Epilepsia Open 2024; 9:1067-1075. [PMID: 38625683 PMCID: PMC11145617 DOI: 10.1002/epi4.12943] [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: 10/21/2023] [Revised: 04/01/2024] [Accepted: 04/03/2024] [Indexed: 04/17/2024] Open
Abstract
OBJECTIVE We studied the impact of depressive symptoms on adverse effects (AEs) in people with epilepsy (PWE) on antiseizure medication (ASM) therapy. An effect of depression on the AE burden has already been reported. We studied the correlation of various depressive symptoms with specific AEs to assess which AEs are especially prone to being confounded by particular depressive symptoms. METHODS PWE filled in a variety of questionnaires including the "Neurological Disorder Depression Inventory for Epilepsy" (NDDI-E), "Emotional Thermometers 4" (ET4) and "Liverpool Adverse Events Profile" (LAEP). Depression was defined by a NDDI-E score > 13. Depressive symptoms consisted of NDDI-E and ET4 items. Discriminant analysis identified those AEs (=LAEP items) that were most highly influenced by depression. Logistic regression analysis yielded correlations of different depressive symptoms with specific AEs. RESULTS We included 432 PWE. The strongest discriminators for depression were the LAEP items "Depression", "Nervousness/agitation," and "Tiredness". Out of all depressive symptoms "Everything I do is a struggle" most strongly correlated with total LAEP score (odds ratio [OR] = 3.1) and correlated with all but one LAEP item. Other depressive symptoms correlated to varying degrees with total LAEP and item scores. The number of ASMs, lack of seizure remission, and female gender correlated with high LAEP scores. SIGNIFICANCE To the best of our knowledge, we are the first to show that various depressive symptoms correlate with specific LAEP items. This information can be helpful for quick evaluation of whether the reporting of different LAEP items may be confounded by particular depressive symptoms. This is relevant because changes in therapy may differ depending on if AEs are confounded by depressive symptoms. Simply reporting a particular depressive symptom may give a clue to whether specific AEs are confounded by depression. Our findings confirm the importance of screening for depression in all PWE. PLAIN LANGUAGE SUMMARY In this study we measured depressive disorder and side effects caused by medication used to treat epilepsy with self-reported questionnaires in a cohort of people with epilepsy. We found depressive disorder to influence the perception of side effects that are caused by drugs used to treat epilepsy. This knowledge can help to identify if the reporting of side effects is influenced by depression. Treating depression may help to reduce side effects and may thus increase the tolerability of anti-epileptic medication. People who tolerate their medication are more likely to take it and are thus less likely to develop epileptic seizure.

Abstract
A growing number of clinical and animal studies suggest that the nucleus accumbens (NAc), especially the shell, is involved in the pathogenesis of temporal lobe epilepsy (TLE). However, the role of parvalbumin (PV) GABAergic neurons in the NAc shell involved in TLE is still unclear. In this study, we induced a spontaneous TLE model by intrahippocampal administration of kainic acid (KA), which generally induce acute seizures in first 2 h (acute phase) and then lead to spontaneous recurrent seizures after two months (chronic phase). We found that chemogenetic activation of NAc shell PV neurons could alleviate TLE seizures by reducing the number and period of focal seizures (FSs) and secondary generalized seizures (sGSs), while selective inhibition of PV exacerbated seizure activity. Ruby-virus mapping results identified that the hippocampus (ventral and dorsal) is one of the projection targets of NAc shell PV neurons. Chemogenetic activation of the NAc-Hip PV projection fibers can mitigate seizures while inhibition has no effect on seizure ictogenesis. In summary, our findings reveal that PV neurons in the NAc shell could modulate the seizures in TLE via a long-range NAc-Hip circuit. All of these results enriched the investigation between NAc and epilepsy, offering new targets for future epileptogenesis research and precision therapy.

Tomson T, Zelano J, Dang YL, Perucca P. The pharmacological treatment of epilepsy in adults. Epileptic Disord 2023; 25:649-669. [PMID: 37386690 DOI: 10.1002/epd2.20093] [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: 05/03/2023] [Revised: 06/18/2023] [Accepted: 06/24/2023] [Indexed: 07/01/2023]
Abstract
The pharmacological treatment of epilepsy entails several critical decisions that need to be based on an individual careful risk-benefit analysis. These include when to initiate treatment and with which antiseizure medication (ASM). With more than 25 ASMs on the market, physicians have opportunities to tailor the treatment to individual patients´ needs. ASM selection is primarily based on the patient's type of epilepsy and spectrum of ASM efficacy, but several other factors must be considered. These include age, sex, comorbidities, and concomitant medications to mention the most important. Individual susceptibility to adverse drug effects, ease of use, costs, and personal preferences should also be taken into account. Once an ASM has been selected, the next step is to decide on an individual target maintenance dose and a titration scheme to reach this dose. When the clinical circumstances permit, a slow titration is generally preferred since it is associated with improved tolerability. The maintenance dose is adjusted based on the clinical response aiming at the lowest effective dose. Therapeutic drug monitoring can be of value in efforts to establish the optimal dose. If the first monotherapy fails to control seizures without significant adverse effects, the next step will be to gradually switch to an alternative monotherapy, or sometimes to add another ASM. If an add-on is considered, combining ASMs with different modes of action is usually recommended. Misdiagnosis of epilepsy, non-adherence and suboptimal dosing are frequent causes of treatment failure and should be excluded before a patient is regarded as drug-resistant. Other treatment modalities, including epilepsy surgery, neuromodulation, and dietary therapies, should be considered for truly drug-resistant patients. After some years of seizure freedom, the question of ASM withdrawal often arises. Although successful in many, withdrawal is also associated with risks and the decision needs to be based on careful risk-benefit analysis.

Mesraoua B, Perucca E, Tomson T, Asadi-Pooya AA. Should antiseizure medications be withdrawn after an extended period of seizure freedom in individuals with adult-onset epilepsy? Epilepsy Behav 2023; 142:109205. [PMID: 37031583 DOI: 10.1016/j.yebeh.2023.109205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 03/15/2023] [Accepted: 03/26/2023] [Indexed: 04/11/2023]
Abstract
Unlike several epilepsies with onset in pediatric age, adult-onset epilepsies do not typically have a time course that is predictably self-remitting in the large majority of people. Still, about one-half of individuals with adult-onset epilepsy who have been seizure-free for an extended period (two years or longer) on antiseizure medications (ASMs) will remain in remission when their drug therapy is discontinued. Although a number of predictors of outcome have been identified (including specific adult-onset syndromes associated with a low probability of spontaneous remission), in most cases, the only way to establish whether the epilepsy has remitted in a given individual is to gradually withdraw ASMs. ASM withdrawal can be beneficial, particularly when the currently used treatment is not well tolerated, or could lead to adverse outcomes in the future (i.e., teratogenic effects should pregnancy occur in a female of childbearing potential). However, the risks associated with ASM withdrawal are significant. Relapse of seizures can have major adverse psychosocial consequences and also may carry a risk of morbidity and mortality. Most importantly, evidence suggests that in about 20% of individuals whose seizure relapsed following ASM withdrawal, re-institution of pharmacological therapy may not readily restore seizure control. Ultimately, management decisions should prioritize the preference of the well-informed person with epilepsy. Particularly, when adverse drug effects are a concern, options to be discussed should include not only withdrawal or continuation of the current treatment but also dose reduction or substitution with a different ASM.

Abstract
Objectives. To investigate the effectiveness, safety, and tolerability of perampanel (PER) when used as monotherapy to treat focal or generalized epilepsy in everyday clinical practice, using data from the PERMIT study. Methods. PERMIT was a pooled analysis of 44 real-world studies from 17 countries, in which people with focal and generalized epilepsy were treated with PER. This post hoc analysis included people with epilepsy (PWE) from PERMIT who were treated with PER monotherapy at baseline. Retention and effectiveness were assessed after 3, 6, and 12 months. Effectiveness assessments included ≥50% responder rate and seizure freedom rate (no seizures since at least the prior visit). Safety and tolerability were assessed by evaluating adverse events (AEs) and discontinuation due to AEs. Results. Overall, 268 PWE were treated with PER monotherapy at baseline. Retention was assessed for 168 PWE, effectiveness for 183 PWE, and safety and tolerability for 197 PWE. Retention rates were 91.1%, 87.3%, and 73.3% at 3, 6, and 12 months, respectively. At 12 months, responder rates were 84.2% overall, 82.9% in PWE with only focal-onset seizures at baseline, and 88.0% in those with only generalized-onset seizures at baseline; corresponding freedom rates were 62.9%, 57.7%, and 80.0%, respectively. AEs were reported for 45.2% of PWE. The most frequently reported AEs (≥5% of PWE) were dizziness/vertigo (16.8%), irritability (11.2%), somnolence (9.1%), and depression (6.6%). Over 12 months, 13.7% discontinued due to AEs. Conclusions. PER was effective when used as monotherapy in clinical practice, particularly in those with generalized-onset seizures, and was generally well tolerated.

