With my personal hopes of becoming a doctor someday, the title of this article immediately peaked my interest. A study by The Archives of Neurology promoted Professor Denise Head to begin an experiment at Washington University in St. Louis. The experiment gathered 201 patients who had not shown any clinical symptoms of Alzheimer's with some who did have a family history. In the experiment, the scientists scanned their brains for amyloid plaques (flashing red lights for Alzheimer's), a variant of the APOE gene, which is involved in cholesterol metabolism, called e4 (multiples the risk for Alzheimer's by 15%), and asked for a history of exercise habits. The reports came in that people who exercised at least 30 minutes for five times a week had less amyloid plaques than those who didn't exercise. Another result was that those he did have the APOE-e4 variant gene had a lot of amyloid plaques, unless they had a history of exercise. The exercise by those who had the variant gene had equal levels of amyloid plaque to those negative e4 variants. This is good news for those patients who know they have a family history of Alzheimer's.
The author of "How Exercise Might Be Able to Help Fight Alzheimer's", Gretchen Reynolds, uses a lot of logos appeals. One of her logos appeals was how well she reported on the experiment performed, its process, its location (Washington University in St. Louis), and its results. Reynolds explained the difficult scientific jargon so that anyone who was not from the science field or didn't know anyone with Alzheimer's could understand difficult things like the amyloid plaques and the APOE-e4 variant. Another logos appeal that Reynolds uses is her quotes from the most relevant person in the experiment, Dr. Denise Head, who conducted the study. The audience can definitely rely on her words and Reynolds for knowing who to talk to. The diction of this article is mainly that of medicine and genetics, such as "amyloid plaques," "APOE," "e4," and "positron emission tomography". However, unlike previous articles that I have read, Reynolds made her article "How Exercise May Keep Alzheimer's at Bay" understandable for most audiences about another positive step in the fight against Alzheimer's.
