Hohmann L, Jipping JN, Oltmanns F, Holtkamp M. Changes in overlap of subjective and objective cognition over time in epilepsy surgery candidates. Seizure 2024; 119:36-43. [PMID: 38776616 DOI: 10.1016/j.seizure.2024.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 04/12/2024] [Accepted: 05/05/2024] [Indexed: 05/25/2024] Open
Abstract
PURPOSE Subjective and objective cognition often show weak overlap in persons with epilepsy (PWE). Over- as well as underestimation may occur. In particular after epilepsy surgery, objective memory decline is often not subjectively reported. Additionally, studies on how concordance of subjective and objective cognition changes over time are missing. Therefore, we study the extent of concordance in operated and non-operated PWE over time. METHODS Candidates for resective epilepsy surgery were assessed between 03/18 and 12/20 (T1) with self-report questionnaires and underwent a neuropsychological examination. For 21 operated as well as 27 non-operated PWE follow-up data was obtained one to three years later (T2). Concordance of attention and memory were compared between groups and time points. Moreover, reliable change was calculated and compared between groups. RESULTS Of the total sample, 42 % rated their attention performance realistically and 25 % showed memory concordance. Differences in patterns of over- and underestimation between groups and over time occurred for attention, but not for memory. Overestimation of memory was more frequent in operated than non-operated PWE, especially at T2 (67% vs. 11 %). In the operated group, we mainly observed reliable improvement in subjective cognition and decline in objective memory, whereas non-operated PWE showed more frequently decline of simple attention. Reliable subjective and objective change did not co-occur. CONCLUSION Concordance of subjective and objective cognition is low. Over- as well as underestimation may persist over time. Domain-specific perspectives are necessary. Tendencies of operated PWE to develop overestimation of memory after surgery should be considered in neuropsychological interventions.

Abstract
INTRODUCTION Episodic memory disruptions in epilepsy stem from shared neurocircuitry. While prior research has focused on retrospective memory (RM), prospective memory (PM; i.e. remembering to remember) also deserves consideration given its critical role in the management of daily activities. The current investigation assessed whether PM is associated with disability and quality of life in people with epilepsy. METHODS This cross-sectional, correlational study included a consecutive series of 50 people with epilepsy presenting for neuropsychological evaluation who completed the Royal Prince Alfred Prospective Memory Test (RPA) and Prospective and Retrospective Memory Questionnaire (PRMQ) and 63 demographically comparable healthy adults. The participants with epilepsy also completed clinical measures of neuropsychological ability and questionnaires assessing disability and quality of life. RESULTS People with epilepsy had significantly more frequent memory symptoms as compared to healthy adults at a very large effect size. Worse mood was associated with lower PM ability at a medium effect size and more frequent PM symptoms at a large effect size. A hierarchical linear regression indicated that PM explained 52% of the variance in disability and 43% of the variance in quality of life after accounting for RM ability. CONCLUSIONS PM is associated with poorer everyday functioning among people with epilepsy and shows evidence of incremental value beyond RM ability in that regard. Future studies are needed to understand the complex pathways from PM to functional limitations to inform clinical intervention.

Abstract
Subjective memory evaluation is important for assessing memory abilities and complaints alongside objective measures. In research and clinical settings, questionnaires are used to examine perceived memory ability, memory complaints, and memory beliefs/knowledge. Although they provide a structured measure of self-reported memory, there is some debate as to whether subjective evaluation accurately reflects memory abilities. Specifically, the disconnect between subjective and objective memory measures remains a long-standing issue within the field. Thus, it is essential to evaluate the benefits and limitations of questionnaires that are currently in use. This review encompasses three categories of metamemory questionnaires: self-efficacy, complaints, and multidimensional questionnaires. Factors influencing self-evaluation of memory including knowledge and beliefs about memory, ability to evaluate memory, recent metamemory experiences, and affect are examined. The relationship between subjective and objective memory measures is explored, and considerations for future development and use of metamemory questionnaires are provided.

Abstract
OBJECTIVE Statistical learning, the fundamental cognitive ability of humans to extract regularities across experiences over time, engages the medial temporal lobe (MTL) in the healthy brain. This leads to the hypothesis that statistical learning (SL) may be impaired in patients with epilepsy (PWE) involving the temporal lobe, and that this impairment could contribute to their varied memory deficits. In turn, studies done in collaboration with PWE, that evaluate the necessity of MTL circuitry through disease and causal perturbations, provide an opportunity to advance basic understanding of SL. METHODS We implemented behavioral testing, volumetric analysis of the MTL substructures, and direct electrical brain stimulation to examine SL across a cohort of 61 PWE and 28 healthy controls. RESULTS We found that behavioral performance in an SL task was negatively associated with seizure frequency irrespective of seizure origin. The volume of hippocampal subfields CA1 and CA2/3 correlated with SL performance, suggesting a more specific role of the hippocampus. Transient direct electrical stimulation of the hippocampus disrupted SL. Furthermore, the relationship between SL and seizure frequency was selective, as behavioral performance in an episodic memory task was not impacted by seizure frequency. SIGNIFICANCE Overall, these results suggest that SL may be hippocampally dependent and that the SL task could serve as a clinically useful behavioral assay of seizure frequency that may complement existing approaches such as seizure diaries. Simple and short SL tasks may thus provide patient-centered endpoints for evaluating the efficacy of novel treatments in epilepsy.

Abstract
People with epilepsy frequently express concern about the burden of memory problems in their everyday lives. Self-report memory questionnaires may provide valuable insight into individuals' perceptions of their everyday memory performance and changes over time. Yet, despite their potential utility, the measurement properties of self-report memory questionnaires have not been evaluated in epilepsy. This systematic review aimed to provide a critical appraisal of the measurement properties of self-report memory questionnaires for adults with epilepsy. Following protocol registration (PROSPERO CRD42020210967), a systematic search of PubMed, EMBASE, Web of Science, CINAHL, and PsychInfo from database inception until 27 May 2021 was conducted. Eligible studies were published in English-language peer-reviewed journals, recruited adults with epilepsy, and reported on the development or evaluation of the measurement properties of a self-report memory questionnaire. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology was used to evaluate each study of a measurement property, and results were qualitatively synthesised. In total, 80 articles and one test manual were located containing 153 studies of measurement properties pertinent to 23 self-report memory questionnaires. Overall, no scale could be recommended outright for the evaluation of subjective memory symptoms in adults with epilepsy. This was due to the near absence of dedicated content validation studies relevant to this population and shortcomings in the methodology and scientific reporting of available studies of structural validity. Recommendations to support the advancement and psychometric validation of self-report memory questionnaires for people with epilepsy are provided.

