Neural Dynamics and Connectivity in Response Inhibition and Traumatic Brain Injury

Traumatic Brain InjuryStroke2 more

Background: - Previous research has shown that certain parts of the brain are involved in voluntarily stopping an ongoing motor response (movement); however, it is not known whether this same network is also involved in suppressing an urge to act. Traumatic brain injury (TBI) can significantly impair the brain's ability to voluntarily stop or inhibit certain actions. Using brain imaging (functional magnetic resonance imaging, or fMRI) and brain stimulation (transcranial magnetic stimulation, or TMS) to investigate how people perform activities that involve moving and suppressing movements, researchers hope to better understand how these brain areas might be affected in people who have had TBI. Objectives: To determine the parts of the brain involved in suppressing an urge to act. To determine the extent to which traumatic brain injury affecting certain parts of the brain is involved in problems with suppressing an urge to move and stopping movement. Eligibility: - Individuals 18 to 40 years of age who have had mild or moderate TBI, or are healthy volunteers. Design: This research study includes a screening visit and two study visits, each of which will last at least 2 hours. Participants will be screened with a physical examination and medical history. Women who can become pregnant will have a urine pregnancy test before being allowed to participate in the study. At the first study visit, participants will complete one of the following experiment tests in an MRI scanner. Experiment 1: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will practice the experiment tasks before performing them during MRI scans. Experiment 2: Participants will be shown arrows or images on a computer screen, and will press a button or not press a button depending on the image shown. Participants will also have TMS while at rest, and will perform the experiment tasks during the MRI scan. At the second study visit, participants will have an fMRI scan where they will be asked to do simple response tasks with a computer outside the MRI scanner.

Copeptin for Risk Stratification in Non-traumatic Headache in the Emergency Setting - The CoHead...

Head Pain

Headache is a common symptom, and patients often seek medical attention at emergency departments due to headaches. The aim of the CoHead Study is to find out if it is possible by measuring copeptin, a marker of stress in the blood, to find out which patients have simple headaches and which patients have dangerous headaches that are the symptom of an underlying disease and need further investigation and treatment. Copeptin is a marker for physical stress and has been tested in patients with stroke, heart attack and pneumonia. In all these illnesses, the patients with the most serious forms had the highest levels of copeptin, while the ones with only mild presentation or no affection at all had the lowest levels of copeptin. The investigators expect to show the same in patients with headaches.

Pain Quality Study

Low Back PainHeadache1 more

One way to better understand how various treatments for pain differ is to determine the effects of these treatments on different pain qualities or characteristics. For example, pain can be described as "hot", "electrical", "cold", "achy", and "piercing." In order to determine which pain quality/qualities that a pain treatment affects, researchers must develop measures of these pain qualities or characteristics. The purpose of this study is to learn more about the different pain qualities individuals who have low back pain, headaches and fibromyalgia experience. Identifying the common qualities of pain experienced by these groups will help researchers evaluate and develop more comprehensive pain quality measures, which will ultimately help them to be able to test the effectiveness of treatments for these different pain qualities.

Adrenomedullin Effect on Migraine Without Patients

HeadacheMigraine

AM is a naturally occurring peptide in the body and consists of 52 amino acids. AM belongs to the calcitonin gene-related peptide (CGRP) superfamily and has several structural, physiological and pharmacological similarities to CGRP, intermdine and amylin. In a randomized double-blind, placebo controlled cross-over design 20 migraine patients without aura recruited to receive infusion of adrenomedullin or placebo (saline).

Sphenopalatine Ganglion Block for Postdural Puncture Headache

Postdural Puncture Headache

Background: Postdural puncture headache (PDPH), which is one of the complications of spinal anesthesia, is a condition that negatively affects the quality of life of patients, causes late mobilization and prolonged hospital stay. Sphenopalatine ganglion block (SGB) has created a minimally invasive, easy, and safe treatment alternative. Objective: Evaluating the effectiveness of topical SGB on PDPH treatment. Design: Retrospective observational study Setting: Single center tertiary level of care hospital study. The files of PDPH patients between Jan 2018 and Jan 2020 were scanned. Patients: PDPH patients aged 18-65 are included and any patients with primary/secondary headache history are excluded. Main outcome measures: Patients were divided into 2 groups. The group that given only conservative treatment was named as Group C, and the group of patients who had additionally been applied SGB was named as Group SGB. Headache severity was measured with Visual Analogue Scale (VAS) at the 1st,3rd, 12th and 24th hours of the treatment, in supine and upright position.

Effectiveness of Acupuncture Clinical Pathway

Chronic PainLumbar Back Pain6 more

The study will be described the development and implementation of the Clinical pathway (CPW) for acupuncture treatment in the management of patients with some chronic pain conditions. The effectiveness of this CPW will be explored in this study through retrospective analysis of clinical outcomes after administration of acupuncture treatment summarised in the guidelines.

Headache Provocation of People Who Are Unable to Have Headache

HeadacheHealthy

Headaches are extremely common illnesses with a combined lifetime prevalence of 90-99% in Europe. Despite this high prevalence, there are persons who have never, in their whole life, encountered a headache. The aim of the study is to identify factors that protect against headache by studying headache after provocation in people who never have had a headache (headache resistant) versus non-resistant controls. The investigators will use isosorbide mononitrate as a pharmacological trigger of headache. The provocation is performed by investigators who are blinded to the grouping of the participants. The investigators hope to contribute with novelty to the current understanding of headache pathophysiology and development of more efficient treatment of headache.

Multiomics After Cold Pressor Test of People Who Are Unable to Have Headache

HeadacheHeadache Disorders1 more

Headaches are extremely common illnesses with a combined lifetime prevalence of 90-99% in Europe. Despite this high prevalence, there are persons who have never, in their whole life, encountered a headache. The aim of the study is to identify factors that protect against headache by studying multiomics in people who never have had a headache (headache resistant) versus non-resistant controls. The investigators will measure multiomic changes (transcriptomics and metabolomics) after pain induction by Cold Pressor Test. 3 blood samples, two for RNA and one for metabolites are taken 5 minutes before a Cold Pressor Test and again 1 hour after the Cold Pressor Test. The investigators hope to contribute with novelty to the current understanding of headache pathophysiology and development of more efficient treatment of headache.
