Abstract

Migraine arises from a primary brain dysfunction that leads to episodic activation and sensitization of the trigeminovascular pain pathway. About one third of patients with migraine experiences transient neurological symptoms during attacks, so-called “aura”, among which the most common is visual aura [1]. In our previous fMRI study, we had observed a significantly increased resting-state visual network (RS-VN) functional connectivity in patients with migraine with aura (MwA) compared to patients with migraine without aura (MwoA) during the interictal period [2]. Nevertheless, both whole-brain and visual pathways microstructural white matter (WM) abnormalities in patients with MwA and MwoA is still under debate.
