The early stages of Alzheimer’s disease are preceded by rising levels of amyloid-β in the brain. This may be due to impaired drainage of cerebrospinal fluid, chronic infection by persistent pathogens, or other mechanisms. Since amyloid-β can be exported from the brain into the bloodstream, and since there is a dynamic equilibrium between levels in the two locations, it is in principle possible for…