Abstract
OBJECTIVES To develop and validate a Lithuanian version of the Liverpool Adverse Events Profile (LT-LAEP), and to evaluate the main demographic, clinical, and pharmacological determinants of its score. MATERIALS AND METHODS We developed the LT-LAEP and examined its psychometric properties. People with epilepsy (PWE) were asked to fill in the LT-LAEP, the Generalized Anxiety Disorder scale-7 (GAD-7), the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), and a questionnaire addressing key demographic and clinical information. Antiseizure medicine (ASM) burden was expressed as a number of ASM and total drug load. Multiple linear regression analysis was used to determine the influence of various variables on LAEP results. RESULTS The data of 157 participants with the established diagnosis of epilepsy and stable ASM regimen were included in the final analysis. The mean LT-LAEP score was 48.72 ± 13.65. High internal consistency (Cronbach's α = 0.912) and test-retest reliability (ICC = 0.801) were demonstrated. The most common adverse effects (AEs) were tiredness (24.8%) and memory problems (23.6%). Lithuanian version of the Liverpool Adverse Events Profile score significantly correlated with NDDI-E (r = 0.635, p < 0.001) and GAD-7 (r = 0.640, p < 0.001) scores. The correlation between LT-LAEP score and total drug load was weak (r = 0.243, p = 0.002). The significant predictors of higher LT-LAEP score were female sex (β = -4.768, p = 0.003), higher seizure frequency (β = 4.757, p < 0.001), and higher NDDI-E (β = 1.457, p < 0.001) and GAD-7 scores (β = 0.610, p = 0.007) (F(4,152) = 43.975, R2 = 0.536, p < 0.001). CONCLUSIONS The LT-LAEP is a reliable and valid instrument for the evaluation of the AEs of ASM. A higher score of LT-LAEP is predicted by female sex, seizure frequency, and anxiety and depression levels rather than total drug load.

Abstract
First seizures are often perceived as devastating events by patients and their families due to the fear of having a life-long disease. One in 10 people experiences one or more seizures during their lifetime, while 1 in 26 people develops epilepsy. Acute symptomatic seizures are often related to a provoking factor or an acute brain insult and typically do not recur. Careful history and clinical examination should guide clinicians' management plans. Electroencephalography and brain imaging, preferably with epilepsy-specific magnetic resonance imaging, may help characterize both etiology and risk of seizure recurrence. Antiepileptic drugs should be initiated in patients with newly diagnosed epilepsy. In patients without an epilepsy diagnosis, the decision to prescribe drugs depends on individual risk factors for seizure recurrence and possible complications from seizures, which should be discussed with the patient. Counseling about driving and lifestyle modifications should be provided early, often at the first seizure encounter.

Abstract
Background The number of patients with epilepsy receiving perampanel or lacosamide as an add-on treatment following levetiracetam treatment has increased. Although levetiracetam causes psychiatric disorders, it is unclear whether they occur with the combined use of these antiepileptic drugs. Objective To determine the frequency of psychiatric disorders in patients received lacosamide or perampanel in combination with levetiracetam. Setting A single-center retrospective cohort study. Method Patients who received levetiracetam + lacosamide or levetiracetam + perampanel were selected. Medical records from the start of combination therapy contained characteristics of patients and the incidence of psychiatric disorders. Main outcome measure The frequency of psychiatric disorders, the time to onset, dose reduction or discontinuation following psychiatric disorders, and the clinical course following disorder onset. Results Forty-four patients used levetiracetam + lacosamide and 50 used levetiracetam + perampanel. The incidence of psychiatric disorders was significantly lower (p < 0.001) with levetiracetam + lacosamide (6.8%) than with levetiracetam + perampanel (44%). The incidence of affect lability was significantly higher with levetiracetam + perampanel than with levetiracetam + lacosamide (p = 0.018). The time to the onset of psychiatric disorders was within 1 month of dose initiation or increase in one case (33.3%) with levetiracetam + lacosamide and 16 cases (72.7%) with levetiracetam + perampanel. There was no significant difference in clinical characteristics and antiepileptic drug dosages owing to the presence or absence of psychiatric disorders. Conclusion As the frequency of psychiatric disorders was higher with levetiracetam + perampanel therapy, levetiracetam + lacosamide may be preferable. These disorders tended to develop within 1 month of therapy and were not dose-dependent. Antiepileptic drugs should be cautiously prescribed to avoid psychiatric disorders.

Abstract
Objective: This study aimed to determine the efficacy and clinical factors related to the pharmacodynamics of single or combination therapies of valproic acid (VPA), carbamazepine (CBZ), and oxcarbazepine (OXC), three commonly used anti-epileptic drugs (AEDs) in China. Methods: The study evaluated the records of 2027 outpatients in a Changsha hospital, located in China, from December 23, 2015 to October 28, 2019. The baseline seizure frequency was assessed during the first visit. AED efficacy was determined based on the reduction in seizures from baseline at the subsequent visits. Multivariable ordinal regression analysis was used to determine the association between the clinical factors (demographic characteristics, clinical features, and medication situation) and AED efficacy. For validation, the clinical efficacies of AEDs were compared as both single agents and in combinations. Differences in adverse effect (AEs) categories were analyzed by Chi-square between AED groups. Results: Records of patients receiving VPA, CBZ, and OXC were evaluated. Serum concentrations of VPA and CBZ is significantly correlated with efficacy (OR 1.030 [1.024–1.037], p < 0 0.0001; OR 1.250 [1.146–1.63], p < 0.0001, respectively) and OXC efficacy correlated to the serum concentration of the metabolite 10,11-dihydro-10-hydroxy-carbazepine (monohydroxy derivative, MHD) serum concentrations (OR 1.060 [1.031–1.089], p < 0.0001). Significant differences existed between females and males in VPA efficacy (OR 1.318 [1.033–1.682], p = 0.027). After validation, VPA, in combination with OXC (OR 1.93 [1.38–2.70], p<0.001), or with VGB (Vigabatrin) (OR 2.36 [1.38–2.70], p = 0.002), showed significantly better efficacy than as a single agent. OXC efficacy was also affected by the duration of epilepsy (OR 0.965 [0.946–0.984], p < 0.001). Additionally, the efficacies of OXC and VPA were also affected by the seizure type. Seizure reduction improved significantly with an increasing number of pharmacists’ educations in the first three visits period. There were no differences in AEs incidence among these 3 AEDs except for Psychiatric (0.02) and nervous system disorders (0.0001). Conclusion: Serum concentrations of VPA and CBZ may positively affect their efficacies, while OXC efficacies are correlated to MHD serum concentrations. The efficacy of VPA was higher in females compared to males. VPA-OXC and VPA-VGB combinations had higher efficacies compared to monotherapy. Besides, OXC efficacy is probably reducing by the duration of epilepsy. Additionally, VPA efficacy for focal or generalized seizures is superior to mixed-type seizures. OXC was more effective for focal seizures compared to mixed-type ones. Education provided by pharmacists improved the seizures to some extent, and there were no significant differences between most categories of adverse effects for the investigated AEDs.

