Discontinuation of Antiseizure Medications in Patients With Brain Tumors. Neurology 2024; 102:e209163.

Abstract
Patients with brain tumors will experience seizures during their disease course. While providers can use antiseizure medications to control these events, patients with brain tumors can experience side effects, ranging from mild to severe, from these medications. Providers in subspecialties such as neurology, neuro-oncology, neurosurgery, radiation oncology, and medical oncology often work with patients with brain tumor to balance seizure control and the adverse toxicity of antiseizure medications. In this study, we sought to explore the problem of brain tumor-related seizures/epilepsy in the context of how and when to consider antiseizure medication discontinuation. Moreover, we thoroughly evaluate the literature on antiseizure medication discontinuation for adult and pediatric patients and highlight recommendations relevant to patients with both brain tumors and seizures.

Abstract
OBJECTIVE We investigated adult-onset epilepsy as a risk factor for the development of substance use disorder (SUD) by comparing the rate of SUD diagnosis among adults diagnosed with epilepsy with presumably healthy controls with lower extremity fractures (LEF). For additional comparison, we investigated the risk for adults with migraine only. Epilepsy and migraine are both episodic neurological disorders and migraine is frequently comorbid with epilepsy. METHODS We conducted a time-to-event analysis using a subset of surveillance data of hospital admissions, emergency department visits, and outpatient visits in South Carolina, USA from January 1, 2000, through December 31, 2011. Individuals aged 18 years or older were identified using the International Classification of Disease, 9thRevision Clinical Modification (ICD-9) with a diagnosis of epilepsy (n = 78,547; 52.7% female, mean age 51.3 years), migraine (n = 121,155; 81.5% female, mean age 40.0 years), or LEF (n = 73,911; 55.4% female, mean age 48.7 years). Individuals with SUD diagnosis following epilepsy, migraine, or LEF were identified with ICD-9 codes. We used Cox proportional hazards regression to model the time to SUD diagnosis comparing adults diagnosed with epilepsy, migraine, and LEF, adjusting for insurance payer, age, sex, race/ethnicity, and prior mental health comorbidities. RESULTS Compared to LEF controls, adults with epilepsy were diagnosed with SUD at 2.5 times the rate [HR 2.48 (2.37, 2.60)] and adults with migraine only were diagnosed with SUD at 1.12 times the rate [HR 1.12 (1.06, 1.18)]. We found an interaction between disease diagnosis and insurance payer, with hazard ratios comparing epilepsy to LEF of 4.59, 3.48, 1.97, and 1.44 within the commercial payer, uninsured, Medicaid, and Medicare strata, respectively. SIGNIFICANCE Compared to presumably healthy controls, adults with epilepsy had a substantially higher hazard of SUD, while adults with migraine only showed a small, but significant, increased hazard of SUD.

Incidence of and predictors for antiseizure medication gaps in Medicare beneficiaries with epilepsy: a retrospective cohort study. BMC Neurol 2022; 22:328. [PMID: 36050646 PMCID: PMC9434838 DOI: 10.1186/s12883-022-02852-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Accepted: 08/25/2022] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND For the two-thirds of patients with epilepsy who achieve seizure remission on antiseizure medications (ASMs), patients and clinicians must weigh the pros and cons of long-term ASM treatment. However, little work has evaluated how often ASM discontinuation occurs in practice. We describe the incidence of and predictors for sustained ASM fill gaps to measure discontinuation in individuals potentially eligible for ASM withdrawal. METHODS This was a retrospective cohort of Medicare beneficiaries. We included patients with epilepsy by requiring International Classification of Diseases codes for epilepsy/convulsions plus at least one ASM prescription each year 2014-2016, and no acute visit for epilepsy 2014-2015 (i.e., potentially eligible for ASM discontinuation). The main outcome was the first day of a gap in ASM supply (30, 90, 180, or 360 days with no pills) in 2016-2018. We displayed cumulative incidence functions and identified predictors using Cox regressions. RESULTS Among 21,819 beneficiaries, 5191 (24%) had a 30-day gap, 1753 (8%) had a 90-day gap, 803 (4%) had a 180-day gap, and 381 (2%) had a 360-day gap. Predictors increasing the chance of a 180-day gap included number of unique medications in 2015 (hazard ratio [HR] 1.03 per medication, 95% confidence interval [CI] 1.01-1.05) and epileptologist prescribing physician (≥25% of that physician's visits for epilepsy; HR 2.37, 95% CI 1.39-4.03). Predictors decreasing the chance of a 180-day gap included Medicaid dual eligibility (HR 0.75, 95% CI 0.60-0.95), number of unique ASMs in 2015 (e.g., 2 versus 1: HR 0.37, 95% CI 0.30-0.45), and greater baseline adherence (> 80% versus ≤80% of days in 2015 with ASM pill supply: HR 0.38, 95% CI 0.32-0.44). CONCLUSIONS Sustained ASM gaps were rarer than current guidelines may suggest. Future work should further explore barriers and enablers of ASM discontinuation to understand the optimal discontinuation rate.

