Dementia, Lewy Body

The study aims to systematically document the course of REM sleep behavior disorder (RBD) and investigate possible clinical and imaging biomarkers for disease progression and conversion risk to Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA). The study will use artificial intelligence to analyze imaging and develop a reliable method to predict and stratify patients approaching conversion to overt a-synucleinopathy. Participants will be clinically evaluated and 2 imaging procedures will be done.

The goal of the study is to develop predictive algorithms and digital biomarkers to capture disease fluctuations in (prodromal) dementia with lewybodies (DLB) patients and to improve treatment, diagnosis and prognosis of the study drug Ambroxol, used in the ANeED study. This project is an additional study to the ANeED study, registered at ClinicalTrials.gov under NCT04588285.
