Abnormalitites of Visual Evoked Potential in Migraine Patients
Background: Visual evoked potential (VEP) is regarded as a useful, reliable and non-invasive technique for the diagnosis of lesions in the optic pathway. This technique was used to investigate visual function in migraine. Materials and Methods: 53 migraine patients (27 migraine cases with aura and 26 common migraine cases) and 55 controls were prospectively enrolled in this study. Visual ev...
متن کاملMachine learning based Visual Evoked Potential (VEP) Signals Recognition
Introduction: Visual evoked potentials contain certain diagnostic information which have proved to be of importance in the visual systems functional integrity. Due to substantial decrease of amplitude in extra macular stimulation in commonly used pattern VEPs, differentiating normal and abnormal signals can prove to be quite an obstacle. Due to developments of use of machine l...
متن کاملMotor evoked potential polyphasia
Objective: We compared the motor evoked potential (MEP) phases using transcranial magnetic stimulation in patients with idiopathic generalized epilepsy (IGE), their relatives, and healthy controls, hypothesizing that patients and their unaffected relatives may share a subtle pathophysiologic abnormality. Methods: In a cross-sectional study, we investigated 23 patients with IGE, 34 first-degree ...

~urol Neurosurg 1ge: clinical and complications, but the monitoring methods must be simple to perform, sensitive, and reliable. Median nerve somatosensory evoked potential (SEP) monitoring fulfills these criteria. Between 1985 nd 1990, we performed 994 h S. Successful operations of the carotid artery with SEP monitoring. In 92% of the cases, we were able t obtain viable SEP tracings. 3.. Case r...
متن کاملChapter 7 : Evoked potential audiometry
When conventional behavioural audiometry is difficult or impossible, or when its results are inaccurate or suspect, there is a need for more objective hearing tests. Candidates for such tests include young infants, uncooperative, hyperactive, or neurologically impaired children, and those suspected of non-organic hearing loss. The usual goal is to approximate pure tone thresholds, using some me...
