It’s sad that someone who cannot feed themselves and others who can’t even get out of bed without the assistance of another person have to live their lives everyday the same way because of Alzheimer’s. One of the biggest mysteries to me is Alzheimer’s and dementia. Everything about it baffles me, from the different ways it progresses to the impact it has on the person’s ability to function as a normal human being. It is estimated that up to 4.5 million Americans suffer from Alzheimer’s disease. Many tend to forget

that it is a disease and not a normal part of aging. Alzheimer’s is a disorder in the brain that was named after a German physician drew attention to it in 1906. He discovered this after noticing unusual formations in the brain of a deceased woman. In this woman’s brain he found formations called plaques, which is a build up between the nerve cells, which contain deposit of protein fragments called beta-amyloid. He also found formations called tangles, which are twisted fibers of protein called tau, tangles however form inside of dying cells. Although they are not sure scientists believe these formations block communication among nerve cells and disturb activities the cells need to survive. This might also have to do with the fact that they have found victims of this disease have lover levels of some of the chemicals in the brain that carry messages back and forth between nerve cells. It might be as simple as the brain just cannot connect and receive the information it needs to survive. Let’s get a little detailed on how this disease affects the brain. Alzheimer’s leads to nerve cell death and tissue loss throughout the brain. After a period of time it shrinks dramatically. The cortex shrives up, damaging areas involved in thinking, planning and remembering. Shrinking is very severe in the hippocampus, which has a key role in forming new memories. The ventricles or fluid filled spaces in the brain grow larger as

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
