Dementia is a group of symptoms associated with a progressive decrease in brain function. The most common type of dementia in the UK is Alzheimer's disease. This can lead to a number of problems, including memory loss, difficulty understanding speech, mood swings and difficulty moving. But you could lower your risk of dementia later in life through exercise, the NHS said. It is best to avoid the development of dementia symptoms by performing your recommended 150 minutes of moderate intensity activity every week.
Regular exercise could lower the risk of heart disease, type 2 diabetes and obesity. These are risk factors for dementia.
It is recommended that everyone do aerobic activity at medium intensity every week for 150 minutes.
The best examples of aerobic activity are walking, cycling, swimming or dancing.
"There is no specific way to prevent all types of dementia, and researchers are still investigating how the disease develops," the NHS said.
"However, there is good evidence that a healthy lifestyle can help reduce the risk of dementia as you get older.
"Lack of regular physical activity can increase the risk of heart disease, overweight or obesity, and type 2 diabetes – all risk factors for dementia.
"Older adults who are not moving also have more frequent memory or thinking problems [known as cognitive abilities],
"Follow the recommended guidelines for 150 minutes of moderate intensity aerobic activity per week, such as brisk walking, cycling, or dancing."
Everyone should also try strengthening exercises twice a week. That could be gardening or yoga.
It is also important that everyone wants to spend less time sitting down, he added.
Try to get up regularly and walk around.
An easy way to do this is to take the stairs instead of an escalator or to talk on the phone while standing.
According to the Alzheimer's Society, around 850,000 people in the UK live with dementia.
All dementia sufferers have different symptoms and everyone will experience these symptoms differently.
The most common early warning signs of dementia include memory loss, difficulty concentrating, and difficulty in performing everyday tasks.
When the condition develops, it can lead to communication problems, incontinence, mobility issues, and weight loss.
One in fourteen over 65 year olds will suffer from dementia sometime in his life, while one in six over 80 year olds has dementia.
