Ahead of Print. Vestibular neuritis (VN) is one of the most common causes of acute vestibular syndrome (AVS). Quantifying the vestibulo-ocular reflex (VOR) gain by the video Head Impulse Test (vHIT) could provide amplitude (10Y20 degrees), unpredictable head move-ment in the plane of the horizontal canal while the subject fixates on a central target (9). Clinically, a unilaterally abnormal HIT is found in approximately 95% of patients with vestibular neuritis (1), whereas it is found in less than 10% of patients with stroke (generally those causing is- Head impulse test — to detect unilateral hypofunction of the peripheral vestibular system, and to help differentiate between cerebellar infarction and vestibular neuronitis.
Are there any CNS signs on exam? Any gait or truncal ataxia? If you answer yes to any of these questions, evaluate for a central cause.

Methods: Thirty-three cases of vestibular neuritis (VN), 96 patients with other acute vertigo (AV), and 50 cases of normal controls used vHIT to quantitatively test a pair of horizontal Diagnostic Value of Video Head Impulse Test in Vestibular Neuritis: Methodological Issues.

It may be mimicked by central causes, including stroke, but in the hands of subspecialists, the HINTS+ (Head Impulse, Nystagmus, Test of Skew, where + is the addition of a bedside finger rub assessment of hearing) examination can detect a central cause of the acute vestibular syndrome with a very high sensitivity and specificity (both >95%). Background: This study assesses the value of the video head impulse test (vHIT) for early diagnosis of vestibular neuritis (VN) among acute vertigo. Left-beating nystagmus (LBN) was only noted in left gaze, but with fixation-removed, there was clear LBN in primary position that increased with head-shaking and vibration. The head impulse test (HIT) was abnormal to the right: when her head was moved quickly to the right (while being asked to fixate on the examiner's nose), due to a deficient vestibulo-ocular reflex on the right, the eyes initially moved to the right with the head.
We rec … The head impulse test may be positive (but it may also be positive for other peripheral causes of vertigo and so cannot be used to differentiate between them). It is useful for helping to differentiate vestibular neuronitis from a central lesion. Hearing and otoscopy are normal on examination. eye-movement signs at the bedside (head impulse, nystagmus, and test-of-skew [HINTS[) even outperforms the MRI in differentiating peripheral from central causes of AVS . Among these tests, the bedside head impulse test (bHIT) is the single best predictor for a stroke in AVS . A bilaterally intact vestibular ocular reflex (VOR) Article.
