UK Biobank is a major national health resource designed to improve the prevention, diagnosis
and treatment of a wide range of illnesses
Why is Biobank special?
• Very large size (n=503,000)
–1000s of disease cases for adequately powered case-
control and case-cohort studies
• Extensive and detailed exposure measures
• Comprehensive follow-up
linkage to a wide range of health-related records
questionnaires
detailed phenotyping of outcomes
• Open access resource: see www.ukbiobank.ac.uk
Automated sample archive
• Blood
whole blood
serum
plasma
red cells
buffy coat
• Urine
• Saliva
Total > 15 million aliquots
Enhancements • Web-based questionnaires for additional exposures and
outcomes (cognition, mental health, occupation..)
• Repeat of baseline assessment every few years in a
subsample of 20-25,000
• Wrist-worn accelerometers mailed to 100,000 participants to
measure physical activity
• Standard assay panel on samples from all participants
• Multimodal imaging in 100,000 - brain, cardiac and body fat
MRI; bone & joint DEXA; 3D carotid ultrasound
• Genotyping of all participants (820,000 SNPs)
• Continuous monitoring of cardiac rhythm
Neurodegenerative conditions

The Challenge
Identify early determinants
Identify early treatments to delay onset
Identify treatments to: 1. slow progression 2. relieve symptoms
Prevention Delay Slow / Relieve
The Step-change
• Dementia dedicated ‘big data’ platform
• Triangulation between multiple independent datasets
• Closer synergy between scientific specialties
• Closer partnership between academics and industry
• More targeted analytic questions
• Reducing transaction costs………
