Treatment of Preschoolers with Attention-Deficit/Hyperactivity Disorder

This article reviews the current treatment literature for attention-deficit/hyperactivity disorder (ADHD) in preschoolers. Parent training studies show consistent behavioral improvements reported by teachers and observers as well as parents, with evidence of clinically significant improvement in ADHD symptoms for up to 2 years. Few other behavioral interventions have been evaluated, although data from a large psychosocial, multimodal intervention are forthcoming. There is evidence to support the benefit of immediate-release stimulant medication for up to 1 year; however, effects do not seem to be as large, and some of the side effects may be greater than for school-age children. With regard to nonstimulants such as atomoxetine, there are literally no controlled outcome data for children with ADHD who are younger than 5 years of age. Overall, a great deal remains to be learned about the safety and efficacy of pharmacotherapy in this age group. Fortunately, results of several large intervention studies will be available soon to better inform clinical practice.
