Overview of Strokes

Unformatted Sample Text from the Research Paper:
30 days following a stroke is 30 percent (Duncan, 1994). The mortality rate for all stroke victims is between 20 and 25 percent (Alexander, 1997). The mortality rate is higher  for a hemorrhagic stroke than it is for ischemic stroke. This is the third leading cause of death in this country. Strokes can cause significant disabilities (Duncan, 1994). There are  two types of stroke: 1. Ischemic: An ischemic event that resolves within 24 hours is called a transient ischemic attack (TIA). Ischemic strokes account for 80-85% of all strokes with  thrombotic occlusion causing approximately 55% and embolic occlusions causing approximately 25% of ischemic stroke. In this type of stroke, there is a sudden onset of neurological dysfunction that clears with  no permanent damage. Statistically, about 25 percent of patients recover completely within 5 minutes; 50 percent in 30 minutes. If symptoms persist for longer than one hour, there is only  a 15 percent chance that neurological symptoms will disappear within 24 hours. The majority of TIAs are cardioembolic - caused by emboli that break loose from ulcerated atherosclerotic plaques 2.  Hemorrhagic: Hemorrhage is the cause of the remaining 15-20% of stroke and occurs most commonly due to ruptures in the bifurcation of small arteries within the brain. The most common  cause of hemorrhage into the brain is a significant increase in systolic/diastolic blood pressures over time and often occurs after mild exertion (Robertson, 2001). Many of stroke survivors will recover  at least a portion of the functions they lose. Stroke victims may develop weakness in their arms, they may have trouble walking, they may also suffer from vision problems, cognitive  disorders, depression and incontinence. Alexander notes that "The brain can recover to a certain extent and the milder the stroke, the better the recovery. Most improvements will occur within 8
