Imaging Studies in Corticobasal Syndrome

The primary goal of this study is to investigate inflammation and white matter damage in corticobasal syndrome and determine whether these processes are related to each other. The investigator's will address our goal by using neuroimaging and blood plasma biomarkers, as well as molecular pathology.
