visual evoked potential study in multiple sclerosis disease
purpose : to demonstrate visual evoked potential (vep) changes in multiple sclerosis (ms) disease methods : a case series study of vep changes in forty-nine patients with definite, probable and possible diagnoses of ms referred to electrophysiology ward from january 2002 to december 2005. pattern vep was done for those with good visual acuity (va), and flash vep was done for those who did not h...
متن کاملVisual evoked responses in patients with multiple sclerosis.
The visual evoked response (VER) was evaluated in a series of multiple sclerosis patients and normal subjects. The data showed significant delays in wave peak latencies among the patient evoked responses. The prolonged latencies correlated closely with visual impairment; however, even patients with a previous history of visual impairment, but with no deficits noticeable on examination at the ti...
متن کاملvisual evoked potential in diagnosis of multiple sclerosis
purpose: comparison of the results of visual evoked potential (vep) in time domain and frequency domain between multiple sclerosis (ms) suspected patients and normal indivisuals. method: eleven ms suspected patients with normal visual findings and 20 normal individuals were tested by vep. results were compared between two groups. results: the time domain results showed no significant difference...
متن کاملThe Effect of Oral Verapamil on the Visual Evoked Potentials in Definite Multiple Sclerosis Patients
Introduction: Ionic channel rearrangements through the demyelinated axons or supporting media play significant role in remission of the neurological deficit in MS patients. In this study the effects of Verapamil as a calcium channel blocker on central conduction have been investigated through the evaluation of changes in P100 latency of the visual evoked potential. Method: This randomized doubl...
متن کاملVisual and spinal evoked potentials in diagnosis of multiple sclerosis.
The measurement of cortical evoked potentials generated by pattern reversal is a sensitive technique for detecting demyelinating lesions in the anterior visual pathways.1 2 Similarly changes in the somatosensory evoked potential recorded over the cervical spine3 have been found in many patients with multiple sclerosis (MS).4 We have assessed the relative and complementary values of these two te...
