Clinicians should take a mechanistic approach to transient ischemic attack and stroke. Distinguishing between hemorrhagic and ischemic stroke is important and is most readily accomplished with a computed tomographic brain scan. Newer diagnostic studies are now available to help evaluate patients for a cardiogenic source of embolism. Detection of a cardiogenic source of embolism or high-grade carotid stenosis identifies stroke-prone persons in whom interventional therapy is beneficial.
临床医生应采用机制性方法来处理短暂性脑缺血发作和中风。区分出血性中风和缺血性中风很重要，而通过脑部计算机断层扫描最容易做到这一点。现在有更新的诊断研究可用于帮助评估患者是否存在心源性栓塞源。检测到心源性栓塞源或重度颈动脉狭窄可识别出适合进行介入治疗的易发生中风的人群。
