Senile plaques that have been identified consist of both amyloid beta (Aβ40 and Aβ42), whereas the vascular amyloid predominately contains the shorter Aβ40. The exact composition of these plaque types has been debated, but one prominent theory is that senile plaques are not as toxic as other plaque types.
