Abstract
OBJECTIVE To compare the efficacy and safety of pregabalin and carbamazepine in patients with central post-stroke pain (CPSP). METHODS Patients included in the study were randomly assigned to either flexible-dose pregabalin treatment group or carbamazepine treatment group. The primary efficacy variable was face visual analog scale (F-VAS), the second efficacy assessment was used to assess the effect of treatment on mental health by Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD). RESULTS The mean baseline pain score F-VAS was 6.47 in the pregabalin group and 6.58 in carbamazepine treatment group. F-VAS was significantly lower in the pregabalin group (1.64) than (3.94) carbamazepine treatment group after treatment. Pregabalin was significantly superior to carbamazepine in endpoint assessments on the HAMA and HAMD after treatment. F-VAS and HAMD were showed efficacy as early as week 2 and maintained for whole duration of the study. The average pregabalin dose in the 12-week study was 214.6 (150-375) mg/day. The mean dose (range) of carbamazepine received by the patients was 275.0 (200-400) mg/day. Mild or moderate, typically transient, somnolence and dizziness were the most common adverse events (AES). The differences of the side effects between the two groups were not significant. CONCLUSIONS Pregabalin, but not carbamazepine, may be effective in improving F-VAS, HAMA and HAMD in patients with CPSP.

Janecek JK, Brett BL, Pillay S, Murphy H, Binder JR, Swanson SJ. Cognitive decline and quality of life after resective epilepsy surgery. Epilepsy Behav 2023; 138:109005. [PMID: 36516616 DOI: 10.1016/j.yebeh.2022.109005] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 10/04/2022] [Accepted: 11/17/2022] [Indexed: 12/14/2022]
Abstract
OBJECTIVES The objectives of this study were to examine the association between cognitive decline and quality of life (QoL) change in a large sample of individuals with drug-resistant epilepsy who underwent resective surgery and to examine whether the association between cognitive decline and QoL is differentially affected by seizure classification outcome (Engel Class 1 vs. 2-4) or side of surgery (left vs. right hemisphere). MATERIALS AND METHODS The sample comprised 224 adults (ages ≥ 18) with drug-resistant focal epilepsy treated with resective surgery who underwent comprehensive pre-operative and post-operative evaluations including neuropsychological testing and the Quality of Life in Epilepsy Inventory - 31 between 1991 and 2020. Linear mixed-effects models were fit to examine subject-specific trajectories and assess the effects of time (pre- to post-operative), cognitive decline (number of measures that meaningfully declined), and the interaction between time and cognitive decline on pre- to post-operative change in QoL. RESULTS Increases in QoL following resection were observed (B = -10.72 [SE = 1.22], p < .001; mean difference between time point 1 and time point 2 QoL rating = 8.11). There was also a main effect of cognitive decline on QoL (B = -.85 [SE = .27], p = .002). Follow-up analyses showed that the number of cognitive measures that declined was significantly associated with post-surgical QoL, (r = -.20 p = .003), but not pre-surgical QoL, (r = -.04 p = .594), and with pre-to post-surgery raw change in QoL score, (r = -.18 p = .009). A cognitive decline by time point interaction was observed, such that those who had greater cognitive decline had less improvement in overall QoL following resection (B = .72 [SE = .27], p = .009). Similar results were observed within the Engel Class 1 outcome subgroup. However, within the Engel Class 2-4 outcome subgroup, QoL improved following resection, but there was no main effect of cognitive decline or interaction between cognitive decline and time point on QoL change. There was no main effect of resection hemisphere on overall QoL, nor were there interactions with hemisphere by time, hemisphere by cognitive decline, or hemisphere by time by cognitive decline. CONCLUSIONS Quality of life improves following epilepsy surgery. Participants who had cognitive decline across a greater number of measures experienced less improvement in QoL post-operatively overall, but there was no clear pattern of domain-specific cognitive decline associated with change in QoL. Our results indicate that cognitive decline in a diffuse set of cognitive domains negatively influences post-operative QoL, particularly for those who experience good seizure outcomes (i.e., seizure freedom), regardless of the site or side of resection.

