CaixaResearch Snapshot: Amyloid beta, a key factor as from the early stages of Alzheimer’s
Published on 11/03/2025

Alzheimer’s is the most common cause of dementia and, despite its huge impact, there’s still no effective cure. Its impact on society is huge and it has been calculated that, by 2050, the number of cases of Alzheimer’s will have tripled, rising from the current 1.2 cases in Spain to 3.6 million. As the disease advances, there’s progressive neurodegeneration that affects not only memory but also the ability to relate to others and even the individual’s own identity.
For years, it was believed that the brain damage associated with Alzheimer’s, especially in the regions essential for memory, only occurred when two proteins were present: amyloid beta and tau. However, this hypothesis could be about to change.
