Official title
Effects of Lisdexamfetamine on Cognitive Control and Reward Response in Adolescents and Young Adults With ADHD: Neural and Clinical Outcomes
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to identify the effects of lisdexamfetamine (LDX) on the neural and behavioral subcomponents of self-control, that is cognitive control and reward functioning, in adolescents and young adults with attention-deficit/hyperactivity disorder. The investigators hypothesize that LDX is associated with 1a) decreased task-independent locus coeruleus (LC) activity; 1b) increased task-related activity in LC and the cognitive control network; 2) increased LC connectivity with the cognitive control network and 3) improved task performance and self-control. The investigators will test their hypotheses on fMRI data with linear contrasts of voxel-wise maps of parameter estimates (in both univariate and connectivity analyses). The investigators will also assess change in brain activity with the LDX in the LC and ventral tegmental areas (VTA) as we hypothesize that they are altered in ADHD and related to cognitive control and self-control dysfunction in ADHD. The investigators will use a repeated-measures, between-subject design to compare the effects of oral once daily LDX in a double-blind placebo-controlled randomized trial (RCT) on neural (fMRI) and behavioral correlates of cognitive control via a working memory and a reward - delay discounting task in adolescents and young adults. A new condition has been added which will use a within-subject comparison, cross-over design between a single dose of LDX versus a single dose of placebo.
