The Weird Link Between Walking Speed and Cognitive Decline
Have you ever noticed how some people walk faster or slower than others? It might seem like a simple matter of physical fitness, but recent research suggests that walking speed could be linked to something much more complex: cognitive decline. Cognitive decline refers to a reduction in mental abilities such as memory, thinking, and problem-solving, often associated with conditions like dementia.
### What Does the Research Say?
A study from Monash University in Australia found that people who walk slowly and have weak grip strength are more likely to experience cognitive decline and even develop dementia. This study tracked over 18,000 healthy individuals aged 70 and older for five years. The results showed that those with slower walking speeds and weaker grip strength faced a significant increase in dementia risk—up to 89%—and a higher likelihood of cognitive decline—up to 55%[1].
Another study highlighted that slower walking speeds are often seen in people with cognitive impairment. This research used cameras to track movement and found that individuals with lower cognitive function tend to walk more slowly, especially at higher speeds[3]. Additionally, a multicohort study involving over 1,500 participants found that reduced gait speed can precede cognitive decline by up to a decade[5].
### Why Is Walking Speed Important?
Walking speed is not just about physical health; it can also reflect underlying brain health. Changes in gait, or the way we walk, can signal issues in the brain that affect cognitive functions. For instance, slower walking speeds have been linked to an increased risk of mortality, particularly from cardiovascular diseases[5].
### What Can You Do?
While a slower walking speed might not always indicate cognitive decline—other factors like injuries or medications can also affect gait—it’s important to monitor changes in your walking speed. If you notice a significant change, it might be worth discussing with a healthcare provider. Early detection of cognitive decline can help manage symptoms and slow progression.
Incorporating regular physical activity, maintaining a healthy lifestyle, and staying mentally active can also help support overall brain health. By understanding the connection between walking speed and cognitive decline, we can take proactive steps to protect our mental and physical well-being as we age.