Abstract
Importance Tolerability is a key determinant of the effectiveness of epilepsy treatment. It is important to evaluate whether the overall tolerability has improved. Objective To identify factors associated with poor tolerability of antiseizure medications (ASMs) and examine temporal changes in tolerability. Design, Setting, and Participants This was a longitudinal cohort study at a specialist clinic in Glasgow, Scotland. Patients with newly diagnosed and treated epilepsy between July 1982 and October 2012 were included from 2282 eligible individuals. They were followed up until April 2016 or death. Data analysis was completed in August 2019. Exposures Antiseizure medications. Main Outcomes and Measures Univariable and multivariable survival analyses were performed to examine associations between potential risk factors and development of intolerable adverse effects (AEs). Intolerable AE rates of the ASMs as the initial monotherapy were compared between 3 epochs (July 1982-June 1992, July 1992-June 2002, and July 2002-April 2016). Results Of 1795 patients, 969 (54.0%) were male, and the median (interquartile range) age was 33 (21-50) years. A total of 3241 ASMs were prescribed during the period, of which 504 (15.6%) were discontinued within 6 months owing to intolerable AEs. Children younger than 18 years had lower intolerable AE rates than adults (vs aged 18-64 years: adjusted hazard ratio [aHR], 1.58; 95% CI, 1.07-2.32; vs aged ≥65 years: aHR, 1.90; 95% CI, 1.19-3.02) while female individuals (aHR, 1.60; 95% CI, 1.30-1.96) and those who had more than 5 pretreatment seizures (aHR, 1.24; 95% CI, 1.03-1.49) were associated with having higher risk. For each ASM trial, the risk of intolerable AEs increased with the number of previous drug withdrawals due to AEs (aHR, 1.18; 95% CI, 1.09-1.28) and the number of concomitant ASMs (aHR, 1.31; 95% CI, 1.04-1.64). The proportion of second-generation ASMs prescribed as the initial monotherapy increased from 22.3% (33 of 148) in the first epoch to 68.7% (645 of 939) in the last (P < .001). Although differences in intolerable AE rates and types of AEs were found between the ASMs, there was no difference in the overall intolerable AEs rates to the initial monotherapy across the 3 epochs (first: 10.1% [15 of 148]; second: 13.8% [98 of 708]; third: 14.0% [131 of 939]; P = .41). Conclusions and Relevance In this cohort study, the increased use of the second-generation ASMs had not improved overall treatment tolerability. Greater effort to improve tolerability in ASM development is needed.

Heidemann J, Schmitz B, Kostev K. Association between antiseizure medication use and risk of urinary tract infection: A case-control study. Epilepsy Behav 2021; 115:107502. [PMID: 33323337 DOI: 10.1016/j.yebeh.2020.107502] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 08/31/2020] [Accepted: 09/11/2020] [Indexed: 12/23/2022]
Abstract
AIM The aim of this study was to analyze the association between antiseizure medication (ASM) and the risk of urinary tract infections (UTI) in patients with epilepsy treated in general practices in Germany. METHODS This study includes a total of 2201 patients (mean age: 61.4) whose first documented UTI diagnosis occurred between January 2015 and December 2019 (index date) and who were prescribed at least one ASM in 1198 general practices in Germany within one year prior to the index date. Based on a case-control design, the association between predefined criteria and UTI was investigated by matching (1:1) controls without UTI to cases with UTI by sex, age, and codiagnoses. Logistic regression models were used to analyze the association between ASM use and UTI risk. RESULTS In the first regression model, phenytoin (PHT), primidone, carbamazepine (CBZ), and valproate (VPA) were associated with an increased risk of UTI. In the second model, these associations were confirmed with effects per prescription for PHT, primidone, CBZ, and VPA use. Additionally, the effect per prescription was significant for oxcarbazepine (OXC), topiramate, and gabapentin. CONCLUSION The study found that PHT, primidone, CBZ, and VPA in particular are associated with an increased risk of infections of the urinary tract. Oxcarbazepine, topiramate, and gabapentin are also associated with increased risk of UTI, albeit to a less significant extent. In general, the immunological and hematological side effects of these molecules may play an important role in the development of UTI under anticonvulsant therapy.

Sex Differences in the Risk of Cutaneous Adverse Drug Reactions Induced by Antiseizure Medications: A Systematic Review and Meta-analysis. CNS Drugs 2021; 35:161-176. [PMID: 33580477 DOI: 10.1007/s40263-021-00794-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 01/11/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND Cutaneous adverse drug reactions (cADRs) are one of the most common, severe, and life-threatening types of adverse reactions following treatment with antiseizure medications (ASMs). Some studies have reported a higher incidence of ASM-induced cADRs in females than in males. OBJECTIVE This study sought to perform a systematic review, meta-analysis, and meta-regression to compare the ASM cADR risks between females and males. METHODS We searched the literature using three databases (EMBASE, PubMed, and Web of Science) between October 1998 and November 2018, later updated to October 2019. Studies were included in the meta-analysis if they met the following criteria: (1) observational studies that estimated the incidence of cADRs related to ASMs; (2) provided the risk or odds ratio (OR) for cADRs among female and male patients exposed to ASMs; and (3) provided information on patients' characteristics. We assessed the impact of study characteristics, publication bias, and measures to reduce bias, and performed a DerSimonian and Laird random effects meta-analysis. RESULTS We included 28 studies in this review. Of these, seven studies were eligible for inclusion in the meta-analysis, involving a total of 223,209 patients. Overall, females were more likely to develop cADRs to ASMs than males (OR 1.76, 95% confidence interval [CI] 1.55-1.99). The largest differences were observed in patients prescribed lamotrigine (OR 2.17, 95% CI 1.53-3.08, p < 0.001) and carbamazepine (OR 1.63, 95% CI 1.02-2.60, p = 0.042). Also, the OR trended higher for phenytoin (OR 2.46, 95% CI 0.79-7.65, p = 0.12), followed by oxcarbazepine (OR 1.91, 95% CI 0.75-4.85, p = 0.18) and sodium valproate (OR 0.60, 95% CI 0.12-2.99, p = 0.53), but the difference did not reach statistical significance. In the remaining 21 studies, 13 reported numerically higher risk of cADRs among females compared to male patients, and in five of these, the difference was statistically significant. CONCLUSION Our findings confirmed that females are more susceptible to cADRs induced by ASMs than males. More research is needed to understand the pathophysiological mechanisms for this difference.

The management of epilepsy in clinical practice: Do the timing and severity of the disease influence the priorities of patients and the caring physicians? Data from the EPINEEDS study. Epilepsy Behav 2021; 114:107201. [PMID: 32739237 DOI: 10.1016/j.yebeh.2020.107201] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Accepted: 05/25/2020] [Indexed: 02/07/2023]
Abstract
OBJECTIVE The objective of this study was to assess the priorities of patients with epilepsy and their caring physicians with reference to the timing and severity of the disease. METHODS This is a national survey in which patients with epilepsy followed in 21 Italian epilepsy centers, and their caring physicians were asked to fill anonymous questionnaires to collect data on different aspects of the disease and their needs and priorities in its management. The collected information included demographics, clinical profile and diagnosis, treatment and outcome of epilepsy. The questions were designed to understand the expectations of the patients and their caring physicians and verify the degree of concordance between patient and doctor. The study population was divided in six prognostic categories: (1) Newly diagnosed epilepsy; (2) Absence of seizures for at least 2 years; (3) Absence of seizures for at least 1 year or occasional seizures; (4) Nondrug-resistant recurrent seizures; (5) drug-resistant seizures; (6) surgical candidate. RESULTS Of the 787 patients enrolled, 432 were women and 355 men aged 15 to 88 years (median 41 years). Disease duration ranged from 6 months to 75 years. The sample included 53 patients with newly diagnosed epilepsy, 283 without seizures for at least 2 years, 162 seizure-free for at least 1 year or with occasional seizures, 123 with nondrug-resistant recurrent seizures, 128 with drug-resistant seizures, and 38 surgical candidates. Significant differences were found between patients and physicians in terms of priorities and needs with reference to the management of the disease. While physicians tend to prioritize the information on the diagnosis and treatment of epilepsy depending on timing and severity, patients focus on the search of the cause, the side effects of drugs, and the effects of any new treatment on the control of seizures regardless of the prognostic category. In addition, physicians tend to undervalue the communication of specific information, like the risk of sudden unexpected death in epilepsy (SUDEP) or the existence of lay associations, which might be of special interest for selected categories of patients. SIGNIFICANCE Differences between patients with epilepsy and their caring physicians in terms of needs and priorities and suboptimal communication call for the implementation of programs aimed at addressing the factors deemed most relevant by patients and caregivers for the management of the disease.

