  • The Byproduct Of Alzheimer's Disease

    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.…

  • Amyloid Beta Protein Analysis

    INTRODUCTION Alzheimer’s disease is a progressive neurodegenerative disorder characterized by memory loss and dementia. The neurodegeneration is due to a formation of amyloid platelets in the brain that interrupt the normal function of it. It worsen with the pass of years and is mostly suffered by older people (Reece et al. 2014). The platelets composed by Amyloid; a harmful insoluble protein fibril which is produced by Amyloid precursor protein (APP). APP is processed in the membrane of neurons…

  • The Effects Of Alzheimer's Disease

    Alzheimer’s disease (AD) was first discovered in 1907 by Alois Alzheimer, a German psychiatrist and neuropathologist. He noticed that the brain tissue of a recently deceased woman was exhibiting strange abnormalities. Upon further examination he discovered abnormal clumps and tangled fibers; which are now known as amyloid plaques and tau tangles. Alzheimer’s disease is an irreversible and progressive brain disorder characterized by memory loss and loss of cognitive abilities. While Alzheimer’s…

  • Amyloid Cascade Hypothesis By Karl Herrup: Article Analysis

    Herrup attempts to disprove the hypothesis and looks forward to other possible hypothesis. After looking pointed towards animal studies, it was seen that animals can have large amyloidal burdens in their brains but still do not have any signs of dementia (Herrup, 2015). This shows that although the hypothesis could show that there are cases where people have the large burden and have Alzheimer’s disease, it is also possible that a person with the disease does not need to have the amyloid…

    and sulfur. There are many different kinds of proteins, each with a different function. Collectively, they are essential for the proper functioning of an organism” (Comer, 2014). Comer also explains that, “The plaques and tangles that are so plentiful in the brains of Alzheimer’s patients seem to occur when two important proteins start acting in a frenzied manner. Abnormal activity by the beta-amyloid protein is key to the repeated formation of plaques” (2014). Researchers have found that…

  • Alzheimer's Disease Case Study

    Five million Americans have Alzheimer’s Disease and it causes up to 500,000 deaths each year (Marsa, 2015, p. 6). Alzheimer 's is a brain disorder, which currently has no cure, it not only affects the patient but the loved ones surrounding them.This disease causes problems with judgement, memory and overall thinking. In the human brain, plaques are clusters of protein fragments called beta-amyloid peptides (Marsa, 2015, p. 7). They collect outside the nerve cells and disrupt the signaling…

  • Essay On Heart Failure

    They block the effect of adrenaline that is a vasoconstrictor. Adrenaline constricts the blood vessels causing increased blood pressure. High blood levels overwork the heart leading to an increased size of heart muscles in turn failing the heart. Beta-blockers lower the heart rate which decreases heart 's oxygen demand. Beta blockers also decrease rennin production reducing oxygen demand of the heart. They are used in the long-term management of chronic failure of the heart. Examples of this…