Systematic review of frequency of felt and enacted stigma in epilepsy and determining factors and attitudes toward persons living with epilepsy-Report from the International League Against Epilepsy Task Force on Stigma in Epilepsy. Epilepsia 2022; 63:573-597. [PMID: 34985782 DOI: 10.1111/epi.17135] [Citation(s) in RCA: 36] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 11/09/2021] [Accepted: 11/10/2021] [Indexed: 11/25/2022]
Abstract
OBJECTIVE To review the evidence of felt and enacted stigma and attitudes toward persons living with epilepsy, and their determining factors. METHODS Thirteen databases were searched (1985-2019). Abstracts were reviewed in duplicate and data were independently extracted using a standardized form. Studies were characterized using descriptive analysis by whether they addressed "felt" or "enacted" stigma and "attitudes" toward persons living with epilepsy. RESULTS Of 4234 abstracts, 132 met eligibility criteria and addressed either felt or enacted stigma and 210 attitudes toward epilepsy. Stigma frequency ranged broadly between regions. Factors associated with enacted stigma included low level of knowledge about epilepsy, lower educational level, lower socioeconomic status, rural areas living, and religious grouping. Negative stereotypes were often internalized by persons with epilepsy, who saw themselves as having an "undesirable difference" and so anticipated being treated differently. Felt stigma was associated with increased risk of psychological difficulties and impaired quality of life. Felt stigma was linked to higher seizure frequency, recency of seizures, younger age at epilepsy onset or longer duration, lower educational level, poorer knowledge about epilepsy, and younger age. An important finding was the potential contribution of epilepsy terminology to the production of stigma. Negative attitudes toward those with epilepsy were described in 100% of included studies, and originated in any population group (students, teachers, healthcare professionals, general public, and those living with epilepsy). Better attitudes were generally noted in those of younger age or higher educational status. SIGNIFICANCE Whatever the specific beliefs about epilepsy, implications for felt and enacted stigma show considerable commonality worldwide. Although some studies show improvement in attitudes toward those living with epilepsy over time, much work remains to be done to improve attitudes and understand the true occurrence of discrimination against persons with epilepsy.

Abstract
OBJECTIVE This is a systematic review aimed at summarizing the evidence related to instruments that have been developed to measure stigma or attitudes toward epilepsy and on stigma-reducing interventions. METHODS This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. A broad literature search (1985-2019) was performed in 13 databases. Articles were included if they described the development and testing of psychometric properties of an epilepsy-related stigma or attitude scale or stigma-reducing interventions. Two reviewers independently screened abstracts, reviewed full-text articles, and extracted data. Basic descriptive statistics are reported. RESULTS We identified 4234 abstracts, of which 893 were reviewed as full-text articles. Of these, 38 met inclusion criteria for an instrument development study and 30 as a stigma-reduction intervention study. Most instruments were initially developed using well-established methods and were tested in relatively large samples. Most intervention studies involved educational programs for adults with pre- and post-evaluations of attitudes toward people with epilepsy. Intervention studies often failed to use standardized instruments to quantify stigmatizing attitudes, were generally underpowered, and often found no evidence of benefit or the benefit was not sustained. Six intervention studies with stigma as the primary outcome had fewer design flaws and showed benefit. Very few or no instruments were validated for regional languages or culture, and there were very few interventions tested in some regions. SIGNIFICANCE Investigators in regions without instruments should consider translating and further developing existing instruments rather than initiating the development of new instruments. Very few stigma-reduction intervention studies for epilepsy have been conducted, study methodology in general was poor, and standardized instruments were rarely used to measure outcomes. To accelerate the development of effective epilepsy stigma-reduction interventions, a paradigm shift from disease-specific, siloed trials to collaborative, cross-disciplinary platforms based upon unified theories of stigma transcending individual conditions will be needed.

Health-related quality of life after epilepsy surgery: A prospective, controlled follow-up on the Iranian population. Sci Rep 2019; 9:7875. [PMID: 31133687 PMCID: PMC6536509 DOI: 10.1038/s41598-019-44442-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2018] [Accepted: 05/13/2019] [Indexed: 01/03/2023] Open
Abstract
Quality of life is affected by factors such as regional differences in access to treatment choices, and rehabilitation. This study aims to assess the result of epilepsy surgery and its impact on QoL in Iran. The data for 60 patients who underwent epilepsy surgery in Loghman-Hakim hospital between 2003 to 2017 were analyzed prospectively through clinical observation. Clinical variables of interest and the WHOQOL-BREF scale to assess QoL were applied. Scores of operated patients were compared to their preoperative scores as well as epileptic patients controlled with antiepileptic drugs (AEDs) and healthy individuals. The mean age of surgery group patients was 33.78 (34 male; 26 female). Twenty seven patients underwent temporal mesial lobectomy, 20 anterior callosotomy, and 13 neocortical resections. The average QoL score in healthy group was 72.48, in AEDs controls was 56.16, and in operated patients was 65.61. In addition, analysis showed a significant increase in postoperative QoL of the surgical group compared to the AEDs controls. Epilepsy surgery could be the best approach in patients suffering from drug-resistant epilepsy even in developing countries, which can result in seizure relief and a reduction in the frequency of disabling seizures.

