Filter by:Migraine is a highly disabling disorder that affects hundreds of millions of people around the world. Yet, a little number of prophylactic treatments are available still now. The limited number of available drugs leads to a wide use of nutraceutical compounds in migraine therapy. To improve the efficacy, some of these nutraceuticals were combined. So far, we do not know if these combinations are really more effective than the single compounds alone, or an anti-synergic effect could be present because of a reciprocal antagonism of effects. For this reason, we decided to test the efficacy of a fixed combination of magnesium, partenium, andrographis, co-enzyme Q10 and riboflavin (PACR) as prophylactic treatment for migraine in a randomized controlled double blind study.
According to recent studies, we want to find evidences that infant colics could be a episodic symptom associated to migraine as cyclic vomiting syndrome or abdominal migraine are. The main purpose is to compare the presence of colics in infants between 60 days and 180 days of life and the presence of migraine in their parents to determine if colicky children's parents are more migrainous than other parents.
An increase in intracranial pressure (ICP) during migraine attacks is possible and could contribute to pain initiation and maintenance. From now on, it was not possible to measure ICP in a non-invasive way. The development of a new tool allows non-invasive self-measures of ICP variations. Thus, it is possible for the first time to look for such ICP variations during migraine attacks and to conclude if this mechanism is implied in the pathophysiology of migraine.
The main goal of this study is to determine whether it is possible - in the setup of routine clinical care - to identify in individual patients who are clear responders to drug X, common denominators that are absent in individual patients who are non-responders to the same drug, and vice versa. All currently available knowledge about migraine pathophysiology will be utilized, using as much time as is needed to ask as many questions as are necessary, in an attempt to profile clear responders and clear non-responders.
Migraine is the most common headache disorder, prevalent in 18% of females and 6% of males. Emergency room visits, physician consults, hospitalizations, medications, and indirect costs such as lost work days and decreased productivity place the global economic burden of migraines at over 20 billion dollars. It is prevalent in 28 million people in the US alone. Symptoms include unilateral, throbbing, debilitating headache pain accompanied by nausea, vomiting, photophobia, and phonophobia. Upwards of 75% of migraine patients have reduced functionability, have lost time at work, and 1/3 of patients require bed rest to manage the symptoms. The health-related impact on quality of life was comparable with that experienced by patients with congestive heart failure, hypertension, or diabetes. While the burden of migraines on our society is clear, the pathophysiology of migraines remains largely unknown. The trigeminovascular system, including the external and internal carotid arteries and their associated sensory fibers which subserve the head have long been implicated in the pain and cutaneous allodynia experienced by migraine patients. Wolff in 1953, was the first to posit that migraine headache pain is the caused by dilation or circumferential expansion of the extracranial carotid artery. He demonstrated that migraineurs had twice the pulse amplitude in their external carotid arteries compared to control subjects and these changes were directly correlated to migraine symptoms. In a 2008 study, randomized migraineurs received nitroglycerin via peripheral IV or placebo for 20 minutes prior to obtaining magnetic resonance angiography (MRA). Nitroglycerin, a potent dilator of blood vessels, reliably induced migraine-like pain in up to 80% of patients, and transient dilation of vessels of up to nearly 40%, mostly in the extracranial vessels. Sumatriptan's efficacy in migraine relief provides further evidence for this theory, as it is a selective extracranial vessel constrictor which does not cross the blood brain barrier. The goal of this current work is to utilize the direct, real-time angiography, which provides a high resolution map of vasculature, and demonstrate changes in vessel flow in patients who have migraine headache attacks. This information may guide therapeutic interventions in the future in order to better treat these migraine patients.
This study evaluates the treatment of migraine pain using low energy laser light to quench migraine signals issuing from the sphenopalatine ganglion (SPG).
The underlying mechanisms of association between the right-to-left shunts (RLS) and migraine may concern with platelet aggregation and paradoxical embolization. The aim of the study is to evaluate the prophylactic effectiveness of clopidogrel for migraineurs with RLS.
