If you have this gait, it is an indication that you have Alzheimer’s
Can Alzheimer’s disease be detected simply by observing the way you walk? Researchers have succeeded, with a probability of success of around 70%.
The Alzheimer it is a neurodegenerative disease that develops over the years. The symptoms will appear little by little, the best known being memory loss or tremors in the hands. But there are many others.
Doctors work to detect the onset of Alzheimer’s as early as possible, with the aim of delaying its expansion, since for now it is an incurable disease.
As our colleague Andrea Núñez-Torrón explains in TICbeat, a recent study carried out by scientists from the Lawson Health Research Institute and the Western Schulich School of Medicine and Dentistry, have detected a way of walking that reveals the onset of Alzheimer’s, with a probability of 70%. The study has been published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.
To carry out the tests, the movement patterns of 500 adults were analyzed, from healthy individuals to patients with subjective cognitive impairment, Parkinson’s disease, mild cognitive impairment, Alzheimer’s disease and Lewy body disease.
The researchers studied four independent gait patterns: rhythm, pace, variability and postural control.
Just one of these patterns, gait variability, was associated with cognitive problems. They found that people who showed high variability in gait, that is, that they changed the size or speed of the step randomly, suffered from Alzheimer’s with a 70% success rate.
“This is the first strong evidence to show that gait variability is an important marker for processes that occur in areas of the brain that are linked to both cognitive decline and motor control.”Explains Dr. Federico Perruccini-Faria, one of the authors of the study.
Now the researchers are going to use the study results to develop observational techniques that help detect Alzheimer’s as soon as possible.
Precisely, walking daily and exercising is considered essential to delay the onset of neurodegenerative diseases.
