The Cognitive Function and Ageing Studies are large UK-based longitudinal multicentre studies looking at health and cognitive function in older people.

The study (CFAS I) started in the late 1980s with the initial aim of investigating dementia and cognitive decline in a representative sample of more than 18,000 people aged over 65 years.  To date there have been in the region of 47,000 interviews with participants in the study.The range of information collected has also allowed the study to investigate depression and physical disability in the older population and also look at healthy active life expectancy. 

New cohorts (CFAS II) based in England and Wales started in 2008, and builds on the design and infrastructure of CFAS I. It will provide data on generational and geographical differences including people in institutions. It will also provide important base-line information on older people aged 65-84 in 2007-2008 who will reach the age of greatest frailty during the 2020s when the peak in the number of people aged 85 or over is expected and at a time when major therapeutic interventions for dementia could be expected to have an effect.
