Filter by:In this study the investigators will research the hypothesis that the gas carbon monoxide induces headache and increases the blood flow velocity in the middle cerebral artery.
The purpose of this study is to evaluate the safety and the efficacy of Tianshu capsule treating Migraine Headache.
A small number of chiropractors, who align only the atlas C-1, or "top" vertebra in the spine, practice the National Upper Cervical Chiropractic Association (NUCCA) atlas correction procedure. This procedure uses a precise, non-invasive, gentle touch technique to correct misalignment of the atlas. Although NUCCA practitioners have long used this procedure in the treatment of headache, it has not been formally studied using clinical trials. There is some data indicating that NUCCA correction can increase intracranial compliance. This intracranial compliance can be measured by a magnetic resonance imaging (MRI) study before and then after a NUCCA procedure. In this study, the investigators hope to show that the correction of an atlas misalignment will increase intracranial compliance in subjects with migraine.
The placebo effect is a phenomenon that has experienced major advances of its understanding in the last decade. However, mechanisms of placebo analgesia in chronic pain patients have yet to be compared to healthy subjects. The investigators study aims to investigate the magnitude of placebo response and related opioid release in patients that suffer from episodic migraines as compared to healthy controls. In particular, the investigators are looking to map brain activity during placebo analgesia using modern brain imaging techniques such as functional Magnetic Resonance Imaging (fMRI) and Positron Emission Tomography (PET). The investigators hypothesis is that placebo response and the availability of opioid receptors is reduced in chronic migraine patients.
The primary purpose of this study is to determine whether AMG 333 is safe and well tolerated in healthy subjects and subjects with migraines. As part of the secondary objectives, this study will characterize the pharmacokinetic (PK) profile of AMG 333, as well as characterize the effect of AMG 333 on the cold pressor test (CPT)-induced increase in blood pressure after single oral doses in healthy subjects and subjects with migraines
A study to evaluate the effect of erenumab compared to placebo on the change from baseline in monthly migraine days in participants with episodic migraine.
The primary objective of this study is to evaluate the efficacy of sphenopalatine nerve block utilizing the Tx360 (device) to deliver an anesthetic agent (bupivacaine) and to assess the duration of the analgesia.
The primary objective is to determine whether inflammatory markers, such as C-Reactive Protein (CRP), Calcitonin Gene-Related Peptide (CGRP), Vasoactive Intestinal Polypeptide (VIP), or Substance P (SP) are reduced in patients having a migraine headache when treated with Imitrex or Treximet. The secondary objective is to determine the effects of Imitrex and Treximet on C-Reactive Protein (CRP) in patients with active migraine headaches.
This study will be looking at the clinical efficacy of using a intranasal evaporative cooling device in providing relief of the symptoms of migraine and cluster headache. It will involve using a nasal catheter to spray a liquid coolant into the nasal cavity where it evaporates and removes heat from the tissue, thereby cooling the tissue and the blood vessels which supply blood to the brain. This cooling effect will cause the blood vessels to constrict and it is thought that this may provide symptomatic relief in both these forms of headache. 10 migraine patients and 5 cluster headache patients will be enrolled in the study and will receive 10 treatments each, for a maximum of 20 minutes at a time. They will be monitored during the treatment and for two hours afterwards to assess headache severity and side effects. There will be a further follow up 2 months after the last treatment to assess for longer term side effects from the treatment.
In this study the investigators will investigate the following hypothesis - that hypoxia induce migraine headache and migraine aura - the aura phase is associated with a spreading reduction in cerebral blood flow - the migraine headache is associated with dilatation of intra- and extracerebral arteries - the migraine headache is associated with changes in brain metabolism - the pre-ictal stage of a migraine attack with aura is associated with specific patterns in neural activity.
