The purpose of this study is to show the efficacy of promethazine in management of patients with moderate to severe migraine
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.
This study will highlight and validate chiropractic spinal manipulative therapy (CSMT) for migraine. If the method proves to be effective, it will provide a new non-pharmacological treatment option for migraine. This is especially important since some migraineurs do not tolerate acute and/or prophylactic medicine, due to side effects or contraindications due to comorbidity of other diseases while others do not have effect. Thus, alternative treatment options are warranted. The applied methodology of the study will aim towards the highest possible research standards. This international study is a collaboration between Akershus University Hospital, University of Oslo (UiO), Norway and Macquarie University, Australia. The multidisciplinary professional backgrounds are physiotherapy, chiropractic and medicine. By increasing the methodological quality of the investigators research to a very high level, the investigators see the method to work as a guide to increase the quality of chiropractic research in the future, as previous randomized clinical trials (RCTs) of migraine used methodology showing room for improvement.
The purpose of this study is to determine the effects of triptans and doxycycline on neuroinflammatory markers in acute migraine.
Migraine headaches are a common problem for children. When treatment at home fails, children may benefit from intravenous treatment administered in a hospital setting like the Emergency Department. Most treatments used however have only been tested in adults and the best treatment strategy for children is not always clear. The combination of more than one medication is frequently prescribed in Canadian Emergency Departments. The purpose of this study is to investigate whether the combination of ketorolac (an anti-inflammatory pain medication) and metoclopramide (an anti-nauseant that may also relieve migraine headaches) is better than metoclopramide by itself.
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.
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.
This is an open label pilot study to determine whether milnacipran can reduce headache frequency in episodic and chronic migraine sufferers.
The purpose of the study is to compare the rate of comorbidities associated with migraine aura (MA) between persons who have a large circulatory right-to-left shunt (RLS) and those who do not have RLS. Approximately 50% of individuals who have MA also have RLS due to patent foramen ovale (PFO). A PFO is an anatomical opening or flap between the upper chambers of the heart or atria that permits blood to pass from the right of the heart to the left side of the heart, without first going to the lungs to be filtered and oxygenated. Many health conditions and clinical syndromes including stroke, sleep apnea, and migraine have been linked to PFO. Although the mechanism is undetermined, it is hypothesized that microscopic blood clots and chemicals such as serotonin can pass through the PFO, travel to the brain, and cause headache and aura. Persons who have MA are at increased risk for stroke and transient ischemic attacks relative to people who do not have migraine. Migraine is also associated with the presence of white matter lesions in the brain and mild deficits in cognitive function associated with the posterior brain (vision, memory, processing speed). The risk of stroke in migraine is highest for women under the age of 45 who have aura and a high number of migraine headache days per month. No convincing evidence has been produced to explain the mechanism for the increased risk of ischemic stroke in migraine; however, increased platelet activation and aggregation is a plausible theory. We hypothesize that migraineurs with aura and large RLS (presumably due to a PFO) will be more likely to have sleep apnea, increased platelet activation, cognitive deficits, alterations in cerebral vasomotor function, and white matter lesions than migraineurs with aura who do not have PFO. The results of this exploratory study will generate hypotheses as to why subgroups of migraineurs have an increased risk of stroke and the impact of large PFO on comorbid conditions associated with migraine aura. Early identification of migraine subgroups with a constellation of clinical syndromes that increase risk of neurovascular diseases will allow initiation of preventive strategies that may ultimately reduce burden and improve the productive quality of life for these individuals.
