Category: Epilepsy/Seizures
Keyword 1: test development
Keyword 2: asymmetry
Objective:
Although the pharmacologic inactivation of a vascular territory to transiently inactivate brain function in the distribution of the injected artery was first introduced by Gardner in 1941, Wada initially developed his technique of amobarbital intracarotid amobarbital administration to reduce cognitive side effects of electroconvulsive therapy (ECT) by anesthetizing the language dominate hemisphere during ECT. Wada introduced the approach of intracarotid amobarbital injection to the Montreal Neurological Institute In 1954 to evaluate cerebral language dominance in epilepsy surgery candidates, which was subsequently modified by Milner to assess the risk of postoperative amnesia using the reversible lesion design to mimic the effects of surgical resection on memory outcome. This presentation will trace the historical developments of Wada testing and its continuing influence on our understanding of brain-behavior relationship.
