Impact of Hyperventilation and Sleep Deprivation upon Visual Evoked Potentials in Patients with Epilepsy

摘要

Objectives: The diagnosis of epilepsy can cause many problems, especially when the routine electrophysiological tests are inconclusive. The aim of the present study was to assess the visual evoked potential (VEP) in patients with epilepsy using various kinds of stimulation and activation tests. The VEP parameters were also presented with reference to the type of seizure and abnormalities in electroencephalogram (EEG), including the response to the activation tests.
