Cerebrovascular accident (CVA) – also known as a stroke, occurs when the brain is damaged by the lack of blood flow, or can be caused by bleeding inside the head.…
A stroke, sometimes referred to as a cerebrovascular accident (CVA), 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.…
Cerebrovascular accident is well known as a stroke and affects around 800,000 people every year (Mclntosh, 2016). There are three types of strokes: ischemic, hemorrhagic and transient ischemic attacks (TIAs) (Mclntosh, 2016). Ischemic stroke is the most prevailing type of strokes with an 85 percent average rate (Mclntosh, 2016). It is cause by the reduction of blood flow, because of a narrowed or blocked artery in the brain (Mclntosh, 2016). Also, it is a rapid loss of blood supply which kill the cells of the brain and limits oxygen to go to that side of the brain (Mclntosh, 2016). For example, in the arteries that travels gets blocked because of a blood clots called thrombus (Mclntosh, 2016). Hemorrhagic stroke is the…
The most common type of stroke is ischemic, which refers to the loss of oxygen and nutrients for brain cells that occurs because the blood supply to a portion of the brain has been cut off. Ischemic strokes account for approximately 80% of all strokes, and can be further broken down into two subtypes: thrombotic, also called cerebral thrombosis, and embolic, also termed cerebral embolism.…
Stroke- where arteries that connect to the brain become blocked resulting in reduced blood flow, these blockages are usually caused by blood clots.…
Strokes are the third most common cause of death and in middle-aged or elderly people, it is the most frequent cause of a disability (Bledsoe, p.g.198). There are two broad categories of strokes, ischemic strokes and hemorrhagic strokes. Ischemic strokes are caused from a blockage in the artery which results in a lack of blood flow to the brain tissue. Hemorrhagic strokes are caused by a hemorrhage from a ruptured cerebral artery (Bledsoe, p.g. 198). An occlusive stroke, also known as an ischemic stroke is when a cerebral artery is occluded by a blood clot. The blockage results in ischemia (an inadequate amount of blood supply to the brain tissue) which results in infarction. The dead tissue will swell causing further damage to the surrounding tissues (Bledsoe, p.g.198). If the swelling is severe, it could lead to herniation which is the protrusion of brain tissue from the skull through the foramen magnum (Bledsoe, p.g.198). There are different types of ischemic strokes. An ischemic stroke that is caused from an embolus that was carried to the cerebral blood vessels from a remote site is also known as an embolic stoke (Bledsoe,…
Ischemic strokes are eventually caused by a thrombus or embolus that blocks blood flow to the brain. Blood clots (thrombus clots) typically happen in zones of the arteries that have been impaired by atherosclerosis from an accumulation of plaques. Embolus type blood clots are often instigated by atrial fibrillation i.e. an asymmetrical pattern of heart beat that result in blood clot formation and poor blood flow. Hemorrhage strokes can be caused by…
Annually, around 800,000 Americans have strokes when a blood blocks the circulation to the brain or when a blood vessel in the brain breaks. When this happens, brain cells are deprived of oxygen and die off. Additionally, memory, muscle control and other abilities controlled by that area of the brain are lost.…
There are three different kinds of stroke. One of the most common stroke is called Ischemic stroke. About eighty-five percent of strokes are ischemic strokes. It happens when the arteries to your brain become blocked, causing blood flow. The two common ischemic strokes are the Thrombotic stroke and Embolic stroke. When a blood clot forms in one of the arteries into your brain, the thrombotic stroke then occurs. It may caused by a fatty deposits that build up in the arteries and also reduces blood flow. An embolic stroke occurs when a blood clot forms away from your brain commonly in the heart. It is when embolus…
A stroke occurs when an artery bursts or becomes closed when a blood clot lodges in it and blood flow is interrupted to that part of the brain. Blood circulating to that area of the brain served by the artery stops at the point of rupture, and the brain tissue in that area dies or is damaged. The effects of a stroke are determined by which portion of the brain is affected and how much damage occurs. A stroke can cause memory loss, speech impairment, reasoning ability, loss of vision, paralysis, coma, and death, depending on what region of the brain is affected. Strokes are considered to be medical emergencies that require immediate treatment.…
