Abstract
Binge eating disorder (BED) is the most common specific eating disorder (ED). It is frequently associated with attention deficit hyperactivity disorder (ADHD), depression, bipolar disorder (BD), anxiety disorders, alcohol and nicotine use disorder, and obesity. The aim of this narrative review was to summarize the evidence for the pharmacological treatment of BED and its comorbid disorders. We recommend the ADHD medication lisdexamfetamine (LDX) and the antiepileptic and antimigraine drug topiramate for the pharmacological treatment of BED. However, only LDX is approved for the treatment of BED in some countries. Medications to treat diseases frequently comorbid with BED include atomoxetine and LDX for ADHD; citalopram, fluoxetine, sertraline, duloxetine, and venlafaxine for anxiety disorders and depression; aripiprazole for manic episodes of BD; lamotrigine, lirasidone and lumateperone for depressive episodes of BD; naltrexone for alcohol use disorder; bupropion for nicotine use disorder; and liraglutide, semaglutide, and the combination of bupropion and naltrexone for obesity. As obesity is a frequent health consequence of BED, weight gain-inducing medications, such as the atypical antipsychotics olanzapine or clozapine, the novel antidepressant mirtazapine and tricyclic antidepressants, and the mood stabilizer valproate should be avoided where possible. It is currently unclear whether the novel and promising glucagon, glucose-dependent insulinotropic polypeptide (GIP), and glucagon-like peptide 1 (GLP-1) receptor agonists like tirzepatide and retatrutide help with BED and its comorbidities. However, these compounds have been reported to reduce binge eating in individuals with obesity or overweight.

[PMID: 38593493 DOI: 10.1016/j.yebeh.2024.109728] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 02/26/2024] [Accepted: 02/27/2024] [Indexed: 04/11/2024]
Abstract
OBJECTIVE Postictal psychiatric symptoms (PPS) are a relatively common but understudied phenomenon in epilepsy. The mechanisms by which seizures contribute to worsening in psychiatric symptoms are unclear. We aimed to identify PPS prospectively during and after admission to the epilepsy monitoring unit (EMU) in order to characterize the postictal physiologic changes leading to PPS. METHODS We prospectively enrolled patients admitted to the EMU and administered repeat psychometric questionnaires during and after their hospital stay in order to assess for postictal exacerbations in four symptom complexes: anger/hostility, anxiety, depression, and paranoia. Electroclinical and electrographic seizures were identified from the EEG recordings, and seizure durations were measured. The severity of postictal slowing was calculated as the proportion of postictal theta/delta activity in the postictal EEG relative to the preictal EEG using the Hilbert transform. RESULTS Among 33 participants, 8 demonstrated significant increases in at least one of the four symptoms (the PPS+ group) within three days following the first seizure. The most common PPS was anger/hostility, experienced by 7/8 participants with PPS. Among the 8 PPS+ participants, four experienced more than one PPS. As compared to those without PPS (the PPS- group), the PPS+ group demonstrated a greater degree of postictal EEG slowing at 10 min (p = 0.022) and 20 min (p = 0.05) following seizure termination. They also experienced significantly more seizures during the study period (p = 0.005). There was no difference in seizure duration between groups. SIGNIFICANCE Postictal psychiatric symptoms including anger/hostility, anxiety, depression, and paranoia may be more common than recognized. In particular, postictal increases in anger and irritability may be particularly common. We provide physiological evidence of a biological mechanism as well as a demonstration of the use of quantitative electroencephalography toward a better understanding of postictal neurophysiology.

Abstract
OBJECTIVE This study was undertaken to ascertain the natural history and patterns of antiseizure medication (ASM) use in newly diagnosed focal epilepsy patients who were initially started on monotherapy. METHODS The data were derived from the Human Epilepsy Project. Differences between the durations of the most commonly first prescribed ASM monotherapies were assessed using a Cox proportional hazards model. Subjects were classified into three groups: monotherapy, sequential monotherapy, and polytherapy. RESULTS A total of 443 patients were included in the analysis, with a median age of 32 years (interquartile range [IQR] = 20-44) and median follow-up time of 3.2 years (IQR = 2.4-4.2); 161 (36.3%) patients remained on monotherapy with their initially prescribed ASM at the time of their last follow-up. The mean (SEM) and median (IQR) duration that patients stayed on monotherapy with their initial ASM was 2.1 (2.0-2.2) and 1.9 (.3-3.5) years, respectively. The most commonly prescribed initial ASM was levetiracetam (254, 57.3%), followed by lamotrigine (77, 17.4%), oxcarbazepine (38, 8.6%), and carbamazepine (24, 5.4%). Among those who did not remain on the initial monotherapy, 167 (59.2%) transitioned to another ASM as monotherapy (sequential monotherapy) and 115 (40.8%) ended up on polytherapy. Patients remained significantly longer on lamotrigine (mean = 2.8 years, median = 3.1 years) compared to levetiracetam (mean = 2.0 years, median = 1.5 years) as a first prescribed medication (hazard ratio = 1.5, 95% confidence interval = 1.0-2.2). As the study progressed, the proportion of patients on lamotrigine, carbamazepine, and oxcarbazepine as well as other sodium channel agents increased from a little more than one third (154, 34.8%) of patients to more than two thirds (303, 68.4%) of patients. SIGNIFICANCE Slightly more than one third of focal epilepsy patients remain on monotherapy with their first prescribed ASM. Approximately three in five patients transition to monotherapy with another ASM, whereas approximately two in five end up on polytherapy. Patients remain on lamotrigine for a longer duration compared to levetiracetam when it is prescribed as the initial monotherapy.

