    Besides cancer and heart diseases, stroke is the third leading reason behind death. Approximate 1/4 of all stroke victims die as the result of the stroke or it’s complications. Stroke is due to uncontrolled diet that is saturated in saturated and trans fats leading to cholesterol build-up in the arteries and raised blood pressure. Quite simply, if cholesterol accumulating in the arteries is blocking the circulation of blood in any portion of the body causing oxygen never to be delivered to the mind, resulting in some cells in the brain to die off and so are unable reproduce, then we have stroke. Other strokes happen whenever a blood vessel in the mind ruptures causing the cells in your brain to be deprived of oxygen in your blood, they die and never come back.

    I. Causes of Stroke

    There are similar causes of stroke and heart diseases, but in stroke the result is more severe. Any delay of rescuing will result in death of the victim. Here are some causes of stroke:

    1. Unhealthy diet

    A diet high in saturated and trans fats causes bad cholesterol to develop in your blood vessels in the brain, blocking oxygen necessary for the cells thus increasing the risk of stroke. Also unhealthy diet causes high blood pressure making your heart work harder to pump blood to your body in result of heart diseases. Raised blood pressure also causes the blood vessels in your brain to harden and thin, increasing the chance of stroke.

    2. Smoking

    Smoking not only includes a devastating effect on the fitness of the smoker but also to anyone who inhales its toxic fumes. Cigarettes contain high degrees of cadmium that causes the blood to clot activity of cells in result of blocking blood circulation and damaging the arteries in the brain.

    3. Excessive drinking

    Moderate drinking is wonderful for your heart, but excessive drinking can boost degrees of some fats in your blood causing cholesterol to develop in the arteries and blood vessels in the brain resulting in increase of the risk of stroke.

    4. Diabetes

    People with diabetes tend to develop cardiovascular disease or have strokes at a youthful age than other folks. Diabetes with unhealthy diet causes high blood sugar levels that damage nerves and blood vessels, leading to complications such as heart disease and stroke, the leading causes of death among people who have diabetes.

    5. Obesity – a body mass index of 30 or higher

    Study shows that even with adjusting for other stroke risk factors such as for example high blood pressure, diabetes, high cholesterol, smoking, cardiac diseases, moderate alcohol consumption, and exercise; obesity is still of a greatest risk of stroke in men and women.

    6. Use of contraceptive pills

    Birth control pills contain estrogen and something of two other hormones, lynestrenol or norethisterone that increase the risk of blood clotting, which can result in ischemic stroke especially in woman who smoke and that are older than 35.

    There are many other causes of stroke such as heart diseases that people have discussed lengthily in the heart diseases articles.

    II. Symptoms of Stroke

    Here are some outward indications of strokes:

    1. Sudden trouble in standing

    Sudden trouble in standing is an early symptom of stroke because of blood circulation that carries oxygen to suddenly deplete caused by narrowing of arteries and high blood pressure.

    2. Dizziness and loss of balance

    The brain coordinates information from the eyes, the inner ear, and your body’s sense to maintain balance. If the cells of that portion of the brain get damaged in result of depleted oxygen will cause dizziness and loss of balance.

    3. Sudden confusion

    A sudden onset of confusion means that something is potentially going wrong with the brain. Almost all conditions that affect the brain are life-threatening. It might be the effect of a tumor or low degrees of oxygen in the cells of the cerebral cortex in the human brain that affect your capability to think together with your usual speed or clarity. It might also be caused by lowered blood sugar, as may be the case of diabetes.

    4. Having trouble speaking and understanding

    Having difficulty speaking and understanding occurs when the brain cells in the area of the broca, wernicke and angular ayrus in the left hemisphere area commence to die because they stop obtaining the oxygen and nutrients they have to function.

    6. Sudden severe headaches

    Headache is a condition of pain in the head, sometimes neck or upper back pain can also be interpreted as a headache. It ranks between the most common local pain complaints and could be frequent for many people but sudden severe headaches may be caused by an early on symptom of heart disease as we mentioned in previous articles, by rupturing a brain vessel or depletion of oxygen in some parts of the brain.

    7. Sudden trouble seeing

    This may be an early on indication of stroke once the oxygen in the blood supply to the part of the brain is suddenly interrupted or whenever a blood vessel in the brain bursts, spilling blood into cells that control the vision section of the cerebral cortex in the brain.

    III. The Risk Factors

    1. Age

    Human aging may be the biological process that is unavoidable but controllable. Starting at age 40, the cells in our body begin this process evoking the deterioration of some functions of the body. Most people of this generation already have some form of cholesterol building up within their arteries and high blood pressure resulting in an increased threat of stroke.

    2. Heredity

    People with a family history of stroke have a larger potential for stroke than those don’t have such a family history.

