Besides cancer and heart diseases, stroke may be the third leading cause of death. Approximate 1/4 of most 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. Basically, if cholesterol building up in the arteries is blocking the blood circulation in any part of the body causing oxygen not to be delivered to the mind, leading to some cells in the brain to die off and are unable reproduce, then we’ve stroke. Other strokes happen when a blood vessel in the mind ruptures causing the cells in the human 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 some causes of stroke:
1. Unhealthy diet
A diet saturated in saturated and trans fats causes bad cholesterol to develop in your arteries in the brain, blocking oxygen necessary for the cells thus increasing the chance of stroke. Also unhealthy diet causes raised blood pressure making your heart work harder to pump blood to your system in consequence of heart diseases. High blood pressure also causes the arteries in your brain to harden and thin, increasing the risk of stroke.
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 circulation and damaging the arteries 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 risk of stroke.
People with diabetes have a tendency to develop cardiovascular disease or have strokes at a youthful age than other people. Diabetes with unhealthy diet causes high blood glucose levels that damage nerves and blood vessels, leading to complications such as for example 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 exercise; obesity is still of a greatest risk of stroke in people.
6. Use of contraceptive pills
Birth control pills contain estrogen and one 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 notable 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 can be an early symptom of stroke as a result of circulation of blood that carries oxygen to suddenly deplete caused by narrowing of arteries and high blood pressure.
2. Dizziness and loss of balance
The mind coordinates information from the eyes, the inner ear, and your body’s sense to maintain balance. If the cells of this area 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 brain. Almost all conditions that affect the brain are life-threatening. It may 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 caused by lowered blood sugar, as is the case of diabetes.
4. Having trouble speaking and understanding
Having trouble speaking and understanding occurs once the brain cells in your community of the broca, wernicke and angular ayrus in the left hemisphere area begin to die because they stop obtaining the oxygen and nutrients they need to function.
6. Sudden severe headaches
Headache is a condition of pain in the head, sometimes neck or spine pain can also be interpreted as a headache. It ranks between the most common local pain complaints and may be frequent for most 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 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 circulation to the the main brain is suddenly interrupted or whenever a blood vessel in the mind bursts, spilling blood into cells that control the vision section of the cerebral cortex in the mind.
III. The Risk Factors
Human aging may be the biological process that is unavoidable but controllable. Starting at age 40, the cells inside our body begin this process causing the deterioration of some functions of the body. Most people of this generation already have some form of cholesterol building up in their arteries and high blood pressure resulting in an increased risk of stroke.
People with a family group history of stroke have a greater chance of stroke than those don’t have such a family history.
Because of frequent raised blood pressure in African Americans, they have a significantly higher risk 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 our body resulting in heart diseases and also increasing the risk of stroke.
Smokers may be subjected to toxic cadmium, causing high blood pressure and heart diseases along with 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 might help to increase the blood circulation as well as providing more oxygen for cells. However, excessive drinking not merely damages the normal function of liver but additionally raises high blood pressure, increasing the risk of stroke.
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 along with clotting the arteries and blood vessels.
Males have a 20% greater threat of stroke than females.
IV. Types of Strokes
There are 2 types of strokes:
1. Ischemic stroke caused by a clot or other blockage within an artery leading to the mind.
2. Hemorrhagic stroke due to the vessel in the mind rupturing in result of blood leaking in to the brain.
1. Ischemic stroke
This is the most common type of stroke accounting for almost 80% of all strokes. The mind depends on its arteries to create fresh blood from the center and lungs. The blood carries oxygen and nutrients to the brain, and takes away carbon dioxide and cellular waste. If an artery is blocked then the brain cells might not receive enough oxygen. They then cannot make enough energy and can eventually stop working.
There are 2 types of Ischemic stroke
If blood clots from the inside of the arteries of the brain, we have thrombic stroke.
Study shows that this type 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 are also sometimes known as large-artery strokes. The process leading to thrombotic stroke is complex and occurs over time. 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 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 area 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 mind, 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 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 clot which has traveled through the blood vessels 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 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 against the skull. Hemorrhagic stroke is associated with high 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 section of the brain. Blood may accumulate in the brain tissues itself, or in the space between your brain and the membranes covering it. Mostly the problem arises in the small arterial inside the brain which were diseased causing these tiny blood vessels to start to leak. Because the actual source of the bleeding is often small, it can take time for the blood to develop resulting in symptoms of an intracerebral hemorrhage and often increases over minutes or hours. People may 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 common 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 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.
