dc.description.abstractObjectives, This study aimed to examine the vestibulo-collic reflex (VCR) and linear vestibulo-ocular reflex (lVOR) and their correlation with brain lesions in pediatric-onset multiple sclerosis (POMS). Methods, The study group consisted of 17 patients (34 ears) with POMS (mean age 18.73 ± 2.02, mean age at disease onset 14.64 ± 1.36 years), and the control group included 11 age-matched healthy subjects (22 ears). Ocular and cervical Vestibular Evoked Myogenic Potentials (oVEMP and cVEMP) were performed to assess IVOR and VCR pathways. Magnetic Resonance Imaging was evaluated in the study group. Results, In the POMS group, 47.05 % of oVEMPs and 17.64 % of the cVEMPs were abnormal, while all VEMPs were normal in the control group. The oVEMP amplitude was associated with infratentorial lesion volume (r = −0.459, p = 0.01) and total lesion volume of the brainstem and cerebellum (r = −0.450, p = 0.01). The cVEMP asymmetry ratio was correlated with the deep white matter lesion volume (r = 0.683, p < 0.001). The MVEMP scores were found to correlate only with lesion volumes in the cerebellum (r = 0.488, p = 0.04) and infratentorial region (r = 0.573, p = 0.01). Conclusions, Ocular and cervical VEMP abnormalities confirm that lVOR and VCR pathways may be affected in early POMS. Significance, Routine use of the VEMP test, especially the oVEMP test is recommended as a useful tool in the follow-up of POMS patients.en_US
