![]() Lateral medullary syndrome thus became synonymous with ‘Wallenberg syn-drome’. By 1922, he described 15 patients with this syndrome1. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA. syndrome and in 1901 his second case report with a postmortem description of the lateral medullary infarction from a stenosis at the origin of PICA. Symptoms include: vomiting, vertigo, nystagmus, pain and temperature sensation from ipsilateral face and contralateral body, dysphagia, hoarseness, diminished gag reflex, ipsilateral Horner syndrome ataxia, dysmetria. Patients with cerebellar dizziness and vertigo should receive multimodal treatment, including balance training, occupational therapy, and medication. CLINICAL PRESENTATION OF INJURY Wallenberg Syndrome (Lateral Medullary Syndrome) is caused by an occlusion in the PICA artery. Posturography and gait analysis can contribute to diagnostic differentiation, estimation of the risk of falls, as well as quantification of progression and treatment effects. Overlap syndromes with peripheral vestibular disorders, such as cerebellar ataxia, neuropathy, and vestibular areflexia, exist rarely. Wallenberg Syndrome (Lateral Medullary Syndrome) is caused by an occlusion in the PICA artery. Central fixation nystagmus (e.g., downbeat nystagmus), gaze-evoked nystagmus, central positional nystagmus, or head-shaking nystagmus with cross-coupling (i.e., horizontal head shaking causing inappropriate vertical nystagmus) occurs frequently. The characteristic features of the Wallenberg syndrome are: suffer from hiccups, acute vertigo, jerky eye movements (nystagmus), difficulty swallowing, vomiting. ![]() Patients with cerebellar dizziness and vertigo usually show a pattern of deficits in smooth pursuit, gaze-holding, saccade accuracy, or fixation-suppression of the vestibulo-ocular reflex. Key to the diagnosis is a comprehensive examination of central ocular motor and vestibular function. This term summarizes a large group of disorders with chronic (degenerative, hereditary, acquired cerebellar ataxias), recurrent (episodic ataxias), or acute (stroke, inflammation) presentations. Cerebellar dizziness and vertigo account for approximately 10% of diagnoses in a tertiary dizziness center. The usual symptoms of lateral medullary infarction include vertigo, dizziness, nystagmus, ataxia, nausea and vomiting, dysphagia, and hiccups.
