Visual cortical excitability in chronic migraineurs treated with erenumab: Preliminary results of a study with sound induced flash illusions

Abstract

Surrounding environment perception can be studied using sound-induced flash illusions (SIFI): single flashes presented with two or more beeps are perceived as multiple flashes (fission illusion); the extent of such illusions is associated to changes in visual cortical excitability, known to be altered in migraineurs. We aim to evaluate SIFI changes in migraineurs after three months erenumab therapy.
