OBJECTIVE To examine lisdexamfetamine dimesylate (LDX) efficacy and safety versus placebo in adolescents with attention-deficit/hyperactivity disorder (ADHD). METHOD Adolescents (13 through 17) with at least moderately symptomatic ADHD (ADHD Rating Scale IV: Clinician Version [ADHD-RS-IV] score ≥28) were randomized to placebo or LDX (30, 50, or 70 mg/d)(More)
OBJECTIVE To evaluate lisdexamfetamine dimesylate maintenance of efficacy in adults with attention-deficit/hyperactivity disorder (ADHD). METHOD Adults (aged 18-55 years) who had ADHD meeting DSM-IV-TR criteria, baseline ADHD Rating Scale-IV (ADHD-RS-IV) with adult prompts total scores of < 22, and Clinical Global Impressions-Severity of Illness (CGI-S)(More)
BACKGROUND Lisdexamfetamine dimesylate (LDX) is indicated for the treatment of attention-deficit/hyperactivity disorder (ADHD) in children 6 to 12 years of age and in adults. In a previous laboratory school study, LDX demonstrated efficacy 2 hours postdose with duration of efficacy through 12 hours. The current study further characterizes the time course of(More)
This study evaluated the efficacy and safety of lisdexamfetamine dimesylate (LDX) compared with placebo in children and adolescents with attention-deficit/hyperactivity disorder (ADHD) in Europe. Osmotic-release oral system methylphenidate (OROS-MPH) was included as a reference arm. Patients (6-17 years old) with a baseline ADHD Rating Scale version IV(More)
BACKGROUND Duration of efficacy and safety of lisdexamfetamine dimesylate (LDX) was assessed in adults (18-55 years) with attention-deficit/hyperactivity disorder (ADHD) using the simulated adult workplace environment. METHODS After open-label dose optimization (4-week) with LDX, 30-70 mg/d, subjects entered a 2-week randomized, double-blind,(More)
BACKGROUND In classical lissencephaly, the cerebral cortex is four-layered, containing neurons that have failed to complete their migration between 12 and 16 weeks of gestation. METHODS The authors studied the functional activity of lissencephalic cortex using 2-deoxy-2[(18)F]fluoro-D-glucose PET (FDG PET) in eight patients (six girls and two boys, mean(More)
INTRODUCTION There are limited head-to-head data comparing the efficacy of long-acting amfetamine- and methylphenidate-based psychostimulants as treatments for individuals with attention-deficit hyperactivity disorder (ADHD). This post hoc analysis provides the first parallel-group comparison of the effect of lisdexamfetamine dimesylate (lisdexamfetamine)(More)
Lisdexamfetamine dimesylate (LDX) is a long-acting, prodrug stimulant therapy for patients with attention-deficit/hyperactivity disorder (ADHD). This randomized placebo-controlled trial of an optimized daily dose of LDX (30, 50 or 70 mg) was conducted in children and adolescents (aged 6-17 years) with ADHD. To evaluate the efficacy of LDX throughout the(More)
A 7-year review at our institution identified 12 children with midbrain tectal tumors. All presented with signs of increased intracranial pressure, had hydrocephalus on initial imaging, and were treated with ventriculoperitoneal (VP) shunts. Three had clinical and radiographic progression of disease. Two were treated with radiation and chemotherapy, with(More)
BACKGROUND Optimal management of attention deficit hyperactivity disorder (ADHD) aims not only to ameliorate patients' symptoms, but also to improve health-related quality of life (HRQL) and functioning. A pivotal, 7-week, randomized, double-blind, placebo-controlled, phase III study in children and adolescents in ten European countries demonstrated that(More)
