To replicate and extend the findings of the recent methylphenidate study in which methylphenidate was found to enhance episodic memory performance; To explore whether this effect of methylphenidate is primarily mediated by its dopaminergic action.
Primary Objective:The primary objective in the current trial is to use graph theory to examine how the organization of the functional brain network may be altered by the administration of methylphenidate. The main question we intend to answer in…
Primary objective of the study: 1. To report on the effectmodification by age of MPH treatment on the outgrowth of the DA system using state-of-the-art Magnetic Resonance Imaging (MRI) techniquesSecondary objectives:1. To report on the…
Primary Objective: To study the change on performance on executive function and memory function (as measured on Neurocart), after an active challenge with methylphenidate (monoaminergic) and galantamine (cholinergic), compared to placebo, in…
We aim to examine, in the impaired older population, whether a treatment using methylphenidate, a DA re-uptake inhibitor that enhances DA, improves attention and memory.
Primary objective: To investigate the effectiveness of ongoing treatment with methylphenidate as prescribed in clinical practice beyond two years in children and adolescents. Secondary objectives:(1) to investigate the effects of discontinuation of…
Primary:The primary objective of this study is to evaluate the efficacy of LDX administered as a daily morning dose (30, 50, and 70mg/day) compared to placebo over the course of 7 weeks. This study will enrol children and adolescents (6-17 years of…
The objectives of this study are to establish whether methylphenidate PD effects can be measured using neurocognitive tasks, to describe the drug concentrations of methylphenidate in saliva, to describe the PK/PD relationship using the obtained…
The primary objective of this study is to evaluate the dose response, dose interval, efficacy, and safety of GSK961081 by studying three QD doses and three BID doses in subjects with COPD. The study will also evaluate the population PK, systemic PK-…
- short-term efficacy of MPH on ADHD symptomatology in adult male SUD patients with ADHD.- short-term influence of MPH on abstinence and drug use- short-term influence of MPH on cocaine craving - safety and adverse effects of MPH in this patient…
With intervention with bronchodilators (usual care bronchodilators for COPD subjects), in one study histamine and in one study steroids, we want to investigate the respons on inspiratory lung function parameter like the FIV1 and also investigate…
The objective of this project is to study the role of dopaminergic mechanisms in apathy, mood and HDD in patients with PD. What is the involvement of the dopaminergic neurotransmitter system in motivation and reward processes in PD and the clinical…
The main objective of this study is to compare the acute effects of methylphenidate on behavioral and cognitive functioning in 6 to 12 year old treatment naïve children compared to the effects after nine months of treatment with methylphenidate in…
The primary objective is to determine the efficacy of methylphenidate on ADHD symptoms in Smith Magenis syndrome.The secondary objectives include the efficacy of methylphenidate on emotion dysregulation and specific goals that are important to the…
The aim of this project is to investigate associations between visual system functioning, ADHD, and the circadian rhythm. We will also investigate the effects on the functioning of the visual system of commonly used treatments for ADHD and related…
