Falls more common in elderly with cognitive impairment
Manuel Montero-Odasso, M.D., Ph.D., from the University of Western Ontario in London, Canada, and colleagues conducted a literature review of observational and interventional studies to assess the relationship between gait and cognition in aging and neurodegeneration.
The researchers found that low performance in attention and executive function is associated with gait slowing, instability, and future falls. In Parkinson's disease, drug enhancement of cognition may reduce falls. To improve mobility in sedentary older adults and in those with cognitive impairment and dementia, cognitive training, dual-task training, and virtual reality modalities are promising.
"Disentangling the mechanism and contribution of cognitive deficits in fall risk may open new treatment approaches. Mounting evidence supports that cognitive therapies help reduce falls," the authors write.
