She has not seemed confused after waking up, and she is consolable and able to fall back asleep in her parents bed. The following day, she seems more tired than usual at school. She recalls that she had a bad dream and looks for ways to delay bedtime in the evenings. She has met all her developmental milestones to date. Physical examination shows no abnormalities. Which of the following is the most likely diagnosis?? A: Sleep terror disorder, B: Post-traumatic stress disorder, C: Normal development, D: Nightmare disorder, E: Separation anxiety disordern,  <response>: This seems to be a question asking about a diagnosis for a child with nighttime waking and bad dreams. Based on the information provided, the key factors are:- 8 year old girl- Waking up frightened 1-2 times per week for 2 months- Yelling and crying when waking up- Not confused after waking, consolable- More tired than usual the next day- Recalls having a bad dream- Avoids bedtime- No developmental delays- Normal physical examThe description of waking from sleep frightened and crying after a bad dream, with no other symptoms, matches most closely with nightmare disorder. The other options can be ruled out: sleep terrors do not involve recalling a dream, PTSD requires a traumatic event trigger, normal development would not lead to distressed awakenings and bedtime avoidance, and separation anxiety seems unrelated.D: Nightmare disorder
