We have studied habituation of the pattern-reversal visual evoked potential (VEP) in healthy volunteers (n = 16) and in patients suffering from migraine without (n = 27) or with aura (n = 9). Five blocks of 50 responses at a stimulation rate of 3.1 Hz were sequentially averaged and analyzed separately for latencies, peak-to-peak amplitudes of N1-P1 and(More)
Cortical information processing in migraine patients is impaired between attacks, showing deficient habituation of pattern-reversal visual evoked potentials (VEP), and strong intensity dependence of auditory cortical evoked potentials (IDAP). This could be a genetic trait as certain genetic patterns are known for evoked potentials in healthy subjects. We(More)
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(More)
Migraine patients show impaired cortical information processing between attacks with deficient habituation of pattern-reversal visual evoked potentials (VEP), and strong intensity dependence of auditory cortical evoked potentials (IDAP).

OBJECTIVE To investigate whether colored glasses influence the habituation of visual evoked potentials. BACKGROUND We have previously shown that during pattern-reversal stimulations lasting 2 minutes the amplitude of the visual evoked potential increases in migraine with and without aura between attacks, whereas it decreases in healthy volunteers.

BACKGROUND Country-specific prevalence data on migraine and comorbidities are vital to assess the public health burden of migraine and the corresponding resources required for proper management. Considering the absence of reliable statistics, this study aimed to estimate the one-year prevalence of migraine in Wallonia (Belgium) in relation to(More)
The endoscopic endonasal transsphenoidal approach is a minimally invasive surgical technique for the removal of sellar and parasellar lesions. It allows panoramic vision of the surgical target and surrounding structures, with minimal trauma and a low complication rate. The procedure has been gaining in popularity in recent years. There are now surgical(More)
