Stroke Research Paper

A stroke can be generally be defined in two types of categories. The first and most common type of stroke is called ischemic stroke. This occurs when a blood clot (cerebral thrombosis) blocks a blood vessel in the brain. Blood flow beyond the blood clot is then

There are three types of strokes that cause changes to the brain: Hemorrhagic stroke,Intracerebral hemorrhage and Transient ischemic attack (TIA). Ischemic stroke is the most common form of stroke, accounting for around 87% of strokes.

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.

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.

A stroke is a sudden stop in brain function. Approximately 25% of all people who get a stroke will have another in about five years time. The symptoms that occur are mainly affecting the nervous and digestive system, however, they may also have an effect on the other systems. Having a stroke will indeed affect the body’s functions extremely negatively. Affecting many parts of the body, strokes are devastating to the human race, killing many. The types of strokes, symptoms, and predictably will be covered.

Sometimes known as a brain attack, a stroke occurs when blood flow to the brain stops. Brain cells immediately start to die due to the lack of oxygen and nutrients they need to function. There are two types of strokes. The most common type, called ischemic stroke, is caused by a blood clot that blocks a blood vessel in the brain. The other kind of stroke, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. Stroke is the fourth leading cause of death for Americans ("What You Need to Know About Stroke," 2013). In fact, according to the CDC, more than 795,000 people in the United States have a stroke every year ("Stroke Facts," 2015). A stroke can cause great damage in the brain and lead to mild or severe

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.

1. Every 40 seconds someone in the United States has a stroke (National Stroke Association, 2014). Some symptoms related with a stroke are headache, blurred vision, trouble speaking, confusion, dizziness and numbness on one side of body. These symptoms are very important to know. Due to how common strokes are it's good to know the warning signs. For every person that dies from stroke, more than 5 times that many will survive, and for them the physical damage it causes can be enormous (National Stroke Association, 2014). Most people who have a stroke are depressed after it's all said and done. They may be paralyzed on one side, have a speech impairment or worse. When you are used to living a certain way and that suddenly changes it can be hard for people to deal with.

Ischemic Stroke tends to occur when the artery responsible to supply oxygen rich blood to the brain becomes clotted or blocked. Another type of stroke is Hemorrhagic Stroke it occurs when an artery in the brain is rupture causing it to leak. The leaks puts too much pressure on the brains cells ,which damages them. Hemorrhagic stroke is also divided into two categories : Intracerebral hemorrhage, which is the most common type of hemorrhagic stroke , it occur when an artery in the brain bursts , flooding the surrounding tissue with blood. And subarachnoid hemorrhage, which is a lest common type of hemorrhagic stroke, it occurs when there is bleeding in the area between brain and thin tissues that covers it. Last but not least is the Transient Ischemic Attack also known as TIA or sometimes call “mini stroke” . This specific stroke is different from others major types of stroke because it occurs when the blood flow is blocked for only a short period of time (no more than five minutes).

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.

A stroke occurs when there is a sudden decrease in blood flow to a localized area in the brain (Trakalo, 2015, p.1234). This can occur in different ways such as a thrombus, an embolus, a stenosis, or a hemorrhage - all of which can cause devastating neurological effects depending on the extent of ischemia and necrosis resulting from the decreased oxygen carried by the blood.

A stroke is considered a medical emergency in which prompt treatment is crucial to minimize damage to the brain and reduce the complications. There are preventative measures for strokes, which is why there are fewer deaths presently compared to years ago. Reducing the risk factors is ideal in reducing the chances of stroke occurrence. Ensuring proper weight management, exercising/ physical activity, reducing or stopping alcohol consumption, stopping smoking and stopping use of illegal drugs can help prevent the risk of a stroke. Other risk factors include family background, being older, race, and gender.

If you or a loved one has had a stroke, the road to recovery can be long and difficult. However, with in-home health services, the road is made easier. There are a variety of services that can be provided to a stroke survivor in their home to make the process less difficult. The following are only a few of the important services to aid in your stroke recovery.

Stroke or cerebrovascular accident (CVA) or brain attack is a disease that occurs when blood flow to part of brain is cut off then nutrients and oxygen can’t nourish to cells in brain which causes brain cells die and lead to many symptom for example, losing muscle control, weak muscle, a paralytic state and slurred speech that is a long term disability so it disturb daily life of stroke patients. Stroke classify in three type which are Ischemic strokes, Hemorrhagic strokes and Transient ischemic attacks (TIAs)

A stroke also known as cardiovascular accident (CVA) is a serious killer and cause of disability. It occurs when a blood vessel breaks causing an interruption of blood flow to the brain or a blood clot blocks arteries leading to brain cells beginning to die and brain damage. This process can be caused by thrombosis hemorrhage or embolism, resulting in either left side or right side hemiplegia. Strokes only effect one side of the brain (Carter, & Van Andel 2011). There are three pathological types of strokes primary intraccerebral hemorrhage, ischaemic stroke, and subarachnoid hemorrhage (Warlo, Martin, Wardlaw, & Sandercock, 2003). While dealing with a stroke their can also be a transient ischaemic attack (TIA) also know as a mini stroke. This occurs when the blood supply to the brain is blocked for a short period of time. Transient ischaemic attack acts more like a warning sign there is temporary brain malfunctions but with continued occurrence it could cause dementia (Staessen & Wang, 2001). Strokes may lead to problems with awareness, thinking, attention, learning and memory. Other problems that may occur are difficultly controlling their emotions or show inappropriate emotions which lead to a high rate of depression in stroke patients (National Institute of Neurological Disorders and Stroke, 2014). Evidence shows that after a stroke depression and anxiety are prevalent and often long-term for survivors, continuing up to five years after an incidence of stroke (Murray et
