The diagnosis and treatment of ADHD in preschool children is both difficult
and controversial. Inattention, impulsivity, and hyperactivity-prominent f
eatures of ADHD are typical behaviors of most children in this age group. A
ggressive, noncompliant, and destructive behaviors may be reflective of tem
peramental characteristics, environmental stress, or poor parenting rather
than ADHD. Interdisciplinary assessment is often useful in sorting out vari
ous origins of problematic behavior. Stimulant medications have been shown
to be safe in young children but should be used conservatively, given the d
ifficulty in making the correct diagnosis. Parent counseling is a key compo
nent of treatment.