Hemorrhagic is uncommon but usually results in death; this occurs when an aneurysm, a weakened blood vessel, in the brain bursts. Ischemic stroke is the more common form of stroke and occurs when there is a blood clot in one of the blood vessels leading to the brain (National Stroke Association, 2014). Strokes are an interesting topic to research because they are fairly frequently experienced. Due to how prevalent strokes are, it is helpful in terms of prevention, treatment, and rehabilitation to understand the neural bases of stroke and the brain structure after a stroke. Specifically the differences in brain structure after a stroke compared with brain structures before a stroke. Obviously with the lack of blood being able to get to the brain, there is going to be some damage to different brain structures, which can be seen in the symptoms after a stroke. This literature review will discuss how knowing the differences in structures after Traumatic brain injuries and strokes can help with the rehabilitation of the patients with…
Stroke is a is a medical emergency and can cause permanent neurological damage and death.Risk factors for stroke include old age, high blood pressure, previous stroke or transient ischemic attack (TIA), diabetes, high cholesterol, tobacco smoking and atrial fibrillation.1 High blood pressure is the most important modifiable risk factor of stroke.1 It is the second leading cause of death worldwide.2…
Most adults who have a stroke are between the ages of forty to eighty, but children can also have a stroke (Macrez, Ali, Toutirais, Le Mauff, Defer, Dirnagl, & Vivien 2011). A stroke occurs within the individual when the brain is not receiving enough oxygen or nutrients which slowly causes deterioration of the individual’s brain cell (Macrez, Ali, Toutirais, Le Mauff, Defer, Dirnagl, & Vivien 2011). There are three forms of strokes; ischemic, hemorrhagic, and TIA which is abbreviated for transient ischemic attack. An ischemic stroke is the most common out of the three. An ischemic stroke occurs when arteries are being blocked and this causes does not allow the brain to get enough blood. A hemorrhagic stroke happens when blood vessels began to weaken and cause bleeding which prevents oxygen from going to the brain as well as blood that it needs to function properly (Macrez, Ali, Toutirais, Le Mauff, Defer, Dirnagl, & Vivien…
An ischemic stroke is more common so I feel like medical professionals know how to treat/care for this best. Also, a hemorrhagic stroke is much more dangerous and more fatal. I would prefer it to be in the posterior part of my brain. The effects of this stroke maybe be loss of movement in your limbs, eye movement may be limited in one or both eyes, vertigo, etc. A posterior stroke has less negative side effects than a left-sided stroke, right-sided stroke, or a brainstem stroke. With a left-sided stroke, the effects are usually aphasia and language apraxia. With aphasia you may have problems with speaking, reading, writing, trouble thinking of the right words to say, etc. Language apraxia can make it difficult to speak exactly what you want to say or understanding the meaning of something. A right-sided stroke may take away your ability to focus, heat, touch, be aware of your own body, recognize people, visual issues, etc. A brainstem stroke is very serious and can cause heart problems, loss of hearing, numbness on one or both sides of your brain, trouble swallowing, or even coma. None of these areas for a stroke are ideal, but as you can see, a posterior stroke has the least amount of detrimental effects.…
The stroke patient is referred to acute physical therapy. Upon initial examination and evaluation of the patient, the physical therapist (PT) is responsible for determining the nature, status, and extent of the stroke. Based on the patient history, review of systems, and the results of the tests and measures of the examination, the PT makes a “clinical judgment” based on the collected data. A diagnosis and prognosis is established once consultation with other health professionals, such as a neurologist, is reviewed. A plan of care is designed and short- and long-term goals are outlined. Physical therapy goals may include performance in transitioning between sitting and standing, posture, balancing while standing and walking, and improved gait…