Epilepsy Behav 2024; 150:109554. [PMID: 38041998 DOI: 10.1016/j.yebeh.2023.109554] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 11/03/2023] [Accepted: 11/17/2023] [Indexed: 12/04/2023]
Abstract
OBJECTIVES People with epilepsy (PWE) not only suffer from seizures but also from various psycho-social issues containing facets such as social functioning, anxiety, depression or stigmatization, and consequently quality of life. (1) Assessing reliable change of these issues is crucial to evaluate their course and potential treatment effects. As most psycho-social self-report questionnaires have been validated in separate samples, their clinical-socio-demographic differences may limit the comparability and generalizability of the scales' internal consistency, which is important for the reliable change index (RCI). Using a co-normalized approach, we provide the internal consistency and RCIs for a large set of questionnaires targeting quality of life (QOLIE-31-P), depressive symptoms (NDDI-E), anxiety (GAD-7), seizure severity (LSSS), subjective antiseizure medication adverse events (LAEP), stigma, epilepsy-related fear, and restrictions in daily life (PESOS), and subjective cognition (FLei). As for some German versions of these measures, psychometric data is still missing, we also add important information for the German language area. (2) In addition, knowledge about intercorrelations of these constructs is needed to shape questionnaire usage and treatment approaches. We thus investigate associations of these scales and compare weighted and unweighted subscales of the QOLIE-31-P. METHODS In our prospective study, 202 adult in-patients of the Epilepsy-Center Berlin-Brandenburg with a reliable diagnosis of epilepsy filled out a set of self-report questionnaires between 03/2018 and 03/2021. We calculated Cronbach's α, RCIs, and bivariate intercorrelations and compared the respective correlations of weighted and unweighted scales of the QOLIE-31-P. RESULTS For most of the scales, good to excellent internal consistency was identified. Furthermore, we found intercorrelations in the expected directions with strong links between scales assessing similar constructs (e.g., QOLIE-31-P Cognition and FLei), but weak relationships between measures for different constructs (e.g., QOLIE-31-P Seizure worry and FLei). The QOLIE-31-P Total score was highly correlated with most of the other scales. Some differences regarding their correlational patterns for weighted and unweighted QOLIE-31-P scales were identified. CONCLUSIONS Psycho-social constructs share a large amount of common variance, but still can be separated from each other. The QOLIE-31-P Total score represents an adequate measure of general psycho-social burden.

Influence of psychological factors on the relationship between subjective and objective memory in adults with pharmacoresistant temporal lobe epilepsy. Epilepsy Behav 2024; 150:109552.

Abstract
PURPOSE Many adults with temporal lobe epilepsy (TLE) report subjective cognitive impairment; however, prior studies have shown a discrepancy between these subjective complaints and objective cognitive deficits on neuropsychological measures. Mood disorders/symptoms are also common in TLE and have been linked to greater subjective cognitive difficulties. To further understand these relationships, this retrospective study sought to determine if symptoms of depression and anxiety moderate or mediate the relationship between subjective cognitive impairment and objective cognitive performance in adults with TLE. METHOD Participants were 345 adults (mean age = 40.7; 55 % female) with pharmacoresistant TLE who completed self-report screening measures of depression, anxiety, and subjective cognitive function along with objective memory measures as part of a pre-surgical clinical neuropsychological evaluation. A series of linear regression analyses was conducted to examine the potential moderating and mediating effects of mood on the relationship between subjective and objective memory function after adjusting for relevant covariates. RESULTS Consistent with existing literature, self-reported depression and anxiety symptoms were significantly correlated with subjective memory difficulties across all scales (all p < .001). Subjective memory impairment was also significantly correlated with objective memory performance on neuropsychological measures, albeit with small effect sizes (estimate range 0.04-0.20). Contrary to our hypothesis, depression and anxiety did not moderate or mediate the relationship between subjective memory complaints and objective memory performance. CONCLUSIONS While symptoms of depression and anxiety were associated with subjective memory ability in this cohort of adults with TLE, this study suggests that mood symptoms do not fully explain the relationship between subjective and objective memory function, likely reflecting the complex and multifactorial relationships among these variables. Nevertheless, our results highlight the importance of screening for depression and anxiety symptoms and assessing patients' subjective memory complaints as part of a neuropsychological evaluation as each of these factors tap into a different aspect of the patient functioning.

Abstract
OBJECTIVE Anxiety and depression are common comorbidities in people living with epilepsy. Emerging research suggests that these conditions may even predate epilepsy onset. This review aimed to summarize the prevalence of clinically significant anxiety and depressive symptoms in people with first seizures and newly diagnosed epilepsy, as well as clinicodemographic factors associated with these symptoms. METHODS A scoping literature review was performed. OVID Medline and Embase were searched from January 1, 2000, through May 1, 2022. Articles of interest were selected based on predetermined inclusion and exclusion criteria. RESULTS From 1836 studies identified on screening, 16 met eligibility criteria and were included in the review. Clinically significant anxiety and depressive symptoms, as determined by validated cutoff scores for anxiety and depression screening instruments, were common in people with first seizures (range 13-28%) and newly diagnosed epilepsy (range 11-45%). They were associated with a range of clinicodemographic factors including past psychiatric history and trauma, personality traits, self-esteem, and stigma profiles. SIGNIFICANCE There is substantial evidence that clinically significant anxiety and depressive symptoms are often present at the time and shortly following the first seizure or epilepsy diagnosis. Future research is needed to better understand the complex interactions between these common psychiatric comorbidities, new-onset seizure disorders, and certain clinicodemographic characteristics. This knowledge may inform targeted and holistic treatment approaches.

Abstract
Introduction Prospective memory (PM) is the ability to remember future intentions, and PM function is closely related to independence in daily life, particularly in patients with temporal lobe epilepsy (TLE). As PM involves various cognitive components of attention, working memory, inhibition and other executive functions, this study investigated how TLE may affect PM components and the underlying neural mechanisms. Methods Sixty-four subjects were recruited, including 20 refractory TLE patients, 18 well-controlled TLE patients and 26 age-matched healthy controls. A set of neuropsychological tests was administered to assess specific brain functions. An event-related potential (ERP) task was used to further explore how PM and its components would be differentially affected in the two TLE types. Results Our findings revealed that: (1) refractory TLE patients scored lower than the healthy controls in the digit span, Verbal Fluency Test and Symbol Digit Modalities Test; (2) refractory TLE patients exhibited impaired PM performance and reduced prospective positivity amplitudes over the frontal, central and parietal regions in ERP experiments when compared to the healthy controls; and (3) decreased P3 amplitudes in the nogo trials were observed over the frontal-central sites in refractory but not in well-controlled TLE patients. Discussion To our knowledge, this is the first ERP study on PM that has specifically identified PM impairment in refractory but not in well-controlled TLE patients. Our finding of double dissociation in PM components suggests that inhibition dysfunction may be the main reason for PM deficit in refractory TLE patients. The present results have clinical implications for neuropsychological rehabilitation in TLE patients.

Abstract
While memory and language functional magnetic resonance imaging (fMRI) paradigms are becoming evermore refined, the measures of outcome they predict following epilepsy surgery tend to remain single scores on pencil and paper tests that were developed decades ago and have been repeatedly shown to bear little relation to patients' subjective reports of memory problems in the real world. The growing imbalance between the increasing sophistication of the predictive paradigms on the one hand and the vintage measures of the outcome on the other in the fMRI epilepsy surgery literature threatens the clinical relevance of studies employing these technologies. This paper examines some of the core principles of assessing neuropsychological outcomes following epilepsy surgery and explores how these may be adapted and applied in fMRI study designs to maximize the clinical relevance of these studies.

