Research Question

"There's a clear disconnect between improved mechanistic understanding of AD and therapeutic success, with continued phase 3 trial failures. This translation gap suggests fundamental flaws in target selection, trial design, or disease model assumptions that need resolution. Gap type: contradiction Source paper: Alzheimer Disease: An Update on Pathobiology and Treatment Strategies. (2019, Cell, PMID:31564456)"
