stroke Essay

Strokes are the 5th leading cause of death in the US, with one person dying every 4 minutes as a result. For African Americans, stoke is the 3rd leading cause of death.(http://www.cdc.gov/stroke/facts.htm) It is estimated that About 795,000 people have a stroke each year; about one every 40 seconds - there are many medical conditions that can cause a stroke and it is estimated that 8 out of 10 strokes can be prevented. However, there are some things that cannot be controlled when you are predisposed to

Strokes are caused by pathophysiological changes. The two major mechanisms of stroke consist of ischemia and haemorrhage. Ischemia is when there is no oxygen or not, merely enough oxygen to fuel the tissue level in the body. Haemorrhage in the brain, causing strokes can be due to non-traumatic intracerebral haemorrhage (Shah, MD, n.d.) (see appendix 1). This essay will further discuss the implications of strokes on a cellular, organ and system level. Explain the clinical presentation of the signs and symptoms of strokes and how the condition will be managed by a paramedic.

Neuroradiological imaging plays an important role in the process of diagnosing ischaemic stroke. The different imaging modalities that can be used to diagnose ischaemic stroke include computed tomography (CT), magnetic imaging resonance (MRI), and radionuclide imaging. In this article, the different modalities that contribute to the diagnostic process are discussed, with a focus on CT scan protocols.

Stroke is like a heart attack, but instead the problem is with the brain not the heart. Stroke happens when the blood that is suppose to go to the brain is blocked or reduced. When the blood supply to the brain is blocked or reduced, the brain doesn’t get enough oxygen or nutrients, which causes brain cells to die. It can also be because of smoking. Smoking creates blood clots in the artery. Stroke is the top 5 disease that caused death in the US, but for black people stroke is the top 3 disease that caused death. Stroke commonly occurs to people over the age of 65. Even though the risk of having a stroke is high over the age of 65, stroke can occur at any age. Approximately 15 million people suffer from stroke each year. 5 million of these

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.”

Smoking, drinking heavily, blood pressure, heart disease, cholesterol levels, obesity, type two diabetes, and drug usage (like cocaine and amphetamines). Most strokes occur in people aged 65 and up, however, it may also happen to small children and infants. Some things that cause strokes are unchangeable, such as gender (men are generally more affected), age, family history, or ethnicity (South-Asian and African-Caribbean people are more affected).

The article “Stroke” by Dr. Colin Tidy, explains that a hemorrhagic stroke is the least common, for it only affects thirteen percent of people but are the cause of most stroke deaths, this meaning many people die when

The three hospitals that I have chosen to compare the condition of strokes to are, INOVA Fairfax Hospital, George Washington University Hospital, and Reston Hospital Center. First of all, a stroke, occurs when blood flow to the brain is interrupted. When this happens, brain cells in the immediate area begin to die because they stop getting the oxygen and nutrients they need to function. There are two major kinds of strokes that I will be comparing among the hospitals. The first one is an ischemic stroke which is caused by a blood clot that blocks a blood vessel or artery in the brain. Then the second is a hemorrhagic stroke which is caused by a blood vessel that breaks and bleeds into the brain. People who suffer from strokes can have serious

A stroke (cerebrovascular accident) occurs if the supply of oxygenated blood to the brain is reduced or blocked. Brain cells require a constant flow of oxygen rich blood and if it is restrained, brain cells begin to die within a matter of minutes. If the stroke is severe, it will lead to long term damage in the brain and the muscles which are controlled by the portion of the brain affected (Teng,2013). The three main types of strokes are hemorrhagic, ischemic and transient ischemic attacks. Ischemic stroke is the most common and involves a blood clot formation in the cerebral arteries while hemorrhagic occurs do to a brain aneurysm or blood vessel leak. The blood spills into the brain and creates immense

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

Each minute that passes is increased cell death in the brain. This means the effect of the stroke will be more severe and have more of an impact on the person. A stroke is a medical emergency and signs should be recognized and treated abruptly. Signs of a cerebral vascular accident include decreased sensation, weakness, confusion, trouble speaking or understanding, trouble seeing or blurred vision, trouble walking, dizziness, loss of balance or coordination, or headache with no known cause. The American Heart Association (2013), has put out a saying, “ Spot a stroke F.A.S.T. ‘F’ for face drooping, ‘A’ for arm weakness, ‘S’ for speech difficulty, ‘T’ for time to call 911.” Treatment is dependent upon the onset of the symptoms, so acting fast and seeking medical attention is critical. Women may report unique symptoms such as loss of consciousness or fainting, general weakness, difficult or shortness of breath, confusion, unresponsiveness, sudden behavioral change, agitation, hallucination, nausea or vomiting, pain, seizures, or hiccups.

There are several signs that someone has had a stroke. Some of the common signs that I could think of are one side of the body has been affected. A person’s face could droop to one side, you could experience numbness in your body, muscle strength is often decreased when someone has had a stroke. Falling is also a sign of a possible stroke. I didn’t realize that your vision could be affected by this disease turns out that it can be.

According to the New York Times, “Ischemic stroke accounts for about 75% of all strokes and occurs when a blood clot, or thrombus, forms that blocks blood flow to part of the brain” (The New York Times, 2015). If a blood clot forms somewhere in the body and breaks off to become free-floating, it is called an embolus (The New York Times, 2015). This wandering clot may be carried through the bloodstream to the brain where it can cause ischemic stroke. According to Community Connect to Research, a hemorrhagic stroke occurs when a blood vessel on the brain's surface ruptures and fills the space between the brain and skull with blood or when a defective artery in the brain bursts and fills the surrounding tissue with blood. Both result in a lack of blood flow to the brain and a buildup of blood that puts too much pressure on the brain (Community Connect to Research,

To have their symptoms diagnosed, a person must first seek medical treatment. Only 20-25% of patients who are admitted to the hospital with a stroke arrive in the emergency department within 3 hours of the onset of symptoms (3). Once a doctor is able to determine what kind of stroke has occurred, it is important the appropriate medicine be given. If the wrong medicine were given to treat a stroke victim, it could result in death. Treatment for an ischemic stroke will focus mainly on restoring blood flow

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
