“…Moreover, some studies did not report learning performance (Dewar, Hoefeijzers, Zeman, Butler, & Della Sala, 2015;Gallassi et al, 2011;Hoefeijzers, Dewar, Dalla Sala, Butler, & Zeman, 2014;Jansari, Davis, McGibbon, Firminger, & Kapur, 2010;Lah, Mohamed, Thayer, Miller, & Diamond, 2014;McGibbon & Jansari, 2013;Narayanan et al, 2012;O'Connor, Sieggreen, Ahern, Schomer, & Mesulam, 1997;Ricci, Mohamed, Savage, Boserio, & Miller, 2015;Tramoni et al, 2011). In others, learning performance was not equated (Bell, 2006;Bell, Fine, Dow, Seidenberg, & Hermann, 2005;Cronel-Ohayon et al, 2006;Giovagnoli, Casazza, & Avanzini, 1995;Holdstock, Mayes, Isaac, Gong, & Roberts, 2002;Lucchelli & Spinnler, 1998;Mameniskiene et al, 2006;Mayes et al, 2003). These omissions or oversights limit the implications of these studies, as the role of subtle acquisition deficits cannot be excluded.…”

“…3 Daamen, Zang, Janszky, & Ebner, 2001;Mameniskiene, Jatuzis, Kaubrys, & Budrys, 2006;Wilkinson et al, 2012); sclerosis in the medial temporal lobe (Mulhert et al, 2011;Wilkinson et al, 2012); and use of anti-epileptic medication (Jokeit, Krämer, & Ebner, 2005) have all been shown to be associated with accelerated forgetting rates in epilepsy patients. However, the extent to which these variables contribute to forgetting is not clear; findings are heterogeneous because of the wide variability of clinical features and cognitive profiles in this population Kwan & Brodie, 2001).…”

“…Reviewing the studies listed in Table 1, approximately half exhibited progressive forgetting soon after learning that eventually became statistically significant at longer delays (Atherton, Nobre, Zeman, & Butler, 2014;Bengner et al, 2006;Butler et al, 2007;Deak, Stickgold, Pietras, Nelson, & Bubrick, 2011;Evans, Elliott, Reynders, & Isaac, 2014;Kemp, Illman, Moulin, & Baddeley, 2012;Mameniskiene et al, 2006;Martin et al, 1991;Mulhert et al, 2011;Mulhert, Milton, Butler, Kapur, & Zeman, 2010;Wilkinson et al, 2012). Other studies showed a divergent pattern of forgetting, although some of these also exhibited ceiling effects (Blake, Wroe, Breen, & McCarthy, 2000;Butler et al, 2007;Butler, Kapur, Zeman, Weller, & Connelly, 2012;Butler & Zeman, 2008a;Evans et al, 2014;Hoefeijzers et al, 2013;Kapur et al, 1997;Manes, Graham, Zeman, de Luján Calcagno, & Hodges, 2005;Mayes et al, 2003;Mulhert et al, 2011;Wilkinson et al, 2012).…”

The notion of 'accelerated long-term forgetting' has often been attributed to disrupted 'late' memory consolidation. Nevertheless, methodological issues in the literature have left this theory unproven, leading some to suggest such findings may be reflective of subtle acquisition or early retention deficits. This study attempts to address such issues, and also to explore which pathophysiological variables are associated with forgetting rates. Eighteen participants with temporal lobe epilepsy (TLE) and eighteen matched controls completed background neuropsychological measurement of immediate and short-delay memory that showed comparable performance, both on verbal and visual tests. Using two novel experimental tasks to measure long-term forgetting, cued recall of verbal and visuospatial material was tested 30 seconds, 10 minutes, one day, and one week after learning. Forgetting of verbal material was found to be progressively faster during the course of a week in the TLE group. For visuospatial memory, participants in the TLE group exhibited faster early forgetting in the first 10 minutes after learning, as indicated by planned comparisons, with comparable forgetting rates thereafter. Our findings provide evidence for two patterns of disruption to 'early' memory consolidation in this population, occurring either at the initial delay only or continuing progressively through time. Differences in how soon after learning accelerated forgetting was detectable were related to factors associated with greater severity of epilepsy, such as presence of medial temporal lobe sclerosis on MRI and use of multiple anti-epileptic agents.

“…This is thought to be due to the accumulation of small neurodegenerative effects of noxious neurochemical agents, abnormal brain electrical events and metabolic disturbances that exhaust the compensatory capacity of brain functions over decades of seizures. Long-term memory impairment adversely affects learning, working abilities and social status, and is therefore of paramount importance to people with epilepsy (Mameniskiene 2006). …”

SummaryCognitive dysfunction is one of the major contributors to the burden of epilepsy. It can significantly disrupt intellectual development in children and functional status and quality of life in adults. Epilepsy affects cognition through a number of mechanisms in complex interrelationship. Cognitive deficits in epilepsy may be treated indirectly through aggressive seizure control using anti-epileptic drugs or surgery, and by treating comorbid conditions such as depression. The beneficial effects of reducing seizures may offset the adverse cognitive side-effects of these therapies. Direct treatment of cognitive impairment in epilepsy mainly involves memory rehabilitation. Other direct treatments are mostly experimental and their evidence base is currently poor.

“…Although a number of studies report AVLT deficits in TLE (10,11) there is evidence that ceiling effects may confound an accurate assessment of memory status in these patients (12). The aim of the current study is to compare the performance of TLE patients with healthy participants on an AVLT in which the probability of ceiling effects is designed to be minimal.…”

On the Underestimation of Auditory Verbal Learning Impairments in Temporal Lobe Epilepsy

2016

Background: The auditory verbal learning test (AVLT) procedure is routinely deployed in neuropsychological investigations to examine learning and memory status in research and clinical cohorts. Concerns however have been raised regarding the susceptibility of the standard AVLT procedure to ceiling effects, which may have adverse consequences for psychometric properties and result in an underestimation of true potential and differences between normal and abnormal scores.