Abstract
INTRODUCTION In past years, a possible bidirectional link between epilepsy and Alzheimer's disease (AD) has been proposed: if AD patients are more likely to develop epilepsy, people with late-onset epilepsy evidence an increased risk of dementia. Furthermore, current research suggested that subclinical epileptiform discharges may be more frequent in patients with AD and network hyperexcitability may hasten cognitive impairment. AREAS COVERED In this narrative review, the authors discuss the recent evidence linking AD and epilepsy as well as seizures semeiology and epileptiform activity observed in patients with AD. Finally, anti-seizure medications (ASMs) and therapeutic trials to tackle seizures and network hyperexcitability in this clinical scenario have been summarized. EXPERT OPINION There is growing experimental evidence demonstrating a strong connection between seizures, neuronal hyperexcitability, and AD. Epilepsy in AD has shown a good response to ASMs both at the late and prodromal stages. The new generation ASMs with fewer cognitive adverse effects seem to be a preferable option. Data on the possible effects of network hyperexcitability and ASMs on AD progression are still inconclusive. Further clinical trials are mandatory to identify clear guidelines about treatment of subclinical epileptiform discharges in patients with AD without seizures.

Abstract
PURPOSE Depression and anxiety are psychiatric disorders related to chronic stress, commonly found in patients with drug-resistant epilepsy (DRE) and functional dissociative seizures (FDS). The present study compares the levels of perceived stress, resilience, and the styles of stress coping among patients with DRE (n=60), FDS (n=28), and controls (n=31). METHODS We performed a cross-sectional study. All patients underwent Video Electroencephalography to confirm the diagnosis and completed the psychiatric assessment (SCID I and II of DSM IV) supported by several instruments validated in Spanish. RESULTS FDS scored higher in perceived stress (p = 0.004) with lower levels of resilience compared to controls (p = 0.01). Stress coping subscales show higher scores in negative self-focus and hostility in patients with FDS compared to controls (p=0.003). Similarly, DRE patients scored higher in perceived stress (p = 0.001), and presented lower levels of resilience (p = 0.004) with higher levels of hostility compared to controls (p=0.02). However, no significant differences were found between FDS and DRE on stress coping variables. Anxiety scores and depression rates were higher in the FDS group compared to DRE (p=0.008) and higher in DRE compared to controls (p<0.05). A positive correlation between depression and perceived stress was found (r = 0.6, p=0.0001). CONCLUSIONS Our results delineate a more detailed picture of the psychological profile of this population, emphasizing the importance of stress factors in patients with FDS and DRE. Combined intervention strategies which enhance stress coping may be appropriate to direct treatment and psychotherapy.

Abstract
Primary impulsive aggression (PIA) can be implicated as a common factor that results in an arrest, disciplinary, and restraint measures during confinement, and criminal recidivism after release. Evidence suggests that anti-impulsive aggression agents (AIAAs) can diminish or prevent impulsive aggression even when occurring with personality pathology such as borderline or antisocial personality disorder (ASPD), common conditions in offender populations. A previous review identified agents that have been subjected to controlled drug trials of sufficient quality, and subsequently, a decisional algorithm was developed for selecting an AIAA for individuals with IA. This selection process began with the five agents that showed efficacy in two or more quality studies from the earlier review. Today, 8 years after the quality review study, the present authors undertook this follow-up literature review. The aims of the present review were to survey the literature to identify and assess: (1) drug trials of comparable quality published since the 2013 review, including trials of the previously identified AIAAs as well as trials of agents not included in the earlier review; (2) severity of aggressive outbursts; (3) the materiality of risks or side-effects that are associated with individual AIAAs as well as antipsychotic agents commonly used to control clinical aggression; (4) efficacy of these agents in special populations (e.g., females); and (5) cost and convenience of each agent. Improved pharmacotherapy of PIA by addressing risks, side effects and practicality as well as the efficacy of AIAAs, should promote the rehabilitation and reintegration of some pathologically aggressive offenders back into the community.

