Objective  To explore the clinical and imaging features of patients with acute dizziness and assess their associations with 3-month prognosis. Methods  We enrolled adult patients with a chief complaint of acute dizziness, who were admitted to the Neurological Clinic at the Emergency Department of West China Hospital, Sichuan University between January 1st and May 31st 2022. We collected clinical and imaging features at baseline for each patient. The primary outcome was recurrent dizziness within 3 months after index dizziness. Secondary outcome was stroke within 3 months after index dizziness. Results  A total of 1 322 patients who visited the Neurological Clinic were included, of which 617 (46.7%) had a chief complaint of acute dizziness. Among 222 patients who performed emergent brain and neck CT angiography, 1 patient presented with intracerebral haemorrhage. Among the remaining 221 patients, 206 patients completed 3-month follow-up, with 76 patients reported recurrent dizziness and 7 patients had stroke (6 ischaemic, 1 hemorrhagic). The multivariate logistic regression showed that chronic dizziness duration and parenchymal hypodensity on brain CT were each associated with a higher risk of recurrent dizziness. Compared with those who did not report stroke, the stroke patients were more likely to present with hypertension, headache symptoms, and exhibit parenchymal hypodensity on baseline CT (P<0.05). Conclusions  In patients with acute dizziness, those with chronic dizziness duration and parenchymal hypodensity on baseline CT were associated with a higher risk of 3-month recurrent dizziness. Acute dizziness patients experiencing 3-month stroke often have hypertension, headache symptoms, and parenchymal hypodensity on baseline CT.
