While we have not discussed Alzheimer's specifically in Diagnostics & Therapeutics classes, there will be questions on your certification exams regarding Alzheimer's and Dementia. Your textbooks also have excellent information on these disease processes, so pay special attention to Risk Factors, History, Physical Exam and the Plan of Care/Education for each. You will only be asked about the basic drugs for Alzheimers such as Exelon, Aricept etc., of course by generic names. You must know the MMSE by heart.
