Vestibular Paroxysmia Dongzhen Yu 于 栋祯 Hui Wang 王慧. Vestibular paroxysmia (VP) is an uncommon paroxysmal disease, characterized by vertigo, tinnitus, and postural unsteadiness. Bell's palsy is the most common cause of facial weakness, whereas vestibular neuritis ranks second or third as the most frequent cause of sudden onset of dizziness and vertigo. Although neurovascular cross-compression (NVCC) of the vestibulocochlear nerve is believed to be the cause of vestibular paroxysmia, the mechanism remains controversial. Nystagmus and Nystagmus-Like Movements Dongzhen Yu 于 栋祯 Hui Wang 王慧 Yanmei Feng 冯艳 梅. In Vestibular paroxysmia hyperventilation induced rapid eye movements ( nystagmus) is observed as well. BPPV can affect people of all ages but is most common in people over the age of 60. Background: Neurovascular compression syndromes (NVCSs) are a group of neurological disorders characterized by compression of a cranial nerve and include trigeminal neuralgia (TN), hemifacial spasm, geniculate neuralgia, glossopharyngeal neuralgia, vestibular paroxysmia, and trochlear palsy. Calhoun et al. • The most common manifestations are trigeminal neuralgias (TN), hemifacial spasm (HFS), however, reports of vestibular paroxysmia (VP) and glossopharyngeal neuralgia (GPN) are rare.

Aims/objectives: To evaluate the diagnostic value and curative effect of. The symptoms are usually triggered by direct pulsatile compression with ephaptic discharges, less often by conduction blocks. The symptoms recurred, and surgery was performed. Chronic external pressure on this nerve from an adjacent blood vessel is thought to lead to demyelination, decreasing its firing threshold and making the nerve susceptible to excessive stimulation and causing vertigo attacks [ 4 ]. Vestibular paroxysmia was diagnosed. The efficacy of treatments for Menière's disease, vestibular paroxysmia, and. Vestibular paroxysmia is an example of a neurovascular compression which is caused by neurovascular contact between the eighth cranial nerve and a vessel. Secondary vestibular paroxysmia might especially be considered in cases with abnormal test findings like spontaneous nystagmus, abnormal head impulse test, and abnormal audiometric results, because these findings are infrequent in primary vestibular paroxysmia [2, 8, 10]. Precise history taking is the key to develop a first assumption on the diagnosis of vestibular disorders. Vestibular paroxysmia entails vestibular nerve function, microstructure and endolymphatic space changes linked to root-entry zone neurovascular compression J Neurol . Microvascular compression is one of the most common reasons for vestibular paroxysmia. ↑ von Brevern M et al. Not all cases of neurovascular contact are clinically symptomatic. The transition zone is susceptible to mechanical irritation and is implicated in neurovascular compression syndromes such as trigeminal neuralgia (CN V), hemifacial spasm (CN VII), vestibular paroxysmia (CN VIII) and glossopharyngeal neuralgia (CN IX).
