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.

Physiological determinants of cortical P100 responses in pattern visual evoked potentials: a scoping review [PDF]

Frontiers in Neuroscience
BackgroundPattern visual evoked potentials (pattern VEP) are widely used for functional assessment of the visual pathways. The P100 component represents the principal clinical parameter owing to its relative interindividual stability and diagnostic value.

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.

Prospective Matched Case-Control Study of Over-Early P100 Wave Latency in Migraine with Aura

Biomedicines, 2023
A sizable portion of the world’s population suffers from migraines with aura. The purpose of this research is to describe the findings of a case-control study that was carried out to gain a better understanding of how migraine with aura manifests. The research looked at the P100 delay of the visual-evoked potential in both eyes of 92 healthy people and

Specificity and sensitivity of visual evoked potentials P100 latency to different events exercise

Health, 2009
Visual evoked potentials (VEPs) are a series of signals about visual occipital cortex in response to visual stimuli and can be used as one of ob-jective non-invasive neuro-physiological pa-rameters to reflect the visual organs and central visual pathway’s functional integrity.

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.
