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: 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.
1) To investigate if it is possibility to measure neural activation (CBF) in the DA brain stem nuclei and the functionally associated brain regions with ASL. 2) To investigate the effect of increased DA on activation in the DA system during resting…
Determine the influence of methylphenidate treatment on sleep-wake rhythm and endogenous melatonin rhythm.
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 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…
To investigate whether impairments of shifting between response sets underlie motor freezing in PD and to investigate the efficacy and the neural mechanism by which MPH improves gait and cognition in PD patients with FOG.
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…
To assess the effect of dupilumab on sleep, to evaluate the effect of dupilumab on additional patient reported sleep outcomes, on objective sleep assessment, asthma symptoms, long function and the safety of dupilumab.
Main study:To evaluate the efficacy of dupilumab in patients with inflammatory subtypes of severe chronic hand eczema with an inadequate response or intolerance to alitretinoin and in patients with concomitant positive patch test results.Substudy:…
- The purpose of this study is to evaluate the efficacy of the study drug to lung function, exacerbations and quality of life with patients with COPD. The safety and tolerability of the study drug is monitored as part of this study.
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…