Abstract
Cognitive complaints are very common in people diagnosed with epilepsy. These difficulties are often another manifestation of the same pathology responsible for seizures. They can be further exacerbated by treatments aimed at seizure control. Other common comorbidities of epilepsy such as low mood and elevated anxiety can also contribute to cognitive complaints. There is surprisingly little overlap between memory complaints and performance on formal memory tests in this population. This article examines the multifactorial and heterogeneous nature of cognitive difficulties in epilepsy and makes the case for the provision of basic psychoeducation as the foundation for all interventions aimed at ameliorating these difficulties in this patient population.

Abstract
OBJECTIVE Studies have observed variable associations of prior contact sport participation with subjective and objective measures of cognitive function. This study directly investigated the association between subjective self-report and objective performance-based cognition among former collegiate football players, as well as its relationship to self-reported concussion history. METHODS Former collegiate football players (N = 57; mean age = 37.9 years [SD = 1.49]) retired from sport 15-years prior were enrolled. Linear regression models examined associations between subjective cognition (Quality of Life in Neurological Disorders Cognitive Functioning-Short Form), and performance on a neuropsychological battery. Domain specific (executive function) metrics of subjective (Behavior Rating Inventory of Executive Function-Adult) and objective cognition were also exclusively examined. Associations between self-reported concussion history with subjective and objective measures were tested. Potential influential factors (sleep quality and distress) were included as covariates. RESULTS Subjective cognition was not significantly associated with any objective measures of cognitive functioning (p's > .05). Greater self-reported concussion history was inversely associated with subjective cognition (B = -2.49, p = .004), but not objective performance-based cognition (p's > .05). Distress was significantly related to all metrics of subjective cognition (p's < .001) as well as performance on delayed recall and verbal fluency (p's < .05). Sleep quality was only significantly related to timed visuospatial sequencing (p = .033). CONCLUSIONS Reliance on self-reported measures of cognitive functioning alone is insufficient when assessing cognition in former contact sport athletes. Assessment of other factors known to influence subjective cognitive complaints should also be examined in determining the presence of cognitive deficits.

Abstract
Clinical neuropsychology has been a valuable asset to neurologic surgery, contributing to lateralization and localization of pathologic brain tissue, identification of eloquent cortex, and evaluation of postoperative neuropsychological functioning. Moreover, neuropsychologists provide empirically driven interventions aimed at supporting preparation and/or recovery of neurosurgery patients. Nonetheless, several challenges may limit the reliability, validity, and generalizability of the assessment data obtained and reduce the usefulness of other neuropsychological services provided. Specifically, linguistic, cultural, educational, and other biases associated with demographic characteristics can lead to a narrowed view of an individual's life experiences, which must be confronted to fulfill the mission of ensuring that all patients have access to care that is appropriate to their needs. Instead of perceiving these challenges as insurmountable barriers, such issues can be viewed as opportunities to catalyze change and foster innovation for the future of neuropsychological care in neurosurgical settings. In addition to reviewing the possible mechanisms of these obstacles, the current article offers tangible solutions at both a macro level (e.g., discipline-wide transformations) and micro level (e.g., individualized patient-centric approaches). Outlined are practical techniques to potentially improve consensus and standardization of methods, advance and globalize research, expand representativeness of measures and practices to serve diverse individuals, and increase treatment adherence through engagement of patients and their families.

Abstract
Complaints pertaining to memory functioning are among the most often reported cognitive symptoms in patients with epilepsy. However, research suggests a considerable mismatch between patients' perception of memory functioning and the objective performance as measured with standardized neuropsychological tests. Depressive mood might be an important factor in explaining this discrepancy, though other variables have also occasionally been reported as relevant. There are mixed results as to which role these factors play in determining the overall quality of life of patients with epilepsy. The present study aimed to quantify the mismatch between subjective and objective memory functioning by taking into account the dynamic change of these factors as well as depressive symptoms after epilepsy surgery. Moreover, the influencing factors of subjective and objective memory change were investigated as well as their effects on the overall quality of life. Pre- and postoperative data from 78 patients with focal epilepsy were retrospectively analyzed. The results showed that (1) patients with clinically relevant postoperative depressive symptoms underestimate their actual memory performance; (2) for non-seizure-free patients, a postoperative decrease in depressive symptoms was associated with a tendency to underestimate memory decline; (3) the relationship between objective memory change and quality of life is mediated by the factors subjective memory change and depressive mood. Our data demonstrate a quantitative approximation of a pronounced depression-related negative biased self-perception of memory functioning of roughly 1 to 1.5 standard deviations. Moreover, it seems that when patients are relieved of having recurrent epileptic seizures, they may be less influenced by depressive symptoms when judging their memory change. Taken together, our study demonstrates the clinical relevance of incorporating subjective measures of memory functioning and mood that go beyond objective memory performance for the interpretation of how changes in memory functioning may affect patients' quality of life after epilepsy surgery.

Abstract
Memory deficits are commonly associated with temporal-lobe epilepsy. Memory may worsen after surgical resection of the temporal lobe. Risk factors for decline are structural integrity of the mesial temporal lobe structures and intact pre-operative memory. Subjective memory complaints are influenced by depression or other psychological disorders. A 16-year-old girl underwent resection from the right lateral and medial temporal lobe and after surgery she complained of a significant memory impairment, which was unexpected given her baseline assessment. Before undertaking a neuropsychological assessment, she was referred for a psychiatric consultation which revealed depression, leading to treatment with anditdepressant medication. Over time she also admitted to severe headaches and inadequate sleep. With these issues addressed, assessment indicated memory performance had not changed relative to her preoperative baseline with stability or improvement in memory across longitudinal assessments. This case illustrates the contribution of mood state and other potential factors in contributing to subjective memory complaints.

Abstract
OBJECTIVES Memory complaints in patients with epilepsy have been well-studied. Although memory complaints are commonly reported by patients with chronic epilepsy, to date, few studies exist on memory complaints at the onset of epilepsy. The present study investigated the presence of memory complaints and their relation to mood and memory performance in patients after their first seizure. Thereby, we examined differences between individuals who received a diagnosis of epilepsy immediately with the occurrence of their first seizure and those who were diagnosed as having the first epileptic seizure, without fulfilling the ILAE criteria for the diagnosis of epilepsy. METHODS Sixty-one patients participated in the study and completed, among others, a memory task and questionnaires on memory complaints and depression after their first epileptic seizure. We investigated the level of memory complaints and their correlation and accuracy in classification with a memory measure. We compared patients who received an epilepsy diagnosis after the first seizure with those who did not. RESULTS Memory complaints did not correlate with objective memory performance. Classification into impaired/unimpaired showed low concordance between memory complaints and neuropsychological memory measures. After their first epileptic seizure, patients reported few memory complaints overall (10%), and there were no differences in memory complaints between patients with and without an epilepsy diagnosis. CONCLUSION At epilepsy onset, in contrast to established epilepsies, memory complaints are rare. Although influences of anticonvulsant drugs and seizures are not present at the beginning of epilepsy, this substantial absence of memory complaints at epilepsy onset emphasizes the need for comprehensive neurological and psychological treatment early with the given diagnosis. Treatment should focus on anticonvulsant drug regimens, patients' concerns and convey realistic expectations.

