Migraine

INTRODUCTION: The α6 subunit-containing GABAA receptors (α6GABAA Rs) are highly expressed in the trigeminal ganglia (TG), the sensory hub of the trigeminovascular system (TGVS). Hypo-GABAergic transmission in the TG was reported to contribute to migraine-related behavioral and histopathological phenotypes. Previously, we found that Compound 6, an α6GABAA R-selective positive allosteric modulator (PAM), significantly alleviated TGVS activation-induced peripheral and central sensitization in a capsaicin-induced migraine-mimicking model...

Cholelithiasis and its complications are among the most prevalent and costly medical conditions in the United States. Chronic gallbladder disease can progress into more complicated conditions, such as a cholecystoenteric fistula and, more specifically, a cholecystoduodenal fistula (CDF). Repair of these fistulas is complex and usually performed with an open approach. However, if discovered pre-operatively, they can be referred to a hepatobiliary surgery center, where surgeons have specialized training to do such procedures laparoscopically...

Introduction Osmophobia is hypersensitivity to certain odors. Although osmophobia is a symptom related to migraine, it is also reported in tension-type headache (TTH). Osmophobia is recommended for inclusion in the migraine diagnostic criteria because it increases sensitivity and shows absolute specificity. However, there is no evidence of the association between TTH and osmophobia. This study aimed to evaluate the prevalence and clinical characteristics of osmophobia in a cohort of migraine and TTH patients...

BACKGROUND: OnabotulinumtoxinA (onabotA), is assumed to achieve its therapeutic effect in migraine through blocking activation of unmyelinated meningeal nociceptors and their downstream communications with central dura-sensitive trigeminovascular neurons in the spinal trigeminal nucleus (SPV). The present study investigated the mechanism of action of onabotA by assessing its effect on activation and sensitization of dura-sensitive neurons in the SPV by cortical spreading depression (CSD)...

BACKGROUND: Migraine is an episodic disorder and a frequent form of headache. An impaired balance between free radical production and an impaired antioxidant defense system leading to oxidative damage may play a major role in migraine etiology. We sought to investigate whether dietary antioxidant quality score (DAQS) is associated with migraine intensity and frequency among women suffering from migraine. METHODS: This cross-sectional study was conducted on 265 women...

BACKGROUND: Having previously shown headache disorders to be prevalent in Mongolia, here we elaborate on headache as a public-health concern in this country, reporting symptom burden and headache-attributed impaired participation at individual and societal levels, and conducting a health-care needs assessment. METHODS: The study followed the standardized methodology developed by the Global Campaign against Headache, generating a representative general-population sample through multi-level randomized cluster sampling...

Chronic migraine is a common central nervous system disorder characterized by recurrent, pulsating headaches. However, the extent and mechanisms of hypothalamic involvement in disease progression have not been thoroughly investigated. Herein, we created a chronic migraine mouse model using repeated intraperitoneal injections of nitroglycerin. We performed transcriptomic sequencing on the hypothalamus of mice with chronic migraine and control mice under normal physiological conditions, followed by differential gene set enrichment and functional analysis of the data...

BACKGROUND: Postoperative nausea and vomiting (PONV) is a key driver of unplanned admission and patient satisfaction following surgery. Because traditional risk factors do not completely explain variability in risk, we hypothesize that genetics may contribute to the overall risk for this complication. The objective of this research is to perform a genome-wide association study of PONV, derive a polygenic risk score for PONV, assess associations between the risk score and PONV in a validation cohort, and compare any genetic contributions to known clinical risks for PONV...

OBJECTIVES: We conducted the current systematic review to investigate the association between dietary inflammatory index (DII) and severe headaches or migraine among adults via synthesizing observational evidence. METHOD: We conducted a systematic literature search of observational studies through PubMed, Scopus, and Web of Science databases from inception until July 2024. The PECO framework was implemented to select eligible studies as follows: Population (adults with severe headache or migraine), Exposure (individuals with the highest adherence to a pro-inflammatory diet), Comparison (individuals with the lowest adherence to a pro-inflammatory diet), Outcome (risk of developing severe headache or migraine, headaches frequency, duration, severity, and migraine-related disability)...

