Abstract
We investigated changes of after-image duration in migraineurs and healthy controls (HCs) and throughout the migraine cycle to depict changes in the excitatory/inhibitory equilibrium within the visual cortex. Forty-seven episodic (EMs) and 39 chronic migraineurs (CMs; interictal) were compared to 34 HCs for visual after-image duration. Additionally, seven EMs were investigated every consecutive day over 20 to 32 days using the identical paradigm throughout the migraine cycle. Interictally, the after-image duration was shorter compared to HCs, but significantly longer in the ictal compared to interictal phase. These data suggest an altered excitatory/inhibitory equilibrium in migraineurs, which oscillates over the migraine cycle. ANN NEUROL 2019;85:280–283.
