2 Decision Tree for Neurological and Musculoskeletal Disorders Alzheimer's Disease (AD) is a devastating, progressive disease in which patients' cognitive function and memory decline over time (Rosenthal & Burchum, 2017). Alzheimer's Disease has become one of the most challenging diagnoses of the century (Kuo et al., 2020). The underlying cause for Alzheimer's is unclear; however, some risk factors have been determined. Possible risk factors include over 65 years of age, head injuries, low educational level, low levels of folic acid, high levels of homocysteine, estrogen/progastrin therapy, and smoking (Rosenthal & Burchum, 2017). The purpose of this paper is to summarize the case study of an Alzheimer's patient, discuss appropriate pharmacology and diagnostic treatment. Case Study on 76-year-old Iranian Male with Alzheimer's Disease Mr. Akkad, a seventy-six-years old male from Iran, presents to the office with his son due to continued strange behavior. Son reports that his father has been demonstrating strange thoughts and behaviors over the last two years. According to his son, Mr. Akkad is forgetful and has significant personality changes. Mr. Akkad has been seen by his physician, who ruled out any organic basis for behavior (Laureate Education, 2019). During the mental health exam, the patient had poor eye contact, speech is clear and coherent, but lacks insight of his present health condition and doesn't appear to have good judgment.There are no unusual motor movements or tics noted. The effect is restricted, he does seem to enjoy the conversation. No delusional or paranoid thought processes were documented.