Abstract
OBJECTIVE The aim of this systematic review and meta-analysis was to provide an estimate of the prevalence of anxiety and depressive disorders in youth with epilepsy (YWE). It also aimed to calculate the overall magnitude of observed differences in anxiety and depressive symptoms reported by YWE compared with healthy controls and investigate whether any factors moderated anxiety and depression outcomes in YWE. METHODS Following prospective registration, electronic databases were searched up until October 2018. Studies were included if they reported on the rate of anxiety or depression in samples of YWE, and/or if they used valid measures of anxious or depressive symptomatology in YWE compared with a healthy control sample. RESULTS Twenty-three studies met inclusion criteria. The overall pooled prevalence of anxiety disorders in YWE was 18.9% (95% confidence interval [CI] 12.0%-28.5%), and for depression the pooled prevalence was 13.5% (95% CI 8.8%-20.2%). In samples of YWE compared with healthy controls, significantly higher anxiety (d = 0.57, 95% CI 0.32-0.83, p < .000) and depressive (d = 0.42, 95% CI 0.16-0.68, p < .000) symptomatology was reported. CONCLUSIONS YWE report anxiety and depressive disorders and symptoms to a significantly higher degree than youth without epilepsy. There is also evidence that certain anxiety disorders (e.g. generalized anxiety disorder, separation anxiety disorder) are particularly elevated, perhaps reflecting the unique impact of epilepsy on youth psychopathology. Research is needed to understand the risk factors associated with anxiety and depressive disorders in epilepsy, and better understand how these symptoms change across development.

Abstract
OBJECTIVE The aim of the present study was to explore the factors related to the severity of the adverse effects of antiepileptic drugs (AEDs), experienced by patients with epilepsy. MATERIALS AND METHODS A case study was conducted in adult patients with epilepsy and followed up at the Epilepsy Outpatients of the University Hospital of Ioannina in Northwest Greece. The Adverse Event Profile (AEP) questionnaire for AEDs adverse effects assessment, the Defense style questionnaire (DSQ-88) and the Patient Health Questionnaire (PHQ-9) for depression' severity evaluation were used to estimate the severity of adverse effects, the defense style, and the depressive symptoms, respectively. RESULTS Sixty-three patients with epilepsy (M/F:28/35), with a mean age of 37.6 ± 13.41, were recruited in the study. The univariate analysis showed that both the Maladaptive style of defense and the PHQ-9 score were significantly associated with the AEP score. After multivariate regression analysis female gender, the load of AEDs, the PHQ-9 score, and the Adaptive defense style remained significant coefficients. CONCLUSION There are also nonpharmacological factors that may contribute to the severity of the adverse effects of AEDs, experienced by the patients with epilepsy.

Abstract
Neuroprotective and antiepileptogenic therapies have been extensively investigated for epilepsy prevention and treatment. This review gives an overview of the promising contribution of the ketogenic diet, a complementary treatment, on the intestinal microbiota to reduce seizure susceptibility. Next, the relevance of physical exercise is extensively addressed as a complementary therapy to reduce seizure susceptibility, and thereby impact beneficially on the epilepsy condition. In this context, particular attention is given to the potential risks and benefits of physical exercise, possible precipitant factors related to exercise and proposed mechanisms by which exercise can reduce seizures, and its antiepileptogenic effects. Finally, this review points to emerging evidence of exercise reducing comorbidities from epilepsy and improving the quality of life of people with epilepsy. Based on evidence from current literature, physical or sport activities represent a potential non-pharmacological intervention that can be integrated with conventional therapy for epilepsy.

Abstract
Drug side effects have become an important indicator for evaluating the safety of drugs. There are two main factors in the frequent occurrence of drug safety problems; on the one hand, the clinical understanding of drug side effects is insufficient, leading to frequent adverse drug reactions, while on the other hand, due to the long-term period and complexity of clinical trials, side effects of approved drugs on the market cannot be reported in a timely manner. Therefore, many researchers have focused on developing methods to identify drug side effects. In this review, we summarize the methods of identifying drug side effects and common databases in this field. We classified methods of identifying side effects into four categories: biological experimental, machine learning, text mining and network methods. We point out the key points of each kind of method. In addition, we also explain the advantages and disadvantages of each method. Finally, we propose future research directions.

Abstract
BACKGROUND Patients with epilepsy (PwE) have an increased risk of active and lifetime depression. Two in 10 patients experience depression. Lack of trained psychiatric staff in low- and middle-income countries (LMIC) creates a need for screening tools that enable detection of depression in PwE. We describe the translation, validity and reliability assessment of the Patient Health Questionnaire-9 (PHQ-9) as a screening tool for depression among PwE in Rwanda. METHOD PHQ-9 was translated to Kinyarwanda using translation-back translation and validated by a discussion group. For validation, PwE of ≥15 years of age were administered the PHQ-9 and Hamilton Depression Rating Scale (HDRS) by trained psychiatry staff at Visit 1. A random sample of 20% repeated PHQ-9 and HDRS after 14 days to assess temporal stability and intra-rater reliability. Internal structure, reliability and external validity were assessed using confirmatory factor analysis, reliability coefficients and HDRS-correlation, respectively. Maximal Youden's index was considered for cut-offs. RESULTS Four hundred and thirty-four PwE, mean age 30.5 years (SD ±13.3), were included of whom 33.6%, 37.9%, 13.4%, and 15.1% had no, mild, moderate and severe depression, respectively. PHQ-9 performed well on a one-factor model (unidimensional model), with factor loadings of 0.63-0.86. Reliability coefficients above 0.80 indicated strong internal consistency. Good temporal stability was observed (0.79 [95% CI: 0.68-0.87]). A strong correlation (R = 0.66, p = 0.01) between PHQ-9 and HDRS summed scores demonstrated robust external validity. The optimal cut-off for the PHQ-9 was similar (≥5) for mild and moderate depression and ≥7 for severe depression. CONCLUSION PHQ-9 validation in Kinyarwanda creates the capacity to screen PwE in Rwanda at scores of ≥5 for mild or moderate and ≥7 for severe depression. The availability of validated tools for screening and diagnosis for depression is a forward step for holistic care in a resource-limited environment.

Abstract
OBJECTIVE This study aimed to explore the quality of life (QoL) of adult patients with epilepsy (PwE) in Australia and its relationship with comorbidities and adverse events (AEs) from antiepileptic drugs (AEDs). METHODS Cross-sectional surveys were completed by PwE, or carer proxies, recruited via the online pharmacy application MedAdvisor and Australian PwE Facebook groups from May to August 2018. Data were collected on demographics, epilepsy severity and management, AEs, comorbidities, and QoL (using the Patient-Weighted Quality of Life in Epilepsy Inventory [QOLIE-10-P] total score). Two linear regression models were constructed to explore associations between AEs or comorbidities and QOLIE-10-P score, with possible confounders determined using stepwise selection. RESULTS Nine hundred and seventy-eight of 1267 responses were eligible (mean age of respondents: 44.5 years, 64% female, 52% employed). Recent AED use was reported by 97%; 47% were on AED monotherapy, 35% had ≤2 lifetime AEDs, and 55% were seizure-free for >1 year. After stepwise selection, control variables included in both models were time since diagnosis, employment status, seizure frequency, number of currently prescribed AEDs, and number of general practitioner (GP) visits per year. In the model for comorbidities, "psychiatric disorders" was associated with the largest QOLIE-10-P score decrease (-23.14, p < 0.001). In the model for AEs, which additionally controlled for depression and anxiety disorder, self-reported "memory problems" was associated with the largest decrease in QOLIE-10-P score (-14.27, p < 0.001). CONCLUSIONS In this survey of Australian PwE, many of whom had relatively well-controlled epilepsy, psychiatric and self-reported memory problems were common and associated with the greatest detrimental impact on QoL. Further research is needed to better understand the underlying causes of impaired QoL and thereby improve its management.

Abstract
OBJECTIVES To describe the long-term prognosis of epilepsy and prognostic patterns in a large cohort of newly diagnosed patients and identify prognostic factors. METHODS Study participants were 13 Italian epilepsy centres with accessible records dating back to 2005 or earlier, complete data on seizure outcome and treatments, precise epilepsy diagnosis, and follow-up of at least 10 years. Records were examined by trained neurology residents for demographics, seizure characteristics, neurological signs, psychiatric comorbidity, first electroencephalogram (EEG) and MRI/CT, epilepsy type and aetiology, antiepileptic drugs (AEDs), and 1-year, 2-year, 5-year and 10-year seizure remissions. Five predefined prognostic patterns were identified: early remission, late remission, relapsing-remitting course, worsening course and no remission. Prognostic factors were assessed using multinomial logistic regression models. RESULTS 1006 children and adults were followed for 17 892 person-years (median 16 years; range 10-57). During follow-up, 923 patients (91.7%) experienced 1-year remission. 2-year, 5-year and 10-year remissions were present in 89.5%, 77.1% and 44.4% of cases. 5-year remission was associated with one to two seizures at diagnosis, generalised epilepsy, no psychiatric comorbidity, and treatment with one or two AEDs during follow-up. 10-year remission was associated with one or two AEDs. The most common prognostic pattern was relapsing-remitting (52.2%), followed by early remission (24.5%). 8.3% of cases experienced no remission. Predictors of a relapsing-remitting course were <6 seizures at diagnosis, (presumed) genetic aetiology and no psychiatric comorbidity. CONCLUSIONS Few seizures at diagnosis, generalised epilepsy and no psychiatric comorbidity predict early or late seizure freedom in epilepsy. Achieving remission at any time after the diagnosis does not exclude further relapses.

