Stephen Hawking is a theoretical physicist who is considered to be one of the greatest scientists alive today. At the University of Cambridge, he is the director of research in the Centre for Theoretical Cosmology. On January 8th, 1942, Stephen Hawking was born in Oxford, England. His parents were Frank and Isobel Hawking. At both of the schools he went to, St. Alban’s School and Oxford University, he was a sub-par student. Hawking suffers from Lou Gehrig’s disease. Lou Gehrig’s disease is a disease that attacks the spinal cord and the brain. This made him be in a wheelchair for life. When Hawking was twenty one, he was diagnosed with Motor Neurone Disease, a disease where nerves cells in the body die. He married Jane Hawking in 1965, and
Imagine if you loss control of your body but your mind stayed unaffected. You would be a prisoner in your own body, all leading up to your death sentence. That is the sad fate for the people diagnosed with Amyotrophic lateral sclerosis (ALS). “Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder was first described by Ran in 1850. This description was then expanded in 1873 by Charcot, who emphasized the involvement of the corticospinal tracts. In the United States, ALS is often referred to as Lou Gehrig's disease, after the famous ball player who was stricken by the disease in the midst of his career. (Yale School of Medicine, 2014)” In this paper will go through the definition, the process, the signs, the risk factors, etiology, and discus the known people that have suffered with this terminal disease.
Lou Gehrig's disease is often referred to as Amyotrophic lateral sclerosis (ALS), this is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons come from the brain to the spinal cord and from the spinal cord to the muscles throughout the entire body. The progressive degeneration of the motor neurons in ALS would eventually leads to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is also lost. With voluntary muscle action progressively affected, for this reason patients in the later stages of the disease may become totally paralyzed (Choi, 1988).
Hawking is still alive and has been living with his disease for fifty-two years now (“Stephen Hawking Biography”, n.d.). In doing research as to how Hawking has been able to live so long with this disease, I came to the conclusion that there is not a reason. An article written by Terrence McCoy (2015) in the Washington Post described his lengthy life as “extraordinary” and “extremely rare”. This is further indication that his interminable existence is supported by pure luck. What an incredible coincidence that such an important man was able to withstand the consequences of a highly fatal disease. Stephen Hawking, the Hawking family, and the rest of the world are, whether they know it or not, thankful for this one man’s extreme luck. His contributions to scientific knowledge and his perseverance will be forever
ALS or Lou Gehrig’s disease attacks the muscles of the body. Typically, symptoms don’t usually begin until the age of 50 or older. However, it’s possible to show symptoms at a younger age. It is a disease that progresses extremely fast. Unfortunately as the disease progresses, loss of muscle strength get worse. The reduction of the muscle strength slowly gets worse until paralysis or death. The following are symptoms of ALS: muscle cramps, muscle weakness, difficulty with breathing and difficulty with swallowing. Other symptoms include slurring of words, hoarseness, and weight loss. ALS does not affect the five senses of the body. Eventually, Lou Gehrig’s Disease will prevent the body from doing everyday activities such as driving, climbing stairs, and eating.
performance that involves, but is not limited to, a loss in at least 2 of the
Alzheimer’s disease, named after Dr. Alois Alzheimer, is a disease that is on the rise in America and the rest of the world. People should learn as much as they want about this disease, because as you age, your chances of becoming an Alzheimer’s Disease, or AD, patient increases. It is estimated that approximately 3 percent of Americans between the ages of 65 and 74 have the illness, and more than half of all people over age 85 have the ailment.
A piece of well-oiled machinery consists of an intricate and complex system: there are well-organized processes, mechanisms within the device work efficiently, and multiple processes function simultaneously to subsequently perform various functions. What happens when there is a glitch in the machine? When there is something wrong, such as connections between intricate processes, which do not follow through, the machine fails to function properly. In some cases, there are not any adjustment or fallback mechanisms. At that point, the damage can be irreversible and the machinery is no longer salvageable. [However, this can illustrate the interactions and processes within the complex machinery.]
Alzheimer’s disease is a complex illness that affects the brain tissue directly and undergoes gradual memory and behavioral changes which makes it difficult to diagnose. It is known to be the most common form of dementia and is irreversible. Over four million older Americans have Alzheimer’s, and that number is expected to triple in the next twenty years as more people live into their eighties and nineties. (Johnson, 1989). There is still no cure for Alzheimer’s but throughout the past few years a lot of progress has been made.
