Reduced habituation of the nociceptive blink reflex (NBR) is considered a trait marker for genetic predisposition to migraine. In this open-label randomized controlled study, we aimed to test the efficacy of a biofeedback training based on learning of habituation of the NBR (NBR biofeedback) compared with pharmacological (topiramate) treatment and NBR biofeedback plus topiramate treatment in a cohort of migraine without aura patients eligible for prophylaxis. Thirty-three migraine patients were randomly assigned to three months of treatment with: 1) NBR biofeedback, 2) NBR biofeedback plus topiramate 50 mg (b...

BACKGROUND: Migraine-related nausea is associated with significant disability, increased burden of disease, and personal distress. Nausea can lead to delays or avoidance of initiating oral migraine treatment, sometimes resulting in treatment failures and poor outcomes. Nausea is often a symptom of migraine, but nausea may also be a consequence of treatment (ie, treatment emergent nausea [TEN]). Relieving nausea and minimizing TEN are important goals in acute migraine therapy. METHODS: We analyzed data from the COMPASS study, a randomized, double blind, double-dummy, comparative efficacy study that contrasted two active treatments, AVP-825 (breath-powered intranasal delivery of powdered sumatriptan 22 mg) and oral sumatriptan tablets (100 mg)...

INTRODUCTION: Cutaneous allodynia is regarded as an expression of central sensitization in migraine. Although the gold standard is quantitative sensory testing, several practical assessment questionnaires have been developed to assess allodynia in migraine. We aimed to establish the first valid Turkish allodynia assessment questionnaire based on a 12-item allodynia symptom checklist and to evaluate the associated factors. METHODS: The first part of the study included the translation and cultural adaptation of a Turkish version of the checklist...

OBJECTIVE: Migraine headache is a chronic and disabling condition in adults. Some studies have investigated the efficacy of sodium valproate in the treatment of acute migraine, but the effectiveness and tolerability of intravenous valproate as abortive therapy remains unclear. This study aimed to evaluate the effects of sodium valproate and dexamethasone in the treatment of acute migraine. METHODS: We conducted a double-blind randomized clinical trial including 90 patients aged 18 to 65 years with acute migraine headache but no aura...

Background Nitric oxide (NO) has been heavily implicated in migraine. Nitroglycerin is a prototypic NO-donor, and triggers migraine in humans. However, nitroglycerin also induces oxidative/nitrosative stress and is a source of peroxynitrite - factors previously linked with migraine etiology. Soluble guanylyl cyclase (sGC) is the high affinity NO receptor in the body, and the aim of this study was to identify the precise role of sGC in acute and chronic migraine. Methods We developed a novel brain-bioavailable sGC stimulator (VL-102), and tested its hyperalgesic properties in mice...

Objective To determine the efficacy, tolerability, and safety of ascending doses of Adhesive Dermally-Applied Microarray (ADAM) zolmitriptan versus placebo for acute migraine treatment. Background ADAM is a novel patient-administered system for intracutaneous drug administration. In a phase 1 pharmacokinetic study, zolmitriptan administered using ADAM had much faster absorption than oral administration with higher exposure in the first two hours. Methods This was a multicenter, randomized, double-blind, placebo-controlled, parallel-group Phase 2b/3 study evaluating ADAM zolmitriptan 1 mg, 1...

Objective: Effective treatments for insomnia exist, but few physicians treating headaches have routine methods for screening for insomnia. We sought to 1) describe the migraine characteristics and comorbid conditions that can affect sleep and 2) assess their relationships with positive screens on the Insomnia Severity Index (ISI). Methods: This is a retrospective cross-sectional study of the migraine and sleep characteristics of new patients in our headache center (August 15, 2015-October 28, 2015) who were suspected of having migraines based on the new patient intake questionnaire...

Background The diagnosis of transient ischemic attacks is fraught with problems. The inter-observer agreement has repeatedly been shown to be low even in a neurological setting, and the specificity of the diagnosis is modest to low, reflected in a poor separation of transient ischemic attacks and mimics, particularly migraine with aura with its varied symptomatology. In other disease areas, explicit diagnostic criteria have improved sensitivity and specificity of diagnoses. We therefore present novel explicit diagnostic criteria for transient ischemic attacks tested for sensitivity and for specificity against migraine with aura...

PURPOSE: Definite diagnosis of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukocencephalopathy (CADASIL) is mostly done by identification of NOTCH3 mutations. We aimed to develop criteria for selecting patients suspected for CADASIL to undergo genetic testing. SUBJECTS AND METHODS: All subjects were Japanese. We recruited CADASIL patients genetically diagnosed up until 2011 (n=37, Group 1) or after 2011 (n=65, Group 2), 67 young stroke patients (≤55 years old), and 53 NOTCH3-negative CADASIL-like patients...

OBJECTIVE: Previous studies have suggested an association between dry eye and migraine. In a busy ophthalmologist clinic, quick identification of dry eye in migraine sufferers may improve their quality of life. Tear osmolarity is an objective and reliable tool for diagnosing dry eye. It has not been investigated in any population with migraine. Using tear osmolarity and questionnaires, we aimed to explore the relationship between dry eye and clinical symptoms in patients with migraine...

Headache is considered one of the most common complaints affecting all ages: children, adolescents, and adults. A school-based, cross-sectional study was conducted to assess primary headache among high school students aged 16-18 in Grades 11-12, over a period of 3 weeks (May 2017). A questionnaire was designed, in accordance with the International Headache Society's criteria. The Pearson's χ(2) test was computed to show the differences between the variables. Nearly two thirds of the students reported having headache (19...

Alpha-lipoic acid (ALA) is known to lower insulin resistance (IR), which is common among migraineurs. To assess the effect of ALA on headache in migraineurs with IR, we performed an exploratory study on a cohort of patients with migraine, followed at our Headache Center. The 32 patients took ALA 400 mg b.i.d. for 6 months in addition to their on-going treatment. The percentage of patients with a reduction of at least 50% of the attacks was 0.53 (confidence interval [95% CI] 0.36-0.70) at 2 months, 0.56 (0...

INTRODUCTION: Vertigo is classified as peripheral and central. Differentiation of stroke mimics is the most important diagnostic challenge. There is no clinical guidance for the indications of neuroimaging in isolated vertigo patients. The primary aim of this study is to test the diagnostic value of a DWI-MRI protocol to rule-out a central cause in patients with acute isolated vertigo in the ED. METHODS: We prospectively enrolled 144 patients who were presented with isolated vertigo to the ED...

Calcitonin gene-related peptide (CGRP), the most abundant neuropeptide in primary afferent sensory neurons, is strongly implicated in the pathophysiology of migraine headache, but its role in migraine is still equivocal. As a new approach to migraine treatment, humanized anti-CGRP monoclonal antibodies (CGRP-mAb) were developed to reduce the availability of CGRP, and were found effective in reducing the frequency of chronic and episodic migraine. We recently tested the effect of fremanezumab (TEV-48125), a CGRP-mAb, on the activity of second-order trigeminovascular dorsal horn neurons that receive peripheral input from the cranial dura, and found a selective inhibition of high-threshold but not wide-dynamic range class of neurons...

Objective Entropy-based approaches to understanding the temporal dynamics of complexity have revealed novel insights into various brain activities. Herein, electroencephalogram complexity before migraine attacks was examined using an inherent fuzzy entropy approach, allowing the development of an electroencephalogram-based classification model to recognize the difference between interictal and preictal phases. Methods Forty patients with migraine without aura and 40 age-matched normal control subjects were recruited, and the resting-state electroencephalogram signals of their prefrontal and occipital areas were prospectively collected...
