Long-Term Prognosis of Patients with Photosensitive Idiopathic Generalized Epilepsy

Photosensitivity is present in 2-14% of patients with epilepsy and characterized by the photoparoxysmal response (PPR), an abnormal electrophysiologic response to visual stimuli. PPR is defined as a 2-5 Hz generalized spike, spike/slow wave pattern, usually more pronounced in the frontal and paracentral regions, observed during intermittent photic stimulation (IPS) [1]. Clinical photosensitivity refers to the triggering of seizures by flashing lights from natural or artificial light sources [2].
