62 Possible Causes for Photoparoxysmal Response

  • Benign Adult Familial Myoclonic Epilepsy

    Photoparoxysmal responses (PPR) were noted in 18 (95%) patients with BAFME but 1 (10%) with EGTCS.[] Response 3 progressive myoclonus epilepsy Spastic Paraplegia with Myoclonic Epilepsy[] Generalized epileptiform discharges were recorded in 25% of cases, and a photoparoxysmal response in 31%.[]

  • Juvenile Myoclonic Epilepsy

    responses (PPRs).[] PURPOSE: Juvenile myoclonic epilepsy (JME) is commonly associated with photoparoxysmal response (PPR) with a reported prevalence of 25-42%.[] OBJECTIVE: Up to 30% of people with juvenile myoclonic epilepsy (JME) have photoparoxysmal responses (PPR).[]

  • Idiopathic Generalized Epilepsy

    Other characteristic EEG features include polyspikes, polyspike-wave discharges, occipital intermittent rhythmic delta activity, and photoparoxysmal response.[] PURPOSE: Photosensitivity or photoparoxysmal response (PPR) is an electroencephalography trait that is highly associated with idiopathic generalized epilepsies (IGEs) and[] METHODS: We studied 15 photosensitive IGE patients showing a photoparoxysmal response (PPR) to IPS at 20Hz.[]

  • Unverricht-Lundborg Syndrome

    Background activity kept stable during the course of the disease; generalized paroxysmal discharges and photoparoxysmal response gradually disappeared with a significant difference[] GLOSSARY ANOVA analysis of variance ; KM Kaplan-Meier ; PHT phenytoin ; PME progressive myoclonus epilepsy ; PPR photoparoxysmal responses ; PSW polyspikes and waves ; SSEP[] Left: marked photosensitivity with generalized photoparoxysmal response (PPR). Right: normal background activity, no PPR.[]

  • Neuronal Ceroid Lipofuscinosis 2

    […] with a photoparoxysmal response associated with other epilepsy syndromes.[] EEGs revealed a photoparoxysmal response (PPR) on intermittent photic stimulation in 93% (13 of 14) of patients.[] Unique Characteristics of the photoparoxysmal response in patients with neuronal ceroid lipofuscinosis type 2: can EEG be a biomarker? J Child Neurol. 2016;31:1475-1482.[]

  • Tonic-Clonic Seizure

    Before seizure onset, IPS consistently induced generalized photoparoxysmal responses (PPRs).[]

  • Stroke

    In a carefully screened population of young and middle age asymptomatic adults, Jabbari et al. 12 found an incidence of epileptiform activity, photoparoxysmal response or[]

  • Patau Syndrome

    response and their characteristics in terms of positive frequencies, latencies, grade and duration were noted and analysed.[] METHODS: All EEGs, case-notes, cytogenetic diagnosis and neuroimaging when available were reviewed; data on the occurrence of seizures, epileptiform discharges, photoparoxysmal[]
