Small changes in the way a person walks may be early signals of memory declines in the brain.
Although some walking difficulty is a common part of the aging process, researchers at the Basel Mobility Center in Basel, Switzerland said pronounced slowing of walking pace or a more variable stride could indicate early signs of cognitive decline.
Their study of more than 1,100 elderly adults showed those with Alzheimer's disease walked much slower than those with mild cognitive impairment, who also walked slower than healthy adults.
The study was presented at the Alzheimer's Association's annual conference over the weekend.
