Abstract

Objectives: Multiple sclerosis (MS), is an inflammatory disease of the central nervous system in which the formation is very characteristic of demyelinated lesions in the brain and spinal cord. Conducting a diagnosis of Multiple Sclerosis supported by Somatosensory evoked potential (SSEP) is essential, not only for diagnosis, but also for the pathophysiological treatment. Methods: Crosssectional descriptive study of 30 patients at the neurological department of Nghe An hospital from January 2021 to Octorber 2021. Results: the average age of patients with Multiple Sclerosis was 32,73 ± 2,27, commonly from 20 to 50years old. There were 7 males (23.3%) and 23 females (76.7%) enrolled in this study. The incidence of the disease is higher in women than in men, female/male ratio is 3.3:1. The patients with normal N9 waves were common (93.33%), while abnormal N13 waves accounted for 80% and abnormal N20 accounted for 86.7%. Among patients with abnormal N13 waves, the number of patients with increased latent time was 37.5%, or the patients without N13 waves was commonly 62.5%. With N20 waves, 8 patients had increased latent time, 18 patients lost N20 waves (69.2%). The patients with symptoms such as limb numbness and disorder of anal sphincter had abnormal N13 and N20 waves accounting for high percentages (73.3 – 85.7%), while normal N9 waves accounted for the majority. Conclusion: The patients with symptoms such as limb numbness and disorder of anal sphincter had abnormal waves higher than normal waves.
