Comparing Gait Parameters Can Predict Decline in Memory, Thinking

I had a significant decline in gait post-stroke. Does that predict my decline in memory and thinking? My gait is still off 10 years later. The same study should have included abnormal participants like stroke and TBI survivors, like the real world contains rather than these cherry picked participants.

A study published in the Journal of Alzheimer's Disease found that problems associated with gait can predict a significant decline in memory and thinking.
Using the Rochester Epidemiology Project, researchers from the Mayo Clinic, Rochester, Minnesota, examined medical records of residents from Olmsted County, Minnesota, who were aged between 70 and 89 as of October 1, 2004.
The analysis included 3,426 cognitively normal participants enrolled in the Mayo Clinic Study of Aging who had a complete gait and neuropsychological assessment.
At baseline and every 15 months (mean follow-up, 1.93 years), participants had a study coordinator evaluation, neurological examination, and a neuropsychological assessment using 9 tests that covered 4 domains. Gait parameters were assessed with the GAITRite instrument.
Spatial (stride length), temporal (ambulatory time, gait speed, step count, cadence, double support time), and spatiotemporal (cadence) gait parameters, and greater intraindividual variability in stride length, swing time, and stance time were associated with a significant decline in global cognition and in specific domains including memory, executive function, visuospatial, and language.
The results of the study also support the role of computerised analysis because the computer tool detected modifications before impairment was detected with a standard neuropsychological test.
“The presence of gait disturbances increases with advancing age and affects the independence of daily living, especially in the elderly,” said lead author Rodolfo Savica, MD, Mayo Clinic. “Computerised gait analysis is a simple, noninvasive test that potentially could be used to identify patients at high risk for cognitive decline and to target appropriate therapies.”
