The Cause of Alzheimer's Might Not Be Amyloid

Recent research from Emory University challenges the long-held belief that amyloid-beta deposits are the primary cause of Alzheimer's disease. Instead, scientists suggest that proteins accumulating around these deposits may be responsible for the progression of the disease. The study, published in Cell Reports Medicine, indicates that amyloid-beta serves as a scaffold for other proteins, which could disrupt brain cell function and lead to cognitive decline. Researchers identified over 20 proteins that co-accumulate with amyloid-beta in both human and mouse brains, with two specific proteins, midkine and pleiotrophin, shown to accelerate amyloid aggregation. This new understanding of Alzheimer's pathology suggests that targeting these additional proteins could lead to novel therapeutic approaches. The findings highlight the complexity of Alzheimer's disease, moving away from the simplistic amyloid cascade hypothesis and opening avenues for research into treatment strategies for Alzheimer's and potentially other diseases linked to amyloid buildup.

The tilte is a bit misleading. The cause of Alzteimer's isn't amyloid. This is already known. There are people with high levels of amyloid that show normal cognitive function. There is some other mechanism.

We’ve known for a long time that the cause isn’t amyloid.
