CFAS Wales aims to interview a representative sample of 3,750 people aged 65 and over in two areas in Wales (Gwynedd and Swansea). Using established and standardised techniques it will collect data that will enable the investigation of cognitive impairment, depression, physical disability and healthy active life expectancy for the whole group and within social groups. It will provide a foundation for other collaborative studies that investigate biomarkers and other early indications of risk of cognitive decline, such as imaging. It will investigate factors that may delay the onset of dementia, specifically focussing on the role of bilingualism and social networks. As the participants reside in a bilingual area this is a key opportunity.

The AMPLE study has been set up to investigate differences and outcomes in those with Lewy body dementia with and without concurrent Alzheimer’s disease/pathology. The principle aim of AMPLE is to undertake amyloid PET imaging in Lewy Body Dementia (LBD) and Alzheimer’s disease (AD) of 80 participants over the age of 60 and investigate the distribution of amyloid burden in LBD relative to AD and controls at baseline. A further aim is to determine the relationship between amyloid levels at baseline, clinical features of the disease, other imaging changes and subsequent clinical course in follow up.

Primary analysis would divide LBD patients into high and low amyloid burden with participants then compared on clinical features with AD-like symptoms and cognitive profiles. Follow up will be completed annually through surveys and clinical examinations.

The original purpose of the Add Health study was to help understand the causes of adolescent health and health behaviour with special emphasis on the effects of multiple contexts of adolescent life.

The cohort was then followed through their transition to adulthood and research turned to understanding the determinants and consequences of developmental and health trajectories from adolescence into adulthood.

Add Health combines longitudinal survey data on respondents social, economic, psychological and physical well-being with contextual data on the family, neighbourhood, community, school, friendships, peer groups, and romantic relationships, providing unique opportunities to study how social environments and behaviours in adolescence are linked to health and achievement outcomes in young adulthood. The fourth wave of interviews expanded the collection of biological data in Add Health to understand the social, behavioural, and biological linkages in health trajectories as the Add Health cohort ages through adulthood, and the fifth wave of data collection continues this biological data expansion (2016-2018).

The PICNICS study is an observational study tracking the progression of patients with incident Parkinson’s disease over several years to better understand how the disease behaves over time, and establish the pattern of evolution of subtypes of Parkinson’s disease. Understanding differences between subtypes and what drives them will inform development of stratified therapies. The study recruited patients with Parkinson’s disease between 2008 and 2013, and is following them up every 18 months with clinical assessments, cognitive assessments and biological sampling.

The PREVENT Research Programme has established a cohort of individuals to explore differences in the brain and cognitive function in healthy people in mid-life (aged 40-59). People are grouped into high, mid and low risk based on their family history and APOE status (a well-known risk gene for Alzheimer’s disease).

650 participants are assessed on biological indicators including markers in blood, saliva, urine and spinal fluid as well as direct imaging of the brain’s structure and function. Changes in all of these markers will be monitored at 2 years to work out if risks that predict these changes. One of the main aims of the study is to identify the earliest signs of changes in the brain whilst people are still in good health.

Based at the University of Bristol, the Avon Longitudinal Study of Parents and Children (ALSPAC), also known as Children of the 90s, is a world-leading birth cohort study. Between April 1991 and December 1992 more than 14,000 pregnant women were recruited into the study and these women (some of whom had two pregnancies or multiple births during the recruitment period), the children arising from the pregnancy, and their partners have been followed up over two decades.

The cohort has been followed intensively with annual questionnaires for the mothers, fathers and the children from age 5. A 10% sample of children were seen 10 times between 4 and 61 months for clinic assessment. Annual clinic assessment of the whole cohort was conducted from the age of 7 to 13 and 15 to 17. Assessment at age 24/25 is currently planned.

Record linkage has been completed for Education, Hospital Episode Statistics, Clinical Practice Research Datalink and Death notification and cancer cases.

1 million biological samples are held including maternal blood and urine, umbilical cord blood, placentas, paternal blood and saliva and childrens blood, saliva and urine.