Reappraisal of the Medical Research Council Antiepileptic Drug Withdrawal Study: contamination‐adjusted and dose‐response re‐analysis. Epilepsia 2022; 63:1724-1735. [PMID: 35490396 PMCID: PMC9283317 DOI: 10.1111/epi.17273] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 04/27/2022] [Accepted: 04/27/2022] [Indexed: 11/28/2022]
Abstract
Objective The 1991 Medical Research Council (MRC) Study compared seizure relapse for seizure‐free patients randomized to withdraw vs continue of antiseizure medications (ASMs). We re‐analyzed this trial to account for crossover between arms using contamination‐adjusted intention to treat (CA ITT) methods, to explore dose‐response curves, and to validate predictions against external data. ITT assesses the effect of being randomized to withdraw, as‐treated analysis assesses the confounded effect of withdrawing, but CA ITT assesses the unconfounded effect of actually withdrawing. Methods CA ITT involves two stages. First, we used randomized arm to predict whether patients withdrew their ASM (logistic) or total daily ASM dose (linear). Second, we used those values to predict seizure occurrence (logistic). Results The trial randomized 503 patients to withdraw and 501 patients to continue ASMs. We found that 316 of 376 patients (88%) who were randomized to withdraw decreased their dose at every pre‐seizure visit, compared with 35 of 424 (8%) who were randomized to continue (p < .01). Adjusted odds ratios of a 2‐year seizure for those who withdrew vs those who did not was 1.3 (95% confidence interval [CI] 0.9–1.9) in the as‐treated analysis, 2.5 (95% CI 1.9–3.4) comparing those randomized to withdraw vs continue for ITT, and 3.1 (95% CI 2.1–4.5) for CA ITT. Probabilities (withdrawal vs continue) were 28% vs 24% (as‐treated), 40% vs 22% (ITT), and 43% vs 21% (CA ITT). Differences between ITT and CA ITT were greater when varying the predictor (reaching zero ASMs) or outcome (1‐year seizures). As‐treated dose‐response curves demonstrated little to no effects, but larger effects in CA ITT analysis. MRC data overpredicted risk in Lossius data, with moderate discrimination (areas under the curve ~0.70). Significance CA ITT results (the effect of actually withdrawing ASMs on seizures) were slightly greater than ITT effects (the effect of recommend withdrawing ASMs on seizures). How these findings affect clinical practice must be individualized.

Personality changes in patients suffering from drug-resistant epilepsy after surgical treatment: a 1-year follow-up study. Epilepsy Res 2021; 177:106784. [PMID: 34688182 DOI: 10.1016/j.eplepsyres.2021.106784] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 09/29/2021] [Accepted: 10/04/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To determine changes in dimensions of personality in a sample of patients suffering from drug-resistant epilepsy at the 1-year follow-up following surgery, compared to non-surgically treated controls. METHODS We conducted a prospective comparative controlled study, including drug-resistant epilepsy surgery candidates. Demographic, psychiatric, neurological, and psychological data were recorded. Presurgical and 12-months follow-up evaluations were performed. Personality dimensions were measured by the NEO Five-Factor Inventory, Revised version (NEO-FFI-R), anxiety and depression symptoms were assessed by the Hospital Anxiety and Depression Scale (HADS: HADA-Anxiety and HADD-Depression), psychiatric evaluations were performed using the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) Axis-I disorders classification. Statistical analysis consisted of comparative tests, correlation analysis, and the stepwise multiple regression test (ANOVA). RESULTS A 1-year follow-up was completed by 70 out of 80 patients. Through the study, the surgical group decreased in neuroticism and increased in agreeableness. The controls increased in consciousness, and these changes were predicted by the earlier age of epilepsy onset and lesser score in HADD at the baseline. No personality changes were associated with seizure frequency. The presurgical evaluation concluded that both groups had no differences in demographic, psychiatric, or neurological variables with the only exception being for the number of seizures per month, which was higher in the surgical group. Psychiatric comorbidity in patients was associated with their higher degree of neuroticism and agreeableness at the baseline. Comparing control and surgical groups at the one-year follow-up, the agreeableness personality variable was higher in the surgical group, and as expected, HADS scores were higher in the control group, and seizure frequency was also higher in the control group. SIGNIFICANCE Higher agreeableness was the most relevant difference in personality dimensions in patients who underwent surgical treatment compared with the non-surgical treatment group. After surgery patients decreased in neuroticism and increased in agreeableness scores.

