Alzheimers Disease
What is Alzheimers Disease? The most common form of dementing illness,
Alzheimers Disease (AD) is a progressive, degenerative disease that attacks the brain, causing impaired memory, thinking and behavior. The person with AD may experience confusion, personality and behavior changes, impaired judgment, and difficulty finding words, finishing thoughts or following directions. It eventually leaves its victims incapable of caring for themselves.
What happens to the brain in Alzheimers Disease? In AD The nerve cells in the part of the brain that controls memory, thinking, are damaged, interrupting the passage of messages between cells. The cells develop distinctive changes that are called neuritic plaques (clusters of degenerating nerve cell ends) and neurofibrillary tangles (masses of twisted filaments which accumulate in previously health nerve cells). The cortex (thinking center) of the brain shrinks (atrophies), The spaces in the center of the brain become enlarged, also reducing surface area in the brain.
What are the symptoms of Alzheimers Disease? Alzheimers Disease is a dementing illness which leads to loss of intellectual capacity. Symptoms usually occur in older adults (although people in their 40s and 5Os may also be affected) and include loss of language skills such as trouble finding words, problems with abstract thinking, poor or decreased judgment, disori...
Sherry Turkle, a dedicated author and well-known professor of Social Studies of Science and Technology, in her essay, “The Flight from Conversation,” implies that using technology for a majority of daily communication has become an significantly negative factor in society. Turkle supports this claim by revealing her own professional research on the topic along with descriptions from personal experiences. Her purpose is to help readers realize the abundant amounts of time that people waste on their devices for communication instead of choosing face to face sentimental contact. She disclosed a concerning tone for society’s decrease in social skills due to its obsessions with technology, for an audience who participates daily in using telecommunications. Turkle’s writing is implausibly effective, causing the readers to reevaluate the true importance of face to face contact and value personal communication.
Turkle takes a strong stance in opposition of technology, namely sociable robots, throughout her book, but her argument is significantly weakened
In this book Sherry Turkle studies something she thinks we as a people are losing sight of, which is face to face conversation. She explains in her book why she believes this is so important, and the consequences we will face if we continue to ignore this growing problem. Her argument about conversation stems from talking to people, face-to-face, In which she finds many of whom have difficulty doing so. Turkle Believes this is mainly because of digital technology. In today’s world people are so glued to their phones, that they loose grip on what it 's like to hold a conversation. Sherry understands this is to be because when we use digital technology as a form of communication, we only utilize one or two of our human senses.The
performance that involves, but is not limited to, a loss in at least 2 of the
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.
Sherry Turkle’s article in The New York Times “The Flight From Conversation”, she disputes that we need to put down the technology and rehabilitate our ability to converse with other human beings because we are replacing deep relationships with actual people for casual encounters on technology. Turkle tries to convince young and middle age individuals who are so enthralled by the technology that they are losing the ability to communicate in a public setting. Sherry Turkle unsuccessfully persuades her audience to put down the technology and engage with others in public through her strong logos appeal that overpowers her weak logos and doesn’t reliably represent herself and her research.
Alzheimer’s disease is a form of dementia which is a brain disorder that impairs mental functioning. Dementia attacks the part of the brain which controls memory, language, and thought. It makes everyday tasks like remembering to brushing your teeth, or to pay your bills next to impossible to do, which is why so many people who are diagnosed with this disease are in complete care. This disease has different phases, the first being slight forgetfulness and then the persons emotions may heighten as well as language impairment, violent outbursts, loss of bladder control and from there it keeps getting worse until complete dysfunction of the brain occurs and eventually death, which most of the time is the result of infection.
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.
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 ...
