The Gipuzkoa Alzheimer Project (PGA) is a longitudinal study on pre-clinical Alzheimer’s disease. This study aims to investigate the prevalence, clinical, cognitive and neuroimaging features and potential risk factors related to cardiovascular health and lifestyles for pre-clinical AD in asymptomatic (or very mildly symtopmatic, e.g. SCD) subjects from the community.

Follow-up Scheduled every 3 years for a minimum of 12 years. The first 3-year follow-up was completed in June 2015. The loss of subjects in the follow up was 9 %. 80% of people who donated cerebrospinal fluid at the baseline visit did the same in this follow-up visit. Second follow-up visit (6 yrs) to be started in April 2017.

The Cambridge City over-75s Cohort Study (CC75C) is a long-term follow-up study of a representative population-based sample of older people which started in 1985 from a survey of over 2,600 men and women aged 75 and above. Through a series of interviews and assessments spanning almost three decades they have contributed to one of the largest and longest-running longitudinal observational studies of ageing into older old age.
The initial study targeted all men and women aged 75 or older who were registered within a selection of geographically and socially representative general practices in Cambridge, and achieved a 95% response rate in six of the seven practices. From this original survey of 2610 people, 2166 individuals form the baseline sample for the longitudinal cohort. This group has been followed up through ten surveys, with sub-groups assessed more often. Similarly high response rates amongst participants still alive in their late 80s or 90s, and even amongst centenarians, have built an extensive resource of quantitative and qualitative data contributed by a representative sample of very old people and their relatives.
The focus in later years shifted to quality of life issues of ‘older old’ people near the end of life for which we have been interviewing relatives or carers of surviving members of the cohort all aged 95 or more, as well as these study participants themselves.

The Boyd Orr cohort is an historical cohort study carried out by the University of Bristol School of Social Medicine to investigate the long term impact of children’s diet, growth, living conditions and health on adult cardiovascular disease. It is based upon based on the 65 year follow-up of the Carnegie Survey of Diet and Health (1937-9).

It is based on the long term follow-up of 4,999 children who were surveyed in the Carnegie United Kingdom Trust’s study of Family Diet and Health in Pre-War Britain (1937-1939). With funding from the British Heart Foundation, the cohort was established in 1988 by Professors George Davey Smith and Stephen Frankel who retrieved the original research records of the pre-war survey from the Rowett Research Institute.
