Cerebral infarction is a disease that often occurs in the elderly, with high morbidity, high recurrence rate and high disability rate. The treatment of cerebral infarction in the elderly should choose the best treatment method according to different onset periods, etiology and pathogenesis. Ultra-early stage: treatment of revascularization should be carried out as early as possible to improve the blood supply in the ischemic area by means of restoring blood flow to achieve the purpose of saving brain cells. At present, there are various treatment methods, such as intravenous thrombolysis (rt-PA thrombolysis within 4.5 hours of onset and urokinase thrombolysis within 6 hours of onset), arterial thrombolysis and intravascular intervention to retrieve emboli. Acute phase: In the acute phase of cerebral infarction, the condition is unstable and the infarction is easy to progress and aggravate, so it should be hospitalized, and the cause of cerebral infarction should be clarified as soon as possible during hospitalization, and corresponding treatment measures should be taken for the cause: such as antiplatelet aggregation and lipid-lowering plaque stabilization therapy for patients with atherosclerosis, and anticoagulation therapy for patients with atrial fibrillation. This is complemented by comprehensive treatment measures such as improving cerebral circulation and nourishing brain cells to try to save brain tissue and preserve neurological functions. Patients with severe disease are treated with neurological monitoring. Recovery period: Patients in recovery period mainly focus on neurological function recovery and control of risk factors, and rehabilitation therapy should be actively carried out, which can be accompanied by comprehensive treatment measures such as Chinese medicine and acupuncture to restore damaged neurological functions and alleviate sequelae. Posterior period: rehabilitation treatment is still the focus, maintaining a good state of mind, strengthening the training of daily living ability and improving the self-care ability of seriously ill patients, meanwhile, attention should be paid to improving lifestyle, controlling risk factors and actively preventing recurrence. In conclusion, there is no absolutely effective treatment for cerebral infarction in the elderly. At present, ultra-early thrombolysis and endovascular intervention within the time window is the best treatment, however, this time is very limited, and the treatment of cerebral infarction should be individualized and comprehensive for the etiology, onset time and other treatment options.
