For decades, researchers have recognized that Alzheimer’s disease is marked by the buildup of toxic protein fragments in the brain. What has remained unclear is exactly how and where those harmful fragments are generated.
In a new study, scientists at Northwestern University report that they have identified both the location and timing of this toxic buildup in Alzheimer’s patients. The team also found that an inexpensive drug already approved by the Food and Drug Administration (FDA) can interrupt the process before the damage begins.
