Thrombotic Stroke Research Papers

stroke is an acute episode of focal dysfunction of the brain, retina, or spinal cord lasting longer than 24 h, or of any duration if imaging (CT or MRI) or autopsy show focal infarction or haemorrhage relevant to the symptoms ,which is a leading cause of death and long term disability worldwide. It results from transient or permanent disruption of cerebral blood flow, leading to necrotic death of the brain tissue supplied by the affected artery. It activates an inflammatory condition in the affected area, marked by infiltration of inflammatory cells. Inflammation can induce an apoptotic cell death in the transition region between necrotic and normal tissue, so called penumbra, for a fairly prolonged period of time.[1].

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)

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).

A cerebrovascular accident (CVA), or stroke, is an abrupt stoppage of the blood supply of the brain. There are two types of stroke: ischemic stroke, a sudden blockage of arteries that lead to the brain, and hemorrhagic stroke, bursting of a blood vessel that leads to bleeding into the brain tissue (Panel et al.,1997). Due to the sudden onset that requires immediate medical care, it is often referred to as a brain attack. Stroke is the leading cause of adult disability in the U.S. affecting 800,00 people each year (Panel et al.,1997). Tests that view the brain, such as CT scan and MRI scans, as well as test that views the blood vessel that supplies the brain, such as the carotid Doppler, are used to properly diagnose for a stroke.

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

Hemorrhagic strokes occur when blood vessels to the brain leak blood or burst open, the blood puts pressure onto the brain as it spreads and fills the crevices between the skull and the brain until the person has a stroke. The leaking of blood, or the bursting open of the blood vessels can be caused by hypertension, trauma, blood thinning medication, and aneurysms (Mcintosh 13). There are two common types of Hemorrhagic strokes, the most common one is Intracerebral Hemorrhagic, and the other less common type is Subarachnoid Hemorrhagic (Mcintosh 14). In an Intracerebral Hemorrhagic brain tissue is flooded with blood when a blood vessel bursts open (Mcintosh 14). However, in a Subarachnoid Hemorrhagic stroke, bleeding occurs in the subarachnoid space (area between the brain and the tissue it covers) (Mcintosh 14). Hemorrhagic strokes are preventable as they are caused by treatable conditions such as high blood pressure (Mcintosh

A stroke happens when the blood supply to the brain is either interrupted, blocked or a blood vessel in the brain ruptures. These blockages are often caused by blood clots, which can form in the arteries connecting to the brain. When this happens, there is an insufficient amount of oxygen and nutrients going to the brain, and this causes the brain cells to die. It also is the fourth leading cause of death in the United States (U.S) today. There are three forms of stroke: ischemic strokes, hemorrhagic strokes, and transient ischemic attacks. These are also called mini-strokes.

Shortly after admission, she became unresponsive; a brain scan revealed she had suffered a total anterior circulatory stroke. Marianne's pupils are dilated and do not respond to light; she is breathing with the assistance of a respirator. Her elderly husband and

Cerebrovascular accident (CVA) or Stroke, is the rapid loss of brain function due to disturbance in the blood supply to the brain. This can be due to ischemia (lack of blood flow) caused by blockage (thrombosis, arterial embolism), or a hemorrhage. As a result, the affected area of the brain cannot function, which might result in an inability to move one or more limbs

What is a stroke? When brain cells die suddenly due to oxygen deprivation, a stroke occurs. Hemorrhagic and ischemic are the 2 main types of stroke. There are many signs and symptoms that indicate a stroke has occurred. Knowing the warning signs of a stroke and seeking immediate treatment can reduce the long term effects, improve recovery time, and avoid death. Stroke treatment is reliant on the type of stroke that has occurred. Medications along with lifestyle changes are common forms of treatment. The severity of stroke can range from minimal to severe therefore, rehabilitation time can take weeks or even years. If permanent damage occurs, treatment is aimed at adaptation and learning to live with the loss of function. There are many

Stroke is a life-threatening medical condition that occurs when the blood supply to part of brain cuts off. It is also referred to as a Cerebral Vascular Accident (CVA). There are two types of stroke ischaemic where the blood supplies stopped due to a blood clot in a blood vessel and haemorrhagic where a weakened blood vessel supplying the brain bursts. Transient Ischaemic Attack (TIA) is the condition where the blood supply of the brain is temporarily interrupted causing a “mini-stroke” often last between 30 minutes and several hours. TIAs are often a warning sign of having a full stroke in the near future (Stroke Association 2014). According to Nation Stroke Organisation UK (2015) statics stroke occurs about 152,000 times a year in the UK

Arm: If a person holds both arms out, does one drift downward? Speech: Is their speech abnormal or slurred? Time: It’s time to call 911 and get to the hospital if any of these symptoms are present” (Ellis, 2016).

The diagnosis is a cerebrovascular accident, also known as a stroke. A stroke occurs when the blood flow to cerebral vessels become disrupted from clotting or a rupture. The two types of CVA are ischemic and hemorrhagic. An ischemic stroke is the most common type. It results from a thrombosis1 or emboli2. A hemorrhagic stroke is the most fatal type of stroke. It occurs when there is bleeding into brain tissue from hypertension, aneurysms, or head injuries. Structures that are involved in a stroke would include brain tissue and cerebral vessels. A right sided stroke will result in left side paralysis, vision problems, inquisitive behavioral style, and memory loss. The right side of the brain is responsible for attention, creative, imaginative,

As stated previously, stroke occurs due to inadequate blood flow to the brain which results in cell death in that area of the brain. Blood supply to the brain comes from the internal carotid arteries (ICA), which accounts for 80% of total supply, and the vertebral arteries (VA) (Vrselja et al., 2014, p. 579). The ICA and VA, via the basilar artery, meet at the base of the brain forming a ring structure

Stroke: A more mechanical term for stroke is Cerebrovascular Accident (CVA). The term stroke itself is not clearly defined and is not a precise medical term. In simple terms, stroke ‘suffocates’ brain tissue and often produces an area of dead or dying brain tissue. A stroke always occurs in the brain and is the most common type of cerebrovascular disease. The most frequently encountered of the cerebrovascular diseases is the Cerebrovascular accident (CVA). It was earlier called apoplexy or an apoplectic attack and is now commonly referred to as stroke. Medically speaking a stroke is a “focal neurological disorder of abrupt development due to a pathological process in blood vessels” (J. N. Walton, 1994).
