Stroke is a medical condition most people are familiar with, but most people are unaware of its effect on memory functions. There have been several studies conducted that study of effects of stroke on different memory systems, how to properly assess memory damage in stroke patients as well as how to improve memory after stroke. A major theme from the course that relates to stroke and memory is the theme of metamemory and its components such as prospective memory. Personally, I believe that these studies offer hope to stroke victims and their families because memory damage can evaluated and therefore a method of treatment can be developed.
Stroke is a serious medical condition that affects people of all ages specifically older adults. People suffer from a stroke when there is decreased blood flow to the brain. Blood supply decreases due to a blockage or a rupture of a blood vessel which then leads to brain tissues dying. The two types of stroke are ischemic stroke and hemorrhagic stroke. An ischemic stroke is caused by a blood clot blocking the artery that brings oxygenated blood to the brain. On the other hand, a hemorrhagic stroke is when an artery in the brain leaks or ruptures (“About Stroke,” 2013). According to the Centers for Disease Control and Prevention (CDC), “Stroke is the fourth leading cause of death in the United States and is a major cause of adult disability” (“About Stroke,” 2013). Stroke causes a number of disabilities and also leads to decreased mobility in over half of the victims that are 65 and older. The CDC lists several risk factors of stroke such as heredity, age, gender and ethnicity as well as medical conditions such as high blood pressure, high cholesterol, diabetes and excessive weight gain that in...

Traumatic brain injuries (TBI) account to a third (30.5%) of all injury-related deaths in the U.S. with an estimated 1.7 million individuals sustaining TBI each year (Center for Disease Control and Prevention, 2010). Classifications of brain injury (e.g., mild, moderate and severe) is mostly done using the Glasgow coma scale (GCS) which has gained broad acceptance for the assessment of the severity of brain damage (Bauer & Fritz, 2004). Recent studies suggest that almost all patients with moderate or severe TBI have a period of recovery during which they are responsive but confused. This state is commonly referred to as the post-traumatic amnesia. Post-traumatic amnesia (PTA) is defined as “a failure of continuous memory” (Artiola et al., 1980; p.377). PTA is often cited as the best method for codifying the degree, level of recovery and outcome after a closed head injury (e.g., Artieola et al., 1980; Tate, Pfaff, & Jurjevic, 2000). PTA duration is a better indicator of outcome than early injury scales such as the GCS score (Richardson et al., 2009).This analysis will examine the limitations of the general PTA assessment scale, and investigate the benefits and limitations of both retrospective and prospective methods used to measure the duration of PTA.
Globally the leading reason for mortality and morbidity rate is stroke. Nearly twenty million individuals can suffer from stroke annually and around five million individuals won't survive [1]. The developing countries account for a median of 85% of worldwide deaths from stroke [2]. Stroke ends up in practical impairments with a median rate of two hundredth survivors who need institutional care once an amount of three months and 15%-30% are going to be disabled for good [3].
A stroke can happen at any age but for patients who are 55 and older, their risk factor will increase due to age and physical activity. “While stroke is common among the elderly, a lot of people under 65 also have strokes”(“About Stroke” page 1). Also at risk are African Americans because of other health issues that can trigger a stroke, for example: high blood pressure, diabetes and obesity. Caucasians and Hispanics are also at. Not only does Ethnicity and age play a factor, but so does other health conditions. Patients who suffer from high blood pressure, diabetes, heart disease, obesity, alcohol and drug
It goes without saying that everyone’s health is important and should be taken care carefully. Everyone has heard of strokes before but many people do not really know its meaning, types, and the number of individuals of that dies due to this issue. According to Centers for Disease Control and Prevention (2015), strokes kills an average of 130,000 people a year and it is one of the most common deaths that happen in the United States. An average of 800,000 of people die from cardiovascular disease and strokes and it is also a reason of long-term disability (Centers of Disease Control and Prevention, 2015). Strokes, which can also be called cerebrovascular accident or CVA happen when the blood supply to the brain is interrupted or the blood vessel going towards the brain burst. Then part of the brain dies or become seriously injured because the brain cells do not receive oxygen and they eventually die. People’s lifestyle may also impact seriously on their health and increase the possibility of having a stroke. Some of the risk that can severely increase the cause of stroke would be high blood pressure, heart disease, diabetes, cigarette smoking, as well as strokes that