Returning to the quotation “… the great leveler, Death: not even the gods/ can defend a man, not even one they love, that day/ when fate takes hold and lays him out at last’” (Homer 3.269-271). Death is a power that surpasses the gods. In The Odyssey we are introduced to gods who control the water, the wind, and the decisions of men. They can bring peace and war, but the one thing they cannot do is prevent a mortal’s fated death. This alone shows how central death is to The Odyssey. The power that death holds rivals no others in this story, there is “… no escape from death” (Homer 12.483). Death is a constant threat for Odysseus throughout this story, and the future foretold for Odysseus by Tiresias is not one of his life being a good one but of “…your own death will steal upon you…/ a gentle, painless death, far from the sea it comes to take you down…” (Homer 11.153-154). His fortune ends not with his happy life, but with his eventual death. This scene is crucial because it draws the reader back not to the life that Odysseus will have once he has successfully returned home and killed the suitors but the death that he will experience. It draws it back to when and where Odysseus will die and take his place among the
Turkle’s stance on this topic is emotionally engaging as she uses rhetoric in a very powerful approach, while also remaining unbiased. The article flows very smoothly in a beautifully structured format. The author maintains a composition that would appeal to the interest of any sort of audience. She effectively questions the reader’s views on the negative consequences technology has on social interactions. Her work is inspiring, it sheds light on the dark hole society has dug for themselves, a state of isolation through communication in the digital age; this is a wake up
Diffusion and osmosis refer to passive transport systems where molecules and ions move down concentration gradients driven by thermal motion. The concentration gradients are setup in solutions in living systems that are separated by biological membranes. Diffusion refers to the spontaneous movement of particles, molecules, or ions from an area of higher concentration to an area of lower concentration. The process occurs slowly without any expenditure of energy. Diffusion occurs in liquids and gases. An example of diffusion is the movement of the smell of a spray from the point of spraying to the rest of the room. On the other hand, osmosis refers to the movement of molecules of a solvent such as water from an area of low concentration to an area of higher concentration. It is a special type of diffusion that occurs in reverse. An example of osmosis is the process through which animal cells feed on the food they partake. Thus, diffusion and osmosis are called passive transport systems because they enable cells of living systems to move molecules in
In this analysis, I will be focusing on “The Flight from Conversation” which is an article by Sherry Turkle and exemplifies her view on the constant progressing technological universe in which we spend a hefty amount of our sacred time in. Turkle provides many examples in her work that show how devices and technology are taking over our lives, and are taking away our ability to communicate face to face easily and effectively. She does a great job portraying her reasonings on how we are getting lost in technology, such as, on our phones at the dinner table, work, or whenever we feel uncomfortable, putting headphones in to avoid interaction, and wanting comfort from robots. We have been brainwashed and it’s only getting worse.
In Sherry Turkle’s article “The Flight from Conversation,” she emphasizes that technology has given us the chance to be comfortable with not having any real-life connections and allowing our devices to change society’s interactions with each other. Turkle believes that our devices have allowed us to be comfortable with being alone together and neglecting real life connections. She opens her article up with “We live in a technological universe in which we are always communicating. And yet we have sacrificed conversation for mere connection.” (Turkle, 2012. Page 1). Turkle is trying to say that we have given up on socializing with each face-to-face and forgot all about connections. In the article, Turkle continues to provide examples of how we let our devices take over and
Odysseus was an extraordinary man. He was blessed with the favor of the Greek gods, and had a brilliant mind which was shown time and time again throughout the narrative. Early Greek culture placed heavy emphasis on war, and the wealth and power that would come from winning a battle. From these battles arose epic war heroes who surpassed all obstacles in order to defeat their enemies. Odysseus joined with the ranks of the war heroes during the Trojan War, when his brilliance led him to the idea of gifting the Trojans with a gigantic wooden horse with men hidden inside in order to divert the Trojan soldiers from realizing they were being attacked. It was Odysseus himself that led his men to victory and saved them from perishing. Odysseus was also shown to be an extraordinary man by being a mortal who was allowed to travel to and from Hades, where he saw and spoke to his deceased mother, friends, and other war heroes. It was in Hades where he learned that every man will die no matter how great and that stupidity alone can lead to any person’s demise. When Odysseus returned from the gates of hell he spoke to his men about what he had seen. As he spoke his men were “held by the spell of his words [and] they remained silent and still” (148) because Odysseus was given insight into death that was a mystery to every mortal man. Consequently, his godly favor and brilliance were both causes for his
