Functional and effective connectivity alterations relate to cognitive performance in aquaporin-4 antibody-positive neuromyelitis optica spectrum disorder
Abstract The neural mechanisms underlying cognitive dysfunction in aquaporin-4 antibody-positive neuromyelitis optica spectrum disorder (AQP4 + NMOSD) remain unclear. Functional connectivity (FC) studies have revealed network-level alterations, but little is known about the effective interactions that support compensat...
