Abstract
Photosensitivity is a phenomenon which is defined more precisely by intermittent photic stimulation that elicits a photoparoxysmal response (PPR). Data about the prognosis of people with PPR are scarce. Pure PPR mostly appears in later childhood and adolescence, has a female preponderance and disappears in many people during the third decade. However, whether or not it disappears is mainly dependent whether or not it is associated with an underlying disease with a benign spontaneous course like Rolandic epilepsy, a good therapy prognosis like juvenile myoclonic epilepsy (which is the epilepsy syndrome with the highest proportion of PPR) or a bad prognosis like progressive myoclonic epilepsies. If PPR persists in epilepsy patients stimulus avoidance and suppression is an appropriate additional approach beyond antiepileptic drug treatment. A typical case is reported.
