A 23-year-old man is brought into the emergency department after he was found wandering around a train station. He is alert and oriented to the emergency room, but cannot give his name. His wallet contains a driver’s license with his photo, but he denies recognition of the name on the license. He cannot explain why he was at the train station and cannot provide any details on his living situation, job, or family. The emergency contact in his phone leads to his mother, who states that her son “disappeared” after finding out his ex-girlfriend, whom he broke up with last week, is pregnant. Physical examination and urinalysis are both normal.
Which of the following is the most likely diagnosis?
- A) Depersonalization/derealization disorder
- B) Dissociative amnesia
- C) Dissociative identity disorder
- D) Malingering
- E) Transient global amnesia
