Walking Speed Could Indicate Dementia


How fast (or slow) you walk could shed light on your odds of developing dementia or mild cognitive decline later in life, recent research has suggested.
Scientists from Oregon Health and Science University made the potentially useful link between walking speed and poor mental health, after studying both the cognitive decline and walking style of 93 elderly participants.
Out of the volunteers, 54 has no signs of cognitive decline, 31 had non-memory-related memory decline and 8 had memory-loss related cognitive decline.
The participants from the study (all aged 70 and over) had their walking speed monitored using infrared sensors in their homes over a three-year period. They were also given regular memory and thinking tests.
Researchers discovered that those people who walked slowly were nine time more likely to develop non-memory-related mild cognitive decline (MCI) than those who were moderate to fast walkers.

“Further studies need to be done using larger groups of participants to determine whether walking speed and its fluctuations could be a predictor of future memory and thinking problems in the elderly,” study author Dr Hiroko Dodge, said in a statement.
“The research is important as it could help detect dementia in the early stages and also help in preventing the disease from developing. Our in-home monitoring approach has a lot of potential to be used for sustaining independence of the elderly," Dodge added.
The study was published in the American Academy of Neurology.
Dr Marie Janson, Director of Development at Alzheimer’s Research UK, told HuffPost Lifestyle: "Although this study has yet to be published in full, it does raise some important questions about whether physical problems, such as difficulty walking, could precede other symptoms associated with dementia.”
"It's not clear whether the people in this study had other health problems that may have affected their walking speed, and which could also raise the risk of dementia – however further study could shed new insight into how walking speed and dementia may be linked.
“Currently 820,000 people are affected by dementia in the UK, and as our population ages that number is increasing. We still need a better understanding of the causes of dementia if we are to find effective ways to treat and prevent the condition, and that means we must invest in research."

This isn’t the first time scientists have found a link between slow walking and poor health. In 2009, a team of researchers discovered a strong association between the speed of someone’s walk and their chances of developing heart disease.
Another study, published in theJournal of the American Medical Association, discovered a link between fast walking in elderly people and living a longer life.
