A stroke or cerebrovascular accident (CVA) occurs when the blood supply to a part of the brain is suddenly interrupted. In brain tissue, a reduction of blood flow, ischemia, leads to an ischemic cascade that can damage or kill brain cells. Death of brain tissue can lead to loss of the function controlled by that tissue. Thus stroke is the third leading cause of death and leading cause of adult disability in the US and industrialized European nations (Jauch, 2005), and is a medical emergency. To underscore the seriousness ...

The two-stroke cycle of an internal combustion engine differs from the more common four-stroke cycle by having only two strokes (linear movements of the piston) instead of four, although the same four operations (intake, compression, power, exhaust) still occur. Thus, there is a power stroke per piston for every engine revolution, instead of every second revolution. Two stroke engines can be arranged to start and run in either direction. Two-stroke engines are used most among the smallest and largest reciprocating ...

The butterfly, (fly for short) is a swimming stroke swum on the breast, with the arms moving synchronously. The butterfly kick was developed separately, and is also known as the dolphin. While other styles like breaststroke, front crawl, or backstroke can be swum easily even for beginners, the butterfly requires a very good technique to be feasible. Most students consider it the most difficult style. It is also the newest swimming style swum on competitions, first swum around 1934. Butterfly stroke - Speed ...

Apoplexy is an old-fashioned medical term, generally used interchangeably with cerebrovascular accident (CVA or stroke) but having other meanings as well. Apoplexy - Stroke. The use of apoplexy for the term stroke is derived from the fact that many patients lose consciousness during the acute stage of the vascular compromise (either through bleeding or ischemia). It is not to be confused with cataplexy (an attack of the neurological syndrome narcolepsy). Occasionally, the term ' ...

Car engines are needed to make the vehicle run. Most car engines these days work by four-stroke internal combustion system. The reason for this is that there are four main stages in converting the fuel in the engine into a force that can move the car. The four stroke cycle is also referred to sometimes as the Otto cycle, named after the man (Nikolaus Otto) who invented it in 1867. This cycle occurs in each cylinder of the engine.

Migraine headaches are usually characterized by severe pain on one or both sides of the head, an upset stomach, and at times disturbed vision.

A canoe is a relatively small boat, typically human-powered, but also commonly sailed. Canoes are pointed at both ends and usually open on top. In its human-powered form, the canoe is propelled by the use of paddles, with the number of paddlers depending on the size of canoe. Paddlers face in the direction of travel, either seated on supports in the hull, or kneeling directly upon the hull. In this way paddling a canoe can be contrasted with rowing, where the rowers face away from the direction of travel. Pa ...

The most important risk factors for stroke are hypertension, heart disease, diabetes, and cigarette smoking. Other risks include heavy alcohol consumption, high blood cholesterol levels, illicit drug use, and genetic or congenital conditions. Family members may have a genetic tendency for stroke or share a lifestyle that contributes to stroke. Having had a stroke in the past greatly increases one's risk of future strokes. One of the most significant stroke risk factors is advanced age. 95% of strokes occur in people age 45 and older ( ...

Prevention is an important public health concern. Identification of patients with treatable risk factors for stroke is paramount. Treatment of risk factors in patients who have already had strokes (secondary prevention) is also very important as they are at high risk of subsequent events compared with those who have never had a stroke. Medication or drug therapy is the most common method of stroke prevention. Aspirin (usually at a low dose of 75 mg) is recommended for the primary and secondary prevention of stroke, and treating hypertension is another way to mo ...

Stroke - Ischemic stroke. Ischemic stroke is usually caused by atherosclerosis (fatty lumps in the artery wall), embolism (obstruction of blood vessels by blood clots from elsewhere in the body), or microangiopathy (small artery disease, the occlusion of small cerebral vessels). Atrial fibrillation and other arrhythmias can lead to clot formation in the heart, which can become emboli and lodge in the brain. Some forms of thrombophilia (increased coagulation tendency) have a predilection for arterial thrombosis and stroke; these include polycythemia vera and the rare par ...

Prevention is an important public health concern. Identification of patients with treatable risk factors for stroke is paramount. Treatment of risk factors in patients who have already had strokes (secondary prevention) is also very important as they are at high risk of subsequent events compared with those who have never had a stroke. Medication or drug therapy is the most common method of stroke prevention. Surgery such as Carotid endarterectomy can be used to remove significant narrowing of the neck (internal) carotid artery which supplies blood to the brain. This operation has been shown to be an effective way to prevent str ...

Stroke - Early assessment. It is important to identify a stroke as early as possible because patients who are treated earlier are more likely to survive and have better recoveries. If a patient is suspected of having a stroke, emergency services should be contacted immediately. The patient should be transported to the nearest hospital that can provide a rapid evaluation and treatment with the latest available therapies targeted to the type of stroke. The faster these therapies are started for hemorrhagic a ...

Disability affects 75% of stroke survivors enough to decrease their employability (Coffey et al., 2000 p.601). Stroke can affect patients physically, mentally, emotionally, or a combination of the three. The results of stroke vary widely depending on size and location of the lesion (Stanford, 2005). Dysfunctions correspond to areas in the brain that have been damaged. Some of the physical disabilities that can result from stroke include paralysis, numbness, pressure sores, pneumonia, incontinence, apraxia (inability to perform learned ...

Over 2,400 years ago, Hippocrates (460 to 370 BC) was first to describe the phenomenon of sudden paralysis, which we now know is caused by stroke. Apoplexy, from the Greek word meaning "struck down with violence,” first appeared in Hippocratic writings to describe stroke symptoms (Kopito 2001; Thompson 1996). In 1658, in his Apoplexia, Johann Jacob Wepfer (1620-1695) identified the cause of hemorrhagic stroke when he suggested that people who had died of apoplexy had bleeding in their brains (NINDS 1999; Thompson 1996). Wepfe ...

Stroke is diagnosed through several techniques: a neurological examination, blood tests, CT scans (without contrast enhancements) or MRI scans, Doppler ultrasound, and arteriography. If a stroke is confirmed on imaging, various other studies may be performed to determine whether there is a peripheral source of emboli: an ultrasound/doppler study of the carotid arteries (to detect carotid stenosis) an electrocardiogram (ECG) and echocardiogram (to identify arrhythmias and resultant clots in the heart which may spr ...

The symptoms of stroke include the following: sudden numbness or weakness, especially on one side of the body (hemiplegia); reflexes can initially be decreased on the affected side, but are often more exaggerated than on the unaffected side; the face is normally spared (as this is served by both hemispheres), but the corner of the mouth can be affected on the same side as the limb symptoms; sudden confusion or aphasia (trouble speaking) or understanding speech; sudden trouble seein ...