Abstract
INTRODUCTION Epilepsy has several comorbidities and associated stigma. Stigma associated with epilepsy is well known and prevalent worldwide. Surgical treatment is an established treatment for drug refractory epilepsy. Following surgery in children, it is possible that the stigma may reduce, but such an effect has not been studied earlier. MATERIALS AND METHODS Analysis of prospectively collected data was performed for pediatric patients at a single tertiary center for treating epilepsy. Child stigma scale, as described by Austin et al., was used to evaluate stigma both pre- and postoperatively. Analysis was done using Paired t test. RESULTS In this study, following surgery, there was significant reduction of stigma (P<0.001). This was proportional to the reduction in seizures, though there were 9 (30%) patients, who due to persistent neurodisability did not have any reduction of stigma despite having good seizure outcome. CONCLUSION Surgery in drug-resistant epilepsy helps in reducing stigma. Seizure reduction is probably not the only factor responsible for a change in stigma outcome.

Abstract
Surgery for refractory epilepsy is widely used but the efficacy of this treatment for providing a seizure-free outcome and better quality of life remains unclear.This study aimed to update current evidence and to evaluate the effects of surgery on quality of life in patients with refractory epilepsy.A systematic review and meta-analysis of the literature were conducted and selected studies included 2 groups of refractory epilepsy patients, surgical and nonsurgical.The studies were assessed using the Newcastle-Ottawa Scale. The primary outcome was the seizure-free rate. The secondary outcome was quality of life. Adverse events were also reviewed.After screening, a total of 20 studies were selected: 8 were interventional, including 2 randomized controlled trials, and 12 were observational. All of the studies comprised 1959 patients with refractory epilepsy. The seizure-free rates were significantly higher for patients who received surgery compared with the patients who did not; the combined odds ratio was 19.35 (95% CI = 12.10-30.95, P < 0.001). After adjusting for publication bias the combined odds ratio was 10.25 (95% CI = 5.84-18.00). In both the interventional and observational studies, patients treated surgically had a significantly better quality of life compared with the patients not treated surgically. Complications were listed in 3 studies and the rates were similar in surgical and nonsurgical patients.Our meta-analysis found that for patients with refractory epilepsy, surgical treatment appears to provide a much greater likelihood of seizure-free outcome than nonsurgical treatment, although there is a need for more studies, particularly randomized studies, to confirm this conclusion. Based on more limited data, surgical treatment also appeared to provide a better quality of life and did not seem to increase complications.

Abstract
OBJECTIVE Although a number of epidemiologic studies have been conducted on the prevalence and incidence of epilepsy around the world, only a few studies have investigated the clinical characteristics of patients with epilepsy in a population-based sample. The purpose of the present study was to describe the clinical characteristics of treated patients with epilepsy in Korea via a nationwide medical records survey. METHODS The study population was obtained through a nationwide database registered to the Health Insurance Review and Assessment service. Patients were recruited from clinics and hospitals in each cluster according to region and referral level by random selection from a preallocated sample of patients. All patients were being treated with antiepileptic drug medication with or without a diagnosis code for epilepsy or seizure between January 2009 and December 2009. Among the 6,436 selected patients, 2,150 met the diagnostic criteria for epilepsy and were included in our survey on the clinical characteristics of patients who were with treated epilepsy. RESULTS The proportion of male patients with epilepsy in this study was higher (1,226; 57.0%) than that of female patients. In addition, 10.6% of patients were first diagnosed with epilepsy in 2009, and 53.6% of patients experienced at least one seizure over the course of 2009; 78.1% were classified as having localization-related epilepsy, whereas 7.3% were considered to have generalized epilepsy. Thirty-five percent of patients were thus classified as idiopathic or cryptogenic cases. The most common cause of symptomatic epilepsy was trauma (10.0%), followed by stroke (9.6%), central nervous system (CNS) infection (5.7%), and hippocampal sclerosis (4.9%). SIGNIFICANCE This is the first nationwide study of the clinical characteristics of treated epilepsy in Korea using a national database validated by medical records survey. The etiologies of epilepsy and epilepsy syndrome classifications were comparable to those previously reported in other developed countries.