Abstract
RATIONALE Cognitive problems are common in adults with epilepsy and significantly affect their quality of life. HOBSCOTCH (HOme Based Self-management and COgnitive Training CHanges lives) was developed to teach problem-solving and compensatory memory strategies to these individuals. This study examined whether HOBSCOTCH is associated with improvement in specific aspects of subjective executive functions. METHODS Fifty-one adults, age 18-65, with epilepsy and subjective cognitive concerns were randomized to receive HOBSCOTCH (n = 31) or a care-as-usual control sample (n = 20). Participants completed the Behavior Rating Inventory of Executive Function-Adult version (BRIEF-A), as well as the Patient Health Questionnaire-9 (PHQ-9) to assess depression. Rates of elevated (i.e., T ≥ 65, impaired) BRIEF-A scores at baseline, as well as pre-post score changes for the BRIEF-A clinical scales were evaluated. Significance was set at α = 0.05, one-tailed, given our directional hypothesis. RESULTS At baseline, a considerable percentage of patients in the overall sample endorsed executive dysfunction on BRIEF-A scales: Inhibit = 28%, Shift = 51%, Emotional Control = 45%, Self-Monitor = 33%, Initiate = 35%, Working Memory = 88%, Plan/Organize = 45%, Task Monitor = 47%, Organization of Materials = 28%. Significant improvement was seen in mean T-scores for Inhibit, Shift, Initiate, and Working Memory in the treatment group, but only Working Memory improved in the control group. The control group endorsed worse task monitoring and organization of materials at baseline and follow-up. Change in depression was not observed for either group, and there was no association between changes in depression and BRIEF-A scores. CONCLUSIONS A sizeable subset of adults with epilepsy reported experiencing executive dysfunction in their everyday lives, especially for working memory. HOBSCOTCH resulted in amelioration of subjective executive functioning independent of changes in mood.

Clinical predictors of discordance between screening tests and psychiatric assessment for depressive and anxiety disorders among patients being evaluated for seizure disorders. Epilepsia 2021; 62:1170-1183.

Abstract
OBJECTIVE This study was undertaken to identify factors that predict discordance between the screening instruments Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) and Generalized Anxiety Disorder scale (GAD-7), and diagnoses made by qualified psychiatrists among patients with seizure disorders. Importantly, this is not a validation study; rather, it investigates clinicodemographic predictors of discordance between screening tests and psychiatric assessment. METHODS Adult patients admitted for inpatient video-electroencephalographic monitoring completed eight psychometric instruments, including the NDDI-E and GAD-7, and psychiatric assessment. Patients were grouped according to agreement between the screening instrument and psychiatrists' diagnoses. Screening was "discordant" if the outcome differed from the psychiatrist's diagnosis, including both false positive and false negative results. Bayesian statistical analyses were used to identify factors associated with discordance. RESULTS A total of 411 patients met inclusion criteria; mean age was 39.6 years, and 55.5% (n = 228) were female. Depression screening was discordant in 33% of cases (n = 136/411), driven by false positives (n = 76/136, 56%) rather than false negatives (n = 60/136, 44%). Likewise, anxiety screening was discordant in one third of cases (n = 121/411, 29%) due to false positives (n = 60/121, 50%) and false negatives (n = 61/121, 50%). Seven clinical factors were predictive of discordant screening for both depression and anxiety: greater dissociative symptoms, greater patient-reported adverse events, subjective cognitive impairment, negative affect, detachment, disinhibition, and psychoticism. When the analyses were restricted to only patients with psychogenic nonepileptic seizures (PNES) or epilepsy, the rate of discordant depression screening was higher in the PNES group (n = 29, 47%) compared to the epilepsy group (n = 70, 30%, Bayes factor for the alternative hypothesis = 4.65). SIGNIFICANCE Patients with seizure disorders who self-report a variety of psychiatric and other symptoms should be evaluated more thoroughly for depression and anxiety, regardless of screening test results, especially if they have PNES and not epilepsy. Clinical assessment by a qualified psychiatrist remains essential in diagnosing depressive and anxiety disorders among such patients.

Abstract
INTRODUCTION Self-awareness of cognitive, emotional, functional, and social performance is critical for compliance with treatment. However, few studies have investigated self-awareness and the associated effects on other cognitive variables in patients with temporal lobe epilepsy (TLE) after surgical treatment. AIM This study was designed to investigate the prevalence of impaired self-awareness (ISA) in patients with TLE who have undergone surgical treatment. Associated correlations with clinical variables (frequency of seizures before surgery, time elapsed since the epilepsy diagnosis, depression, and anxiety) and verbal and visual episodic memory function and differences between patients with right and left TLE were also investigated. METHOD Twenty-three adults with TLE after surgical treatment were assessed with the Patient Competency Rating Scale (PCRS-R-BR), the Rey Auditory Verbal Learning Task (RAVLT), and the Modified Ruche Visuospatial Learning Test (RUCHE-M). Patients were considered to have memory dysfunction if delayed recall as assessed with the RUCHE-M or RAVLT was at or below the 25th percentile. Patients were considered to have ISA if PCRS-R-BR discrepancy scores were at or above the 75th percentile. Underestimated cognitive ability (UCA) was defined as a PCRS-R-BR discrepancy percentile score ≤25. Results were analyzed using frequency, Spearman correlation, regression analyses, and the Mann-Whitney test. RESULTS Frequency analysis of the total sample indicated ISA in 39.13% of patients (n = 9), UCA in 39.13% of patients (n = 9), and impaired verbal and/or visual memory performance in 69.56% of patients (n = 16). Moderate positive correlations were found between the frequency of seizures before surgical treatment and relatives' reports, as well as between the duration of time that had elapsed since the epilepsy diagnosis and patient reports. Negative and moderate correlations were found between the frequency of seizures and the discrepancy score, as well as between depression and patient reports. No differences in PCRS-R-BR were found between patients with right vs. left TLE. No clinical variables significantly predicted self-report or self-awareness. CONCLUSION Patients with TLE exhibit various patterns of ISA and negative effects on cognitive function after surgical treatment. Emotional factors and relatives' reports must be considered when assessing these patients.

Abstract
OBJECTIVE The aim of this study was to conduct item reduction of the Memory Assessment Clinics Self-Rating Scale (MAC-S) to create a briefer measure that can be used to quickly evaluate subjective memory complaints in patients with epilepsy. Method: A total of 1333 adults with focal epilepsy completed the original 49-item MAC-S. The sample was randomly split into three subsamples, and a series of analyses (i.e. exploratory factor analysis, confirmatory factor analysis, and item response theory analyses) was conducted to identify an alternative factor structure, with a reduced number of items. A panel of 5 neuropsychologists independently reviewed the final model to assess appropriateness of each individual item as well as the factor loadings and overall factor structure. Final factor titles were subsequently decided as a group. Results: Five factors were identified: Attention, Working Memory, Retrieval, Semantic Memory, and Episodic Memory. The length of the MAC-S was reduced from 49 to 30 items, with items being removed because they failed to load onto any of the factors substantially, or because of poor item discrimination or threshold levels. Conclusions: The Memory Assessment Clinics Scale for Epilepsy (MAC-E), is an updated, brief measure of subjective memory functioning that can be used to efficiently assess relevant, every-day memory abilities in patients with epilepsy within both clinical and research settings.

