What if the way you walk could predict the future of your brain health? Researchers are uncovering a surprising connection between walking speed, memory, and the risk of dementia. This isn’t just about mobility—it’s about an early warning system for cognitive decline. Could your everyday steps hold the key to protecting your brain and extending your mental vitality? Dive into the research to discover how something as simple as walking might reveal critical insights into your long-term health.
Key Takeaways
- A slower walking speed in older adults correlates with a higher risk of developing dementia.
- Combined slower walking speed and memory decline increase dementia risk more than sixfold.
- Regular exercise and a healthy diet, such as the Mediterranean diet, can help reduce the risk of dementia and other cognitive issues.
Predicting Alzheimer's Disease
For quite a while, researchers have been searching for ways to accurately predict your chance of developing Alzheimer's disease or one of the other forms of memory-robbing dementia.
The sooner you know your brain is in danger, the more motivated you might be to make lifestyle changes to shore up your brain health.
What’s more, an early warning also gives you more time to prepare for any physical, emotional, or financial consequences of suffering from severe memory loss.
Now, studies show there are two changes in your physical and mental health that, taken together, might be the kind of “your brain is in danger” sign that medical researchers have been looking for.
What Your Steps Say About Your Memory Health
If your walking speed starts to slow as you age, your chances of succumbing to dementia are likely speeding up. Several studies have revealed this unusual phenomenon.
For example, researchers in England analyzed changes in walking speed in older people by examining data collected during a study called the English Longitudinal Study of Aging.
During this study, researchers analyzed the walking speeds of people aged 60 and older between the years 2002 and 2003 and then again in 2004 to 2005. For the next nine years, between 2006 and 2015, researchers evaluated participants' cognitive abilities and compared them with changes in their walking speeds.
Of the 4,000 people in the study, those who had slower walking speeds were found to be at greater risk of dementia.1 Additionally, the folks whose walking speed slowed down the most during the initial two-year test period had the highest risk of Alzheimer's and other types of dementia.
The researchers also discovered that people who had a reduced ability to think and make decisions at the start of the study and whose thinking abilities most quickly declined throughout the study also had a greater chance of dementia.
This Double Deficit Increases Your Risk of Dementia More than Six Times
There’s more evidence. An analysis of six different studies involving about 8,700 people shows that if you’re over 60 years old and your walking speed slows down at the same time as you begin to suffer from memory problems, your risk for dementia is multiplied by more than six times.2
This meta-analysis, coordinated by researchers at the National Institutes of Aging in Baltimore, took a close look at studies performed in Europe between 1997 and 2018 to determine dementia risk. Furthermore, from this study—and other evidence—the researchers conclude that if you’re suffering from slower mobility at the same time your mental recall is shrinking, you should undertake an intensive preventive program of lifestyle changes to give yourself a fighting chance of avoiding dementia.
Researcher Manuel Montero-Odasso, of the University of Western Ontario in Canada, recommends incorporating exercise and replacing junk food with more fruits and vegetables for an effective dementia prevention lifestyle. Dr. Montero-Odasso says there’s no reason to wait, "in light of emerging evidence that lifestyle interventions -- such as physical exercise, incorporating Mediterranean diets, or intensive blood pressure control -- may help delay progression to dementia in older adults at risk."3
Walking Speed Can Also Predict Depression
According to a study in Ireland, another potential use of measuring walking speed in older people is to diagnose depression in its early stages. The research shows that a significant slowdown can indicate the presence of mood problems that might require medical intervention.
Irish scientists believe measuring walking speed might make it easier to diagnose depression in seniors, a notoriously tricky population for identifying depression.4
For one thing, older people are often unwilling to discuss their feelings. Many times, their depression shows up as excessive fatigue, trouble sleeping, and irritability. Plus, they may seem confused and inattentive due to depression—and these symptoms may be mistaken for Alzheimer's or some other neurological disorder.5
One thing all of these researchers agree on is the need to keep exercising at any age. Brisk walking every day—or walking as fast as you feel comfortable—may improve your fitness, mood, and mental capacity. Walking will also improve your heart health, and walking might even stretch your longevity!
Summary
New research reveals a startling link between walking speed and dementia risk. Studies show that older adults with slower walking speeds and declining memory face a sixfold increase in their likelihood of developing dementia. This "double deficit" highlights the importance of early intervention, including exercise and diet changes, to stave off cognitive decline. Moreover, walking speed can also help identify other health risks like depression, emphasizing the need for regular physical activity to boost mood, memory, and longevity.
Frequently Asked Questions
