Filter by:This study will be conducted as a retrospective study of exposed and unexposed cohort of the French population included all beneficiaries aged 65 and older. Exposed patients will be matched to non exposed controls according age, gender and area of residence (ratio 1/4). Two exposed arms and two non exposed control arms will be planned. Triptan arm will be user of triptan defined as at least one recorded dispensing of any drug during the follow up, with no recorded of any of these drugs during the previous 6 months ("new or incident users"). Ergot arm will be user of ergot derivative defined as at least one recorded dispensing of any drug during the follow up, with no recorded of any of these drugs during the previous 6 months ("new or incident users"). This study involved data from the French National Health Insurance Information System (Système National d‟Information Inter-Régimes de l‟Assurance Maladie ; SNIIRAM) linked with the French hospital discharge database (Programme de Médicalisation des Systèmes d‟Informations, PMSI). - The SNIIRAM is a vast national medico-administrative database representing the most part of the French population, allowing to identify and to describe precisely all medication dispensations (name of drug, date of dispensing and quantity) including triptans and other reimbursed medications. - The PMSI provides medical information about all patients admitted to hospital in France, including discharge diagnoses encoded according ICD-10, medical procedures and French diagnosis-related groups The research proposed is expected to provide an update and nationally-consolidated estimation of the cardiovascular risk is associated to triptans use in elderly population.
This study evaluates the use of brain activity monitoring for prediction of migraine attacks in an expected time scale of 12-48 hours prior to the migraine attack.
Fibromyalgia and migraine are diseases with high prevalence in women between the age group of 30-60 years, which seem to share the same pathophysiological mechanism; both originate from neuroendocrine disorders of the hypothalamic-pituitary axis in the central nervous system, and are therefore closely related. In addition to the strong relationship with migraine, fibromyalgia can also be associated with sleep disorders, chronic fatigue and psychological disorders. The combination of these factors decreases the quality of life and contributes to increased sedentary this population. It is known that physical exercise promotes positive changes in pain pathophysiological pathway to increase the release of endorphins neuroendógenas, improving the symptoms of fibromyalgia. The objective of this study is to analyze whether the application of an aerobic exercise program may result in the reduction of the frequency, duration and intensity of migraine attacks in women with fibromyalgia. For this, a clinical trial will be conducted randomized double-blind clinical trial comparing two groups of women diagnosed with fibromyalgia and migraine. Initially, all answer questionnaires assessing quality of life, impact of headache, level of depression and anxiety, sleep quality, physical activity level, and; will be held ergospirometry for research in exercise tolerance. The experimental group will implement the protocol consists of heating, aerobic exercise according to the heart rate established for training by spirometry and slowdown; and the control group will hold the heat on low speed and heart rate will next baseline. Both groups will be followed for 12 weeks, with a frequency of three weekly meetings lasting 30 minutes and re-evaluated every 4 weeks. At the end of the protocol, the groups will have their results were compared and statistically analyzed.
Optical coherence tomography (OCT) is a non-invasive retinal imaging technology that can provide high-resolution cross-sectional images of the peripapillary retinal nerve fiber layer (RNFL) and measure its thickness. A reduction of the RNFL thickness has been detected in several neurodegenerative diseases, such as multiple sclerosis, CADASIL and Alzheimer's disease. Different studies have reported RNFL changes also in migraine, is a common hereditary chronic neurovascular disorder, characterized by dysfunction of the autonomic nervous system. The pathophysiology of migraine has not been fully clarified, but there is increasing evidence that episodes of migraine with aura are initiated by a focal reduction in cerebral blood flow, which occurs most commonly in the posterior region of one hemisphere. Although vasoconstriction of cerebral and retinal blood vessels is a transient phenomenon, the chronic nature of the migraine might cause permanent structural abnormalities of the brain and also of the retina, which may correlate with RNFL thinning. Previous studies on this subject, however, reported contradicting results. Some investigations reported reductions of the RNFL thickness while others did not. In the present study, in order to determine whether RNFL thickness is reduced in migraine patients, the investigators performed a meta-analysis and systematically evaluated RNFL thickness measurements with OCT in a series of migraine patients and in the healthy control groups.
Migraine has been described as one of the most common neurological diseases, with high social and economic impact. Despite the high prevalence, the pathophysiology of migraine is still unknown, several studies have been developed in order to advance the understanding of the pathophysiological mechanisms of the disease which are not yet entirely elucidated. The aim of this study is to observe the effects of transcranial direct current stimulation (tDCS), applied in the visual cortex, on neurophysiological and clinical measures (frequency, intensity, duration of attacks and severity of pain) in migraine patients.
This study is an interventional trial to evaluate the effectiveness of a cognitive and physical program (Intervention), in reducing the frequency of head and neck pain in the population of an extensive territory of Italy.
Migraine in children and adolescents can be associated with low serum levels of coenzyme q10, the key-enzyme of mitochondrial energy production.During migraine attacks inflammation is an important issue. Based on a double-blind placebo-controlled trial with coenzyme q10 in adults it is hypothesized that daily supplementation of coenzyme q10 as well as different antioxidative phytochemicals (from berries) and specific minerals and vitamins are able to reduce the "days with migraine" as primary parameter (open clinical trial).
We hypothesised that intravenous infusion of PGI2 induced headache or migraine and cranial vasodilatation in migraineurs.
The release of the neuropeptide calcitonin gene-related peptide (CGRP) is thought to play a causative role in migraine. Nociceptin immunoreactivity and ORL-1 mRNA have been detected in human trigeminal ganglia where it was co-localized with CGRP. It may play a role in migraine pathogenesis. We are collecting the blood samples of migraineurs for analysis of these neuropeptides.
This study will examine how depression, anxiety, and migraine run in families. It will help in defining the risk factors for physical, mental, and health problems-as well as define ways that those problems may be prevented and treated. A broad range of ages among family members will be included to evaluate the patterns of how these disorders are expressed throughout people's lives. Children of all ages will be included, and those ages 8 to 17 will be interviewed directly. Assessments will be collected through criteria of the Diagnostic and Statistical Manual of Mental Disorders IV as well as the spectrum, or range, of mood disorders and co-existing conditions. A member of the study team will visit the participants at home or will do an interview by telephone. Participation will take approximately 3 to 4 hours. Children will complete questionnaires given by the research team as well as questionnaires that they will do by themselves. The questions will pertain to the children's health, including physical and mental health and medical history, social relationships, problems, skills, and ways of dealing with important or stressful issues in their lives. These questionnaires will take up to 1 hour to complete. Health history gathered from adult participants will pertain to height, weight, exercise, and general function. Women will be asked about the use of oral contraceptives, estrogen, and progesterone. In addition, there will be questionnaires on personality and temperamental traits, that is, behavior and impulsiveness. Questions will also involve social intuition, family and other environmental factors, general functioning, and basic demographics such as ethnicity, race, socioeconomic status, marital status, education level, and employment history. Families enrolled in this phase of the research will be invited to participate in the next phase. There would be follow-up to evaluate the development of mood disorders, subtypes, and syndromes across the lifespan.
