To investigate acute effects of a single 40 mg dose hydrocortisone, compared with placebo, on stress and various aspects of attention and other cognitive processing of emotionally relevant stimuli in healthy anxious young females. The main question…
The primary objective of this pilot study is to determine the effectiveness of four treatment options for local skin reactions induced by continuous subcutaneous apomorphine infusion, as compared to no treatment.The primary endpoint is the measured…
Primary:1. To establish the effect of MCP on the release of plasma AVP and subsequent ACTH and cortisol secretion in the absence of a 5HTP-challenge.2. To establish the effect of MCP on the release of plasma AVP and subsequent ACTH and cortisol…
The objective of this study is to assess the effects of an increased NE level on the trade-off between exploitation and exploration. More specifically, this study will compare the exploitative/explorative behavior of participants who received either…
Primary Objectives:- To investigate the effects of a single dose (plasma concentration) 5-HTP challenge test (5-HTP200mg/CBD100+50mg/granisetron2mg) on hypothalamic fMRS activation patterns in healthy male volunteers.Secondary Objectives:- To assess…
We propose to conduct a study in healthy young and elderly subjects and patients diagnosed with mild to moderate AD, FTLD, or DLB where cholinergic and serotonergic challenges are given in a placebo-controlled, crossover fashion. Before each…
The aim of this study is to investigate whether a physiologically low hydrocortisone (HC) dose is better for cognition as compared to a high hydrocortisone dose. In addition, quality of life, metabolic profile and somatosensation will be described…
We propose to conduct a study in healthy subjects where a serotonergic challenge is given in a placebo-controlled, crossover fashion. Before each challenge, participants will be measured 1 time to define their baseline resting state networks (RSNs)…
To study the effects of 2 standard treatment timing strategies for glucocorticoid dosage on androgen concentration in CAH children: a. highest dosage in the morning, b. highest dosage in the evening.
Objectives: To test the hypothesis that the thyroid gland of offspring of long-lived siblings is more resistant to stimulation with TSH compared to the thyroid gland of their partners, offspring and partners will receive a low dose of recombinant…
The purpose of this research study is to compare the safety and effectiveness of Chronocort® with current glucocorticoid treatment regimens in the treatment of CAH over a 6 month period.
Investigate whether a low-dose of hydrocortisone (cortisol) reduces neuropsychiatric symptoms in glioma and meningioma patients who are perioperatively treated with a high dose of the synthetic glucocorticoid dexamethasone, compared to patients…
REMAP-CAP: The goal of the study is to investigate the best treatment regime for pneumonia patients. For non-pandemic pneumonia (including Influenza) we investigate this in critically ill patients. For pneumonia caused by SARS-CoV-2, we investigate…
The primary aim is to validate the finding that addition of physiological doses of hydrocortisone reduces dexamethasone-induced clinically relevant neurobehavioral problems. The secondary aims are to study the role of genetic variation, psychosocial…
Substudy A: The primary objective will be to investigate the relationships between HPA axis dysfunction, early life adversity (ELA), and epigenetic mechanisms. Furthermore, this substudy will function to select participants for substudy B. Secondary…
