The Nervous System Of Alzheimer s Disease - 2481 Words

A. Alzheimer’s disease The nervous system in general is quite a complex and sophisticated system which is responsible for regulating and coordinating the body’s activities. The central nervous system consists of the brain and spinal cord, mainly responsible for gathering information and responds to any changes within environment. Alzheimer’s disease known to be a neurological disorder of the central nervous system is an irreversible disorder in which brain cells deteriorate resulting to loss of our cognitive functions, primarily memory, movement coordination, reasoning and judgment, and pattern recognition. In its advanced stage, all memory and mental functioning could be lost (Healthcommunities.com, 2016). This disease is known to be caused by parts of the brain shrinking (atrophy), which destroys the structure and function of particular areas of the brain (Nhs.uk, 2016). Although the exact cause to this process is not known, research suggest that in the brains of patients with Alzheimer s disease, scientists have found amyloid plaques (abnormal deposits of protein), neurofibrillary tangles containing tau and acetylcholine a chemical imbalances (Nhs.uk, 2016). These Amyloid plaques are clumps of protein fragments accumulated between the nerve cells of the brain leading to its damage. In its normal state, these fragments are broken down and disposed but in the case of the Alzheimer’s disorder, these accumulated fragments form a rigid insoluble plaque on the neurons.Show MoreRelatedAlzheimer s Disease, Or Senile Dementia1715 Words   |  7 Pages Alzheimer s disease, or senile dementia, is a form of dementia that affects memory, thinking, and behavior. Brain cells and their connections are killed, and this is what causes people s brain functions to fail. Scientist have yet to know what causes Alzheimer s, but have discovered that age, family history, and genes contribute to developing the disease. Symptoms experienced by people with Alzheimer s are poor judgement, poor decision making, inability to manage a budget, losing track of theRead MoreAlzheimer s And Depression Effects Essay1720 Words   |  7 PagesIntroduction Alzheimer and depression effects an individuals’ occupations, independence and self worth, this will be the aim and focus of the following discussion. This discussion will explore the functions and disability of this scenario which includes, the primary body systems involved in Alzheimer s and depression including the structure’s and function’s. Then, how Lee’s (2003) occupations across the three areas of productivity, self care and leisure are affected. Furthermore, it will also exploreRead MoreAlzheimer s Disease : A Horrific Change1460 Words   |  6 Pages Alzheimer s disease which chronically leads to Senile Dementia, is a horrific change in homeostasis for human beings. The most obvious change in homeostasis from Alzheimer s is loss of memory. Memory loss can vary from short term to long term. Alzheimer s disease has been occurring in humans for a long time. This is a disease that affects different body systems, and interrupts homeostasis to a signi ficant point. As Alzheimer s disease is further investigated, there are more discoveries withRead MoreSymptoms And Treatment Of Alzheimer s Disease1063 Words   |  5 Pageshelp the effects of Alzheimer’s disease, many of these treat the symptoms but not the cause. One specific medication, cholinesterase inhibitors is not fully understood but it is believed to help decrease the breakdown of acetylcholine, a neurotransmitter (About Alzheimer s Disease: Treatment, n.d.). Cholinesterase is both beneficial in it’s aid in treatment and not— this medicine over time causes neurons not to produce as much acetylcholine (About Alzheimer s Disease: Treatment, n.d.). This drug worksRead MoreAlzheimer s Disease : The Most Common Form Of Dementia1427 Words   |  6 PagesDementia, known as one of the world s current pandemics, is estimated to be the fourth most common cause of death in the developed country, second only to cardiovascular, cerebrovascular diseases and cancer . With the aging population, dementia has gradually become a serious threat to the health of the elderly people in Australia. Alzheimer s disease is the most common form of dementia. Alzheimer s disease usually occurs in a primary degenerative encephalopathy in senile and pre senior periodRead MoreA Brief Note On The Alzheimer s Disease1709 Words   |  7 PagesCamryn Pillar Alzheimer s Disease Northview High School  There is a lot of sickness in the world today. The most significant and progressive illnesses are due to malfunction in the brain. One of the most common and deadly disease is Alzheimer s disease. It’s a progressive brain disorder that damages and destroys brain cells. This leads to many health problems that have very deadly impacts, and is irriversital. Sixty one percent of patients, at the age of seventy, are expected not to make itRead MoreMolecular And Cellular Mechanisms Of Toxicity And Cancer965 Words   |  4 Pageset al., 1997). A big number of epidemiologic studies relates the content of Aluminum in the drinking water with the increasing of the occurrences of neurological diseases. (Birchall et al., 1989) The Aluminum is accepted as a neurotoxic agent (Yokel, et al., 2000), and it has a relation with neurodegenerative diseases. Such as Alzheimer (Birchall et al., 1989). In animals used in researches, the first pathologic change is the accumulation of neurofibrillary tangles in large neurons, proximal axonsRead MoreAlzheimer s Disease : A Slow Progressing Neurodegenerative Disease Essay1694 Words   |  7 PagesAlzheimer’s disease (AD) is a slow-progressing neurodegenerative disease that has no cure and most often affects people over the age of sixty-five. Neurodegeneration is characterized by the loss of function in the central nervous system due to degeneration of neurons found mostly in the brain. The most recent data from the Center for Disease Control and Prevention shows that AD is the sixth-leading cause of death in the United States. The cause of Alzheimer’s is still not completely understood, butRead MoreEssential Nutrients For Creating Healthy Brains862 Words   |  4 Pagescorrespond with less cognitive decline as you get older and also delay the progression of Alzheimer. Vitamin K Vitamin K can help to prevent Alzheimer’s. One of the major functions of vitamin K is to regulate calcium in bones and in the brain age-related cognitive decline and neurodegenerative diseases such as Alzheimer s disease.