Background: Headaches is one of the most common complaints of children in the ED and the treatment of pediatric migraine is largely based on extrapolation data from adult studies, limited pediatric trials, clinical experience and expert consensus. Despite the fact that dexamethasone has already been proven effective to reduce recurrence and is currently used in treating adults with migraine, no studies have looked at its use in the treatment of childhood migraine where relapse rate of about 50% are described in the 48h following successful treatment in the ED. Objective: To examine the effectiveness of parenteral dexamethasone at preventing migraine recurrence in children and to study the risk factors for migraine relapse after discharge from the ED. Methods: This a randomised, double-blind, placebo-controlled clinical trial among all children 8 to 17 years of age with a presumptive diagnosis of acute migraine and treated with a standardized protocol in the ED of the CHU Ste-Justine, a tertiary care pediatric hospital. After the parenteral administration of prochlorperazine or metoclopramide and diphenhydramine, the patients were randomised to receive either dexamethasone or a placebo. They were excluded from the intervention if they had a known allergy or absolute contraindications to receiving parenteral corticosteroids, if they were already on a corticosteroid regimen or if they did not respond to the initial abortive migraine therapy. All included patients were discharged on a 48-hour course of naproxen and with a headache diary to fill out and return. The primary outcome was the incidence of relapse in the 24-48h following discharge from ED. The secondary outcomes evaluated were the mean level of pain, the use of rescue medication after ED discharge, the return rate to the ED or the visit to a health care professional within 7 days including hospitalisation. The associated symptoms, the adverse events after parenteral corticosteroids and the risk factors for migraine relapse were also evaluated. A telephone follow-up was made to ensure the headache diary was completed and returned.
This study is a pilot, double-blind, placebo-controlled, randomized trial aiming to compare the effects of transcranial direct current stimulation in Chronic Migraine.
The foramen ovale, a kind of physiologic channel in the interatrial septum in the heart at embryonic stage, is closed normally at 5-7 months after birth. When it is not closed, it is referred to as the patent foramen ovale (PFO), which is found in approximately 1/4 of general population. It was shown in the studies in recent years that the risks of cryptogenic stroke, migraine, peripheral arterial embolism and decompression sickness in the patients with PFO were several times higher than those in healthy people. Therefore, PFO, previously considered a condition without the necessity of treatment, causes the attention of many experts and scholars around the world. Migraine with or without aura is defined as one of the most disabling chronic diseases, since according to WHO, the disability adjusted life year caused by migraine was second only to that by non-fatal stroke in 2005. In recent years, an increasing number of researches suggested that migraine is closely related to the right-to-left shunt (RLS) in the heart. And PFO is clinically considered as the most common cause of RLS. The closure treatment for PFO-induced migraine has been gradually applied in several hospitals in China. The relationship of PFO with migraine, however, was not evaluated systematically based on specific standards, unfortunately leading to non-inclusion of many high-risk patients with PFO in the evaluation. The following aspects are to be fully recognized: the selecting and screening procedures for the high-risk population with PFO-induced migraine; the indications and standards of closure treatment for PFO in the patients with PFO-induced migraine; and the possibility that the made-in-China occluders substitute for those imported in the prevention from migraine. Furthermore, there is still a lack of prospective, multi-center, randomized and controlled studies in this subject, and standard or normal screening and treatment procedures have not yet been established in China. From this point, the investigators developed the Chinese people-specific procedures and standards of diagnosis of PFO-induced migraine in this study, based on current standards and methods of diagnosis, treatment and prevention of PFO-induced migraine in foreign countries. And the investigators prospectively adopted continuous inclusion of the high-risk patients with PFO-induced migraine, who were randomly divided into the closure treatment (transcatheter closure of PFO) group and the medication (drugs administered alone) group at the ratio of 1:1., in order to evaluate if the interventional treatment is better than the medication alone in these patients, to assess the efficacy and safety of the made-in-China occluders in the interventional treatment and prevention of PFO-induced migraine, and to identify the incidence of PFO in the patients with migraine in China and develop the Chinese people-specific screening protocols of PFO-induced migraine.
