Anosognosia during Wada testing
Neurology, 1992Anosognosia, the verbally explicit denial of hemiplegia, is more often reported after right- than left-hemisphere lesions. However, this asymmetric incidence of anosognosia may be artifactual and related to the aphasia that often accompanies left-hemisphere lesions.

Apraxia is the loss of the ability to perform learned skilled movements correctly. In right-handers, apraxia and aphasia are most frequently associated with left-hemisphere lesions. When they are dissociated, however, aphasia is more common in the absence of apraxia than vice versa. There are two hypotheses that can account for this discrepancy: (1) in

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 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,

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 ...

Abstract The Wada test—or intracarotid amobarbital procedure—has a rich history in the evaluation of language and memory among presurgical patients with temporal lobe epilepsy and other conditions affecting the temporal lobes (e.g., brain tumor).
