Stroke is one of the largest causes for the death. It is a medical emergency and it should be treated immediately. The blockage or rupture of an artery to the brain disrupts the blood flow to the brain. As a result, the oxygen and nutrient cannot be delivered to the brain and causes the death to brain cells. The brain function becomes abnormal which leads to stroke. A stroke can be referred as Cerebrovascular accident also.

Causes:

Proper and quick diagnosis is the most important factor in the treatment of any disease. Unless you correctly diagnose the disease, you can't give the adequate treatment. The stroke is one of the serious problems resulted from the inadequate blood supply to the brain. It can lead to permanent damage to the brain cells and some disabilities. Generally, the disabilities caused due to the stroke are permanent. They completely change the lifestyle of the stroke victim. Hence, it is very essential to consider the stroke as medical emergency and treat it immediately.

The stroke is a condition of body caused due to interrupted or severely reduced blood supply to the part of brain. Due to this condition, the brain tissues don't get sufficient amount of oxygen and nutrients. As a result, the brain cells start to die. It causes damage to brain and potential disability. Knowing signs of stroke makes it possible to get the proper treatment.

A stroke occurs when the blood supply to a part of the brain suddenly stops or is interrupted. The brain cells don't receive oxygen and nutrients that blood supplies with it hence they are damaged or dead. Effects of the stroke depend upon the severity and damage happened. So it is better to prevent such disease. What causes the stroke is the thing we must know to avoid the stroke. Normally stroke triggers are surprisingly routine things like drinking alcohol, lifting a large box. High blood pressure is a huge risk factor for stroke in people who have had previous stroke. High blood pressure and high cholesterol are the risk factors. Researchers have interviewed the people who had strokes, what they had done in 24 hours before stroke. They found that

The stroke is a very serious condition and should be taken as the medical emergency. If the prompt treatment is not taken, it can cause permanent damage of brain tissue and even causes death. For the proper treatment, the quick and accurate diagnosis is very essential. There are different methods of diagnosis of stroke such as MRI scan, CT scan, electroencephalogram, Doppler ultrasound test and carotid phonoangiography.

When you experience a stroke, you should immediately seek the doctor to get the proper treatment and prevent it from becoming worse. When you visit the doctor, he will start by giving a physical examination so that he can find out what type of stroke you have faced. This physical examination of the stroke includes the following processes:

A stroke can cause some serious consequences. These consequences may not be only physical as a stroke also alters the way of thinking of the victim. One of the most serious consequences of a stroke is language disability. More commonly called "Aphasia" in the medical community, linguistic disability is caused due the lack of supply of blood or the stoppage of blood supply to the left part of the brain. This is because the left part of the brain is responsible for the languages.

Cholesterol is a fat which is basically found in the animal cells. Our bodies also produce it and they are also absorbed from the food products of animals that we consume such as dairy products, meat, mutton, etc. high levels of cholesterol in the blood results in building up of fats in the arteries that carries the blood through the body. Such a built up of fat causes narrowing or blocking of the arteries. This stops the flow of the blood or the formation of blood clots in the narrowing areas. Having a diet that is too high in saturated fats is the main reason for causing high cholesterols.

A stroke occurs when the blood supply to a part of the brain suddenly stops or is interrupted. The brain cells don't receive oxygen and nutrients that blood supplies with it hence they are damaged or dead. A stroke is known as 'cerebrovascular accident'. Severity of the stroke varies depending on the conditions where it occurred and the extent of the damage. Sometimes it may give unconsciousness or death also. On the contrarily a small stroke may not even be noticed as their duration and symptoms are minimum.

Stroke education means everybody should have knowledge of symptoms, causes and the methods to prevent it and avoid it.

When brain cells are damaged or dead because of lack of oxygen and nutrients, it is called stroke. Stroke can be of two types Ishchemic stroke and Hemorrhagic stroke.. There are two main causes of stroke. The stroke caused by a blockage from narrowing of the arteries or clot in the blood vessel supplying the brain, is called as Ischemic stroke.

Hemorrhagic stroke is due to bleeding into or around brain.

Symptoms of stroke are sudden numbness or weakness of the face, arm or leg, sudden confusion, trouble speaking or understanding speech, sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, loss of balance or coordination and sudden headache with no reason. The symptoms also depend on the type of stroke and the area of the brain affected.

Symptoms like muscle weakness, numbness, reduction in sensory or vibratory sensation are caused when the area of the brain affected contains the central nervous system path systems -the spinothalamic tract, corticospinal tract and dorsal column.

