Round 1 of 5
A 24-year-old man has had unwanted, intrusive thoughts for 8 months that door handles carry germs that will make his parents seriously ill, and he tries to push these thoughts away. He washes his hands in a fixed sequence for about 2 hours a day to ease the anxiety, often arrives late to work because of it, and states he has no concerns about how he looks.