Chu SS, Tan G, Wang XP, Liu L. Validation of the predictive model for seizure recurrence after withdrawal of antiepileptic drugs. Epilepsy Behav 2021; 114:106987. [PMID: 32444329 DOI: 10.1016/j.yebeh.2020.106987] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2019] [Revised: 01/14/2020] [Accepted: 02/17/2020] [Indexed: 02/08/2023]
Abstract
PURPOSE The purpose of this study was to validate the practicability of Lamberink's prediction model in risk assessment of antiepileptic drug (AED) withdrawal in a real, seizure-free population and to find a practical cutoff value to guide clinical withdrawal. METHODS A group of seizure-free patients from West China Hospital was recruited. Each patient had been seizure-free for at least two years. The seizure recurrence risk among the patients was calculated by an online AED withdrawal risk calculator. The predictive ability of Lamberink's model was assessed by analyzing discrimination and calibration with receiver operating characteristic (ROC) curves and calibration plots, respectively. RESULTS A total of 184 seizure-free patients received risk evaluation, all of whom were followed up for at least two years or had an earlier report of seizure relapse. Of these patients, 128 patients were followed up for at least five years or had an earlier report of relapse within five years. Sixty-two of 184 (33.7%) patients relapsed within two years, while 81 of 184 (44.0%) patients relapsed within five years after the start of AEDs' withdrawal. Cox regression analyses showed that seizure duration before remission and the age of seizure onset were independent predictors of relapse at two years. For predictors of recurrence at five years, seizure duration before remission, age at onset, and withdrawal were significant. For discrimination, ROC curve analysis showed that the area under the curve (AUC) for the seizure recurrence within two and five years was 0.605 (95% confidence interval [CI]: 0.518-0.692, p = 0.02) and 0.656 (95% CI: 0.563-0.749, p = 0.003), respectively. For calibration, it was poor in two-year prediction; the observed number was considerably lower than the predicted number. However, the calibration plot showed good calibration with the five-year prediction except for the second, fourth, and eighth deciles. With a cutoff two-year recurrence risk of 47%, the model had a sensitivity of 0.758 and a specificity of 0.410; the largest Youden index was 1.168. With a cutoff five-year recurrence risk of 77%, the model had a sensitivity of 0.358 and a specificity of 0.979; the largest Youden index was 1.337. CONCLUSIONS Lamberink's prediction model has a general discrimination ability. The model overestimated the actual recurrence events when predicting the two-year recurrence risk, but it showed relatively good calibration with five-year prediction. The cutoff value found in this study may be used to guide patients and clinicians towards a decision regarding the withdrawal of AEDs. The model appears to be a useful tool for predicting seizure recurrence for the five-year recurrence risk.