Cerebrovascular disease or the term stroke is used to describe the effects of an interruption of the blood supply to a localised area of the brain. It is characterized by rapid focal or global impairment of cerebral function lasting more than 24 hours or leading to death (Hatano, 1976). As such it is a clinically defined syndrome and should not be regarded as a single disease. Stroke affects 174-216 people per 10,000 population in the UK per year and accounts for 11% of all deaths in England and Wales (Mant et al, 2004). The risk of recurrent stroke within 5 years is between 30-43%. One problem is that the incidence of stroke rises steeply with age and the number of elderly people in the UK is on the increase. To date people who experience a stroke occupy around 20 per cent of all acute hospital beds and 25 per cent of long term beds (Stroke Association, 2004). The British Government now identifies stroke as a major economic burden on the National Health Service (DoH, 2002).
This condition is preceded by a decline in the baseline performance that is thought to be abnormal for the person’s age and abilities. Mild cognitive impairment is characterised by beginning of changes in memory as well as performance of daily. Severe cognitive impairment is compounded with the more serious loss of performance of the mental processes, resulting in that a person cannot live on their own (Fann et al, 2005). The health, social and economic impacts of cognitive impairments are clear to many health care providers. However, there has not been enough national attention given to this health concern.
Stroke is the third leading cause of death and the brain injuries caused by stroke are a huge cause of disability in older adults. There are over 1.2 million stroke survivors in the UK and half of all stroke survivors have a disability following their stroke. A person’s age increases their risk of having a stroke. Most strokes occur between the ages of 65 and 75. There are three main types of strokes. 85% of strokes are ischaemic and occur when a blood clot forms in an artery leading to the brain, stopping the blood supply causing a neurological defect lasting more than 24 hours (Alexander et al., 2011). 15% of strokes are haemorrhagic and result from a weakened blood vessel that has ruptured and bleeds into the surrounding brain. It can be
According to the American Heart Association / American Stroke Association’s About Stroke (2014) “stroke is the number four cause of death and the leading cause of adult disability in the United States” (para.1). On average, a stroke happens every 40 seconds in the United States (Impact of Stroke, para. 1) About 4% to 17% of all patients with stroke experience symptom onset while hospitalized (Cumbler, et al., 2014). This amounts to about 35,000-75,000 in-hospital strokes in the United States annually.
Stroke is one amongst the foremost distressing experiences that can happen to anyone. A stroke is caused by an intermission of the blood offer to half of the brain. The term ‘stroke’ comes from the actual fact that it always happens with none warning, ‘striking’ the person from out of the blue. Worldwide, each year 2/1000 individuals have a stroke. Five out of six strokes happen in individuals over the age of sixty. It is hardly ever obvious why somebody ought to have suffered a stroke. Contrary to widespread belief, stress, and either future or following a sudden event, is not in itself a reason behind a stroke. The most common is obtaining older and alternative factors are high blood pressure (hypertension), smoking, being overweight, having too much sugar in blood (diabetes) and having abundant in excessive amount of cholesterol in blood. Strokes occur once the blood flow within the brain is hampered and brain tissue is broken. There are 2 major varieties of strokes: Ischemic and Trauma. The severity of injury to the brain tissue depends on several factors together with age, area of the brain affected, and alternative medical conditions. If the hand and arm doesn’t have medical aid in real time when stroke, it will reduce the power and muscle management, leading to a claw like look and loss of perform. Activities of the patient daily legal document will be significantly affected.
The World Health Organisation (2013) explains that an Ischaemic stroke occurs as a result of a blood vessel becoming blocked by a clot, reducing the supply of oxygen to the brain and, therefore, damaging tissue. The rationale for selecting Mary for this discussion is; the author wishes to expand her evidenced based knowledge of stroke since it is the principal cause of disability and the third leading cause of mortality within the Scottish population (Scottish Intercollegiate Guidelines Network (SIGN), 2008) and, therefore, a national priority. In response to this priority, the Scottish Government (2009) produced their ‘Better Heart Disease and Stroke Care Action Plan’. Additionally, they have introduced a HEAT target to ensure 90% of stroke patients get transferred to a specialised stroke unit on the day of admission to hospital (Scottish Government, 2012).
Stroke occurs when the blood supply to the brain is blocked or condensed. Blood works to transport oxygen and other beneficial substances to the body’s cells and organs, as well as the brain. There are two main types of strokes that are known as Ischemic strokes and Hemorrhagic strokes. When the blood vessels that provides for the brain becomes congested, is it referred to as ischemic stroke, the most common stroke within adults. Blood clots, a cluster of blood that sticks together, are the cause of Ischemic strokes. Ischemic strokes also takes place when arteries become backed up with plague, leaving less blood to flow. Plague is cholesterol, calcium and fibrous and connective tissue that sticks to the walls of blood vessels. Ischemic strokes eternally damage the brain and cause a person's body to no longer function habitually.Some risk factors that may increase stroke are high cholesterol, diabetes, high blood pressure, and obesity. Some stroke factors are also due to old age or having a family that has a history of strokes. Men are more likely to have a stroke but the most st...
Stroke is a commonly known disease that is often fatal. This cellular disease occurs when blood flow to the brain is interrupted by either a blood clot halting the progress of blood cells in an artery, called an Ischemic stroke, or a blood vessel in the brain bursting or leaking causing internal bleeding in the brain, called a hemorrhagic stroke. When this happens, brain cells are deprived of oxygen and nutrients because the blood cells carrying these essential things are stopped, causing them to die. When the cells in the brain die, sensation or movement in a limb might be cut off and may limit an organism’s abilities. A person with stroke is affected depending on where in the brain the stroke occurs. In other words, symptoms of a stroke

Historically, memory has been a recurring topic in cognition research. Through the years, many scientific findings have helped us to understand how memory works. Since, older adults are the subgroup most affected by frequent memory deficiencies, they would be highly benefited with the advance of the cognitive
