Chronic migraine characterized by prolonged bilateral visual and brainstem aura: a case report and literature review [PDF]

BMC Neurology
Migraine aura manifests as various neurological symptoms, which may occur before, during, or persist throughout the headache phase. We report a case of a 30-year-old female patient whose initial symptoms included persistent bilateral photopsia and ...

BOLD repetition enhancement in the orbitofrontal cortex during complex visuospatial processing in migraine without aura: a shift in periaqueductal gray - cortical coupling? [PDF]

The Journal of Headache and Pain
Background Visual discomfort and sensory overload are common complaints in migraine patients without aura (MwoA), even between attacks, yet their neural basis remains poorly understood. We aimed to explore brain activation patterns in response to complex

Localizing value of epileptic visual auras. [PDF]

American Journal of Ophthalmology, 2000
It is difficult to differentiate between seizures of occipital or temporal lobe origin in patients with focal epileptic seizures associated with visual aura. These are often suspected to originate from the visual cortex, which causes reluctance to propose resection as treatment for the affected patient.

Sensory migraine aura is not associated with structural grey matter abnormalities

NeuroImage: Clinical, 2016
Migraine with aura (MA) is characterized by cortical dysfunction. Frequent aura attacks may alter cerebral cortical structure in patients, or structural grey matter abnormalities may predispose MA patients to aura attacks.

Migraine with visual aura associated with thicker visual cortex [PDF]

Brain, 2018
Until recent years it was believed that migraine with aura was a disorder causing intermittent neurological symptoms, with no impact on brain structure. However, recent MRI studies have reported increased cortical thickness of visual and somatosensory areas in patients with migraine with aura, suggesting that such structural alterations were either due

Vision and Hyper-Responsiveness in Migraine

Vision, 2019
: We investigated contrast processing in relation to visual comfort from coloured light in individuals with migraine. In Experiment 1, 24 individuals who experienced migraine with aura (MA), 15 migraine without aura (MO), and 23 healthy controls ...

Migraine Aura—Catch Me If You Can with EEG and MRI—A Narrative Review

Diagnostics, 2023
Roughly one-third of migraine patients suffer from migraine with aura, characterized by transient focal neurological symptoms or signs such as visual disturbance, sensory abnormalities, speech problems, or paresis in association with the headache attack.

Migraine with Persistent Visual Aura: Response to Furosemide [PDF]

Clinics, 2009
Persistent migraine aura without infarction is a rare but well documented condition. According to the International Headache Society (HIS) criteria, this disturbance is defined by the persistence of a migraine aura for more than one week without radiographic evidence of infarction.1 Here we describe the case of an 11-year-old girl suffering from ...

Case report: An EEG captured case of migralepsy/migraine aura-triggered seizures

Frontiers in Neurology, 2022
IntroductionMigraine and epilepsy are common chronic neurological disorders presenting with paroxysmal attacks of transient cerebral dysfunction, followed by subsequent return to baseline between episodes.
