A surprising discovery suggests that some early signs of Alzheimer’s disease may begin outside the brain. Using miniature laboratory systems made from human cells, scientists found that genetic mutations associated with inherited Alzheimer’s can disrupt nerve-to-muscle connections without any involvement from the brain or spinal cord. This could help explain why some patients experience changes in balance, walking, and coordination long before memory problems develop.