Kalilani L, Friesen D, Murray P. Treatment patterns in patients with a new diagnosis of epilepsy and psychiatric comorbidities. Epilepsy Behav 2019; 99:106405. [PMID: 31487669 DOI: 10.1016/j.yebeh.2019.07.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Revised: 07/02/2019] [Accepted: 07/03/2019] [Indexed: 10/26/2022]
Abstract
OBJECTIVE The objective of this study was to describe antiepileptic drug (AED) treatment patterns in patients with epilepsy, with and without psychiatric comorbidities. METHODS This was a retrospective claims-based cohort study using Truven Health MarketScan databases (Commercial and supplemental Medicare, calendar years 2012-2017; Medicaid, 2012-2016). Persons met epilepsy diagnostic criteria, had an index date (first epilepsy diagnosis) with a preceding 2-year baseline (<1 year for persons of 1 to <2 years of age; none for persons <1 year), and continuous medical and pharmacy enrolment without epilepsy/seizure diagnosis or AED prescription during baseline. Based on presence/absence of psychiatric diagnosis codes in the baseline period, persons were classified into two cohorts: with or without psychiatric comorbidities. Outcomes included percentage of treated persons (AED prescription), type, duration, and outcome of first-line AED treatment. RESULTS There were 18,062 persons in each cohort with and without psychiatric comorbidities, matched by age, sex, and insurance type, who met selection (or inclusion) criteria. More patients with psychiatric comorbidities were prescribed an AED after diagnosis (57.6% vs. 52.8%), and had at least two AEDs prescribed during follow-up (16.7% vs. 11.4%) than patients without psychiatric comorbidities. Most patients with and without psychiatric comorbidities prescribed AED monotherapy as first-line treatment (73.0% vs. 78.7%). Levetiracetam was the most common AED prescribed less frequently in patients with than without psychiatric comorbidities (40.8% vs. 56.7%). More patients with psychiatric comorbidities changed first-line AED treatment than patients without psychiatric comorbidities. CONCLUSION The presence of psychiatric comorbidities may impact treatment decisions in newly diagnosed persons with epilepsy to optimize patient outcomes.

Abstract
OBJECTIVE The objective of the study was to investigate the relationship between sociodemographic, seizure-related, behavioral health, and antiepileptic drug (AED) adverse effect variables. The aim of this study was to examine whether there were significant differences on AED adverse effects between youth with normative and subclinical/clinical depressive and/or anxiety symptoms. METHODS As part of a larger multisite validation study, 231 youth age 5 to 18 years diagnosed with epilepsy and their caregivers were recruited to participate for the current study. Youth ages 8 and older and caregivers of all youth completed the Behavior Assessment System for Children-2 (BASC-2). Caregivers also completed the Pediatric Epilepsy Side Effects Questionnaire (PESQ) and a Background Questionnaire. Medical chart review provided information regarding epilepsy diagnosis and treatment. RESULTS No differences were observed in the mean scores on AED adverse effects between the group with subclinical/clinical BASC-2 Depressive symptoms and those with average/low depressive symptoms. In contrast, the proportion of youth with subclinical/clinical versus average/low depressive symptoms via caregiver report was significantly different for the cognitive, behavioral, general neurological, and total scale of the PESQ. There was also a larger proportion of youth with self-reported subclinical/clinical depressive symptoms who experienced general neurological adverse effects compared with youth with average/low depressive symptoms who experienced general neurological adverse effects. Findings were consistent for anxiety symptoms. SIGNIFICANCE Identifying potentially modifiable behavioral health symptoms that exacerbate the expression of AED adverse effects could provide alternative solutions for improved AED tolerability to achieve optimum treatment outcomes.

Abstract
OBJECTIVES For most people with epilepsy (PWE), problems that are not directly related to seizures may constitute major challenges in everyday life. The purpose of this study was to determine the extent of these challenges and any risk factors for their occurrence among PWE in Norway, based on the patients' own perspective. MATERIALS AND METHODS We used a web-based survey to ask PWE visiting the homepage of the Norwegian Epilepsy Association about different everyday challenges. A link to the survey was accessible via the members' homepage for a 4-month period during 2017. RESULTS One thousand one hundred eighty-two PWE responded to the questionnaire. Although more than 40% of the cohort reported that they had been seizure free for at least 1 year, the majority reported that tiredness (71%), memory problems (70%), concentration problems (68%), headache or vertigo (51%), and feeling depressed (59%) continued to represent challenges. In addition, fear of being alone, sexual problems or difficulties in social settings were reported by about one-third of the patients. Reporting having these challenges was significantly associated with female gender, polytherapy, experiencing seizures during the previous 12 months and feeling blue or depressed. CONCLUSIONS The results of this study, reflecting a self-selected Norwegian population, provide insights into the challenges not directly associated with seizures that impact on the quality of life of PWE. The impacts of such challenges may be underestimated as components of the entire burden of epilepsy.

Abstract
BACKGROUND Pre-treatment factors that increase smokers' risk of experiencing neuropsychiatric adverse events (NPSAEs) when quitting smoking are unknown. OBJECTIVE To identify baseline smoker characteristics beyond the history of mental illness that predict which participants were more likely to experience moderate to severe NPSAEs in EAGLES. DESIGN A prospective correlational cohort study in the context of a multinational, multicenter, double-blind, randomized trial. PARTICIPANTS Smokers without (N = 3984; NPC)/with (N = 4050; PC) histories of, or current clinically stable, psychiatric disorders including mood (N = 2882; 71%), anxiety (N = 782; 19%), and psychotic (N = 386; 10%) disorders. INTERVENTIONS Bupropion, 150 mg twice daily, or varenicline, 1 mg twice daily, versus active control (nicotine patch, 21 mg/day with taper) and placebo for 12 weeks with 12-week non-treatment follow-up. MAIN MEASURES Primary safety outcome was the incidence of a composite measure of moderate/severe NPSAEs. Associations among baseline demographic/clinical characteristics and the primary safety endpoint were analyzed post hoc via generalized linear regression. KEY RESULTS The incidence of moderate to severe NPSAEs was higher among smokers in the PC (238/4050; 5.9%) than in the NPC (84/3984; 2.1%). Three baseline characteristics predicted increased risk for experiencing clinically significant NPSAEs when quitting regardless of carrying a psychiatric diagnosis: current symptoms of anxiety (for every ~ 4-unit increase in HADS anxiety score, the absolute risk of occurrence of the NPSAE endpoint increased by 1% in both PC and NPC); prior history of suicidal ideation and/or behavior (PC, 4.4% increase; P = 0.001; NPC, 4.1% increase; P = 0.02), and being of White race (versus Black: PC, 2.9% ± 0.9 [SE] increase; P = 0.002; and NPC, 3.4% ± 0.8 [SE] increase; P = 0.001). Among smokers with psychiatric disorders, younger age, female sex, history of substance use disorders, and proxy measures of nicotine dependence or psychiatric illness severity also predicted greater risk. There were no significant interactions between these characteristics and treatment. Smokers with unstable psychiatric disorders or with current, active substance abuse were excluded from the study. CONCLUSIONS Irrespective of cessation pharmacotherapy use, smokers attempting to quit were more likely to experience moderate to severe NPSAEs if they reported current anxiety or prior suicidal ideation at baseline and were White. In smokers with a psychiatric history, female sex, younger age, and greater severity of nicotine dependence were also predictive. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01456936.

Abstract
INTRODUCTION Epilepsy is a serious chronic neurological disorder manifested by an enduring symptomatic predisposition to seizures. Newly diagnosed individuals face increased morbidity, mortality, and socioeconomic costs. Anti-epileptic drug therapy is the treatment usually prescribed, which has efficacy in seizure control and mitigating long-term mortality. AREAS COVERED Safety of anti-epileptic drug therapy in adults with a focus in newly diagnosed patients. Areas covered include the most commonly experienced adverse drug effects, as well as those with the highest impacts on drug tolerability, quality of life, morbidity and mortality. Evidence was also reviewed to identify clinical strategies to improve the safety of anti-epileptic drug therapy. EXPERT OPINION Anti-epileptic drugs (AEDs) are mostly effective and well tolerated. However, a lack of standardised reporting of adverse drug effects in trials and in clinical practice provides an obstacle for evaluation of which adverse drug effects need to be prioritised in management. Improvement in the reporting of cognitive and other effects, as well as improved precision medicine and pharmacogenomics to target the incidence of high-mortality idiosyncratic reactions, will help to reduce the harm of AEDs in people newly diagnosed with epilepsy.

