Children with ADHD and motor dysfunction compared with children with ADHD only.

The purpose of this study was to identify group differences in children with attention-deficit-hyperactivity disorder and motor dysfunction (ADHD-MD) and ADHD only, and to evaluate the medication responsiveness of ADHD-MD. Sixty-three children (49 males and 14 females; mean age 9 years 10 months, SD 2 years 10 months) underwent a triple blind, placebo-controlled crossover study evaluating two dose levels of methylphenidate (0.3 mg/kg and 0.

A retrospective study of children's perceptions of participation as clinical research subjects in a minimal risk study.

The purpose of the study was to evaluate children's perceptions of their participation as research subjects in a minimal risk research study (a methylphenidate population pharmacokinetic study conducted 8 months earlier). We identified 115 children of an original 189, aged 6 to 19 years, who were responding well to regular methylphenidate for attention-deficit hyperactivity disorder. By using a structured format, telephone interviewers unconnected to the original study questioned the children about what it had been like to be a subject in terms of voluntariness, accuracy of informed consent, reasons for participating, and satisfaction with their experience.

Effectiveness of methylphenidate in Native American children with fetal alcohol syndrome and attention deficit/hyperactivity disorder: a controlled pilot study.

This pilot study was designed to assess the short-term effectiveness and side effects of methylphenidate in treating symptoms of attention deficit hyperactivity disorder (ADHD) in Native American children (5 to 12 years old) with documented fetal alcohol syndrome (FAS) or partial fetal alcohol syndrome. Using strict criteria for the diagnosis of FAS and ADHD, a randomized double-blind cross-over study of two placebos and a fixed dose of methylphenidate was completed in 4 Native American children in a residential school. Each treatment condition lasted 5 days, and daily observational outcome measures, the Conners Parent Rating Scale (CPRS-48), and the Conners Teacher Rating Scale (CTRS-39), were employed.
