I've changed my approach to say that the abnormal HIT must be seen when the head is turned quickly in the opposite direction of the fast component of the nystagmus. If you see an abnormal HIT when you turn the head in the direction of the nystagmus, that's not consistent with vestibular neuritis

Interesting take. Once you throw in horizontal, anterior and short arm posterior canal BPPV, it quickly leaves the word of medieval and is so much more 2024.
