Patients with left frontoparietal cerebral infarction can present with psychiatric symptoms and also with speech dysfunction. If patients have severe psychiatric symptoms, they should be given antipsychotic medication, such as oral olanzapine and low-dose mirtazapine. If the patient has speech dysfunction, rehabilitation can be carried out and started as early as possible when the condition is stable. Aggressive treatment of cerebral infarction, if it is a large infarct, thrombolytic therapy can be given super early, and antiplatelet aggregation and neurotrophic therapy are usually given when the time window for thrombolytic therapy is exceeded. If the patient is a mild cerebral infarction, the main treatment is to give nutritional nerve and antiplatelet aggregation treatment. The antiplatelet aggregation drugs commonly used in clinical practice are mainly aspirin and clopidogrel. The main neurotrophic drugs are edaravone, cytidylcholine and cerebroprotein hydrolysate. At the same time, Chinese herbal medicine can be given to activate blood circulation and remove blood stasis, and the clinical application is usually salvia, safflower and ginkgo biloba preparations.
