Of the participants with DLB, participants with BG-PVS were more likely than those without BG-PVS to have greater cognitive impairment, a history of fall, higher Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (UPDRS) scores, higher PWV, and higher concentrations of plasma NfL; however, age was nearly equal between the two groups (Table S4). The gene discussed is NEFL; the disease is movement disorder.
