Exercise can help reduce risk of developing dementia

Almost eight in ten people are not exercising enough, despite evidence that regular exercise can reduce a person's risk of dementia, according to a survey conducted by Alzheimer's Society.

Research has suggested that regular exercise could reduce the risk of individuals developing dementia, yet 64 per cent of the people surveyed were unaware of the health and lifestyle benefits associated with regular exercise and physical activity.

Dr Clare Walton, research manager at Alzheimer's Society, said: "The results of Alzheimer's Society's survey are concerning, showing a lack of awareness among the general public of the benefits of exercise. What's good for the heart is good for the head and regular exercise is one of the best ways to reduce your risk of developing dementia, yet many people questioned didn't know that.

"People living with dementia should also try to keep physically active as it can bring many benefits including improved circulation, reduced stress and anxiety and better sleep. Alzheimer's Society's Memory Walks, taking place throughout September are a great way for people with and without dementia to get some exercise and to meet other people in your local community."

The Alzheimer’s Society has revealed that around 225,000 people develop dementia every year, equivalent to one person every three minutes.

NHS guidelines advise adults to take part in at least 150 minutes of moderate aerobic activity every week. Yet, the Alzheimer’s Society survey has found that only 21 per cent of men and 15 per cent of women are following these guidelines, while 14 per cent do not participate in any exercise during an average week.

Furthermore, only 36 per cent of the people surveyed were aware that regular exercise and physical activity can have a significant impact on reducing the risk of developing dementia.

Current evidence suggests that an increase in physical activity, along with increasing cognitive activity, eating a healthy diet, not smoking and management of diseases such as diabetes, have the potential to reduce the risk of dementia. These findings have been reported in several studies including a recent review of dementia risk factors published in the Alzheimer's and Dementia Journal, as well as the World Alzheimer's Report 2014.

Actress Adele Silva will be taking part in Alzheimer's Society's first Memory Walk in Leeds on 5 September 2015. She said: "I've experienced first-hand the devastating effect dementia has on families, and it saddens me to think people aren't aware of simple things they can do to reduce their risk of developing this terrible condition. Evidence has shown that taking regular exercise, eating a healthy balanced diet and not smoking can help prevent dementia and can also help people already living with the condition.

"This Saturday, I'll be taking part in Alzheimer's Society's Leeds Memory Walk and I'll be walking for my wonderful Nan, who had dementia, along with thousands of people walking for their loved ones. It's a great way to raise vital funds to support others living with the condition."

Paul Seymour from Bath was diagnosed with early onset Alzheimer's disease in October 2014 at the age of 54. He commented: "Exercising regularly helps me to wind down and focus my thoughts. I've always been active, but since I was diagnosed with Alzheimer's disease I make an extra effort to get out on my bike or take part in outdoor walking events such as Alzheimer's Society's Memory Walk.

"I'm still young and despite my Alzheimer's diagnosis, I'm determined to stay as active as possible for as long as possible."

Activities such as brisk walking can contribute to the total weekly exercise recommended by the NHS.

Alzheimer's Society's Memory Walks are taking place across England, Wales and Northern Ireland throughout September. To sign up for a walk and begin fundraising, visit memorywalk.org.uk.
