Reversing Stroke and Spinal Cord Damage :: Biology Essays Research Papers

Reversing Stroke and spinal anesthesia Cord DamageScientists ar on the brink of doing the unthinkable-replenishing the brains of great deal who project suffered jibes or head injuries to make them whole again. If that is not astonishing enough, they think they whitethorn be able to reverse paralysis. The door is at go away open to lifting the terrifying sentence these disorders still decree-loss of physical function, cognitive skills, memory, and personality.Until recently there was near nothing doctors could do for the 500,000 Americans who have strokes each year, the 500,000 to 750,000 who experience knockout head injury, or the 10,000 people who argon paralyzed after spinal cord vilify (3). However, that is about to change. Researchers now think it may be viable to replace destroyed brain cells with unexampled ones to give victims of stroke and brain injury a chance to relearn how to control their body, form young cerebration processes, and regain emotions. After dem olishing the long-standing myth that brain cells cannot regenerate or proliferate, scientists are develop ways to stimulate cells to do just that. Although stroke, head injury, and paralysis are three of the most devastating things that can happen to anyone, scientists have recently wise to(p) that the damage they cause is not preordained. It takes place over minutes, hours, and days, great(p) them a precious opportunity to develop treatments to halt much of the damage. Most of the new remedies are not yet available, but an explosion of research in the last five to ten years has convinced scientists that or so of them will work (8). channelise by fabulous results in preventing permanent damage from stroke and other injuries to the central nervous system in rats and other animals, researchers around the world have launched scores of trials in humans (12). However, many promising new therapies are sitting on the shelf because of a lack of money and other resources incumbent to co nduct large, lengthy, and expensive studies to conclusively show that a new drug or treatment really works in people. The requirement for safety and strength can be frustrating, especially for badly needed treatments that are very promising, but such caution is necessary.One organization is trying to raise currency for a major study to test a lozenge for paralysis-4 amino pyridine (4 AP) -which has shown promising results in preliminary human trials (14). About half of the small be of people in the study, who had been paralyzed for four to fifteen years, regained some sensation and muscle function when they were given intravenous infusions of 4 AP.Reversing Stroke and Spinal Cord Damage Biology Essays Research PapersReversing Stroke and Spinal Cord DamageScientists are on the brink of doing the unthinkable-replenishing the brains of people who have suffered strokes or head injuries to make them whole again.
