Poor physical performance could be an indicator of the development of dementia and Alzheimer's disease among elderly adults, a new report has claimed.
According to findings from researchers at the University of Washington, published in the Archives of Internal Medicine, there could be a significant association between low physical performance and cognitive impairment.
The researchers studied 2,288 people aged over 65 who did not have dementia between the mid-1990s and 2003, testing physical ability and the development of the disease.
It was discovered that with each one point drop on the physical performance scale came a corresponding rise in the risk of dementia and Alzheimer's disease.
"If confirmed, this study might also help explain the association of physical exercise with a reduced risk of dementia, suggesting that exercise, by improving and maintaining physical function, might benefit cognitive function through a connection between the two," the authors of the study concluded.
This may help early intervention to slow down the terrible effects of the illnesses.
