Each year, around 800,000 people have a new or recurrent stroke. The characteristics include face drooping or feeling numb, difficulties speaking, and muscle weakness on one side of the body. Stroke is caused from reduced or interrupted blood supply to the brain. There are ischemic strokes (thrombic and embolic strokes), hemorrhagic strokes (intracerebral hemorrage and subarachnoid hemorrhage), and transient ischemic attack (TIA). Chemically, in the brain an artery may be blocked by blood cells or a blood vessel could leak or burst causing a stroke. The symptoms of stroke
include the following: trouble with walking, headache, trouble with speaking and understanding, and trouble with seeing in one or both eyes.
The different
A stroke occurs when there is a sudden decrease in blood flow to a localized area in the brain (Trakalo, 2015, p.1234). This can occur in different ways such as a thrombus, an embolus, a stenosis, or a hemorrhage - all of which can cause devastating neurological effects depending on the extent of ischemia and necrosis resulting from the decreased oxygen carried by the blood.
* 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.
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 cause of a stroke could be an artery that is blocked. It is also referred to as an ischemic stroke. A stroke could also be caused by a blood vessel that has burst or is leaking, which is known as a hemorrhagic stroke. Some can experience an interruption in blood flow through their brain, which is known as transient ischemic attack (TIA). Ischemic strokes are the most common. When an ischemic stroke happens, arteries to the brain get narrowed or blocked, which causes a dramatic reduction of blood flow. There are two types of ischemic strokes. One of them is called a thrombotic stroke. A stroke that is thrombotic takes place when a blood clot forms in an artery
Stroke is a serious medical condition. It is life threatening as it is connected to the brain. Once the blood supply of the brain is cut to the part of the body then that particular part will have weakness. Just like our organs the brain also needs oxygen supply to work. If the blood is restricted, then the blood cells will start to die. The brain needs nutrition to work and blood is one way the brain can receive the nutrition it needs to function. A stroke is basically an attack on the brain and the people suffering from stroke can have a disability, brain injury and possibly death. When a person has a stroke this could only be for two reasons. One of the first causes for the stroke could be because of blood clots and this will stop blood
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.
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
Strokes are one of the major causes of immobility in seniors. Recovery largely depends on the extent of the brain injury and the length of time before treatment. Nonetheless, most seniors require the assistance of a caregiver and this mainly requires planning and organization. Here are some ways you can take care of a senior post -stroke
A stroke is a sudden stop in brain function. Approximately 25% of all people who get a stroke will have another in about five years time. The symptoms that occur are mainly affecting the nervous and digestive system, however, they may also have an effect on the other systems. Having a stroke will indeed affect the body’s functions extremely negatively. Affecting many parts of the body, strokes are devastating to the human race, killing many. The types of strokes, symptoms, and predictably will be covered.
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 is a type of cardiovascular disease that affects the cerebral arteries, those blood vessels that carry blood to the brain. A stroke occurs when one of those blood vessels in the brain is obstructed or ruptures flooding the brain with blood. Depriving blood and oxygen to the brain results in those immediate cells death, causing the brain not to function properly. Once parts of the brain stop functioning, it can directly affect the areas of the body controlled (1).
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
There are two different causes of strokes, the first is when the flow of blood to the brain is temporarily stopped due to a clot. The second is when one of the many vessels in the brain bursts and the blood from it leaks into the brain. Blood is essential in the brain as it carries oxygen, nutrients and minerals. Therefore, this short term lack of blood can cause serious injury to the brain, often resulting in death. However, if the person survives, their brain will be damaged and it can affect their way of life drastically.
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.
A stroke occurs when an area of the brain has died. Dr. Nicholson explained that this happens when there is a blockage in a blood vessel that supplies that particular area of the brain, or the blood vessel ruptures and leaks into the brain preventing the area from getting blood. As a result the area dies from lack of oxygen and nutrients. A bleeding blood vessel has a higher rate of
