Photosensitivity is a condition detected on the electroencephalography (EEG) as a paroxysmal reaction to Intermittent Photic Stimulation (IPS). This EEG response, elicited by IPS or by other visual stimuli of daily life, is called Photo Paroxysmal Response (PPR). PPRs are well documented in epileptic and non‐epileptic subjects. Photosensitivity rarely in normal individuals evolves into epilepsy. Photosensitive epilepsy is a rare refex epilepsy characterized by seizures in photosensitive… Expand
Photosensitivity: epidemiology, genetics, clinical manifestations, assessment, and management
TLDR
This review focuses on the emerging aspects of photosensitivity, in particular, the new guidelines for intermittent photic stimulation and briefly addresses epidemiological (in non-epileptic and epileptic subjects), genetic, diagnostic, and therapeutic issues. Expand
Effects of clonazepam on self-induced photoparoxysmal responses
TLDR
Electroencephalography revealed marked photoparoxysmal responses (PPR) at 3-20 Hz of photic stimulation and diffuse spike-wave bursts during sleep, and suggested that the behavior of the patient represented self-induction of PPR. Expand
Photosensitivity, visually sensitive seizures and epilepsies
TLDR
The popular term "photosensitive" is used widely and applied to patients with a history of visually induced seizures, with and without a photoparoxysmal response (PPR), and to those with only a PPR. Expand
Clinical and EEG Analysis of Patients With Idiopathic Generalized Epilepsy and Photosensitivity
Introduction: Our aim is to define the electroclinical characteristics of patients with photosensitive idiopathic generalized epilepsy (IGE) and to investigate the differences in seizure types,Expand
Intermittent photic stimulation affects motor cortex excitability in photosensitive idiopathic generalized epilepsy
TLDR
It is confirmed that IPS has a weak influence on the motor cortical output in patients with IGE and PPR, and the loss of the normal shortening of the cSP, otherwise present in healthy subjects in response to IPS, may have a possible protective nature. Expand
Exposure to Intermittent Light During EEG to Support the Diagnosis of Seizure Conditions inPatients at Children
Paroxysmal consciousness disorder in children and teenagers have different reasons, they result from brain function disorders occurring due to different causes, brought about by sudden, excessiveExpand
Electroclinical characteristics and syndromic associations of “eye-condition” related visual sensitive epilepsies—A cross-sectional study
TLDR
These form a unique subset of visual-sensitive epilepsy syndromes with focal or generalized seizure subtypes of idiopathic or symptomatic etiologies, with and without associated photosensitivity. Expand
Relationship Between Fatigue and Photosensitivity
TLDR
Fatigue is associated with photosensitivity, and new perspectives on fatigue are provided. Expand
Photoparoxysmal responses in children with chromosomal aberrations
TLDR
The observations and the review of the literature suggest that patients carrying chromosomal anomalies might have a higher risk for photosensitivity when compared to the normal population. Expand
Investigation of the Relationship Between Clinical and EEG Findings of Photosensitive Epilepsy and GABA Receptor Alpha 1 Subunit (GABRA1) Gene Mutations
TLDR
The lack of mutations in the GABRA1 gene indicates that this gene is not predominantly involved in the etiopathogenesis of PE in the Turkish population, and the research should be extended by increasing the number of patients and by investigating other genes related to GABA. Expand

Role of Dopamine in Generalized Photosensitive Epilepsy: Electroencephalographic and Biochemical Aspects
TLDR
The EEG hallmark of epileptic photosensitivity is the photoconvulsive response, consisting of bursts of generalized and bilaterally synchronous spike-and-wave or polyspike- and-wave activity induced by photic stimulation. Expand

TLDR
Those EEG abnormalities that may be tolerated with low risk of further seizures, and those that are indicative of poor seizure control are described. Expand

Physiology of Human Photosensitivity
TLDR
The topographic distribution of epileptiform EEG activity in response to such stimuli has complemented this approach, leading to the inference that the trigger is cortical and requires sychronised mass action of neurons. Expand
Photosensitivity: genetics and clinical significance.
TLDR
The available data provide evidence for autosomal dominant inheritance of photosensitivity, and the phenomenon could be shown to be a widespread condition being only loosely associated with epilepsy, but more often with symptoms of psychovegetative instability. Expand

TLDR
Forty-five patients who showed occipital spikes as a sole response to IPS have been studied over a 9 year period and are not indicative of epilepsy. Expand
Photosensitive Epilepsy

Photosensitive epilepsy (PE) is the most frequent form of reflex epilepsy and Authors picked out two PE forms based on the analysis of the 16 own observations -with self-induction of the fits. Expand
Occipital spikes and their relation to visual responses in epilepsy, with particular reference to photosensitive epilepsy.
TLDR
It is suggested that the non-specific thalamo-cortical system may be responsible for the genesis of the “epileptogenic” occipital spikes and that increased sensitivity of the occipitals cortex is present in most photosensitive patients. Expand

TLDR
Most patients are sensitive between 15 and 20 flashes per second, particularly if photic stimulation is binocular in the centre of the visual field and if pattern is present in the stimulus, indicating photosensitive epilepsy is one of the secondary generalised conditions. Expand
