The sudden death of brain cells due to lack of oxygen, caused by blockage of blood flow or rupture of an artery to the brain. Sudden loss of speech, weakness, or paralysis of one side of the body can be symptoms. A suspected stroke may be confirmed by scanning the brain with special X-ray tests, such as CAT scans. The death rate and level of disability resulting from strokes can be dramatically reduced by immediate and appropriate medical care. Prevention involves minimizing risk factors, such as controlling high blood pressure and diabetes. Abbreviated CVA. Also known as cerebrovascular.
Medications like tPA (clot buster) can minimize brain damage. Other treatments focus on limiting complications and preventing additional strokes. Here are

Also balance disorder, fatigue, lightheadedness, or vertigo.Here are some more muscle weakness or numbness and numbness or weakness. difficulty speaking, slurred speech, or speech and pins and needles or reduced sensation of touch.Finally difficulty swallowing, headache, inability to understand, mental confusion, or rapid involuntary eye movement.
Age matters because the likelihood of having a stroke nearly doubles every 10 years after age 55. Although stroke is more common among the elderly,a lot of people under 65 also have strokes. A list of risk for a stroke high blood pressure,diabetes,heart diseases,smoking,and brain aneurysms or arteriovenous malformation (AVMs). Sudden numbness or weakness of the face,arm or leg,especially on one side of the body. Some people who have a stroke recover quickly and can regain normal function of their body after just a few days.
Strokes are also more likely to be fatal and strike earlier in men than in women. The consequences of a stroke can be devastating. Not only can a stroke kill you, but nonfatal strokes can leave you severely debilitated, paralyzed, or unable to communicate. When stroke causes pain, it usually occurs as a sudden and severe headache. The most common stroke type is ischemic (blockage) stroke, typically is not painful. Ischemic strokes cause weakness, language, visual and other brain problems, but little or no
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
* Cerebrovascular Disease: More commonly known as stroke cerebrovascular disease can be cause by either a colt or blockage that cuts off blood flow to a part of the brain or by haemorrhage. In both cases there is damage or death of the brain tissue that can cause paralysis, speech disorder, swallowing problems and immobility. People with diabetes and high blood pressure are at higher risk of stroke.
Stroke also known as cerebrovascular accident (CVA), cerebrovascular insult (CVI), or a brain attack. A brain attack is the loss of brain function by the cause of disturbance in the blood supply to the brain. This disturbance occurs due to either one of two causes which are ischemia (lack of blood flow) or a hemorrhage (high increase of blood flow directly into brain; parenchyma or into the subarachnoid space which surrounds the brain with tissue). Ischemia is a formation by a blood clot that is inside of a blood vessel located in the circulatory system called thrombosis or arterial embolism; which is a rapid interruption in the supply of blood flow to an organ or body part due to a clogged artery blocking the blood flow. Thrombosis is a
As stated in Acute Stroke Intervention (Prabhakaran, Ruff, & Bernstein, 2015), one of the leading causes of death and disability in the United States are strokes. Acute ischemic stroke (AIS) results when an artery that is supplying the brain becomes blocked, this occurrence leads to cell death of brain tissue. Improving brain function after an ischemic stroke is of high priority for clinical research. General consensus shows that administration of intravenous recombinant tissue plasminogen activator (IV rtPA) therapy is helpful when introduced within 4.5 hours of ischemic stroke symptom onset. The benefit of intravenous (IV rtPA) lessens when the onset of symptoms goes beyond 4.5 hours. The use of (IV rtPA) is contraindicated when there is
A stroke occurs when the blood supply to the brain is blocked. The tissue does not get enough of oxygen and nutrients within minutes, the brain cells begin to die. A stroke is a medical emergency, and prompt treatment is crucial. The good news is a stroke can be treatable and is more preventable. More people live longer now than in the past years. Stroke is known as the silent killer. Many people ignore the symptoms and cause more damage to their body. People with stroke have trouble speaking and understanding, paralysis or numbness of the face arm or leg. If you ever encounter anyone with these systems, please call 911 imminently for help.
Cerebral Vascular Accident also known as a stroke, happens when the artery that supplies the blood flow to your brain becomes substantially blocked or completely blocked ("Overview - Stroke - Mayo Clinic," 2015). Without adequate blood supply the brain cells begin to die or become damaged. It is very important to get medical assistance as soon as you think you may be having a stroke, this will help lessen the damage done to the brain ("Overview - Stroke - Mayo Clinic," 2015).
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
1. Every 40 seconds someone in the United States has a stroke (National Stroke Association, 2014). Some symptoms related with a stroke are headache, blurred vision, trouble speaking, confusion, dizziness and numbness on one side of body. These symptoms are very important to know. Due to how common strokes are it's good to know the warning signs. For every person that dies from stroke, more than 5 times that many will survive, and for them the physical damage it causes can be enormous (National Stroke Association, 2014). Most people who have a stroke are depressed after it's all said and done. They may be paralyzed on one side, have a speech impairment or worse. When you are used to living a certain way and that suddenly changes it can be hard for people to deal with.
Strokes are caused by a block in the blood supply to the brain which causes a decrease in oxygen and delivery of other important supplies which facilitate proper functioning. Fifteen million cases are reported worldwide annually, although not all of these cases are mortalities, the large prevalence of strokes ranks it as the fourth leading cause of death in the United States. (Figueroa) Because of the time sensitivity associated with the lack of resources to the brain, strokes are considered a medical emergency and early recognition of symptoms can help decrease the amount of damage caused . Although strokes do not always cause death, strokes most often leave the individual with some physical and cognitive impairment.
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 fifth leading cause of death for Americans. In fact, according to the CDC, more than 795,000 people in the United States have a stroke every year. A stroke can cause great damage in the brain and lead to mild or severe disabilities to the entire body such as paralysis, difficulties with
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)
The primary purpose of non-enhanced CT in acute stroke is to exclude haemorrhage and neoplasm and to asses the extent of cerebral ischemia which would render thrombolysis contraindicated due to the significant risk of doing more harm than good. Once the non enhanced CT has confirmed absence of these findings thrombolyic agent should be administered to the acute stroke patient in the radiology department. If the extent of cerebral ischemia extends to greater than one third of the distribution of middle cerebral artery thrombolysis may be contraindicated. Time is Brain there should be no delay in reperfusion.
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).
Cerebral vascular accident or a stroke is the destruction of brain substance, resulting from thrombosis, intracranial hemorrhage, or embolism, which causes vascular insufficiency. In addition, it is an area of the brain denied blood and oxygen that is required and damage is done to a part of the cells. The effect of the patient depends upon where the damage occurs and the severity of the stroke.
Numbness, weakness, immobility, inability to feel one side of your body, speaking and understanding problems, loss of vision to one side and strange feelings (like the world is spinning), uncoordinated balance and dizziness areamong the many symptoms of stroke. Hemorrhagic stroke is often indicated by severe headache. Long-term and permanent complications may be experienced.
