Clinically, a variety of facal deficits are possible including changes in the level of consciousness and impairments of sensory, motor, cognitive, perceptual and language functions. To be classified as stroke, neurological deficits must persist for at least 24 hours. Motor deficits are characterized by paralysis (hemiplegia) or weakness (hemiparesis , which typically on the side of body opposite the side of the lesion (cross motor deficit). It is a cross process. The terms hemiplegia is often used generically refer to the wide variety of motor problems that result from stroke.
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.
Etiology Retinal detachment can occur as a result of: * Shrinkage or contraction of the vitreous-the gel-like material that fills the inside of your eye. This can create tugging on the retina and a retinal tear, leading to a retinal detachment. * Injury * Advanced diabetes * An inflammatory eye disorder How retinal detachment occurs Retinal detachment can occur when the gel-like material (vitreous) leaks through a retinal hole or tear and collects underneath the retina. Reasons for holes or tears include: * Aging or retinal disorders can cause the retina to thin. Retinal detachment due to a tear in the retina typically develops when there is a sudden collapse of the vitreous, causing tugging on the retina with enough force to create a tear.
Vascular dementia is caused when there is a reduction in the blood flow to the brain. Over time, this can damage the parts of the brain which play a large part of a person memory, speech and attention. A stroke can play a part in this type of dementia when it narrows the blood vessels to the brain. Dementia with Lewy Bodies is caused by lumps of protein which builds up inside nerve cells inside the brain, the proteins damage the nerve cells and how they work, these nerves are responsible for thinking, memory and movement of a person. Dementia with Lewy Bodies can be closely related to Parkinsons Disease and there is a theory that Dementia with Lewy Bodies interferes with two neurotransmitters called dopamine and acetylcholine which assist in the brains functions.
This pain may become worse within minutes after eating or drinking, especially high fat foods. It may become constant and more severe, lasting for several days and may worsen when lying flat. The client with acute pancreatitis may appear ill with fever, nausea, vomiting, and sweating. Treatment often requires a stay in the hospital and may involve pain medication, IV Fluids, maintaining NPO status, to limit the activity of the pancreas and on occasion an NG tube to remove stomach contents. In some cases gallstones may be removed to relieve blockage of the pancreatic duct.
It is a physical condition affecting the brain. It can be caused by various things such as age, down syndrome and genetics. It is caused when abnormal clumps called either plaques or tangles interfere with how the brain cells work and communicate which cause them to die. People with Alzheimer’s also have a shortage of chemicals that help with the transmission of the brain. The symptoms of Alzheimer’s disease may change as the disease progresses.
The CVA can be a hemorrhage or thrombus and the severity of the lesion determines the loss of function. In extensive disease, neighboring neurons may also be affected. Following a stroke, the oxygen supply to brain cells is blocked and cells start to die within minutes. This will be reflected by symptoms like sudden weakness, paralysis or numbness of the face, arms, or legs, difficulty in communication, loss of consciousness etc. The loss of function in stroke is dependent on the number of neurons involved and how long the blood flow to the brain has been interrupted.
If one knee or hand has rheumatoid arthritis, usually the other does too. This disease often occurs in more than one joint and can affect any joint in the body. People with this disease may feel sick and tired, and they sometimes get fevers. Some people have this disease for only a few months or a year or two. Then it goes away without causing damage.
It is also common for those with this to have anxiety, weight loss, and an enlarged thyroid. Sex drive can be decreased with this and heart palpitations can be seen over time as the disease continues to affect one’s life. Not only can the body be affected in these ways but also the eyes and skin can be greatly affected and can cause the body to develop other conditions. The eyes specifically have been affected in many ways with Graves’. Vision loss, redness, pressure, sensitivity, and eye bulging are all symptoms of a Graves’ opthalmopathy case.
People experiencing vascular dementia will, like those with Alzheimer’s disease, have problems with learning, remembering, recognition, planning and problem solving. However, there is a major difference in the two diseases. Alzheimer’s disease tends to affect the whole of the brain and to progress gradually and steadily. Vascular dementia tends to affect only certain areas of the brain, and this means someone may retain more of their abilities – and also more awareness of their condition. Dementia syndrome or ‘mixed dementia’are terms for a condition in which abnormalities characteristic of more than one type of dementia occur simultaneously in the brain.
