Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary disease of the cerebral small blood vessels characterized by recurrent ischemic strokes, migraine, and progressive cognitive impairment. In patients with CADASIL, in whom subcortical white matter structures are typically involved, epileptic seizures have been rarely reported as an initial clinical symptom. We describe a patient genetically confirmed as having CADASIL who initially presented with a seizure...

SEE SUN ET AL DOI101093/AWW306 FOR A SCIENTIFIC COMMENTARY ON THIS ARTICLE: About 20% of patients with ischaemic stroke have a preceding transient ischaemic attack, which is clinically defined as focal neurological symptoms of ischaemic origin resolving spontaneously. Failure to diagnose transient ischaemic attack is a wasted opportunity to prevent recurrent disabling stroke. Unfortunately, diagnosis can be difficult, due to numerous mimics, and to the absence of a specific test. New diagnostic tools are thus needed, in particular for radiologically silent cases, which correspond to the recommended tissue-based definition of transient ischaemic attack...

Few studies have evaluated whether the retina is involved in migraine through the evaluation of retinal nerve fiber layer (RNFL) examined with ocular coherence tomography (OCT) with conflicting results. Aim of this case-control study is to evaluate the retina and the choroid in migraine. Patients having migraine with aura (MwA) or without aura (MoA) and chronic migraine (CM) were evaluated. Age- and sex-matched normal subjects were selected as healthy controls (HC). Patients and HC were examined with OCT. RNFL, ganglion cell layer (GCL), foveal thickness (FT), choroidal thickness (CT) and total macular volume (TMV) were calculated for right eyes (RE) and left eyes (LE)...

BACKGROUND: Trigeminal sensitization represents a major mechanism underlying migraine attacks and their recurrence. Nitroglycerin (NTG) administration provokes spontaneous migraine-like headaches and in rat, an increased sensitivity to the formalin test. Kynurenic acid (KYNA), an endogenous regulator of glutamate activity and its analogues attenuate NTG-induced neuronal activation in the nucleus trigeminalis caudalis (NTC). The anti-hyperalgesic effect of KYNA analogue 1 (KYNA-A1) was investigated on animal models specific for migraine pain...

Several lines of research support the hypothesis that migraine is a spectrum of illness, with clinical symptoms that vary along a continuum from episodic migraine to chronic migraine. Physiologic changes may result in episodic migraine evolving into chronic migraine over months to years in susceptible individuals. With chronification, headache frequency increases, becoming more disabling and less responsive to therapy. Neurophysiologic and functional imaging research has reported that chronic migraine may be associated with severity-specific metabolic, functional, and structural abnormalities in the brainstem...

PURPOSE OF REVIEW: It is sometimes assumed that children and adolescents with migraine have a psychiatric or behavioral comorbidity, a belief that can be stigmatizing. This review will examine the recent literature addressing this area to determine if pediatric and adolescent migraineurs are at increased risk for psychiatric comorbidity and to discuss management strategies. RECENT FINDINGS: A large systematic review of pediatric and adolescent studies concluded anxiety and depression were not associated with onset of recurrent headaches...

OBJECTIVE: To develop and implement an algorithm for the management of headaches presenting to the emergency department (ED) in order to decrease the frequency of opioid and barbiturate treatment both acutely as well as on discharge. BACKGROUND: Headache is the fifth leading cause of ED visits in the United States. In the case of primary headache, particularly migraine, treatment in the ED can be highly variable. Patients with migraine continue to be treated with opioids more commonly than nonopioid, migraine specific medications...

Background. While electroacupuncture (EA) pretreatment in migraine has been found to attenuate pain and frequencies of attacks, the underlying mechanism of its antinociceptive effect remains poorly understood. Emerging evidence suggests that the serotonin system may be involved in migraine pathophysiology. Method. Forty male Sprague-Dawley rats were randomly assigned to Control, Model, EA, and sham acupuncture (SA) groups. HomeCageScan was used to measure the effects on spontaneous nociceptive behaviors. Radioimmunoassay and high-performance liquid chromatography were used to evaluate the expression of 5-hydroxytryptamine (HT) in the plasma and three-key structure of the descending pain modulatory system...

