Hemiplegic migraine (HM) is a rare migraine with aura; it can be familiar or sporadic. A 46-years-old man presented left migraine followed by right hemiparesis with bilateral plantar flexion of cutaneous plantar reflex (CPR). Brain CT and CT-angiography were normal. The next day patient got worse. The EEG showed left fronto-temporal cuspidate delta waves and brain MRI showed a minimal hyperintensity at T2-sequences in the left frontal cortex with a minor representation of the cortical veins at susceptibility weighted imaging sequences...

Several studies report the presence of white matter lesions on brain magnetic resonance imaging in patients with migraine. The aim of our study was to detect the entity of white matter T2-hyperintensities in 90 high selected patients affected by migraine with aura, compared to a group of 90 healthy controls. We found no significant difference of incidence of white matter alterations comparing these two groups.

A few clinic-based magnetic resonance imaging studies report an increased risk of signal abnormalities in migraineurs brain's white matter, especially in migraine with aura subjects. A vascular genesis has been hypnotized and migraine with aura was considered an independent risk factor for stroke. Available data of magnetic resonance imaging alterations are often nonspecific and sometimes controversial. The aim of our study is to investigate migraine with aura patients with standardized brain magnetic resonance imaging to detect and to quantify the presence of white matter lesions and to analyze their relation with clinical data...

Due to the clinical picture and also based on early imaging data (Weiller et al. Nat Med 1:658-660, 1995), the brainstem and midbrain structures have been intensely discussed as possible driving or generating structures in migraine. The fact that the brainstem activation persisted after treatment makes it unlikely that this activation was only due to increased activity of the endogenous anti-nociceptive system. It was consequently (and somewhat simplifying) coined the "migraine generator". Since then several studies have focussed on this region when investigating episodic, but also chronic migraine...

In the past few decades, the so-feared botulinum toxin has conversely acquired the role of a ever more versatile therapeutic substance, used in an increasing number of pathological situations, including chronic headache and more precisely in the prophylaxis of chronic migraine. The medical use of botulinum toxin allowed to better understand its multiple mechanisms of action. Investigations about the pathophysiology of primary and secondary headaches has shown a series of common biological elements that frequently are also targets of the action of botulinum toxin...

Rubinstein-Taybi Syndrome (RSTS) is an autosomal dominant disorder that is classically characterized by prenatal and postnatal growth restriction, microcephaly, dysmorphic craniofacial features, broad thumbs and toes, and intellectual disability. We describe the first reported case of a pituitary macroadenoma associated with RSTS. A 39-year-old Caucasian female with a past medical history of RSTS diagnosed at age two was found to have a gadolinium-enhancing pituitary mass on magnetic resonance imaging (MRI) of the brain three years ago during workup for migraine-like headaches...

BACKGROUND: Although migraine is one of the most investigated neurologic disorders, we do not have a perfect neuroimaging biomarker for its pathophysiology. One option to improve our knowledge is to study resting-state functional connectivity in and out of headache pain. However, our understanding of the functional connectivity changes during spontaneous migraine attack is partial and incomplete. CASE PRESENTATION: Using resting-state functional magnetic resonance imaging we assessed a 24-year old woman affected by migraine without aura at two different times: during a spontaneous migraine attack and in interictal phase...

The migraine aura is characterized by transient focal cortical disturbances causing dramatic neurological symptoms that are usually followed by migraine headache. It is currently not understood how the aura symptoms are related to the headache phase of migraine. Animal studies suggest that cortical spreading depression, the likely mechanism of migraine aura, causes disruption of the blood-brain barrier and noxious stimulation of trigeminal afferents leading to activation of brainstem nuclei and triggering of migraine headache...

Introduction In the CAMERA population-based MRI study, migraineurs below the age of 50 had decreased T2-values indicative of increased iron deposition in several deep brain nuclei. Longer migraine history was associated with lower T2-values, suggesting an association between migraine attacks and iron accumulation. In the present nine-year follow-up study of the CAMERA cohort we re-measured the T2-values in deep brain nuclei to assess the evolution over time. Methods Baseline and follow-up T2-values measured in several basal ganglia of 128 participants (38 control, 90 migraine) were analyzed using quantitative T2 measurements and multivariate regression analysis...

Migraine auras are typically visual in nature but can manifest as disturbances in somatosensory, auditory, and olfactory senses. Reports of multiple sensory auras are rare in the literature, but their existence may offer novel insights into the pathogenesis of this highly common yet complex neurological condition. Here we report a case of multiple sensory auras involving somatosensory, auditory, and olfactory disturbances in a patient with migraine without visual manifestations. A 45-year-old woman with a 20-year history of migrainous headaches presented with complaints of rightsided facial and hand numbness and paraesthesia...

Introduction The International Classification of Headache Disorders 3rd edition beta (ICHD-3 beta) gave alternative diagnostic criteria for 1.2 migraine with aura (MA) and 1.2.1 migraine with typical aura (MTA) in the appendix. The latter were presumed to better differentiate transient ischemic attacks (TIA) from MA. The aim of the present study was to field test that. Methods Soon after admission, a neurologist interviewed 120 consecutive patients diagnosed with TIA after MRI or CT. Semi-structured interview forms addressed all details of the TIA episode and all information necessary to apply the ICHD-3beta diagnostic criteria for 1...

BACKGROUND: Studies have suggested that contact between opposing mucosal surfaces in the nasal wall and cavity can be a target of the surgical treatment of migraines. Unfortunately, not enough is known about the role of nasal pathology in the pathogenesis of this condition. The co-existence of further rhinological disorders can be an impediment to defining the cause and effect of anatomical variants. The authors compared the MRI scans of migraine- and non-migraine patients (MPs and NMPs, respectively) to determine the prevalence of such mucosal contact points in order to extrapolate whether there is a significant association with migraines...

The use of magnetic resonance imaging (MRI) for evaluation of headache remains excessive among physicians across many specialties according to both the American Headache Society and the American College of Radiology, despite recent attempts at limiting overuse of imaging and procedures. As part of the Choosing Wisely campaign, both of these organizations have explicitly recommended against imaging in patients with uncomplicated or typical migraine headaches. Yet, the practice nevertheless remains prevalent, with estimates ranging from 12...
