The acute cerebral infarction caused by diabetes is not much different from the acute treatment of cerebral infarction caused by other diseases, and the treatment includes the following points: 1) reduce cerebral edema by improving the cerebral circulation of patients; 2) carry out symptomatic treatment, and if the cerebral infarction is combined with infection, anti-infection treatment can be carried out to maintain the stability of the internal environment; 3) patients need to control blood sugar between 150 and 3. Patients need to control blood glucose between 150 and 180 mg/dl, which has a great impact on the prognosis of patients with diabetes-induced cerebral infarction. For patients with brain infarction caused by diabetes mellitus, in addition to the conventional brain infarction treatment, blood glucose should be monitored to maintain it in a relatively safe range.