Seizure 2020; 83:89-97. [PMID: 33120327 PMCID: PMC7561524 DOI: 10.1016/j.seizure.2020.10.005] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 09/30/2020] [Accepted: 10/10/2020] [Indexed: 01/17/2023] Open
Abstract
PURPOSE Traditional neuropsychological testing carries elevated COVID-19 risk for both examinee and examiner. Here we describe how the pilot study of the Australian Epilepsy Project (AEP) has transitioned to tele-neuropsychology (teleNP), enabling continued safe operations during the pandemic. METHODS The AEP includes adults (age 18-60) with a first unprovoked seizure, new diagnosis of epilepsy or drug resistant focal epilepsy. Shortly after launching the study, COVID-related restrictions necessitated adaptation to teleNP, including delivery of verbal tasks via videoconference; visual stimulus delivery via document camera; use of web-hosted, computerised assessment; substitution of oral versions for written tests; online delivery of questionnaires; and discontinuation of telehealth incompatible tasks. RESULTS To date, we have completed 24 teleNP assessments: 18 remotely (participant in own home) and six on-site (participant using equipment at research facility). Five face-to-face assessments were conducted prior to the transition to teleNP. Eight of 408 tests administered via teleNP (1.9 %) have been invalidated, for a variety of reasons (technical, procedural, environmental). Data confirm typical patterns of epilepsy-related deficits (p < .05) affecting processing speed, executive function, language and memory. Questionnaire responses indicate elevated rates of patients at high risk of mood (34 %) and anxiety disorder (38 %). CONCLUSION Research teleNP assessments reveal a typical pattern of impairments in epilepsy. A range of issues must be considered when introducing teleNP, such as technical and administrative set up, test selection and delivery, and cohort suitability. TeleNP enables large-scale neuropsychological research during periods of social distancing (and beyond), and offers an opportunity to expand the reach and breadth of neuropsychological services.

Abstract
While cognition and depression have often been studied in patients with epilepsy, only a few studies have so far attempted to link these two domains, and more specifically to investigate the specific impact of depression on cognition in epilepsy. In this review, we performed an extensive search of the literature database to provide a better understanding of this subject. Using several inclusion criteria (adult population, quantitative depression/neuropsychological assessment, statistical analyses of the impact of depression on cognitive scores, patients with epilepsy (PWE) and no other neurological disease, and studies including at least 20 patients), we identified 20 articles (out of 712 search results) that investigated both depression and cognition in PWE. Their results were summarized using a narrative and descriptive approach. This review highlights a variable impact of depression on cognition in PWE, depending on the laterality of the seizure onset zone, the type of epilepsy and the surgical context. We emphasize the need for a systematic depression assessment in these patients, especially since depressed PWE will benefit from prompt and appropriate care to help them avoid cognitive decline, particularly in a surgical context.

Epilepsy Behav 2020; 104:106920.

Abstract
Accelerated long-term forgetting (ALF) is a recently discovered memory disorder characterized by intact acquisition and retention over short delays, followed by abnormally fast rates of forgetting. Accelerated long-term forgetting has been repeatedly found in children, but not in adults, with genetic generalized epilepsy (GGE). It is possible that this discrepancy is due to a difference in paradigms used in these studies. The current study aimed to determine whether adults with GGE displayed ALF using two paradigms, one that required complete learning and another one that did not. In addition, we explored the relationships with everyday memory difficulties, working memory, mood, and epilepsy variables. Fourteen adults with GGE were compared with 16 healthy controls on two verbal memory tests: a modified version of the California Verbal Learning Test learned to a criterion of 100% (complete learning) and Logical Memory from the Wechsler Memory Scale (Fourth Edition) presented only once (incomplete learning). Recall was tested at 2 min, 30 min, and 1 week, and recognition at 1 week only. Working memory, everyday memory, and mood were also assessed. We found no evidence of ALF on either of the two verbal memory paradigms on recall or recognition tests although patients displayed significantly poorer working memory. Moreover, patients with GGE reported significantly more memory difficulties in everyday life, and these were associated with greater mood disturbances but not with memory tests scores. Greater number of antiepileptic drugs and epilepsy severity also related to memory scores on some tests. Our study suggests that a difference in paradigms used to investigate ALF in children and adults with GGE is unlikely to explain the differences in findings. The study tentatively raises a hypothesis that developmental factors may play a role in ALF in patients with GGE; children with GGE may grow out of ALF. Nevertheless, this hypothesis would need to be tested in a longitudinal study that would follow patients from childhood to early adulthood.

Is the computerized assessment of psychomotor speed more sensitive to cognitive effects of antiepileptic pharmacotherapy than tests with a focus on higher-order cognitive processing? Implications for the choice of sensitive test parameters. Eur Neuropsychopharmacol 2019; 29:1273-1281. [PMID: 31606304 DOI: 10.1016/j.euroneuro.2019.09.010] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2019] [Revised: 07/09/2019] [Accepted: 09/19/2019] [Indexed: 02/04/2023]
Abstract
The study evaluated whether it is psychomotor speed or higher-order cognitive processing which is primarily affected by antiepileptic drug (AED) treatment in epilepsy and whether computerized testing versus paper-pencil testing of executive functions is more sensitive. In this retrospective observational study, 55 patients with epilepsy underwent NeuroCog FXⓇ, a computerized battery assessing "psychomotor speed/alertness" and "cognitive processing" via 8 tasks, and EpiTrackⓇ, a paper-pencil screening of "executive functions and working memory" based on 6 subtests. Test performance was related to the number of drugs and the Defined Daily Dose and the presence/absence of AEDs with known adverse psychotropic effects. EpiTrackⓇ performance correlated with "cognitive processing" of the NeuroCog FXⓇ but not with "psychomotor speed/alertness". Significant correlations with drug load were mainly yielded for EpiTrackⓇ (number of AEDs: r = -0.551, total DDD: r = -0.452) and "cognitive processing" (number of AEDs: r = -0.433, total DDD: r = -0.415). "Psychomotor speed/alertness" was less related to drug load (number of AEDs: r = -0.285, total DDD: r = -0.232). Statistical control for "psychomotor speed/alertness" hardly changed the correlations of EpiTrackⓇ or "cognitive processing" with drug load indices. AEDs with known adverse profiles negatively affected EpiTrackⓇ and the "cognitive processing" but not the "psychomotor speed/alertness" domain of the computerized test. The results demonstrate that it is less basal psychomotor speed than higher-order cognitive processing which is negatively affected by antiepileptic pharmacotherapy. The results question the value of (computer-)tests with a major emphasis on psychomotor speed and alertness for cognitive drug monitoring.

