Abstract:
In recent years, here are many new understandings in the definition, etiology, diagnosis and treatment of transient ischemic attack (TLA).The latest viewpoint considers that TIA is a transient episode of neurological dysfunction caused by brain, spinal cord or focal retinal ischemia, without the evidence of acute infarction. The duration of TIA is no longer the key factor, whether the existence of infarction or not is the key factor in the differentiation of TIA and ischemic stroke. Therefore ,it should emphasize the importance of neuroimaging in the diagnosis of TIA. As a neurological emergency, the risk level of TIA should be stratified and evaluated, and the active interventions should be performed.
