BACKGROUND AND PURPOSE Functional neuroimaging studies have shown hyperresponsiveness of cortical areas to visual stimuli in migraine patients with aura outside of attacks. This may be a key feature in the initiation of aura episodes and possibly also migraine headache attacks. It is unknown if cortical dysfunction is present at rest, i.e. in the absence of(More)
OBJECTIVE It is well-known that migraine attacks can be precipitated by various stimuli. More than 50% of patients with migraine with aura (MA) know of at least one stimulus that always or often triggers their MA attacks. The objective of this study was to expose patients with MA to their self-reported trigger factors in order to assess the causal relation(More)
AIM To explore a possible differential effect of sumatriptan on extracerebral versus cerebral arteries, we examined the superficial temporal (STA), middle meningeal (MMA), extracranial internal carotid (ICAextra), intracranial internal carotid (ICAintra), middle cerebral (MCA) and basilar arteries (BA). METHODS The arterial circumferences were recorded(More)
