Cece is a 73 year old woman who retired from her job as a department store cashier 2 years ago, after 40 years of employment. She has been married for over 30 years and lives with her husband. She also has 2 adult children, who are in good health. Her son is a high school teacher, and her daughter is nurse at a large metropolitan hospital. Cece has a grandchild whom she sees once or twice a year when they visit from out of state. Recently, Cece has been experiencing memory loss and fatigue. It takes her longer to complete normal daily tasks that she used to perform with much more efficiency in the past. She is more irritable than before, and she even lost her way home from the local store once. After consulting with a neurologist, she was told that her symptoms are early signs of a neurological disease.
Linda is Cece’s twin (identical) sister. Linda works as a Laboratory Technician at a large hospital in the city. Linda has been divorced for nearly 10 years. She has 1 adult daughter, and 2 grandchildren who visit Linda nearly every weekend. Linda lives alone, but at least twice a week she has dinner a group of her friends, whom she has known for almost 20 years. After finding out about Cece’s condition and diagnosis, one of her friends told Linda that she should also expect to have the same symptoms soon, since she shares 100% of her genes with Cece.
What can you tell Linda about the the scientific evidence behind her friend’s claim?
I have attached the textbook chapters that should be used as well as the guidelines for answering this question.Response to the CT must be minimum 200 words. For all CT questions you must provide scientific evidence from the textbook for your response. Therefore, your response must include both your own ideas (critical thinking), as well as a minimum of one relevant quote from the related textbook chapter. You must clearly indicate why the quote you have selected is relevant to your answer. For example, if the topic is from Chapter 1, you must include a minimum of one quote from the textbook to support your own reflection (please underline the textbook quote and include the page number and the textbook module). You must also clearly explain how the quote you have selected relates (is relevant) to your answer. Even if you select to conduct outside research, minimum of one relevant quote from the textbook is required.
