Insufficient blood supply to the head is generally caused by cerebral vascular stenosis, which can be treated by medication such as aspirin or surgical treatment such as arterial stenting. 1. Drug therapy: blood vessel stenosis can take aspirin anti-platelet aggregation, atorvastatin lipid-lowering plaque stabilization therapy. Some patients have risk factors such as hypertension, hyperlipidemia, diabetes, etc. These patients should actively control their blood pressure, blood lipids and blood sugar to prevent further aggravation of stenosis. 2. Surgery: Patients with severe stenosis can be treated with arterial stenting or endarterectomy to improve cerebral blood supply. Patients with cerebral hemorrhagic insufficiency need to identify the cause of the disease at an early stage and follow the doctor’s instructions to carry out targeted treatment to avoid blindly taking medicines on their own.
