Filter by:This will be a randomized, multi-site double-blind placebo-controlled trial of melatonin (2 different dosing arms) vs. placebo for migraine prevention in adolescents. We intend to enroll approximately 210 participants over 15 months at two sites: UCLA and UCSF. The duration of participation for each participant will be 4 months.
Sporadic and chronic dietary consumption of caffeine has substantial biological effects on the nervous system. The effects on migraine are at large not known. In this study we want to assess the effects of caffeine withdrawal on migraine.
This study investigates whether non-invasive brain stimulation, given for 20 minutes/once per day for ten days (M-F) can reduce migraine pain. Thirty patients will receive this treatment, while thirty will receive a "sham" procedure. Up to thirty healthy volunteers will be asked to undergo baseline assessments only (imaging, but no brain stimulation). Healthy volunteer data may be used from a prior study (NINDS-K23062946 project [IRBMED #HUM00027383; Dr. Alexandre DaSilva, Principal Investigator]).
The goal of this study is to determine whether timolol eye drops are effective in alleviating acute migraine headaches. Subjects will be randomized to receive either timolol eye drops or placebo (tears) to use as a migraine abortive medication.
The primary purpose of this study is to evaluate the safety and tolerability of multiple oral doses of AMG 333 for 14 days in healthy subjects and migraine subjects. As part of the secondary objectives, the study will characterize the pharmacokinetic (PK) profile of AMG 333 after multiple oral doses in healthy subjects and migraine subjects, as well as characterize the effect of multiple doses of AMG 333 on increases in blood pressure (BP) induced by the cold pressor test (CPT) in healthy subjects.
PF-05180999 is a phosphodiesterase-2 inhibitor that is hypothesized to be able to reduce vascular permeability. The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and effects on histamine-induced wheal of single doses of PF-05180999 in healthy adult subjects. Histamine-induced wheals are biomarkers of vascular permeability.
The purpose of this study is to look at two different diets (a low carbohydrate diet and a low fat diet) for migraine prevention in overweight or obese persons with migraine. The overall aim is to test the theory that diet will improve migraine frequency and that such improvements will be associated with favorable changes in body weight, inflammation, and heart health.
This trial assesses the impact of a supervised aerobic exercise program by a kinesiologist in patients with migraine. Patients can be assigned to one of two groups 1)The exercise group or 2)non-exercise group. This is a important area to study because there is currently limited information regarding exercise and its impact on migraine frequency and severity. In many cases, migraine patients are disabled by their headaches and sometimes will not have a significant response to medications. As a result, it is important to study other non-pharmacological interventions. In this study, the investigators hope to show the benefits of exercise by a reduction in number of headache days per month as well as by improvement in quality of life, disability,depression,anxiety,and aerobic fitness.This study will not interfere with the usual treatment patients receive at our headache clinic and patients can remain on medications deemed necessary.
The objective of this proof-of-concept study is to generate initial safety and effectiveness data for the neuro-modulation stimulation (NMS) E-Box in patients with chronic migraine in an acute setting. The results of this study will determine if further development of this device in a larger study is warranted.
Migraine is a very common, chronic/intermittent and disabling neurovascular headache disorder that has long believed to have no severe consequences. Recent evidence, however, strongly suggest that migraine is associated with increased risk of ischemic stroke and there is initial evidence that migraine is associated with structural brain changes independent of the occurrence of stroke. As migraine has strong links with the vascular system, it is plausible that vascular functions interact on the association between migraine and structural brain changes as well as cognition. Our primary objectives are to investigate: (i) the relationship of migraine and migraine subtypes on magnetic resonance imaging (MRI) changes in a cohort of patients with active migraine; (ii) the relationship of migraine on cognitive performance among patients with active migraine; and (iii) the relationship of migraine and migraine specifics with vascular functions and morbidity. As secondary objective, we investigate whether the association of migraine on structural brain changes or cognitive performance is modified by vascular functions. This will be an observational study conducted in the Headache Center in Bordeaux. 300 patients have to be included (150 patients with migraine with aura and 150 patients with migraine without aura). Inclusion criteria are: all patients with a clearly defined migraine (as per IHS[International Headache Classification] criteria) who are aged 30 and older, are able to fluently speak French, and who are willing to participate. Exclusion criteria are: pregnant woman and patient who have a major psychiatric disease or major anxiety disorder or had a pacemaker (which would not allow to perform a MRI imaging). The cognitive status in the patient cohort will be ascertained by the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). In addition to the RBANS, we will use the HIT-6 (Headache Impact Test) and MIDAS (MIgraine Disability ASessment) and the depression scale CES-D (Center for Epidemiologic Studies Depression Scale). Vascular risk status will be assessed by measurement of blood pressure and reports of vascular risk factors. The endothelial function will be measured with a noninvasive Peripheral Arterial Tone (PAT) signal technology using the EndoPAT device (Itamar Medical Inc, Framingham, MA). For crude comparisons, chi-square tests will be used for categorical variables and t-test for continuous variables. Multivariable-multinominal modeling techniques will be utilized for the comparisons adjusting for potential confounding variables. All statistical tests will be two-tailed and a P <0.05 will be considered statistically significant.
