GLP-1 receptor agonists for Alzheimer’s disease: Lessons from trials and translational challenges

Abstract

Alzheimer’s disease (AD) is a multifactorial disorder that requires combined therapeutic strategies beyond amyloid clearance. Although GLP-1 receptor agonists show strong mechanistic rationale and supportive epidemiological signals for neuroprotection, large randomized trials in symptomatic AD have yielded negative clinical outcomes and do not support the therapeutic use in AD.