Abstract
OBJECTIVE The objective of this study was to explore the prevalence and predictors of limitations causing disability in patients treated for seizures or epilepsy compared with patients without epilepsy. METHODS This was a retrospective cross-sectional study using the National Health and Nutrition Examination Survey (NHANES). We included all participants ≥20 years old for 2013-2018. We classified patients as having epilepsy if they reported taking at least one prescription medication to treat seizures or epilepsy. Physical, mental, and social limitations were determined from interview questions. We report the prevalence of any limitation and total number of limitations for participants without vs. with epilepsy using serial negative binomial regressions and severity of individual limitations according to epilepsy status. RESULTS We included 17,057 participants, of whom 148 (0.8%) had epilepsy. Overall, 80% (95% confidence interval [CI]: 73%-86%) with epilepsy vs. 38% (95% CI: 36%-39%) without epilepsy reported at least 1 limitation (p < 0.01). The mean number of limitations was 7.5 (95% CI: 6.2-8.8) for those with epilepsy vs. 2.4 (95% CI: 2.3-2.6) for those without epilepsy (p < 0.01). Epilepsy was associated with an incidence rate ratio (IRR) of 3.1 (95% CI: 2.6-3.7) in an unadjusted negative binomial regression. After adjusting for demographics and comorbidities, this association was no longer significant (IRR: 1.2, 95% CI: 0.9-1.7). Limitations cited by 40-50% of participants with epilepsy included stooping/kneeling/crouching, standing for long periods of time, and pushing/pulling objects. Limitation severity was consistently higher in patients with epilepsy. CONCLUSIONS Patients with epilepsy had 3.1 times as many physical, mental, or social limitations compared with those without epilepsy, and disability severity was consistently higher. This effect was attenuated after considering baseline variables such as smoking and depression severity. Our work implies the importance of structured mental health screening and self-management programs targeting mood, weight, and lifestyle as potential leverage points towards alleviating epilepsy-related disability.

Abstract
OBJECTIVE The objective of the study was to characterize the prevalence of polypharmacy and central nervous system (CNS)-acting medications in patients with epilepsy, and particular types of medications. METHODS This was a retrospective cross-sectional study using data from the nationally representative National Health and Nutrition Examination Survey (NHANES). We included patients who reported taking at least one prescription medication in order to treat seizures or epilepsy during NHANES survey years 2013-2016. We assessed the number and types of drugs and predictors of total number of medications using a negative binomial regression. We then assessed prevalence of polypharmacy (≥5 medications), CNS polypharmacy (≥3 CNS-acting medications) and additional CNS-acting medications, and drugs that lower the seizure threshold (i.e., bupropion and tramadol), and extrapolated prevalence to estimated affected US population. RESULTS The NHANES contained 20,146 participants, of whom 135 reported taking ≥1 antiseizure medication (ASM) for seizures or epilepsy representing 2,399,520 US citizens using NHANES's sampling frame. Patients reported taking a mean 5.3 (95% confidence interval (CI): 4.3-6.3) prescription medications. Adjusting for race, sex, and uninsurance, both age and number of chronic conditions predicted increased number of medications (incident rate ratio (IRR) per decade: 1.16, 95% CI: 1.04-1.28; IRR per chronic condition: 1.19, 95% CI: 1.11-1.27). Polypharmacy was reported by 47% (95% CI: 38%-57%) of patients, CNS polypharmacy by 34% (23%-47%), benzodiazepine use by 21% (14%-30%), opioid use by 16% (11%-24%), benzodiazepine plus opioid use by 6% (3%-14%), and 6% (2%-15%) reported a drug that lowers the seizure threshold. Twelve percent (7%-20%) took an opioid with either a benzodiazepine or gabapentinoid. CONCLUSIONS Polypharmacy is common in patients with epilepsy. Patients taking ASMs frequently reported also taking other CNS-acting medications (i.e., opioids, benzodiazepines, seizure threshold-lowering medications), and medication combinations with black box warnings. Central nervous system polypharmacy poses health risks. Future research is needed to explore drivers of polypharmacy and strategies to help mitigate potentially harmful prescription use in this high-risk population.

