Causes And Symptoms Of Cerebrovascular Accident

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.

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

* Cerebrovascular Disease: More commonly known as stroke cerebrovascular disease can be cause by either a colt or blockage that cuts off blood flow to a part of the brain or by haemorrhage. In both cases there is damage or death of the brain tissue that can cause paralysis, speech disorder, swallowing problems and immobility. People with diabetes and high blood pressure are at higher risk of stroke.

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).

Cerebral vascular accidents are also known as strokes. Strokes can cause minimal to severe brain damage which can affect a person’s quality of life. This paper covers the definition, signs and symptoms, treatments, causes, prevention and what a nursing assistant can do to help someone recovering from a stroke.

The diagnostic process for a formally diagnosing Cerebral Vascular Accident (CVA/stroke), would consist with a number of test including a physical exam and questions regarding your family history of strokes, any signs or symptoms that may have been present before the patient had the stroke. The physician would also order a few tests like a MRI, CT scan, Cerebral Carotid ultrasound, Cerebral Angiogram and an Echo Cardiogram. The physical exam is important to listen to the hearts sounds, take your blood pressure and also use a ophthalmoscope ( a scope to look in your eyes, ears and nose) to see if there are any cholesterol crystals behind the eyes("Diagnosis - Stroke - Mayo Clinic," 2015). A MRI, uses radio and magnetic waves to show a detailed

Cerebrovascular Accident- condition in which brain tissue is deprived of blood supply.  The most common stroke symptoms are:

Hemorrhagic stroke is, the less common types of CVA, nearly 13% is all stroke cases and is a result from bleeding into the brain tissue itself (Intracerebral and intraparenchymal hemorrhage) or into subarachnoid space or the ventricles (subarachnoid hemorrhage or intraventricular hemorrhage). This type of stroke is further subdivided into:

Marsha is a single mother of three, the youngest being in high school. She works as a sales associate in the women’s fashion section of a larger department store. Last year, Marsha experienced a cerebral vascular accident, or stroke, while on her way to work and was brought in to the hospital. Strokes occur when the blood supply of the brain is disrupted, such as an ischemic attack, thrombosis, or a ruptured blood vessel. When the patient awoke in the hospital, she was unable to understand the staff or her family and expressed difficulty in forming replies. This suggests that the CVA may have occurred in the left hemisphere of the brain, specifically in the Broca and Wernicke’s areas. The medical team suggested that Marsha be released from

Stroke previously known as Cerebrovascular accident is well-defined as ‘an abrupt cessation of cerebral circulation in one or more of the blood vessels distributing the brain. Due to the interruption or diminish of oxygen supply causes serious damage or necrosis in the brain tissues (Jauch, Kissella & Stettler, 2005). There is a presence of one or more symptoms such as weakness or numbness or paralysis of the face, arm or leg, difficulty speaking or swallowing, dizziness, loss of balance, loss of vision, sudden blurring or decreased vision in one or both eyes and headache. Stoke is categorised into two types, Ischaemic and haemorrhagic

My clinical tenure at Taylor Hospital exposed me to patients with a variety of afflictions, among them was a patient post CVA (cerebrovascular accident), I worked with this patient for four weeks. Stroke, also known as cerebrovascular accident (CVA), cerebrovascular insult (CVI), or brain attack, is when poor blood flow to the brain results in cell death, CVA’s are classified as ischemic or hemorrhagic strokes (Stroke, 2015). RB is a 56 year old African-American female with a past medical history of previous CVA, hypertension, diabetes, dyslipidemia. RB presented at Taylor Hospital’s emergency room with a chief complaint of right sided weakness. A CAT scan of her head revealed an acute left frontal lobe infarct, an MRI revealed a subacute

Each year, around 800,000 people have a new or recurrent stroke. The characteristics include face drooping or feeling numb, difficulties speaking, and muscle weakness on one side of the body. Stroke is caused from reduced or interrupted blood supply to the brain. There are ischemic strokes (thrombic and embolic strokes), hemorrhagic strokes (intracerebral hemorrage and subarachnoid hemorrhage), and transient ischemic attack (TIA).

A cerebrovascular accident more commonly known as a stroke or brain attack is the term used to describe the sudden death of brain cells in a localized area due to inadequate blood flow. In order to woke the brain needs a constant supply of oxygen and nutrients. This supply is carried to the brain

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

A stroke also known as cardiovascular accident (CVA) is a serious killer and cause of disability. It occurs when a blood vessel breaks causing an interruption of blood flow to the brain or a blood clot blocks arteries leading to brain cells beginning to die and brain damage. This process can be caused by thrombosis hemorrhage or embolism, resulting in either left side or right side hemiplegia. Strokes only effect one side of the brain (Carter, & Van Andel 2011). There are three pathological types of strokes primary intraccerebral hemorrhage, ischaemic stroke, and subarachnoid hemorrhage (Warlo, Martin, Wardlaw, & Sandercock, 2003). While dealing with a stroke their can also be a transient ischaemic attack (TIA) also know as a mini stroke. This occurs when the blood supply to the brain is blocked for a short period of time. Transient ischaemic attack acts more like a warning sign there is temporary brain malfunctions but with continued occurrence it could cause dementia (Staessen & Wang, 2001). Strokes may lead to problems with awareness, thinking, attention, learning and memory. Other problems that may occur are difficultly controlling their emotions or show inappropriate emotions which lead to a high rate of depression in stroke patients (National Institute of Neurological Disorders and Stroke, 2014). Evidence shows that after a stroke depression and anxiety are prevalent and often long-term for survivors, continuing up to five years after an incidence of stroke (Murray et
