How many types of strokes are there?
There are three main types of strokes: ischemic, hemorrhagic, and transient ischemic attack (TIA). Ischemic strokes occur when a blood clot blocks blood flow to the brain, while hemorrhagic strokes happen when a blood vessel ruptures, causing bleeding in or around the brain. TIAs, often called "mini-strokes," are temporary interruptions of blood flow that typically last only a few minutes but can indicate a higher risk of a future stroke. Each type requires different treatments and response strategies.
What are two ways that a Cerebrovascular Accident can occur?
A stroke can occur in two ways. In an ischemic stroke, a blood clot blocks or plugs a blood vessel or artery in the brain. About 80 percent of all strokes are ischemic. In an hemorrhagic stroke, a blood vessel in the brain breaks and bleeds into the brain. About 20 percent of strokes are hemorrhagic.
What are the Causes of cerebrovascular accident?
Cerebrovascular accidents (CVAs), or strokes, can be caused by two primary mechanisms: ischemic and hemorrhagic. Ischemic strokes occur when a blood vessel supplying blood to the brain is obstructed, often due to a blood clot, atherosclerosis, or embolism. Hemorrhagic strokes arise from the rupture of a blood vessel, leading to bleeding in or around the brain, often due to high blood pressure, aneurysms, or arteriovenous malformations. Additional risk factors include diabetes, smoking, obesity, and high cholesterol.
What cardiovascular disorders are the direct result of blood clots?
Some cardiovascular disorders that can result from blood clots include heart attacks (myocardial infarctions), strokes (ischemic strokes), and deep vein thrombosis (clots in the veins, usually in the legs). These conditions can be life-threatening and require prompt medical attention.
What is ischemic stroke?
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.
What are the 2 different types of stroke?
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.

What is the difference between an ischemic and hemorrhagic stroke?
The ischemic stroke means that there is lack of blood flow (due to a clot) to part of the brain causing that part to lose cells. The hemorrhagic stroke occurs when a blood vessel breaks and it causes bleeding. About 90% are ischemic strokes.In the second type, oxygen- and nutrient-rich blood is prevented from reaching the brain cells beyond the point of rupture. In addition, leaked blood can irritate and harm the brain cells in the areas where it accumulates. This can make this type more deadly.
Action of anticoagulant in transient ischemic attack?
Anticoagulants serve to prevent clots from forming or becoming larger. During a TIA, a small blood clot has usually gotten itself stuck somewhere in the brain. TIA's usually pass, but without an anticoagulant it is possible that the clot could "snowball" into something much larger that could become stuck and cause a full on ischemic stroke. Therefore, anticoagulants help prevent TIA's & Strokes, and also minimize their effects to some extent.
What is the term for when a blood vessel in the brain becomes clogged?
hemorrhagic strokeOR cerebrovascular accident ("CVA"). CVA can be ischemic (clot that is blocking blood flow) or hemorrhagic in nature.CVA - Cerebro vascular accidentCVA - Cerebro vascular accident
What can cerebrovascular accident be caused by?
A cerebrovascular accident (CVA), commonly known as a stroke, can be caused by two primary mechanisms: ischemia and hemorrhage. Ischemic strokes occur when a blood vessel supplying blood to the brain is blocked, often due to a clot, which can result from conditions like atherosclerosis or atrial fibrillation. Hemorrhagic strokes happen when a blood vessel in the brain ruptures, leading to bleeding, and can be caused by factors such as high blood pressure or aneurysms. Other risk factors include diabetes, smoking, and high cholesterol levels.
How are strokes?
Strokes are caused by a disruption of blood supply to the brain, often a blood clot.
