Part of the issue is the vagueness is likely appropriate to both as we don't know the depth. It is linked to Alzheimer's and its presence causes a negative effect so it is contextually a toxin at least until narrowed down to a more precise mechanism like say prions, inappropriate cell reactions, and/or inappropriate oxidation levels. Anyway that amateur explanation aside - the woo community is inherently appropriative of things they don't understand - witness "quantum" anything buzzwords outside of the physics or numerical context.
