Psychotropic medication treatment of attention deficit hyperactivity disord
er (ADHD) has prominently increased over the last three decades such that a
n estimated 2 to 2.5 million youths in the United States now receive this t
reatment. Stimulants have been and remain the primary prescribed medication
group to treat this disorder, even though the variety of medication treatm
ents has expanded in recent years. The major reasons for the increased prev
alence of stimulant treatment are: increases in the diagnostic pool-particu
larly the inclusion of more youths with predominantly inattentive ADHD; the
great number of girls receiving this medication; increases in the duration
of treatment; and a greater public acceptance of the psychopharmacologic t
reatment of youth. Demographic factors, school placement, geographic locati
on, service system differences, and the specialty of the treating physician
all influence the prevalence of medication treatment, and the impact of th
ese factors will be described. Briefly reviewed at the conclusion are the u
se of non-stimulant medication treatments, multiple and concomitant medicat
ion treatments for ADHD, and international differences in prescribing patte
