Headache or mild fatigue reported in a subset of subjects
This review integrates current evidence on how brain peptides contribute to AD pathophysiology, summarizes recent progress in peptide-based therapeutic strategies and delivery platforms, and critically examines the remaining barriers to clinical translation, including bloodbrain barrier penetration, metabolic stability, off-target effects, and the need for biomarker-guided patient stratification
