Causes Of Strokes

     The most common causes of strokes are thrombosis. This is when a clot forms in one of the arteries, mostly in the carotid in the neck and the vertebral artery. The blood is thick and moves very slowly through the artery. The thrombus will form on the damaged area of the artery wall and will cut off the flow of blood to the brain. The area of the artery that is damaged is cause by arteriosclerosis. This form of

There are two major branches of strokes: those caused by narrowing or blockage of the arteries leading towards the brain, and those caused by blood vessel leaking or rupturing in the brain. Ischemic strokes account for approximately 87% of Stroke cases, which reduces the blood flow to the brain. About half of the Ischemic strokes are caused by clotting in small or large arteries, a smaller portion are caused by

An ischemic stroke is typically caused by a thrombosis, which is a blood clot or an embolism, when the blood clot detaches and infiltrates the blood stream.

In many cases, strokes can be diagnosed, prevented and treatable. Symptoms of a stroke can occur quickly and may cause: sudden numbness, tingling, or weakness, or paralysis in your face, arm, or leg, especially on one side of your body. Sudden: vision changes, trouble speaking (slurred speech), confusion or trouble understanding simple statements, problems with walking or balance, severe headache. It's recommended to call a doctor or 911 even if these symptoms last for a short amount of time because a transient ischemic attack, or mini stroke may have occurred. The transient ischemic attack may be a precursor to a stroke occurring soon. Catching these symptoms can dramatically increase chances of prevention additional damage to the body (2).

Strokes are the 5th leading cause of death in the US, with one person dying every 4 minutes as a result. For African Americans, stoke is the 3rd leading cause of death.(http://www.cdc.gov/stroke/facts.htm) It is estimated that About 795,000 people have a stroke each year; about one every 40 seconds - there are many medical conditions that can cause a stroke and it is estimated that 8 out of 10 strokes can be prevented. However, there are some things that cannot be controlled when you are predisposed to

There are several different types of stroke and it does not affect everyone the same. According to Mayo

A stroke can be brought on by many different factors like age, gender and family history – all of which one cannot control. Others are lifestyle factors like high blood pressure, high cholesterol, smoking, obesity or being over weight, poor diet, lack of exercise and drinking too much alcohol (stroke foundation Australia). Currently there is no universally accepted treatment (Ward, 2005).

Stroke is like a heart attack, but instead the problem is with the brain not the heart. Stroke happens when the blood that is suppose to go to the brain is blocked or reduced. When the blood supply to the brain is blocked or reduced, the brain doesn’t get enough oxygen or nutrients, which causes brain cells to die. It can also be because of smoking. Smoking creates blood clots in the artery. Stroke is the top 5 disease that caused death in the US, but for black people stroke is the top 3 disease that caused death. Stroke commonly occurs to people over the age of 65. Even though the risk of having a stroke is high over the age of 65, stroke can occur at any age. Approximately 15 million people suffer from stroke each year. 5 million of these

Lastly, Ischaemic stroke is fatal in one third of cases, making it the third most common cause of death in developed counties (Nedeltchev & Mattle 2014, pp. 124-129). Among the survivors of stroke, at least half are permanently disabled, making stroke a major cause of long-term physical, cognitive, emotional, and social disability (Redfern, Mckevitt & Wolfe 2006, pp. 123-141). However, there has been a reduction in stroke deaths over the last ten years due to an increase in public awareness through programs and education around reducing risk factors for stroke (AIHW 2013). These programs targeted specific causes, such as; smoking,

A stroke is a condition which is characterised as loss of brain functioning due to an interruption in the blood flow to the brain (Buzzard, 2013, pg. 5). There are two types of strokes, ischaemic and hemorrhagic strokes (Buzzard, 2013, pg. 6). Ischaemic strokes are the most common type of stroke (Gomes & Wachsman, 2013). This type of stroke occurs due to an insufficient flow of blood to the brain, which is usually caused by an artery blockage (Gomes & Wachsman, 2013). Hemorrhagic strokes are due to hypertension and may be caused by medical problems or blood vessel abnormalities (Gomes & Wachsman, 2013). The strokes severity and location of the brain that is affected determines the impact of the stroke in an individual (Gomes & Wachsman, 2013).(Gomes, 2013)

