Complications during the Wada test
Epilepsy & Behavior, 2008The intracarotid amobarbital procedure (IAP) is routinely used in the preoperative workup of patients with epilepsy. We previously reported dissections and seizures as complications of this procedure and now have reviewed our cohort for additional complications associated with the IAP.Charts of 677 consecutive patients were reviewed for complications ...

Various doses of pentobarbital (1.25-20 mg) and lidocaine (2.5-20 mg) were injected selectively into the artery of Adamkiewicz and anterior spinal artery of 11 monkeys. Pentobarbital produced an acute paraplegia; lidocaine caused a transient paraplegia followed by hyper-reflexia and muscular fasciculation. Duration of effect varied from 5 to 60 minutes

The base rate of Wada test failure
Epilepsy & Behavior, 2008Although functional brain imaging can lateralize language functioning and has the potential to assess the functional integrity of the mesial temporal lobe memory structures, imaging protocols are not currently available for clinical use. Assessing the risk of post-epilepsy surgery memory decline is an important part of treatment planning, and the Wada ...

The Wada test or intracarotid amobarbital procedure (IAP) consists of the short inactivation of one brain hemisphere due to the injection of amobarbital or another short-acting anesthetic into the supplying internal carotid artery (ICA). During the subsequent inactivation period, neurological functions such as language and memory can be tested to ...

The intracarotid amobarbital or Wada test: unilateral or bilateral?
Acta Neurologica Scandinavica, 2009In the Netherlands, presurgical screening for temporal lobe epilepsy (TLE) includes the intracarotid amobarbital procedure (IAP), consisting of two consecutive injections of amobarbital, ipsilateral and contralateral to the epileptic focus. We studied whether a bilateral IAP has added value to a unilateral, ipsilateral IAP.This population-based study ...

INTRACAROTID AMOBARBITAL PROCEDURE: The Wada Test
Neuroimaging Clinics of North America, 1995Wada testing has been a standard part of temporal lobectomy evaluation since the early 1960s. Although the procedure was initially used to lateralize language function, it was soon modified to assess risk for postoperative amnesia. The use of the procedure has now evolved to include prediction of degrees of memory decline. This use has been criticized,

Anosognosia and confabulation during the Wada test
Neurology, 1997Feinberg et al. proposed that right-hemisphere-damaged stroke patients with anosognosia for hemiplegia (AHP) confabulate seeing stimuli on the left side but those without AHP admit to having inadequate visual information. This study examines the relationship between AHP and confabulation using selective anesthesia of the cerebral hemispheres. Seventeen

Abstract This chapter discusses the origins and development of the Wada test. Wada testing, named after Juhn A. Wada, M.D., is the technique of arterial administration of amobarbital (or other short acting barbiturate) to transiently inactivate brain function in the distribution of the injected artery during which cognitive testing is ...

Propofol as a substitute for amobarbital in Wada testing
Journal of Clinical Neuroscience, 2015We describe a patient with equivocal findings on functional MRI (fMRI), who underwent a propofol Wada test, review the literature on this topic and suggest a protocol for the use of propofol for a Wada test. Although fMRI techniques can usually accurately lateralize language, the Wada test remains the gold standard for preoperative lateralization and ...
