Idiopathic Photosensitive Occipital Lobe Epilepsy
Idiopathic Photosensitive Occipital Lobe Epilepsy (IPOLE) is an idiopathic focal epilepsy, characterized by visually induced seizures, usually starting around puberty.
IPOLE belongs to the Reflex Epilepsies, which are epilepsy syndromes, characterized by specific mode of precipitation (Engel 2001). They include, apart from IPOLE, other forms of Visual Sensitive Epilepsy, Primary Reading Epilepsy and Startle Epilepsy (Engel 2001), the most frequent forms of reflex epilepsies being those with visual sensitivity, in which seizures are provoked by environmental light stimulation.
IPOLE presents with focal seizures, beginning around puberty, and often with secondarily generalized seizures. Attacks are triggered by exposure to visual stimuli, such those generated by television (Michelucci and Tassinari 1993; Guerrini et al. 1998) video games (Guerrini et al. 1998) and, less often by other environmental stimuli such as flickering or...
