Comorbidity patterns have become a major source of information to explore shared mechanisms of pathogenesis between disorders. In hypothesis-free exploration of comorbid conditions, disease-disease networks are usually identified by pairwise methods. However, interpretation of the results is hindered by several confounders. In particular a very large number of pairwise associations can arise indirectly through other comorbidity associations and they increase exponentially with the increasing breadth of the investigated diseases...

Calcitonin gene-related peptide (CGRP) is a signaling neuropeptide released from activated trigeminal sensory afferents in headache and facial pain disorders. There are a handful of CGRP-targeted therapies currently in phase 3 studies for migraine acute treatment or prevention. Currently, 4 monoclonal antibodies targeting either the CGRP ligand or receptor are being studied for migraine prevention: ALD403 (eptinezumab), AMG 334 (erenumab), LY2951742 (galcanezumab), and TEV-48125 (fremanezumab). Meanwhile, 1 small-molecule CGRP receptor antagonist (ubrogepant, MK-1602) is currently in phase 3 studies for the acute treatment of migraine...

A large body of evidence supports an important role for CGRP in migraine pathophysiology. This evidence gave rise to a global effort to develop a new generation of therapeutics that inhibit the interaction of CGRP with its receptor in migraineurs. Recently, a new class of such drugs, humanized monoclonal anti-CGRP antibodies (CGRP-mAb) were found to be effective in reducing the frequency of migraine. The purpose of this study was to better understand how the CGRP-mAb fremanezumab (TEV-48125) modulates meningeal sensory pathways...

Background Sleep disturbances are closely related to migraine. Nevertheless, information regarding the impact of short sleep duration and poor sleep quality on the clinical presentation of migraine at population level is limited. Methods This study was a nationwide population-based survey on adults aged 19-69 years. Headache frequency (attacks/month) and intensity (visual analogue scale, 0-10) were documented. Short sleep duration and poor sleep quality were defined as average sleep duration <6 h/day and Pittsburgh Sleep Quality Index score >5, respectively...

Post-thoracotomy pain syndrome (PTPS) is a traumatic neuropathy that can affect as many as 50% of patients undergoing thoracotomy. Patients are often refractory to conservative management and may require multiple analgesics for adequate pain control. Botulinum toxin, derived from Clostridium botulinum, has many uses in treating conditions involving spasticity, dystonia, chronic migraine, and a variety of pain disorders including neuropathies. Botulinum toxin type A injections may provide an alternative or adjunct to improve symptom management in patients with PTPS...

In 2015, 20.0% of women and 9.7% of men aged ≥18 years had a severe headache or migraine in the past 3 months. Overall and for each age group, women aged ≥18 years were more likely than men to have had a severe headache or migraine in the past 3 months. For both sexes, a report of a severe headache or migraine in the the past 3 months decreased with advancing age, from 11.0% among men aged 18-44 years to 3.4% among men aged ≥75 years and from 24.7% among women aged 18-44 years to 6.3% among women aged ≥75 years...

Functional connectivity (FC) has been used to investigate the pathophysiology of migraine. We aimed to identify atypical FC between the periaqueductal gray (PAG) and other brain areas in rats induced by repeated meningeal nociception. The rat model was established by infusing an inflammatory soup (IS) through supradural catheters in conscious rats. Quiescent and face-grooming behaviors were observed to assess nociceptive behavior. FC analysis seeded on the PAG was performed on rats 21 days after IS infusion...

We describe a case of a child suffering from alternating hemiplegia with a heterozygous p. E815K pathogenic variant of ATP1A3. The patient started to present abnormal eye movements in the first days of life, followed by the appearance at 2 months of dystonic episodes, and later on, by recurrent episodes of alternating hemiplegia more often on the right side. A severe epilepsy started at the age of 2 years with episodes of status epilepticus since the onset which frequently recurred, requiring admission to the intensive care unit...

Cortical hyperexcitability due to enhanced glutamatergic activity has been implicated in migraine pathophysiology but direct evidence is lacking. Here we assessed glutamate levels and intracellular mobility of glutamate in the visual cortex of migraineurs in-between attacks. We included 50 migraineurs (23 with aura and 27 without aura) and 24 age- and gender-matched non-headache controls. We used proton magnetic resonance spectroscopy (1H-MRS) and diffusion weighted spectroscopy at 7 T with a single volume of interest (2 × 2 × 3 cm) located in the primary and secondary visual cortex...

BACKGROUND AND PURPOSE: Deciphering the cause for a persistent, direction-changing geotropic nystagmus can be difficult. Migraine and light cupula are two possible causes, though can be confused with benign paroxysmal positional vertigo (BPPV) affecting the horizontal semicircular canal. In migraine, the persistent geotropic nystagmus tends to be slow; in light cupula, the nystagmus has been illustrated to beat in the direction opposite that of prone positioning. CASE DESCRIPTION: Here we describe a patient with initial occurrence then recurrence of a high velocity (≥30 deg/sec), persistent direction-changing geotropic nystagmus and vertigo with an intensity variable based on head position, which was difficult to manage...

Cerebral blood flow is an important process for brain functioning and its dysregulation is implicated in multiple neurological disorders. While environmental risk factors have been identified, it remains unclear to what extent the flow is regulated by genetics. Here we performed heritability and genome-wide association analyses of cerebral blood flow in a population-based cohort study. We included 4472 persons free of cortical infarcts who underwent genotyping and phase-contrast magnetic resonance flow imaging (mean age 64...