Stroke and coma are considered as the 2 extreme risks of diabetes. Coma is the state of unconsciousness of the body as well as the mind for unknown length of time. He is not at all aware of his surrounding and what is happening around him. He is unable to respond or sense the environment. It is such a state of the body that there is no hope of recovery. There are different causes for coma: diabetes, stroke, infections or brain tumor.

The connection of migraine and stroke is a double bind for the neurologists. Migraine is closely connected with a greater risk of stroke and it is one of the independent risk factors for causing an ischemic stroke in individuals. T6he exact origin of the disease is yet not known but studies report that there is some mechanism related between the two diseases. Migraine related strokes can be classified in three main categories:

1. stroke with clinical features of migraine

2. co-existing stroke and migraine

3. migraine induced stroke

The stroke is a sudden interruption or reduction in the blood supply to the brain. The most common reasons of stroke are the blockage of the arteries leading to the brain, bleeding into the brain tissue due to bursting of the blood vessel. The stroke is also called as the brain attack. There are several types of stroke caused due to various reasons.

The two main types of stroke are the ischemic stroke and the hemorrhagic stroke. The ischemic stroke is caused due to too little blood in the brain, while the hemorrhagic stroke results from too much blood within the skull.

The most important part of recovering from a stroke is rehabilitation. It helps you to relearn your basic skills like speaking, dressing, walking and eating. Rehabilitation helps to improve the function of a person and make them as independent as possible. The rehabilitation process depends on the type and effect of the stroke that includes a rehabilitation hospital, a rehabilitation unit in the hospital, home therapy, home with outpatient therapy and a long-term care facility that provides therapy and skilled nursing care. The rehabilitation should be started within two days after the stroke has occurred specially with medically stable patients and continued even after leaving the hospital. It can take months or years to improve the condition in some cases it might worsen.

Electrocardiogram

The purpose of this technique is to detect ischemia or acute coronary injury in broad. It is a symptomatic emergency. However this technique has several limitations. An ECG represents brief sample of time because the syndromes are changing quickly, so from ECG it is not possible to track full symptoms of heart stroke, Therefore it is necessary to obtain ECGs particularly if the first ECG is obtaining while patient is pain free (chest pain). There are several emergency departments and chest pain centers are capable of monitors ST segment continuously.

Angiography

The more long the stroke goes without intervention; there are more chances of the brain to get injured. Its treatment on the proper time is very important. You should not waste time in waiting for the symptoms to go away. The interventions which can help in the prevention of the ischemic stroke in individuals having warning signs include blood-thinning medicines like the Warfarin and the aspirin. It also includes surgical procedures such as the carotid Endarterectomy i.e. removal of the narrow part of the artery and angioplasty i.e. stenting.

Stroke Specific Interventions:

The secondary prevention of stroke involves identifying and treating the people with the established disease and the people with the high risk of developing the disease. They are identified through screening. The major risk factors for stroke are hypertension, diabetes and heart disease.

The high blood pressure is the most common cause of ischemic stroke. Hence, it is very essential to control the blood pressure if you already have the hypertension. Lowering blood pressure can prevent the ischemic stroke. Excessive body weight, stress and alcohol intake are the main causes of high blood pressure. It can be kept under control by maintaining a healthy weight, exercising, limited alcohol intake, managing stress and limiting the sodium intake. Along with these preventive measures, it is necessary to take the medications such as angiotensin receptor blockers, diuretics and angiotensin-converting enzymes recommended by the physician.

It has been found that studies indicate cigarette smoking as one of the important risk factors for causing the stroke. Cigarettes contain nicotine and carbon monoxide smoke that damages the cardiovascular system of the body in a number of ways. Inhaling the smoke of the cigarette produce certain effects, thus damaging the cerebrovascular system. Women thaose who are taking oral contraceptives and smoke at the same time are prone to increase their risk towards strokes.

The two types of strokes are the Ischemic stroke occurs due to blockage of a blood vessel; the other hemorrhagic stroke is caused by bleeding. Bleeding strokes have a much higher fatality rate than strokes caused by clots.

When an artery to the brain is blocked ischemic stroke occurs. The arteries bring flesh blood from the heart and lungs and supply the brain. Carbon dioxide and cellular waste are removed from the blood and carries oxygen and nutrients to the brain. When this artery is blocked the brain cells cannot make enough energy and finally stops working and the brain cells will die if the artery is blocked for more than a minute. Here immediate medical attention is absolutely critical.
