Decrement of choroid vascularization during spontaneous migraine attacks: An optical coherence tomography angiography study.

Objective: This study aimed to analyze the microcirculation of the macula, the optic nerve, and the choroid in patients with migraine by optical coherence tomography angiography (OCTA) during spontaneous migraine attacks, comparing the findings with scans performed in the interictal period in the same subjects and healthy controls (HCs).

Methods: In this case-crossover design study, patients diagnosed with migraine who underwent an OCTA during a migraine attack were enrolled. A cohort of HCs was recruited for comparison.

Real-world study of adverse events associated with triptan use in migraine treatment based on the U.S. Food and Drug Administration (FDA) adverse event reporting system (FAERS) database.

Background: Triptans selectively agoniste 5-Hydroxytryptamine(5-HT) receptors and are widely used in the treatment of migraine. Nevertheless, there is a dearth of comprehensive real-world clinical research on the safety of triptans. In light of the growing prevalence of migraine, it is imperative to gain a deeper understanding of the true extent of adverse events (AEs) associated with triptans in the clinical management of migraine.

Cyproheptadine Treatment in Children and Adolescents with Migraine: A Retrospective Study in Japan.

Objective: Evidence on prophylactic drugs for pediatric migraine is limited, especially when comorbid conditions contribute to treatment resistance. This study evaluated the efficacy of cyproheptadine in children with migraine and explored the impact of comorbid neurodevelopmental disorders and orthostatic intolerance (OI).

Methods: We retrospectively analyzed pediatric migraine patients treated with cyproheptadine.

Headache disorders in patients with Ehlers-Danlos syndromes and hypermobility spectrum disorders.

Extra-articular symptoms, including headaches, are frequently encountered in patients with Ehlers-Danlos syndrome (EDS) and hypermobility spectrum disorders (HSD), and may be the presenting complaint. Migraine is reported in up to three quarters of patients with symptomatic joint hypermobility, have a higher headache frequency, and an earlier age of onset compared to the general population. Orthostatic headache is an important presentation, and should raise suspicion of an underlying spinal cerebrospinal fluid leak, dysautonomia, and craniocervical pathology, which are all associated with heritable connective tissue disorders (HCTD) including EDS.

Disrupted topologic efficiency of white matter structural connectome in migraine: a graph-based connectomics study.

Objective: To delineate the structural connectome alterations in patients with chronic migraine (CM), episodic migraine (EM), and healthy controls (HCs).

Background: The pathogenesis of migraine chronification remains elusive, with structural brain network changes potentially playing a key role. However, there is a paucity of research employing graph theory analysis to explore changes in the whole brain structural networks in patients with CM and EM.

Cycling sensitivity across migraine phases: A longitudinal case-control study.

Background: Functional neuroimaging studies indicate that central transmission of trigeminal pain may commence up to 48 h prior to the onset of headache. Whether these cyclic changes are associated with somatosensory alteration remains incompletely understood.

Methods: The present study aimed to investigate the temporal progression of somatosensory alterations preceding the onset of a migraine attack.

Plasma pQTL and brain eQTL integration identifies PNKP as a therapeutic target and reveals mechanistic insights into migraine pathophysiology.

Background: Migraine is a prevalent neurological disorder affecting 14.1% of the global population. Despite advances in genetic research, further investigation is needed to identify therapeutic targets and better understand its mechanisms.

A structural analysis of the splice-specific functional impact of the pathogenic familial hemiplegic migraine type 1 S218L mutation on Ca2.1 P/Q-type channel gating.

P/Q-type (Ca2.1) calcium channels mediate Ca influx essential for neuronal excitability and synaptic transmission. The CACNA1A gene, encoding the Ca2.

The PopHEAD study: a population-based, cross-sectional study on headache burden in Norway: methods and validation of questionnaire-based diagnoses.

Background: There is a lack of up-to-date information on the prevalence and burden of headache in Norway. Here we describe the methods and validation of the diagnostic tool of the PopHEAD study, a study designed to determine the prevalence and burden of migraine, tension-type headache, and medication-overuse headache.

Method: PopHEAD is a Norwegian population-based cross-sectional study conducted in Vestfold and Telemark County in 2023.

Harnessing Miniscope Imaging in Freely Moving Animals to Unveil Migraine Pathophysiology and Validate Novel Therapeutic Strategies.

Migraine is a debilitating neurological disorder that affects millions worldwide. Elucidating its underlying mechanisms is crucial for developing effective therapeutic interventions. In this editorial, we discuss the potential applications of one-photon miniscopes, which enable minimally invasive, high spatiotemporal resolution fluorescence imaging in freely moving animals.

Electroencephalographic signatures of migraine in small prospective and large retrospective cohorts.

Migraine is one of the most common neurological disorders in the US. Currently, the diagnosis and management of migraine are based primarily on subjective self-reported measures, which compromises the reliability of clinical diagnosis and the ability to robustly discern candidacy for available therapies and track treatment response. In this study, we used a computational pipeline for the automated, rapid, high-throughput, and objective analysis of encephalography (EEG) data at Cleveland Clinic to identify signatures that correlate with migraine.

Treatment of migraine with aura with osteopathic manipulative treatment: a case report with renewed perspectives.

Migraines make up a significant number of office visits every year, yet their pathophysiology and etiology remain largely elusive. This case report presents a 33-year-old patient who originally presented to the emergency department (ED) as a stroke alert and was later determined to have migraine with aura. The patient experienced an acute onset of headache, dizziness, and new-onset expressive aphasia.

Benefit-risk assessment based on number needed to treat and number needed to harm: Atogepant vs. calcitonin gene-related peptide monoclonal antibodies.

Background: To evaluate the benefit-risk assessment of atogepant and calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs) vs. placebo based on the number needed to treat (NNT) and the number needed to harm (NNH) in a blended episodic migraine and chronic migraine (EM + CM) population.

Methods: The NNT was calculated based on achievement of a ≥ 50% reduction in mean monthly migraine days (MMDs) from baseline across 12 weeks.

An Automated Squint Method for Time-syncing Behavior and Brain Dynamics in Mouse Pain Studies.

Spontaneous pain has been challenging to track in real time and quantify in a way that prevents human bias. This is especially true for metrics of head pain, as in disorders such as migraine. Eye squint has emerged as a continuous variable metric that can be measured over time and is effective for predicting pain states in such assays.

Worldwide availability of medications for migraine and tension-type headache: A survey of the International Headache Society.

Background: In this study, we aimed to evaluate the differing global access to acute and preventive medications for migraine and tension-type headache.

Methods: A custom-built questionnaire created by members of the International Headache Society Juniors Group was sent to International Headache Society members worldwide, including a list of acute and preventive treatments for migraine and tension-type headache. This list was based on evidence-based medicine guidelines.

The Impact of Food Specific IgG Antibodies on Migraine and Its Comorbidities.

Objective: To investigate the differences in headache and comorbidity symptoms between migraine patients with negative and positive food specific IgG antibodies, and explore the correlation between these symptoms with food specific IgG antibodies.

Methods: A total of 129 migraine patients were enrolled. Seven questionnaires were used to gather information regarding the symptoms of migraine, gastrointestinal, depression, anxiety, and sleep.
