Early Alzheimer's symptoms may develop outside the brain

Scientists have found that early signs of Alzheimer's disease can develop outside the brain – genetic mutations linked to the hereditary form of the disease disrupt nerve-muscle connections without involving the brain or spinal cord. The study was conducted on miniature laboratory models built from human cells. The discovery may explain why some patients experience balance and walking problems long before memory problems appear.
