RELATED: If You Can’t Hear While Doing This, Your Dementia Risk Is 91 Percent Higher. In a 2018 study published in the Journal of the American Geriatrics Society in March 2018, a team of researchers from the University College London and University of Nottingham analyzed data collected from 3,932 adults older than 60 who had participated in the English Longitudinal Study of Aging. The team first recorded the participants’ walking speeds on two separate occasions sometime between 2002 and 2003 and again in 2004 to 2005. They then followed up by performing annual assessments with participants between 2006 and 2015 to see if any had been diagnosed with dementia. The researchers then compared walking speed with results from the annual follow-ups and found that there was an increase in dementia diagnoses among participants who clocked slower walking speeds. Results also showed that those who showed a more significant decrease in walking speed between the testing periods were even more likely to have ultimately been diagnosed with the degenerative disease. Besides not walking quickly, the researchers also found that being slow in another way was an indicator of high dementia risk. Results showed that participants who performed more slowly during cognitive and decision-making tests at the beginning of the study were also more likely to be diagnosed eventually. And similarly to a slowing pace, those who showed a decline in decision-making speed between testing sessions were at an even higher risk of dementia.

Ultimately, the researchers concluded that both older adults with slower walking speeds and those who showed a slowing down are at an increased risk for dementia. But the team stopped short of concluding that a decline in walking speed was responsible for a subsequent slowing of cognitive function in participants, saying that further research was needed to establish a connection between the two.ae0fcc31ae342fd3a1346ebb1f342fcb For more helpful health information sent straight to your inbox, sign up for our daily newsletter. But it’s not just your pace that could be a warning sign about your brain health. A 2012 study published in Gait & Posture analyzed the arm movements of Parkinson’s patients who were in the early stages of the disease. Penn State researchers attached accelerometers to the arms of eight patients and eight people of similar age and sex who did not have Parkinson’s disease. They then observed them as they walked continuously for around eight minutes at a comfortable pace. The results showed that those with Parkinson’s had a significantly higher rate of arm swing asymmetry when walking—meaning one arm swung substantially less than the other. “In other words, if I measure the location of your right arm, it is difficult to use that measurement to predict the location of your left arm,” study co-author Joseph Cusumano, PhD, professor of engineering science and mechanics at Penn State, said in a statement. “It is well known that Parkinson’s disease has an impact on how people move … but here we are for the first time precisely quantifying how the disease not only affects the relative amount of limb movements, but also how well coordinated in time these movements are.” RELATED: If You’re Driving Like This, It Could Be an Early Alzheimer’s Sign, Study Says.
