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…
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.
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…
