Compounds, systems, kits, methods, and / or apparatuses may be operative to reduce amyloid beta (Aβ) peptide in a patient, including a central nervous system (CNS) of the patient and / or a periphery (non-CNS portion) of the patient. In some embodiments, a displacer fluid comprising a Aβ displacer may be introduced to the patient to bind to a blood protein, such as albumin, that binds Aβ (for instance, Aβ peptide or non-plaque Aβ) in the patient periphery. Binding of the displacer to the blood protein may facilitate more free Aβ peptide (for instance, Aβ monomers) in the periphery for clearance via natural processes, such as through the liver or kidneys, and / or artificial processes, such as dialysis. Increased removal of the free Aβ peptide in the periphery may ultimately lead to less Aβ peptide in the CNS, which may decrease Aβ plaque formation in Alzheimer's Disease (AD) patients. Other embodiments are described.
