Multiple sclerosis (MS) is a complex disease of the central nervous system (CNS), characterized by inflammation, demyelination, neuro-axonal loss, and gliosis. Inflammatory demyelinating lesions are a hallmark of the disease. Spontaneous remyelination, however, is often incomplete and strategies that promote remyelination are needed. As a result, accurate and sensitive measures of remyelination are necessary. The visual pathway provides a unique opportunity for assessment of myelin damage and repair in the MS-affected brain since it is highly susceptible to damage in MS and is a very frequent site of MS lesions. The visually evoked potential (VEP), an event-related potential generated by the striate cortex in response to visual stimulation, is uniquely placed to serve as a biomarker of the myelination along the visual pathway. The multifocal VEP (mfVEP) represents a most recent addition to the array of VEP stimulations. This article provides a current view on the role of mfVEP as a biomarker of demyelination, spontaneous remyelination, and myelin repair in MS.
多发性硬化症(MS)是一种中枢神经系统(CNS)的复杂疾病,其特征为炎症、脱髓鞘、神经轴突损失和胶质增生。炎性脱髓鞘病变是该疾病的一个标志。然而,自发的髓鞘再生往往不完全,因此需要促进髓鞘再生的策略。结果,准确且敏感的髓鞘再生测量方法是必要的。视觉通路为评估MS影响的大脑中的髓鞘损伤和修复提供了独特的机会,因为它在MS中极易受损,且是MS病变的常见部位。视觉诱发电位(VEP)是由纹状皮质对视觉刺激产生的一种事件相关电位,非常适合作为视觉通路髓鞘化的生物标志物。多焦点VEP(mfVEP)是VEP刺激阵列中的最新成员。本文提供了关于mfVEP作为MS中脱髓鞘、自发髓鞘再生和髓鞘修复生物标志物作用的当前观点。
