Simple Exercise Can Help People with Dementia

A new review of clinical research suggests that simple exercise may benefit older people with dementia.

Exercise works by improving people’s cognitive abilities and enhancing their ability to carry out daily activities.

The study updates a review carried out in 2008, when only four trials on the effects of exercise in older people with dementia were available.

In the updated review, data from eight trials involving 329 people showed that exercise could improve cognitive functioning.

Data from six studies involving 289 people showed that exercise could improve the ability of older people with dementia to carry out daily activities, such as walking short distances or getting up from a chair.

The systematic review is published in The Cochrane Library.

However, the authors of the review say that more evidence is needed to understand how exercise could reduce the burden on family caregivers and health systems.

Dementia affects the brain in different ways and is associated with effects on memory and personality. And as people are living longer, rates of dementia are expected to rise sharply in the coming decades.

It is thought that exercise might be useful in treating dementia or slowing its progression, through improvements in the ability to carry out everyday tasks, and positive effects on mental processes such as memory and attention, collectively described as cognitive functioning.

Exercise may therefore indirectly benefit family caregivers and the health care system by reducing some of the burden of dementia.

“In our previous review, we were unable to draw any conclusions about the effectiveness of exercise in older people with dementia, due to a shortage of appropriate trials,” said researcher Dorothy Forbes.

“Following this new review, we are now able to conclude that there is promising evidence for exercise programs improving cognition and the ability to carry out daily activities. However, we do still need to be cautious about how we interpret these findings.”

The researchers remain cautious because there were substantial differences among the results of individual trials.

In addition, they did not find enough evidence to determine whether exercise improved challenging behaviors or depression in older people with dementia.

They were unable to come to any conclusions regarding quality of life, or benefits for family caregivers and health systems, because there was not enough evidence.

However, the researchers suggest that if more evidence becomes available in future, it may help to address the question of whether exercise can help people with dementia remain at home for longer.

“Clearly, further research is needed to be able to develop best practice guidelines to enable healthcare providers to advise people with dementia living at home or in institutions,” said Forbes.

“We also need to understand what level and intensity of exercise is beneficial for someone with dementia.”
