Abstract
Background: Migraine is a common neurovascular disorder. Visual evoked potential (VEP) changes, between migraineurs and normal subjects, were often conflicting.
Objective: Compare VEP (P100) in patients with migraine with and without aura to normal subjects, and the effect of prophylactic treatment.
Methods: Visual evoked potential was recorded in 32 patients with migraine and 15 healthy control subjects.
Results: P100 amplitude was significantly higher and its latency was significantly longer in patients with migraine compared to control subjects, this difference disappeared in patients with regular prophylactic treatment.
Conclusion: Cortical excitability changes may be related to the pathophysiology of migraine and the efficacy of prophylactic treatment.
