The primary aim of the DEDEMAS (Determinants of Dementia After Stroke) study is to identify predictors of post stroke dementia (PSD). A particular focus will be on biological markers (neuroimaging, biochemical markers derived from blood) and on interactions between vascular and neurodegenerative mechanisms. For this purpose patients with an acute stroke and without prior dementia will be followed for 10 years. Note: Starting from 01.01.2014 this study is expanded to a multi-centric design funded by the German Center for Neurodegenerative Diseases (The DZNE - Mechanisms of Dementia After Stroke (DEMDAS) Study). This includes the following study sites: DZNE/München - Institute for Stroke and Dementia Research, Klinikum der Universität München (Coordinator); DZNE/Berlin - Neuroscience Research Center - Campus Mitte Charité; DZNE/Bonn - Klinik und Poliklinik für Neurologie, Universitätsklinikum Bonn; DZNE/Göttingen - University Medical Center Göttingen; DZNE/Magdeburg - Universitätsklinikum Magdeburg.
