A Visual Learning and Memory Test for Preoperative Evaluation of Patients with Temporal Lobe Epilepsy

Abstract

We used a modified version of the visual DCS (mDCS) test to study patterns of learning, free recall, and recognition capacity in patients with temporal lobe epilepsy (TLE) (N = 24) and controls (N = 38). The patients were under consideration for epilepsy surgery. The mDCS differentiated left from right TLE patients in all aspects of visuospatial learning and delayed recall. The mDCS revealed lower performance for TLE patients as compared with controls. The present results indicate that the mDCS may be a preoperative tool to differentiate left from right TLE.

Long-Term Memory Performance in Adult ADHD

“…While the AVLT and the CVLT are based on a list-learning task, the Logical Memory subtest of the WMS-R and the Paragraph subtest of the LAMB examine participants’ ability to recall facts from orally presented stories. In the visual memory domain, the Rey–Osterrieth Complex Figure Test (ROCF; Osterrieth, 1944), the visual reproduction subtest of the WMS-R, and a modified version of the Visual Learning and Memory Test for Neuropsychological Assessment (Diagnosticum für Cerebralschädigung; mDCS; Dige & Wik, 2001) were included. All three tests ask the participants to reproduce abstract figures either with the help of wooden sticks or through drawing.…”

Hemispheric Lateralization Interrupted: Material-Specific Memory Deficits in Temporal Lobe Epilepsy

“…Some have argued that visual-spatial memory is a bilateral process, which may largely be mediated by the verbalizability of the information to be learned (van Asselen et al, 2006). To-date, pre- and post-operative ATLR studies using neuropsychological and neuroimaging techniques have produced a myriad of inconclusive data that support non-lateralized findings, including measures of navigation (Maguire et al, 1996; Jokeit et al, 2001), maze learning (Bohbot et al, 1998; Astur et al, 2002), scene recognition (Maguire and Cipolotti, 1998; Spiers et al, 2001a), plan drawing (Spiers et al, 2001b), abstract design (Piguet et al, 1994; Dige and Wik, 2001), and faces (Hermann et al, 1997; Reminger et al, 2004). Furthermore, a number of standard tests of visuospatial memory, including the Rey–Osterrieth Complex Figure, commonly used in evaluation of mTLE, do not reliably distinguish between left and right mTLE (Lee et al, 2002; McConley et al, 2008).…”

Memoria Visual (Dcs): Neurodesarrollo de la Memoria Figurativa [Adaptation in Children Population of the Visual Learning and Memory Test for Neuropsychological Assessment (DCS): Neurodevelopment of the Figurative Memory]

“…Las lesiones del lóbulo temporal izquierdo se asocian a déficits en el aprendizaje verbal, mientras que del lóbulo temporal derecho generan déficits en aprendizaje no-verbal, si bien esta última asociación es más discutida (Dige y Wik, 2001). En estudios preoperatorios de pacientes con Epilepsia del Lóbulo Temporal (ELT) derecho, se evidencian déficits en aprendizaje visual (Helmstaedter, Pohl, Hufnagel y Elger, 1991) no sin discusión (Pigott y Melner, 1993).…”

“…Incluye la evaluación del número de aciertos, del número total de rotaciones (al menos 30.º , reproducciones en espejo, falsos positivos y aciertos a largo plazo. Una modificación a la DCs original fue realizada por Dige y Wik (2001), quienes presentan 15 figuras (las ocho originales más siete diseños nuevos) durante tres ensayos, siguiendo las instrucciones de administración de los autores (Lezak, Howieson y Loring, 2004) y evaluación a largo plazo.…”
