Photosensitivity in Dravet syndrome is under-recognized and related to prognosis

Highlights • Photoparoxysmal EEG responses (PPR) are very common (42%) in patients with Dravet Syndrome (DS). • PPR in DS occurs at a strikingly young age and seems to be connected with a more severe course. • Repetitive intermittent photic stimulation with optimal protocol increases detection rate...

Zusammenfassung:	Highlights • Photoparoxysmal EEG responses (PPR) are very common (42%) in patients with Dravet Syndrome (DS). • PPR in DS occurs at a strikingly young age and seems to be connected with a more severe course. • Repetitive intermittent photic stimulation with optimal protocol increases detection rate of PPR.
