Types Of Strokes : A Cerebral Vascular Accident

     If doctors agree that a stroke has taken place, they may do other tests to determine where the stroke occurred, how large of an area is damaged, and how the blood flow with in the brain has been effected; they do this by taking a CAT scan. They may also take an ECG to determine if there is any heart disease that may have caused the stroke. In addition, they take tests to see if the patient has high blood pressure or they may test the arteries themselves because this is a major cause of stroke in most people. Catheterization, injecting dye into the arteries, and blood tests are the most common tests done. A high glucose level in the blood may reveal diabetes and high blood fats indicate thickened red blood and arteriosclerosis. There may also be a high level of red blood cells, changing the consistency of the blood. These conditions must be treated to prevent further strokes.

Strokes are caused by a block in the blood supply to the brain which causes a decrease in oxygen and delivery of other important supplies which facilitate proper functioning. Fifteen million cases are reported worldwide annually, although not all of these cases are mortalities, the large prevalence of strokes ranks it as the fourth leading cause of death in the United States. (Figueroa) Because of the time sensitivity associated with the lack of resources to the brain, strokes are considered a medical emergency and early recognition of symptoms can help decrease the amount of damage caused . Although strokes do not always cause death, strokes most often leave the individual with some physical and cognitive impairment.

* Cerebrovascular Disease: More commonly known as stroke cerebrovascular disease can be cause by either a colt or blockage that cuts off blood flow to a part of the brain or by haemorrhage. In both cases there is damage or death of the brain tissue that can cause paralysis, speech disorder, swallowing problems and immobility. People with diabetes and high blood pressure are at higher risk of stroke.

In many cases, strokes can be diagnosed, prevented and treatable. Symptoms of a stroke can occur quickly and may cause: sudden numbness, tingling, or weakness, or paralysis in your face, arm, or leg, especially on one side of your body. Sudden: vision changes, trouble speaking (slurred speech), confusion or trouble understanding simple statements, problems with walking or balance, severe headache. It's recommended to call a doctor or 911 even if these symptoms last for a short amount of time because a transient ischemic attack, or mini stroke may have occurred. The transient ischemic attack may be a precursor to a stroke occurring soon. Catching these symptoms can dramatically increase chances of prevention additional damage to the body (2).

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.

Often times, doctors will typically call a stroke a “brain attack” because the events that transpire resemble those that occur during a heart attack (Wang and Aamodt, 2010). Blood supplies a constant source of oxygen to the brain. However, a stroke occurs when that blood supply to any given part of the brain is suddenly ceased. If the blood supply to the brain is suddenly interrupted this leads to the deprivation of oxygen and glucose to that area. The brain cells that are prevented from acquiring these substances, especially oxygen, will be quickly killed off. Strokes can be categorized into two classes: Ischemic and hemorrhagic strokes (Lindley, 2008).

A stroke is a condition which is characterised as loss of brain functioning due to an interruption in the blood flow to the brain (Buzzard, 2013, pg. 5). There are two types of strokes, ischaemic and hemorrhagic strokes (Buzzard, 2013, pg. 6). Ischaemic strokes are the most common type of stroke (Gomes & Wachsman, 2013). This type of stroke occurs due to an insufficient flow of blood to the brain, which is usually caused by an artery blockage (Gomes & Wachsman, 2013). Hemorrhagic strokes are due to hypertension and may be caused by medical problems or blood vessel abnormalities (Gomes & Wachsman, 2013). The strokes severity and location of the brain that is affected determines the impact of the stroke in an individual (Gomes & Wachsman, 2013).(Gomes, 2013)

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.

Stroke previously known as Cerebrovascular accident is well-defined as ‘an abrupt cessation of cerebral circulation in one or more of the blood vessels distributing the brain. Due to the interruption or diminish of oxygen supply causes serious damage or necrosis in the brain tissues (Jauch, Kissella & Stettler, 2005). There is a presence of one or more symptoms such as weakness or numbness or paralysis of the face, arm or leg, difficulty speaking or swallowing, dizziness, loss of balance, loss of vision, sudden blurring or decreased vision in one or both eyes and headache. Stoke is categorised into two types, Ischaemic and haemorrhagic

A stroke occurs when oxygen and nutrients are deprived from the brain due to the reduced or interrupted flow of blood to the brain. As a result, brain cells die. Symptoms of stroke may include slurred speech or no speech, difficulty with understanding, weakness or paralysis to one side of the body, facial drooping, vision problems, trouble swallowing or headache.

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

A cerebrovascular accident more commonly known as a stroke or brain attack is the term used to describe the sudden death of brain cells in a localized area due to inadequate blood flow. In order to woke the brain needs a constant supply of oxygen and nutrients. This supply is carried to the brain

What is a stroke and how is it related to the aging brain? A stroke happens when the blood supply to your brain is interrupted or it is reduced, depriving the brain tissues of oxygen and food (Bendheim, P.E. (2009). Within minutes of a stroke brain cells begin to die. Early action can minimize brain damage and potential complications. A stroke can cause temporary or permanent disabilities, depending on how long the brain suffers the lack of blood flow (Perlmutter, David. (2004). Some complications after a stroke are; paralyzation (loss of muscle movement), memory loss, and trouble talking. Paralyzation is due to the lack of blood flow to the brain, a patient can lose movement in one side of the body. Stroke can damage too many parts of the brain, and it can start an early brain aging. A stroke can cause a patient to loss control over the way muscles in the mouth move, have difficult talking and eating (Bendheim, P.E. (2009). But one can try to prevent a stroke by taking care of their high blood pressure, high cholesterol, and smoking.

STROKE and TIA happen when a blood vessel that feeds the brain gets blocked or bursts. Then that part of the brain can’t work and neither can the part of the body it controls. Major risk factors for stroke include: • High blood pressure • Smoking • Diabetes • High cholesterol • Heart disease • Atrial fibrillation (abnormal heart rhythm) Call 9-1-1 to get help fast if you have any of these warning signs of stroke and TIA: • Sudden numbness or weakness of the face, arm or leg, especially on one side of the body • Sudden confusion, trouble speaking or understanding • Sudden trouble seeing in one or both eyes • Sudden trouble walking, dizziness, loss of balance or coordination • Sudden, severe headache with no known cause Take a few minutes to write your questions for the next time you see your healthcare provider. For example: Talk to your doctor, nurse or other healthcare professionals. If you have heart disease or have had a stroke, members of your family also may be at higher risk. It’s very important for them to make changes now to lower their risk. Call 1-800-AHA-USA1 (1-800-242-8721), or visit heart.org to learn more about heart

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
