Thank you for commenting and pointing out that similarity. Amyloid buildups are indeed a consequence of something, which I referred to as trigger(s). Cholesterol and amyloid are something our body produces, typically in response to a need or biological function.

It's also true that some people have a lot of amyloid plaques in their brains but are cognitively healthy. Scientists think this is because they have good cognitive reserve from protective factors like high education, mental stimulation, and active social life.