High-frequency oscillations, extent of surgical resection, and surgical outcome in drug-resistant focal epilepsy. Epilepsia 2013; 54:848-57.

Abstract
PURPOSE Removal of areas generating high-frequency oscillations (HFOs) recorded from the intracerebral electroencephalography (iEEG) of patients with medically intractable epilepsy has been found to be correlated with improved surgical outcome. However, whether differences exist according to the type of epilepsy is largely unknown. We performed a comparative assessment of the impact of removing HFO-generating tissue on surgical outcome between temporal lobe epilepsy (TLE) and extratemporal lobe epilepsy (ETLE). We also assessed the relationship between the extent of surgical resection and surgical outcome. METHODS We studied 30 patients with drug-resistant focal epilepsy, 21 with TLE and 9 with ETLE. Two thirds of the patients were included in a previous report and for these, clinical and imaging data were updated and follow-up was extended. All patients underwent iEEG investigations (500 Hz high-pass filter and 2,000 Hz sampling rate), surgical resection, and postoperative magnetic resonance imaging (MRI). HFOs (ripples, 80-250 Hz; fast ripples, >250 Hz) were identified visually on a 5-10 min interictal iEEG sample. HFO rates inside versus outside the seizure-onset zone (SOZ), in resected versus nonresected tissue, and their association with surgical outcome (ILAE classification) were assessed in the entire cohort, and in the TLE and ETLE subgroups. We also tested the correlation of resected brain hippocampal and amygdala volumes (as measured on postoperative MRIs) with surgical outcome. KEY FINDINGS HFO rates were significantly higher inside the SOZ than outside in the entire cohort and TLE subgroup, but not in the ETLE subgroup. In all groups, HFO rates did not differ significantly between resected and nonresected tissue. Surgical outcome was better when higher HFO rates were included in the surgical resection in the entire cohort and TLE subgroup, but not in the ETLE subgroup. Resected brain hippocampal and amygdala volumes were not correlated with surgical outcome. SIGNIFICANCE In TLE, removal of HFO-generating areas may lead to improved surgical outcome. Less consistent findings emerge from ETLE, but these may be related to sample size limitations of this study. Size of resection, a factor that was ignored and that could have affected results of earlier studies did not influence results.

Abstract
OBJECTIVES To investigate the characteristics and prevalence of poststroke depression (PSD) and poststroke emotional incontinence (PSEI) and the factors related to these conditions at admission and 3 months after stroke. METHODS We evaluated 508 consecutive patients with acute ischemic stroke for PSD and PSEI at admission and 3 months later. PSD was evaluated using the Beck Depression Inventory, and PSEI was evaluated using Kim's criteria. Blood samples were collected and genotyped for the promoter region of the serotonin transporter protein (5-HTTLPR) and the number of tandem repeats within intron 2 (STin2 VNTR). Perceived social support (the ENRICHD Social Support Inventory) was also measured. RESULTS PSD and PSEI were present in 13.7% and 9.4% of patients, respectively, at admission and in 17.7% and 11.7%, respectively, at 3 months after stroke. Multivariate analyses showed that PSD at admission was associated with the NIH Stroke Scale score at admission (p < 0.001), whereas PSD at 3 months was associated with the presence of microbleeds (p < 0.01) and perceived low social support (p < 0.001). In contrast, only lesion location (p = 0.022) was associated with PSEI at admission, whereas modified Rankin Scale score (p = 0.019), STin2 VNTR (p = 0.040), and low social support (p = 0.042) were related to PSEI 3 months after stroke. CONCLUSIONS Diverse factors such as neurologic dysfunction, lesion location, microbleeds, genetic traits, and social support are differently related to acute and subacute emotional disturbances. Strategies to prevent or manage these problems should consider these differences.

