Description of intervention(s) / exposure
Once Baseline testing is completed, ADHD subjects will be dosed with short-acting methylphenidate as per local/country standard of care. Therefore, the length of treatment will differ and is based on the subjects response.
Baseline testing consists of a clinical interview and medical history, a pregnancy test (for females of childbearing potential), web-based questionnaire, psychophysiology data collection, touchscreen cognitive testing, saliva collection for Deoxyribonucleic acid (DNA) analysis. A urine sample may be requested to rule out current illicit drug use. Structural and Functional Magnetic Resonance Imaging (MRI) will be performed at selected sites and in 10% of subjects. This part of the baseline assessment is optional.
Baseline testing is expected to take up to 7 hours and may be completed over 2 days.
Recommended Dosage: 5 mg twice daily given as oral tablets with gradual increments of 5 to 10 mg weekly. Daily dosage above 60 mg is not recommended.

Outcomes
Primary outcome [1]
5610
0
Composite markers from 165 different assessments/variables will be assessed to identify genetic, brain structure/function and cognitive markers (or combination of markers) which predict acute drug treatment response in ADHD. This will be assessed using: The MINI International Neuropsychatric Interview for Children and Adolescents, ADHD Rating Scale IV, Conners Rating Scales - Revised (Long versions - parent and teacher). Web based questionnaire (web-Q), including: Brain Resource Inventory of Social Cognition (BRISC), Depression, Anxiety and Stress Scale (DASS21), Neuroticism, Extraversion, and Openness Five Factor Inventory (NEO-FFI), Paediatric Quality of Life Inventory (PEDS-QL). Psychophysiological assessment (including, respiratory rate, sweat rate, Electroencephalography (EEG) and Event Related Potential) and a Cognitive test battery. Genetic analysis. Structural and functional magnetic resonance imaging (MRI).
