Alzheimer’s disease Holly Salyards Cincinnati State Technical & Community College Alzheimer’s disease is a progressive brain disease which slowly destroys thinking and memory skills. These changes are severe enough to interfere with day to day life. This irreversible disease is the most common cause of dementia amongst the elderly, with an appearance of first symptoms after age 60. In 1906, Dr. Alois Alzheimer, noticed some changes in the brain tissue of a woman who had died of an unusual mental illness. Her symptoms were comprised of memory loss, language problems, and unpredictable behavior. After her death, Dr. Alzheimer examined her brain and found many abnormal clumps (amyloid plaques) and tangled bundles of fibers (neurofibrillary tangles). The aforementioned plaques and tangles in the brain are considered two of the primary features of Alzheimer’s disease. The third feature is the loss of connections between nerve cells or neurons in the brain. There is currently no cure for this traumatic disease, but current Alzheimer’s disease medications and management strategies may temporarily improve symptoms. This can sometimes help people with Alzheimer’s disease maximize function and maintain independence. There is still no known fact on how the Alzheimer’s disease process begins. They seem to think that the damage to the brain starts a decade or more before problems become evident. During the preclinical stage of Alzheimer’s disease, people are asymptomatic, but unfortunately there are toxic changes taking place in the brain. Abnormal deposits of proteins form amyloid plaques and tau tangles throughout the brain, causing the once-healthy neurons to work less efficiently. Over time, neurons lose the ... ... middle of paper ... ...ww.alz.org/alzheimers_disease_4719.asp (n.d.). Retrieved from http://www.nia.nih.gov/alzheimers/topics/causes (n.d.).

Alzheimer is a dementia type of disease named after Dr. Alois alzheimer that slowly destroys memory and thinking skills,and eventually , the ability to do simple things, or recognize their family. The first case occurred in the 1906 when a woman died on a unusual mental illness. After she died Dr.Alois examined her brain , amyloid plaques and neurofibrillary. Alzheimer’s is in older people the most common cause of dementia. Dementia is a loss of remembering ,thinking and reasoning skills, that intervenes with your daily life and activities. It is very common in people over sixty years of age. People younger than sixty years can also
Thesis/Preview Statement – Alzheimer’s disease (AD) causes a decline in brain function, it destroys healthy nerve cells. Today, we have discussed Causes, Symptoms, and Diagnosis of AD.
Clinically, Alzheimer’s disease is characterized by the accumulation of beta-amyloid plaque between living neurons in the brain (Sabbagh, 2008). This results in an excessive calcium influx inside the neurons and the breakdown of a protein called tau. Normally, the rol...
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 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.
The first case of dementia was discovered in 1906 by a German physiatrist Alois Alzheimer. It was first observed in a female patient and she was forty-one years old her name was Auguste D. Dr. Alzheimer observed a decline in the patient’s cognitive abilities. She lost her memory, she exhibited behavioral issues, and she suffered from hallucinations, lost the ability to comprehend language, disorientation and lost her speech. After Augusta’s passing Dr. Alzheimer preformed an autopsy that showed the classic triangles and knots we associate today with Alzheimer. Those triangles and knots are a proteins and plaque. The brain is self looked smaller and had distinct characteristics. Still with modern medicine the only way to diagnose a person with Alzheimer is after their death with an autopsy. (THE ALZHEIMER'S PROJECT, 2014).
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 ...
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.
degeneration 3 A nerve cell has numerous axons and dendrites coming out of it. A neurofibrillary tangle is when the neuron changes. A number of dendrites are missing and the nucleus is filled with protein filaments resembling steel wool. Although all elderly people have a few of these helix shaped bundles in their brain as they are normal indicators of aging, Alzheimer's patients have. more than usual.
In the field of Psychology you can find an abundance of mental disorders that can have an affect on people all throughout the world. Out of all the mental disorders that can be found around the world, some of them are more well-known and more widespread than others. The following disorders could be described as being well-known and widespread disorders: depression, bi-polar disorder, Alzheimer's, and OCD, which could also be called Obsessive Compulsive Disorder. All of these mental disorders can be very dangerous and possibly deadly if people don't receive the proper care in order to be able to contain these disorders. Out of these very dangerous and possibly deadly disorders, I believe that Alzheimer's is the most interesting disorder. I think that Alzheimer's is the most interesting disorder, because I think we have the least about of knowledge of the Alzheimer's disorder. As a society we still to this day don't have a cure that totally stops this disorder.
What is Alzheimer's Disease? Alzheimer's Disease is an existential form of Dementia. Alzheimer's is a gradually crippling disease that affects an individual’s mental and physical capabilities over time. The disease develops predominantly within aged individuals. It is unknown as to what factors contribute to the etiology, or cause, of Alzheimer's Disease. In order to better understand Alzheimer's Disease, medical research and theories have helped shed a light as to how Alzheimer's occurs. By understanding what events lead to the cause of the disease, a specific treatment can then be developed that can hopefully stop or even reverse this debilitating disease that affects the elderly.
In 1906, a German physician named Dr. Alois Alzheimer dealt with a patient that had been battling severe memory and confusion problems and had tremendous difficulty understanding questions and basic functions. Alzheimer suspected that the ailment had more to it than inherent memory loss. During an autopsy of the brain, he discovered that there were deposits of neuritic plaques surrounding the nerve cells and twisted fibers, known as neurofibrillary tangles, inside of the nerve cells. These observations became the definitive diagnosis of Alzheimer’s disease. The plaques and tangles that develop are a natural part of aging; however, they develop far more aggressively in Alzheimer’s victims. The plaques and tangles then block communication among nerve cells and disrupt the cells processes, eventually killing them. This destruction causes memory failure, personality changes, and problems carrying out everyday functions. Alzheimer’s especially attacks the memory. A victim in the later stage of the disease can...
A myth about Alzheimer disease says that nothing can be done about the disease. This is not true. Much can be done to assist the person with Alzheimer’s disease to maintain the highest possible level of functioning as long as possible and in providing the highest quality of life.
Since ancient times, it has been clear that some people lose mental sharpness (cognitive function) as they age. However, in 1906, the German neurologist Alois Alzheimer began an autopsy of a woman from Frankfurt, that had died after several years of progressive mental deterioration. From the accounts of the doctor, family, and friends of the woman, Alzheimer put together her mental state prior to death, and described the woman as being marked by increased confusion, disorientation, and memory loss.Taking advantage of staining techniques that had recently been established, Alzheimer noticed an odd disorganization of the nerve cells in the womanís cerebral cortex, the part of the brain...
Scientist have misunderstood this conditions for years, but they now believe the proteins that is a guarantee of Alzheimer disease may play a role in fighting infection. Although there is no way to cure Alzheimer’s there is medication to help slow the process of the memory loss. Medication include Aricept, Exelon, and Namenda, these are cholinesterase inhibitors. These drugs work by reducing the rate at which acetylcholine, a key neurotransmitter, is broken down, thereby increasing its concentration in the brain and offsetting loss of the substance caused by death of the neurons, known as brain
