A decade following the paradigm-shifting concept that endogenous forms of soluble, non-fibrillar amyloid-β (Aβ) might constitute the major bioactive entity causing synaptic loss and cognitive decline in Alzheimer’s disease (AD), our understanding of these oligomeric species still remains conspicuously superficial. The current lack of direct evaluation tools for each endogenous Aβ oligomer hampers our ability to readily address crucial question such as: (i) where they form and accumulate, (ii) when they first appear in human brains and body fluids, (iii) what is the longitudinal expression of these putative toxins during the course of the disease, (iv) how do these soluble Aβ assemblies alter synaptic and neuronal function in the brain. Despite these limitations, indirect ex vivo measurement and isolation from biological specimens have been possible and have allowed parsing out intrinsic differences between putative endogenous Aβ oligomers. In this review, I integrated recent findings and extrapolated on emerging hypotheses derived from these studies with the hope to provide a clarified view on the putative role of endogenous Aβ oligomers in AD, with a particular emphasis on the timing at which these soluble species might act in the aging and diseased brain.