Abstract
PURPOSE Suicidality including suicidal ideation and attempt has been a critical issue in people with epilepsy, especially in people with drug-resistant epilepsy (PWDRE). Clinicians commonly ask about adverse effects of antiepileptic drugs (AEDs) using something like the Liverpool Adverse Events Profile (LAEP) at epilepsy clinics, but suicide is usually not of interest. A high risk of suicidality can increase mortality by committing suicide in PWDRE. This study aimed to investigate whether clinicians can discern a high risk of suicidality in PWDRE by referring to the LAEP. METHODS We recruited PWDRE, aged from 19 to 68. They completed the 21-item LAEP, the suicidality module of the Mini International Neuropsychiatric Interview, and the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E). Through receiver operating characteristic curve analysis, we tested the usefulness of LAEP to detect a high risk of suicide. By this, we determined each cutoff point of the total LAEP score and the number of severe LAEP items, for detecting the risk. RESULTS A hundred forty-four PWDRE participated in this study. Among them, 36 PWDRE (25.0%) had a high risk of suicidality. Either >45 of the total LAEP score or >8 of the number of severe LAEP items was a suggested optimal cutoff point for discerning the high risk of suicidality. LAEP had a correlation with the suicidality item of the NDDI-E. CONCLUSION The LAEP may inform a high risk of suicidality in PWDRE. Referring to this, clinicians can discern suicidal problems in their epilepsy clinics.

Abstract
Background and Purpose The Liverpool adverse events profile (LAEP) is useful for detecting and monitoring the adverse effects of antiepileptic drugs (AEDs) and contains items related to symptoms of depression or anxiety. This study evaluated the usefulness of the LAEP for detecting comorbid depression or anxiety disorder in people with epilepsy (PWE). Methods PWE, aged from 18 to 70 years and who took AEDs for at least 1 year, were included. They completed the Korean version of the LAEP (K-LAEP) to detect the adverse effects of AEDs and the mini international neuropsychiatric interview-plus version 5.0.0 (MINI) to identify major depressive disorder (MDD) and generalized anxiety disorder (GAD). We validated the K-LAEP as a screening tool for coexisting MDD or GAD in PWE. Receiver operating character (ROC) curve analyses were used to measure the appropriateness of cutoff scores for the total and item K-LAEP scores for detecting MDD or GAD. Results The study enrolled 150 PWE. According to the MINI, 30 PWE (20.0%) had MDD and 26 (17.3%) had GAD. Cronbach's α coefficient of the K-LAEP was 0.939. For the total K-LAEP score, cutoff scores of 40 and 43 could detect MDD and GAD, respectively. For the K-LAEP item score, a cutoff of five could detect MDD or GAD. Conclusions The K-LAEP is a valid screening tool for detecting MDD and GAD in PWE. A high LAEP score suggests comorbid psychiatric disorders, which need further specific evaluation.

Abstract
Epilepsy affects all age groups and is one of the most common and most disabling neurological disorders. The accurate diagnosis of seizures is essential as some patients will be misdiagnosed with epilepsy, whereas others will receive an incorrect diagnosis. Indeed, errors in diagnosis are common, and many patients fail to receive the correct treatment, which often has severe consequences. Although many patients have seizure control using a single medication, others require multiple medications, resective surgery, neuromodulation devices or dietary therapies. In addition, one-third of patients will continue to have uncontrolled seizures. Epilepsy can substantially impair quality of life owing to seizures, comorbid mood and psychiatric disorders, cognitive deficits and adverse effects of medications. In addition, seizures can be fatal owing to direct effects on autonomic and arousal functions or owing to indirect effects such as drowning and other accidents. Deciphering the pathophysiology of epilepsy has advanced the understanding of the cellular and molecular events initiated by pathogenetic insults that transform normal circuits into epileptic circuits (epileptogenesis) and the mechanisms that generate seizures (ictogenesis). The discovery of >500 genes associated with epilepsy has led to new animal models, more precise diagnoses and, in some cases, targeted therapies.

Abstract
The aim of this study was to describe sociodemographic, clinical, behavioral, nutritional, and health-related variables from people with epilepsy. A descriptive observational study was carried out in the city of Pelotas, southern Brazil. Sociodemographic, clinical, behavioral, nutritional, and health-related variables were collected. A univariate analysis was performed, calculating the measures of central tendency for continuous variables and proportions for categorical ones. The sample consisted of 101 people, age ranging from 12 to 75years, mostly male (50.5%) and white (59.4%). Only 37.2% from the sample was employed, and the average income was R$ 788.00 Brazilian Reais (US$ 245.90 at the moment of the interview). From all the subjects, 65.6% was in treatment with monotherapy, 62.9% presented more than 15 seizures during the life, 67.3% showed active epilepsy, 64.6% were physically inactive, 52.5% presented normal body mass index, and 50% showed generalized seizures. The most used antiepileptic drug was the carbamazepine. The average score of depression was 12.6±4.1 points and 34.6% showed severe depressive symptoms (equal or higher than 15 points). The mean score of trait and state anxiety was 12.2±3.6 and 15.1±3.4 points, respectively (ranging from 6 to 24 points). The mean score of quality of life and stress was 63.2±18.2 (ranging from 0 to 100 points) and 21.2±7.1 points (ranging from 0 to 40 points), respectively. Considering the medication side effects, the mean score was 42.4±8.9 points, 38.5% showing high rates (higher than 45 points), and only 16% showing good sleep quality. In conclusion, these results are important to improve understanding of these individuals' disease and to subsidize the specific public policies in countries of low and middle income.

Abstract
Epilepsy is a neurologic condition which often occurs with other neurologic and psychiatric disorders. The relation between epilepsy and these conditions is complex. Some population-based studies have identified a bidirectional relation, whereby not only patients with epilepsy are at increased risk of suffering from some of these neurologic and psychiatric disorders (migraine, stroke, dementia, autism, depression, anxiety disorders, Attention deficit hyperactivity disorder (ADHD), and psychosis), but also patients with these conditions are at increased risk of suffering from epilepsy. The existence of common pathogenic mechanisms has been postulated as a potential explanation of this phenomenon. To reassess the relationships between neurological and psychiatric conditions in general, and specifically autism, depression, Alzheimer's disease, schizophrenia, and epilepsy, a recent meeting brought together basic researchers and clinician scientists entitled "Epilepsy as a Network Disorder." This was the fourth in a series of conferences, the "Fourth International Halifax Conference and Retreat". This manuscript summarizes the proceedings on potential relations between Epilepsy on the one hand and autism and depression on the other. A companion manuscript provides a summary of the proceedings about the relation between epilepsy and Alzheimer's disease and schizophrenia, closed by the role of translational research in clarifying these relationships. The review of the topics in these two manuscripts will provide a better understanding of the mechanisms operant in some of the common neurologic and psychiatric comorbidities of epilepsy.

Abstract
The new definition of epilepsy establishes that epilepsy is not only a disorder presenting with epileptic seizures but it can be often associated with cognitive and psychiatric comorbidities. In fact, the prevalence of psychiatric comorbidities is relatively high in patients with epilepsy (PWE), as one in three patients will have experienced a psychiatric disorder in the course of their life, with mood and anxiety disorders being the most frequent. Psychiatric comorbidities often precede the onset of the seizure disorder, and affect the life of these patients and the course of the seizure disorder at several levels, including a worse tolerance of pharmacotherapy with antiepileptic drugs (AEDs), in particular the development of iatrogenic psychiatric symptoms from pharmacologic and surgical treatments, an increased mortality risk, a worse quality of life and higher economic burdens of the patient, family and society as a hole. Accordingly, psychiatric comorbidities should be recognized at the time of the initial evaluation of every PWE and their treatment needs to be incorporated within the overall therapeutic plan. This question is addressed in this article.

