COMPLEX PARTIAL SEIZURE PROVOCATION BY VASOVAGAL SYNCOPE - VIDEO-EEG AND INTRACRANIAL ELECTRODE DOCUMENTATION

Vasovagal syncope precipitating an epileptic seizure has only rarely b een described. A patient with known intractable complex partial seizur es being evaluated for a left anterior temporal lobectomy experienced a typical seizure with mesial temporal onset precipitated by an observ ed vasovagal episode. This is the first report of a partial epileptic seizure precipitated by vasovagal syncope and the first example of an epileptic seizure induced by syncope in an adult. Video and intracrani al depth electrode and subdural grid recordings documented the event.
