Johns Hopkins scientists have uncovered hidden warning signs of Alzheimer’s disease that may appear up to a decade before memory loss begins. Brain scans revealed that two regions involved in memory and emotion start shrinking before the hippocampus, the area doctors typically examine for signs of Alzheimer’s. These early changes are linked to abnormal tau protein buildup and could provide a powerful new way to identify people at risk.

Alzheimer’s may have early warning signs outside the brain

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 connection

Evolution found another way to build a primate brain

What makes the human brain so much larger and more complex than the brains of many other mammals? Scientists have long sought clues in our DNA. Some discoveries show how genetic changes enable the developing brain to produce more cells. Others help explain how long those cells ca
