The role of the Wada test in the surgical treatment of temporal lobe epilepsy: An international survey

Role of the Wada test and functional magnetic resonance imaging in preoperative mapping of language and memory: two atypical cases

“…However, there has been an increasing trend worldwide to forgo the procedure due to its costly nature (Baxendale et al, 2008) and complications (Wang, Peters, de Ribaupierre, & Mirsattari, 2012). Based on a sample of 74 patients who underwent Wada testing, Loddenkemper, Morris, and Möddel (2008) reported that the procedure is associated with up to 10.9% of minor and major complications.…”

“…Use of the Wada test is declining due to the attendant risk of complications, such as cerebrovascular events (1.3%; Willinsky et al, 2003). While over 95% of epilepsy surgery centers in the world used the Wada procedure in 1993 (Rausch et al, 1993), this rate has progressively declined with functional magnetic resonance imaging (fMRI) replacing Wada testing for language lateralization (Baxendale, Thompson, & Duncan, 2008;Binder, 2011). Some authors have argued that in patients who are righthanded, have solid verbal memory, and right temporal lesions, the Wada is likely unnecessary (Kemp, Wilkinson, Caswell, Reynders, & Baker, 2008).…”

The Wada memory test and prediction of outcome after anterior temporal lobectomy

“…[37][38][39] The issue is complicated by the varied methodology applied to Wada testing by different centers and examiners. Further comprehensive studies are necessary in order to re-evaluate the relevance of Wada tests.…”

Presurgical Assessment of Patients with Refractory Temporal Lobe Epilepsy

“…For example, the ability to predict the development of an amnesic syndrome differs from the ability to identify patients at risk of significant impairment of memory for specific material, verbal or nonverbal, that although amnesic syndrome is not considered fully established, has the sufficient severity to limit vocational options and other aspects of quality of life for patients, that deserve the neuro-rehabilitation plan. In our experience, the IAP provides valuable information not only for hemispheric dominance of functions, but also because in conjunction with other diagnostic evaluations can support the surgical decision regarding: lateralization, localization, cognitive risk, surgical planning, extent of resection, seizure management and neuro-rehabilitation (Galeano, 2011;Wada, 2008;Baxendale, 2008).…”