Abstract
OBJECTIVE This retrospective, observational study investigated the relationship between objective naming decline and patient report of subjective decline in language functioning following epilepsy surgery. The role of depression in this relationship was also examined. METHODS A total of 429 adults with pharmacoresistant epilepsy completed the Boston Naming Test (BNT) and Memory Assessment Clinics Self-Rating Scale (MAC-S) before and after resective surgery. Multiple regression analyses were used to examine the relationship between objective naming decline and subjective language functioning, while controlling for the confounding effect of depression. RESULTS Individuals who experienced moderate to severe naming decline (≥11 raw points on BNT) following surgery reported a decline in subjective language functioning (p < .001) and endorsed problems with word-retrieval as well as more general semantic abilities. Those who experienced mild naming decline (5-10 raw points) also reported an increase in subjective language problems (p = .006). Complaints in this group were less severe than in those with more marked naming declines and were primarily related to word-retrieval. Both of these relationships remained significant after controlling for the confounding effect of depression (p < .005-.014). CONCLUSIONS Individuals with epilepsy who experience naming decline following surgery perceive these declines in their daily life, regardless of whether or not they are depressed. Findings support the utilization of risk models to predict naming outcome and the importance of counseling patients regarding the risk for naming decline following surgery.

Abstract
INTRODUCTION Many patients with brain cancer experience cognitive problems. In this narrative review, we comprehensively evaluated empirical studies on various intervention approaches for cognitive problems in these patients. METHODS Intervention studies that reported effects on cognitive functioning (either objectively tested or subjectively reported) in adult patients with primary and/or secondary brain tumours were identified through online searches in PubMed (MEDLINE) and Web of Science up to 13 March 2019. RESULTS Of the 364 identified records, 10 pharmacological (including five randomised placebo-controlled trials), 10 cognitive rehabilitation (including five [pilot] RCTs) and two multiple-group exercise studies matched the inclusion criteria. Seventeen of 22 studies had final sample sizes smaller than 40. Several cognitive rehabilitation studies and some pharmacological approaches (donepezil and memantine) showed (at least partial) benefits for cognitive problems in adults with brain cancer. The effects of other pharmacological and exercise interventions were inconclusive and/or preliminary. CONCLUSION Overall, drawing firm conclusions is complicated due to various methodological shortcomings, including the absence of a (placebo) control group and small sample sizes. Promising effects have been reported for cognitive rehabilitation and some pharmacological approaches. Suggestions for more thorough research with respect to the various approaches are provided.

Abstract
OBJECTIVE This study examined cognitive function in patients with epilepsy using the AD8 screening questionnaire to assess the frequency of, and factors associated with, cognitive impairment in these patients. METHOD The AD8 screening questionnaire for cognitive impairment was administered to one hundred consecutive patients diagnosed with epilepsy who attended a dedicated epilepsy clinic based in a tertiary care neuroscience center. Where possible, accompanying informants also completed AD8 on behalf of the patient. RESULTS Forty-eight percent of patients in this cohort scored above the AD8 cutoff (higher scores are considered worse) for cognitive impairment. Categorizing patient groups by AD8 score showed no difference (null hypothesis not rejected) in patient age, new or follow-up appointment, epilepsy type (partial/generalized), or treatment (monotherapy/polytherapy), but a significant difference (null hypothesis rejected) was found for disee duration, with those scoring above the AD8 cutoff having a significantly longer disease duration. There was no correlation between AD8 scores and patient age but a weak positive correlation with disease duration. AD8 questionnaires completed by informants showed a similar frequency of cognitive impairment (54%), and patient:informant AD8 scores showed substantial agreement beyond chance. CONCLUSIONS AD8 is acceptable to patients with epilepsy and their informants for the assessment of cognitive function. In this dedicated epilepsy clinic, its use suggested a high frequency of cognitive impairment in both self-rating and informant assessments. A less sensitive, more specific cognitive screening instrument (CSI) might be more desirable in this population. Duration of epilepsy or some factor related to it may contribute to cognitive symptoms.

Abstract
UNLABELLED The study examined the role of mood and illness perceptions in explaining the variance in the memory complaints of patients with epilepsy. METHOD Forty-four patients from an outpatient tertiary care center and 43 volunteer controls completed a formal assessment of memory and a verbal fluency test, as well as validated self-report questionnaires on memory complaints, mood, and illness perceptions. RESULTS In hierarchical multiple regression analyses, objective memory test performance and verbal fluency did not contribute significantly to the variance in memory complaints for either patients or controls. In patients, illness perceptions and mood were highly correlated. Illness perceptions correlated more highly with memory complaints than mood and were therefore added to the multiple regression analysis. This accounted for an additional 25% of the variance, after controlling for objective memory test performance and verbal fluency, and the model was significant (model B). In order to compare with other studies, mood was added to a second model, instead of illness perceptions. This accounted for an additional 24% of the variance, which was again significant (model C). In controls, low mood accounted for 11% of the variance in memory complaints (model C2). SUMMARY A measure of illness perceptions was more highly correlated with the memory complaints of patients with epilepsy than with a measure of mood. In a hierarchical multiple regression model, illness perceptions accounted for 25% of the variance in memory complaints. Illness perceptions could provide useful information in a clinical investigation into the self-reported memory complaints of patients with epilepsy, alongside the assessment of mood and formal memory testing.

Abstract
Previous research has pointed to a deficit in associative recognition in temporal lobe epilepsy (TLE). Associative recognition tasks require discrimination between various combinations of words which have and have not been seen previously (such as old-old or old-new pairs). People with TLE tend to respond to rearranged old-old pairs as if they are “intact” old-old pairs, which has been interpreted as a failure to use a recollection strategy to overcome the familiarity of two recombined words into a new pairing. We examined this specific deficit in the context of metacognition, using postdecision confidence judgements at test. We expected that TLE patients would show inappropriate levels of confidence for associative recognition. Although TLE patients reported lower confidence levels in their responses overall, they were sensitive to the difficulty of varying pair types in their judgements and gave significantly higher confidence ratings for their correct answers. We conclude that a strategic deficit is not at play in the associative recognition of people with TLE, insofar as they are able to monitor the status of their memory system. This adds to a growing body of research suggesting that recollection is impaired in TLE, but not metacognition.

Abstract
PURPOSE The purpose of this study was to test the mediating effect of psychological distress in the relationship between chemotherapy related cognitive impairment (CRCI) and quality of life (QOL) in people with cancer. METHODS A purposive sample of 130 patients undergoing chemotherapy was recruited for the cross-sectional survey design. Data were collected from November 2014 to June 2015. The instruments were K-MMSE (Korean Mini-Mental State Examination), Everyday Cognition (ECog), Hospital Anxiety Depression Scale (HADS), and Functional Assessment of Cancer Therapy-General (FACT-G). Data were analyzed using descriptive statistics, correlation, and multiple regression using Baron and Kenny steps for mediation. RESULTS The mean score for objective cognitive function was 27.95 and 69.32 for perceived cognitive decline. Overall quality of life was 91.74. The mean score was 17.52 for psychological distress. The prevalence was 56.2% for anxiety and 63.1% for depression, and 20.0% for CRCI. There were significant correlations among the variables, objective cognitive function and self-reported cognitive decline, psychological distress, and quality of life. Psychological distress was directly affected by CRCI. (R²=29%). QOL was directly affected by CRCI. Psychological distress and CRCI effected QOL (R²=43%). Psychological distress had a partial mediating effect (β=-.56, p<.001) in the relationship between self-reported cognitive decline and quality of life (Sobel test: Z=-5.08, p<.001). CONCLUSION Based on the findings of this study, nursing intervention programs focusing on managing cognitive decline, and decreasing psychological distress are highly recommended to improve quality of life in cancer patients.

