Electroencephalographic Study on the Acetonemic Vomiting Associated with Epilepsy

Abstract

Two cases of the acetonemic vomiting associated with epilepsy were studied with the systemic in travenous administration of small dose (1mg/kg) of thiopental sodium.
The following three EEG findings were carefully assessed following immediately the administration of thiopental sodium: (1) the induction and the distribution of the beta rhythms; (2) the behavior of the bilateral spike & wave discharges, present in the baseline EEG; (3) the appearence of focal elements. One case responded with a prompt induction of symmetrical beta rhythms, depression in the occurrence of the bilateral spike & wave discharges, and no focal features. Another case responded with a almost absent beta rhythms diffusely, persistence of the bilateral spike & wave discharges, and no focal features.
The former may be classified according to Lombroso's discription as having primary centrencephalictype (Primary Bilateral Synchrony), and the latter as having cortico-centrencephalic type.
