An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically. A hemorrhagic stroke typically occurs when the blood vessel walls weaken over time, which leads to a bulge or rupture of the vessel. Aneurysm is the most common type of hemorrhagic strokes with a low survival rate. They also kill brain cells, which can never regenerate. The affect of strokes on the body can range between mild dizziness or slight numbness to impaired speech and loss of motor control.
INTRODUCTION Stroke or brain attack is the sudden loss of neurological function caused by an interruption of blood flow to the brain. Stroke is the third leading cause of death. There are two type of stroke commonly affected among people. A. Ischemic Stroke - Is the most common type affecting individuals - Lack of blood supply to the brain can be caused by thrombosis or embolism. It also may due to a hemorrhage.
Symptoms of strokes vary widely and are broadly grouped. It depends on the territory of the tissue affected. An occlusion of a cerebral vessel in the left hemisphere will cause right hemiplegia, aphasia, and dysphasia (Collins, 2007). They will often have impaired discrimination of their right and left extremity and exhibit slow cautious behavior. Patients with this type of stroke often suffer from depression.
It can lead to complications. Atrial fibrillation may lead to blood clots forming in the heart that may circulate to other organs and lead to blocked blood flow (ischemia)” The danger of this disorder is that the heart may not be able to pump enough blood to support the functioning of the body. There are some patients who will have some, all, or no symptoms at all. Some symptoms include: • “Palpitations, which are sensations of a racing, uncomfortable, irregular heartbeat or a flip-flopping in your chest • Weakness • Reduced ability to exercise • Fatigue • Lightheadedness • Dizziness • Confusion • Shortness of breath • Chest pain Atrial fibrillation may be: • Occasional. In this case it's called paroxysmal (par-ok-SIZ-mul) atrial fibrillation.
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.
In some cases gallstones may be removed to relieve blockage of the pancreatic duct. In the most severe cases, surgery is needed to remove dead or infected pancreatic tissue. Complications from acute pancreatitis include acute kidney failure, ARDS, ascites, Cysts or abscesses in the pancreas, and heart failure. Repeat episodes can lead to chronic pancreatitis.

Antibiotics are given before and after the procedure to avoid fetal infection. Amniocentesis is useful in diagnosing many genetic disorders before the baby is born. In families with genetic diseases or for a mother with previously born child affected by some genetic condition, the test is useful to confirm or to assess the risk of recurrence. Triple test is a test where markers in the blood are tested for Down syndrome, trisomy 18 and trisomy 13. This test does not confirm the diagnosis of these syndromes but tells us about the
* Pain when urinating * Constipation. There are many physical exams that can be use to check for vaginal cancer. A physical exam is a test of the body to check for health, diseases, and any cancerous lumps. These are some of the test: * Pelvic exam: An exam of the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum. The doctor or nurse inserts one or two lubricated, gloved fingers of one hand into the vagina and places the other hand over the lower abdomen to feel the size, shape, and position of the uterus and ovaries.
It is caused by nerve cells dying in certain areas of the brain and the connections between the affected nerve cells deteriorate. As the conditions affecting only or primarily the neurons of the brain, causes gradual but irreversible loss of functions of these cells, Memory loss is one of the earliest symptoms of this disease. Vascular dementia is caused by damage to the brain through deprivation of oxygenated blood causing part or all of the affected area to die. (Series of strokes) Conditions that can cause
Other risk factors includeanemia, blood transfusions, respiratory distress, breathing difficulties, and the overall health of the infant. There are five stages of Retinopathy of Prematurity ranging from mild to severe. In stage one, the disease is mild and usually is resolved on its own. Stage two is moderate and will also resolve on its own without treatment and will eventually develop normal vision. Stage three is severe, blood vessels grow towards the center of the eye instead of their normal growth pattern around the retina.
