Visual Aura

This paper outlines the historical development of the concept of the visual aura of migraine, from the first comprehensive published description by the physician Hubert Airy, in 1870. Airy’s description of the phenomenon he called “transient hemiopsia” became widely copied and highly influential as a consequence of the language and images that he used in his presentation. This paper outlines the subsequent development of theories of aura from the time of Airy’s publication to the first demonstration of spreading oligaemia by Lautitzen and Olesen in the 1980s.

Olfactory Hallucination

Background Approximately 3.9% children with migraine have olfactory hallucination which was defined as a perception of a smell without the substantial existence of any physical odor. Case We described the first two cases of children with vestibular migraine, presenting visual aura and olfactory hallucination. ​ We reported two children with vertigo, visual aura, and olfactory hallucination before the headache who were responsive to topiramate. Conclusion The clinical description of olfactory hallucination presented some characteristics of migraine aura. Olfactory hallucinations could be inserted as a migraine aura in International Classification of Headache Disorders.

Background: Migraine aura, made up of one or more neurological symptoms arising from the cortex or brainstem, is a complex neurological phenomenon. Visual aura is the most frequent aura manifestation. Studying the subjective components of visual aura makes it possible to identify common characteristics. Objective: To thoroughly describe the characteristics of migraine visual aura in patients with migraine with aura. Methods: We performed a retrospective, descriptive study of the visual aura of 122 migraine patients collected at two headache clinics in the Americas. This study was designed to determine the characteristics of a typical visual aura. Results: The most common features of the visual aura in our study are that it occurs before the headache with a gap of less than 30 minutes, lasts 5 to 30 minutes, has a gradual onset, usually begins peripherally, is unilateral, and shimmers. Furthermore, the location of typical visual aura in the visual field has no fixed relationship to headache laterality, is slightly more often without color, and is often described as small bright dots and zigzag lines. Blurred vision, not typically considered to be an aura phenomenon of cortical origin, is in fact the most frequently reported visual symptom. Conclusions: Migraine visual aura is heterogeneous and pleomorphic, and some of our findings run contrary to common beliefs.

Similarities And Differences

Illusory splitting was illustrated as a visual migraine aura symptom in six of 562 Migraine Art pictures. In this type of illusion, objects or persons appear to be split, along fracture lines of varying form and orientation, into two or more parts that may be displaced and separated from each other. The illusion is strongly associated with the presence of elementary geometric hallucinations. Phenomenological similarities and differences of illusory splitting to the visual perceptual disturbances of fragmentation and mosaic illusion are discussed.

The case of a 42-year-old woman with prolonged migraine visual aura without headache, whose long-lasting episodes of visual aura were successfully controlled by oral sumatriptan, is reported. Effectiveness of sumatriptan was unequivocal, since, after taking sumatriptan, duration of aura would drop from 1.5 h to approximately 20 min. This case suggests that sumatriptan may cross the blood-brain barrier and block spreading depression.

Objective The objective of this review is to describe auditory hallucinations (paracusias) associated with migraine attacks to yield insights into their clinical significance and pathogenesis. Background Isolated observations have documented rare associations of migraine with auditory hallucinations. Unlike visual, somatosensory, language, motor, and brainstem symptoms, paracusias with acute headache attacks are not a recognized aura symptom by the International Headache Society, and no systematic review has addressed this association. Methods We retrospectively studied patients experiencing paracusias associated with migraine at our center and in the literature. Results We encountered 12 patients (our center = 5, literature = 7), 58% were female, and 75% had typical migraine aura. Hallucinations most commonly featured voices (58%), 75% experienced them during headache, and the duration was most often <1 hour (67%). No patients described visual aura evolving to paracusias. Most patients (50%) had either a current or previous psychiatric disorder, most commonly depression (67%). The course of headache and paracusias were universally congruent, including improvement with headache prophylaxis (58%). Conclusion Paracusias uncommonly co-occur with migraine and usually feature human voices. Their timing and high prevalence in patients with depression may suggest that paracusias are not necessarily a form of migraine aura, though could be a migraine trait symptom. Alternative mechanisms include perfusion changes in primary auditory cortex, serotonin-related ictal perceptual changes, or a release phenomenon in the setting of phonophobia with avoidance of a noisy environment.

