Besides cancer and heart diseases, stroke is the third leading cause of death. Approximate 1/4 of all stroke victims die as a direct result of the stroke or it’s complications. Stroke is due to 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 accumulating in the arteries is blocking the blood circulation in any portion of the body causing oxygen never to be delivered to the mind, leading to some cells in the mind to die off and are unable reproduce, then we have stroke. Other strokes happen whenever a blood vessel in the brain 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, however in stroke the result is more serious. Any delay of rescuing will result in death of the victim. Here are several causes of stroke:
1. Unhealthy diet
A diet saturated in saturated and trans fats causes bad cholesterol to build up in your arteries in the brain, blocking oxygen necessary for the cells thus increasing the risk of stroke. Also unhealthy diet causes raised blood pressure making your heart work harder to pump blood to the body in consequence of heart diseases. Raised blood pressure also causes the arteries in the human brain to harden and thin, increasing the risk of stroke.
Smoking not only includes a devastating effect on the health of the smoker but also to anyone who inhales its toxic fumes. Cigarettes contain high levels of cadmium that triggers the blood to clot activity of cells in result of blocking blood circulation and damaging the blood vessels in the brain.
3. Excessive drinking
Moderate drinking is good for your heart, but excessive drinking can raise degrees of some fats in your blood causing cholesterol to develop in the arteries and arteries in the brain resulting in increase of the chance of stroke.
People with diabetes have a tendency to develop heart disease or have strokes at an earlier age than other folks. Diabetes with unhealthy diet causes high blood sugar levels that damage nerves and arteries, leading to complications such as heart disease and stroke, the leading causes of death among people with diabetes.
5. Obesity – a body mass index of 30 or more
Study shows that even with adjusting for other stroke risk factors such as high blood pressure, diabetes, raised chlesterol, smoking, cardiac diseases, moderate alcohol consumption, and exercise; obesity is still of a greatest threat of stroke in individuals.
6. Use of birth control pills
Birth control pills contain estrogen and one of two other hormones, lynestrenol or norethisterone that raise 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 notable causes of stroke such as heart diseases that we have discussed lengthily in the heart 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 due to blood circulation that carries oxygen to suddenly deplete caused by narrowing of arteries and raised 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 this section of the brain get damaged in result of depleted oxygen may cause dizziness and lack of balance.
3. Sudden confusion
An abrupt onset of confusion implies that something is potentially going wrong with the mind. Virtually all conditions that affect the mind are life-threatening. It may be caused by a tumor or low degrees of oxygen in the cells of the cerebral cortex in your brain that affect your capability to think together with your usual speed or clarity. It could also be due to lowered blood sugar, as may be the case of diabetes.
4. Having difficulty speaking and understanding
Having trouble speaking and understanding occurs when the brain cells in your community 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 may also be interpreted as a headache. It ranks amongst the most typical local pain complaints and could be frequent for many individuals but sudden severe headaches may be caused by an early on symptom of heart disease once 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 indication of stroke once the oxygen in the blood circulation 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 mind.
III. The Risk Factors
Human aging is the biological process that is unavoidable but controllable. Starting at age 40, the cells inside our body begin this process evoking the deterioration of some functions of our body. Most people of this generation already have some type of cholesterol building up within their arteries and high blood pressure resulting in an increased threat of stroke.
People with a family history of stroke have a larger potential for stroke than those do not have such a family history.
Because of frequent high blood pressure in African Americans, they have a significantly higher risk 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 our body resulting in heart diseases and also increasing the chance of stroke.
apakah penyakit stroke bisa sembuh total? Smoking
Smokers may be exposed to toxic cadmium, causing high blood pressure and heart diseases in addition to contributing to a higher threat of stroke.
6. Excessive alcohol consumption
Drinking one cup of wine for women and 2 cups of wine for men will help to increase the circulation of blood in addition to providing more oxygen for cells. However, excessive drinking not only damages the normal function of liver but also raises raised blood pressure, increasing the risk of stroke.
Diabetes with unhealthy diet causes high levels of glucose in the bloodstream. Diabetics have a greater threat of stroke, because high levels of glucose damage the arterial wall together with clotting the arteries and blood vessels.
Males have a 20% greater threat 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 mind.
2. Hemorrhagic stroke caused by the vessel in the brain rupturing in result of blood leaking in to the brain.
1. Ischemic stroke
This is the most typical type of stroke accounting for nearly 80% of all strokes. The mind depends on its arteries to create fresh blood from the heart and lungs. The blood carries oxygen and nutrients to the brain, and takes away skin tightening and 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
If blood clots from the within of the arteries of the mind, we have thrombic stroke.
Study shows that this sort of stroke is in charge of almost 50% of all strokes. The most frequent problem is narrowing off the arteries in the neck or head. Thrombotic stroke are also sometimes referred to as large-artery strokes. The process leading to thrombotic stroke is complex and occurs as time passes. Thrombotic stroke might be due to the arterial walls slowly thickening and hardening because of arteries being injured. Such injures signal the disease fighting capability release a 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 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 your 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 more. This naturally restricts the flow of blood to the mind and results in embolic stroke. An embolic stroke occurs when a blood coagulum or other particle forms in a blood vessel away from your brain. It is almost always caused by a dislodged blood clot that has traveled through the blood vessels until it becomes wedged in 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 forming of a blood clot.
2. Hemorrhagic stroke
Hemorrhagic stroke occurs whenever a blood vessel bursts inside the brain, causing an increase of the fluid strain on the brain and harms the mind by pressing it contrary to the skull. Hemorrhagic stroke is connected with raised blood pressure, which stresses the arterial walls until they break.
There are 2 forms 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 area 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 way to obtain the bleeding is frequently small, normally it takes time for the blood to build up resulting in outward indications of an intracerebral hemorrhage and frequently increases over minutes or hours. People might not notice the problems connected with bleeding in to 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 typical from age 40 to 65. It really 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 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 most limbs, unconsciousness and bleeding into the cerebellum produceing typical signs of in coordination with headache and stiffness of the neck.
