Walking Speed May Predict Dementia Risk, New Study Finds
A recent study suggests that walking speed could be a key indicator of cognitive decline or dementia, offering a simple and accessible screening tool for early detection. The findings, published in JAMA Network Open, highlight how changes in gait and pace may signal underlying cognitive impairments.
Study Overview
Researchers tracked over 16,800 healthy individuals aged 65 and older in the U.S. and Australia between 2010 and 2017. Participants underwent biennial assessments of their walking speed and cognitive abilities.
The study found that individuals whose walking speed slowed by at least two inches per second annually, combined with declining cognitive performance, were more likely to develop dementia. These individuals had a higher risk compared to those with only cognitive or gait-related declines, or no declines at all.
Walking as a Window into Cognitive Health
Dr. Amy Brodtmann, a neurologist and professor at Monash University’s Cognitive Health Initiative in Australia, emphasized the long-held assumption that slowed physical and mental processes can be an early sign of cognitive impairment or dementia.
“The manner in which someone walks—often referred to as their gait pattern—requires coordination, reflexive planning, and focus,” noted Edward Farrell, a physical therapist from Long Island, New York. He explained that these functions are often impaired in individuals with cognitive diseases.
A Simple and Practical Screening Tool
The researchers proposed that monitoring walking speed could serve as a practical tool for identifying individuals at risk of dementia. Dr. Nicole Collyer, a study co-author, suggested that family doctors could incorporate gait measurements into routine evaluations, particularly for patients with concerns about cognitive health.
“Walking speed is simple to measure and could be used alongside other screening tools to ensure timely interventions,” Collyer said.
Broader Implications and Risk Factors
Courtney Kloske, PhD, director of scientific engagement for the Alzheimer’s Association, highlighted the importance of considering additional risk factors, particularly among diverse populations. This research underscores the need for a holistic approach to dementia prevention, incorporating physical, cognitive, and lifestyle factors.
The Importance of Early Detection
As dementia cases continue to rise globally, early detection remains critical in providing timely care and interventions. By identifying potential cognitive decline through walking speed and gait patterns, healthcare providers may be better equipped to combat the progression of dementia.