Abstract
AIM This study aimed to assess the relationship between objective measures of cognition and subjective perception of cognitive functioning reported by patients with epilepsy and their caregivers. METHODS One hundred patients with epilepsy attending hospital neurology outpatient clinics and their caregivers were enrolled in this study. The EpiTrack (version 1) brief cognitive screening tool was used to measure objective impairment, the ABNAS questionnaire (A-B Neuropsychological Assessment Schedule) to assess subjective cognitive performance, and a version of the ABNAS designed to be completed by caregivers (C-ABNAS) to document caregivers' views. Patient anxiety and depression were measured using the Hospital Anxiety and Depression Scale (HADS) and considered as covariates. Patients with an uncertain diagnosis of epilepsy or likely severe comorbid mood or anxiety disorders were excluded. RESULTS Data from 82 patients were analyzed after exclusion of patients with uncertain diagnoses or likely severe comorbid mood or anxiety disorders. Fifty-nine (72%) had a degree of objective cognitive impairment. Fifty (84.7%) of these 59 patients had 'high' ABNAS scores concordant with the objective assessment, and 43 (72.9%) had high C-ABNAS scores matching the abnormalities detected by objective screening. Of the 23 (28%) patients without objective cognitive impairment, seven (30.4%) had concordantly low ABNAS scores, and 10 (43.4%) had concordantly low C-ABNAS scores. Patient memory impairment was more often reported by patients themselves than by caregivers (p=0.011). Carers were significantly more likely to rate patients as having impaired motor coordination than patients themselves. A small part of the variance of the EpiTrack score was predicted by the C-ABNAS. Objective cognitive performance did not predict ABNAS or C-ABNAS scores. CONCLUSIONS Self-report or caregiver report questionnaires identify patients with epilepsy and objective cognitive impairment more accurately than patients with intact cognition. Those without objective evidence of cognitive impairment may, nevertheless, perceive themselves as having memory dysfunction; it is these patients, therefore, who most require both subjective and objective assessments of cognition, including carers' assessments, in order to establish the nature of their symptoms. None of these assessment measures can be used as a reliable proxy for another, each contributes individually to a comprehensive assessment of cognition, and all must be used in conjunction with measures of mood and anxiety.

Abstract
Memory complaints are common among older adults with epilepsy (OAE), though discrepancy between subjective complaints and objective performance often exists. This study examined how accurately OAE and their informants reported on the participant's cognitive difficulties by comparing ratings of everyday cognition to objective performance. Thirty-seven OAE and 27 older adult controls completed a brief battery of neuropsychological tests, the Beck Depression Inventory, and the Cognitive Difficulties Scale (CDS). Each participant had an informant who completed the CDS. Older adults with epilepsy performed worse than controls on cognitive testing and reported more subjective cognitive complaints. Neither participant- nor informant-reported cognitive complaints were related to performance on any of the neuropsychological tests for either the group with epilepsy or control group, but both were related to greater depressive symptoms. Results suggest that subjective report of cognitive problems by both OAE and their informants may not reliably reflect the extent to which these problems exist.

Abstract
BACKGROUND Many people with epilepsy report experiencing psychological difficulties such as anxiety, depression and neuropsychological deficits including memory problems. Research has shown that these difficulties are often present not only for people with chronic epilepsy but also for people with newly diagnosed epilepsy. Despite this, there are very few published interventions that detail means to help people with newly diagnosed epilepsy manage these problems. OBJECTIVES To identify and assess possible psychological and neuropsychological interventions for adults with newly diagnosed epilepsy. SEARCH METHODS We searched the following databases on 30 June 2015: the Cochrane Epilepsy Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), SCOPUS, PsycINFO, CINAHL, ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). SELECTION CRITERIA This review includes all randomised controlled trials, quasi-randomised controlled trials, prospective cohort controlled studies, and prospective before and after studies which include psychological or neuropsychological interventions for people with newly diagnosed epilepsy. We excluded studies that included people with epilepsy and any other psychological disorder or neurological condition. We excluded studies carried out which recruited only children. DATA COLLECTION AND ANALYSIS We used the standard methodological procedure expected by The Cochrane Collaboration. Two authors independently completed data extraction and risk of bias analysis. The results of this were cross-checked and third author resolved any discrepancies. In the event of missing data, we contacted the study authors. Meta-analysis was not completed due to differences in the intervention and outcomes reported in the two studies. MAIN RESULTS We included two randomised controlled trials assessing psychological interventions for people with newly diagnosed epilepsy. One study assessed a cognitive behavioural intervention (CBI) in an adolescent population. This study was rated as low quality. One study assessed a specialist nurse intervention in an adult population. This study was rating as very low quality.We rated one study as having unclear risk of bias and one study as having high risk of bias.The CBI study indicated that this intervention could significantly reduce depressive symptoms in people with subthreshold depressive disorder. However, the study assessing the effectiveness of a nurse intervention found no significant benefit for depressive symptoms,but did find that in individuals with the least knowledge of epilepsy, a nurse intervention could increase their knowledge of epilepsy scores. AUTHORS' CONCLUSIONS Meta-analysis was not possible as we identified only two studies and they utilised different interventions and outcome measures.Previous research has highlighted the impact of psychological and neuropsychological difficulties experienced by people with epilepsy and the negative effect this has on their quality of life. The main finding of this review is that there is a paucity of research assessing possible neuropsychological and psychological interventions for adults with newly diagnosed epilepsy.

Abstract
Temporal lobe epilepsy (TLE) is associated with differing degrees of objective and subjective memory impairment. Memory self-report is an important part of the assessment process but few reliable and valid measures have been researched with this group. We thus aimed to explore subjective impairments with a robust measure: the multifactorial memory questionnaire (MMQ; Troyer and Rich, 2002). This was administered to 82 people with TLE and an age and education matched control group of the same size. The questionnaire probes worries about memory (MMQ-contentment); subjective forgetfulness (MMQ-ability); and use of compensatory strategies (MMQ-strategy). The TLE group reported significantly more worries about their memory, more instances of forgetfulness and use of more strategies than control participants. Strategy use was related to demographic factors in controls but not in the TLE group. Analysis of epilepsy related factors indicated that hemispheric laterlisation subgroups did not differ from one another on any subscale, nor did participants grouped according to their use of one, several, or no anti-epileptic medications. Measures of chronicity including age of onset and illness duration also failed to correlate with the MMQ subscales. Because objective memory performance is often impaired in more chronic and intractable cases, the lack of difference in subjective complaint is surprising and warrants future research to examine the relationship between this questionnaire and standardized test scores. We conclude that the MMQ is a clinical measure that could be used either outside or in tandem with neuropsychological assessment to gauge everyday memory difficulties among epilepsy patients.

