Scientific titleWorking memory in children with attention-deficit/hyperactivity disorder (ADHD): the impact of methylphenidate (MPH)
Study objectivesTo address the following questions: What are the effects of methylphenidate on working memory in children with ADHD? Is there evidence for differential effects of MPH on working memory function? What is the relationship between the effects of MPH on working memory, behavioural inhibition, non-executive memory performance and hyperactive/impulsive behaviour?
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedBehavioural disorders
Intervention1. Methylphenidate (MPH) treatment
2. No methylphenidate treatment
Intervention typeOther
Primary outcome measure1. Information about effects of MPH on cognitive function (including the possibility of cognitive toxicity) in children with ADHD
2. 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
3. Identification of potential cognitive deficits in ADHD. If persisting cognitive deficits are identified. These will be rational targets for supplementary treatment interventions
4. Suggestion of tests to monitor the effects of MPH on cognitive function which could be developed for use in everyday clinical practice.
