The EEG Photoparoxysmal Response

Pediatric Neurology Briefs, 2008
Types of photosensitivity, prevalence and other characteristics of the photoparoxysmal response (PPR), associated seizures, effect of video games, and drug therapy are reviewed by the director of electroencephalography at the University of Illinois ...

Photoparoxysmal responses [PDF]

Arquivos de Neuro-Psiquiatria, 1990
Sixty-five outpatients with photoparoxysmal response (PPR) during routine EEG were studied. The PPR showed prevalence in women (75.4%). Seizures were found in 66.1% of cases.

Diagnostic utility of specific abnormal EEG patterns in children for determining epilepsy phenotype and presence of structural brain abnormalities [PDF]

Heliyon, 2022
Objective: Estimate sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of EEG findings: centrotemporal spikes, photoparoxysmal response, asymmetric photic driving, and asymmetric sleep spindles, for epilepsy ...

Suppression of the photoparoxysmal response in photosensitive epilepsy with cenobamate (YKP3089). [PDF]

Neurology, 2019
To evaluate the effect of cenobamate in patients with photoparoxysmal-EEG response (PPR) to intermittent photic stimulation (IPS) as proof of principle of efficacy in patients with epilepsy.In this multicenter, single-blind study, adults with photosensitive epilepsy, with/without concomitant antiepileptic drug therapy, underwent IPS under 3 eye ...

Patterns of intrahemispheric propagation in pediatric photoparoxysmal response [PDF]

Seizure: the Journal of the British Epilepsy Association, 2017
The photoparoxysmal response (PPR) is the most important EEG indication of photosensitivity (PS). It may be elicited by intermittent photic stimulation (IPS). PS mostly affects young individuals, with adolescent females at greatest risk. The diagnosis of PS is based on visual EEG assessment. To date, no objective test of PS has been established.Here we

Case report: A relevant misdiagnosis: Photosensitive epilepsy mimicking a blinking tic [PDF]

Frontiers in Pediatrics, 2022
Blinking in children is most frequently a functional and transient symptom. Nonetheless, sometimes it is the first clinical manifestation of a neurological disorder.

Wavelength Dependence of Photoparoxysmal Responses in Photosensitive Patients with Epilepsy [PDF]

Epilepsia, 1999
Summary:Purpose: We tried to specify the relation between the photoparoxysmal response (PPR) and the wavelength spectra of flashing light in various photosensitive epileptic syndromes in the physiologic state.Methods: Intermittent photic stimulation (IPS) by a Grass PS22 photic stimulator was performed with wavelength‐specific optical filters in ...

Evidence of Sex-Related Pharmacodynamic Differences in Photosensitive Epilepsy Treated with Valproate: Findings from a Retrospective, Observational, Single-Center, Within-Patient, Cohort Study [PDF]

Drugs - Real World Outcomes
Background and Objective Sexual dimorphism in drug efficacy, beyond pharmacokinetics (PK), remains underexplored. Significant sex differences exist in drug metabolism and adverse events, highlighting the need for personalized medicine.
