Episodic Vestibular Syndrome Syllabus
No full textThis syllabus provides an overview of Episodic Vestibular Syndrome (EVS), a clinical condition characterized by recurrent dizziness of vertigo that develops acutely (over seconds, minutes or hours); may be accompanied by nausea/vomiting, gait instability, nystagmus, or head-motion intolerance. Disease/Diagnosis: Episodic Vestibular Syndrome (EVS)
Peripheral Lesion with Direction-Fixed Nystagmus
No full textTypical spontaneous nystagmus associated with acute peripheral vestibular lesions is dominantly horizontal in vector and generally beats in one direction regardless of the eye position within the orbits. The nystagmus is usually present in the primary position, increases in gaze toward the direction of the fast phase, and decreases or disappears completely in gaze toward the direction of the slow phase. This pattern of vestibular nystagmus is said to obey "Alexander\u27s law" (Video 2a-direction-fixed left-beating nystagmus in a patient with acute peripheral vestibulopathy). Disease/Diagnosis: Nystagmus
3-Component H.I.N.T.S. battery
No full textDescribes the 3-Component H.I.N.T.S. (Head Impulse, Nystagmus, Test of Skew) battery. A wide-angle view of the tests is followed by a close-up view. Please note that in the wide-angle view, the order of the tests is as would be typically conducted in practice (searching first for spontaneous nystagmus and skew deviation, prior to repeatedly rotating the patient\u27s head for the horizontal head impulse test, which could influence the results of the prior two tests). In the close-up view, the tests are conducted in the order suggested by the acronym (purely as a memory aid). Viewers should also note that in the close-up view, the alternate cover test was not demonstrated with ideal technique, since the patient\u27s right eye was incompletely occluded by the examiner\u27s hand during testing (this represents an artifact resulting from suboptimal examiner positioning during videography).EXAMhints; IC-B8cvi-head-impulse-nystagmus-test-of-ske

A New Approach to the Dizzy Patient
No full textBest evidence suggests that a shift in emphasis in clinical assessment away from dizziness type and towards dizziness timing and triggers will probably yield more accurate and reliable diagnostic results, particularly for patients presenting with new, acute dizziness symptoms. This paper describes the "triage, timing, triggers and telltale signs" framework for assessing acute dizziness in patients

Central Lesion with Direction-Changing Nystagmus
No full textWith central causes of acute vestibular syndrome, it is not uncommon for the nystagmus to have a gaze-evoked component due to failure of gaze-holding circuits in the cerebellum or brainstem. In such instances, the nystagmus may reverse direction when the patient looks in the direction of the slow phase (Video 2b-direction-changing nystagmus; spontaneous left-beating nystagmus in primary and left gaze with reversal in right gaze in a patient with acute cerebellar infarction).
