Background: Migraine pathophysiology involves a neuronal mechanism that is closely associated with the neuronal activation of peripheral trigeminal nociceptive pathways. It also involves a vascular mechanism that is supported by studies concerning the presence of migraine with aura in various vascular diseases. Migraine is associated with silent infarct-like lesions and white matter hyperintensities (WMHs) that can be encountered during magnetic resonance imaging. In this study, we aimed to demonstrate the migraine-WMH link based on pain lateralization...

BACKGROUND: Reversible cerebral vasoconstriction syndrome (RCVS) is a transient cerebrovascular disorder putatively caused by some immunosuppressive agents. CASE REPORT: We recently encountered a 47-year-old female patient diagnosed with dilated cardiomyopathy who developed RCVS after heart transplantation. A triple-drug regimen consisting of tacrolimus, mycophenolate mofetil, and a corticosteroid was started after surgery. On postoperative day (POD) 11, the patient developed a severe headache, although computed tomography of the head demonstrated no signs of hemorrhage or infarction...

Modern medicine often leaves the history and physical by the wayside. Physicians instead skip directly to diagnostic modalities like MRI and angiography. In this case report, we discuss a patient who presented with migraine symptoms. Auscultation revealed signs of pulsatile tinnitus. Further imaging concluded that it was secondary to a type I dural arteriovenous fistula. Thanks to a proper and thorough history and physical, the patient was streamlined into an accurate and efficient work-up leading to symptomatic relief and quality of life improvement...

Increasing epidemiological evidence suggests an association between migraine with aura (MA) and cardiovascular events. There is experimental as well as clinical evidence implying cerebral microembolism as a potential trigger for MA attacks. Microembolism may also account for some of the ischemic MRI lesions more commonly observed in MA than in general population. Limited size of clinically-silent MRI lesions suggests isolated occlusion of a small vessel. However, it is not known whether selective thrombosis of a small arteriole (e...

OBJECTIVES: White matter hyperintensities (WMHs) are observed in patients with migraine with aura (MWA) and without aura (MWO), but there are a limited number of studies regarding patients with MWA. In this study, we aimed to investigate the cardiovascular risk factors which may play a role in the development of WMHs in patients with MWO. METHODS: This observational, analytical, case-control study was conducted between June 2016 and January 2017. It included 21 patients with MWO who had WMHs on brain MRI and 19 patients with MWO who tested normal on MRI (control group) at the Neurology Department Outpatient Polyclinic, Ankara Training and Research Hospital...

BACKGROUND: Acute cerebellitis is a rare disease with the majority of cases described in children. Little is known about the clinical characteristics and outcome in adults. CASE PRESENTATION: A 37-year-old Caucasian woman presented with headache, nausea, and photophobia, and was diagnosed as having a migraine attack. Two days later, she subsequently returned with aggravated headache, dysarthria and horizontal nystagmus. Magnetic resonance imaging (MRI) showed a swollen cerebellum and hydrocephalus and the patient was diagnosed with acute cerebellitis...

Resting-state functional magnetic resonance imaging (rs-fMRI) is used to interrogate the functional connectivity and network organization amongst brain regions. Functional connectivity is determined by measuring the extent of synchronization in the spontaneous fluctuations of blood oxygenation level dependent (BOLD) signal. Here, we review current rs-fMRI studies in headache disorders including migraine, trigeminal autonomic cephalalgias, and medication overuse headache. We discuss (1) brain network alterations that are shared amongst the different headache disorders and (2) network abnormalities distinct to each headache disorder...

OBJECTIVE: To determine if a brain MRI scan in patients with a diagnosis of migraine, who insist on the performance of imaging, is of more benefit in detecting clinically significant unsuspected structural abnormalities than would be expected by chance. METHODS: This prospective, observational, single center study was performed from January 1, 2010 to December 31,2012 and included 100 subjects with a diagnosis of migraine and a normal neurologic exam. A brain MRI scan was performed on all patients, solely at their request, to detect an unsuspected clinically significant structural lesion...

Neurofeedback is a noninvasive neuromodulation technique employing real-time display of brain activity in terms of electroencephalography (EEG) signals to teach self-regulation of distinct patterns of brain activity or influence brain activity in a targeted manner. The benefit of this approach for control of symptoms in attention deficit disorders, hyperactivity, depression, and migraine has been proven. Studies in recent years have also repeatedly shown this treatment to improve tinnitus symptoms, although it has not become established as routine therapy...

OBJECTIVE: Migraine aura is sparsely studied due to the highly challenging task of capturing patients during aura. Cortical spreading depression (CSD) is likely the underlying phenomenon of aura. The possible correlation between the multifaceted phenomenology of aura symptoms and the effects of CSD on the brain has not been ascertained. METHODS: Five migraine patients were studied during various forms of aura symptoms induced by hypoxia, sham or physical exercise and photostimulation...

BACKGROUND: Multimodal computed tomography imaging (MCTI) is increasingly used for rapid assessment of acute stroke. We investigated characteristics and final diagnoses of patients treated with recombinant tissue plasminogen activator (rt-PA) while admission imaging was unremarkable. METHODS: From our prospectively collected stroke database (2013-2016), we identified consecutive patients treated with rt-PA on the basis of an unremarkable brain MCTI and assessed with a 24-hour follow-up brain magnetic resonance imaging (MRI)...

BACKGROUND: Stroke is a major cause of disability in the United States. A portion of patients presenting with stroke-like symptoms in the emergency room who receive tissue plasminogen activator (tPA) do not end up having a true stroke, leading to unnecessary health-care costs. The aim of our study is to identify those patients who have a high likelihood of experiencing a stroke mimic using a novel stroke mimic score and to identify a cutoff point with a high specificity of ruling in stroke mimics...

BACKGROUND: Risk of multiple sclerosis (MS) is influenced by environment and genetics. Infant breastfeeding appears protective against some childhood autoimmune disorders, but its impact on risk of MS in childhood is unknown. The objective of this study is to analyze the association of breastfeeding in infancy on future risk of pediatric-onset MS. BASIC PROCEDURES: Biological mothers of 36 consecutive pediatric-onset MS patients completed a questionnaire on history of breastfeeding and various birth and demographic factors...

PURPOSE OF REVIEW: This review aims to provide an overview of the most recent and significant functional neuroimaging studies which have clarified the complex mechanisms underlying migraine pathophysiology. RECENT FINDINGS: The recent data allow us to overcome the concept of a migraine generator suggesting that functional networks abnormalities may lead to changes in different brain area activities and consequent reduced migraine thresholds susceptibility, likely associated with higher migraine severity and burden...
