Diagnostic accuracy of the spontaneous nystagmus suppression test in predicting stroke

Takeaway

  • The nystagmus suppression test accurately predicts vestibular strokes when eye movements are recorded using video-oculography (VOG).

Why this matters

  • Failure of the fixation suppression test of spontaneous nystagmus is observed in some patients with vestibular strokes, but the accuracy of the test to discriminate between peripheral and central causes in patients with acute vestibular syndrome (AVS) is unknown.

  • Use of VOG in the emergency department to perform the nystagmus suppression test may lead to faster and more cost-effective diagnosis of vestibular strokes.
