Trial Title: The Effects of ADHD Medication (TEAM) Study

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: QUADRUPLE
- Phase: PHASE4
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~1. ADHD Diagnostic Status: Meets DSM-V criteria for ADHD, with Clinical Global Impression (CGI) rating corresponding to at least moderately ill.~2. Cognitive and Academic Functioning: Intelligence Quotient (IQ) of \>80 as estimated by Vocabulary and Block Design subtests of the Wechsler Intelligence Scale for Children-4th Edition and scaled scores \>80 on the Wechsler Individual Achievement Test-2nd edition Reading and Math subtests~3. Physical Health: Physical exam and ECG findings are judged to be normal for age and sex by study physician and/or medical consultant, and there is no co-existing condition for which MPH is contraindicated 4. School: Enrolled in a school setting rather than a home-school program. This ensures that we can obtain parent and teacher ratings from separate individuals for diagnosis and outcome assessment~Exclusion Criteria:~1. Psychiatric Medications: Current or prior use of any medication for psychological/psychiatric problems~2. Behavioral Interventions: Current active participation in ADHD-related behavioral interventions, given that improvements due to these interventions may confound our group comparisons~3. Psychiatric or Neurobehavioral Conditions: Children with mania/hypomania, schizophrenia, or severe depressive disorder, as determined by the K-SADS, will be excluded since ADHD medications may not be an appropriate first line of treatment for children with these comorbid disorders~4. Organic Brain Injury: History of head trauma, neurological disorder (including epilepsy), or other disorder affecting brain function due to potential differences in neurophysiology of ADHD phenotype~5. Cardiovascular Risk Factors: Children with a personal history or family history of cardiovascular risk factors will be excluded, or given the option of participating in the study after obtaining an EKG and verification from a pediatric cardiologist regarding the safety of their participation in a trial of methylphenidate. In this case, families will be responsible for the costs of EKG and any necessary cardiologist evaluation~6. Pregnancy: The safety of MPH use during pregnancy has not been established

Study Arms:
- MPH Discontinuation (Type: PLACEBO_COMPARATOR): 1. Double-blind (DB) placebo-controlled 4-week methylphenidate (MPH) titration trial. Pts will receive 3 active dosages of MPH (children \<25kg: 18mg, 27mg, 36mg; children \>25kg: 18mg, 36mg, 54mg for) as well as 1 random week of placebo, given qAM. Pts will begin on the lowest dose (or a randomized placebo week) and proceed through all dose conditions in an incremental fashion.~2. DB 4-week MPH maintenance phase. The clinician, parent, and teacher ratings of behavior and side effects from the titration trial weeks will be graphed. Two doctors will blindly review the graphs and judge which week was the optimal dose week. Pts will then receive their optimal dose of MPH (qAM) for 4 weeks.~3. DB 4-week MPH Discontinuation Phase. Pts in this arm will receive placebo (qAM).
- Sustained MPH (Type: ACTIVE_COMPARATOR): 1. Double-blind (DB) placebo-controlled 4-week methylphenidate (MPH) titration trial. Pts will receive 3 active dosages of MPH (children \<25kg: 18mg, 27mg, 36mg; children \>25kg: 18mg, 36mg, 54mg for) as well as 1 random week of placebo, given qAM. Pts will begin on the lowest dose (or a randomized placebo week) and proceed through all dose conditions in an incremental fashion.~2. DB 4-week MPH maintenance phase. The clinician, parent, and teacher ratings of behavior and side effects from the titration trial weeks will be graphed. Two doctors will blindly review the graphs and judge which week was the optimal dose week. Pts will then receive their optimal dose of MPH (qAM) for 4 weeks.~3. DB 4-week MPH Discontinuation Phase. Pts in this arm will continue their optimal MPH dose (qAM).
