What is cerebral ischemic disease?
Cerebral ischemia or brain ischemia, is a condition that occurs when there isn’t enough blood flow to the brain to meet metabolic demand. This leads to limited oxygen supply or cerebral hypoxia and leads to the death of brain tissue, cerebral infarction, or ischemic stroke.
Is cerebrovascular disease an emergency?
Stroke is an emergency. Ischemic stroke is similar to myocardial infarction in that the pathogenesis is loss of blood supply to the tissue, which can result in irreversible damage if blood flow is not restored quickly.
Can cerebrovascular disease be reversed?
Although there is currently no treatment to reverse the damage that has already occurred, treatment to prevent additional strokes is very important. Medicines can be prescribed to control high blood pressure, high cholesterol, heart disease or diabetes.
How do you get cerebrovascular disease?
Cerebrovascular disease can develop from a variety of causes, including atherosclerosis, where the arteries become narrow; thrombosis, or embolic arterial blood clot, which is a blood clot in an artery of the brain; or cerebral venous thrombosis, which is a blood clot in a vein of the brain.
What are the different types of brain ischemia?
Brain ischemia can be categorized into a few different types. These include: 2 Thrombotic: This type of ischemia is caused by blockage of a blood vessel, usually due to a blood clot or a sudden spasm of an artery.
What is microvascular ischemic disease of the brain?
Overview. Microvascular ischemic disease is a term that’s used to describe changes to the small blood vessels in the brain. Changes to these vessels can damage white matter — the brain tissue that contains nerve fibers and serves as the connection point to other parts of the brain.
What is the difference between focal ischemia and global ischemic disease?
The ischemia can affect a small region of the brain, or it may affect a large region of the brain or even the whole entire brain. Focal ischemia is confined to a specific area of the brain. Global ischemia affects a wider area of the brain and usually occurs when the blood supply to the brain has been drastically reduced or stops.
What is the difference between cerebral infarction and ischemic stroke?
Glossary. Cerebral infarction – A stroke caused by interruption or blockage of blood flow to the brain; also called ischemic stroke. Cerebral thrombosis – Formation of a blood clot in an artery that supplies blood to part of the brain. Cerebrovascular – Pertaining to the brain and the blood vessels that supply it.
