Brief summary

Dementia is a clinical syndrome that is the result of distinct underlying pathologies including Alzheimer's disease (AD). Despite more than two decades of research on prevention and treatment of dementia and aging-related cognitive decline, highly effective preventive and therapeutic strategies remain elusive. Many features of dementia render it especially challenging. Indeed development of disease occurs insidiously over the course of years or decade. In addition, the causes of dementia and determinants of its severity are likely multi-factorial. To overcome these challenges and better understand the causes and course of AD and related disorders, long term follow-up studies of persons at high risk of dementia are required including multidimensional and harmonized assessment of risk factors, phenotypes (cognition, neuropsychiatric symptoms, physical health, self rated health) and endophenotypes (blood markers, genetic markers, neuroimaging markers). This project proposes an extension of the follow-up of Memento participants over 5 to 10 years with of focus on cognitive outcomes and comorbidities.
