Effects Of The Brain On Alzheimer 's Disease

With Alzheimer’s disease the brain becomes smaller and has narrower gyri and wider sulci, mainly in the frontal and temporal lobes (Gould, 2011, p. 522). Alzheimer’s disease affects three processes that keep neurons healthy: communication, metabolism, and repair. There are specific nerve cells in the brain which stop working and drop their connections with other nerve cells, and then they completely die (Anderson). The death or deterioration of the nerve cells is what impairs the memory in those who suffer with Alzheimer’s disease. The plaques, which disrupt the neural conduction, contain fragments from beta-amyloid precursor protein; the role of

The loss of cognitive function is associated with fewer nerve cells and synapses than the normal brain. The neurons demise is thought to be from the formation of plaques and tangles. The formation of these plaques and tangles can begin many years before the person becomes symptomatic of AD. The formation of plagues comes from the breaking down of a protein in the cell membrane into protein fragments called beta-amyloid. The YouTube video, NIH: Unraveling the Mystery of Alzheimer's Disease, provides a clear animation how the beta-amyloid plaques are formed as these sticky fragments begin to clump together. (National Institutes of Health, 2011) The video shows another protein called tau, involved with formation of tangles. The tau protein is instrumental in the transport of food molecules, parts of cells, and key building materials and is compared to a railroad track system. The tracks become unraveled and form tangles. In the earliest stages of the disease, the plaques, and tangles form deep inside the brain in the medial areas where learning and memory are formed, then progresses toward areas where thinking and planning occur as the neurons begin to die. Because of the billions and billions of cells in the neuron forest, the damages caused by the plaques and tangles may go undetected and be asymptomatic for

Alzheimer 's disease (AD) is a progressive degenerative disease of the brain from which there is no recovery. There are three brain abnormalities that are the hallmarks of the Alzheimer’s disease is initially caused by plaques buildup in the brain’s neurons as illustrated in figure 1. The support structure that allows the flow of the nutrients through the neurons gets damaged and ultimately there is loss of connection among the neurons and they die off (National Institute of Health, 2015). This causes the brain tissue to shrinks, which is called atrophies. All this ultimately lead the victim of this disease to face difficulties in governing emotions, recognize errors and patterns, coordinate movement, and remember. Ultimately, a person with AD loses all memory and mental functioning.

Alzheimer’s is a disease in the brain that affects a person’s memory, thinking, and behavior. It is the most common form of dementia and is common in adults older than 65. More than five million Americans are being affected by Alzheimer’s at this moment. Alzheimer’s comes in three stages; early, middle, and advanced. The disease is caused by the shrinking of the brain due to many risk factors and genetics.

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 8 (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).

According to data available from the Alzheimer’s foundation every 67 seconds someone develops Alzheimer’s disease and currently at least 5.3 million people are affected by the disease. The numbers are expected to grow as 75 million baby boomers transition into retirement by 2030. Alzheimer disease is a brain disorder that causes decay and dis- function of neurons resulting in memory loss, speech and language impairment. This can also extend to challenges in physical and social behavioural. The brain, consisting of the cerebrum, cerebellum and brain stem is the primary target of Alzheimer’s disease. At three pounds the brain has a network of arteries and a folded cortex that is responsible for memory and movement. These functions are facilitated by a network of neurons. Alzheimer’s disease interferes with these neurons by disrupting electrical transfer; Death of brain cells is inevitable as the cortex shrinks becoming incapable of developing thoughts and memory. The Alzheimer’s patient experiences an altered personality with family members becoming strangers.

Alzheimer’s disease is a progressive brain disease which slowly destroys thinking and memory skills. These changes are severe enough to interfere with day to day life. This irreversible disease is the most common cause of dementia amongst the elderly, with an appearance of first symptoms after age 60.

