Provide proof-of-concept for the hypothesis that guanfacine diminishes cognitive side-effects in ER+ BC patients treated with adjuvant hormonal therapy. Secondary, provide data for power calculations in later studies.
The objective of this experiment is to establish the effects of tyrosine suppletion on cognitive symptoms seen in ADHD. Cognition will be assessed, while simultaneously recording brain activity.
Posner spatial cueing task will be used to investigate electrophysiological differences in brain oscillatory lateralization during attentional shifts in children with and without ADHD. We hypothesize that the observed difference in the ability to…
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.
To study whether the administration of oxytocin leads to stronger empathic responses on 3 different empathy-related tasks compared to a placebo.
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 aim of the study is to investigate the effects of atomoxetine on driving performance compared to placebo in 30 adult patients with ADHD. An auditory oddball paradigm will be presented and EEG will be measured during driving to gain insight in…
- 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…
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…
We aim to assess the effects of tyrosine supplementation on prefrontal brain activation, as measured by a combination of fNIRS and EEG, during response inhibition and working-memory performance in older adults. We will also assess whether…
We aim to develop a proxy-model of baseline dopamine based on machine learning methods which would provide us with behavioural predictors of the effects of dopaminergic drugs on brain and cognition that maximally generalize to new participants.
Primary objectiveTo assess whether the use of alimemazine improves symptoms of allergic diseases and ADHD, as scored by the parents using standardized questionnaires (Sample Snap IV rating scales)
The purpose of this study is to investigate how safe modafinil is and how well it is tolerated when it is administered in combination with aniracetam to generally healthy elderly volunteers with subjective cognitive decline. Modafinil and aniracetam…
Primary Objective: To determine the effectiveness of methylphenidate in reduction of ADHD symptomatology, operationalized by personalized goals that are important to the patient and its environment, in individuals with late-diagnosed PKU. Secondary…
The primary objectives are to investigate in older adults the effect of 16-week wild blueberry consumption on (regional) vascular function and insulin-sensitivity in the brain, while we will also focus on changes in cognitive performance as assessed…
The primary objective of this study is to unravel the effects of dopamine D2 receptor stimulation on gating of working memory, reinforcement learning, and reward-based motivation, and their associated physiological changes (measured with fMRI and…
The primary objective is to compare the pharmacological profile of the magistral form of dexamphetamine sulphate to the pharmacological profile of the brand-name form of dexamphetamine (Tentin©) in adult patients diagnosed with attention deficit…
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…
We will examine the cognitive performance of healthy young participants at different time points after a single administration of biperiden. The behavioural outcomes and electrophysiological correlates will be linked with the serum levels of…
