Short limbs dementia risk

People with short arms and legs may be at an increased risk of developing dementia later in life, probably as a result of poor nutrition in early life, research suggests.

A five-year study of 2,798 people found women with the shortest arm spans were 50% more likely to develop dementia and Alzheimer's disease than women with longer arm spans. The risk of dementia fell by 16% for every extra inch in leg length. In men, every increased inch in arm span was associated with a 6% fall in risk of dementia.
