Essay on Stroke

It is “a sudden loss of function resulting from disruption of the blood supply to a part of a brain” (Hincle & Cheever, 2014). The type of stroke Patient S experienced was assumed to be from hyperlipidemia. An atherosclerotic plaque can form in the large blood vessels in the brain. When the plaque become big enough, it can rupture or a small bit may break off and flow into small arteries, which may block the smaller artery. If the artery is occluded, blood cannot flow to certain parts of the brain and an ischemic stroke can occur. Hypertension is a major risk for strokes as well as atrial fibrillation. These diseases increase the risk of an emboli or plaque

Intracerebral drain stroke is a seeping inside the mind tissue because of the burst of veins, record 10% of all stroke cases. Generally coming about because of hypertension is the primary driver, coagulation figure issue, anticoagulant and thrombolytic treatment, cerebrum tumor, injury, and a burst of an aneurysm. ICH generally happens amid a time of movement, and has a sudden onset that advance with minutes to additional keeping in mind the end goal to create draining inclination figure (7), (Lewis, et al. 2014 and Ignatavicius & Workman, 2015b).

Stroke also known as cerebrovascular accident (CVA), cerebrovascular insult (CVI), or a brain attack. A brain attack is the loss of brain function by the cause of disturbance in the blood supply to the brain. This disturbance occurs due to either one of two causes which are ischemia (lack of blood flow) or a hemorrhage (high increase of blood flow directly into brain; parenchyma or into the subarachnoid space which surrounds the brain with tissue). Ischemia is a formation by a blood clot that is inside of a blood vessel located in the circulatory system called thrombosis or arterial embolism; which is a rapid interruption in the supply of blood flow to an organ or body part due to a clogged artery blocking the blood flow. Thrombosis is a

A stroke happens when there is a problem with the blood supply to the brain such as a clot or spasm blocking cerebral vessels. There are two types of

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).

Hemorrhagic strokes may be intracerebral (within the brain) or subarachnoid which occur from an aneurysm or atypical blood vessels.

The second type of embolism, a Brain embolism, occurs when the blood clot becomes lodged in a blood vessel in the brain. The lodged clot can result in an ischemic stroke or a Transient Ischemic Attack (TIA). An Ischemic stroke (which makes up for 85% of all strokes) is caused when the blood supply to the brain is interrupted by a clot, causing cells of the brain to be deprived of oxygen and nutrients ultimately leading to cell death. Typical symptoms involving a stroke are trouble speaking and difficulty understanding speech, paralysis or numbness of the face, leg, and arm on one side of the body, trouble with vision in one or both eyes, an abrupt, severe headache that is accompanied by vomiting and dizziness, and trouble with walking and coordination.

A stroke occurs when there is a disruption of blood flow within the brain. A stroke can occur in two ways, one is a blood clot forming which can block a vessel in the brain causing an ischemic stroke. Another way is having a leakage or burst in a blood vessel inside the brain, causing a brain bleed (hemorrhagic stroke). The population stroke most often affects are the African American, Alaska Native, and American Indian populations. Individuals with specific risk factors may also be at a greater risk of getting a stroke. These risk factors include high blood pressure, diabetes, heart diseases, smoking, and family history. There is no specific age of onset for stroke, but the risk of a stroke occurring does increase as an individual gets older.

Or a cerebral embolism occurs when a clot has travelled into the cerebral circulation which causes local cerebral infarct. Hemorrhagic strokes are caused by blood leaking into the brain because of the damaged vessel in the brain rupturing. Bill has suffered a right hemisphere stroke which can lead to paralysis on this left side, behavioral changes, vision and memory loss stated in Brainfoundation.org.au, (2016).

A stroke is a “Brain attack” that can happen to anyone at any time. This attack occurs when the blood flow to an area of the brain is cut off. Many may ask the question what causes a stroke. A stroke is caused when the blood flow to an area of the brain is cut off the brain cells are deprived of oxygen and begin to die. Studies show that a stroke occurs every 40 seconds and in every four minutes someone dies from a stroke. (Association) There are three different types of strokes Ischemic stroke, Hemorrhagic Stroke, and Transient Ischemic stroke, and they can all have a huge impact on your health.

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

(Mayo Clinic Staff, 2016) Within the category of an ischemic stroke, the 2 sub-strokes are: thrombotic and embolic strokes. “A thrombotic stroke occurs when a blood clot forms in one of the arteries that supply blood to (the) brain…may be caused by fatty deposits that build up in arteries and cause reduced blood flow (Mayo Clinic Staff, 2016)”. On the other hand, “An embolic stroke occurs when a blood clot or other debris forms away from your brain…and is swept through (the) bloodstream to lodge in narrower brain arteries (Mayo Clinic Staff, 2016)”. The second category of stroke is the hemorrhagic stroke, which occurs, “…when a blood vessel in (the) brain ruptures (Mayo Clinic Staff, 2016)”. Within this category of stroke, again possess 2 sub-categories: intracerebral and subarachnoid hemorrhages. An intracranial hemorrhage is when a blood vessel in the brain ruptures and leaks it’s contents into the surrounding brain tissue (Mayo Clinic Staff, 2016); conditions such as, “high blood pressure,

The blood vessel in question may be a branch of a middle cerebral artery, producing the symptoms described above. In other cases, the vessel may be located deep inside the brain, causing a so called lacunar infarct, which can result in sensory or motor deficits (but seldom both). Hemorrhagic strokes can also result from head trauma or therapy with anticoagulant drugs such as warfarin. Currently, there is no specific treatment for most hemorrhagic strokes other than supportive care followed by occupational, physical, and speech therapy. In the appendix of this book, I propose a novel approach to acute stroke management.

In Haemorrhagic the rupture of a cerebral blood vessel causes bleeding into the subarachnoid space or brain tissue.
