Stroke is a cerebrovascular accident with sudden onset of focal neurological deficits(s) from either infarction or hemorrhage within the brain.
• Ischemic stroke (thrombotic or embolic); 87%
• Hemorrhagic stroke (intracerebral or subarachnoid); 13%

Risk factors

• Age: >45 years; highest during the 7th and 8th decades
• Male > Female (3:1), equalizes after menopause
• Family history/genetics
• Prior stroke or TIA
• Smoking, heavy alcohol use, substance abuse (cocaine, amphetamines)
• Diabetes mellitus, obesity, metabolic syndrome, impaired glucose tolerance
Hypertension, atrial fibrillation, valvular heart disease, severe carotid artery stenosis
• Hypercoagulable states (including use of OCP), pregnancy and postpartum states

Etiology

…show more content…
• Hemorrhagic stroke: Hypertension, intracranial aneurysms, cerebral amyloid angiopathy, secondary hemorrhage into previous infarcts.

Diagnosis:

I. History:
Acute onset of focal arm/leg weakness, facial weakness, difficulty with speech or swallowing, vertigo, visual disturbances, diminished consciousness; presence of vomiting and severe headache favor diagnosis of hemorrhagic stroke
II. Physical Exam
• Anterior (carotid) circulation: Hemiparesis/hemiplegia, neglect, aphasia, visual field defects
• Posterior (vertebrobasilar) circulation: Diplopia, vertigo, ataxia, facial paresis, Horner syndrome, dysphagia, dysarthria

III.Tests

    The leading cause of long term disability in the United States is stroke, and one American dies from stroke about every four minutes. Stroke by definition is the sudden death of brain cells due to lack of oxygen. The main types of stoke are hemorrhagic, ischemic, and a transient ischemic attack. Hemorrhagic stroke is broken in to two types, and the most common is the intracerebral hemorrhage, when an artery in the brain bursts flooding the brain with blood. The second and less common subarachnoid hemorrhage, when bleeding occurs in the area between the brain and the thin tissue that covers it.…

    "Brain injury referred to as traumatic brain injury (TBI), is defined as an alteration in brain function or other evidence of brain pathology caused by an external force. Acquired brain injury (ABI), is defined as an injury to the brain which is not hereditary, congenital, degenerative or induced by birth trauma. Today, any traumatic brain injury is an acquired brain injury, defined as any acquired disruption of brain function. " Causes of TBI are trauma (open, closed, crushed, penetration: gunshot or knife wound, severe shaking or from contact sports), stroke (bleeding or a blocked artery), Anoxia (absence of oxygen), severe infection (meningitis, encephalitis), tumor (compression on the tissues causing malfunction), surgery (the actual cutting into a brain to remove a tumor or piece of the brain).…

    Strokes are the third leading cause of death in the U.S., accounting for 140,000 deaths each year in the U.S., and over 5 million worldwide. They are caused by blood clots or vessel ruptures in the brain, causing the death of the surrounding brain cells. There are two types of strokes: ischemic strokes and hemorrhagic strokes. Ischemic strokes are caused by blot clots that form in the brain, called thrombotic strokes, or form in other body parts and travel to the brain, called embolic strokes. This type of stroke accounts for 87% of all stroke cases.…

    I was assigned into a group of 3 people to work on a case study on an elderly patient who showed-up into the ER who had an ischemic stroke that is caused by an occlusion of a cerebral artery. During this group case study, I have learned so much about the critical care of older adult, such as the relationship of stroke and cardiovascular diseases (a-fib), complications of stroke, and the nursing critical implications of caring for older adult who suffers from cerebrovascular events. Upon assessment of the case, and based on the presenting signs and symptoms of the patient when she came into the ER, N.T a 79-year, complained of mild headache over the right side of the head, was fatigued, and slightly exhausted, and lacking-of physical strength and energy (case study hand-out). Physiologically and diagnostically it is evidently that patients with lesions in the right hemisphere often show signs of left unilateral neglect, a disabling impairment in orienting and responding to events occurring on the left side of space. Furthermore, upon…

    Stroke is linked to several other chronic diseases such as diabetes, hypertension, obesity, hyperlipidemia, and heart failure. Of these disease processes four of them are more common among African Americans. According to Feng (2015) the incidence of stroke has been declining in recent years however, in the southeastern states the occurrence of stroke is increasing. This has been shown to be especially true among middle-aged African Americans. Despite years of work aimed at lowering the rate of stroke more recent data has shown that while hospitalization due to stroke among whites is not increasing the incidence of stroke among middle aged black population in such states as South Carolina is increasing.…

    The most common causation theory is hypertension. Hypertension is the simply the stressing of blood flow to the heart and the brain. When hypertension occurs, it can and will most likely result in a fatty substance buildup in a blood vessel away from the brain (embolic ischemic stroke) thus causing an ischemic stroke. In addition to the previous causation theory, I believe the conflict theory is also a sociological theory associated with stroke.…

    Transient ischemic attacks are often referred to as “mini strokes” which may be a warning sign for a much more severe attack that can lead to a stroke (National Stroke Association 2014). Risk Factors Individuals that are at risk for TIAs are those who have hypertension, cardiac disease (atrial fibrillation, myocardial infarction, and Valvular disease), diabetes, hyperlipidemia, atherosclerotic disease, cigarette smoking and thrombophilia (Domino, Golding, & Grimes, 2014).

    This case study was performed remembering the ultimate objective to support and appreciate the unmistakable characteristics of CVA and its signs and symptoms. The focus of this case study will be on hemorrhagic strokes. A cerebrovascular accident (CVA) or stroke is caused by an acute lack of blood supply to part of the cerebrum. There are two major types of stroke: ischemic, in which a blockage (a blood clot) diminishes or ends blood stream, and hemorrhagic, in which bleeding in the brain triggers a reaction that limits blood supply somewhere else.…

    Hemorrhagic stroke can be categorized into intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). Intracerebral hemorrhage happened when blood vessel than within the brain gets hurt and leaks blood into the surrounding brain tissue and thus puts pressure on the surrounding tissue. Some common causes of intracerebral hemorrhage include high blood pressure, accidental injury, bleeding disorders and deformities in blood…
