The CFAS I study 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 allowed the study to investigate depression and physical disability in the older population and also look at healthy active life expectancy. Following baseline interviews, subsets of the cohort have been contacted for 1, 2, 6 and 8 year follow up and the whole sample was contacted for a 10 year follow up. There have also been 500 donations of participants' brains after death.
