What is the cause of intracranial ischemia?

There are many causes of intracranial ischemia, the most important factor is atherosclerosis. When patients develop atherosclerosis, it often causes blockage of some capillaries in the brain, which leads to a decrease in blood supply to the brain. Other tiny blood clots or increased blood viscosity are important causes of intracranial ischemia. Let us learn about it.

What is the cause of intracranial ischemia?

(1) Atherosclerosis: Temporary occlusion of certain cerebral arterioles. Once collateral circulation is established and blood flow is restored, the blood supply improves and the symptoms disappear within 24 hours. (2) Hypertension can cause cerebral vasospasm, poor blood flow, and insufficient blood supply. (3) Micro-thromboembolism is eliminated by the body’s own action and blood circulation is restored, but it may cause the same symptoms to recur. (4) Thrombocytosis causes high blood viscosity and insufficient blood oxygen content, as well as anemia, heart disease, and myocarditis, which can all cause transient ischemic attacks. (5) Hyperlipidemia. (6) Diabetes and its complications. (7) Overuse of the brain. (8) Emotionally excited. (9) Cold (usually occurs in people over 40 years old) (10) Fatigue (older people)

Clinical manifestations of transient ischemic attack

1. Sudden, transient, focal neurological deficits that recover within 24 hours without sequelae; the main symptoms of focal neurological deficits are: (1) hemiplegia, hemiplegia, decreased sensation, visual impairment, and bulbar palsy; (2) vertigo, headache, tinnitus, black spots in front of the eyes, facial numbness, limb weakness, coughing when drinking water, and slurred speech. Many of the above symptoms may last for a few minutes or hours before completely returning to normal. In a few patients, they may last for more than ten hours, but all return to normal within 24 hours. 2. Recurrent attacks The above clinical symptoms appear repeatedly. 3. The age of onset is mostly over 50 years old, with a history of heart disease and atherosclerosis.

Treatment of cerebral ischemia

1. Treatment of primary diseases such as hypertension, heart disease, and atherosclerosis. 2. Anticoagulant therapy. 3. Use vasodilators. 4. Lower blood lipids and blood viscosity. 5. Vascular surgery, including removal of the vascular endothelium and sclerotic plaques or vascular dilatation and stenting. 6. Symptomatic treatment
