When brain infarction occurs, such as sudden onset of speech impairment, numbness and weakness of unilateral or lateral limbs, it is important to seek medical attention as soon as possible. Intravenous thrombolytic therapy can be taken within 6 hours of the acute stage of cerebral infarction, especially within 3-4.5 hours, and the effect of intravenous thrombolytic therapy is the best. For large vessel occlusion lesions, bridging therapy, i.e., intravascular thrombus retrieval and thrombus pulling therapy, can also be taken. With aggressive and effective revascularization treatment, about 1/3 of patients can have rapid improvement or even complete remission of their symptoms. If intravenous thrombolysis or arterial embolization is missed, antiplatelet aggregation drugs, statins, and drugs to improve collateral circulation and protect brain mitochondria can also be applied to promote neurological recovery.
