Over the next 8 decades, the scientific community’s knowledge of AD grew, and in 1991, a cogent theory regarding the underlying causative neuropathological processes was proposed. The ACH has since been highly researched, and it has become the most prominent and influential theory regarding a neuropathological cause of AD.

The Development of the Hypothesis

Advances in molecular and genetic research led to the formation of the ACH. One of the first major contributory research ...
