Migraine and Endothelial Dysfunction

Migraine With Aura

Recently, there is evidence that endothelial activation and dysfunction are associated with migraine, especially in female migraineurs with aura. Our objectives were to determine whether novel endothelial function markers are altered in female migraineurs with aura compared to age-matched controls.

Impact of a Nurse for Migraine Management: the IMPACT Project

Migraine Without AuraMigraine With Aura1 more

Headache disorders are prevalent, disabling, under recognized, under diagnosed and under treated. Migraine has a prevalence of 10% in men and 25% in women in Canada. The treatment of migraine is based on patient education (lifestyle habit modification, trigger avoidance), and pharmacological acute treatment and prophylaxis. A multidisciplinary approach allows a repartition of tasks between different health professionals. In a 2010 meeting, the Canadian Headache Society members supported the concept of Headache Centers, and a headache nurse was judged as an essential component of such centers. Gaul has reviewed the structured multidisciplinary approach that could be used in a headache centre and the existing studies using such structures. Five studies did include a headache nurse. No study did observe the impact of a nurse only. Resources in medical care are limited. One study did use a program of 96 hours, which does not seem realistic on the long-term and for a large pool of patients in a public hospital. Patients are not always able to pay for paramedical help such as physiotherapy and psychotherapy. Even if they do, finding a specialized therapist for chronic headache is difficult. Defining the role of a nurse and demonstrating the impact on patient care is therefore a first step in the concept of a headache center. Possible roles of a headache nurse according to Gaul are patient education, follow-up of the treatment plan, addressing patient queries, and monitoring of patient progress. The headache nurse may also participate in research projects. In a hospital Headache Clinic, the nurse may be involved in intra-venous treatments and blood sampling for research. In summary, evidence to demonstrate the impact of a nurse in a headache clinic is lacking. We propose to study this aspect prospectively. A study with positive findings would encourage health ministers to fund and support headache nurses for headache centers across Canada for headache management. Chronic headache and therefore chronic migraine would be a focus of such centers, since most patients seen in specialized centers are chronic. HYPOTHESIS: The addition of a headache nurse to the headache team will help the CHUM Migraine Clinic to improve treatment outcome, and reduce the burden of headache. This multidisciplinary approach will also allow a higher efficiency of the team.

IndoProCaf Effervescent Tablets Effectiveness in Acute Treatment of Migraine and/or Episodic Tension-type...

Headache DisordersPrimary3 more

Headaches are a common medical problem that physicians frequently encounter in their practice. One of key findings of The Atlas of Headache Disorders prepared by World Health Organization (WHO) is: headache disorders, including migraine and tension-type headache (TTH), are among the most prevalent disorders of mankind. The fixed combination of indomethacin, prochlorperazine and caffeine (IndoProCaf) showed efficacy and safety in acute treatment of migraine and episodic tension-type headache attacks. IndoProCaf (Difmetre®) is widely used in common daily practice only in Italy from early 1970s, is available at the Commonwealth of Independent States (CIS) pharmaceutical market now. There are limited data regarding IndoProCaf usage from post-marketing settings. This will be a first post-marketing observational study which aimed to evaluate the effectiveness and patients' satisfaction of primary headaches acute treatment in routine clinical settings in Ukraine and Kazakhstan.

Endothelin-1 as a Potential Trigger of Migraine Aura

Migraine With Aura

One third of migraine patients experience aura, i.e. dramatic, transient neurological symptoms, most often in the form of visual disturbances, that usually appear before the onset of migraine headache. The likely underlying mechanism of aura is known as cortical spreading depression, a wave of changes in electrical activity that slowly spreads in the outermost layer of the brain. It is currently not known what causes the aura to initiate in patients or what the relationship is between aura and migraine headache, e.g. if treatment targeted at aura mechanisms will prevent subsequent headache. Due to the short-lasting and unpredictable nature of aura, the only possible approach for systematic investigations is to experimentally trigger aura, but currently no method for aura-triggering is available. The overall goal of the proposed project is to reveal the earliest mechanisms of the migraine attack by investigating the initiating factors of aura in the migraine brain. Current animal evidence indicates that infusion of endothelin-1 (ET-1), a naturally occurring signaling molecule released from blood vessels, is safe and very likely to trigger migraine aura in patients. In this project the investigators aim to study the effects of ET-1 on the human brain, to investigate aura-inducing effects of ET-1 in patients and to develop a safe and reliable method for the experimental induction of migraine aura using ET-1.

Pharmacologically Triggered Migraine Without Aura and Neuroimaging

Migraine With Aura

Migraine is a highly disabling disorder affecting 14% of the general population Worldwide and ranked as the 6th most debilitating disease worldwide by the WHO. One of the most fundamental questions of migraine, which remains to be elucidated, is the mechanism behind the generation of migraine attacks. The investigators will use calcitonin gene-related peptide (CGRP) and sildenafil as pharmacological triggers of migraine, combined with advanced neuroimaging techniques, to investigate the attack initiating pathophysiology. Both substances have previously been administered to healthy participants and migraine without aura patients, inducing headache and migraine-like-attacks. The investigators hope to contribute with novelty to the current understanding of the migraine pathophysiology and development of more efficient treatment of migraine.

Functional MRI and MRA in Migraine With Aura

Migraine With Aura

Patients who report that exposure to bright light or strenuous physical activity will induce migraine aura will be provoked using one or both of these methods. Followingly the patients will be examined by functional MRI. Íf the patients develop migraine headache, MR angiography will be performed as well. The primary study hypothesis is that the functional MRI signal will show features similar to those of the electrophysiological phenomenon of cortical spreading depression.
