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. 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 …show more content…
It is important that the type of stroke is diagnosed quickly to reduce the damage done to the brain and also to determine the right type of treatment because one treatment for one kind of stroke can be harmful to someone who has had a different kind. A number of different medications may be given at the hospital to help break up the clot and prevent the formation of new clots. For Ischemic stroke the treatment can begin with drugs to break down clots and prevent further ones from forming. Aspirin can be given, along with an injection of a tissue plasminogen activator (TPA). TPA works by dissolving clots but it needs to be injected within 4.5 hours of stroke symptoms once they have presented themselves. Hemorrhagic stroke treatment can begin with drugs being given to reduce the pressure in the brain, overall blood pressure, prevent seizures and prevent sudden constrictions of blood vessels.(http://www.mayoclinic.org/diseases-conditions/stroke/diagnosis-treatment/treatment/txc-20117296) Because strokes are life-changing events that can affect a person both physically and emotionally, temporarily or permanently. After a stroke,
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.
There are different types of stroke that a person can suffer from. One is called Ischemic Stroke, this happens when arteries that go to the brain become small or blocked. Common types of Ischemic stroke would be called Thrombotic stroke, when a blood clot is in one of the artery leading to the brain and the other is Embolic stroke, this is when a clot or debris are formed in the body and taken through the blood stream into a narrow
Medical experts emphasize that medical attention must be received within the first three hours of a stroke to repair blood flow and diminish damage.
Strokes are caused by a block in the blood supply to the brain which causes a decrease in oxygen and delivery of other important supplies which facilitate proper functioning. Fifteen million cases are reported worldwide annually, although not all of these cases are mortalities, the large prevalence of strokes ranks it as the fourth leading cause of death in the United States. (Figueroa) Because of the time sensitivity associated with the lack of resources to the brain, strokes are considered a medical emergency and early recognition of symptoms can help decrease the amount of damage caused . Although strokes do not always cause death, strokes most often leave the individual with some physical and cognitive impairment.
Stroke is the fourth leading cause of death in the United States. Each year more than 795,000 Americans suffer from a stroke, which means that every forty seconds someone has stroke (Liebman, 2012). Although a stroke can occur at any age, strokes are frequently seen in the older adult demographics. An increase with age doubles the risk for a stroke each decade after 55 (Grysiewicz, 2008). The percentage of stroke survivors to almost fully recover from a stroke is only 10 percent; in contrast, 40 percent of stroke survivors will face moderate to severe impairment which will entail distinctive care (Perlmutter and Colman, 2005). When all strokes are analyzed according to demography of class system, approximately 60% of strokes occur in low or middle income countries (Silverman and Rymer, 2009).
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.
Hemorrhagic stroke occurs when a blood vessels in the brain leaks or ruptures. Bleeding from the ruptured brain artery can either go into the substance of the brain or into the various spaces surrounding the brain. The two types of hemorrhagic stroke are Intracerebral and Subarachnoid hemorrhagic.
Stroke, or brain attack, is the number four killer of adults in the world. In the United States, 160,000 deaths occur each year. From 1999 to 2009, the death rate from stroke gradually lowered as improvements to medicine and testing developed. Yet, 800,000 Americans continue to have strokes and survive the event. Worldwide, about 15 million experience stroke with 6 million who die and 5 million who become permanently disabled. (Robinson, Richard & Odle, Teresa G. & Frey, Rebecca J. & Odle, Teresa G. , 2011) The statistics in America are better for surviving a stroke because of rapid response and better interpretation of symptoms. Nevertheless, surviving a stroke often brings on dilapidating effects; which means a change in lifestyle and lifelong rehabilitation through physical therapy.
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
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
In developed countries, stroke is relatively declining. With results to lower blood pressure and minimized smoking. However, the overall rate of stroke remains high due to the aging of the population. Stroke was the second-leading global cause of death behind heart disease, considering for 11.13% of total deaths worldwide based in 2010.
Each year alone about 150,000 people in America die from a stroke or are seriously disabled. Stroke is among the top five causes of death. It generally happens very suddenly and it can take up to five to seven days to completely effect the patient. Depending on how many of the brain cells die during the stroke, and
Approximately 795,000 people in the United States suffer from a stroke every year and almost 75% of those are first-time strokes. Strokes kill around 130,000 people a year, ranking it the number 5 cause of death in America. They are also the leading cause of long-term disability. Stokes can be defined as blood not being able to flow to the brain, and there are two ways this can happen, a clot and a rupture. When the blood clots, it is known as an Ischemic stroke, and around 87% of all strokes fall in this category. A rupture is known as a hemorrhagic stroke and is typically a result of an aneurysm or arteriovenous malformation of the brain ("Impact of stroke", 2016).
Stroke Stroke is characterized by poor blood flowto the brain resulting into death of the brain cells. This causes malfunctioning in parts of the brain. Types of Stroke 1. Ischemic stroke: Results from of lack of blood flow due to obstruction of blood vessels supplying blood to part of the brain. It’s the most rampant case of stroke accounting for 87% of the reported cases.
