WebMay 19, 2024 · The most obvious neurological change associated with Alzheimer’s disease is the build-up of toxic amyloid plaques that form outside cells, and tangles of tau proteins within the neurons themselves. WebDifference Between Amyloid and Tau Beta amyloid (amyloid-β) and tau are both proteins synonymous with Alzheimer’s Disease. A clinical picture of an Alzheimer’s patient usually has to do with dead nerve cells and hardened plaques in between them. Within these plaques are proteins that occur in a twisted and tangled manner. In fact, it is these tangles …
