Alzheimer's Disease Pathophysiology

Superior Essays
Since Alzheimer’s disease (AD) was discovered, victims of the disease, family members, and physicians became curious to know more about this now well-known illness. It has inspired many to conduct research to better understand the disease, so this research sets out to examine the pathophysiology of AD. Through this research, the disease was found to be defined as a category of dementia and is analyzed in depth through the understanding of the causes of the disease and how it affects the human body, considering the effects brought upon the brain and what results from them. How an individual is diagnosed with AD is also analyzed along with the treatments that patients may consider once diagnosed. To understand how this disease affects the …show more content…
It affects the Central Nervous System (CNS) and causes it to slowly affect the rest of the organ systems ("Alzheimer 's Disease Fact Sheet | National Institute on Aging” 3). In mild Alzheimer’s, one of the first two regions of the brain to be affected is the Entorhinal Cortex (EC) which holds the understanding of long-term memory (Puthiyedth et al. 4). Therefore, when it is damaged by Alzheimer 's, patients experience a larger amount of memory loss. The second region to be affected is the Hippocampus (HIP) located in the temporal lobe of the brain (Puthiyedth et al. 4). When the HIP is damaged patients with Alzheimer 's will slowly stop forming new memories. The HIP and a lipid transporter work together to damage blood flow which leads to the lack of oxygen to the brain (Puthiyedth, et al. …show more content…
293). Through questioning, MacRae reached the conclusion that the participants knew who they were in a sense of “informal roles, attributes, actions, and qualities” and believed they were the same person they were before the disease affected their lives but without some cognitive abilities they previously had (Macrae, 2009, p. 296). MacRae’s research led to finding what exactly assists individuals affected by AD in maintaining their identity. Normalizing, living in the present, altering aspirations and reappraising priorities, social comparison, the life review, and constructing self have proven to be aspects in MacRae’s study which helped the participants maintain their sense of identity while living with AD (Macrae, 2009, p. 298-300). The study also revealed that the relationships and communication the participants had with other individuals contributed to their feelings toward their identity and their overall ability to “manage identity [depending] on the support and cooperation of others” (Macrae, 2009, p. 301). A positive environment led to more positive behavior and a positive view towards themselves, while a negative environment would do the

    [1] Alzheimer’s is a mental deterioration disorder, which commonly occurs in middle or old age. This is caused because of generalized degeneration of the brain. Alzheimer’s affects the brain due to the presence of abnormally structured neurons, which reduce the amount of acetylcholine in the brain. What this means is that the brain is slowly losing its ability to retain information, as well as, erasing everything learned over time. [2] Scientists know genes are involved in Alzheimer’s; much like hair and eye color, diseases can be passed from parent to child.…

    The inability to remember basic things and retain new information are the first symptoms in three out of every four cases. Neuronal damage eventually affects parts of the brain that enable a person to carry out basic bodily functions such as walking and swallowing (Alz). In the case of Alzheimer’s the hippocampus nerve cells die first. The loss of judgement and linguistic skills occur once the cerebral cortex is dead (Science Direct). The diagnosis for Alzheimer’s relies on the documentation of mental decline but not limited to lab tests, neuroimaging and other neuropsychological tests.…

    Alzheimer’s disease (AD), was discovered as senile form of dementia in early 1907 by Alois Alzheimer in 1907. Since then the disease has been researched and studied to generate a knowledge base of symptoms, etiology, pathogenesis, treatment and management of the disease. AD is differentiated from senile dementia due to the neurodegenerative process which involves deposits of protein known as amyloid in neurons and neurofibrillary tangles which form plaques. This formation of plaques leads to neuron death and the hardening of tissue leads to progressive and terminal neurological disease state. There has been no cure to Alzheimer’s disease to the complexity of disease and the lack of understanding of amyloid protein and its process.…

    Even though the brain may reject when you get older, it does not lack neurons in Alzheimer’s disease, but the damage is larger and many neurons stop being active and become sterile with other neurons, and eventually die. Alzheimer’s blocks vital communications to neurons and their networks, including relations, metabolism, and restore. At first stage of the disease, it breaks neurons and their communications in parts of the brain that are joined with memory, it later breaks part of cerebral cortex managing your speech, awareness, and behavior. Ultimately, there are many other areas of the brain that are broken, and a person with Alzheimer 's becomes disabled for everyone. When neurons lose their links, they cannot work right and finally die.…

    When examining patients with Alzheimer's, it was noted that the cells of the hippocampus and layers of the entorhinal cortex are affected. The affected cells that interconnect the hippocampus, associated cortices, thalamus and hypothalamus are essential for memories. Often patients with AD also have Vascular Cognitive Impairment and Dementia. More progressed cases will present with deficits in language, reasoning, and social behavior. When the disease progresses past this point, a person with Alzheimer's will lose their ability to function and carry out their day-to- day activities by themselves.…

    Health Issue Alzheimer’s disease is an irreversible and progressive brain cell degenerative disease that causes a steady decline in memory and mental functioning (“Overview,” 2015). As the most common form of dementia, the causes of Alzheimer’s disease may vary and result from a combination of multiple disorders that alter brain changes such as, clumping of amyloid plaques, tangled neurofibrillary or loss of connections between nerve cells in the brain (“Alzheimer's Disease,” n.d.). Currently, Alzheimer’s disease is the 6th leading cause of death in the United States. The Alzheimer’s Association states that there are more than 5 million people diagnosed with Alzheimer’s disease in the United States and 35 million people worldwide.…

    Following her death, Dr. Alzheimer performed an autopsy, during which he found dramatic shrinkage of the cerebral cortex, fatty deposits in blood vessels, and atrophied brain cells. He discovered neurofibrillary tangles and senile plaques, which are indicative of AD. The condition was first discussed in the medical literature in 1907 and named after Alzheimer in 1910 (Graeber et al., 1997; Graeber et al., 1998; Graeber and Mehraein, 1999; Maurer et al.,…
