A team of Brisbane-based researchers say you can help ward off dementia and other brain conditions in just ten minutes each day.

The key, they believe, is 60-second bursts of activity followed by at least 10 minutes of rest.

"Brain blood flow steadily decreases with older age and that's linked to risk of cardiovascular disease such as stroke and cognitive decline including risk of dementia," explained University of Queensland researcher Tom Bailey.

Researchers found that in older adults, interval training promotes brain flow more than continuous exercise. For example, they say during a walk, adults should incorporate walking up some stairs or a small hill into their routine.

Additionally, another study by the Alzheimer’s Society found that senior participants who were in the bottom 10 percent in terms of amount of daily physical activity were more than twice as likely to develop Alzheimer's disease as those in the top 10 per cent.

Researchers are continually trying to determine what type of physical activity is best for dementia prevention.
