Abstract
• A patient had seizures triggered by spontaneous blinking associated with the act of beginning to speak. Diffuse paroxysmal discharges in the EEG appeared when the patient was blinking in darkness or in bright light. Closing the eyes voluntarily, on command, or as a reflex reaction produced this response very infrequently. During intermittent photic stimulation the epileptic discharges were accompanied by myoclonic jerks. The act of beginning to speak was linked with spontaneous blinking and EEG changes and was accompanied consistently by seizures. These were characterized by a peculiar stuttering and an absencelike impairment of consciousness. Seizures have been controlled well using clonazepam and valproic acid.
