Abstract
Cerebrovascular disease is estimated to account for 4% of patients with vertigo or dizziness. However, cerebrovascular disease is an important and serious cause of vertigo. In these cases, since cerebrovascular events mainly
involve the brainstem and cerebellum, most cases show various neurological signs, such as nystagmus, ataxia,
dysarthria, dysphagia, diplopia, facial and limb weakness. In cases without these neurological signs (isolated
vertigo), sudden onset, risk factors for stroke, constant severe vertigo/dizziness in supine position, standing and
gait inability, and nystagmus (bilateral/vertical) are considered as features of vertigo due to cerebrovascular
disease distinct from peripheral vertigo