As per Lakhan (2017), Alzheimer's disease (AD) is a disorder dealing with neurodegeneration manifesting the cognitive and behavioral impairment that extensively affects the lives of the people who have the disease. It doesn't have a cure and deals with a long pre-clinical period as well as a progressive course. In hippocampus and some areas of

Alzheimer’s disease (AD) is a form of dementia that causes problems with memory, thinking, and behavior. AD typically involves the development of a progressive neuropsychiatric disorder that is characterized by gradual memory impairment, loss of acquired skills and emotional disturbances (Lee, Y. J., Han, S. B., Nam, S. Y., Oh, K. W., & Hong, J. T.). Every 67 seconds an individual in the United States develops AD. AD is the sixth leading cause of death in the United States. There are 5.3 million Americans diagnosed with AD (Latest Alzheimer's Facts and Figures). AD is one of the few degenerative diseases that cannot be prevented, stopped, or cured (Latest Alzheimer's Facts and Figures). Post-mortem examination of the brain of AD patients usually

In the mild stage of Alzheimer’s the symptoms could include: difficulty coming up with the right name, problems remembering names when meeting new people, difficulty performing tasks, forgetting material you’ve just read, losing and misplacing objects, and trouble planning and organizing things. The second stage is moderate Alzheimer’s disease which is the middle stage. It is known to be the longest stage and can carry over for many years. As the disease continues, the person affected with the Alzheimer 's disease will require more care. Symptoms include: forgetting about their own history, feeling moody, not being able to remember phone numbers or their name, confusion on what day it is, problems controlling their bladder, changes in their sleep patterns, and becoming lost. The last stage is severe Alzheimer’s. People lose the ability to respond to their environment, to hold a conversation and, to control movement. Symptoms include: require assistance full time daily, having difficulty communicating, become vulnerable to infections like pneumonia, and changes in physical abilities like walking, talking, and swallowing. There is no cure for Alzheimer 's but drug and non-drug medicines may help with all the symptoms.

Alzheimer’s disease is a neurodegenerative disorder, meaning it attacks the neurons within the brain. Neurons are the areas of the brain that allow for chemical messages, or neurotransmitters, to be transmitted. These neurons are necessary for connections with other nerve cells, and without them, the neuronS ultimately die. Alzheimer’s is a form of, and the most common cause of, dementia, or loss of intellectual capacity and personality. ("Dementia.") Alzheimer’s disease, or AD, is not a normal part of aging, although risk of developing the illness increases with age. The onset behavior of the disease normally doesn’t appear until age sixty and older. Though symptoms that appear before age sixty have occurred, it is less common and tends

“Alzheimer’s disease is a progressive condition that destroys the connections between cells in the brain.” (WebMD, 2014). As the cells die the cortex shrinks. The part of the brain that is impacted the most in dementia is the cortex. The cortex includes the hippocampus. This helps new memories form. If there is damage to this part of the brain, there will be problems with the person memory.

Alzheimer’s disease is a form of dementia, a disease that according to the Alzheimer's disease Education & Referral Center is defined as: “…a group of symptoms that are caused by changes in brain function”. According to the National Institute on Aging in a book entitled “Alzheimer’s Disease, Unraveling the mystery” the authors chronicled that Alzheimer’s disease affect people in different ways. The most common and noticeable symptoms are: 1). Memory loss that disrupts daily life 2). Challenges in planning or solving problems

Alzheimer’s disease is a very slowly progressive disease that occurs inside the brain in which is characterized by damage of memory. Also this type of disease can lead into interruption in language, problem solving, planning and perception. The chance of a person developing Alzheimer’s disease increases enormously after the age of 70 (Crystal, 2009). Also people who are over the age of 85 have over a 50 percent chance of developing Alzheimer’s disease. This type of disease is not at all normal in the aging process and is also not something that happens out of no where in a person’s life.

However, some scientific studies show that Alzheimer disease occurs when nerve cells in numerous key areas of the brain are destroyed or damaged. The damaged or destruction of these nerve cells in the brain disrupts the information flow between the body and the brain. This disruption leads to a stable decline of both mental and physical functions. Scientists say that the destruction of the brain is most likely to be caused by the development of senile plaques (clumps) and neurofibrillary tangles (knots). These plaques and knots are usually found on the brain of a diseased person during after death biopsy. They are mostly found on the part of the brain that is associated with the memory and retention of information (National Institute Of health 10).
