Alzheimer’s isn’t a prion disease, but it does show prion-like behavior. Misfolded proteins like amyloid-beta and tau can spread within the brain similarly to prions, but unlike true prion diseases (e.g. CJD), Alzheimer’s isn’t infectious and isn’t caused by prions. It's a distinct neurodegenerative disorder with overlapping mechanisms, not classification.
