Kathryn Moffett, MD

The patient is a healthy 5-year-old boy who typically awakens 90 minutes after falling asleep. His parents find him screaming, sweaty, and standing up wide-eyed in bed (Figure A). These episodes occur 3 or 4 times a week. He is otherwise a happy, well-adjusted child who attends kindergarten. He has an older sibling with whom he gets along well. There have been no changes in the family.
