Scientists May Have Found What Really Triggers Alzheimer’s Disease

Scientists may have uncovered a hidden trigger behind Alzheimer’s disease. Instead of plaques being the root cause, amyloid beta appears to interfere with tau, a protein that helps keep neurons functioning properly. This disruption could set off the damage that eventually leads to the disease’s most recognizable brain changes.
