If a diabetic patient’s cerebral infarction deteriorates, it may be manifested by altered mental status, hemiparesis, sudden aphasia, and a sudden rise in blood glucose. Therefore, the deterioration of cerebral infarction in diabetic patients can be assessed in terms of mental changes, somatic function and motor status. The deterioration of diabetic cerebral infarction is not very different from the deterioration of other cerebral infarction. Diabetic patients with cerebral infarction are prone to recurrence, i.e., diabetic patients are prone to recurrent cerebral infarction after 1 cerebral infarction, and recurrent cerebral infarction mainly manifests neuropsychiatric symptoms, i.e., change in mental status, and changes in motor function, such as hemiparesis or sudden aphasia, may occur. In addition, when cerebral infarction is aggravated in diabetic patients, the patient’s blood glucose will be higher, which is a kind of stress state that can make the patient’s blood glucose even higher on the basis of the original.
