Essay / Research Paper Abstract
This 9 page paper discusses how the brain changes as it ages and the effects those changes have on people. The writer identifies the primary processes relative to changes in the brain. The writer discusses memory, perception, senses, reaction time and other functions. The paper includes results of a research study comparing older and younger people in terms of which part of the brain they each used. Bibliography lists 10 sources.

Unformatted sample text from the term paper:
specifically in the aging brain over the last two decades and scientists have learned a lot. Even with all this study, we still do not know that much about what
happens and how some people get diseases like Alzheimers and other people do not. In fact, scientists do not agree on whether Alzheimers is a disease or a severe case
of aging. And, if it is a disease, what types are there, what causes it and how should it be best treated (LifeTwo LLC., 2009). And, we do not know
exactly what happens in a normal aging brain. There are two primary processes for the aging brain. There is the accumulated wear-and-tear damage that comes from things like stress, injury,
oxidation and even errors found in the DNA of the brain (LifeTwo LLC., 2009). The second is referred to as pruning of synapses, which is believed to be a normal
process. Basically, the brains neurons just do not make as many synapses as it once did and that interferes with things like problem solving. Scientists have found that beginning at
about age 25, senile plaques begin to develop and by age 40, a person will have neurofibrillary tangles (NFTs) (LifeTwo LLC., 2009). Both of these can lead to decreases in
certain functions. What is different between todays research and that of decades ago is that scientists now believe that a person does not lose brain cells unless they have a
disease that affects the cells (LifeTwo LLC., 2009). We know water in the cells decreases. Like everything else, the brain changes as it ages but it does not change
in the same way at the same speed for everyone. The changes may begin as early as age 30 (LifeTwo LLC., 2009). Our minds become a little slower as we
