A 7-year-old boy is brought to the psychiatric clinic by his mother, who reports that his second-grade teacher has expressed concerns about his inability to stay seated, frequent interruptions during class, and difficulty completing assignments. His mother notes that he has always been an active child but that his behavior has worsened since starting second grade. She reports that he loses his homework frequently, cannot follow multi-step instructions, and becomes frustrated easily when tasks require sustained mental effort. His developmental history is unremarkable, and he met all milestones on time. He has no significant medical history, and a recent physical examination by his pediatrician was normal. His mother also mentions that his biological father was diagnosed with ADHD as a child. The PMHNP is planning the initial assessment.
