Occipital activation in glyceryl trinitrate induced migraine with visual aura
Abstract
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.
