Alzheimer's Disease Case Study

Great Essays
Alzheimer’s presents changes in the brain referred to as neuritic plaques and neurofibrillary tangles. The neuritic plaques are formed when amyloid precursor proteins are not processed, resulting in toxic amyloid beta proteins, forming to make plaques. Neurofibrillary tangles are formed from the tau protein, a microtubule-binding protein, detaching from neurons to form tangles. Both plaques and tangles contribute to the death of neurons, resulting in the hallmark features of Alzheimer’s disease (McCance & Huether, 2014). These plaques and tangles begin in the entorhinal cortex, and exhibit some of the initial signs of Alzheimer’s disease. The entorhinal cortex is part of the temporal lobe and is involved in memory and the connection of …show more content…
It is as this time a cerebral biopsy can confirm the pathological processes of Alzheimer’s disease with the observation of plaques, tangles, and brain atrophy. The clinical assessments completed in patient history, ongoing change in symptoms, cognitive testing, diagnostic laboratory rule-out, and the patients qualifying for Amyloid PET imagining, are simply a diagnosis from clinical findings (McCance & Huether, 2013).
Genetic Contributions
Alzheimer 's Dementia has two classifications: early-onset or late-onset type. Researchers have not identified genes that contribute to late-onset Alzheimer 's Dementia (National Institute on Aging [NIA], 2014). While researchers believe that extrinsic factors such as lifestyle and environment are driving forces in late-onset Alzheimer 's, research uncovered that early-onset Alzheimer 's is primarily genetic in nature (NIA, 2014).

Cholinesterase inhibitors are used to treat mild to moderate disease. Medications used to block glutamine receptors are used for moderate to severe disease. Medications that block glutamine work to block glutamine receptors, specifically noncompetitive N-methyl-D-asparate (NMDA) receptors (McCance & Huether, 2014). A popular drug on the market is Namenda. Namenda is an NMDA receptor antagonist (Frandsen & Pennington, 2014). According to Frandsen and Pennington persistent activation of NMDA receptors increases effects of Alzheimer 's Dementia

    Dementia is diagnosed by the presence of symptoms such as problems with memory, thinking, problem solving, language disturbances and psychological changes. Neurodegenerative changes within the brain, such as neuron death and a build-up of misplaced proteins are causal to the aforementioned symptoms. While an in depth understanding of the neurobiology of dementia has not been established, dementia diseases are characterized by the grade of neuron loss and the irreversible damage within the connections of the brain, combined with the resulting symptoms (Caberlotto and Nguyen, 2014). One of the most common forms of dementia, Alzheimer’s disease, occurs as a result of chemical and degenerative structural changes within the brain. Dementia can also be caused by a number of conditions such as vascular dementia following a stroke, fronto-temporal dementia caused by brain injury or Korsakoff’s syndrome, which is associated with long term excessive drinking.…

    1. Dementia of the Alzheimer type (DAT) is an ongoing acute neurodegenerative sickness described by declining in intellect and memory, continuing damage in the power to perform day to day activities. DAT is the largest characteristic of dementia amongst seniors and makes up roughly two-thirds of events of dementia and linking sixty and seventy percentile of cases of progressive cognitive impairment in older adults. The occurrence of DAT is likely to increase as the people grow old. When it comes to diagnosing DAT, there are not any conclusive model or assessments, excluding brain biopsy, for diagnosis.…

    Late onset Alzheimer’s disease (LOAD) is the most common neurodegenerative disorder characterized by progressive loss of cognitive function that interferes with daily activities [38](Holtzman et al., 2011). The neuropathology involves neurofibrillary tangles, composed of hyperphosphorylated tau proteins, and β-amyloid (Aβ) plaques which obstruct proper synapse function and lead to neuronal cell loss and atrophy [5](Ballard et al., 2011). The most crucial risk factor is age; the risk doubles every five years after the age of 65, with higher prevalence in females than males [5;37](Hirtz et al., 2007;Ballard et al., 2011). There is also a strong genetic component that indicates increased risk of dementia in individuals expressing the E4 isoform…

    Several risk factors increase the likelihood of developing Alzheimer’s including minor, undetected strokes, infection from a virus, an injury to the head; a bad fall, or a car accident, and lastly lifestyle factors such as smoking and poor nutrition (Izenberg, 2000). A minor stroke cuts off blood supply to parts of the brain which causes cells to die, and this results in fibers and tangles of dead nerve cells to develop (Izenberg, 2000; MacGill). Infection from a virus might cause damage in the brain (Izenberg, 2000). An injury to the head might trigger damage in the brain in people who have certain genes linked to Alzheimer’s (Izenberg, 2000). Smoking and poor nutrition might also trigger the aging process to move faster (Izenberg, 2000; Smith…

