6 Clinical Trials for Various Conditions
The purpose of this study is to determine if prazosin is more effective than placebo in decreasing frequency, severity, disability, and other negative effects of headaches related to mild traumatic brain injury in Service Members and Veterans.
This study evaluates the use of osteopathic manipulation (manual medicine) for migraine headache following traumatic head injury. Headache is an important and very common somatic complaint among people with traumatic brain injury and an important cause of disability in the United States. Over 15-percent of soldiers deployed to Iraq sustained concussion. A majority of these patients suffer from headaches. Many of these are classified as migraine headache that do not respond to medications. Osteopathic manipulation is practiced by physicians in the United States and has been shown to be beneficial in some migraine patients. However, its use in the management of persistent post-traumatic headaches has not been explored. The investigators will use a randomized cross-over design to evaluate post-traumatic migraine patients' response to osteopathic manipulation.
Eligible participants will complete the COMPASS 31 (year), modified COMPASS 31(one month) and the NSI (one month) questionnaires at baseline and complete the modified COMPASS 31 and the NSI after usual care of treatment. The investigators will 1. Compare results for the COMPASS 31(year) to the modified COMPASS 31(month) at baseline. 2. Compare modified COMPASS 31(month) to the NSI at baseline and post intervention.
The goal of this observational study is to learn how the brain's information processing changes during and following administration of serotonergic psychedelics (psilocybin, N,N-Dimethyltryptamine/DMT, Lystergic Acid Diethylamide/LSD, etc.) for people with and without mental illness receiving serotonergic psychedelics through any clinical trial at Yale University. The main questions it aims to answer are: 1. Do serotonergic psychedelics cause the brain to rely on new information more than previously learned information while under the influence? What about 1 day, 5-14 days, and 4-6 weeks after use? 2. Do serotonergic psychedelics cause long-lasting side-effects in how people perceive (see, hear, feel, etc.) the world and how easily people change their beliefs? 3. How does the brain's electrical activity change after using serotonergic psychedelics? How does the balance between excitation and inhibition change while under their effect? 4. Can changes in how the brain uses information predict who will benefit from a psychedelic and who will have side effects from psychedelics? Researchers will compare with people given placebos to see what changes in brain processing are unique to serotonergic psychedelics. Participants will have the opportunity to do some combination of the following: 1. Online computer assessments consisting of games and questionnaires that probe how participants think. 2. Magnetoencephalography (MEG) or electroencephalography (EEG) with eyes closed and with repeated clicks, images, or sensations delivered. 3. A magnetic resonance imaging (MRI) scan. 4. Semi-structured qualitative interviews about their experience after taking a serotonergic psychedelic recorded via Zoom.
This study will be focused on assessing the molecular, physiological, and emotional correlates of an intensive meditation experience in the context of a retreat setting in a large 2000 plus-person cohort comprised of healthy and clinical populations.
Study Purpose: This study will explore the feasibility of administering Holographic Memory Resolution® (HMR) to adults who are experiencing chronic pain for 6 months or more.
