The Byproduct Of Alzheimer's Disease

Improved Essays
According to the National Institute of Aging, “Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks,” (Fact). Alzheimer’s disease is the most common form of dementia (Association). It causes disturbances in metabolic processes that are vital to keeping neurons healthy. These disturbances cause nerve cells to stop working, lose connection with other nerve cells, and eventually die. This causes memory loss, behavioral issues and problems with critical thinking (Fact).
Causes
Amyloid plaques are essential when it comes to Alzheimer 's disease. Plaques are abnormal clusters of protein fibers between the nerve cells, as seen in Figure 1. They can be formed when pieces of a protein, also known as, beta-amyloid, begin to bundle together. The beta-amyloid are smaller pieces to a large protein that is found in the fatty membrane surrounding the nerve cells. Beta-amyloid stick together and eventually form plaques. Small clumps of beta-amyloid are more damaging than the larger ones. This is because the small clumps can possibly block the cell-to-cell synapses. Although, scientists have not been able to link plaques to the cause of the disease. Some believe that it is a byproduct of Alzheimer’s disease.

This disease disrupts very important processes that the nerve cells must carry out in order to survive, including communication, metabolism, and repair. At first, the disease impair nerve cells and their communication in the parts of the brain that are involved in memory. Eventually, the disease destroys the parts of the brain that deal with language, social behavior and reasoning. Afterwards, more and more parts of the brain become damaged and the person becomes unresponsive to the outside

    Alzheimer’s Disease Alzheimer’s, which at its worst case is referred to as dementia, is a progressive disease that eats away at the brain and controls the ability to function (Horr 2015) According to Mitchell Clionsky, this disease is common among people of older age causing a mental dysfunction triggering the ability to think, remember and reason as well as behavioral abilities. (Clionsky 2015) These factors can drastically affect the body emotionally. Some patients get frustrated and mad due to not remembering certain tasks that needed to be completed. It’s definitely not easy to have a disease like this, to forget the memories, the last phone call conversation or to even forget what was consumed for breakfast. People diagnosed will eventually…

    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.…

    Parkinson’s disease- a decrease in the substance dopamine that the body makes naturally causes problems with the physical body. There is forgetfulness also but the most common visible teller of Parkinson’s is the shaking. The memory side of Parkinson’s is like the above diseases. Many of the diseases are thought to begin by the enzymes in the brain, if there is an abnormality, or if there is an excess or too much. As the medical science world develops so will the understanding of the diseases that do contribute to…

    What is Alzheimer’s disease? How is Alzheimer’s disease formed? Alzheimer’s disease is a type of dementia that destroys memories, thinking skills, and causes drastic changes in behavior. In which the brain is losing nerve cells also called neurons caused by “Tangles” and “Plaques.” They are both formed up out of two different types of proteins which are called Beta-Amyloid protein and Tau Protein. These proteins are usually formed to help our brain cells’ communication.…

    There are two types of irregularities that are the trademark for the infamous disease: Plaques and Tangles. Plagues are clumps of protein called beta-amyloid. These obstruct cell-to-cell communication with your neurons. Tangles occur when two threads of Tua protein twist together. This inhibits the Tua which in normal healthy circumstances provides the neuron with essential…

    Plaques, abnormal clusters of protein fragments, build up between nerve cells. Dead and dying nerve cells contain tangles, which are made up of twisted strands of another protein. Scientists are not positive of what causes cell death and tissue loss in the Alzheimer 's brain, but plaques and tangles seem to be the cause. Plaques are formed by protein pieces called beta-amyloid. Beta-amyloid comes from a larger protein found in the fatty membrane surrounding nerve cells.…

    Also, new proteins have a tendency to fold incorrectly and due to the above reasons, proteins will most likely aggregate (Tutar et al., 2013). With that, I conclude that proteins are essential in carrying out almost all of the functions in our body and the aggregation or misfolding of these proteins may cause neurodegenerative diseases. These diseases will lead to the death of our cells and have negative consequences on our motor skills as our muscles will be…

    The three main symptoms for each stage of Alzheimer’s are stage 1: Memory impairment – memory is affected, not being able to remember people’s names or misplacing object’s. Stage 2: Behavioral changes- because of memory loss this causes the disease to continue to take over the brain which will cause frustration or anger. Stage 3: Independence- Alzheimer’s takes over the brain to a point…

    Individuals who have AD have mental or cognitive impaired. They are mentally impaired due the spreading tangle and plaque in the brains. They will not be able to remember a lot of things, even family members. The brain and body become dysfunctional because of the numerous dead brain cells. The individuals with AD become dependent on family and people around them who are still physically and cognitively functioning.…

    . (Alzheimer’s Disease Genetics) These clumps of beta-amyloid block communication amongst other cells sometimes leading to inflammation of the brain. The tangles consist of a protein called tau. Tau allows food molecules to travel along “tracks”. When tangles are formed the “tracks” no longer remain straight and fall apart and disintegrate.…
