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…
The primary objective of the proposed study is to investigate whether bumetanide therapy indeed reduces autistic symptomatology. Important secondary goals of this project are to determine whether bumetanide will improve specific behavioral,…
To study the effect of a nerve block of the infrapatellar nerve with local infiltration with lidocaine or saline on chronic anterior knee pain after tibial nailing.Secondairy objectives:- to measure knee pain on a VAS for eight different activities…
1. We want to study the success rate of OAHM withdrawal in patients with chronic migraine related to support by a headache nurse, and onabotulinum toxin A injections during the withdrawal period, and the influence of comorbid depression.2. We want…
We hypothesize that PD patients with dopa-responsive and dopa-resistant tremor have different tremor-related brain activity, different inter-regional functional connectivity, and different GABA-ergic tone in the thalamus. Furthermore, we expect that…
The primary objective of this proof of principle study is to determine the effect of levosimendan on the strength and endurance of the diaphragm in healthy subjects. The secondary objective is to gain insight in the neural activation and efficiency…
To investigate if jerks and psychiatric disorders in patients with dystonia are associated with a hyperdopaminergic/ hyposerotonergic system and whether reversal of a hyposerotonergic state has a therapeutic effect.
To investigate cerebral activation patterns after administration of an AChE-I (rivastigmine), compared to activation after placebo, in PD patients with VH.Secondly, to investigate whether cerebral activation changes after rivastigmine correlates…
A. What are possible causes of MP and what patients variable are asssociated with MP. What is the natural course and prognosis of MP. What is the influence of MP on the quality of life.B. What is the diagnostic value of SSEP en nerve conduction…
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…
We hypothesize that PD patients with and without tremor have different patterns of midbrain structural integrity in (dopaminergic) nuclei, different patterns of functional connectivity from midbrain to basal ganglia, differences in GABA-ergic tone…
The primary objective of the study is to test the effectiveness of bumetanide across the whole spectrum of sensory processing disorders within ASD, ADHD and/or epilepsy. We also want to determine which subgroups (high/low IQ, comorbidities or not)…
I will test the hypothesis that the noradrenergic system amplifies tremulous activity in the cerebello-thalamo-cortical circuit. More specifically, I will test how this modulation takes place (i.e. through which brain regions and connections).
This study has been transitioned to CTIS with ID 2024-520305-39-00 check the CTIS register for the current data. Primary objective: to evaluate the efficacy of LSD 25µg every 3 days for 3 weeks in cCH. Additional objectives:- To evaluate the safety…
To determine differences in brain activation and networks in alcohol responsive essential tremor versus alcohol resistant essential tremor.
The overall aim of this study is to gain insight into the pathophysiological mechanism of patients with non- specific neck pain and cervical radiculopathy and the influence of MP on these mechanisms. Therefore, different research objectives are…
Primary Objective: To investigate the effect on the distention of the ONSD while using lidocaine 1,5 mg/kg IV during endotracheal intubation versus placebo. Secondary Objectives: The secondary objective of this study is to investigate the effect…
To provide an answer to the following questions: 1. In patients with AD, does treatment with a ChEI improve cerebral hemodynamics? 2. Is there less progression of cerebrovascular lesions on follow-up of AD patients receiving ChEI*s? 3. Does this…
The main aim of this study is to assess hypothesis A, and we will perform an exploratory analysis on hypothesis B.
