BACKGROUND Patients with partial epilepsy may report multiple types of aura during their seizures. The significance of the occurrence of multiple auras in the same patient is not known. METHODS The clinical and electrophysiologic characteristics of patients with more than one aura type (abdominal, auditory, autonomic, gustatory, olfactory, psychic, somatosensory, and visual auras), evaluated ...

In 1944, Leão described cortical spreading depression, the phenomenon now widely believed to underlie what some persons with headache perceive as “aura.” Aura is a somewhat misleading term because it can occur before a migraine, during or after a migraine, or occur without any associated headache. It can also occur with many other types of headache, but in clinical practice it is usually in ass...

AURA (Advanced Uncertain Reasoning Architecture) is a generic family of techniques and implementations intended for high-speed approximate search and match operations on large unstructured datasets [1]. AURA technology is fast, economical, and offers unique advantages for finding near-matches not available with other methods. AURA is based upon a high-performance binary neural network called a ...

BACKGROUND Migraine with aura (MA) has been identified as a risk factor for cardiovascular disease. Previous observation has also found higher prevalence of cardiovascular risk factors in migraineurs without aura (MO), but the results have been conflicting. The present study was conducted to assess the association between cardiovascular risk factors and migraine without aura among Iranians. M...

Background As a complex subjective experience, pain processing may be related to functional integration among intrinsic connectivity networks of migraine patients without aura. However, few study focused on the pattern alterations in the intrinsic connectivity networks of migraine patients without aura. Results Thirty-one migraine patients without aura and 31 age- and education-matched health...

Aura and Sindbis viruses are closely related alphaviruses. Unlike other alphaviruses, Aura virus efficiently encapsidates both genomic RNA (11.8 kb) and subgenomic RNA (4.2 kb) to form virus particles. Previous studies on negatively stained Aura virus particles predicted that there were two major size classes with potential T=3 and T=4 capsid structures. We have used cryoelectron microscopy and...

CLINICAL HISTORY This is a 38-year-old G2 right-handed woman seen at 28 weeks gestation for headaches. At the age of 13, she started having migraines with aura that were frequent for several years and then became less so for many years. During her prior pregnancy 3 years ago, she had 3 migraines with aura. She had no other similar headaches until 2 months ago. She reports 9 episodes with 4 occu...

Objective To determine the prevalence, impact, and stability of different subtypes of headache in a 30 year prospective follow-up study of a general population sample. Design Prospective cohort study. Setting Canton of Zurich, Switzerland. Participants 591 people aged 19-20 from a cohort of 4547 residents of Zurich, Switzerland, interviewed seven times across 30 years of follow-up. Main outcome...

BACKGROUND The aim of this study was to investigate the thickness of the retinal nerve fiber layer (RNFL), the ganglion cell layer (GCL), and choroid thickness (CT) in patients who have migraines, with and without aura, using spectral optical coherence tomography (OCT). METHODS Forty-five patients who had migraines without aura (Group 1), 45 patients who had migraines with aura (Group 2), and...
