Many elderly people with hypertension and diabetes may have experienced sudden weakness of one limb, slurred speech, and disobedience of limbs, which may be relieved after a few minutes or several minutes, but they may not pay attention to it at that time and regret it only when cerebral infarction occurs later. The above symptoms of the patient were considered to be the symptoms of stroke caused by transient vascular blockage, and the symptoms were relieved due to the subsequent autolysis of the thrombus and vascular patency again, so this disease is a precursor of cerebral infarction, which must be taken seriously. “When transient ischemic attack occurs, oral aspirin and statin should be taken in time. During the attack, blood pressure should not be actively controlled to avoid aggravation of ischemic infarction.
