| Status of trial | Completed |
| Target number of participants | 60 |
| Interventions | i. Methylphenidate (MPH) treatment ii. No methylphenidate treatment |
| Primary outcome measure(s) | Provision of information about effects of MPH on cognitive function (including the possibility of cognitive toxicity) in children with ADHD; Provision of greater understanding of the underlying cognitive processes in ADHD. This knowledge of underlying mechanisms will lead to improved specificity of early detection, diagnosis and treatment of ADHD; Identification of potential cognitive deficits in ADHD. If persisting cognitive deficits are identified. These will be rational targets for supplementary treatment interventions; Suggestion of tests to monitor the effects of MPH on cognitive function which could be developed for use in everyday clinical practice. |
