Multimodal Brain Imaging of the Neural Effects of Methylphenidate in Patients With ADHD
Who is this study for? Patients with attention-deficit/hyperactivity disorder
What treatments are being studied? Methylphenidate
Status: Recruiting
Location: See location...
Intervention Type: Drug
Study Type: Interventional
Study Phase: Phase 4
SUMMARY
The investigators' goal is to develop neuroimaging biomarkers to predict response to treatment with methylphenidate, which then can be used in the development of novel pharmacological treatments for attention-deficit/hyperactivity disorder (ADHD). The overall objective of this study is to measure the changes in task-related neural activity related to symptoms of ADHD (measured by functional MRI) and brain glutamate levels (measured by magnetic resonance spectroscopy, MRS) after treatment with methylphenidate (MPH). This will be a double-blind crossover of methylphenidate and placebo in adults with ADHD. Participants will complete neuropsychological testing along with fMRI and MRS scans after a single dose of each treatment.
