1. A 27-year-old black male was brought to the hospital for evaluation after a “crazy”
episode
while taking a walk with his girlfriend in a park. He was witnessed to be suddenly
very horrified, threw himself to the ground seeking for cover. During the interview he
appeared quite coherent. He said he saw an attacking helicopter in the air and he was
trying to rescue himself. He is an Iraq veteran who was honorably discharged 14 months
ago after his 1-year service in Iraq. His live-in girlfriend reported that he had no known
psychiatric history before his service in Iraq, and no apparent difficulties in returning to
civilian life after the discharge. However, she had noticed that he was reluctant to talk
about his military experience. In the past 4 months, he experienced depression, insomnia,
and flashbacks of his wartime experience. He also became preoccupied with news
stories about Iraq. He began to have difficulty sleeping, and often woke up in the midst of
nightmare. The “visual hallucinations” of his wartime experience had appeared several
times but usually were very brief. He said this was the first time that he became “crazy.”
