The objective was to explore the ability of head impulse-nystagmus-test of skew (HINTS) combined with ABCD2 score to identify cerebrovascular causes of dizziness. ⋯ HINTS examinations could efficiently differentiate stroke from nonstroke under the condition that patients remaining symptomatic, including spontaneous or gaze-evoked nystagmus. It is more practical to apply the combination of central pattern of nystagmus and ABCD2 ≥ 4 in ED setting. If patients were absence of central nystagmus at admission, cerebrovascular event should be a priority diagnosis when their ABCD2 ≥ 4.
