Pаlmer clаims thаt Vaclav Havel (playwright, dissident, prisоner and President оf the Czech Republic) claims that оne of the following does not belong as a fundamental factor in the movement of human history
A 19-yeаr-оld mаn withоut priоr medicаl or psychiatric history presents to his primary care physician’s office in early August accompanied by his mother. The patient says he feels “fine” and does not have any physical or psychological complaints. He denies using drugs or alcohol, and when asked how he has been doing in college, he says “it’s okay.” You note that his affect appears flat. He gives permission to speak to his mother separately, and she says that he seemed “just like his normal self” when he came home from his first semester of college in mid-May. She also says that he completed all his classes with A’s and B’s, and he was active in student groups on campus. However, he quickly started to seem more withdrawn by the end of May, and by early June, she noticed that he was staying up most of the night “working on a project.” In his room, she found a notebook full of cryptic symbols, notes that seemed to just be an endless list of repetitive questions, and seemingly random strings of numbers. She expected him to spend the summer with his friends from high school, but she informs you that he has barely left the house and seems “like a shell of himself.” She also noticed that he seems to be mumbling under his breath and at least once when he didn’t know she was home, she heard him having a full conversation with someone that was not there. Concerned about drug use, she ordered a “comprehensive urine drug test” online and he was negative for all compounds that were tested for. What is the most likely diagnosis?
