Headache caused by paroxysmal vestibular symptoms Known as vestibular migraine (VM), its pathophysiology and related mechanisms are less understood at this stage. The purpose of this study was to apply Simultaneous Multi-Slice Resting State functional Magnetic Resonance Imaging (SMS-Rs-fMRI) to explore the gray matter volume (GMV), brain function, and brain default in patients with VM..Compared with the control group, patients with VM had lower GMV in multiple brain areas, higher ALFF values in multiple brain areas, and changes in the brain default network function connection in the resting state.
