Brigham and Women's Hospital

Overview

Mermaid diagram (expand to render)

Brigham and Women's Hospital (BWH) is a premier teaching hospital of Harvard Medical School, located in Boston, Massachusetts. Founded in 1914 through the merger of Peter Bent Brigham Hospital and other predecessor institutions, BWH has become a world-renowned center for medical research and clinical care, with significant programs in neuroscience and neurodegenerative disease research["@brigham"].

The hospital's Department of Neurology conducts comprehensive research on Alzheimer's disease, Parkinson's disease, and other neurodegenerative conditions, with unique expertise in understanding sex differences in neurodegeneration and women's brain health. BWH researchers have made fundamental discoveries in disease mechanisms and developed novel therapeutic approaches["@bwh_neuro"].

Brigham and Women's Hospital is part of Mass General Brigham, the largest health care system in New England, which provides seamless access to cutting-edge research across multiple academic medical centers. This integration enables BWH to serve as a hub for neurodegenerative disease research, connecting basic science discoveries with clinical implementation.

History and Development

BWH has a long history of medical innovation that has shaped its current status as a leader in neurodegenerative disease research:

1914: Founded through merger of Peter Bent Brigham Hospital, Boston Lying-In Hospital, and other institutions
1930s: Establishment of early neurology research programs
1970s: Development of comprehensive neurology department with subspecialty focus
1980s: Pioneering work in amyloid biology and Alzheimer's disease mechanisms
1990s: Creation of specialized dementia research programs and memory disorders clinic
2000s: Founding of Ann Romney Center for Neurologic Diseases
2010s: Launch of Women's Brain Initiative and integration of precision medicine
2020s: Leadership in anti-amyloid antibody clinical trials and biomarker-driven prevention

The history of BWH is closely tied to the broader Harvard neuroscience community. Researchers at BWH, particularly in the Department of Neurology, have been central to the evolution of the amyloid hypothesis of Alzheimer's disease since the late 1980s[@selkoe1992].
