For this assignment, imagine you are an interning psychiatrist assigned to the state mental hospital. One of your duties as an intern is to make an initial diagnosis based on a history you take upon a patient's arrival. Later, a team of doctors will evaluate your initial assessments to determine your professional competence. For each of the five case studies given below, list the symptoms and then state your diagnosis and the rationale behind it. Consult the DSM website for help. Case 1: Kristin, age 20, is a first-year college student. This is her first time away from home, and she worries about her family a lot, as her parents are going through a bitter divorce and she has a little brother at home. Kristin is having trouble concentrating on her studies and has been complaining about various physical problems. Sometimes she has sudden, unexplained attacks of fear, and sometimes, for no apparent reason, her heart races, she has chest pains, and she gets sweaty all over. She sometimes also feels nauseated and dizzy. At first she thought she might be having a heart attack, but a medical exam found that her heart was fine. Case 2: Shelby, a 13-year-old girl, is brought in by her mother. The mother is concerned about Shelby's "unusual" bedtime routine. Before going to bed each night, Shelby spends exactly one hour writing all the events of her day in minute detail in a special journal. She then picks all of the hair and lint off her bed and folds her sheets back until they are "just right." She then spends anywhere from 10 to 30 minutes brushing and flossing her teeth. Finally, after lying down in bed, she calls out good night to each person in the family. If everyone answers, she can sleep; otherwise, she gets up and checks on those who didn't respond. She then goes back to bed and starts the "call out" ritual again. If she wakes up during the night, she has to "call out" again before falling back to sleep, which is disruptive to everyone's rest. Case 3: Carl, age 32, is an assistant principal at a local high school. He came to the hospital today because of some "blackouts" he's been experiencing over the past six months. The first one occurred after the worst day in his personal life and professional career. That day, his wife revealed that she'd been having an affair with one of his coworkers and wanted a divorce. He then left the house to get some space and think, but couldn't remember what happened afterward. He "came to" in the parking lot of a movie theater about 100 miles from his home. He has had four more blackouts since that time, though he's never "come to" as far away from home as the first time. Case 4: Lyndsi is a 22-year-old woman who was just brought in from the emergency room of the adjacent hospital. She was reportedly found at a McDonald's trying to cut her wrists with a plastic knife while rocking back and forth. When the manager approached her and tried to talk to her, she was unresponsive. A moment later, she screamed that the people in the hamburgers were making her cut. She remained agitated until the police came, and she kept talking about "them." Case 5: Becky, age 42, was brought in by local law enforcement after she was found running naked through the town park. When asked what she was doing, she said that it "felt good to be free." When the police asked her to come with them, she became combative and had to be handcuffed. She continued to hiss and spit at the officers until arriving at the hospital, where she smiled broadly and yelled, "Home sweet home!" During your interview with her, she seems very excitable but pleasant. She mentions that her run through the park was a celebration. When you ask what she is celebrating, she says that she has been feeling rather down for the past two weeks, but that today she felt great and decided to celebrate with a run.
