Alzheimer, a type of dementia, is a progressive brain disease. It affects the brain in many parts for memory, thinking, behavior, comprehension, and speech deteriorate. There can also be some physical problems as loss of coordination, incontinent and unable to do for themselves. “As many as five million American are living with Alzheimer’s disease. Today it is the sixth-leading cause of death in the United States” (Alzheimer’s Association). People can suffer with the disease for up to twenty years, but the average length is nine years. “About ten percent of all people over seventy have significant memory problems and about half of those are due to Alzheimer’s” (Health Guide). The rate of the progression of the brain is determined on how fast cells are being killed. “The brain has 100 billion nerve cells (neurons). Each nerve cell communicates with many others to form networks” (Alzheimer’s association). The cells start to stop and become damaged. They shut things down that helps us work. The cell becomes damaged by two forms of nerves, neurofibrillary tangles and plagues. Neurofibrillary tangles form from inside dying cells. Plaques build up between nerve cells, which has deposits of protein parts called beta-amyloid. Majority of people can have both, tangles and plaques, although people with Alzheimer’s tend to develop far more. “Researchers are not yet sure why or how these processes occur, but some of the most recent research points to a normally occurring blood protein called ApoE (for apolipoprotein E), which is required for the transport of fatty substances in the body” (Basics of Alzheimer’s disease). The form of ApoE that each person has is genetically determined. All other proteins are genetically determined also. If one of your parents had Alzheimer’s, you will be at a higher risk to develop the disease. Researchers think that in some way they seem to...
