Stroke - Causes, Symptoms, the Risk Factors, Types, Prevention and Treatment

Besides cancer and heart diseases, stroke is the third leading reason behind death. Approximate 1/4 of all stroke victims die as a direct result of the stroke or it's complications. Stroke is caused by uncontrolled diet that is saturated in saturated and trans fats resulting in cholesterol build up in the arteries and raised blood pressure. In other words, if cholesterol building up in the arteries is blocking the blood circulation in any section of the body causing oxygen never to be delivered to the mind, leading to some cells in the brain to die off and so are unable reproduce, then we've stroke. Other strokes happen when a blood vessel in the mind ruptures evoking the cells in the human brain to be deprived of oxygen in your blood, they die rather than come back.

I. Causes of Stroke

There are similar factors behind 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 several causes of stroke:

1. Unhealthy diet
A diet high in saturated and trans fats causes bad cholesterol to build up in your blood vessels in the brain, blocking oxygen needed for the cells thus increasing the chance of stroke. Also unhealthy diet causes high blood pressure making your heart work harder to pump blood to your system in result of heart diseases. High blood pressure also causes the arteries in your brain to harden and thin, increasing the chance of stroke.

2. Smoking
Smoking not only has a devastating effect on the fitness of the smoker but additionally to anyone that inhales its toxic fumes. Cigarettes contain high degrees of cadmium that causes the blood to clot activity of cells in consequence of blocking blood flow and damaging the blood vessels 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 build up in the arteries and blood vessels in the brain leading to increase of the chance of stroke.

4. Diabetes
People with diabetes have a tendency 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 more
Study shows that even after adjusting for other stroke risk factors such as high blood pressure, diabetes, raised chlesterol, smoking, cardiac diseases, moderate alcohol consumption, and physical activity; obesity is still associated with a greatest risk of stroke in people.

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, that may result in ischemic stroke especially in woman who smoke and that are older than 35.

There are many other causes of stroke such as for example heart diseases that we have discussed lengthily in the center diseases articles.

II. Symptoms of Stroke

Here are some symptoms of strokes:

1. Sudden trouble in standing
Sudden trouble in standing is an early symptom of stroke as a result of circulation of blood that carries oxygen to suddenly deplete due to narrowing of arteries and high blood pressure.

2. Dizziness and loss of balance
The mind coordinates information from the eyes, the inner ear, and the body's sense to keep up balance. If the cells of this part of the brain get damaged in consequence of depleted oxygen will cause dizziness and lack of balance.

3. Sudden confusion
A sudden onset of confusion means that something is potentially going wrong with the brain. Virtually 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 could also be due to lowered blood sugar, as is the case of diabetes.

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

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

7. Sudden trouble seeing
This may be an early on indication of stroke when the oxygen in the blood supply to the portion of the brain is suddenly interrupted or whenever a blood vessel in the mind bursts, spilling blood into cells that control the vision area 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 our body. apakah penyakit stroke bisa sembuh total? Most people of this generation already have some form of cholesterol building up within their arteries and raised blood pressure resulting in an increased risk of stroke.

2. Heredity
People with a family history of stroke have a larger chance of stroke than those don't have such a family history.

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

4. High blood pressure
High 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 together with increasing the risk of stroke.

5. Smoking
Smokers may be subjected 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 will help to increase the circulation of blood as well as providing more oxygen for cells. However, excessive drinking not only damages the standard function of liver but additionally raises raised blood pressure, increasing the risk of stroke.

7. Diabetes
Diabetes with unhealthy diet causes high degrees of glucose in the bloodstream. Diabetics have a larger threat of stroke, because high degrees of glucose damage the arterial wall and also clotting the arteries and arteries.

8. Gender
Males have a 20% greater threat of stroke than females.

IV. Types of Strokes

There are 2 forms of strokes:

1. Ischemic stroke the effect of a clot or other blockage within an artery leading to the brain.

2. Hemorrhagic stroke caused by the vessel in the brain rupturing in consequence of blood leaking into the brain.

1. Ischemic stroke
This is the most common type of stroke accounting for nearly 80% of all strokes. The brain depends on its arteries to bring fresh blood from the heart 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 your brain cells may not receive enough oxygen. Then they cannot make enough energy and can eventually stop working.
There are 2 types of Ischemic stroke

a)Thrombotic stroke.

If blood clots from the within of the arteries of the brain, we have thrombic stroke.
Study shows that this kind of stroke is responsible for almost 50% of all strokes. The most common problem is narrowing off the arteries in the neck or head. Thrombotic stroke may also be sometimes known as large-artery strokes. The process leading to thrombotic stroke is complex and occurs over time. Thrombotic stroke might be caused by the arterial walls slowly thickening and hardening as a result of arteries being injured. Such injures signal the disease fighting capability to release white blood cells to the website causing stroke. Thrombotic stroke also occurs when the inner wall of arteries were injured in consequence of less nitric oxide being produced, causing the hardening of the arteries. If the blood clot then blocks the already narrowed artery and shuts off oxygen to section of the brain, we've 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 cases like this the clot was formed somewhere other than in the brain itself.
The clot then travels the bloodstream until they become lodged and may not travel any further. This naturally restricts the flow of blood to the mind and results in embolic stroke. An embolic stroke occurs whenever a blood coagulum 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 blood vessels until it becomes wedged within an artery. It is also due to irregular beating in the heart's two upper chambers. This abnormal heart rhythm can lead to poor blood flow and the formation of a blood clot.

2. Hemorrhagic stroke
Hemorrhagic stroke occurs when a blood vessel bursts inside the brain, causing a rise of the fluid pressure on the brain and harms the brain by pressing it against the skull. Hemorrhagic stroke is connected with raised blood pressure, which stresses the arterial walls until they break.
There are 2 types of hemorrhagic strokes:

a) Intracerebral hemorrhage:

Intracerebral hemorrhage is internal bleeding that may happen in any the main brain. Blood may accumulate in the brain tissues itself, or in the space between the brain and the membranes covering it. Most commonly the problem arises in the small arterial inside the brain which have been diseased causing these tiny blood vessels 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 symptoms of an intracerebral hemorrhage and frequently increases over minutes or hours. People may not notice the problems associated with bleeding into the brain and ischemic strokes.

b) Subarachnoid hemorrhage

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