Pattern reversal visual evoked potentials in migraine subjects without aura.
Twenty seven patients with migraine without aura were investigated. The age was between 12 and 54 years; 5 were men and 22 women. The diagnosis of migraine was made according to the classification proposed by the International Headache Society. The method of visual evoked potential was performed with pattern reversal (VEP-PR), with monocular stimulation. The stimulation was performed with patte...
متن کاملMigraine, cortical excitability and evoked potentials: a clinico-pharmacological perspective.
Coppola et al., (2005) studied somatosensory evoked highfrequency oscillations (HFO) in migraine patients between attacks and advances the hypothesis that the habituation deficit in migraine patients is owing to a reduced pre-activation level of sensory cortices. While further proposing that a reduced interictal excitation (‘pre-activation’) level might be the pathophysiological basis of migrai...
متن کاملThe pattern--reversal visual evoked potentials in children with migraine with aura and without aura.
PURPOSE Studies of the visual evoked potentials (VEP) in migraine have yielded contradictory results. Several investigators suggested that VEP may be helpful test in diagnosis of a child with headache. The aim of our study was to compare interictal pattern-reversal visual evoked potentials (PR-VEP) in children and adolescents with migraine and tension-type headaches and to evaluate VEP paramete...
متن کاملVisual evoked potentials during long periods of pattern-reversal stimulation in migraine.
We have previously shown that during repetitive pattern-reversal stimulation, lasting 2 min, the amplitude of the visual evoked potential (PR-VEP) increases in migraineurs when tested interictally whereas it decreases in healthy control subjects. According to Sappey-Marinier et al. (J Cereb Blood Flow Metab 1992; 12: 584-92) habituation of the PR-VEP in normal subjects is maxima after 12 min, a...
متن کاملEffects of repetitive transcranial magnetic stimulation on visual evoked potentials in migraine.
Between attacks, migraine patients are characterized by potentiation instead of habituation of stimulation-evoked cortical responses. It is debated whether this is due to increased or decreased cortical excitability. We have studied the changes in visual cortex excitability by recording pattern-reversal visual evoked potentials (PR-VEP) after low- and high-frequency repetitive transcranial magn...
