Cerebral Vascular Accident ( Cva )

Cerebrovascular Accident- condition in which brain tissue is deprived of blood supply.  The most common stroke symptoms are:

The diagnostic process for a formally diagnosing Cerebral Vascular Accident (CVA/stroke), would consist with a number of test including a physical exam and questions regarding your family history of strokes, any signs or symptoms that may have been present before the patient had the stroke. The physician would also order a few tests like a MRI, CT scan, Cerebral Carotid ultrasound, Cerebral Angiogram and an Echo Cardiogram. The physical exam is important to listen to the hearts sounds, take your blood pressure and also use a ophthalmoscope ( a scope to look in your eyes, ears and nose) to see if there are any cholesterol crystals behind the eyes("Diagnosis - Stroke - Mayo Clinic," 2015). A MRI, uses radio and magnetic waves to show a detailed

A stroke occurs when the blood supply to the brain is blocked. The tissue does not get enough of oxygen and nutrients within minutes, the brain cells begin to die. A stroke is a medical emergency, and prompt treatment is crucial. The good news is a stroke can be treatable and is more preventable. More people live longer now than in the past years. Stroke is known as the silent killer. Many people ignore the symptoms and cause more damage to their body. People with stroke have trouble speaking and understanding, paralysis or numbness of the face arm or leg. If you ever encounter anyone with these systems, please call 911 imminently for help.

A CVA occurs when a part of the brain is damaged or destroyed due to an interruption of blood flow to the area resulting in brain cell death (Martini, Nath & Bartholomew 2015 pp. 496-470).There are two main types of a CVA, Ischaemic stroke and Haemorrhagic stroke (AIHW 2013). The most common cause of stroke is ischaemic, which can be caused by embolism/thrombosis (AIHW 2013). An embolism/thrombosis occurs when there is a clot in an artery or vein, which stops blood flow to the brain (AIHW 2013). A haemorrhagic stroke is when an artery ruptures and bleeds into the surrounding brain tissue (AIHW 2013). This form of stroke occurs when blood pools and forms a clot therefore putting pressure on the area of the brain depriving it of oxygen and nutrients it needs to remain healthy (AIHW 2013).

Ischemic stroke is the blockage of blood vessels in the brain as a result of blood clots (thrombi), causing the portions of the brain nourished by the vessel and its tributaries to be starved of nutrients, poisoned, and to eventually die (“Symptoms

An ischemic stroke is typically caused by a thrombosis, which is a blood clot or an embolism, when the blood clot detaches and infiltrates the blood stream.

According to our American Red Cross Nursing Assistant text a cerebral vascular accident, C.V.A., or stroke occurs when blood flow to a part of the brain is interrupted. The loss of blood supply results in the death of brain cells. (Page 91) When your brain starts to die the bodily functions the brain controls can be affected. The affected bodily functions depend on what part of the brain does not receive oxygen. Web MD says damage “can occur within 3-4 minutes if not treated.”

Hemorrhagic stroke occurs when a blood vessels in the brain leaks or ruptures. Bleeding from the ruptured brain artery can either go into the substance of the brain or into the various spaces surrounding the brain. The two types of hemorrhagic stroke are Intracerebral and Subarachnoid hemorrhagic.

Ischemic Strokes (caused by blood clots) - The most common cause of a stroke is a blood clot (thrombus) which is formed within a blood vessel of the brain. Embolism can also occur when a blood clot lodges itself in an artery causing a blockage, disabling oxygen rich blood from travelling to the brain. A heart attack (myocardial infarction), where the heart valve is damaged and an irregular heartbeat (atrial fibrillation) occurs, can cause blood clots which may eventually reach the brain.

Stroke is often related to other genetic diseases or disorders. Stroke occurs by blood flow being interrupted to the brain by either a clot or a bleed on the brain. The brain cells die quickly if blood flow is blocked (Centers of Disease Control and Prevention, 2016a). Ischemic stroke occurs when blood flow is blocked by clots or particles (CDC, 2016a). Hemorrhagic stroke occurs when the brain has a bleed from blood vessels bursting (CDC, 2016a). Stroke can leave individuals with deficits and dependent on others for care. Stroke can cause death.

A stroke is when the blood flow to the brain is cut off and oxygen cannot get to the brain. This results in areas of the brain not being able to work

A stroke is a type of cardiovascular disease that affects the cerebral arteries, those blood vessels that carry blood to the brain. A stroke occurs when one of those blood vessels in the brain is obstructed or ruptures flooding the brain with blood. Depriving blood and oxygen to the brain results in those immediate cells death, causing the brain not to function properly. Once parts of the brain stop functioning, it can directly affect the areas of the body controlled (1).

A stroke caused by a blocked artery by a blood clot or bursting of a blood vessel because of uncontrolled high blood pressure. There are main three types of the stroke. An ischemic stroke occurs when a blood clot blocks one of the arteries which supply blood to brain. A clot may be caused by fatty deposits (plaque) that build up in arteries and cause reduced blood flow (atherosclerosis) or other artery conditions. (mayo clinic). About 89%, strokes are ischemic strokes. Ischemic stroke includes thrombotic stroke. A thrombotic stroke occurs when a thrombus stuck in one of the arteries that supply blood to the brain. A clot build-up of fatty deposits in arteries. Another type of stroke is called the hemorrhagic stroke. This stroke occurs when a blood vessel leaks or ruptures in the brain. A bold vessel leaks or ruptures from many conditions like uncontrolled high blood pressure or overtreatment with anticoagulants and the weak spot in blood vessel walls. (mayo). Some people experience a mini-stroke it is known as a transient ischemic attack (TIA). A temporary decrease or clot stuck in a vessel in our brain causes TIA. It happens less than five minutes. This stroke does not have any symptom, because the blockage is

Strokes are severe health events that are defined as a formation of a blood clot in the brain that starves a section of the brain. (National Stroke Association, 2016) When this occurs, it causes the tissue downstream of the blood vessel to die. The way these clots form by way of atherosclerosis. In short, it is the build-up of plaque and cholesterol in the blood vessels. This plaque then ruptures and causes a blood clot to form. In many cases the clot forms in another region of the body and travels to the smaller blood vessels in the brain and becomes lodged. (NSA, 2016) There are two main types of strokes that can occur. The first is known as an ischemic stroke. It occurs when a blockage occurs in a blood vessel that is carrying oxygenated

This is all very similar to heart attack, but it occurs whenever a cerebral artery becomes blocked. To break it down, the stroke involves the blood flow through the body, but instead of putting a burden on one’s heart, it affects the brain. The brain is responsible for all voluntary functions of the body such as finger, arm, leg, and toes movements. It is also important for involuntary functions of the body, to include blinking and constant breathing, while awake or asleep. I named these few functions (even though there are millions of functions that our brains perform) to show the importance of the brain. When a stroke occurs it cuts off oxygen and blood supply to the many tissues in the body. Cutting off these functions can cause permanent paralysis or certain parts of the body, loss of motor functions, or it can be