Sometimes known as a brain attack, a stroke occurs when blood flow to the brain stops. Brain cells immediately start to die due to the lack of oxygen and nutrients they need to function. There are two types of strokes. The most common type, called ischemic stroke, is caused by a blood clot that blocks a blood vessel in the brain. The other kind of stroke, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. Stroke is the fourth leading cause of death for Americans ("What You Need to Know About Stroke," 2013). In fact, according to the CDC, more than 795,000 people in the United States have a stroke every year ("Stroke Facts," 2015). A stroke can cause great damage in the brain and lead to mild or severe

A less common type of stroke is a hemorrhagic stroke. This type of stroke occurs when the artery that supplies blood to the brain ruptures or bursts. Stroke is an expensive disease with lifetime rehabilitation costing over $140,000 per ischemic stroke with higher costs for subarachnoid hemorrhage (Alberts, et. al. 2011). Although stroke risk increases with age, strokes can occur at any age. In 2009, 34% of people hospitalized for stroke were younger than 65 years (Hall, 2012). More women than men have strokes each year, in part because women live longer. Estimates of the overall incidence of stroke in U. S. children are 6.4 per 100,000 (0-15 yrs.) with approximately half being hemorrhagic stroke (ASA, 2016). African Americans are more impacted by stroke than any other racial group within the American

Recently, there has been a surge in reports of TIAs in rare instances such as healthy, young women. With lack of full understanding as to the reasoning behind this, research found that strokes are not a geriatric disease as once believed (stroke association.org). Accordingly, Steven J. Kittner, M.D., director of the Maryland Stroke Center at the University Of Maryland School Of Medicine in Baltimore declares that strokes can affect anyone at any age (2004). Furthermore, he states that although there are common risk factors, some of the more hidden ones are the most dangerous, especially for women under 55 (Kittner, 2004). He claims, matching other reports that these hidden risk factors leading to increased strokes include: migraines, oral contraceptives,

Stroke is defined as a focal neurological impairment of sudden onset, lasting more than 24 hours, with the possibility of death. Strokes are the third leading cause of death and adult neurological disability. A few factors that could trigger a stroke include age, race, obesity and hypertension. Genetics are a huge factor when it comes to stroke. As stated by John Francis, “Studies have shown that genetic factors account for 50% of strokes.” High blood pressure, heart disease, vascular conditions and diabetes are all stroke risk factors that family history play a part of. FDA.gov states that “children with parents, grandparents, sisters or brothers who have had a stroke by the age of 65 are at greater risk of having one themselves.” “They are more common in men than they are in women, approximately 62% more women die from a stroke than men” said my Dr. James Faber. A mother’s stroke will strongly effect their daughter, a father’s stroke is likely to impact both their sons and/or daughter equally.” From birth, your genetic make-up is already fixed. Stroke is like a notch that’s hidden within the body that plays a role in call fate and development. This notch also has a huge impact on the arteries and blood vessels in the brain. The blood supply to the brain comes from four blood vessel, the left and right carotid arteries, and the left and right vertebrobasilar arteries. Depending on how strong the stroke notch is in your family will help determine if one minor

What is a stroke and how is it related to the aging brain? A stroke happens when the blood supply to your brain is interrupted or it is reduced, depriving the brain tissues of oxygen and food (Bendheim, P.E. (2009). Within minutes of a stroke brain cells begin to die. Early action can minimize brain damage and potential complications. A stroke can cause temporary or permanent disabilities, depending on how long the brain suffers the lack of blood flow (Perlmutter, David. (2004). Some complications after a stroke are; paralyzation (loss of muscle movement), memory loss, and trouble talking. Paralyzation is due to the lack of blood flow to the brain, a patient can lose movement in one side of the body. Stroke can damage too many parts of the brain, and it can start an early brain aging. A stroke can cause a patient to loss control over the way muscles in the mouth move, have difficult talking and eating (Bendheim, P.E. (2009). But one can try to prevent a stroke by taking care of their high blood pressure, high cholesterol, and smoking.
