrophy that occurs with aging. According to studies, aerobic exercise increases the size of the hippocampus, which improves certain aspects of memory.

The hippocampus, a peculiarly shaped organ buried deep in the temporal lobe of the brain, is responsible for learning, consolidating memories, and spatial navigation, such as the ability to remember directions, locations, and orientations.

Even if you show signs of dementia, physical activity may protect your brain, according to a study.

In a 2011 randomized clinical trial, aerobic exercise training increased the volume of the right anterior hippocampus by 2 percent, thus reversing the age-related loss in the organ by one to two years. Comparatively, people who only performed stretching exercises experienced a decline of approximately 1.43 percent over the same time period.

Aerobic exercise is a type of workout in which your heart rate and breathing increase, but not to the point where you cannot continue to function. Aerobic exercises include brisk walking, swimming, running, cycling, dancing, and kickboxing, as well as all the cardio machines at your local gym, such as the treadmill, elliptical trainer, rowing machine, and stair climber.
