Strokes are the third leading cause of death in the U.S., accounting for 140,000 deaths each year in the U.S., and over 5 million worldwide. They are caused by blot clots or vessel ruptures in the brain, causing the death of surrounding brain cells. There are two types of strokes: ischemic strokes and hemorrhagic strokes. Ischemic strokes are caused by blot clots that form in the brain, called thrombotic strokes, or form in other body parts and travel to the brain, called embolic strokes. This type of stroke accounts for 87 percent of all stroke cases. Hemorrhagic strokes are caused by the bursting of cranial arteries inside the brain, called an intracerebral hemorrhage, or near the surface of the brain, called subarachnoid hemorrhage. These account for the other 13% of stroke cases. There are no clear causes for strokes, but there are many risk factors. Some lifestyle risk factors include obesity, sedentary lifestyles, heavy or binge drinking, smoking or exposure to cigarette smoke(which can double your risk), and usage of illegal drugs. Some medical risk factors include blood pressure higher than 120/80, high cholesterol, diabetes, obstructive sleep apnea, any cardiovascular disease, and a family history …show more content…
Whole body symptoms include balance disorder, fatigue, lightheadedness, or vertigo. Visual symptoms include blurred vision, double vision, sudden visual loss, or temporary loss of vision in one eye. Speech symptoms include difficulty speaking, slurred speech, or speech loss. Sensory symptoms include pins and needles or reduced sensation of touch. Facial symptoms include muscle weakness or numbness. Limb symptoms include numbness or weakness. Other common symptoms include difficulty swallowing, headache, inability to understand, mental confusion, or rapid involuntary eye
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
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.
A stroke can be generally be defined in two types of categories. The first and most common type of stroke is called ischemic stroke. This occurs when a blood clot (cerebral thrombosis) blocks a blood vessel in the brain. Blood flow beyond the blood clot is then
There are three types of strokes that cause changes to the brain: Hemorrhagic stroke,Intracerebral hemorrhage and Transient ischemic attack (TIA). Ischemic stroke is the most common form of stroke, accounting for around 87% of strokes.
In the initial symptoms which are the most common are having difficulty in walking, numbness(pins and needles) and eyesight becoming worse. The less common syptoms consists of tremor, loss of coordination, speaking disorders, paralysis, not being able to think, reason or even remember. Finally all the others are rarely to happen(uncommon) and they are dizziness, difficulty while swallowing, constant headaches, problems hearing, itchiness, pain, seizures, sexuality problems.
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.
Strokes are caused by pathophysiological changes. The two major mechanisms of stroke consist of ischemia and haemorrhage. Ischemia is when there is no oxygen or not, merely enough oxygen to fuel the tissue level in the body. Haemorrhage in the brain, causing strokes can be due to non-traumatic intracerebral haemorrhage (Shah, MD, n.d.) (see appendix 1). This essay will further discuss the implications of strokes on a cellular, organ and system level. Explain the clinical presentation of the signs and symptoms of strokes and how the condition will be managed by a paramedic.
The risk factors for stroke can be classified into non-modifiable and modifiable. Non-modifiable risk factors include age, family history, prior stroke, gender, and race. Whereas modifiable risk factors are hypertension, diabetes mellitus, coronary artery disease, atrial fibrillation, dyslipidemia, cigarette smoking, obesity, valvular heart disease, alcohol abuse, and physical inactivity (Basharat et al., 2012).
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
A CVA occurs when a part of the brain is damaged or destroyed due to an interruption of blood flow to the area resulting in brain cell death (Martini, Nath & Bartholomew 2015 pp. 496-470).There are two main types of a CVA, Ischaemic stroke and Haemorrhagic stroke (AIHW 2013). The most common cause of stroke is ischaemic, which can be caused by embolism/thrombosis (AIHW 2013). An embolism/thrombosis occurs when there is a clot in an artery or vein, which stops blood flow to the brain (AIHW 2013). A haemorrhagic stroke is when an artery ruptures and bleeds into the surrounding brain tissue (AIHW 2013). This form of stroke occurs when blood pools and forms a clot therefore putting pressure on the area of the brain depriving it of oxygen and nutrients it needs to remain healthy (AIHW 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
Stroke is often related to other genetic diseases or disorders. Stroke occurs by blood flow being interrupted to the brain by either a clot or a bleed on the brain. The brain cells die quickly if blood flow is blocked (Centers of Disease Control and Prevention, 2016a). Ischemic stroke occurs when blood flow is blocked by clots or particles (CDC, 2016a). Hemorrhagic stroke occurs when the brain has a bleed from blood vessels bursting (CDC, 2016a). Stroke can leave individuals with deficits and dependent on others for care. Stroke can cause death.
Hemorrhagic stroke occurs when a blood vessels in the brain leaks or ruptures. Bleeding from the ruptured brain artery can either go into the substance of the brain or into the various spaces surrounding the brain. The two types of hemorrhagic stroke are Intracerebral and Subarachnoid hemorrhagic.
A stroke caused by a blocked artery by a blood clot or bursting of a blood vessel because of uncontrolled high blood pressure. There are main three types of the stroke. An ischemic stroke occurs when a blood clot blocks one of the arteries which supply blood to brain. A clot may be caused by fatty deposits (plaque) that build up in arteries and cause reduced blood flow (atherosclerosis) or other artery conditions. (mayo clinic). About 89%, strokes are ischemic strokes. Ischemic stroke includes thrombotic stroke. A thrombotic stroke occurs when a thrombus stuck in one of the arteries that supply blood to the brain. A clot build-up of fatty deposits in arteries. Another type of stroke is called the hemorrhagic stroke. This stroke occurs when a blood vessel leaks or ruptures in the brain. A bold vessel leaks or ruptures from many conditions like uncontrolled high blood pressure or overtreatment with anticoagulants and the weak spot in blood vessel walls. (mayo). Some people experience a mini-stroke it is known as a transient ischemic attack (TIA). A temporary decrease or clot stuck in a vessel in our brain causes TIA. It happens less than five minutes. This stroke does not have any symptom, because the blockage is
