Vestibular evoked myogenic potentials in patients with rheumatoid arthritis

  Background: Rheumatoid arthritis (RA) is an autoimmune systemic disease. Most common autoimmune diseases are multisystem disorders that may also present with otological manifestations, and autoimmune inner ear disease accompanied by vestibular dysfunction. This study aimed to compare the vestibular function between RA patients and normal subjects using cervical vestibular evoked myogenic...

[Albinism: diagnosis by visual evoked potentials].

BACKGROUND In albinism the majority of the nerve fibers of the optic nerve originating from an eye are innervating the contralateral hemisphere. As a result of the predominantly monocular innervation of the left and right hemispheres, the unilateral activation of the visual cortex (lateralization) can be detected with visual evoked potentials (VEP). PATIENTS AND METHODS The VEPs were elicited...

Visual 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...

Visual evoked potentials in the diagnosis of multiple sclerosis.

A three-year collaborative study was done on 96 patients presenting with signs of neurological dysfunction suggestive of multiple sclerosis. All were tested using Visual Evoked Potentials, with the final diagnosis not known to the tester. Patients with bilateral Visual Evoked Potential P1 wave conduction delays were more likely to have a subsequent diagnosis of MS, than those with unilateral de...
