Commentary: Who gets the credit for "discovering" ADHD and what is the question, really?

Recognition of hyperactivity, impulsivity, distractibility, and emotional lability as a clinical syndrome is at the heart of identifying whether there is a discoverer of the condition of attention deficit hyperactivity disorder (ADHD). Just as clinics of children diagnosed with ADHD do not capture a homogeneous group of boys and girls, however, history does not either. What different observers/clinicians have chosen to highlight reflects what is important to them and to the times in which they lived. The child/children described by Heinrich Hoffman (of Fidgety Phil fame) and George Still (who highlighted impulsive aggression as a moral defect), for instance, did not come with a list of criteria (with which even now we cannot always agree) to prove unequivocally that they had ADHD. Who cares! It is sufficient that they recognized the importance of certain co-occurring behaviors and shared their observations with us such that we can conclude our clinic's children were recognized by good past observers. ADHD-like children, like the poor, have probably always been with us.
