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…
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…
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 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 establish the pharmacokinetic profiles of saliva and plasma concentration of 10 mg MPH-IR and 18 mg MPH-OROS in healthy volunteers; to investigate whether there is a correlation between saliva- and plasma levels of MPH-IR and MPH-OROS, and if…
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…
The primary aim of our study will be to investigate the effectiveness of PCIT in comparison with methylphenidate in children with ADHD and disruptive behavior problems aged 2;6 till 6 years who have not responded sufficiently to previously offered…
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…
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.
