Alzheimer’s disease (AD) is a progressive and fatal form of dementia, frequently seen in the elderly altering their cognition, thought process and behavior. AD is reported in about half of patients that have a dementia diagnosis; one study states that about 10.3% of the population over 65 years is affected by dementia with an increase to almost 50% over the age of 85. (Beattie, 2002) Alzheimer’s disease is not a normal part of the aging process in humans, but rather found in a group of diseases that affect the brain leading to a decline in mental and physical control. AD when diagnosed has a very slow and gradual course, initially affecting the individual’s short term memory. (Beattie, 2002)
Alzheimer’s disease is the 6th leading cause of death, affecting more than five million people in the United States and is also one of the most common forms of dementia. Dementia can be defined as a disorder of progressive cognitive impairment severe enough to affect daily functions of an individual’s life. (Fillit et al, 2002)
Early 1900’s a man named Alois Alzheimer cared for a woman who had rapid severe declining dementia, after she died he was able to study her brain where he found atrophy of the grey matter along with plaques and neurofibrillary tangles, which when destroyed interrupts the messages sent from the neurotransmitters to the central and limbic regions of the brain resulting in early occurrence of memory impairment in an individual, the disease is already well established before symptoms are noticed in the individual. (Gaurthier, 2007)
Onset of symptoms can usually be seen by the age of 60, and may be gradual, and is categorized by stages from mild to severe, and may lead to a complete dependence by a caregiver. When a diagn...

Alzheimer’s disease affects populations in both cities and rural areas. Although only 19% of older adults live in rural areas, up to one-third of rural populations are comprised of older adults (Sun, Kosberg, Kaufman, & Leeper, 2010). In addition to limited access to and suspicion of healthcare and social services for older adults and their caregivers, social isolation plays a great role in rural areas, where opportunities for engagement and interaction may be unavailable or inaccessible (Sun et al., 2010). Healthcare workforce shortages, while present far and wide, are intensified in rural areas and can severely limit a family’s choices when caregivers struggle to meet the needs of individuals with Alzheimer’s (Sun et al., 2010). Research suggests a high level of depression in both persons with dementia and spousal caregivers in rural populations (Haley et al., 2008). Research also suggests the loss of language capacity among individuals with Alzheimer’s limits the individual’s independence.

Memory plays a significant role in the everyday lives of people of all ages. It allows them to recall information and remember skills that were learned in the past. Memory also organizes past information to help people make current and future decisions. However, imagine forgetting the names of close family members or not having the ability to find your keys every time you want to leave the house. These are some of the struggles that people with Alzheimer’s disease face daily. Alzheimer’s disease was first identified by German neurologist Alois Alzheimer in 1906, and was discovered to have an overpowering effect on explicit memory loss (Gruetzner, 1988). There are two types of Alzheimer’s disease – early onset and late onset. Early onset occurs in patients who are diagnosed before the age of 65 whereas late onset occurs in patients who are diagnosed after the age of 65. In the early stages of Alzheimer’s disease, short-term memory is often lost. As Alzheimer’s disease progresses, problems with long-term memory begin to develop, in addition to short-term memory impairments. Although a lot is known about the symptoms of Alzheimer’s disease, the cause has not been conclusively identified. However, as research continues, new theories about the cause of Alzheimer’s disease are being proposed. This has led to a controversy over whether Alzheimer’s disease is caused by genetics or environmental influences (Gruetzner, 1988).
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 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.
It is not uncommon for AD patients to become lost and wander away from their homes, thus leading to a very disturbing and upsetting experience for family members.
Alzheimer's disease is the most common form of dementia, and this terminal, progressive brain disorder has no known cause or cure. Its greatest known risk factor is increasing age which is why is it is infamous for developing in the elderly, typically in ages 65 or over, however for the 5%(1) that develop Alzheimer’s in their 40s or 50s it is known as early Alzheimer’s. Because Alzheimer’s worsens over time, those with it tend to struggle with completing daily tasks especially elderly people. Given that there is no cure for Alzheimer’s, the treatments available slow the worsening of dementia symptoms and improve quality of life for those with Alzheimer’s and their caregivers. It is not known what causes Alzheimer's, however, those with Alzheimer's have been found to have abnormal amounts of protein (amyloid plaques) and fibres.(The amyloid plaques and fibres are found in regions of the brain where problem solving and thinking take place e.g The cerebrum.) Due to the unusual amounts of amyloid plaques and fibres, it reduces the effectiveness of healthy neurons and eventually, destroying them.
Alzheimer’s disease (AD) is a progressive, terminal, degenerative brain disease. It is the fourth leading cause of death in adults and currently affects over four million people in the United States. This number is expected to increase over the next several years as the baby boomers age, until it reaches fourteen million by the year 2025.
Alzheimer’s disease comes from the last name of a neuro-psychiatrist from Germany, Alois Alzheimer. The disease was first diagnosed when a woman in her early fifties began experience memory problems. “Alzheimer recounted the now famous case of ‘Auguste D.’ a 51-year-old housewife who had been failing mentally for several years. As a result she had been admitted to his care in the Asylum for the Insane and Epileptic…” (Maurer and Maurer 1). After her death, he continued to examine her brain to find causes and explanations for her behavior. He discovered “…classic neuro-pathological signs of plaques and tangles” (Maurer and Maurer 1). “Plaques are chains of amino acids that are pieces of the amyloid precursor protein…tangles are aggregates of the protein tau” (Secko 1). As plaques develop they produce tangles and “these two abnormalities ultimately lead to loss of cognitive function” (Secko 1) Alois Alzheimer’s research has allowed many specialist to conclude that the apolipoproetein E gene may contribute to the disease.

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).
