ABSTRACT. Reflex seizures are evoked by a specific afferent stimulus or by activity of the patient and are divided into those characterized by generalized seizures and those principally manifested by focal seizures. Reflex epilepsies are syndromes in which all epileptic seizures are precipitated by sensory stimuli. Three categories of reflex seizures encountered clinically include pure reflex epilepsies, reflex seizures that occur in generalized or focal epilepsy syndromes that are also… Expand

Paper Mentions

Reflex Epilepsy
TLDR
Reflex seizures (RS) are epileptic events that are objectively and consistently elicited in response to a specific afferent stimulus or by an activity of the patient, with or without secondary generalization. Expand
Reflex epilepsy: a review
TLDR
This review briefly introduces reported reflex epileptic seizures, their clinical features and management, and research in this area may possibly reveal some underlying pathophysiology of epileptic phenomena in the brain. Expand
SYN1 Gene Mutation in a Child with Focal Epilepsy and Reflex Bathing Seizures
Reflex seizures are evoked by a specific afferent stimulus or activity. The pathophysiology of reflex seizures is thought to be hyperexcitability of cortical or subcortical neuronal areas thatExpand
Clinical, neuroradiological, and electroencephalographic findings of reflex epilepsies
TLDR
In this hospital-based study, reflex epilepsy frequency was 5% and cranial imaging was mostly found to be normal, as stated in the literature, however, patient histories revealed an unexpectedly high rate of head trauma before seizure onset and a family history of epilepsy. Expand
Micturition-induced seizures: a rare form of reflex epilepsy.
TLDR
A midcentral ictal focus is in keeping with previous reports of this area as a potential epileptogenic center for micturition-induced seizures. Expand
Epileptic seizures and hippocampal damage after cuprizone-induced demyelination in C57BL/6 mice
TLDR
The present data suggest a potential role of the hippocampal formation for seizures occurring as a consequence of neuronal damage secondary to CNS demyelination in mice fed with 0.2% cuprizone. Expand
The startle syndromes: Physiology and treatment
TLDR
Startle syndromes are paroxysmal and show stimulus sensitivity, placing them in the differential diagnosis of epileptic seizures, and stimulus‐induced disorders cover a broad range of epilepsy and nonepileptic disorders, and distinguishing the two can be difficult. Expand
Clinical and electrophysiological findings in patients with phenylketonuria and epilepsy: Reflex features
TLDR
It is emphasized that reflex clinical features may be observed in this metabolic disease, and focal epileptiform abnormalities and asymmetry may be present in electrophysiological evaluation besides the rare association with HS. Expand
Reflex gelastic–dacrystic seizures following hypoxic–ischaemic encephalopathy
TLDR
A young woman who presented with somatosensory-evoked gelastic-dacrystic seizures had a positive history of perinatal insult substantiated by MRI findings and Hypoxic–ischaemic encephalopathy as the cause of gelastic–dacystic seizures was reported. Expand
[Rare cases of reflex epilepsy in patients with gliomas of the left hemisphere].
TLDR
The cases of symptomatic reflex epilepsy in patients with left hemisphere tumors with past medical history of spontaneous vegetative seizures, and a 23-year-old man who has had tonic-clonic seizures of the tongue with rare secondary localization, are presented. Expand

Cortical triggers in generalized reflex seizures and epilepsies.
TLDR
Functional imaging and other methods have contributed to understanding how seizures arise, and patients with generalized reflex seizures appear to have regions of cortical hyperexcitability overlapping or coinciding with areas physiologically activated during specific sensory stimulations and cognitive or motor activities. Expand
Reflex seizures induced by calculation, card or board games, and spatial tasks
TLDR
The clinical and EEG findings in all 25 patients support the diagnosis of primary generalized epilepsy and the genetic features are those of a primary generalized epileptic disorder without evidence for a specific inheritance of reflex sensitivity. Expand

TLDR
An appreciation for the fact that epilepsy is not merely an increase in excitation and/or a decrease in inhibition, but a variety of complicated neuronal interactions in different patients, or even at different times in the same patient or same seizure, is essential to the development of effective treatments to control epileptic seizures and prevent their consequences. Expand
Writing epilepsy: A neurophysiological, neuropsychological and neuroimaging study
TLDR
Some evidence is provided supporting the hypothesis that the mechanism underlying writing-triggered seizures may be a generalized seizure process, with a focal cortical trigger zone, presumed to be the left frontal lobe as suggested by clinical and fMRI data. Expand
Startle provoked epileptic seizures:features in 19 patients.
TLDR
The imaging abnormalities identified in patients with startle provoked epileptic seizures suggest that SPES are often due to occult congenital lesions and that the lateral premotor and perisylvian cortices are important in this phenomenon. Expand
Movement epilepsy in the monkey with an experimental motor focus.
TLDR
In the monkey with an alumina focus in the primary motor area, proprioceptive afferents are crucial in triggering or modulating seizures, and reversible exclusion by curarization results in either regularization of spontaneous seizure frequency and duration or in their subtotal suppression. Expand
Reflex seizures.
TLDR
This article reviews established reflex syndromes, including data gleaned from the application of intensive monitoring, as well as animal models, which offer insight into sensory and cognitive processing. Expand
[Animal models of epilepsy and experimental seizures].
Animal models of epilepsy are essential for the search of new effective antiepileptic drugs. Moreover they may lead to the discovery of the basic neuronal dysfunction(s) which underlies humanExpand
The variants of reading epilepsy. A clinical and video-EEG study of 17 patients with reading-induced seizures.
TLDR
It is proposed that ictogenesis in reading or language-induced epilepsy is based on the reflex activation of a hyperexcitable network that subserves the function of speech and extends over multiple cerebral areas on both hemispheres. Expand
Photosensitivity in epilepsy. Electrophysiological and clinical correlates.
TLDR
This thesis describes the results of an extensive and standardized study of 100 consecutive photosensitive patients with special emphasis on the clinical history, the seizure history and the electrophysiological findings. Expand
