Alzheimer's may start in one area of the brain and involve a special protein called the "tau" which propagates
Recent research suggests that Alzeheimer’s disease may start in one area of the brain and spread through synapses by cell-to-cell movement of a “tau” protein. Previously the disease had been thought to be multifocal. This model suggests what is already known for a few diseases like “Mad Cow” where an “infectious protein” changes the geometry of cells it contacts and propagates. New medications could target the tau protein as well as the amyloid. But the story also presents the disease as a sort of pseudo-malignancy.
