Unknown subjects
In a study of 64 participants, researchers found that VEP-based P100 latency was significantly associated with lower whole brain volume and gray matter volume, as well as greater T2-FLAIR lesion volumes. Specifically, longer P100 latencies correlated with these decreased volumes, suggesting a link between visual evoked potentials and brain structure outcomes in the context of multiple sclerosis.

Why it matters
These findings indicate that changes in VEP latency may reflect underlying neurodegenerative processes in MS. Understanding this relationship could enhance methods for monitoring brain health in MS patients, although further research is needed.
What this does not prove
It remains unclear whether shifts in VEP latency indicate changes in the visual pathway or are consequences of brain structural changes, limiting the ability to infer causation from these associations.

primary endpointrelationship between VEP-based P100 and MRI-based outcomes
findingsSimilarly, greater VEP-based P100 latency was directly and independently predictive of lower gray matter volume (GMV) (p=0.015) and greater T2-FLAIR LV (p=0.0036) after adjusting for RNFL and age mediating effects.
