We describe a 7 year old boy, who presented centro-temporal (C-T) spikes triggered by blinking. The clinical picture was characterized by mild mental retardation and dysmorphisms; epileptic seizures were absent. Karyotype revealed a 13q deletion. EEG showed independent bilateral C-T paroxysmal abnormalities, very increased during sleep. From the age of 5.5 years blinking triggered C-T spikes: neither eye closure nor elimination of visual fixation induced this phenomenon. Rare similar cases are described in literature

Abstract
We describe a 7 year old boy, who presented centro-temporal (C-T) spikes triggered by blinking. The clinical picture was characterized by mild mental retardation and dysmorphisms; epileptic seizures were absent. Karyotype revealed a 13q deletion. EEG showed independent bilateral C-T paroxysmal abnormalities, very increased during sleep. From the age of 5.5 years blinking triggered C-T spikes: neither eye closure nor elimination of visual fixation induced this phenomenon. Rare similar cases are described in literature
