The study consists of two phases. In the first phase, we aim to investigate whether the dopamine receptor D4 (DRD4) genotype confers differential susceptibility to the effects of early life stress on empathy and prosocial behavior more generally in…
To replicate and extend the findings of the recent methylphenidate study in which methylphenidate was found to enhance episodic memory performance; To explore whether this effect of methylphenidate is primarily mediated by its dopaminergic action.
To investigate wether neo-adjuvant chemotherapy followed by cytoreductive syurgery and hyperthermic chemotherapy is feasible and reduces the number of irresectable patients with acceptable morbidity and mortality rates.
The primary objective of this study is to evaluate the efficacy of EN3348 as compared with mitomycin C in the treatment of subjects with BCG recurrent or refractory NMIBC.The secondary objective is to evaluate the safety of EN3348 as compared with…
to assess whether a single-dose of levodopa improves cognitive symptoms and balances goal-directed and habitual behavior.
In the present study, we aim to estimate concordance between two biomarkers developed to interrogate the presence of brain amyloid deposition. This includes a new amyloid PET-tracer, [18F]Flutemetamol, and a CSF biomarker The objective of the…
To investigate the effects of galantamine on cognitive impairment and visual hallucinations in Parkinson`s disease, both therapeutic (direct effect) and preventive (protection against an acute increase of dopaminergic medication used by the patient…
Primary objective:1. To investigate the clinical value of [18F]Flutemetamol PET in memory clinic patients and especially those with suspicion of young onset dementia in terms ofa. change in (level of confidence of) diagnosis;b. impact on patient…
The aim of this study is to improve our understanding of the mechanisms underlying altered social performance monitoring from a pharmacological perspective by directly comparing the effects of dopamine and oxytocin on individual and social…
The main objectives are to understand how clinical markers and biomarkers previously identified in younger and older AD cohorts apply to the extreme elderly (90+ years old) and to identify novel biomarkers linked with resilience to developing…
This is a medical-scientific research study. The purpose of the study is to investigate the effect of multiple doses of the study compound BIA 28-6156 on the pharmacokinetics of the drugs levodopa-carbidopa (Group 1) and levodopa-benserazide (Group…
To investigate whether early treatment with levodopa has a delayed beneficial effect on PD symptoms and functional health, and improves the ability to (maintain) work, reduces the use of (informal) care, caregiver burden, and costs. Additionally,…
The main objectives are to identify markers for amyloid pathology in cognitively normal subjects, to identify risk factors for amyloid pathology in cognitively normal subjects and to identify predictors for cognitive decline in cognitively normal…
The aim of this study is to evaluate the additional value of quantitative amyloid imaging analysis for modelling and assessing Alzheimer*s Disease (AD) dementia risk in individuals without dementia, compared to a range of existing cognitive, imaging…