Alzheimer’s disease or AD is an incurable disorder of the brain that results in loss of normal brain structure and function. In an AD brain, normal brain tissue is slowly replaced by structures called plaques and neurofibrillary tangles. The plaques represent a naturally occurring sticky protein called beta amyloid and in an Alzheimer’s brain, sufferer’s tend to accumulate too much of this protein. Neurofibrillary tangles represent collapsed tau proteins which, in a normal brain along with microtubules, form a skeleton that maintains the shape of the nerve cells. In Alzheimer’s disease, the tau proteins break loose from their normal location and form tangles. Without the support of these molecules, nerve cells collapse and die. As normal brain structure is lost with progression of the disease, brain function also degenerates. Patients afflicted with Alzheimer’s disease display a gradual mental decline. Initially, and most apparently, there is a loss of short-term memory. Eventually, as a patient progresses to later stages of the disease, the brain becomes so damaged that patients can no longer communicate or recognize immediate family or even themselves. They have difficulty walking and standing and frequently fall. In the final stages, they lose bladder and bowel control and have difficulty with swallowing, frequently leaving them malnourished and dehydrated. Eventually, they are forced to remain bedridden and, without the help of life-prolonging measures provided in a hospital, die. However, this level of deterioration is severe and may take as long as twenty years. Because of the disease’s slow progress and its usual later start in a person’s life, a victim of AD will usually die first of natural causes. Under the objectives ...
Stephen Edwin King was born on September 21, 1947 at the Maine General Hospital in Portland, Maine. His parents were Donald Edwin King and Ruth Pillsbury King. Stephen being the only natural born child in the family and his older brother David having been adopted at birth two years earlier.
In this day and age, it seems as though almost everyone has experience a loved one taken away form a very serious disease known as Alzheimer’s disease. Alzheimer’s disease is unbelievably devastating for everyone affected by it. This disease is causing major economical problems such as less occupancy in the nursing homes, and hospitals due to the rising population of elderly men and women being diagnosed with it everyday. Because there is not yet a cure for this disease and the percent of the population being diagnosed keeps rapidly rising, more time and money needs to go towards Alzheimer’s research.
Alzheimer's Disease Introduction to Alzheimer's Alzheimer's disease is a progressive, degenerative disease of the brain. It was first described by the German neuropathologist Alois Alzheimer (1864-1915). in 1905. This disease worsens with advancing age, although there is no evidence. that it is caused by the aging process.
Steve Jobs was born on Feburary 24, 1995 in Green Bay Wisconsin. His biological mother put him up for adaptation, because she could not care for him and give him a good child hood. She requested that her son to be placed with a well-educated family. When Steve Jobs was growing up he Didn’t have any friends so he wandered to neighbors garages looking to learn more about electronics because a lot of them were engineers. Steve jobs liked fiddling with electronics so much that he spent his time after school at the packyard electronics company learning more in depth about how to make electronic devices. Steve jobs had a hard time focusing in class. Until his fourth grade teacher found a way to get him to focus in class it was by bribing him to do his work. That worked so well that the school recommended him to skip fifth grade and go straight to junior high. Steve jobs told his parents he did not like the school that he was going to, and wanted to change schools. Steve Jobs and his parents moved to silicon valley where there was a premiere school for electronics and technology. He found a friend when he was in high school that was a geek just like him, that friend was Stephen Woznick. Stephen Woznic...
Stephen Hawking has been hailed as one of the most brilliant theoretical physicists since Albert Einstein. Hawking was born on January 8, 1942, which as he likes to point out is the 300th anniversary of Galileo's death. Hawking originally studied at Oxford University in England studying physics even though he would have preferred math. He moved onto Cambridge University to work on his PhD in cosmology. Hawking's career has focused upon the cosmic entities known as black holes, and has extended to specialized areas such as quantum gravity, particle physics, and supersymmetry.
...research about black holes and explaining radiation. Stephen was awarded couple of awards such as Prestigious Albert Einstein Award, Pius XI Gold Medal for Science, and became member of the Royal Society. Soon after Hawking condition was at a point where he couldn’t talk. He then developed a speaking program for his illness. (biography.com) With the help of his computer base commutation system, Stephen was able to interact with others inspite of his disability. Some features of the technology included a keyboard,webcam and speech sinre. To operate the machine he would use his cheek muscle. ( Hawking.org)
