Ischemic cerebrovascular diseases originating from the brain's posterior circulation account for 20-25% of cases. Among patients diagnosed with cerebellar infarction, 10% present with isolated dizziness as their sole symptom. Notably, posterior circulation strokes and cerebellar infarcts are misdiagnosed 2 to 4 times more frequently than anterior circulation strokes. In 2017, Kuroda et al. developed the TriAGE+ score to assess stroke risk in patients presenting with dizziness. This study aims to externally validate the TriAGE+ score, focusing on its safety, applicability, and reliability in predicting cerebrovascular disease in the emergency department.
