Research for everyone

PROTECT: A longitudinal study of cognition in people over 40 

PROTECT aims to understand how healthy brains age and why people develop dementia. The PROTECT study is run by the University of Exeter and Kings College London, in partnership with the NHS. 

You can join the study if you:

  • Are aged 40 years or older
  • Reside in the UK
  • Do not have a diagnosis of dementia

Once a year, you will be asked to complete a set of questionnaires about yourself, your lifestyle and your health. Each takes an hour or less to complete. You will also be asked to take a series of online tests, to measure changes in brain function.
