About 3/4 of the patients with cerebral infarction will have sequelae, which means that 1/4 of the patients can have no sequelae, and these 1/4 patients are curable cerebral infarction. Whether the brain infarction can recover well depends on the following aspects: I. Whether the brain infarction received timely and effective treatment in the acute stage. Second, the location and size of the cerebral infarction. The degree of atherosclerosis of the vessels responsible for the cerebral infarction and whether there is vascular stenosis or occlusion. Fourth, the degree of establishment of collateral circulation. When you have a cerebral infarction, you should consult a doctor as soon as possible, and intravenous thrombolytic therapy can be given within 6 hours of onset, especially within 3-4.5 hours. In patients with large vessel lesions, arterial thrombus retrieval or thrombus pulling treatment can also be performed, and some patients can be revascularized, and the symptoms of cerebral infarction can be rapidly improved or even completely relieved. If the site of cerebral infarction is in a non-nerve fiber dense area, the scope of lesion is smaller, and the recovery is better after treatment. The absence of severe stenosis or occlusion of blood supply vessels of brain infarction and good compensation of collateral circulation also mean that the brain infarction will recover well after active treatment.
