3 Central Lesion with Direction-Changing NystagmusWith 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 ph...Image/MovingImage
4 Peripheral Lesion with Direction-Fixed NystagmusTypical 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...Image/MovingImage

7 3-Component H.I.N.T.S. batteryDescribes 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 nystagm...Image/MovingImage
8 Skew Deviation and the Ocular Tilt ResponseThe objectives of this presentation are to provide an understanding of the current use of the terms "ocular tilt reaction" and "skew deviation," to create some familiarity with the anatomic and physiologic substrate of ocular tilt and skew, and to demonstrate how to distinguish between skew and isol...Text; Image
9 Acute Vestibular Syndrome SyllabusThis syllabus provides an overview of acute vestibular syndrome, a clinical condition condition characterized by dizziness of vertigo that develops acutely (over seconds, minutes or hours); may be accompanied by nausea/vomiting, gait instability, nystagmus, or head-motion intolerance . It describes ...Text
10 A New Approach to the Dizzy PatientBest 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 t...Text
11 Episodic Vestibular Syndrome SyllabusThis 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 intoleranceText
12 Neuro-Vestibular Examination SyllabusThis syllabus provides an overview of the neuro-vestibular examination, including descriptions of the Head Impulse Test, VOR Cancellation Test, Dix-Hallpike Test and the Modified Epley Maneuver.Text
