People with migraine typically show impaired responsivity to visual, auditory and pain stimuli (Burstein et al, 2015). The electrophysiological study of the nociceptive blink reflex (nBR) is widely adopted for the instrumental evaluation of trigeminal afferent function. Migraine sufferers characteristically show deficits in the habituation to repeated stimulations of various sensory modalities, in the interictal phase of the disease (Bohotin et al, 2002; Di Clemente et al, 2005). It has been described how the habituation / sensitization pattern presents a characteristic pattern over the course of the migraine cycle. Past evidence suggests that the habituation deficit may turn towards a normalization of the pattern near the acute migraine attack (Coppola et al, 2013; Katsarava et al, 2003). However, the study of the spontaneous attack shows various limits and difficulties, mainly due to the impossibility of predicting the onset of the next attack and of standardizing the experimental conditions. The use of human models of migraine allows us to overcome these obstacles. Di Clemente et al. (2009) evaluated the electrophysiological changes in nBR after administration of nitroglycerin (NTG) in healthy subjects. The authors described a modification of trigeminal circuits and cortical responses (visual evoked potentials) after NTG. However, NTG administration does not induce migraine attack in healthy subjects, therefore this model cannot be directly translated to migraine pathology (Ashina et al. 2017). Our group has previously used the human model of migraine based on the administration of NTG to study central and spinal level sensitization through the nociceptive avoidance reflex in the lower limb (RIII) (De Icco et al. 2020). The results of the previous study deepened our understanding of the central mechanisms of sensitization. The investigation of the nBR allows to study the modulation of the caudal trigeminal complex (TCC). In the present study we therefore intend to evaluate, under well-controlled experimental conditions, the modulation of the trigeminal caudal complex during an experimentally induced migraine attack. The study will allow us to confirm or not the normalization of habituation described in the acute phase through the adoption of a solid cross-over and placebo-controlled study design.
The goal of this observational study is to test the effectiveness and safety of Rimegepant in the treatment of migraine patients in real world. The main questions it aims to answer are: - [question 1] the effectiveness and safety of Rimegepant in the acute treatment of migraine - [question 2] the effectiveness and safety of Rimegepant in the long-term treatment of migraine. 1. Participants will be asked to take Rimegepant when they need to treat or prevent a migraine attack. 2. Participants will be asked to record the efficacy data at 0.5, 1, 2, 24, 48h post dose and report any AE to evaluate the effectiveness and safety of Rimegepant in the acute treatment of migraine 3. Participants will be asked to track monthly migraine days and the use of Rimegepant, finish 2 PROs during the follow-ups, report any AE to evaluate the effectiveness and safety of Rimegepant in the long-term treatment of migraine.
The goal of this observational analytic study with a cohort desing is to evaluate the epidemiology, risk factors and clinical phenotype of headache during Influenza infection. The study will be done in collaboration with the Healthcare Sentinel Network of Castile and Leon (Red Centinela Sanitaria de Castilla y León, RCSCYL) and the National Influenza Center of Valladolid (CNGV). First, the historical data of the VIGIRA network of the 2010-2022 flu seasons will be analyzed, assessing the epidemiology and risk factors of headache during Influenza infection; and second, a study with a case series design with prospective follow-up will be carried out for the incident cases of the 2022-2023 and 2023-2024 Influenza seasons, evaluating the clinical phenotype and the duration of the headache.
Naltrexone has a dual function as an opioid receptor antagonist and a Toll-Like Receptor-4 (TLR4) antagonist. While primarily approved in a 50 mg tablet for treating opioid and alcohol addiction by blocking opioid receptors, naltrexone's TLR4-blocking effect is also significant. This action reduces the levels of pro-inflammatory cytokines responsible for pain generation, primarily in the trigeminal ganglion and dorsal root ganglia. These sites play a key role in the effectiveness of naltrexone as a pain-alleviating agent. Acetaminophen is the active ingredient in Tylenol, an over-the-counter non-opioid analgesic and antipyretic agent. Both naltrexone and acetaminophen have demonstrated effectiveness in the treatment of acute migraine, physical pain, and emotional pain. However, while naltrexone has demonstrated potential in animal and human studies, confirmatory clinical trials for pain treatment in humans are still lacking. Additionally, it is important to note that around 50% of migraine patients experience co-occurring anxiety. Therefore, this study aims to assess the effectiveness of naltrexone-acetaminophen in treating migraine and co-occurring anxiety compared to each drug alone and placebo. The sponsor has conducted four clinical studies showing promising results of naltrexone-acetaminophen in treating migraine, chronic low-back pain, and emotional pain.
Clinical study participation has historically been heavily biased toward specific demographics. This study will invite several participants to gather a wide range of information on clinical trial experiences for migraine patients. The aim of the study is to identify the factors that limit the ability of a person to enroll in, as well as complete a clinical trial for treatment of migraine. People with migraine who are invited to take part in medical research will benefit from the analysis of the data.
Background: Mood disorders, such as bipolar disorder, can have serious effects on a person s life. People with bipolar disorder are more likely to have heart disease and abuse substances. In this natural history study, researchers would like to learn more about the connection between exercise and mental health in people with and without mood disorders. Objective: To better understand relationships among physical activity, sleep, and mental health. Eligibility: People aged 12 to 60 years with a history of a mood disorder. Healthy spouses and relatives with no mood disorders are also needed. Design: Participants will be in the study up to 2 years. For up to 20 days in a row, at 4 times during the study, participants will: Complete an electronic diary on their smartphone. Participants will answer questions about their mood, health, sleep, and daily activities. Wear an activity monitor, like a wristwatch, that records how much they move. Wear a light sensor, as a necklace, to record the amount of light in their environment. Some participants will do additional tests. Twice during the study, for 3 days in a row, they will: Wear monitors to record their temperature, heart rate, and sleep. Provide saliva samples. Complete cognitive tasks on their smartphone. Participants will visit the NIH clinic 2 times. They will have a physical exam, with blood and urine tests. They will wear a heart monitor. They will ride a stationary bike for 30 minutes. They may have an imaging scan. Some participants will stay overnight. They will go to sleep wearing a cap to measure their brain activity.
The involvement of calcitonin gene-related peptide (CGRP) in the cinnamaldehyde-induced dermal blood flow increase and in the mechanism of action of triptans will be investigated. The capsaicin-induced dermal blood flow will be incorporated as a positive control; histamine skin pricks as a negative control. Changes in dermal blood flow will be measured with laser speckle contrast imaging.
Aim 1. To identify psychophysical and neural factors predicting migraine onset in adolescents Aim 2a. To determine hormonal, psychophysical, and neural changes associated with migraine onset. Aim 2b. To identify the temporal relationships between hormonal, psychophysical, and neural changes preceding vs. following migraine onset. Aim 3. To identify psychophysical and neural factors predicting migraine prognosis in adolescents with migraine.
Migraine is a neurological disease characterized by moderate or severe headache, associated with nausea, vomiting, and/or sensitivity to light and sound. This study will how effective the combination use of ubrogepant and atogepant is in treating adult participants with migraine. Change in migraine activity will be assessed. Urogepant (Ubrelvy) and Atogepant (Qulipta) are approved drugs for treatment of migraine in adults in the US. Approximately 432 adult participants who are prescribed Ubrogepant and atogepant by their doctors will be enrolled in this study in the United States. Participants will receive ubrogepant oral tablets and atogepant oral tablets as prescribed by their physician. Participants will be followed for 30 days. There is expected to be no additional burden for participants in this trial. Participants will attend regular visits during the study at a hospital or clinic according to their routine clinical practice.
