Round 1 of 5
An 8-year-old boy has had explosive tantrums since age 6, with screaming, kicking doors, and throwing objects over minor frustrations, averaging four to five episodes per week at both home and school and lasting far longer than the trigger warrants. Parents and teachers describe him as grumpy and angry most of the day nearly every day between episodes, with no break of even a month in the past 18 months and no history of distinct periods of elevated mood, decreased need for sleep, or grandiosity.
