a(HBP:"amyloid-beta oligomers") association path(HBP:neurotoxicity)
Early work on AD considered the fibrillar form to be the toxic species. However, a lack of correlation between plaque burden and cognitive score contrasted with a strong positive correlation between total soluble amyloid and cognitive decline pointing to soluble, oligomeric forms as the primary toxic factor (Walsh and Selkoe, 2007).
