Reflex epilepsy evoked by specific psychic activity. A case report.

A patient with epileptic seizures and epileptiform EEG abnormalities precipitated by specific type of intellectual activity is presented. Clinical and subclinical epileptic seizures were accompanied by specific EEG discharges--the left parieto-occipito-temporal spike-and-wave complexes with various grade of generalization. On the basis of detailed EEG and activation studies, it is concluded that seizures in this patient were evoked by higher cognitive processes associated with decision making, anticipation and spatial function.
