Aerobic exercises may boost cognitive skills, delay Alzheimer’s

Engaging in aerobic exercises such as spinning, running, walking may be three times more effective than other types of exercise in delaying the risk of Alzheimer’s disease as well as improving cognitive function in older adults, a study has found. Alzheimer’s disease — the most common form of dementia — is a brain disorder that destroys memory and thinking skills over time in older adults. There is presently no cure for the condition, though treatment options are available.

The findings, led by Gregory A. Panza, Exercise Physiologist at the University of Connecticut, showed that older adults at risk for or who have Alzheimer’s, who did aerobic exercise by itself experienced a three times greater level of improvement in their ability to think and make decisions than those who participated in combined aerobic training and strength training exercises. Older adults in the non-exercise group faced declines in cognitive function.

However, those who exercised showed small improvements in cognitive function no matter what type of exercise they did, the researchers said. Geriatrics experts have for long suggested that exercising can improve brain health in older adults. The World Health Organization (WHO) has recommended that older adults perform 150 minutes a week of moderate exercise (such as brisk walking), 75 minutes a week of vigorous aerobic training, or a combination of the two types. The WHO also suggested older adults perform muscle-strengthening exercises on at least two or more days a week.

For the study, published in the Journal of the American Geriatrics Society, the team reviewed 19 studies involving 1,145 older adults that examined the effect of an exercise training programme on cognitive function in the elderly at risk for or diagnosed with Alzheimer’s. Of the participants, in their mid-to late 70s, 65 per cent were at risk for Alzheimer’s and 35 per cent had been diagnosed with Alzheimer’s.

Manage risk factors to delay Alzheimer’s

With the exponentially growing elderly population worldwide, the number of people with dementia is also rising, warranting the need for more trained caregivers to support them. With changing demographics, one wonders if schools will one day get converted into elderly day-care centres.