Epilepsy Behav 2017; 69:133-138. [PMID: 28259063 DOI: 10.1016/j.yebeh.2017.01.007] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2016] [Revised: 12/22/2016] [Accepted: 01/07/2017] [Indexed: 11/16/2022]
Abstract
INTRODUCTION Depression is the most frequent psychiatric co-morbidity in patients with epilepsy. Lifetime prevalence of depression is reported more frequently in temporal lobe epilepsy and is estimated at 35%. This co-morbidity appears to be related with various mechanisms. The aim of this study was to determine the quality of life (QoL) of patients with pharmacoresistant epilepsy with and without co-morbid depression in an Argentinean population. METHODS Patients admitted to the video-EEG monitoring unit during the period 2010-2013 went through a standardized psychiatric assessment using SCID-I (Structured Clinical Interview for Axis I diagnoses of DSM-IV), BDI II (Beck Depression Inventory) GAF (Global assessment of functioning), and Q LES Q-SF (for quality of life). Patients were divided in two groups: with and without depression (according to DSM-IV). Sociodemographic data, BDI II scores, GAF, and quality of life (QoL) were compared between the two groups. Comparisons were made using Student's t-test and Mann-Whitney U test. Frequency distributions were compared by Chi-square test. Spearman correlation coefficients were determined. RESULTS Seventy-seven patients with pharmacoresistant epilepsy were eligible for this study, 41 patients were included in the group with depression (mean BDI II 15.93), and 36 in the group without depression (mean BDI II 3.36) (p=0.001). The overall QoL was significantly lower in the group with depression compared to the group without depression (p<0.01). The most affected areas were: physical health (p=0.013), mood (p=0.006), course activities (referring to school as well as to hobbies or classes outside of school) (p=0.003), leisure time activities (p=0.011), social activities (p=0.047), general activities (p=0.042), and medication (p=0.022). Severity of depression according to BDI II had a negative correlation with overall QoL (r - 0.339, p<0.01). No correlations were found between seizure frequency, QoL and BDI II. CONCLUSION Patients with pharmacoresistant epilepsy and co-morbid depression reported worst QoL. Depression disrupts daily functioning (leisure, social functioning) and is a negative influence for subjective perception of health and medication. Interdisciplinary treatment should be considered (neurology-psychiatry-psychotherapy).

Abstract
Aim: Antiepileptic drugs do cause adverse effects, affecting patients’ quality of life, adherence and seizures. Consequently, there is a need to study this among Nigerian patients. Methods: Descriptive cross-sectional study assessing the extent of adverse effects with carbamazepine monotherapy and potential factors. Results: 54 patients (64.3%) reported no adverse effects, while 30 did. The most common adverse effects were memory problems followed by headaches, restlessness, tiredness and depression. Adverse effects were significantly higher in females, with females with low educational levels having significantly higher rates. Dose, co-medications, seizure control and comorbid conditions did not significantly affect adverse effects. Conclusion: Perception of adverse effects was common in patients on carbamazepine monotherapy, more common in women than men. Educational status was important in women.

Abstract
The prevalence of psychiatric comorbidities is relatively high in people with epilepsy (PWE), as one in three patients will have experienced a psychiatric disorder in the course of their life. The new definition of epilepsy recognizes these comorbidities as part of the seizure disorder, which need to be recognized and treated together with the actual epileptic seizures. Psychiatric comorbidities have a complex relation with epilepsy, being associated with a negative course of the seizure disorder, worse tolerance of pharmacotherapy with AEDs, development of iatrogenic psychiatric complications from pharmacologic and surgical treatments, and increased mortality risks. Given their negative impact at several levels of the lives of PWE, should psychiatric comorbidities be included in a classification of the epilepsies? This question is addressed in this article. This article is part of a Special Issue entitled "The new approach to classification: Rethinking cognition and behavior in epilepsy".

Abstract
BACKGROUND In patients taking antiepileptic drugs (AEDs) for epilepsy, adverse effects (AEs) often lead to unfavorable quality of life, impaired adherence, and, eventually, discontinuation of pharmacological treatment. In a true-to-life sample of subjects from our academic epilepsy outpatient clinic, we aimed to identify predictors for overall high AE burden and for specific AEs focusing on patients on monotherapy. METHODS All patients ≥16years of age with epilepsy for ≥12months were routinely asked to complete the Liverpool Adverse Event Profile (LAEP) just before their appointment. Demographic, epilepsy, and treatment variables were derived from our comprehensive outpatient database. RESULTS Out of 841 patients, 438 (61% female, mean age: 44.7±17.1years) on monotherapy were included in this study. Levetiracetam (n=151), lamotrigine (n=167), valproic acid (n=73), or controlled-release carbamazepine (n=47) were the most commonly used antiepileptic drugs (AEDs). Independent predictors for general high AE burden (LAEP score≥45) were duration of epilepsy, lack of 12-month seizure freedom, and partial epilepsy, but none of the four individual AEDs. The most frequent LAEP-defined specific AEs were sleepiness, difficulty concentrating, tiredness, and memory problems. The three most frequent independent predictors for each of the 19 AEs were lack of 12-month seizure freedom (13/19 AEs), individual AED (7/19 AEs), and partial epilepsy (6/19 AEs). Levetiracetam was independently associated with anger/aggression, nervousness/agitation, upset stomach, depression, and sleep disturbance; lamotrigine with nervousness/agitation, upset stomach, and difficulty concentrating; and valproic acid with upset stomach and shaky hands. CONCLUSION Individual AEDs independently predicted some specific AEs, but not overall high AE burden. Our findings may help to characterize patients with epilepsy who are at high risk for specific AEs. Dose reduction or change to another AED may reduce LAEP score and potential nonadherence.

Gender differences in depression, but not in anxiety in people with epilepsy. Seizure 2015; 32:37-42.

Abstract
PURPOSE Anxiety and depression are frequent comorbidities in people with epilepsy (PWE), but possible gender differences are often neglected. The aim of the present study was to analyze if men and women with epilepsy differ with regard to anxiety and depressive symptoms and to identify possible predictors. METHODS Adult consecutive PWE (N=302; 53% women) completed self-report questionnaires, including the depression module of the Patient Health Questionnaire (PHQ-9), the anxiety module of the Hospital Anxiety and Depression Scale (HADS-A) and the subscales "medication effects" and "seizure worry" of the Patient-weighted Quality of Life in Epilepsy Inventory-31-P (QOLIE-31-P). RESULTS There was no gender difference in extent of anxiety (p=.532), which was mainly due to higher anxiety levels in men compared to the general population. The gender difference in depressive symptoms was significant (p=.009), with female patients being more affected. The most important predictors for anxiety and depressive symptoms were detrimental effects of medication (QOL medication effects) and of seizure worry (QOL seizure worry). Moreover, these predictors were more closely associated with anxiety and depressive symptoms in men. CONCLUSION Future intervention studies could show whether providing more information about the illness and medication effects may improve anxiety and depression. Our results suggest that such interventions should be tailored to the different needs of men and women.

Abstract
OBJECTIVE To provide evidence-based recommendations for treatment of adults with an unprovoked first seizure. METHODS We defined relevant questions and systematically reviewed published studies according to the American Academy of Neurology's classification of evidence criteria; we based recommendations on evidence level. RESULTS AND RECOMMENDATIONS Adults with an unprovoked first seizure should be informed that their seizure recurrence risk is greatest early within the first 2 years (21%-45%) (Level A), and clinical variables associated with increased risk may include a prior brain insult (Level A), an EEG with epileptiform abnormalities (Level A), a significant brain-imaging abnormality (Level B), and a nocturnal seizure (Level B). Immediate antiepileptic drug (AED) therapy, as compared with delay of treatment pending a second seizure, is likely to reduce recurrence risk within the first 2 years (Level B) but may not improve quality of life (Level C). Over a longer term (>3 years), immediate AED treatment is unlikely to improve prognosis as measured by sustained seizure remission (Level B). Patients should be advised that risk of AED adverse events (AEs) may range from 7% to 31% (Level B) and that these AEs are likely predominantly mild and reversible. Clinicians' recommendations whether to initiate immediate AED treatment after a first seizure should be based on individualized assessments that weigh the risk of recurrence against the AEs of AED therapy, consider educated patient preferences, and advise that immediate treatment will not improve the long-term prognosis for seizure remission but will reduce seizure risk over the subsequent 2 years.