OBJECTIVE: To assess changes in real-world use of acute and preventive medications for migraine over a 12-month follow-up period in the United States following initiation of the anti-calcitonin gene-related peptide (CGRP) pathway monoclonal antibody (mAb) erenumab. BACKGROUND: Early assessments of real-world use of acute and preventive medications for migraine after initiation of erenumab have been limited to 6 months of follow-up. METHODS: This retrospective cohort study used data from the IQVIA open-source longitudinal prescription (LRx) and medical (Dx) claims databases...

BACKGROUND: Fasting headaches frequently occur during the first few days of Ramadan, and treatment is challenging because of fasting. OBJECTIVE: This study aimed to evaluate the effect of extended-release paracetamol on preventing fasting headaches. METHODS: A randomized, open-label clinical trial investigated the efficacy of extended-release paracetamol at a daily dose of 1330 mg in preventing fasting headache. Adults aged 18 years and older were recruited through the Clinical Trial Unit at the King Saud University Medical City...

OBJECTIVE: To estimate the number needed to treat and cost per additional responder for atogepant and rimegepant versus placebo for the preventive treatment of episodic migraine (EM) in the United States. BACKGROUND: Migraine has an enormous impact on a person's daily activities and quality of life, and results in significant clinical and economic burden to both individuals and society. It is important to understand the comparative efficacy and economic value of oral calcitonin gene-related peptide receptor antagonists (gepants) for preventive treatment of EM...

INTRODUCTION: Migraine, a debilitating neurological disorder characterized by recurrent headaches, affects over 1.1 billion individuals globally. Diabetes mellitus (DM), a chronic metabolic condition marked by high blood sugar levels, affects 463 million individuals according to the International Diabetes Federation. Our study aimed to evaluate the association between migraine and DM and to identify several demographic, socioeconomic, and lifestyle factors, as well as medical and psychiatric comorbidities, associated with migraine among individuals with DM...

Background This study aimed to analyze the visual field changes and retinal nerve fiber layer (RNFL) thickness during the headache phase of migraine attacks among migraine patients compared with controls. Methodology A prospective, case-control study was conducted at a tertiary care center in Palakkad, Kerala from January 2022 to August 2023. This study included 50 migraine patients and 50 age/gender-matched controls. Adults aged 20-40 years with a more than three-year history of migraine were included in this study and those who had systemic or ocular pathologies were excluded...

Headaches are a common neurological disorder, significantly impacting patients' quality of life. Traditional treatments include pharmacological and nonpharmacological approaches. Osteopathic manipulative treatment (OMT) is a holistic, hands-on technique used by osteopathic physicians to alleviate pain and improve function by addressing musculoskeletal dysfunctions. This review aims to evaluate the effectiveness of osteopathic manipulation in managing headaches, focusing on the different types of headaches, the specific techniques used, and the overall outcomes reported in clinical studies...

Pain arising from trigeminal systems such as headache is common, debilitating, and current treatments (e.g., sumatriptan) are limited. New treatments that target novel mechanisms of action may be required to innovate both short- and long-term pain therapy. Fatty acid amide hydrolase and soluble epoxide hydrolase are two pain-related enzymes that regulate pain and inflammation via independent pathways. We have previously demonstrated that simultaneous inhibition of these enzymes using a novel dual inhibitor alleviates acute inflammatory pain in the hindpaw and does not depress wheel running in rats...

BACKGROUND: Comorbidities negatively impact the course of multiple sclerosis (MS). Identifying them is essential, as they represent potentially modifiable prognostic factors that can adversely influence the disease course. However, comorbidity prevalence remains underexplored in certain populations, including in individuals in Brazil. METHODS: In this cross-sectional study, we describe the frequency of comorbidities and their correlation with MS disability progression in a Brazilian population by reviewing the medical records of patients from a single MS center in Brazil...
