Sinais e Sintomas Vestibulares e Doenças do Sistema Nervoso Central

Abstract: O desafio diante de pacientes com sintomas vestibulares (SV) é a distinção entre o acometimento do sistema vestibular periférico ou do sistema nervoso central (SNC), pois se tratam de etiologias com gravidade, prognóstico e conduta terapêutica diferentes. Descrever as características clínicas, vecto eletronistagmo gráficas e achados de exames de imagem de pacientes com SV e acometimento de SNC. Estudo retrospectivo, em que foram analisados os prontuários de todos os pacientes com SV atendidos em um ambulatório… Show more

“…Regarding the relationship between stroke in the posterior circulation and changes in visual preference, it is known that the cranial nerve nuclei involved in visual perception and eye movement control are found in the brainstem. Depending on the affected structures, there will be disturbances of spatial orientation, VOR, posture or neurovegetative manifestations (6,15,17) .…”

“…It is an important diagnostic tool which assists in the recognition of the cause, prognosis and monitoring of the patient's evolution (16) . In outpatient clinics for otoneurological evaluation, stroke is the most frequent etiologic diagnosis among cases of vestibular symptoms arising from impairments in the CNS, and it may reach 40% (17) .…”

“…The most common type of dizziness was imbalance, as described as dizziness triggered by central causes 7 . This corresponds to approximately 15% of the complaints of body balance disorders 20 ; however, unlike vertigo, imbalance suggests a neurological etiology 21 , which explains its high occurrence in this sample.…”

“…Vestibular testing investigates the vestibular function and its relationship with other systems, as well as the afferent and efferent fibers of the cerebellum, spinal cord and reticular formation of the brainstem 6 . Stroke is one of the most-frequent etiological diagnosis among cases of vestibular symptoms arising from impairment of the central nervous system 7 .…”

“…Thus, we understand that, in addition to the peripheral portion, the central portion of the hearing should be evaluated, since these alterations, together with vestibular dysfunctions, may be the only manifestations of diseases that affect other systems, such as the case of endolymphatic hydrops, ototoxicity, vestibular schwannoma, cases of traumatic brain injury, among others (6) . Also, changes in the vestibular system may be indicative of several Central Nervous System pathologies (7).…”
