In the times in which we live, there are many hundreds of institutions that are working on the Alzheimer’s issue. Researchers are hoping to break the mysteries of this disease and wipe it from the face of the earth forever. It is estimated that there are now more than 5.2 million people in the United States living with AD and as the population ages; this number is expected to triple by the year 2050. Among baby boomers aged 55 and over, one in eight will develop AD and one in six will develop a dementia. Half of all persons 85 years and older will develop the disease. Although the illness usually develops in people age 65 or older, it is estimated that over 500,000 people in their 30s, 40s, and 50s have Alzheimer 's disease or a related dementia. It is the sixth leading cause of death in the country. According to the California Department of Public Health,…

As more and more neurons die, regions of the brain that are affected begin to shrink. By the end stage of Alzheimer’s disease, brain tissue has shrank drastically and damage is widespread. (Huether & McCance, 2012) Epidemiology Late-onset AD, most common disease of aging AD is the most prevalent cause of dementia and accounts for over 50% of cases Symptoms of AD typically appear after the age of 65 Slowly Progressive disease that advances over a period of 5-10 years (McPhee & Hammer, 2012) Clinical Presentation Progressive mental deterioration Memory failure Mood changes …
AD strikes at the core of individuality by taking people’s ability to think for themselves. Memory loss is one key symptom of AD, but judgment, planning, calculation, and decision-making are also impaired and constantly worsen over two to twenty years and it has huge emotional impacts for patients and their families. Consequently, it is the quintessential condition of aging in terms of triggering need for all the financial and personal resources available, from family to physician to community resources to nursing…
Alzheimer's disease-Alzheimer's disease (AD) is a progressive, neurodegenerative disease characterized by memory loss, language deterioration, impaired ability to mentally manipulate visual information, poor judgment, confusion, restlessness, and mood swings.…
The effects of Alzheimer’s are directly brought upon by what happens to the brain. Brain cells are damaged and killed; the brain of an individual with the disease has many fewer cells than the average, functioning brain. Between the very few surviving cells, there are also many fewer connections. Due to this, the brain goes through severe shrinkage. This may be due to the plaques and tangles that form within the organ that disrupt proper cell to cell communication and inhibit the transport of essential nutrients and other materials. The effects of Alzheimer’s on the individual worsen over time as the brain deteriorates. According to Barry Reisberg, M.D., clinical director of the New York University School of Medicine 's Silberstein Aging and Dementia Research Center, Alzheimer’s can be split up into seven stages. In first stage of the disease, there are absolutely no symptoms and the person functions normally with no signs of dementia. This usually lasts up to eight years. Soon afterwards, the person experiences very mild cognitive decline in which he feels that he has…
Alzheimer's disease (AD) is classically defined as a dual clinicopathological entity. The cause of Alzheimer's disease is unknown. This gap in knowledge has created a stumbling block in the search for a genuinely effective treatment or cure for this dementia,…
Alzheimer's disease is one of the most common causes of dementia. The term 'dementia' describes a set of symptoms, which can include memory loss, changes in mood and problems with communication and reasoning. These symptoms occur when certain diseases and conditions, including Alzheimer’s disease, damage the brain. Alzheimer's disease could be described as a physical disease affecting the brain. During the course of the disease, protein 'plaques' and 'tangles' develop in the structure of the brain, leading to the death of brain cells. People with Alzheimer's may also have a shortage of some important chemicals in their brain. These chemicals are involved with the transmission of messages within the brain.…
Alzheimer’s disease is an irreversible, progressive brain disease that slowly destroys memory and thinking skills, and eventually even the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear after age 65. During the preclinical stage of Alzheimer’s disease, people are free of symptoms but toxic changes are taking place in the brain. Abnormal deposits of proteins form amyloid plaques and tau tangles throughout the brain, and once-healthy neurons begin to work less efficiently.…
In 1906, Dr. Alois Alzheimer was the first one to recognize the abnormality of a brain affected with Alzheimer’s. Alzheimer’s disease is a type of dementia that causes problems with memory, thinking and behavior. With Alzheimer’s the connections between the brain cells deteriorate and die, which causes the memory loss. There are many myths surrounding Alzheimer’s disease. “It is a normal part of aging” is one of the biggest. While some memory loss is expected with aging, Alzheimer’s is concerned with a severe amount of memory loss. The severity can limit a person’s ability to perform daily tasks. “Older people are the only ones who get it” is one that seems to go hand-in-hand with Alzheimer’s being a normal part of aging. While the majority of those who are diagnosed with Alzheimer’s are between the ages of 65-80, there are cases where early onset can be detected as early as ones 40s or 50s. Past treatments included treating some of the symptoms because there was no known cure. Medication to treat depression and memory loss were able to help some of the symptoms, but some had seen cognitive effects because of this.…

Alzheimer’s affects more than 5.1 million Americans and nearly as 44 million people worldwide. “Alzheimer's disease is a progressive, degenerative disorder that attacks the brain's nerve cells, or neurons, resulting in loss of memory, thinking and language skills, and behavioral changes,” (Alzheimer). Alzheimer’s is an illness that develops in individuals as they are aging and the number of cases of individuals developing Alzheimer’s have doubled in recent time. Alzheimer’s attacks the brain in ways the effects how a person lives their daily lives. It prevents people from being independent since it attacks the brain functions and causes them to become forgetful and confuse most of the time. During the early stages of Alzheimer’s individuals forget small things like where they placed something, and in later stages they…
Alzheimer’s disease, what is there to say about this disease? There is an uncomfortable ease about knowing that it is known that you develop this disease in old age, or do you. We will learn and understand about how (AD) Alzheimer’s disease was discovered, named, its’ myths, past and present treatments, signs and symptoms, and diagnosis. It will be known how it was considered a disease and not just a normal or regular part of becoming of age or aging. With Alzheimer’s having several stages associated with it, we will discover that not everyone will experience all stages, symptoms, or progress at the same time or rate.…
Alzheimer’s disease is an irreversible, progressive brain disease that slowly destroys memory and thinking skills, and eventually even the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear after age 60. Alzheimer’s disease is the most common cause of dementia among older people. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities, to such an extent that it interferes with a person’s daily life and activities. Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person’s functioning, to the most severe stage, when the person must depend completely on others for basic activities of daily living.…
* Early onset AD: Symptoms appear before age 60. This type is much less common than late onset. However, it tends to get worse quickly. Early onset disease can run in families. Several genes have been identified.…
