Those experiencing hypoglycaemia may exhibit aphasia--the inability to use or understand words. Hypoglycaemia can also produce hemiplegia, the inability to control motor functions, often on just one side of the body. Tumours or masses occurring in the central nervous system or brain can also mimic a stroke. Although masses typically increase in size progressively over time, the onset of symptoms may be sudden, just as a stroke. As the mass impedes on the brain or blood vessels, symptoms such as seizures and speech problems can occur.
Cerebrovascular Accident By Mike Smith RADT153 Radiography Patient Care Cypress College Just what is a cerebrovascular accident (CVA) one might say? A cerebrovascular accident otherwise known as a stroke occurs when the blood supply leading to the brain is interrupted or reduced; causing the tissue in the surrounding area to become oxygen deprived, which can lead to brain damage. This can be caused either by a type of blockage, known as ischemic stroke or by a rupture in a blood vessel, a hemorrhagic stroke. There is also a condition called a transient ischemic attack, where the individual for a brief period of time shows symptoms that are similar to a stroke. About 85 percent of strokes are ischemic strokes (Stroke, 2014).
Although there a small amount of cases of Alzheimer’s and frontotemporal dementia can be inherited from a previous generation. Vascular dementia is where the blood supply to the brain is interrupted, if there is restricted or stopped blood supply to the brain that’s when the cells being to die which results in brain damage. * Alzheimer’s disease Alzheimer’s is the most common form of dementia, this form of the disease is the loss of cells in brain which causes the brain to shrink. The medical term for this is ‘Atrophy’. The most affected part of the brain is the Cerebral Cortex; this part
Describe the mechanism(s) by which strokes occur. Cerebrovascular Accident- condition in which brain tissue is deprived of blood supply. The most common stroke symptoms are: • Numbness or weakness (paresis) of the face, arm, or leg, sometimes only on one side; • Confusion, trouble speaking or understanding speech (aphasia) • Trouble seeing • Trouble walking or dizziness; loss of balance or coordination (ataxia) • Severe headache with no known cause 1. Ischemic stroke (~83%)- blood vessel supplying brain tissue is blocked by a blood clot a. cerebral thrombus b. cerebral embolism 2. Hemorrhagic stroke (~17%)- A blood vessel breaks open, causing blood to leak into the brain 3.
Outcome 1 Know what a stroke is 1.1 Identify the changes in the brain associated with stroke Heart attacks and strokes are usually due to cardiovascular disease, a condition featuring body-wide damage to the delicate lining of the arteries the tubes that carry oxygen and nutrient-rich blood to all the organs, tissues and cells in your body and to the brain. The psychological, behavioural and emotional changes that take place after a stroke are part caused by physical damage to the brain. When the brain cells are damaged the sensations and parts of the body controlled by the cells can no longer function properly. This usually affects the left hand side of the body. But I personally have seen someone who has had a stroke and it has
Symptoms of a thrombosis stroke come up more gradually and often come unnoticed. Some of the common symptoms of a stroke include blurring and decrease vision in one or both eyes, severe headache, and weakness, and numbness, paralysis of the arm or leg usually confined to one side of the body, dizziness, and loss of balance or coordination (Yatsu, 2002). An initial diagnosis of a stroke is made on observations by the nurse or doctor, and by a neurological examination. Once a stroke is suspected, a computed tomography (CT) scan or magnetic resonance imaging (MRI) scan is preformed to distinguish if a stroke was from a blood clot or a hemorrhage ( Schonbeck, 2006). Blood and urine test are taken to look for any abnormalities associated with activity within the body cavity.
Stroke Questions 1) What happens to the body as a stroke occurs? A stroke is when the flow of blood to the brain stops. A stroke causes damage to the brain and brain cells in the immediate area which then begin to die because they are not getting the oxygen and nutrients they need to survive. 2) Name three different types of Stroke? Ischaemic stroke, which is caused by a blood clot that blocks a blood vessel or artery in the brain.
2. Many factors may affect fluid input and output medical conditions such as congestive cardiac failure, renal failure, high sodium intake and cirrhosis of the liver. Also the type of anaesthesia used will contribute to the input/output of fluids. Wound drainage could be affected if the patient has an un-diagnosed clotting disorder, infection, or an amniotic embolism. A patient who has had multiple surgeries could also cause a lot of tissue damage and could increase the patients blood loss.
This may be as a result of a stroke or mini strokes although it can be caused by preventable conditions such as high blood pressure, diabetes and high cholesterol. Dementia with Lewys Bodies (DLB) is caused by small deposits of proteins found in the nerve cells of the brain. Their presence in the brain leads to the degeneration of brain tissue. This is the third most common form of dementia. Rarer forms of dementia are: Fronto temperal dementia which is brain damage usually focused in the front or temporal parts of the brain.
There are a number of different types of vascular dementia. Two of the most common are: Multi-infarct dementia – caused by a number of small strokes, called mini-strokes or transient ischaemic attacks (TIA). This is probably the most common form of vascular dementia. Binswanger’s disease (also known as subcortical vascular dementia) – associated with stroke-related changes to the brain.
