Cognitive Function and Ageing Studies II (CFAS II)

About the cohort

Start date: 2008
Age at recruitment: >65
Sample size at recruitment: 7,524
Estimated current sample size: 7,524

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. Participants were followed up by interview throughout 2010-2011. 

CFAS II is part of the Dementias Platform UK (DPUK), a multi-million pound public-private partnership to accelerate progress in dementias research
