Abstract
The approvals of the first anti-amyloid antibodies for the treatment of Alzheimer's disease have changed both the clinical and research landscape for the disease. These antibodies, lecanemab and donanemab, mark a turning point for our understanding of the disease pathogenesis and for the treatment of this prevalent disorder. This review discusses what they imply for disease pathogenesis and what is needed to progress from the current imperfect therapies toward safe and better, disease halting therapies. The research over the next period will involve drug development, largely aimed at reducing the side effects of the anti-amyloid therapies, biomarker and genetic research to try and identify patients earlier in the disease process, and neuropathological research in individuals who have received treatment to try and understand the pathological substrates of the continuing clinical decline in the disease.
