- W1979545822 abstract "Objective: To examine the association of visual evoked potential (VEP) latency and high-contrast visual acuity (VA) with cognitive function in MS patients using a standardized computerized battery. Background Cognition and vision are now recognized as important domains for clinical trials assessment in MS. The correlation of VEP conduction delay and VA with cognitive impairment has not been described. Design/Methods: Participants received a VEP evaluation as well as a Snellen vision test and completed a standardized, validated MindStreams battery designed to detect mild impairment (NeuroTrax Corp., NY) in their primary language. VEP latency categories were: normal =113 and =130 and =150 and 170 msec. Results: Among MS patients (n=435, 870 eyes), Accounting for age, disease duration, and within-patient, inter-eye correlations, abnormal VEP latency was associated with poorer overall battery performance (Global Cognitive Score, p Conclusions: Abnormal VEP latency and high-contrast VA in patients with MS may be associated with reduced cognitive function, particularly in domains related to executive function. Longer VEP latency may be particularly related to poorer visual spatial processing. Further studies will examine the role of afferent visual dysfunction and retinal axonal and neuronal loss in the relation of VEP latency to cognitive impairment and work disability in MS cohorts.
