Combined activation of the EEG with brietal and pentetrazol

A group of 101 activations with Brietal and Pentetrazol are reported. Although Brietal proved to be of value in the investigation of all forms of epilepsy, with 55% positive results, there remained groups of patients in whom there was still a call for greater diagnostic precision. Pentetrazol was tried in 21 of these patients with 66% positive activation. It was found that the two agents together were successful in 72% of the patients. Both also add valuable negative evidence in suspected functional fits.