The study has been extended to include grandparents, siblings, and children of the children and recruitment is underway.

ALSPAC is part of CLOSER (Cohort & Longitudinal Studies Enhancement Resources) which aims to maximise the use, value and impact of the UK’s longitudinal studies.

The NSHD has informed UK health care, education and social policy for more than 70 years and is the oldest and longest running of the British birth cohort studies. Today, with study members in their seventies, the NSHD offers a unique opportunity to explore the long-term biological and social processes of ageing and how ageing is affected by factors acting across the whole of life. From an initial maternity survey of 13,687 of all births recorded in England, Scotland and Wales during one week of March, 1946, a socially stratified sample of 5,362 singleton babies born to married parents was selected for follow-up. This sample comprises the NSHD cohort and participants have been studied 24 times throughout their life.

During their childhood, the main aim of the NSHD was to investigate how the environment at home and at school affected physical and mental development and educational attainment. During adulthood, the main aim was to investigate how childhood health and development and lifetime social circumstances affected their adult health and function and how these change with age.

Now, as participants reach retirement, the research team is developing the NSHD into a life course study of ageing. Study members completed a postal questionnaire in 2014 and participated in a home visit in 2015/16, where data on health, lifestyle and life circumstances as well as obtaining repeat physical and cognitive measurements were collected. Over the past two years, a subset of 500 study members were invited to participate in a neuroimaging sub-study and over the next two years they will be recalled for a follow-up. This study will be conducted in collaboration with the Institute of Neurology, UCL.

In May 2006 a multidisciplinary team in the Institute for Ageing and Health at Newcastle University began a major groundbreaking study of the lives of those aged 85 years and older.
The study aimed to:

Assess, in great detail, the spectrum of health in the oldest old.
Examine the associations of health trajectories and outcomes with biological, clinical and social factors as the cohort ages.
Identify factors which contribute to the maintenance of health and independence.
Advance understanding of the biological nature of human ageing.

Eligible individuals will be all those who turn 85 during the year 2006 (i.e. born in 1921) and who are registered with a Newcastle or North Tyneside general practice. Participants will be visited in their current residence (own home or institution) by a research nurse at baseline, 18 months and 36 months. The assessment protocol entails a detailed multi-dimensional health assessment together with review of general practice medical records. Participants will be flagged with the NHS Central Register to provide details of the date and cause of death.

The Millennium Cohort Study (MCS) is a multi-disciplinary research project following the lives of around 19,000 children born in the UK in 2000-01. It is the most recent of Britain’s world-renowned national longitudinal birth cohort studies. The study has been tracking the Millennium children through their early childhood years and plans to follow them into adulthood. It collects information on the childrens siblings and parents. MCS’s field of enquiry covers such diverse topics as parenting; childcare; school choice; child behaviour and cognitive development; child and parental health; parents employment and education; income and poverty; housing, neighbourhood and residential mobility; and social capital and ethnicity.

The children and families have been contacted 6 times since recruitment at ages nine months, 3, 5, 7, 11 & 14 years.

MCS is part of CLOSER (Cohort & Longitudinal Studies Enhancement Resources) which aims to maximise the use, value and impact of the UK’s longitudinal studies.

The OPDC Discovery cohort is a prospective, longitudinal study that has recruited patients with early idiopathic Parkinson Disease, healthy controls and participants at risk of PD. The study also includes participants with REM Sleep Behaviour Disorder. Over 1500 subjects have been recruited to the cohort, including 1087 people with Parkinson’s, 300 healthy controls, 111 First degree PD relatives and 151 PSG-diagnosed REM sleep behaviour disorder, thought to be ‘at-risk’ of developing future Parkinson’s. All patients have a clinical assessment repeated every eighteen months so we can better understand the progression of Parkinson’s over time. Over 500 patients have been seen for a second visit which has allowed us to identify some important differences in the way Parkinson’s progresses in different people.
