Isolated dizziness and vertigo due to vascular mechanisms are frequently misdiagnosed as peripheral vestibulopathy or vestibular migraine. For diagnosis of strokes presenting with an acute prolonged (≥ 24 hours) vestibular syndrome, findings on clinical examination, such as HINTS (negative head impulse tests, detection of direction-changing gaze-evoked nystagmus, and presence of skew deviation), are more sensitive than findings on neuroimaging. Since HINTS alone cannot securely detect anterior inferior cerebellar artery strokes, additional attention should be paid to the patients with unexplained hearing loss in addition to acute prolonged vestibulopathy. For diagnosis of transient (< 24 hours) spontaneous vestibular syndrome due to vascular mechanisms, the presence of associated craniocervical pain and focal neurological symptoms/signs is the clue. Even without these symptoms or signs, however, vascular imaging combined with perfusion- and diffusion-weighted MRI should be performed in patients with multiple vascular risk factors or a high ABCD2 score (age, blood pressure, clinical features, duration of symptom, and presence of diabetes).

Sleep disorders are commonly encountered in patients with vertigo. Comorbid of them is a major clinical challenge as the outcomes of both conditions are worsened by each other. The sleep and vertigo i...

The purpose of this study is to determine the potential usefulness of new functional MRI in diagnostic assessment of patients presenting with vertigo.
Vertigo is a common complaint in the Emergency Department (ED). The differential diagnosis of central and peripheral vertigo is a difficult issue that directly affects mortality. Magnetic ...
Do migrainous vertigo patients have more pathology in their vestibular system than migraine patients without vertigo? The aim of this study is to compare the vestibular system of migraine...
An illusion of movement, either of the external world revolving around the individual or of the individual revolving in space. Vertigo may be associated with disorders of the inner ear (EAR, INNER); VESTIBULAR NERVE; BRAINSTEM; or CEREBRAL CORTEX. Lesions in the TEMPORAL LOBE and PARIETAL LOBE may be associated with FOCAL SEIZURES that may feature vertigo as an ictal manifestation. (From Adams et al., Principles of Neurology, 6th ed, pp300-1)
Idiopathic recurrent VERTIGO associated with POSITIONAL NYSTAGMUS. It is associated with a vestibular loss without other neurological or auditory signs. Unlike in LABYRINTHITIS and VESTIBULAR NEURONITIS, inflammation in the ear is not observed.
Flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine H1 blocking activity. It is effective in the prophylaxis of migraine, occlusive peripheral vascular disease, vertigo of central and peripheral origin, and as an adjuvant in the therapy of epilepsy.
The force that opposes the flow of BLOOD through a vascular bed. It is equal to the difference in BLOOD PRESSURE across the vascular bed divided by the CARDIAC OUTPUT.
Secondary headache disorders attributed to a variety of cranial or cervical vascular disorders, such as BRAIN ISCHEMIA; INTRACRANIAL HEMORRHAGES; and CENTRAL NERVOUS SYSTEM VASCULAR MALFORMATIONS.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
