Physical frailty in the elderly may be an early symptom of Alzheimer's. A group of neurological scientists at Chicago's Rush University Medical Center say that it turns out physical frailty and Alzheimer's may not be directly linked but stem from a common origin. The team based their findings on brain autopsies of deceased elderly patients.
Patients whose brains showed high levels of Alzheimer's development had been twice as physically frail as those with lower levels of Alzheimer's progression.
This was true regardless of whether a patient had experienced dementia or not. The results also held up regardless of a patient's physical activity level or disease history.
