Profile for Brain Disease Research Infrastructure for Data Gathering and Exploration (BRIDGE) Platform

Area of Science:

• Neuroscience
• Public Health
• Biomedical Informatics

Background:

• Brain diseases present complex research challenges due to limitations in existing registries, including incomplete data, lack of standardization, and poor integration.
• Current registries often lack comprehensive variable sets, standardized data collection, and linkage to external health databases, hindering in-depth research and prevention strategies.

Purpose of the Study:

• To introduce the Brain disease Research Infrastructure for Data Gathering and Exploration (BRIDGE), a national prospective platform designed to overcome the limitations of existing brain disease registries.
• To establish a standardized, comprehensive, and linked database for brain disease research, facilitating a deeper understanding and improved management of neurological conditions.

Main Methods:

• The BRIDGE platform integrates multiple cohorts: Longitudinal Study of Early onset dementia And Family members (LEAF), Longitudinal/cohort Study of Patients with Late Onset Dementia (LLOD), community-based High-risk individuals for Dementia (COHD), and Longitudinal Study of Patients with Parkinson's Disease (LoPD).
• Standardized data collection includes sociodemographics, health behaviors, medical history, functional status, cognitive function, disease-specific symptoms, quality of life, sleep, mood, caregiver burden, physical health, and various biomarkers (blood tests, genetic testing, neuroimaging).
• The platform is designed for linkage with the Korean National Health Insurance Service (K-NHIS) database to enable comprehensive data analysis.

Main Results:

• The BRIDGE platform establishes a standardized, prospective national database for brain diseases, encompassing diverse cohorts and extensive variable sets.
• Integration of multiple data types, including clinical, behavioral, genetic, and imaging data, alongside linkage to national health insurance data, provides a rich resource for research.
• The platform addresses critical gaps in data standardization, continuity, and integration, offering a robust infrastructure for brain disease research.

Conclusions:

• The BRIDGE platform represents a significant advancement in brain disease research infrastructure, offering a comprehensive and standardized resource for understanding complex neurological conditions.
• By overcoming limitations of previous registries, BRIDGE provides new pathways for scientific discovery, improved treatment strategies, and informed policymaking in brain health.
• The prospective nature and extensive data collection of the BRIDGE platform are expected to significantly influence future research and public health initiatives in neurodegenerative diseases.