Abstract
BACKGROUND Studies in cancer and noncancer populations demonstrate lower than expected correlations between subjective cognitive symptoms and cognitive functioning as determined by standardized neuropsychological tests. This paper systematically examines the association between subjective and objective cognitive functioning in patients with low-grade glioma and the associations of these indicators of cognitive function with clusters of sociodemographic, clinical, and self-reported physical and mental health factors. METHODS Multiple regression analyses with the subjective and 2 objective indicators of cognitive functioning as dependent variables and 4 clusters of predictor variables were conducted in 169 patients with predominantly low-grade glioma. RESULTS Correlations between the subjective and the 2 objective cognitive indicators were negligible (0.04) to low (0.24). Objective cognitive deficits were predominantly associated with sociodemographic (older age, lower education, male sex) and clinical (left hemisphere tumor) variables, while lower ratings of subjective cognitive function were more closely related to self-reported mental health symptoms (fatigue, lower mental well-being), physical (motor) dysfunction and female sex. Self-reported communication deficits were associated significantly with both subjective and objective dysfunction. CONCLUSIONS We recommend that both subjective and objective measures of cognitive functioning, together with a measure of psychological distress, be used for comprehensive neuropsychological assessments of patients with glioma to determine which areas are most affected and which specific intervention strategies are most appropriate.

Abstract
We examined the relationship between self-reported and assessed mental health status and service use, using data from the Health and Retirement Study (N = 9,547). Twelve percent and thirty percent had inaccurate perceptions of their mood and memory status, respectively. No significant difference was found in the likelihood of service use between older adults who were unaware of current depressive symptoms and those who self-reported problems but had no assessed symptoms. Older adults who scored low in cognitive test were more likely to use services, regardless of self-reported memory status. Discrepancies between self-reported and assessed status may contribute to service utilization.

Abstract
Object
The purpose of this study was to retrospectively assess the objective and subjective neuropsychological outcome after epilepsy surgery in patients with bilateral Ammon's horn sclerosis (AHS).
Methods
Memory and executive functions were evaluated at baseline and at follow-up in 11 surgically treated patients and compared with 8 pharmacologically treated patients with temporal lobe epilepsy and bilateral AHS. The median follow-up duration was 16 months in the surgically treated patients and 80.5 months in the pharmacologically treated group. Subjective outcome was evaluated by questionnaires and included mood, quality of life, subjective memory, and activities of daily living.
Results
At the follow-up assessment, 82% of the surgically treated patients as opposed to 0% of the nonsurgery patients were seizure free. In the surgical group, nonverbal memory performance did not change significantly in any patient after surgery, but there was a floor effect in 55% of the surgical patients. Regarding verbal memory, 9% of the surgical patients improved while 73% declined, despite severe impairments already evident at baseline. In the nonsurgery control group, 13% of the patients declined in nonverbal memory (floor effect in 63%) and 25% declined in verbal memory (floor effect in 25%) at follow-up. None of the controls improved at follow-up. Executive functions remained unchanged on an impaired level in both groups. At follow-up, the patient groups did not differ significantly with respect to mood, quality of life, subjective memory, or activities of daily living. However, in most aspects, surgically treated patients reported a slightly better subjective outcome than pharmacologically treated patients and a significantly improved quality of life.
Conclusions
These results suggest that beyond benefits concerning seizure control, surgically treated patients with bilateral AHS, despite already poor baseline performance, are still at risk for severe postoperative decline in memory. In the light of predominantly minor benefits on a subjective level, the findings put the overall outcome of epilepsy surgery in bilateral AHS patients into perspective.

Abstract
Cognitive function in idiopathic generalised epilepsies (IGE) is of increasing research attention. Current research seeks to understand phenotypic traits associated with this most common group of inherited epilepsies and evaluate educational and occupational trajectories. A specific deficit in executive function in a subgroup of IGE, juvenile myoclonic epilepsy (JME) has been a particular focus of recent research. This systematic review provides a quantitative synthesis of cognitive function outcomes in 26 peer-reviewed, case-control studies published since 1989. Univariate random-effects meta-analyses were conducted on seven cognitive factor-domains and separately on executive function. Patients with IGE demonstrated significantly lower scores on tests across all cognitive factor-domains except visual-spatial abilities. Effect sizes ranged from 0.42 to 0.88 pooled standard deviation units. The average reduction of scores on tests of executive function in IGE compared to controls was 0.72 standard deviation units. Contrary to current thinking, there was no specific deficit in executive function in JME samples, nor in other IGE syndromes. Of more concern, people with IGE are at risk of pervasive cognitive impairment.

Abstract
Ecological assessment and training of real-life cognitive functions such as visual-spatial abilities in patients with epilepsy remain challenging. Some studies have applied virtual reality (VR) paradigms, but external validity of VR programs has not sufficiently been proven. Patients with focal epilepsy (EG, n=14) accomplished an 8-day program in a VR supermarket, which consisted of learning and buying items on a shopping list. Performance of the EG was compared with that of healthy controls (HCG, n=19). A comprehensive neuropsychological examination was administered. Real-life performance was investigated in a real supermarket. Learning in the VR supermarket was significantly impaired in the EG on different VR measures. Delayed free recall of products did not differ between the EG and the HCG. Virtual reality scores were correlated with neuropsychological measures of visual-spatial cognition, subjective estimates of memory, and performance in the real supermarket. The data indicate that our VR approach allows for the assessment of real-life visual-spatial memory and cognition in patients with focal epilepsy. The multimodal, active, and complex VR paradigm may particularly enhance visual-spatial cognitive resources.

Abstract
Ligands targeting central histamine H3 receptors (H3Rs) for epilepsy might be a promising therapeutic approach. Therefore, the previously described and structurally strongly related imidazole-based derivatives belonging to carbamate class with high H3R in vitro affinity, in-vivo antagonist potency, and H3R selectivity profile were investigated on their anticonvulsant activity in maximal electroshock (MES)-induced and pentylenetetrazole (PTZ)-kindled seizure models in Wistar rats. The effects of systemic injection of H3R ligands 1-13 on MES-induced and PTZ-kindled seizures were screened and evaluated against the reference antiepileptic drug (AED) Phenytoin (PHT) and the standard histamine H3R inverse agonist/antagonist Thioperamide (THP) to determine their potential as new antiepileptic drugs. Following administration of the H3R ligands 1-13 (5, 10 and 15 mg/kg, ip) there was a significant dose dependent reduction in MES-induced seizure duration. The protective action observed for the pentenyl carbamate derivative 4, the most protective H3R ligand among 1-13, was significantly higher (P <0.05) than that of standard H3R antagonist THP, and was reversed when rats were pretreated with the selective H3R agonist R-(α)-methyl-histamine (RAMH) (10mg/kg), or with the CNS penetrant H1R antagonist Pyrilamine (PYR) (10mg/kg). In addition, subeffective dose of H3R ligand 4 (5mg/kg, ip) significantly potentiated the protective action in rats pretreated with PHT (5mg/kg, ip), a dose without appreciable protective effect when given alone. In contrast, pretreatment with H3R ligand 4 (10mg/kg ip) failed to modify PTZ-kindled convulsion, whereas the reference drug PHT was found to fully protect PTZ-induced seizure. These results indicate that some of the investigated imidazole-based H3R ligands 1-13 may be of future therapeutic value in epilepsy.