[PMID: 31726286 DOI: 10.1016/j.eplepsyres.2019.106219] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2019] [Revised: 09/27/2019] [Accepted: 10/15/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND PURPOSE Efficacy of sodium valproate in epilepsy is limited by its poor blood brain barrier penetration and side effects. Nanoparticles may offer a better drug delivery system to overcome these limitations. This study evaluated the efficacy of sodium valproate encapsulated in nanoparticles in pentylenetetrazole (PTZ) induced acute and kindling models of seizures in male Wistar rats. METHODS Poly lactic-co-glycolic acid (PLGA) based, polysorbate 80 stabilized sodium valproate loaded nanoparticles (nano sodium valproate) and rhodamine loaded nanoparticles (RLN) were formulated by double emulsion- solvent evaporation method and characterized for their size, shape, zeta potential and drug loading percentage. RLN was used to demonstrate blood brain barrier (BBB) permeability of nanoparticles. Serum drug levels were estimated using high performance liquid chromatography. The efficacy of standard sodium valproate (300 mg/kg) and nano sodium valproate (∼300, ∼150 and ∼75 mg/kg of sodium valproate) were evaluated in experimental animal models of seizures along with their effects on behavioral and oxidative stress parameters. Drugs were administered 60 min before PTZ in acute model. In the kindling model, drugs were administered every day while PTZ was administered on alternate days 60 min after drug administration. All the study drugs/compounds were administered intraperitoneally. RESULTS RLN were observed to be clustered in cortex which implied that the nanoparticles crossed BBB. Both standard sodium valproate and nano sodium valproate reached therapeutic serum level at 15 min and 1 h, but were undetectable in serum at 24 h. In acute PTZ (60 mg/kg) model, nano sodium valproate (∼300 mg/kg of sodium valproate) and standard sodium valproate showed protection against seizures till 6 h and 4 h, respectively. There were significant behavioral impairment and oxidative stress with standard sodium valproate in acute model as compared to nano sodium valproate at 6 h. In kindling model, induced with PTZ (30 mg/kg, every alternate day for 42 days), complete protection from seizures was observed with nano sodium valproate (∼150 mg/kg and ∼75 mg/kg of sodium valproate) and standard sodium valproate (300 mg/kg). Similarly, significant protection from behavioral impairment and oxidative stress was observed with standard sodium valproate and nano sodium valproate as compared to PTZ. CONCLUSION When compared to conventional therapy, nano sodium valproate showed protection from seizures at reduced doses and for a longer duration in animal models of epilepsy. This study suggests the potential of nano sodium valproate in the treatment of epilepsy.

Abstract
PURPOSE OF REVIEW As the number of patients diagnosed with epilepsy continues to rise and the pharmacological and device-based treatment options for epilepsy increase, determining when to stop antiepileptic drug (AED) treatment continues to be an important issue for patient management and counseling. RECENT FINDINGS This review focuses on outcomes following AED withdrawal in seizure-free adults with epilepsy. Practical considerations are also discussed because, despite the importance of this topic, relatively little progress has been made in the past year regarding the identification of patients whose risk for recurrent seizures after AED withdrawal is no higher than that of the general population. SUMMARY Although articles in the past year have updated the debates about whether and when to discontinue AEDs in seizure-free adults and have suggested potential utility for electroencephalograms as a prognostic tool for AED reduction as well as for an AED withdrawal risk calculator, decisions about AED withdrawal should still be based on the known risks and consequences of seizure recurrence and be made following well documented discussions between doctor and patient/carer.

Abstract
OBJECTIVES Executive problems in children and youth with epilepsy influence their ability to handle important aspects of daily life activities. The present study sought to explore factors associated with executive problems for patients with epilepsy in this age group. METHODS The cohort consisted of 97 consecutive patients at the National Centre for Epilepsy in Norway, aged 10-19 years, with focal or genetic generalized epilepsy. All underwent tests of executive functions (D-KEFS), the Behavior Rating Inventory for Executive Function (BRIEF), and screening for psychiatric symptoms, using the Strengths and Difficulties Questionnaire (SDQ). RESULTS Parent-reported cognitive executive dysfunction (BRIEF, Metacognitive Index) was the strongest independent predictor for tested executive dysfunction and vice versa. Furthermore, male gender correlated strongest with parent-reported behavioral regulation problems (BRIEF, Behavioral Regulation Index) along with borderline/pathological score on the SDQ and parent-reported cognitive executive dysfunction. CONCLUSIONS A strong association between parent-reported cognitive executive dysfunction and tested executive dysfunction was found. Male gender correlated strongest with parent-reported behavioral regulation problems. The latter was probably related to a higher frequency of symptoms associated with psychopathology among the boys than the girls. The frequency of executive deficits according to the different modes of measurement varied from 16% to 43%, suggesting that they capture different aspects of behavior under the executive umbrella.

