![]() 9 14 BPPV is a syndrome defined as episodes of vertigo that last less than 60 s. 14–16 Furthermore, the most common cause of vertigo without another associated neurological sign is benign paroxysmal positional vertigo (BPPV). The problem is exacerbated by fast head movements and positional changes. The main symptom observed when a vestibulopathy exists is vertigo, defined as an instability associated with a rotation sensation of oneself with respect to the environment. 9 13 In the study by Zeigelboim et al, 13 it was determined that 86% of cases of MS with vestibular problems had a peripheral origin. 10–12 In MS, although central demyelination is the most expected, vestibular peripheral aetiology is also quite common. 5 Within these canals, the most common affection is located in the altered information recorded by the posterior semicircular canal. 9 On the other hand, peripheral vestibulopathy is due to damages in the vestibular system, highlighting the semicircular canals. ![]() 7 8 Central vestibulopathy impairments can appear in neuroanatomical locations such as in the eighth cranial nerve, vestibular nuclei, oculomotor tracts, medial longitudinal fasciculus and cerebellum. ![]() 5 6 In MS, vestibular affection could have peripheral or central origin. 3 4 This symptomatology could be caused by a vestibular system affection. 1 2 Disturbances in postural control and dizziness are among the most recurrent symptoms in MS, with a direct repercussion on activities of daily living. Multiple sclerosis (MS) is a chronic autoimmune disease characterised by demyelination, gliosis and neural loss.
