Decades of Alzheimer's Research Focused on Amyloid Now Questioned as Potential Blind Alley

Scientists are reassessing decades of Alzheimer's disease research that has concentrated heavily on amyloid proteins, with growing concerns that this focus may have been a misguided approach. The amyloid hypothesis, which has dominated Alzheimer's research and drug development for years, posits that accumulations of amyloid-beta proteins in the brain are a primary cause of the disease. However, mounting evidence suggests this pathway may not be the key driver of cognitive decline that researchers once believed, potentially representing what some now characterize as a "blind alley" in the search for effective treatments.
