Amyloid plaques (also known as neuritic plaques, amyloid beta plaques or senile plaques) are extracellular deposits of the amyloid beta (Aβ) protein mainly in the grey matter of the brain. [1][2][3][4] Degenerative neuronal elements and an abundance of microglia and astrocytes can be associated with amyloid plaques.