Kim SK, Park SP, Kwon OY. Impact of depression and anxiety on adverse event profiles in Korean people with epilepsy. Epilepsy Behav 2015; 46:185-91. [PMID: 25869903 DOI: 10.1016/j.yebeh.2015.03.005] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2014] [Revised: 03/04/2015] [Accepted: 03/07/2015] [Indexed: 11/19/2022]
Abstract
Previous studies have shown that depression and anxiety worsen the adverse events associated with antiepileptic drugs (AEDs) in people with epilepsy. These studies used the Liverpool Adverse Events Profile (LAEP) to screen adverse events. The LAEP incorporates items associated with emotion, which may themselves influence the reporting of adverse events. We investigated whether depression and anxiety still displayed an effect on adverse events when items related to emotion were excluded from the analysis. A total of 453 consecutive patients with epilepsy who took AEDs for at least 1year completed self-report questionnaires, including the Korean versions of the LAEP (K-LAEP), the Beck Depression Inventory (K-BDI), and the Beck Anxiety Inventory (K-BAI). Firstly, we performed a discrimination analysis to identify the items affected by depression and/or anxiety among the 19 items included in the K-LAEP. Among these items, dizziness, nervousness and/or agitation, restlessness, and upset stomach had relatively higher levels of significance. Secondly, we performed a factor analysis to determine the subclass taxonomy of all items in the K-LAEP. The analysis segregated the items into three subclasses: cephalgia/coordination/sleep, emotion/cognition, and tegument/mucosa/weight. Lastly, we performed stepwise multiple regressions to demonstrate the predictors determining the K-LAEP and subclass scores. According to the regressions, the K-BAI and K-BDI scores and the duration of treatment of the antiepileptic medication were significant predictors. Specifically, the K-BAI score was a predictor of the scores of all three subclasses as well as the total K-LAEP score; the K-BDI score was a predictor of the total K-LAEP score and the emotion/cognition score; and the duration of treatment of the antiepileptic medication was a predictor of the tegument/mucosa/weight score. The K-BAI score was the strongest predictor of all the scores. Although this study showed a similar impact of depression and anxiety on the adverse event profiles as previous reports, it provided further insight into the contribution of the LAEP items associated with emotion. Other than the psychosocial predictors, the treatment duration of the antiepileptic medication was also found to be an important predictor in this study.

Abstract
Psychiatric comorbidities are relatively frequent in people with epilepsy, occurring in one of every three patients, with mood and anxiety disorders predominating. They are the expression of a complex interaction between a previous psychiatric history (and/or genetic predisposition for psychiatric disorder), neurobiologic changes associated with the underlying epilepsy, peri-ictal phenomena, iatrogenic and reactive processes. Furthermore, a bidirectional relation between psychiatric disorders and epilepsy has added another level of complexity, while at the same time opening an opportunity of the recognition of potential pathogenic mechanisms that are responsible for the high comorbid occurrence of these disorders. This article highlights the clinical implications of understanding the course of psychiatric comorbidities relative to the onset of the seizure disorder to minimize their risk of recurrence and their interference in the management of the seizure disorder.

Abstract
Persons with epilepsy (PWE) have a higher risk of developing depressive disorders (DDs), and people with primary DD have an increased risk of developing epilepsy. Furthermore, a lifetime history of DD has been associated with a worse response of the seizure disorder to pharmacotherapy and epilepsy surgery. The first part of this article reviews the literature of this problem with the intention of highlighting the neurobiologic pathogenic mechanisms operant in DD with a potential to facilitate the epileptogenic process and/or cortical hyperexcitability in humans and experimental animal studies of depression. They include the following: (i) a hyperactive hypothalamic-pituitary-adrenal axis and the associated structural and functional abnormalities of limbic structures, (ii) increased glutamatergic activity and decreased GABAergic and serotonergic activity, and (iii) immunologic disturbances. In the second part of this article, we suggest research strategies to test the hypothesis of whether depression worsens the course of epilepsy and identify the pathogenic mechanisms operant in this process.

Abstract
Phenobarbital remains one of the most widely used antiepileptic drugs worldwide, yet there are limited data regarding side effects associated with its use in routine clinical care settings in low-income countries. Available data suggests that phenobarbital is as effective as other first-line drugs for treating tonic-clonic seizures, but side effect reports differ widely between high and low-income settings. A better understanding of phenobarbital side effect profile and severity in low-income settings is warranted given its role in efforts to decrease the epilepsy treatment gap. We used the Liverpool adverse events profile (LEAP) to assess side effects in consecutive patients with epilepsy on phenobarbital seeking care in rural Zambia. Data regarding age, gender, medication dose, and medication adherence were also collected. T-tests and Spearman's correlation coefficient were used to assess predictors of LEAP score and medication adherence. Thirty-five patients receiving a mean dose of 2.1mg/kg/day (SD: 2.78 mg/kg/day) of phenobarbital were assessed. All participants reported at least one side effect in the previous four weeks with a median of 6 symptoms (IQR: 4-8) and a mean side effects score of 28/76 (SD: 5.38). Over half reported sleepiness and dizziness. Memory problems and depression were also common (both 46%). Total LAEP score was not associated with age (p=0.88), gender (p=0.17), or phenobarbital dose (p=0.13). Medication adherence was not associated with side effects total score (p=0.56). Rural Zambian adults taking phenobarbital at doses recommended by the World Health Organization report a significant number of side effects. The most common side effects reported were similar to those reported in high-income countries. The significant burden of phenobarbital-associated side effects in this African cohort is in contrast to data from non-randomized clinical trials in China that reported phenobarbital to be well-tolerated with few side effects. Additional investigations regarding phenobarbital side effects during routine care in low income settings is warranted.

Abstract
OBJECTIVE To evaluate whether vagus nerve stimulation (VNS) as adjunct to best medical practice (VNS + BMP) is superior to BMP alone in improving long-term health-related quality of life (HRQoL). METHODS PuLsE (Open Prospective Randomized Long-term Effectiveness) was a prospective, randomized, parallel-group, open-label, and long-term effectiveness study (conducted at 28 sites in Europe and Canada). Adults with pharmacoresistant focal seizures (n = 112) received VNS + BMP or BMP (1:1 ratio). Medications and VNS parameters could be adjusted as clinically indicated for optimal seizure control while minimizing adverse effects. Primary endpoint was mean change from baseline HRQoL (using Quality of Life in Epilepsy Inventory-89 total score; QOLIE-89). Secondary endpoints included changes in seizure frequency, responder rate (≥50% decrease in seizure frequency), Centre for Epidemiologic Studies Depression scale (CES-D), Neurological Disorders Depression Inventory-Epilepsy scale (NDDI-E), Clinical Global Impression-Improvement scale (CGI-I), Adverse Event Profile (AEP), and antiepileptic drug (AED) load. The study was prematurely terminated due to recruitment difficulties prior to completing the planned enrollment of n = 362. Results for n = 96 who had baseline and at least one follow-up QOLIE-89 assessment (from months 3-12) were included in this analysis. Mixed model repeated measures (MMRM) analysis of variance was performed on change from baseline for the primary and secondary endpoints. RESULTS Significant between-group differences in favor of VNS + BMP were observed regarding improvement in HRQoL, seizure frequency, and CGI-I score (respective p-values < 0.05, 0.03, and 0.01). More patients in the VNS + BMP group (43%) reported adverse events (AEs) versus BMP group (21%) (p = 0.01), a difference reflecting primarily mostly transient AEs related to VNS implantation or stimulation. No significant difference between treatment groups was observed for changes in CES-D, NDDI-E, AEP, and AED load. SIGNIFICANCE VNS therapy as a treatment adjunct to BMP in patients with pharmacoresistant focal seizures was associated with a significant improvement in HRQoL compared with BMP alone.

Abstract
In this review, we attempt to bring the reader up to date with recent developments in the area of assessment of quality of life (QOL) of patients with epilepsy, in both the research and clinical contexts. We present evidence from recent publications on the major and most commonly used QOL instruments for both adults and children with epilepsy, including both strengths and limitations. We discuss both generic measures and ones that have been developed specifically for use in the epilepsy population. We draw attention to some of the broader issues that render the QOL assessment endeavor a somewhat complex one - in particular, that epilepsy is not a single condition, with a common clinical trajectory; and that QOL measures as currently configured almost universally focus on its negative impacts, largely neglecting the possibility of those affected being able to retain reasonable social adjustment and life satisfaction. Finally, we suggest that further work needs to focus on plugging the current evidence gaps in relation to psychometric and cross-cultural applicability issues; and on the value of QOL instruments in the clinical care setting. We conclude by highlighting a number of issues from the QOL literature that will, in our view, be the focus of increasing research interest in the next few years.
