In this installment of Tales From the Clinic: The Art of Psychiatry, we visit a bread-and-butter case of attention-deficit/hyperactivity disorder (ADHD) from a child psychiatry clinic.

It is subject to gender-norming and differential referral and diagnosis rates in girls versus boys, and, while highly heritable, is still stigmatized and labeled as “bad behavior” in many families.
