Sustained visual cortex hyperexcitability in migraine with persistent visual aura [PDF]

Brain, 2011
Persistent aura without infarction, a rare migraine disorder, is defined by aura symptoms that persist for >1 week without radiological evidence of cerebral infarction. To unveil its pathophysiological mechanisms, this study used magnetoencephalography to characterize the visual cortex excitability in persistent aura by comparison with episodic and ...

Characteristics of Migraine Visual Aura

Headache: The Journal of Head and Face Pain, 1997
Visual auras (VAs) of 100 patients with migraine with aura were studied by questionnaire. Visual auras accompanied the patients' first headache (HA) in 39% of patients. Only 19% had VAs with every attack. Patients with VAs over the entire HA history had a high frequency (greater than 50%) of attacks with VA; patients with VA during only part of the HA ...

Perceptive aspects of visual aura

Neurological Sciences, 2009
Visual aura is the most common feature associated with migraine, though it can occur separately. In both cases it often represents a dramatic event, especially for patients who experience it for the first time. Besides, its subjective characteristics may illuminate on the functional architecture of the visual cortex.

Migrainous Visual Auras: A Life History

Headache: The Journal of Head and Face Pain, 2006
We document, as an autobiographical case report, a 72‐year history of migraine and its changing nature. Minor neurological events have waxed and waned, causing repeated searches for pathology, but instead reconfirming an intact central nervous system. In this case it appears that visual migraine auras do not reflect severity of pathology.

Impaired visual inhibition in migraine with aura

Clinical Neurophysiology, 2015
The pathophysiology of migraine with or without aura (MA, MO) is still a matter of debate. We thus studied patients with MA and MO by means of paired-pulse flash-visual evoked potentials (paired F-VEPs). This technique, recently revived, analyses the overall excitability of visual system as detected from the cortical occipital signal.We enrolled 13 ...

Headache and visual aura in an immunocompromised patient

BMJ, 2012
A 38 year old HIV negative South African man was diagnosed in 2007 with stage IVB Hodgkin’s lymphoma. Conventional chemotherapy and radiotherapy had no effect, so in March 2007 he underwent an autologous stem cell transplant. Relapses in 2009 and 2010 resulted in two allogeneic stem cell transplants, after he was conditioned with fludarabine ...

Asymmetry of visual function in migraine with aura: Correlation with lateralisation of headache and aura

Cephalalgia, 2010
Background: Asymmetry of visual phenomena and headache is an important feature of migraine with aura. Methods: This asymmetry was explored by assessment of visual illusions, hemifield spatial contrast detection (HCD) and hemifield pattern reversal visual evoked potentials (HVEPs) in 47 migraineurs with aura (MA), who were not taking ...

Visual migraine aura iconography: A multicentre, cross-sectional study of individuals with migraine with aura [PDF]

Cephalalgia
Introduction Visual disturbances are the most common symptoms of migraine aura. These symptoms can be described systematically by subdividing them into elementary visual symptoms. Since visual symptoms of migraine aura are not easy to describe verbally, we developed a collection of images illustrating previously

Corona Phenomenon as Visual Aura Symptom in Migraine

Cephalalgia, 2001
The visual illusion of a typical corona phenomenon was represented as a visual migraine aura symptom in six of 562 Migraine Art pictures, whereas another five pictures illustrated atypical variants of the said illusion. The extra edges of the corona phenomenon are commonly seen around the perceptual images of objects, but in atypical cases they can ...