Cluster Headaches

Introduction: Migraine is a common primary headache and a major cause of disability. In at least a third of migraine attacks, the headache is preceded and/or accompanied by aura and the visual manifestation is the most frequent phenotype. Migraine with aura, a subtype of migraine disorder, are underdiagnosed and undertreated. So, a detailed aura iconography is important for better recognition, prevention and treatment of migraine with aura. Objective: A visual aura art contest was performed by ABRACES (Brazilian Association of Cluster Headaches and Migraines), in order to provide new images for raising awareness among population and professionals and decreasing the gap between diagnosis and treatment. Methods: The contest involved free subscription of drawings, paintings and digital art that expressed realistic results of a visual aura of migraine and answering of a questionnaire. The awards were separated in two categories (painting/drawing and digital art/photography) and amounted up to R$ 5,000. Results: There were 139 participants, 24% men and 76% women. The most common visual aura’s characteristic was the presence of colorful points, and the less frequently was golden. The mean duration of visual aura was 110.6 minutes (450.5 of standard deviation), median of 20 minutes, minimum of 1 minute and maximum of 3600 minutes. 36.7% of the subscribers have only one kind of visual aura and 33.8% answered that have more than one kind. 46,5% said that their visual aura almost never occurs without pain after or while aura and 19% reported that their visual aura always occurs without a headache. Conclusion: Art contests are useful tools for disease awareness. Further actions in disseminating aura images may help migraine aura underdiagnosis and undertreatment.

This is a case of migraine, presenting with the interesting visual aura of a ‘kaleidoscope’: waves with flickering movements made up of a variety of colors (red, blue, green, yellow), commencing laterally and spreading superiorly in the visual field of the left eye. This description is quite similar to a fortification spectrum, which usually expands and spreads in a C-shape fashion over one side of the visual field. Several different possible pathophysiological explanation are shared as well as the common differential diagnoses. In the work up of a patient with visual aura migraine, a comprehensive and detailed history is important, together with the appropriate investigations, in order not to miss any serious syndromes, including stroke syndromes and epilepsy.

This chapter examines the changing trends and best practices for collection development in academic law libraries. It begins by examining the historical development of the law school as a professional school, and the need for academic law libraries to become learning laboratories for educating lawyers and providing them with the tools and resources to practice law. It then charts how law school collections evolved in response to the emergence of electronic legal research resources. The increasing use of electronic databases and the subsequent development of the Internet have led libraries to examine what are the best practices in collection development. Along with internal forces, external influences, such as “Educating Lawyers: Preparation for the Profession of Law,” a report by the Carnegie Foundation calling for more practice and skills-based training, will require academic law libraries to adapt their collections in light of changing trends in legal education and scholarship (Sullivan, Colby, Wegner, Bond, & Shulman, 2007).

To modern writers, the distinctive achievement of twentieth-century jurisprudence can be viewed as its emancipation from the narrow confines of English utilitarianism, and the subsequent development of perspectives rooted in the fundamental values of justice and rights. The central jurisprudential task of the new century is thus the exploration of a deeper, more elusive moral standpoint, the most profound intellectual commitments of which are yet to be fully digested and understood. My aim in this essay is to reveal something of the character of those commitments by considering the relationship of our present thinking about law and morality to its historical development.

Visual Evoked

Pattern reversal visual evoked potentials (PVEPs) were recorded in 20 patients with migraine with aura (MA), 19 patients with migraine without headache (migraine equivalent; ME) during interictal periods, and 34 normal subjects. All migraine patients had hemianopsia or fortification spectra during attacks. In both MA and ME patients of less than 49 years of age, there were significant ( p<0.01) differences in amplitude of PVEPs at the mid-occipital and contralateral to visual aura electrode sites compared to normal subjects. Amplitude of PVEPs in MA and ME showed significant ( p<0.001) increases when recorded soon after attacks, especially within 10 days. There was a significant ( p<0.01) correlation between percentage asymmetries and the duration of illness in both MA and ME. We conclude from our PVEP findings that cortical spreading depression remains the most likely explanation for the migraine visual aura.
