In normal adults, walking 6 miles a week instead of being sedentary was associated with a 50% reduction in Alzheimer’s risk over a 13 year study.
As shown by MRI, brain volume was preserved in healthy adults who walked at least 6 miles per week.
Walking more than 6 miles a week offered no additional benefit.
The association between walking and the reduction in risk persisted even after the analysis was adjusted to take into account other risk factors for dementia including age, gender, and high blood pressure.
This is exciting news because it’s something we can do something about. This translates to about 17 minutes of walking a day or 40 minutes of walking three times a week. It can be outdoors or on a treadmill.
It’s never too late to start!