Safety and efficacy of pregabalin in patients with central post-stroke pain. Pain 2011; 152:1018-1023. [PMID: 21316855 DOI: 10.1016/j.pain.2010.12.023] [Citation(s) in RCA: 78] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2010] [Revised: 11/08/2010] [Accepted: 12/14/2010] [Indexed: 11/24/2022]
Abstract
Pregabalin has demonstrated efficacy in several forms of neuropathic pain, but its long-term efficacy in central post-stroke pain (CPSP) is unproven. We evaluated the efficacy and safety of pregabalin versus placebo in patients with CPSP. A 13-week, randomized, double-blind, multicenter, placebo-controlled, parallel group study of 150 to 600 mg/day pregabalin was conducted in patients aged ≥18 years with CPSP. The primary efficacy endpoint was the mean pain score on the Daily Pain Rating Scale over the last 7 days on study drug up to week 12 or early termination visit. Secondary endpoints included other pain parameters and patient-reported sleep and health-related quality-of-life measures. A total of 219 patients were treated (pregabalin n=110; placebo n=109). A mean pain score at baseline of 6.5 in the pregabalin group and 6.3 in the placebo group reduced at endpoint to 4.9 in the pregabalin group and 5.0 in the placebo group (LS mean difference=-0.2; 95% CI=-0.7, 0.4; P=0.578). Treatment with pregabalin resulted in significant improvements, compared with placebo, on secondary endpoints including MOS-sleep, HADS-A anxiety, and clinician global impression of change (CGIC) P<0.05. Adverse events were more frequent with pregabalin than with placebo and caused discontinuation in 9 (8.2%) of pregabalin patients versus 4 (3.7%) of placebo patients. Although pain reductions at endpoint did not differ significantly between pregabalin and placebo, improvements in sleep, anxiety, and CGIC suggest some utility of pregabalin in the management of CPSP.

[PMID: 21212026 DOI: 10.1016/j.yebeh.2010.11.018] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2010] [Revised: 11/17/2010] [Accepted: 11/20/2010] [Indexed: 11/16/2022]
Abstract
The aim of this study was to investigate the frequencies of and barriers to leisure time physical activity (LTPA) of people with epilepsy (PWE), and influencing factors, particularly those related to mood. Data were obtained from 178 PWE who visited the Seoul National University Hospital outpatient clinic in January and February 2007. Most PWE reported not being involved in LTPA as much as they wished. PWE reported hiking (n=32, 18%) and walking (n=25, 14%) as the most common LTPA. Many PWE identified epilepsy-specific barriers such as "the fear of experiencing seizures during activity" and "discouragement from activity by family and/or friends." In multiple logistic regression analysis, PWE who were on antiepileptic drug polytherapy (OR=2.49, 95% CI=1.22-5.08, P=0.01), had anxiety (OR=3.25, 95% CI=1.22-8.60, P=0.02), and had had previous seizure experiences during activities (OR=2.84, 95% CI=1.30-6.20, P=0.01) were significantly more likely to be inactive. Educational programs for reducing anxiety and misunderstanding about activity of PWE and guidelines for promoting LTPA among PWE are needed.

Abstract
Aggressive versus limited resection is an often-debated topic in epilepsy surgery. There are two inherent questions within this debate: (1) Can a more limited resection yield seizure freedom rates similar to those afforded by wider/more aggressive resection, with lower rates of neurological complications? (2) Does wider/more aggressive resection increase seizure freedom rates, with tolerable neurological complications rates? Further, if more limited resection has a lower seizure freedom rate, but fewer complications, is quality of life better or worse than that following a wider/more aggressive resection that increases seizure freedom rate but yields a higher complication rate? Here, we review the literature to address these questions. Because most studies are retrospective observational studies, with limited statistical power to draw strong conclusions, there is a need for more randomized prospective multicenter clinical trials incorporating advances in technique for identifying the seizure onset zone (e.g., subtractive ictal SPECT) and tissue at risk (e.g., diffusion tensor imaging) to inform this discussion.

Abstract
PURPOSE To describe the concerns of Korean adults living with epilepsy and to compare the concerns of individuals with controlled and uncontrolled seizures. METHODS Outpatients filled out questionnaires, including the Hospital Anxiety and Depression Scale, the Quality of Life in Epilepsy-10 questionnaire, the stigma scale, and a questionnaire on episodes of discrimination. Patients were asked to fill out the Epilepsy Foundation of America (EFA) Concerns Index and to list their concerns on a blank sheet of paper. RESULTS Of the 178 participants, 152 described a total of 470 concerns, which could be assorted into 25 distinct concerns. Worrying about the hereditability of their condition was the only concern that differed significantly between individuals with controlled and uncontrolled seizures. Three significant factors were identified on the total EFA Concerns Index score: level of anxiety/depression (34.4%), age (6.3%), and degree of social discrimination (4.3%), resulting in a total explained variance of 45.0%. CONCLUSIONS Korean adults with epilepsy had various concerns, with some differing from those in Western populations. Anxiety/depression, age and degree of discrimination were significantly associated with the degree of concern in Korean patients with epilepsy.
