Evoked potentials in multiple sclerosis.

Area of Science:

• Neuroscience
• Clinical Neurology
• Diagnostic Imaging

Background:

• Historically, evoked potentials (EPs) were crucial for diagnosing multiple sclerosis (MS).
• EPs, including visual evoked potentials (VEPs), somatosensory evoked potentials (SEPs), and brainstem auditory evoked responses (BAERs), identified central nervous system (CNS) lesions.
• These electrophysiological tests supplemented physical examinations to confirm the "multiple" sites of disease characteristic of MS.

Purpose of the Study:

• To provide an overview of the continued utility of EPs in managing MS.
• To highlight how CNS physiology, assessed via EPs, remains valuable despite the prevalence of MRI.

Main Methods:

• Review of the historical and current applications of EPs in MS diagnosis and management.
• Discussion of how EPs measure CNS physiological function.

Main Results:

• EPs were foundational in diagnosing MS before MRI.
• EPs can still offer valuable insights into CNS function in MS patients.
• The electrophysiological data from EPs complements findings from MRI and clinical assessments.

Conclusions:

• Evoked potentials retain clinical relevance in the management of multiple sclerosis.
• EPs provide a valuable measure of CNS physiology that complements modern neuroimaging techniques like MRI.
• Understanding EPs' role enhances comprehensive MS patient care.