Migraine is two to three times more prevalent in women than men, and women report a longer attack duration, increased risk of headache recurrence, greater disability, and a longer period of time required to recover. Conditions recognised to be comorbid with migraine include asthma, anxiety, depression, and other chronic pain conditions, and these comorbidities add to the amount of disability in both sexes. Migraine-specifically migraine with aura-has been identified as a risk factor for vascular disorders, particularly in women, but because of the scarcity of data, the comparative risk in men has yet to be established...

Cyclic vomiting syndrome (CVS) is an uncommon, idiopathic disorder defined by recurrent, sudden-onset attacks of repetitive retching and vomiting that are separated by symptom-free intervals. CVS was long regarded as a disorder primarily experienced by children but is now known to present de novo in adulthood. Adult CVS has garnered more research attention over the past 20 years, and these efforts have identified some acute and prophylactic treatments for this disorder. However, CVS still lacks a unifying disease model, and this has hindered the development of new therapies...

The middle meningeal artery (MMA) is a very important artery in neurosurgery. Many diseases, including dural arteriovenous fistula (DAVF), pseudoaneurysm, true aneurysm, traumatic arteriovenous fistula (AVF), moyamoya disease (MMD), recurrent chronic subdural hematoma (CSDH), migraine and meningioma, can involve the MMA. In these diseases, the lesions occur in either the MMA itself and treatment is necessary, or the MMA is used as the pathway to treat the lesions; therefore, the MMA is very important to the development and treatment of a variety of neurosurgical diseases...

Migraine is a common neurovascular disorder, affecting millions of people worldwide. Current guidelines recommend triptans as first-line treatment for moderate-to-severe migraine attacks. Frovatriptan is a second-generation triptan with a longer terminal elimination half-life in blood than other triptans (~26 hours). Three double-blind, randomized crossover preference studies have been recently conducted, assessing efficacy and safety of frovatriptan versus rizatriptan, zolmitriptan, and almotriptan, respectively...

BACKGROUND: Pain freedom at 2 hours and sustained pain response at 24 hours are important outcomes of acute migraine therapy. Some studies have examined rates and predictors of successful treatment outcomes for single attacks in clinical trials. However, little is known about predictors of typical response to acute treatment over multiple attacks in the population. OBJECTIVES: To identify sociodemographic features, headache characteristics, comorbidities and treatment-related factors that predict acute treatment success or failure at 2 hours and 24 hours post dose in a US population sample of persons with episodic migraine...

A 52-year-old woman presented with recurrent, severe abdominal pain. Laboratory tests and imaging were insignificant, and treatment for functional dyspepsia was ineffective. The poorly localized, dull, and severe abdominal pain, associated with anorexia, nausea, and vomiting, was consistent with abdominal migraine. The symptoms were relieved by loxoprofen and lomerizine, which are used in the treatment of migraine. We herein report a case of abdominal migraine in a middle-aged woman. Abdominal migraine should be considered as a cause of abdominal pain as it might easily be relieved by appropriate treatment...

Migraine is a recurrent and commonly disabling primary headache disorder that affects over 17% of women and 5%-8% of men. Migraine susceptibility is multifactorial with genetic, hormonal and environmental factors all playing an important role. The physiopathology of migraine is complex and still not fully understood. Many different neuropeptides, neurotransmitters and brain pathways have been implicated. In connection with the myriad mechanisms and pathways implicated in migraine, a variety of multisystemic comorbidities (e...

A large number of migraineurs have various transient neurological symptoms in the absence of headache at one time or another. Such transient neurological symptoms largely represent the typical migraine auras without headaches. Isolated visual aura is the most common aura in this category. Sensory aura is the second most common aura. However, the literature is sparse regarding isolated sensory aura without headache. Herein, we are reporting two cases of recurrent paraesthesia that fulfilled the International Classification of Headache Disorders (ICHD-3β) criteria of typical migrainous sensory aura without headache...
