NCT01194661
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.

NCT01905748
Acute Migraine attacks can be related to vascular or coagulation activation. Previous studies found relative high incidence of prothrombotic events in Migraine. The present study intends to assess the coagulation system and activation in patients with Migraine during steady state phase and at the beginning of attacks and after 72 hours. A control group of patients with another acute neurologic event like convulsions will be also studied. Patients will be at pediatric age and teenagers.

NCT03550586
Epidural analgesia is considered a gold standard method for treatment of labor pain. One of the major risks with epidural analgesia is an accidental dural puncture, which leads to a post dural puncture headache. This headache is associated with significant maternal morbidity and can result in severe maternal consequences. Post traumatic stress disorder (PTSD) is defined as an anxiety syndrome, resulting from a traumatic experience. Postpartum PTSD, is a form of PTSD that can occur in relation to a traumatic birth experience. As PDPH is unexpected and can cause severe maternal sequele, PDPH can exhibit a posttraumatic stress response. Therefore we hypothesize that parturients who suffered from a PDPH are at higher risk for developing PP-PTSD. To date, very few reports have examined the long term outcomes of parturients suffering from a PDPH. As a follow up to the national survey of PDPH management in Israel the investigators aim, in this prospective multi center, observational study, to evaluate the long term outcomes of parturients suffering from a PDPH, including chronic headache, backache, postpartum depression, decreased breastfeeding and the development of PP PTSD.

NCT03133884
Two hundred and eighteen patients with chronic tension-type headache(CTTH) will be randomly assigned to an experimental group (acupuncture) and a control group (superficial acupuncture) in a 1:1 ratio. Participants in both groups will receive 20 sessions of acupuncture over 8 weeks, and the same acupoints will be selected in acupuncture treatments.The study cycle will last 36 weeks, including a 4-week baseline period, a 8-week treatment period and a 24-week follow-up period. And the primary outcome will be measured at the end of 16th week. While, the secondary outcomes will be measured at the baseline, the 4th, 8th,12th,16th,20th,24th,28th and 32nd week after randomization.After each treatment, participants will finish the Massachusetts General Hospital (MGH) Acupuncture Sensation Scale (MASS) to evaluate deqi sensations.

NCT02859233
Postdural puncture headache (PDPH) is defined, according to the International Headache Society, as any headache develops within 5 days after a lumbar puncture. It worsens within 15 minutes after sitting or standing and improves within 15 minutes after lying. For preventing PDPH, there are some uncomfortable practices for patients (fluid supplementation and bed rest) and expensive for hospital (time spend for information and management of fluid intake). Patients are usually advised by nurses. If "bed rest" is not effective in prevention of PDPH, "fluid supplementation" is not an advice based on any evidence but only on routine. By this trial, the investigators want to evaluate the scientific value of this advice, in the standard patient care. The primary objective of this study is to compare oral hyperhydration (2 liters during 2 hours after lumbar puncture - the most common routine according to an internal pilot survey) versus no advice about the fluid intake to prevent the PDPH. The second objective is to observe the day of apparition of PDPH, between day 0 and day 5.

NCT03790124
Neuraxial techniques are widely used in obstetric practice to provide analgesia and anesthesia. A common complication associated with neuraxial anesthesia is post-dural puncture headache (PDPH), resulting from unintentional or unintended puncture of the dura mater during insertion of an epidural needle. Incidence of PDPH after spinal anesthesia is very low due to the widespread use of non-cutting small diameter spinal needles. Incidence of "wet tap" during epidural injection has been reported to be 1.5%, with 52-85% of these patients developing PDPH. When an obstetric patient develops PDPH, institution of an effective treatment is necessary. Although PDPH tends to resolve spontaneously over a couple of weeks, it carries the risk of potential complications. PDPH interfere with the ability of the mother to take care of her baby, increases the risk of chronic headache and limits early ambulation, thereby increasing the risk of venous thrombosis and pulmonary embolism. As important as treating PDPH when it occurs is to prevent it when the dura is accidentally punctured during labor epidural placement. Multiple therapeutic strategies have been reported in the medical literature to prevent this outcome. Preventive measures range from conservative strategies to invasive procedures. Bedrest and hydration have been traditionally recommended to try to prevent PDPH when a wet tap occurs; however, no conclusive evidence supports their use. The use of oral and intravenous caffeine is insufficiently supported by clinical evidence. Epidural morphine and intravenous cosyntropin have been successfully used to prevent PDPH. Epidural injection of normal saline reduces the gradient for CSF leak. The use of saline has shown variable results in different studies. Although the results of some studies show insufficient evidence about its effectiveness, administration of epidural saline is a technique relatively devoid of significant adverse effects. The institutional protocol recommends the combination of a multimodal approach to prevention of PDPH after accidental dural puncture, based on strategies reported in the medical literature. The protocol consists of the immediate administration of 60 cc of epidural normal saline, followed by two preventive measures administered after delivery. After delivery, 1 mg of intravenous cosyntropin and 3 mg of epidural morphine before catheter removal are administered. This study tests the hypothesis that the multimodal prophylactic protocol described above decreases the incidence of PDPH and the need to perform epidural blood patch, compared to other strategies or no prophylactic management.
