It was also demonstrated that fibril-free AβO solutions are essential for memory loss (Brito-Moreira et al. 2017), while the fibrillar Aβ in amyloid deposits is not the active factor affecting the cognition (Martins et al. 2008). PubMed:29196815

In addition, the load of AβO deposits significantly correlated with fibrillar Aβ plaque deposition as well as with neuronal loss and numbers of astrocytes, although not with memory deficits. PubMed:29196815

The histopathological changes in the brain include the presence of extracellular amyloid plaques consisted of various peptide variants of amyloid β (Aβ) and accumulation of intracellular neurofibrillary tangles (NFTs) composed mainly of phosphorylated Tau proteins (pTau), localized predominantly in neurons (reviewed by Serrano-Pozo et al. 2011).

Amyloid hypothesis is supported by the fact that progressive Aβ deposition is observed in early, preclinical stages of AD and, finally, in all AD patients. PubMed:29196815