    3. Race

    Because of frequent raised blood pressure in African Americans, they will have a significantly higher threat of stroke than their Caucasian counterparts.

    4. High blood pressure

    Raised blood pressure causes hardening and thinning of arterial walls and makes our heart work harder to pump blood throughout the body resulting in heart diseases and increasing the chance of stroke.

    5. Smoking

    Smokers may be exposed to toxic cadmium, causing raised blood pressure and heart diseases along with contributing to a higher risk of stroke.

    6. Excessive alcohol consumption

    Drinking one glass of wine for women and 2 cups of wine for men might help to increase the circulation of blood along with providing more oxygen for cells. However, excessive drinking not only damages the standard function of liver but additionally raises high blood pressure, increasing the chance of stroke.

    7. Diabetes

    Diabetes with unhealthy diet causes high levels of glucose in the bloodstream. Diabetics have a larger threat of stroke, because high degrees of glucose damage the arterial wall in addition to clotting the arteries and blood vessels.

    8. Gender

    Males have a 20% greater risk of stroke than females.

    IV. Types of Strokes

    There are 2 forms of strokes:

    1. Ischemic stroke caused by a clot or other blockage in a artery leading to the brain.

    2. Hemorrhagic stroke due to the vessel in the brain rupturing in result of blood leaking into the brain.

    1. Ischemic stroke

    This is the most typical type of stroke accounting for almost 80% of all strokes. The brain depends on its arteries to create fresh blood from the center and lungs. The blood carries oxygen and nutrients to the mind, and takes away carbon dioxide and cellular waste. If an artery is blocked then the brain cells may not receive enough oxygen. Then they cannot make enough energy and will eventually stop working.

    There are 2 forms of Ischemic stroke

    a)Thrombotic stroke.

    If blood clots from the inside of the arteries of the mind, we have thrombic stroke.

    Study shows that this kind of stroke is responsible for almost 50% of all strokes. The most typical problem is narrowing off the arteries in the neck or head. Thrombotic stroke are also sometimes known as large-artery strokes. The process resulting in thrombotic stroke is complex and occurs over time. Thrombotic stroke might be caused by the arterial walls slowly thickening and hardening due to arteries being injured. Such injures signal the disease fighting capability to release white blood cells to the site causing stroke. Thrombotic stroke also occurs when the inner wall of arteries were injured in result of less nitric oxide being produced, causing the hardening of the arteries. If the blood coagulum then blocks the already narrowed artery and shuts off oxygen to section of the brain, we have a thrombotic stroke.

    b) Embolic stroke

    If blood clotted in other parts of the body’s arteries subsequently entering the brain, we have embolic stroke. In this instance the clot was formed somewhere other than in the brain itself.

    The clot then travels the bloodstream until they become lodged and can not travel any more. This naturally restricts the blood circulation to the mind and results in embolic stroke. An embolic stroke occurs when a blood clot or other particle forms in a blood vessel away from your brain. It is almost always caused by a dislodged blood coagulum which has traveled through the arteries until it becomes wedged within an artery. It is also caused by irregular beating in the heart’s two upper chambers. This abnormal heart rhythm can cause poor blood flow and the formation of a blood clot.

    2. Hemorrhagic stroke

    Hemorrhagic stroke occurs when a blood vessel bursts in the brain, causing a rise of the fluid pressure on the brain and harms the mind by pressing it contrary to the skull. Hemorrhagic stroke is connected with high blood pressure, which stresses the arterial walls until they break.

    apakah penyakit stroke bisa sembuh total? There are 2 forms of hemorrhagic strokes:

    a) Intracerebral hemorrhage:

    Intracerebral hemorrhage is internal bleeding that may happen in any section of the brain. Blood may accumulate in the mind tissues itself, or in the area between your brain and the membranes covering it. Most commonly the problem arises in the small arterial inside the brain which were diseased causing these tiny arteries to start to leak. Because the actual source of the bleeding is frequently small, it can take time for the blood to develop resulting in outward indications of an intracerebral hemorrhage and often increases over minutes or hours. People might not notice the problems associated with bleeding into the brain and ischemic strokes.

    b) Subarachnoid hemorrhage

    Hemorrhagic strokes that cause bleeding into the fluid filled spaces located deep in the mind are called subarachnoid hemorrhage. Subarachnoid hemorrhage might occur at any age but is most common from age 40 to 65. It really is caused by the current presence of blood within the subarachnoid space from some pathological processes a result of ruptured aneurysms and bleeding may stop spontaneously. Other notable causes include vascular malformation, tumors and infection.The very best treatment is to proceed with microsurgical clipping of the lesion. This stroke causes paralysis of most limbs, unconsciousness and bleeding into the cerebellum produceing typical signs of in coordination with headache and stiffness of the neck.
