Clinically, diabetic patients with prolonged substandard blood glucose control can cause diabetic macrovascular complications. If patients are also combined with hypertension and hyperlipidemia, the risk of atherosclerotic plaque formation increases significantly. Once the plaque in the patient’s neck is dislodged, it can lead to the occurrence of cerebral thrombosis. The symptoms of cerebral thrombosis are related to the site of cerebral infarction, and the clinical manifestations are numbness of half limbs, loss of muscle strength, slurred speech, and choking on water. Some patients exhibit non-neurological symptoms such as nausea and vomiting, and some patients exhibit intermittent seizures, which require improvement of cranial MRI for clear diagnosis. If a new cerebral infarct lesion is present in the cranial MRI, treatment requires the administration of aggressive antiplatelet aggregation medications, such as aspirin and clopidogrel. Plaque-stabilizing medications, such as statins, are given. Give drugs to improve the circulation, such as prostilbestrol, and give drugs to nourish the brain nerves.
