Cerebral thrombosis speech is considered to be caused by cerebral infarction in the language center of the cerebral cortex in the dominant hemisphere of the brain. Cerebral thrombosis is caused by intracranial blood vessel obstruction, resulting in ischemia, hypoxia, and even cell death of the brain tissue nourished by the blood vessel, these dead brain cells are not regenerative, which in turn affects brain function, when the infarction lesion affects the language center of the cerebral cortex of the dominant hemisphere of the brain, such as middle cerebral artery occlusion, etc., the patient will have speech dysfunction. In the acute stage of disease onset, intravenous butylphthalide sodium chloride injection can be prescribed to improve neurological deficits; at the same time, secondary prophylaxis should be carried out to prevent the formation of cerebral thrombosis again, oral aspirin enteric-coated tablets to resist platelet aggregation, atorvastatin calcium tablets to regulate lipids and stabilize the plaque, and to control the patient’s underlying diseases. Family members should communicate with the patient more, let the patient read books and newspapers, and exercise the speech function to recover. It is recommended that the patient should consult a doctor in time when there are symptoms of speech disorder and other discomforts, and standardize the treatment under the guidance of the doctor, so as to avoid delaying the condition.
