Simple cerebral blood supply insufficiency generally does not have a significant impact on the patient’s life expectancy, and can not simply say how long the patient can live.
Cerebral blood supply insufficiency is mostly seen in middle-aged and old people, and patients often have different degrees of stenosis of blood vessels in the head and neck, resulting in a reduction of blood supply to brain tissues, but most of them do not cause focal neurological deficits, and some of the patients may experience dizziness, headache and other uncomfortable symptoms, which will not have an impact on the patient’s life expectancy.
If the degree of stenosis of head and neck blood vessels is gradually aggravated, the blood supply to brain tissues is further reduced, and the collateral circulation is not able to compensate, ischemic cerebrovascular disease, such as cerebral infarction, etc., with focal neurological deficits such as numbness and weakness of unilateral limbs, which may threaten the patient’s life if it involves the important vital center.
Patients with cerebral blood supply insufficiency should seek timely medical treatment, standardized treatment under the guidance of the doctor, quit smoking and alcohol restriction, regular and appropriate physical exercise, control of blood pressure, blood glucose, blood lipids and other risk factors for cerebrovascular disease, and if necessary, oral medication, such as ginkgo biloba, aspirin and so on.
