Paroxysmal visual disturbances of epileptic origin and occipital epilepsy in children.
A special form of partial occipital epilepsy clinically resembling migraine and possibly related to the benign focal epilepsies of childhood has recently attracted attention (Gastaut 1982) but its existence is still debated. To approach this problem, in a group of 195 children with idiopathic partial or generalized epilepsy we have studied those who had visual complaints as part of their seizures (twelve children) and those who also had migraine (four children). The clinical and electroencephalographic features of these children were analyzed together with those of another group of thirty children diagnosed as migraine accompagnée in which an EEG had been obtained (3/30, i.e. 10% had paroxysmal spike-waves: one centrotemporal focus, two generalized spike-waves). One child with the type of epilepsy described by Gastaut (1982) as partial benign occipital epilepsy (phosphenes, moving lights, headaches and occipital high voltage biphasic spike-waves blocked by eye opening on the EEG) was found in the epileptic group whereas the other children of this group, including those with associated migraine, had other types of epilepsy. This "new" type of epileptic syndrome can be distinguished from symptomatically resembling entities but its place needs to be further defined.
