Abstract:BackgroundA link has been shown between patent foramen ovale (PFO) and migraine, particularly migraine with aura.

This study aims to compare the spectrum power and functional connectivity of the alpha and beta bands of electroencephalography (EEG) across migraine patients with and without PFO.MethodsThirty-five migraine patients with PFO … Show more
