A case of migraine is presented with visual aura triggered on two separate occasions by glyceryl trinitrate (GTN). Positron emission tomography was carried out during the second triggering session. Activation in the primary visual area of the occipital cortex was demonstrated during the aura. This is the first published case of migraine aura triggered reproducibly by GTN.

Iatrogenic migraine aura following transseptal catheterization has only rarely been reported in the literature. We report the case of a 60-year-old female who presented with new onset of migraine with visual aura 1 day after transseptal cryoballoon catheter ablation for atrial fibrillation. The patient had a 5-year history of typical migraine without aura and had never experienced visual aura b...

The mechanisms underlying the initiation and propagation of the migraine aura, and the visual percept that is produces, remain uncertain. The objective of this study was to characterize and quantify a large number of visual auras recorded by a single individual over nearly two decades to gain insight into basic aura mechanisms. An individual made detailed drawings of his visual percept of migra...

BACKGROUND Cluster headache (CH) is a primary headache which has highly specific and sensitive criteria, and notpresence of an aura. It has been recently reported that CH may not presence with aura more than ever and this condition will be identified by headache specialists as a new form of CH. CASE REPORT As there is no report to our knowledge on Alice in Wonderland syndrome (AIWS) manifeste...

Smart space and smart appliances, i.e. wirelessly ad-hoc networked, mobile, autonomous special purpose computing devices, providing largely invisible support and contextaware services have started to populate the real world and our daily lives. In such a world, where literally everything is connected to everything with invisible, wireless data links, we need new styles on how humans and things ...

OBJECTIVE This study examined the association between vascular headaches and retinal microvascular disease. METHODS We investigated the cross-sectional association between headaches (migraine/other headaches with aura, migraine without aura, other headaches without aura, no headaches) and retinal microvascular signs (retinopathy, focal arteriolar narrowing, arteriovenous nicking; arteriolar a...
