lüll Non-invasive alternatives to the Wada test in the presurgical evaluation of language and memory functions in epilepsy patients Pelletier I; Sauerwein HC; Lepore F; Saint-Amour D; Lassonde MEpileptic Disord 2007[Jun]; 9 (2): 111-26The cognitive outcome of the surgical removal of an epileptic focus depends on the assessment of the localisation and functional capacity of language and memory areas which need to be spared by the neurosurgeon. Traditionally, presurgical evaluation of epileptic patients has been achieved by means of the intracarotid amobarbital test assisted by neuropsychological measures. However, the advent of neuroimaging techniques has provided new ways of assessing these functions by means of non-invasive or minimally invasive methods, such as anatomical and functional magnetic resonance imaging, positron emission tomography, single-photon emission computed tomography, transcranial magnetic stimulation, functional transcranial Doppler monitoring, magnetoencephalography and near infrared spectroscopy. This paper aims at comparing and evaluating the traditional and recent preoperative approaches from a neuropsychological perspective.|*Language[MESH]|Amobarbital/administration & dosage/pharmacology[MESH]|Brain Mapping/*methods[MESH]|Carotid Artery, Internal[MESH]|Diagnostic Imaging/*methods[MESH]|Dichotic Listening Tests[MESH]|Epilepsy/*diagnosis/pathology/*surgery[MESH]|Functional Laterality[MESH]|Injections, Intra-Arterial[MESH]|Magnetic Resonance Imaging[MESH]|Magnetoencephalography[MESH]|Memory/drug effects/*physiology[MESH]|Neuropsychological Tests[MESH]|Neurosurgical Procedures[MESH]|Positron-Emission Tomography[MESH]|Preoperative Care/*methods[MESH]|Spectroscopy, Near-Infrared[MESH]|Tomography, Emission-Computed, Single-Photon[MESH]|Transcranial Magnetic Stimulation[MESH]|Visual Fields/physiology[MESH] |