    Although Alzheimer’s disease is mainly seen in the elderly, it can also be seen in 1-10% of people in there 30’s. Alzheimer’s is considered to be a progressive, degenerative disorder of the cerebral cortex. It is known to interfere with cognitive and behavioral impairment that causes social and occupational functioning. The cortical degeneration is marked in the frontal lobes, but the atrophy occurs in all areas of the cortex. The cause of Alzheimer’s is still unknown, but there is factor’s that contribute to this disease, such as neurochemical factors, which include deficiencies in the neurotransmitters, acetylcholine, somatostatin, substance p and norepinephrine (“Pathophysiology made incredibly visual!”…

    There are many guidelines designed to help researchers to organize clinical trials, studies in general, tests and even to help the physicians to plan an experimental treatment strategy. The newest guidelines describe Alzheimer’s as a progressive disease classified into stages: 1) the asymptomatic, preclinical stage (research only), 2) mild cognitive impairment and 3) dementia (end stage disease) (Souslova, Tatiana et al). One of the major challenges is to understand clearly the disease pathophysiology.…

    “When doctors examine Alzheimer 's brain tissue under the microscope, they see two types of abnormalities: plaques and tangles. Plaques are clumps of a protein called beta-amyloid may damage and destroy brain cells in several ways, including interfering with cell-to-cell communication. Tangles occur because brain cells depend on an internal support and transport system to carry nutrients and other essential materials throughout their long extensions. This system requires the normal structure and functioning of a protein called tau” (Mayo Clinic Staff).…

    Background Alzheimer’s Disease (AD) is a neurodegenerative disease and is the leading cause of dementia in late adult life. In 2015, 5.3 million Americans were diagnosed with AD, 5.1 million of whom were above the age of 65. AD is characterized by a progressive loss of cognitive function, and is associated with the accumulation of amyloid-B (AB) protein and hyperphosphorylated tau in the brain. Although the exact pathogenesis of AD is still uncertain, several hypotheses have been proposed to explain the mechanisms behind the cognitive deficits that are seen in AD. The amyloid cascade hypothesis, which asserts that amyloid precursor protein (APP) proteolysis results in the accumulation of AB peptides that aggregate to form extracellular plaques,…

    It processed that the mutations in the genes encoding Amyloid Precursor Protein (APP), Presenilin I (PSI) and Presenilin II (PSII) which are linked to AD suggested that Aβ peptide is the major initiator of the development of AD. It stated that the deposition of β-amyloid (Aβ) was the initial pathological event in Alzheimer’s disease resulting to the formation of neurofibrillary tangles (NFTs) and senile plaques (SPs), neuronal cell death and ultimately dementia (Maloney, 2015). Scientists assessed this hypothesis in 1989 by expressing the Aβ peptide in a cell line called PC-12cells that could be stimulated to differentiate to neurons when cultivated in the presence of nerve growth factor (NGF) (Yankner et al. 1989). The researchers found that the PC-12 cells grew normally while expressing the Aβ peptide, up until they were treated with nerve growth factor and stimulated to differentiate into neurons, at which time they began to degenerate and die.…

    The neurodegenerative diseases, or dementias, are characterized by progressive and irreversible degeneration of the neurons from specific regions of the brain. The pattern of neuronal loss is selective and compromises one or more groups of neurons, without affecting the others. An interesting aspect of these dementias is them arise without any apparent triggering stimulus and in patients with no history of neurological deficits. Alzheimer’s disease is the most prominent of these dementias, accounting for 60-80% of total dementia cases worldwide.…

    These include amyloid plaques, neurofibrillary tangles and the loss of connections between the neurons responsible for memory and learning abilities (“NINDS”). In those with Alzheimer’s amyloid plaques interfere with the communication between different cells which damages and destroys brain cells. In a brain affected by neurofibrillary tangles, failure of the transport system occurs when threads of tau protein twist into abnormal tangles inside brain cells (“Alzheimer’s disease”). In the more advanced stages of Alzheimer’s, the brain shrinks in size. The shrinking of the cortex, causes damage to functions such as thinking, planning and remembering.…

    Individuals with this disease show two different types of abnormal lesions that aren’t seen in normal brains. The beta-amyloid plaques, which are lumps of protein and other cellular material that form in and around the neurons, and neurofibrillary tangles, which are insoluble fibers made up mostly of the protein tau that build up inside nerve cells, both of these lesions will clog the brain; however physicians and scientists are unsure whether these lesions actually cause the disease, or if the lesions are a side effect of the disease.

    The cause or causes of Alzheimer’s diseases are not yet known. However, most experts agree that Alzheimer’s, like other common chronic diseases, develops as a result of multiple factors rather than a single cause. These factors include a variety of brain changes that begin as many as 20 years before symptoms appear. Increasingly, the time between the initial brain changes of Alzheimer’s and the symptoms of advanced Alzheimer’s is considered by scientists to represent the “continuum” of Alzheimer’s. At the start of the continuum, the individual is able to function normally even though there are changes in the brain.…
