Welcome to the website of the EDAR study. The EDAR study is a European collaborative study, which aims to develop and validate new biomarkers for Alzheimer’s disease.

Central in the project is the development of an assay for the measurement of beta amyloid oligomers in cerebrospinal fluid and plasma. Beta amyloid oligomers have been recognized as a key pathogen in AD only recently. Due to their low concentration, they cannot be measured with regular techniques. In the present study, ultra-sensitive assays will be developed in order to measure oligomers in vivo.

In order to validate the assay for beta amyloid oligomers, cerebrospinal fluid and plasma will be repeatedly collected in subjects with Alzheimer’s disease, other types of dementia, Mild Cognitive Impairment, and control subjects.
