Stroke can be caused either by a break of a blood vessel or a blood clot that travels and makes to one of the blood vessels in the brain causing brain tissue death (. It is the third leading cause of death and disabilities next to heart disease and cancer in the western world. The incident of ischemic stroke increases exponentially as the age is greater than or equal to eighty. There are risk factors that are known causes of stoke such as hypertension, atrial fibrillation, and post- surgical procedures. The mortality and morbidity increases depending on how many times the incident of stoke re-occurs decreasing the chance of survival; thus this
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.
A cerebrovascular accident more commonly known as a stroke or brain attack is the term used to describe the sudden death of brain cells in a localized area due to inadequate blood flow. In order to woke the brain needs a constant supply of oxygen and nutrients. This supply is carried to the brain
Stroke is a result of improper blood circulation in the brain. It is the major reason for disability and death worldwide.
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 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.
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
Ischemic strokes are the most common form of stroke, with around 85% of strokes being of this type. They are caused by the arteries that connect to the brain becoming blocked or narrowed, resulting in ischemia - severely reduced blood flow.
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 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.

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
Signs of a stroke are blurred vision or most commonly blurred speech. One could lose their balance or unable to walk. Most strokes are caused by a blood clot in the brain.
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.
