Causes and Risk Factors of Alzheimer disease

Question

Description

My english teacher is extremely harsh on her grading. Says that the thesis should focus on symptoms, diagnosis, treatments, causes etc. For the four needed sources, two need to be periodical sources, one of which should be a scholarly journal, and one current event article written in the last two years. Also has to be written in first person. Sorry my english teacher is such a hassle... It's only english 101 but she treats it like i am in grad school getting an english degree.
