Alzheimer’s Spreads Like a Virus in the Brain, Studies Find

• New York Times

The surprising finding answers a longstanding question and has immediate implications for developing treatments, researchers said. And they suspect that other degenerative brain diseases like Parkinson’s may spread in a similar way.