Abstract
Antiepileptic drugs (AEDs) have many benefits but also many side effects, including aggression, agitation, and irritability, in some patients with epilepsy. This article offers a comprehensive summary of current understanding of aggressive behaviors in patients with epilepsy, including an evidence-based review of aggression during AED treatment. Aggression is seen in a minority of people with epilepsy. It is rarely seizure related but is interictal, sometimes occurring as part of complex psychiatric and behavioral comorbidities, and it is sometimes associated with AED treatment. We review the common neurotransmitter systems and brain regions implicated in both epilepsy and aggression, including the GABA, glutamate, serotonin, dopamine, and noradrenaline systems and the hippocampus, amygdala, prefrontal cortex, anterior cingulate cortex, and temporal lobes. Few controlled clinical studies have used behavioral measures to specifically examine aggression with AEDs, and most evidence comes from adverse event reporting from clinical and observational studies. A systematic approach was used to identify relevant publications, and we present a comprehensive, evidence-based summary of available data surrounding aggression-related behaviors with each of the currently available AEDs in both adults and in children/adolescents with epilepsy. A psychiatric history and history of a propensity toward aggression/anger should routinely be sought from patients, family members, and carers; its presence does not preclude the use of any specific AEDs, but those most likely to be implicated in these behaviors should be used with caution in such cases.

Zou X, Hong Z, Chen J, Zhou D. Is antiepileptic drug withdrawal status related to quality of life in seizure-free adult patients with epilepsy? Epilepsy Behav 2014; 31:129-35. [PMID: 24407247 DOI: 10.1016/j.yebeh.2013.11.028] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2013] [Revised: 11/27/2013] [Accepted: 11/29/2013] [Indexed: 10/25/2022]
Abstract
PURPOSE This study aimed to determine factors that influence the quality of life (QOL) of seizure-free adult patients with epilepsy in western China and address whether these determinants vary by antiepileptic drug (AED) withdrawal. METHODS A cross-sectional study was conducted in the epilepsy outpatient clinic of West China Hospital, Sichuan University. Patients with epilepsy who were aged at least 18years and seizure-free for at least 12months were interviewed using the Quality of Life in Epilepsy Inventory-31 (QOLIE-31); the National Hospital Seizure Severity Scale (NHS3); the Liverpool Adverse Events Profile (LAEP); the Social Support Rating Scale (SSRS); the Family Adaptation, Partnership, Growth, Affection, and Resolve (APGAR) Questionnaire; and the Scale of Knowledge and Attitudes Toward Epilepsy. Eligible patients were divided into two groups: the nonwithdrawal group and the withdrawal group. The independent-samples t-test was used to compare the QOL between the groups, and linear regression analysis was used to explain the variance of their QOL. RESULTS One hundred and eighty-seven (135 nonwithdrawal and 52 withdrawal) patients were included in the analysis. The QOLIE-31 overall score of the nonwithdrawal group was lower than that of the withdrawal group (p<0.01). The LAEP score was the strongest predictor of the QOLIE-31 overall score of all subjects, explaining 26.9% of the variance. The second strongest predictor was the SSRS score, explaining 12.9%, and the other predictors were the NHS3 score (5.2%), education level (2.3%), age (1.5%), and marriage (1.0%). Furthermore, the strongest predictors in the nonwithdrawal group were the LAEP and SSRS scores, while in the withdrawal group, the strongest predictors were stigma scores and employment. CONCLUSION Among the seizure-free adult patients with epilepsy, those with AED withdrawal experienced better QOL than those continuing AED treatment. Furthermore, the determinants of QOL varied by AED withdrawal. Individual strategies to optimize QOL should be developed based on these differences.

Abstract
The objective of this study was to evaluate the timing of medication withdrawal and other clinical factors as potential predictors of seizure relapse after antiepileptic drug (AED) withdrawal in patients with epilepsy. A total of 99 patients who were seizure free for more than 2 years were recruited from the Neurology Clinics of Nanjing Brain Hospital between 2001 and 2009, and were followed prospectively for at least 2 years or until seizure relapse. Kaplan-Meier survival analysis was used for calculating recurrence rates. Univariate and multivariate analyses for recurrence risk factors were performed using the Cox proportional hazards model. Thirteen patients were excluded due to loss of follow-up or incomplete seizure records. Epileptiform electroencephalography (EEG) abnormality within the first year after AED withdrawal (hazard ratio [HR] = 4.810, 95% confidence interval [CI] = 2.220-10.420) was found on multivariate analysis to be a predictor of seizure recurrence. Early AED withdrawal after a seizure-free period of 2-3 years did not significantly increase the risk of recurrence (HR = 0.999, 95% CI = 0.969-1.029) as compared with delayed AED withdrawal (patients who were seizure-free for more than 3 years). AED can be withdrawn in patients who have been seizure-free for more than 2 years. As epileptiform EEG abnormality within the first year after AED withdrawal predicts seizure relapse, it is necessary to perform EEG for patients during the first year after AED withdrawal.

