What is the cause of cerebral vascular insufficiency?

Insufficient blood supply to the brain is caused by the narrowing of blood vessels supplying blood to the brain for various reasons. Generally, the incidence rate of young people is low, and the incidence rate gradually increases after middle-aged and elderly people. Mostly because of cerebral arteriosclerosis. Symptoms such as dizziness, dizziness, unconsciousness and forgetfulness. Not specific.

Treatment methods can be divided into symptomatic treatment to directly improve cerebral and cardiac blood supply insufficiency and energy metabolism, and etiological treatment to prevent arteriosclerosis from progressing and eliminate vascular stenosis and occlusion. To improve blood supply to the brain and heart, it is necessary to control blood pressure reasonably, and choose various vasodilators to improve microcirculation and erythrocyte and platelet aggregation (such as nimodipine, ligustrazine, Huonaoling, Yangxueqingnao Granule, Ginkgo biloba, etc. ) improve cerebral blood circulation; Xiaoxintong, compound Danshen dripping pills, etc. Used for heart coronary insufficiency), and drugs for improving brain nutrition and energy metabolism (such as anti-aging capsules and cytidine disodium triphosphate). The progress of preventing arteriosclerosis should start with scientific and regular living habits, reasonable and rich diet nutrition and control of preventive and therapeutic drugs. Diet should be supplemented with antioxidants (more common in vegetables, fruits, beans and miscellaneous grains, which are protective substances for human brain and cardiovascular system) and unsaturated fatty acids (fish diet, nuts) that can prevent free radicals from harmful effects on human body; Use antiproliferative drugs (heparin, cyclosporine A, calcium antagonists, angiotensin converting enzyme inhibitors); Stay optimistic, use your head and do more tricks. For the atherosclerotic stenosis of carotid artery, vertebral artery and large intracranial branches that may have already formed, the ultrasonic examination of the neck and intracranial vessels suggests that after the diagnosis by MRA (magnetic resonance angiography) and DSA (digital subtraction angiography), endarterectomy, balloon dilatation and stent treatment are feasible. In addition, it should be noted that when the original symptoms suddenly worsen, or other neurological dysfunction occurs, it is necessary to seek medical advice in time to avoid serious acute cerebrovascular diseases.
