InveCe.Ab (Invecchiamento Cerebrale ad Abbiategrasso) is a longitudinal, population-based study of disorders of brain ageing involving the assessment and long-term monitoring of the physical conditions and cognitive status. The target population comprises all Abbiategrasso residents born between 1935 and 1939, a reference sample, according to Population Register data, of around 1,700 people.

Those who agreed to participate in the Invece.Ab study were enrolled in a cross-sectional assessment and will be contacted two and four years after the initial data collection to participate in the longitudinal survey. Both the cross-sectional and longitudinal assessments include a medical evaluation, a neuropsychological test battery, several anthropometric measurements, a social and lifestyle interview, blood analyses, and the storage of a blood sample for the evaluation of putative biological markers.

The Northern Finland Birth Cohort Studies is an epidemiological and longitudinal research program which aims to promote health and well-being of the population. The prospective data collected from the Northern Finland forms a unique resource, allowing to study the emergence of diseases which can be based on genetic, biological, social or behavioural risk factors.

NFBC includes two longitudinal and prospective birth cohorts of women and offspring collected at 20-year intervals from the same provinces of Oulu and Lapland: The NFBC1966 was set with an expected date of birth in 1966, comprising of 12,068 mothers and 12,231 children (prospective data collection from maternity cards since 16th gestational week on average), and the NFBC1986 with an expected date of birth between July, 1st 1985 and June, 30th 1986, comprising 9,362 mothers and 9,479 children (prospective data collection from 10th gestational week).

Disease follow-up for all the cohorts is conducted by active follow-up every 5 years and linkage to national disease and death registries.

The Singapore Health study is a nationally representative cross-sectional survey with the aim to estimate the prevalence of:

Health conditions of hypertension, hyperlipidaemia, diabetes, overweight and obesity, hearing loss and chronic kidney disease, mental wellbeing and to allow comparison of these data with the National Health Survey 2010;
Specific health behaviours; and
Participation in health screening for chronic diseases, cervical cancer, breast cancer, colorectal cancer

2,352 Singapore citizens and permanent residents of age 18 to 79 years old participated in the survey from August 2012 to March 2013. Overall response rate was 40%. 1956 of the participants also underwent physical examination, additional surveys and provided blood and urine samples for tests and storage.

The Sydney Memory and Ageing Study (Sydney MAS) began in 2005 to examine the clinical characteristics and prevalence of mild cognitive impairment (MCI) and related syndromes, and to determine the rate of change in cognitive function over time.

Non-demented community-dwelling individuals (N=1037) aged 70-90 were recruited from two areas of Sydney, following a random approach to 8,914 individuals on the electoral roll. They underwent detailed neuropsychiatric and medical assessments and donated a blood sample for clinical chemistry, proteomics and genomics. A knowledgeable informant was also interviewed. Structural MRI scans were performed on 554 individuals, and subgroups participated in studies of falls and balance, metabolic and inflammatory markers, functional MRI and prospective memory. The cohort is to be followed up with brief telephone reviews annually, and detailed assessments biannually.

The Million Women Study is the largest study of women’s health in the world. In 1996-2001, a quarter of UK women then aged 50-64 years (1.3 million women) joined the study. The aim of the study is to provide reliable information on potentially modifiable causes of common and serious illnesses, to help improve individual and public health. Study participants have provided details about their lifestyle and health and given signed consent for follow-up. Since recruitment their health has been followed mainly through electronic linkage to routinely collected NHS records (only 1.5% loss to follow-up after 20 years) and the whole surviving cohort has been re-contacted 4 times by postal re-survey to update exposures (1999-03, 2006-7, 2009-12 & 2013-14). Subsets of women have completed additional postal and online re-surveys.

Million Women Study is part of the Dementias Platform UK (DPUK), a multi-million pound public-private partnership to accelerate progress in dementias research http://www.mrc.ac.uk/research/facilities/dementias-platform-uk

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).

ADNI began in October 2004. The overall goal is to validate biomarkers for Alzheimer’s disease clinical trials. One aim is to find, validate and standardize more sensitive and accurate methods to detect Alzheimer’s disease at earlier stages and mark its progress through biomarkers. The study gathered and analyzed thousands of brain scans, genetic profiles, and biomarkers in blood and cerebrospinal fluid that are used to measure the progress of disease or the effects of treatment. More information on ADNI-info.org. All data is publically available at USC/LONI/ADNI.

The three overarching longitudinal ADNI study goals are:

Validation of biomarkers, especially for amyloid and tau, for use in AD clinical trials.
To detect Alzheimer’s disease (AD) at the earliest stage possible and identify ways to track the disease through biomarkers.
To support advances in AD intervention, prevention and treatment through the application of new diagnostic methods to apply at the earliest stages technically possible – when intervention may be most effective.
To continually develop ADNI’s now- legendary data access policy and continuously improve and expand the unprecedented data sharing model.

Aims & objective

To find out the known as well as some new factors which increase the risk of occurrence of stroke (half body paralysis, Lakwa) and of memory problem and other brain related problems.
To identify a group of apparently healthy people (50 years and above), carry out their health check up and follow them up over several years to detect any health problems (like heart attack, lakwa, memory problems) with increasing age.
To investigate the prevalence and incidence of and risk factors for stroke and cognitive decline in the elderly.

Updates about the health of the participants will be obtained from telephone follow-ups every six months and physical check-ups every three years. The study is expected to last for at least 10 years.

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.

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.
