NEFL and Lewy body dementia: We found that the plasma Aβ42/40 ratio was higher in patients with DLB compared with AD and not significantly different from HC, while plasma GFAP and NfL were higher in patients with DLB and AD compared with HC, but not significantly different between DLB and AD, and P-tau181 and P-tau231 were significantly higher in DLB compared with HC and significantly lower in DLB and HC compared with AD.
