Poor balance predicts Alzheimer's
A study of 2,288 elderly people found that such physical symptoms were associated with an increased risk of developing dementia.
Researchers from the University of Washington said they believed that exercise could help to stall the progression of the disease.
Their study appears in Archives of Internal Medicine.
Previous research has suggested that exercise may reduce the risk of Alzheimer’s – possibly by boosting blood flow to the brain. Researchers monitored patients every two years for signs of physical and mental decline.
