PURPOSE: We describe 2 @entity1 , aged 19 years, who experienced a rolandic @entity410 at ages 4 and 5, respectively, together with the interictal EEG features of @entity1654 ( @entity1654 ). In adolescence both @entity1 developed photosensitive occipital @entity410 accompanied by spontaneous and photic-induced occipital EEG paroxysms. METHODS: We have been following 33 @entity1 with a history of @entity1654 , between ages 12 and 28 years (mean 17 years). Twenty-one of these @entity1 had experienced their last rolandic @entity410 before the age of 10 years and 9 of them had been without treatment since age 11 or earlier. In 2 of these 9 @entity1 , other types of @entity410 recurred after remission of @entity1654 . Clinical, EEG, and evoked potential findings on these 2 @entity1 are presented. RESULTS: After having experienced @entity1654 , both @entity1 suffered partial @entity410 from age 12, with @entity1833 , @entity227 , slow head turning, @entity158 , epigastric discomfort, unresponsiveness, and @entity391 . @entity410 onset was related to watching TV or exposure to bright light. EEG showed interictal occipital spikes, and a photoparoxysmal response limited to the occipital lobes. Visual evoked potentials were greatly increased in amplitude. One @entity1 had two @entity227 and remained @entity410 free after 4 years of follow-up, while the other had @entity410 controlled by an association of @entity1092 and @entity2049 . CONCLUSIONS: Clinical and neurophysiological characteristics suggest that these two @entity1 may have presented different age-related expressions within the spectrum of a benign @entity410 susceptibility syndrome rather than sharply distinct @entity302 .
