Yale University, founded in 1701, is one of the world’s leading private research universities located in New Haven, Connecticut. The university maintains a major focus on neuroscience and neurodegenerative disease research through its Yale School of Medicine, Department of Neurology, Department of Neuroscience, and the **Yale Alzheimer’s Disease Research Center (ADRC)**^{1Lecanemab in Early Alzheimer's Disease2023 · N Engl J Med · PMID 36453691Open reference2Blood-based biomarkers for Alzheimer's disease2024 · Lancet Neurol · PMID 38267190Open reference}.

Yale’s neurodegenerative disease research spans the full translational spectrum from fundamental molecular mechanisms through clinical trials, with particular strengths in amyloid and tau biology, neuroinflammation, biomarker development, and therapeutic interventions. The institution has been at the forefront of Alzheimer’s disease research since the establishment of the ADRC in 1984 and continues to lead in understanding disease mechanisms and developing novel treatments

History and Institutional Development

Founding and Early Neuroscience
