Sister Mary died at 101 with a brain riddled with Alzheimer’s plaques and tangles, yet she remained cognitively sharp until the end. Scientists studying her case and others like it have finally cracked the biological mystery: the answer lies not in avoiding the disease, but in how the brain’s immune cells contain it.
