Longitudinal Analysis of P100 Wave Amplitude and Latency in Multiple Sclerosis: A 19-Year Retrospective VEP Study [PDF]

Diagnostics
Background: The diagnosis of multiple sclerosis (MS) relies on identifying neurological signs and symptoms, supported by evidence of central nervous system (CNS) dissemination of lesions across time and space.

The Correlation of PANSS Scores and P100 Latency in Patients with Schizophrenia and Migrene Hedache Using Visual Evoked Potentials (VEPS) According to Gender and Age. [PDF]

Acta Inform Med, 2022
Background: The VEPs provide an objective measure of brain function, analyzing integrity of visual processing. With patients affected with schizophrenia, the changes with the implementation of VEP are evident, such as symmetrical deceleration of the impulse and the continuance of latency, which points to a degenerative illness, suggesting the presence ...

P100 Wave Latency and Amplitude in Visual Evoked Potential Records in Different Visual Quadrants of Normal Individuals

Journal of Ophthalmic & Vision Research, 2023
Purpose: Assessment of the pattern visual evoked potential (PVEP) responses in different areas of visual fields in individuals with normal vision. Methods: This study was conducted on 80 eyes of normal subjects aged 18–35 years.

From demyelination to neurodegeneration in multiple sclerosis: reassessing the role of visual evoked potential P100-N145 amplitudes: a missing piece of the puzzle? [PDF]

Frontiers in Neurology
BackgroundMultiple sclerosis (MS) is a chronic demyelinating disease with a heterogeneous clinical course, making long-term disability prediction challenging.

Delayed P100-Like Latencies in Multiple Sclerosis: A Preliminary Investigation Using Visual Evoked Spread Spectrum Analysis. [PDF]

PLoS ONE, 2016
Conduction along the optic nerve is often slowed in multiple sclerosis (MS). This is typically assessed by measuring the latency of the P100 component of the Visual Evoked Potential (VEP) using electroencephalography.

Normative values of visual evoked potential in adults

Indian Journal of Ophthalmology, 2021
Purpose: Visual evoked potentials (VEP) are used to determine the function of visual pathway from the optic nerve to visual cortex. Various factors may affect VEP response, viz., technical and environmental.

Crotonylation sensitizes IAPi-induced disruption of latent HIV by enhancing p100 cleavage into p52

iScience, 2022
Summary: The eradication of HIV infection is difficult to achieve because of stable viral reservoirs. Here, we show that crotonylation enhances AZD5582-induced noncanonical NF-κB (ncNF-κB) signaling, further augmenting HIV latency reversal in Jurkat and ...

Comparative study between visual evoked potential and visual acuity, field of vision, and fundus examination as screening tool for early diagnosis of hydroxychloroquine and chloroquine retinal toxicity in rheumatic patients

Journal of Medicine in Scientific Research, 2020
Objectives The current study was conducted to compare between the conventional eye examination methods named as visual acuity, fundus examination, and field of vision evaluation in one hand and electrophysiologic methods of eye examination as visual ...
