SUMMARY:

Introduction: Diseases of the central nervous system (CNS) are those that affect the brain and spinal cord. The damage associated with otoneurological symptoms is already well documented in the scientific literature. This happens as a result of lesions in the central vestibular pathways, formed by the cerebellum, brainstem, thalamus, spinal cord and cerebral cortex. Objective: (1) To investigate the applicability of the Video Head Impulse Test (vHIT) in the assessment of the vestibulo-ocular reflex (RVO) in individuals with CNS diseases. (2) To characterize the neurological and vestibular findings of clinical cases diagnosed with Multiple Sclerosis (MS). Method: This preliminary version of the dissertation was structured in two articles. The first study (1) is an integrative review of 18 scientific publications on the use of vHIT as an important tool in the evaluation of the RVO of individuals with CNS diseases. The second study (2) was constructed in a series format of three clinical cases with a medical diagnosis of MS. Results (1): In relation to the results found in vHIT, the RVO gain was reduced in most studies. It was also observed the occurrence of hidden and evident refixation saccades, the presence of spontaneous and semi-spontaneous nystagmus and, in some articles, alteration in the RVO with and without visual optimization and, in the tests deviation of inclination and saccadic chase. Expected results (2): It is expected that the study will contribute to the identification of possible changes in the peripheral and / or central vestibular system, through vHIT, and allow to associate them with the neurological findings of individuals with MS.
