Objective To report on implications for methylphenidate treatment of this very young age group and the need to examine factors related to achieving compliance. Method Thirty-one children with attention-deficit hyperactivity disorder (ADHD), aged 4 to 6 years, participated in a double-blind, placebo-controlled study using placebo, 0.3 mg/kg, and 0.5 mg/kg of methylphenidate twice per day. Results Improvements related to medication were obtained on cognitive tests of attention and impulsivity as well as behaviors assessed by parent rating scales. In an interactive setting with their mothers, attentional abilities and the children's ability to work more productively also showed improvement. However, no changes were obtained with respect to the children's tendency to comply with parental requests. Side effects increased slightly with the high dosage of medication but remained mild. Conclusion The results suggest that methytphenidate can be used to improve the functioning of preschool-age children with ADHD, in a manner similar to their school-age counterparts.
