Physical frailty or weakness among older adults can be an early indicator of the presence of abnormal brain plaque and tangles, all characteristics of Alzheimer's disease pathology, says a new study.
A new study has revealed that physical frailty or weakness among older adults can be an early indicator of the presence of Alzheimer's disease.
The study was conducted over brains of 165 people. While participants were alive, physical frailty measurements were taken yearly including grip strength, time to walk eight feet, body composition and tiredness.

Alzheimer's disease is a progressive neurodegenerative disease affecting memory and thinking and making the person increasingly dependent on others.

The team found that that the level of frailty was nearly two times higher in people with high level of AD pathology.
"Interestingly, Alzheimer's disease pathology was associated with physical frailty in older persons both with and without dementia," said study author Aron S. Buchman, MD, with Rush University Alzheimer's Disease Center in Chicago and member of the American Academy of Neurology.
Early Brain Changes Noticed in Healthy Children of Alzheimer Patients
Healthy children of Alzheimer patients display neurological changes much before clinical symptoms may appear, says Medical College of Wisconsin researchers in Milwaukee.

Previous study on the same group while they were alive showed that eople who are physically frail with no cognitive impairment appear to be at higher risk of developing Alzheimer's disease as compared to those who were less frail.
