A Cerebrovascular Accident (CVA), commonly known as a stroke, can occur due to a blockage in a blood vessel supplying the brain (ischemic stroke) or a blood vessel in the brain rupturing (hemorrhagic stroke). Both types can lead to a lack of blood flow and oxygen to parts of the brain, causing damage and impairing brain function.
Chronic microangiopathic ischemic changes are areas of the brain that show up during radiology, usually MRIs, that depict clotted off or ruptured blood vessels. These are usually related to other serious conditions, such as diabetes, hypertension, and high cholesterol.
There are two major kinds of stroke, ischemic and hemorrhagic. In an ischemic stroke a blood vessel becomes blocked, usually by a blood clot and a portion of the brain becomes deprived of oxygen and will stop functioning. A hemorrhagic stroke occurs when a blood vessel that carries oxygen and nutrients to the brain burst and spills blood into the brain. When this happens, a portion of the brain becomes deprived of oxygen and will stop functioning.

explain centrum semiovale representing remote small vessel disease and what does that mean in laymen terms?
A "stroke" is an illness of the brain, the equivalent of a heart attack. There are two general types of strokes. An "ischemic" stroke or a "transient ischemic attack" is a blockage of the flow of blood within the brain. This is typically caused by a blood clot within the brain. If small enough, in a "TIA", the clot is washed away or dissolved, with little aftereffects. A larger or longer-lasting blockage can cause substantial death of brain tissue. The other type is a "hemmorhagic" stroke, in which a blood vessel bursts and blood leaks into the brain.
A cerebral or brain aneurysm is a cerebrovascular disease in which weakness in the wall of veins causes a localized dilation or ballooning of the blood vessel. The bursting of an aneurysm in blood vessel can cause brain death.

No. A transient ischemic attack, also known as a "mini-stroke", is when a person has stroke like symptoms that resolve within 24 hours. I it due to a lack of blood flow to some part of the brain. Ischemic heart disease is when there are blood flow problems to the heart. It usually manifests as chest tightness or pain and shortness of breath is exertion but the symptoms can vary widely.
The most common cause of brain infarction is stroke, which is when blood supply to the brain is interrupted. A ischemic stroke occurs when a blood vessel carrying blood to the brain is blocked by a blood clot. A hemmorhagic stroke occurs when a blood vessel breaks open, causing blood to leak into the brain. The risk of stroke increases with high blood pressure, age, family history, smoking, heart disease, diabetes, and high cholesterol. Drug and alcohol abuse, bleeding disorders, and head injuries can also cause bleeding into the brain.
