The goal of this observational study is to improve the detection of dementia with Lewy bodies (DLB) and its prodromal phases, as well as advancing our current understanding of biological mechanisms and therapeutic options. The data is acquired at cognitive clinics in Stockholm (Sweden) and combined with national and international data to increase statistical power, representativeness and replication of results. Participants undergo collection of clinical assessments, neuroimaging and fluid biomarkers.
