Ischemic Stroke Research Paper

Stroke is the third cause of death in the United States. Stroke is the interruption of blood in the brain. According to the American heart association 730000 Americans are affected by stroke per year 160000 resulting in death. Also stoke is s the number one cause of disability of the United States. The main reason why strokes occurs is hypertension, smoking, heart disease and family history. However 90% of the strokes is because of fat accumulated in the carotid artery or when the blood clots becoming to stay in the carotid arteries. There are six types of strokes these are ischemic stroke, transient ischemic attack (TIA), embolic stroke, hemorrhagic stroke, thrombotic stroke, and lacunar infarction

Ischemic Stroke is the death of the brain tissue that occurs because of lack of blood supply and insufficient oxygen to the brain due to blockage of an artery. During 60 to 90 seconds the brain tissue could stop working and after approximately three hours it will suffer irreversible injury possibly leading to death of the tissue. Most of the time that the Ischemic Stroke occurs is when the blood is clot or fatty deposit due to atherosclerosis.is blocking the

artery. The Diagnosis for the Ischemia Stroke is usually based on symptoms and results of a physical examination and brain imaging. Also other imaging tests like Computed tomography, Electrocardiography, and Echocardiography, in addition to this blood tests are also done to identify the type of the stroke the person is having... According to the American Heart Association 87 % of strokes that people have is Ischemia stroke and one third of people recover all or most of normal functions.
Most of the time symptoms occur suddenly and are often most severe a few minutes after they start because most ischemic strokes immediately begins, develop rapidly, and cause death of brain tissue within minutes to hours. The symptoms for the ischemia stroke are weakness of your muscle, paralysis, lost or abnormal sensation on one side of the body, difficulty speaking, confusion, problems with vision, dizziness, and loss of balance and coordination. Ischemia Stroke treatment may include drugs to break up blood clots or to make blood less likely to clot and procedures to physically remove blood clots, followed by rehabilitation. Preventive measures include control of risk factors, and sometimes surgery or angioplasty to open blocked arteries.
Transient Ischemia attack is a temporary episode of neurologic dysfunction cause by loss of blood flow. It is located in either focal brain, spinal cord or retinal without causing a death tissue. It is referred as mini stroke because it has the same underlying cause as strokes and interruption of cerebral flow blood. The main cause of TIA is an embolus that obstruct an artery in the brain. They symptoms for TIA are the same as Ischemia Stroke but with the difference that is not permanent and also is reversible. The treatment for TIA is also the same as Ischemia Stroke however to prevent a stroke its necessary to control high blood pressure, high cholesterol, and diabetes also avoid smocking. Eat healthy, and exercises regular and moderate weight. Taking an antiplatelet drug, such as aspirin a combination tablet of low-dose aspirin plus dipyridamole, reduces the chance that clots will form and cause TIAs.
The embolic stroke is a blood clots that forms in a part of the body but especially in the heart that travels through the bloodstream to the brain. When it gets there the clot immediately travel to a blood vessel that is small enough to block its passage. Embolic can also result from abnormal heartbeat which is a condition when the heart can’t beat effectively and the blood can pool and clot. Like ischemic stroke, the embolic stroke has the same symptoms. It is a life threatening condition in which every second counts. The treatment for embolic stroke depend in which area of the body happen the stroke. Clot busting drugs is use for the treatment so they can restore normal blood flow.
Hemorrhagic stroke happens 13% of the time.

It happens when a weak vessel breaks and bleeds into the brain which results blood to accumulate and compresses the brain. To help prevent hemorrhagic stroke patient should do brain imaging so they can evaluate and identify complications such as intraventicular hemorrhage, brain edema, or hydrocephalus. The symptoms for the hemorrhagic stroke are the same as the Ischemic stroke but also depends in which side of the body happen. The treatment depends on the cause and severity of the bleeding. Also medications are use for the treatment such as Anticonvulsant which help prevent seizure recurrence, antihypertensive agents help reduce blood pressure and other risk factors of heart disease and osmotic diuretics that helps decrease intracranial pressure in the subarachnoid

space.
Thrombotic stroke is the second type of blood clot stroke the blood flow is impaired because one or more arteries are block. This kind of stroke can also happen because of unhealthy blood vessels with fatty deposits and cholesterol. This type of stroke usually happens to older people especially those with high cholesterol. The symptoms of the thrombotic strokes can happen while you are sleep or early in the morning. Also it could happen over a period of hours or even days. To diagnosis this stroke it’s necessary to take two brain images like a CT scan and a MRI scan. To prevent a thrombotic patients should always check their high blood pressure so they can maintain the normal level also cholesterol, diabetes, and smoking.
All types of strokes are very dangerous because in just moment you can die and if you don’t die at the moment you can stay disabled for the rest of your life. That is a why it is important to maintain a healthy life, do exercises regulatory, have a good diet, but the most important be in constantly check with the doctor.