Abstract
After a patient has initiated an antiepileptic drug (AED) and achieved a sustained period of seizure freedom, the bias towards continuing therapy indefinitely can be substantial. Studies show that the rate of seizure recurrence after AED withdrawal is about two to three times the rate in patients who continue AEDs, but there are many benefits to AED withdrawal that should be evaluated on an individualized basis. AED discontinuation may be considered in patients whose seizures have been completely controlled for a prolonged period, typically 1 to 2 years for children and 2 to 5 years for adults. For children, symptomatic epilepsy, adolescent onset, and a longer time to achieve seizure control are associated with a worse prognosis. In adults, factors such as a longer duration of epilepsy, an abnormal neurologic examination, an abnormal EEG, and certain epilepsy syndromes are known to increase the risk of recurrence. Even in patients with a favorable prognosis, however, the risk of relapse can be as high as 20% to 25%. Before withdrawing AEDs, patients should be counseled about their individual risk for relapse and the potential implications of a recurrent seizure, particularly for safety and driving.

Abstract
BACKGROUND The proper clinical context to initiate or discontinue antiepileptic drug (AED) treatment has been extensively studied over the past 40 years. Differences in study design and methodology have led to reports of seizure recurrence rates of 7% to 96% in drug initiation trials and seizure relapse rates of 12% to 67% in drug withdrawal trials. A number of different historical and clinical factors have been cited in various studies as altering seizure risk. Our objective was to review the data from large, well-conducted, prospective studies. REVIEW SUMMARY We performed an electronic search of 3 medical and scientific databases for articles on initiating or withdrawing antiepileptic medication. Our review focused primarily on articles meeting specific inclusion and exclusion criteria. We discuss the risk of seizure recurrence after a first seizure and the factors associated with an elevated risk of recurrence. The risks of treatment, including life-threatening idiosyncratic reactions and dose-related physical and cognitive side effects are reviewed. We also summarize the data on the seizure relapse risk after drug discontinuation and the factors associated with an increased relapse risk. Benefits of successful AED withdrawal are highlighted. The special considerations of treatment initiation and withdrawal in the pediatric population are explored. We propose general guidelines to assist the clinician in evaluating the risk/benefit ratio of initiating and withdrawing antiepileptic drugs. CONCLUSION Drug initiation after a first seizure decreases early seizure recurrence, but does not affect the long-term prognosis of developing epilepsy. Medication withdrawal after a period of seizure remission increases the risk of relapse, but the benefits of successful AED discontinuation may be substantial. In the end, the decision of whether to initiate treatment after a single seizure and whether to withdraw AED therapy in patients enjoying a prolonged period of seizure freedom should be made on an individual case basis, which balances the risk of seizure relapse and subsequent disability against the likely impact of medication-related physical, cognitive, and psychologic adverse effects.

Abstract
PURPOSE Most studies of quality of life (QOL) in seizure-free epilepsy patients suggest normal or near-normal function. Previous studies on QOL in well-controlled epilepsy have not investigated determinants for QOL from a database that includes a wide range of health related and epilepsy related variables, as well as demographical data, neuropsychological data, data from a comprehensive personality inventory and results from a QOL-questionnaire. Thus, the aim of this study was to analyze predictors of QOL based on such a range of variables. METHODS Adults with epilepsy on antiepileptic (AED) monotherapy and without epileptic seizures for at least 2 years (n=158) were assessed with the QOLIE-89. RESULTS The main findings were that QOL in well-controlled epilepsy patients was in the normal range and that presence of substantial health related concerns was a significant predictor of poor QOL. DISCUSSION The findings that substantial health concerns predict poor QOL may have clinical implications, as seizure-free epilepsy is a relatively benign condition, and careful information and counselling about this may alleviate health concerns and improve quality of life.

Abstract
The potential psychosocial sequelae of epilepsy are well-documented, but it cannot be assumed that trajectories for quality of life (QOL) of people with epilepsy will inevitably follow its clinical course. In this article, we draw on available literature to suggest likely QOL trajectories associated with epilepsy and the broad range of disease-, patient-, and other-focused factors that appear important in determining them. We conclude that both the likely shape and time frame for QOL trajectories associated with particular clinical scenarios can be delineated, but that their shape can be altered by a much wider range of factors than those represented as epilepsy disease progression. We identify contributory factors currently relatively unexplored and highlight implications for treatment and areas for future research.
