Filter by:The purpose of this research is to assess and determine brain oscillations or "brain signatures" of adult participants with Attention Deficit Hyperactivity Disorder (ADHD) relative to adult participants without ADHD using the technique electroencephalogram (EEG). Electroencephalogram is entirely non-invasive way of tracking brain activity.The main goal of this study is to establish biological factors for determining the diagnosis of Attention Deficit Hyperactivity Disorder (ADHD).
The purpose of this study is to assess the relative feasibility of 2 potential functional measures of target engagement (Glx MRS, BOLD fMRI) to systematically assess mGluR 2/3 in drug development for psychotic spectrum disorders.
The purpose of this research study is to: Improve the effectiveness of vaccinations by identifying the effect of cholesterol medication, statins, on immune responses.
In this trial, fifty participants with current major depressive disorder who are not receiving an antidepressant medication and fifty healthy controls will complete questionnaires and computerized tasks to assess their decision-making styles. There will be three visits for depressed patients and two for healthy controls (the first and third visits). The first visit will involve interviews and questionnaires to assess the participant's level of depression, medical history and quality of life. Participants will then complete the decision-making tasks, and will earn between $5-40 based on their choices, in order to make the decisions on the computer tasks financially meaningful. At the completion of this visit, depressed patients will be prescribed an FDA-approved antidepressant, chosen in consultation with the treating psychiatrist. Patients will be responsible for paying for the prescription themselves. After two weeks on the medication, the patient will be seen for a follow-up visit to ensure tolerability of the medicine. After six weeks on the medicine, patients and healthy controls will return to repeat the questionnaires and the computer based decision-making tasks, and will again earn between $5-40 based on their performance.
This study aims to investigate whether two different measures of tactile acuity lead to comparable results in patients diagnosed with CRPS Type I of the upper extremity. Additionally patients with a neuropathy of the median nerve and healthy controls are included.
The purpose of this study is to investigate the effects of a combined training programme and a high intensity interval training programme on insulin resistance, muscle strength/ muscle contractile properties, aerobic capacity and body composition in MS patients. It is assumed that the the above mentioned clinical parameters will improve due to physical exercise.
Establish normative data of ElMindA's Brain Network Activation (BNA) using evoked response in three age groups.
This research is being done to look at the association between migraine and obesity.
Establish normative data of ElMindA's Brain Network Activation (BNA) using evoked response in two age groups: adolescents and young adults.
Concussed athlethes have discrete decreased abilities in motor learning. Recent research could further show, that cortical plasticity, as measured by transcranial magnetic stimulation (TMS) is reduced. This is possibly due to an increased GABAergic activity, what have been found in concussed athletes by paired pulse protocols in TMS. GABAergic acitivty can be modulated by transcranial direct current stimulation (tDCS) in a polar-specific manner: anodal tDCS was able to decrease GABA, whereas cathodal tDCS increased tDCS. Our study aimes to assess the influence of anodal tDCS on cortical plsticity in concussed athlethes. We hypothesize, that anodal tDCS is able to increase cortical plsticity in concussed athlethes.
