Description
Inclusion Criteria:
- Age 6 to 18 years
- Diagnosis of ADHD
- A score of at least 3 (mildly ill) on the clinician administered Clinical Global Impressions-Severity (CGI-S)
Exclusion Criteria:
- Currently taking stimulant medications (within one week of first study visit). Patients will not be asked to discontinue any treatments for the purpose of this research study. Subjects will include treatment naïve patients and patients who were previously treated with stimulant medications, but are not currently treated, and meet study criteria.
- Having an adverse reaction to methylphenidate, or other stimulant medication
- Current psychiatric disorder, including bipolar I or II disorder, major depressive, disorder, obsessive-compulsive disorder, autism spectrum disorder, Tourette syndrome, or history of psychosis
- Patient is at risk for clinically significant deterioration due to study protocol, as assessed by primary medical investigator (Dr. Grant)
- Confirmed genetic disorder with cognitive and/or behavioral disturbances
- Active, unstable medical illness that may interfere with cognition or compromises safety of the patient
- History of head trauma with loss of consciousness or any evidence of functional impairment due to, and persisting after, head trauma
- Neurological disorder, mental retardation, intellectual or disability, or other non-ADHD cause of cognitive impairment
- Pregnant or breast-feeding women
- Having a contraindication to MRI, including a pacemaker, defibrillator or other medical implant, other metal objects, or claustrophobia, or for having braces or other metal in the head region (likely to create an artifact on the MRI scans).
- Currently smoking or using controlled or illicit substances, including alcohol.

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
BOLD signal during response inhibition
Time Frame: Approximately 90 minutes after dose
|
Blood oxygenation level dependent (BOLD) signal (brain activity during functional magnetic resonance imaging (fMRI), arbitrary units) in the anterior cingulate cortex during response inhibition.
|
Approximately 90 minutes after dose
|
|
BOLD signal during working memory
Time Frame: Approximately 90 minutes after dose
|
BOLD signal (brain activity during fMRI, arbitrary units) in the frontal cortex during working memory
|
Approximately 90 minutes after dose
|
|
Glutamate level in the anterior cingulate cortex
Time Frame: Approximately 2 hours after dose
|
Glutamate level (measured by magnetic resonance spectroscopy (MRS), institutional units) in the anterior cingulate cortex (ACC).
|
Approximately 2 hours after dose
|
|
Glutamate level in the dorsolateral prefrontal cortex
Time Frame: Approximately 2 hours after dose
|
Glutamate level (measured by MRS, institutional units) in the dorsolateral prefrontal cortex
|
Approximately 2 hours after dose
|
|
Cognitive performance as assessed by the Flanker performance task
Time Frame: Approximately 3 hours after dose
|
NIH Toolbox Cognitive Battery Flanker task, score range 0 to 20, higher score is better performance
|
Approximately 3 hours after dose
|
|
Working memory performance
Time Frame: Approximately 3 hours after dose
|
NIH Toolbox Cognitive Battery working memory task (list sorting), score range 0 to 26, higher score is better performance
|
Approximately 3 hours after dose
|
Secondary Outcome Measures
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
ADHD as assessed by the Connors 3
Time Frame: At each study visit, approximately 3 hours after dose
|
Connors 3rd edition ADHD assessment, lower score means less symptoms, typical scores are 40 to 59, above 65 is an elevated score (meaning more concerns than are typically reported)
|
At each study visit, approximately 3 hours after dose
|
|
NIH Toolbox Cognitive Battery
Time Frame: Approximately 3 hours after dose
|
Cognition Fluid Composite, Cognition Crystallized Composite, Cognition Total Composite Score, and other individual test scores
|
Approximately 3 hours after dose
|
|
Methylphenidate plasma levels
Time Frame: Approximately 90 min and 150 min after dose
|
Methylphenidate plasma levels will be drawn before and after brain imaging on each visit
|
Approximately 90 min and 150 min after dose
