Alzheimer's linked to muscle weakness

Alzheimer's linked to muscle weakness
13th November 2009

Older individuals with weak muscles may be at increased risk of Alzheimer's disease, according to a new study from Rush University Medical Center in Chicago.

Scientists at the institution noted that the link between muscle strength and the neurodegenerative disorder remained even after other factors were accounted for, such as body mass index and physical activity levels.

Dr Susanne Sorensen, the head of research at the Alzheimer's Society, said that with Alzheimer's disease, changes in the brain may begin many years before a person begins to develop dementia symptoms, though the organisation also highlights how the body may be altered.

She continued: "Observation of increasing muscle weakness may serve as one of the indicators that could alert GPs to the need for a cognitive assessment.

"More research is needed before we can fully understand what causes dementia. One million people will develop dementia in the next ten years. We must act now."
