The EADC-PET project (EAPP, The European Alzheimer’s Disease Consortium PET project) is a spontaneous multicentric study (ProtocolDraftSep2008; ProtocolDraftFeb2009) involving at the moment five Centres in four Countries (CENTRES), belonging to the EADC consortium. It was launched during the EADC meeting in Amsterdam, during fall 2007, by Flavio Nobili (Genoa) who is the Principal Investigator.

The project aims at sharing FDG-PET, MRI, neuropsychological, genetic, EEG and clinical information of patients with amnestic Mild Cognitive Impairment (aMCI) and matched healthy controls. Information is uploaded in a safe FTP facility on the server of University of Genoa. Username and password have been provided to all participants. Use of data is regulated by a 'Confidentiality Disclosure Agreement’ that can be downloaded from this web site (Confidential_Disclosure_Agreement). The Centres propose original studies by sending a formal proposal to all participants who can agree or disagree, or propose modifications/suggestions to the original proposal.

The objective is to follow-up aMCI patients with clinical and neuropsychological examinations to pick up conversion to Alzheimer’s dementia or to other forms of dementia. FDG-PET can be analyzed by means of several post-processing strategies to highlight glucose metabolic information and to identify the characteristics of what is today called 'prodromal’ AD.

The EVA study was a 9-year longitudinal study with 6 waves of follow-ups. During the two-year period 1991-1993 (EVA0), 1389 men and women born between 1922 and 1932 were recruited.

The aim is to investigate vascular ageing, decline in brain and cognitive function and associated factors with a longitudinal follow-up study. The secondary objective is to determine to role of biological factors linked with oxidative stress and brain ageing.
Inclusion criteria Subjects from both genders born between 1922 and 1932 (59 to 71 years old at enrolment), included in electoral registers in Nantes, can speak French and living in Nantes.

The aim of GS: SFHS is to establish a large, family-based intensively-phenotyped cohort recruited from the general population across Scotland, as a resource for studying the genetics of health areas of current and projected public health importance. It aims to identify genetic variants accounting for variation in levels of quantitative traits underlying the major common complex diseases (such as cardiovascular disease, cognitive decline, mental illness) in Scotland.

Baseline data was collected at a single clinic visit. Longitudinal data is available by linkage to NHS medical records. Some participants are being invited to new clinic visits in 2015-17. This profile also includes scanning information from the Stratifying Resilience and Depression Longitudinally (STRADL) study to which approximately 1500 GS participants are being invited for scanning.

The Lc65+ project is a longitudinal population-based study focusing on the development of frailty after the age of 65. The main methods in the Lc65+ study are:

ﾕ long term observation of subjects, beginning at 65 to 70 years, an age when frailty is still unusual, in order to study its initiation and development;
ﾕ prospective data collection on a large range of health dimensions, including psycho-social characteristics, in order to investigate the temporal sequence linking frailty, its risk factors, modulators, and outcomes:
ﾕ a population approach considering frailty as a central parameter of health in ageing populations that is useful not only for surveillance, but also for the evaluation of preventive interventions.

Follow-up is based on a yearly questionnaire sent by mail to the participant’s home. In addition, subjects are invited to the study center every three years for an interview and examination similar to those performed at baseline. The follow-up is unlimited in time and is not interrupted in the case of nursing home admission.

The Older Australian Twins Study is a longitudinal, multi-centre study that investigates healthy brain ageing in older twins (65+ years). OATS commenced in New South Wales in January 2007, in Queensland in December 2007, and in Victoria in February 2008. Since the OATS study started we have followed our twin volunteers up every two years to check on their psychological and physical health. Participants undergo rigorous medical and cognitive function tests, with many participants’ also providing bloods samples and having a magnetic resonance imaging (MRI) scan of their brain. In 2015 we finished our 4-year follow ups. OATS assessed 623 participants at baseline, 450 at the 2-year follow up, and 389 completed their 4-year follow-up.

The Puerto Rican Elderly: Health Conditions (PREHCO) study investigates issues affecting the elderly (individuals over 60 years of age) population in Puerto Rico: health status, housing arrangements, functional status, transfers, labor history, migration, income, childhood characteristics, health insurance, use of health services, marital history, mistreat, sexuality, etc. It is an island-wide, longitudinal sample survey of target individuals and their spouses with two waves of data collection: 2002-2003 and 2006-2007.

In the first phase of the PREHCO project, 4,291 elderly persons 60 years or older and 1,442 spouses were interviewed (1,042 of the latter being 60 years or older). A second wave of the project (2006-2007) converted PREHCO in a longitudinal study. In the second wave, those same participants were asked to do a follow-up survey, in which 3,891 target interviews and 1,260 spouse interviews were completed. The deceased and institutionalized participants were also interviewed using a proxy.

The rpAD study is a longitudinal study, which recruits patients from the entire federal territory. In addition, patients from the Clinical Dementia Centre are recruited at the Neurological and Psychiatric Clinic of the University Medical Center of G’ttingen, with these usually classical clinical forms being internal controls. The aim of the study is to characterize the biological factors and parameters that define the disease progression in AD.

After the patient is informed and consent is given, the inclusion examination is carried out. It includes a detailed history and anamnesis as well as a physical examination, which includes an in-depth examination of the neurological status. A neuropsychological test for cognitive testing is performed using the CERAD-plus test battery. Furthermore, the GDS score is obtained, which allows an assessment of the severity of the cognitive deficits by means of a 7-stage classification. The ADL score is used to assess the activities of daily life (Lawton and Brody 1969).

Six months after the initial examination, a telephone follow-up is carried out. Further investigations are carried out on an annual basis and correspond to the initial examination.

The Rhineland Study is a prospective cohort study, which began in March 2016. It will include up to 30,000 participants from Bonn and asses their physical and mental health over their lifespan. The study is scheduled to run for decades and participants will be re-examined every 3-4 years.

As neurodegenerative diseases and their pathologies develop over a long time before first symptoms start to show, the Rhineland Study will include men and women aged 30 years and above regardless of their health status.
The main aims of the study are:

1. To investigate modifiable and non-modifiable causes of neurodegenerative and neuropsychiatric diseases
2. To find biomarkers/(multimodal) biomarker profiles to identify individuals at risk for neurodegenerative or neuropsychiatric disease, who might benefit from preventive interventions
3. To investigate (patho)physiology over the adult life course, with specific emphasis on brain-related outcomes.

For 30 years (since 1987) tracks the health of a group of randomly selected adult Dutch inhabitants of Doetinchem from originally between 20-60 years. This provides a wealth of information of four generations: 20-29, 30-39, 40-49 and 50-60 year olds. The name of this study is the Doetinchem Cohort Study. Every five years the health and habits of the participants are examined at the local health department.

The purpose of the Doetinchem Cohort Study is to give insight into trends in lifestyle and health. So there will be more and more knowledge about why some people age without many problems, while others have health problems at an early age. The study collects data on:

  • Lifestyle habits: exercise, diet, smoking, alcohol consumption;
  • Biological factors: blood pressure, cholesterol, (over) weight;
  • Several specific diseases: cardiovascular disease, asthma, COPD , diabetes, cancer, migraine, musculoskeletal;
  • Quality of life: cognitive functioning, social participation, psychosocial aspects of health.
