A study shows that curved path walking can effectively detect early cognitive decline in older adults by analyzing gait impairments, offering a non-invasive, cost-effective tool for early diagnosis and intervention. Credit: SciTechDaily.comA first-of-its-kind study suggests that to detect subtle gait impairments in older adults that often are prevalent in the early stages of cognitive decline, “throw them a curve.
College of Engineering and Computer Science researchers at Florida Atlantic University are the first to quantitatively compare the performance of healthy older adults versus older adults with mild cognitive impairment in straight and curve walking. MCI is the early stage of cognitive decline and people with MCI have a much higher risk of transitioning toMahmoud Seifallahi and Behnaz Ghoraani, Ph.D.
“Intriguingly, curved walking illuminated notable disparities between our study groups, even for these macro gait markers. The MCI group exhibited a markedly lower average step length and speed during curve walking, coupled with higher variability across most micro-gait markers,” said Behnaz Ghoraani, Ph.D.
AD typically manifests as a decline in cognitive function with a gradual decline in an individual’s ability to perform daily activities such as walking. Accurate and early clinical detection of AD remains a challenge. Typical clinical evaluations include a detailed history, comprehensive physical and neurological examination, cognitive testing, blood work, and brain imaging.
