We next performed an exploratory analysis to investigate potential associations of CSF DDC and DLB-related markers (FCER2, CRH, MMP3) with different measures of DLB pathophysiology when available (i.e., UPDRS-III, post-mortem brain α-syn load, α-syn Braak stage30 and DLB stage31). The gene discussed is CRH; the disease is Lewy body dementia.
