OBJECTIVE To investigate growth of children with attention-deficit/hyperactivity disorder (ADHD) in the Preschool ADHD Treatment Study (PATS) before and after initiation of treatment with methylphenidate at titrated doses (average, 14.2 mg/day) administered three times daily, 7 days/week for asymptotically equal to1 year. METHOD The heights and weights of(More)
OBJECTIVE To report on the safety and tolerability of methylphenidate (MPH) 3- to 5-year-old children with attention-deficit/hyperactivity disorder (ADHD) during 1 year of treatment. METHOD Exactly 183 children (3-5 years old) entered a treatment study of MPH, consisting of a 1-week open-label lead-in (n=183); a 5-week placebo-controlled, double-blind(More)
OBJECTIVE The aim of this study was to compare the pharmacokinetics of immediate-release methylphenidate (MPH) in preschool and school-aged children with attention-deficit/hyperactivity disorder (ADHD). METHODS Preschool children 4-5 years (n = 14) and school-aged children 6-8 years (n = 9) with diagnoses of ADHD were titrated to an effective dose of MPH(More)
OBJECTIVE To evaluate the hypothesis of stimulant medication effect on physical growth in the follow-up phase of the Multimodal Treatment Study of Children With ADHD. METHOD Naturalistic subgroups were established based on patterns of treatment with stimulant medication at baseline, 14-, 24-, and 36-month assessments: not medicated (n = 65), newly(More)
OBJECTIVE To describe the clinical course of attention-deficit/hyperactivity disorder (ADHD) symptom severity and diagnosis from ages 3 to 5 up to 9 to 12 years during a 6-year follow-up after the original Preschool ADHD Treatment Study (PATS). METHOD A total of 207 participants (75% male) from the original PATS, assessed at baseline (mean age, 4.4 years,(More)
OBJECTIVE To compare educational, occupational, legal, emotional, substance use disorder, and sexual behavior outcomes in young adults with persistent and desistent attention-deficit/hyperactivity disorder (ADHD) symptoms and a local normative comparison group (LNCG) in the Multimodal Treatment Study of Children with ADHD (MTA). METHOD Data were collected(More)
OBJECTIVE To pilot the novel use of 2 existing laboratory school measures--the Permanent Product Measure of Performance (PERMP) and the Grammar Task--as provoking stimuli of stress, and to observe the effects of medication and stress on children with attention-deficit/hyperactivity disorder (ADHD). METHODS Children received individually determined optimal(More)
OBJECTIVE Longitudinal studies of children diagnosed with ADHD report widely ranging ADHD persistence rates in adulthood (5-75%). This study documents how information source (parent vs. self-report), method (rating scale vs. interview), and symptom threshold (DSM vs. norm-based) influence reported ADHD persistence rates in adulthood. METHOD Five hundred(More)
OBJECTIVE The purpose of this study was to assess the time of onset and time course of efficacy over 12.0 hours of extended-release multilayer bead formulation of methylphenidate (MPH-MLR) compared with placebo in children 6-12 years of age with attention-deficit/hyperactivity disorder (ADHD) in a laboratory school setting. METHODS This randomized(More)
OBJECTIVE To evaluate the type, frequency, duration, and severity of treatment emergent adverse events (TEAEs) of the prodrug lisdexamfetamine dimesylate (LDX) in children with and without previous exposure to stimulant medication in the treatment of attention-deficit/hyperactivity disorder (ADHD). METHODS This single-blind, modified laboratory school(More)
