Evidence of an increased neuronal activation-to-resting glucose uptake ratio in the visual cortex of migraine patients. A study comparing18FDG-PET and visual evoked potentials
Background: Migraine attacks might be triggered by a disruption of cerebral homeostasis. During the interictal period migraine patients are characterized by abnormal sensory information processing, but this functional abnormality may not be sufficient to disrupt the physiological equilibrium of the cortex unless it is accompanied by additional pathological mechanisms, like a reduction in energetic reserves.
