Television‐induced electronegative photoparoxysmal response: an extratemporal seizure mimic?
Epileptic Disorders, 2021AbstractVideo‐EEG monitoring is an established gold‐standard procedure for diagnosis and differentiation of epileptic and non‐epileptic seizures. Epilepsy misdiagnosis, to which factors such as EEG artifact misinterpretation contribute to, is common, and can have long‐lasting iatrogenic repercussions to the clinical management of affected patients ...

Clinical correlations of photoparoxysmal responses
Electroencephalography and Clinical Neurophysiology, 1990Reilly and Peters (1973) reported that photoparoxysmal responses (PPRs) that outlasted the stimulus correlated significantly with seizures as compared to self-limited PPRs. However, they defined a wide range of activity, including occipital spikes and slow wave bursts, as PPR.

Prognosis of photoparoxysmal response in nonepileptic patients
Neurology, 1993Photoparoxysmal response (PPR) is sometimes incidentally encountered in EEGs performed for evaluation of nonepileptic symptoms. We conducted the first long-term study of a cohort of nonepileptic patients to determine their risk of having seizures subsequent to incidental recording of PPR. After 6 to 12 years (mean, 9 years), none of the 33 patients had

Cortical Thickness Changes Associated with Photoparoxysmal Response
Brain Topography, 2014Photoparoxysmal response (PPR) is an EEG trait of spike and spike-wave discharges in response to photic stimulation that is closely linked to idiopathic generalized epilepsy (IGE). In our previous studies we showed that PPR is associated with functional alterations in the occipital and frontal cortices.

Juvenile fire setting and the photoparoxysmal response
Annals of Neurology, 1992AbstractWe report on 3 boys with fire setting, photoparoxysmal responses to intermittent photic stimulation, and temporal lobe electroencephalographic abnormalities. Fire setting resolved and behavior improved with administration of anticonvulsants.

Photoparoxysmal responses in children with chromosomal aberrations
Epilepsy Research, 2006Electroencephalographic (EEG) anomalies and epilepsy are commonly observed in the clinical picture of patients with chromosomal aberrations. However, no investigations have been performed on the relationship between chromosomal disorders and photoparoxysmal response (PPR).

Association of BRD2 polymorphisms with photoparoxysmal response
Neuroscience Letters, 2006A trait locus for electroencephalographic photoparoxysmal response (PPR) has been mapped to the chromosomal region 6p21 near a susceptibility locus for juvenile myoclonic epilepsy (JME). Linkage disequilibrium mapping revealed strong associations between JME and polymorphisms of the gene encoding the bromodomain-containing protein 2 (BRD2). The present

Photoparoxysmal response in late infantile neuronal ceroid-lipofuscinosis
Pediatric Neurology, 1998A patient presented with rapid developmental regression whose MRI findings suggested a leukodystrophy, but nerve, muscle, skin, and bone marrow biopsies were unrevealing. A characteristic photoparoxysmal response on electroencephalogram provided an important clue for the correct diagnosis of late infantile neuronal ceroid-lipofuscinosis, which was ...
