A Disease That Is Common On Age 60 Or Older - 1388 Words

Abst [Alzimer it s a disease that is common on age 60 or older. This disease is named after Dr.Akois Alzheimer, in 1906. He notist some changes in the brain tissue of a woman who have died and had a mental problem. her mental symptoms was loss the memory, language problem, sand some communication behavior. When he was examined her brain he found some abnormal clumps, and tangled bundles of fibers. === Alzheimer is a disease memory and thinking skills. At first, people have hard time remembering recent event, but as time go they lose the ability to carry out the simplest task, such as, focusing, felling confused or frustrated especially at night. Dramatic mood swing has a treble to communicate with others and some†¦show more content†¦Functioning, that means they lose connection with other neurons and they almost die. They start damage the any place in brain they damage the hippocampus the main part of the brain that its in charge to forming memoirs as more neurons die, more part of the brain are affected and by the final stage brain tissues has shrunk significantly. The brains of the people with the Alzheimer disease are under fluent of two structures- amyloid plaques and neurofibrillary tangles are made of misfiled proteins and the this main is the loss of connection between cells. This ends by cell death. Amyloid Plaques An amyloid plaque is finding between the brain cells. It forms when protein pieces called Bata-amyloid- clump together. They come from large protein from fatty membrane around nerve cell. Beta-amyloid is chemically â€Å"stinky† and builds up into plaques. For a long time scientist thought that plaques might cause all of the damage to neurons that is seen in the Alzheimer disease. But now many scientists think that oligomers may be a major culprit. The other group also thinks that plaques might be a late stage of attempt by brain to get this harmful beta-amyloid away from neurons. Neurofibrillary Tangles The second imported, tangles are abnormal collections of twisted protein that found inside nerve cell. The chief of tangles is tau it’s a protein cell. The neurons that are healths are internally supported is some part by