Kawai M, Goji H, Kanemoto K. Differences in aggression as psychiatric side effect of levetiracetam and perampanel in patients with epilepsy. Epilepsy Behav 2022; 126:108493. [PMID: 34933187 DOI: 10.1016/j.yebeh.2021.108493] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 12/02/2021] [Accepted: 12/02/2021] [Indexed: 01/08/2023]
Abstract
PURPOSE Aggression is the most commonly encountered antiepileptic-drug (AED)-induced psychiatric adverse effects. Levetiracetam (LEV) is well known to be associated with increased rates of aggression, while perampanel (PER) is also recognized as a potentially aggression-promoting agent, though opinions vary. However, few studies have addressed questions regarding whether the nature of irritability-aggression differs between those drugs. The present study used a standardized rating scale to examine aggression among patient with epilepsy who received LEV or PER using specific measures to confirm the effects of the drugs. METHODS We enrolled 144 consecutive outpatients receiving treatment for epilepsy with LEV (n = 103) or PER (n = 41), and determined their effects regarding aggression using the Buss-Perry Aggression Questionnaire (BAQ). For analysis, total BAQ scores for the LEV and PER subjects were compared to determine whether the aggression-promoting effects of the agents differed, and which BAQ subdomains (physical aggression, verbal aggression, anger, hostility) were related to production of aggression in patients taking either LEV or PER. As a subsidiary analysis, clinical variables inclusive of administered AED type that showed a significant impact on BAQ scores were determined. RESULTS The LEV group had a significantly higher hostility score (19.4 ± 5.8) as compared to the PER group (17.2 ± 6.3) in subscale analysis (p < 0.05). In multiple regression analysis, LEV had a significant association with higher hostility score (P = 0.006). CONCLUSION Our results indicate that while easily visible outward-directed aggression tends to be dominant in patients given PER, aggression provoked by LEV may be felt more subjectively or in an inward-directed manner, which can lead to more diverse expression and misrecognition.

Abstract
PURPOSE Aggression-irritability is the most commonly encountered antiepileptic-drug-induced psychiatric adverse effects. In this cross-sectional study, we tried to assess antiepileptic-drug-induced aggression in patients with epilepsy (PWE) with a standardized rating scale. METHODS Two hundred sixty-six consecutive outpatients receiving treatment for epilepsy with antiepileptic drugs (AEDs) were initially examined, and the effects of the investigated drugs in regard to aggression were investigated using the Buss-Perry Aggression Questionnaire (BAQ). We compared BAQ scores as a function of a specific class of AEDs, levetiracetam (LEV), lacosamaide (LCM), perampanel (PER), and carbamazepine (CBZ), and determined whether AED type had a relationship with aggression. Additionally, the association of BAQ score with other clinico-demographic variables was also assessed. RESULTS One-way ANOVA revealed that the LEV group had a significantly higher mean BAQ score as compared to the CBZ (P = 0.001) and LCM (P = 0.029) groups for total score. In subscale analysis, the LEV group had higher scores than the CBZ group for the physical aggression (p = 0.01), verbal aggression (p = 0.02) and hostility (p = 0.01) subscales, while the LEV group had a significantly higher mean score than the LCM group for hostility (p = 0.025). In multiple regression analysis, LEV had a statistically significant impact on increased total BAQ score (B = 0.119, p = 0.049). In contrast, CBZ (B = -0.191, p = 0.002), older age at epilepsy onset (B = -0.269, p = 0.000) and female gender (B = -0.210, p = 0.000) had a significant association with lower total BAQ score. CONCLUSIONS Our results indicate that LEV is associated with increased aggression, while CBZ and LCM showed effects to reduce aggression.

Integration of postmortem amygdala expression profiling, GWAS, and functional cell culture assays: neuroticism-associated synaptic vesicle glycoprotein 2A (SV2A) gene is regulated by miR-133a and miR-218. Transl Psychiatry 2020; 10:297. [PMID: 32839459 PMCID: PMC7445165 DOI: 10.1038/s41398-020-00966-4] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 07/15/2020] [Accepted: 07/28/2020] [Indexed: 12/27/2022] Open
Abstract
Recent genome-wide studies have begun to identify gene variants, expression profiles, and regulators associated with neuroticism, anxiety disorders, and depression. We conducted a set of experimental cell culture studies of gene regulation by micro RNAs (miRNAs), based on genome-wide transcriptome, proteome, and miRNA expression data from twenty postmortem samples of lateral amygdala from donors with known neuroticism scores. Using Ingenuity Pathway Analysis and TargetScan, we identified a list of mRNA-protein-miRNA sets whose expression patterns were consistent with miRNA-based translational repression, as a function of trait anxiety. Here, we focused on one gene from that list, which is of particular translational significance in Psychiatry: synaptic vesicle glycoprotein 2A (SV2A) is the binding site of the anticonvulsant drug levetiracetam ((S)-α-Ethyl-2-oxo-1-pyrrolidineacetamide), which has shown promise in anxiety disorder treatments. We confirmed that SV2A is associated with neuroticism or anxiety using an original GWAS of a community cohort (N = 1,706), and cross-referencing a published GWAS of multiple cohorts (Ns ranging from 340,569 to 390,278). Postmortem amygdala expression profiling implicated three putative regulatory miRNAs to target SV2A: miR-133a, miR-138, and miR-218. Moving from association to experimental causal testing in cell culture, we used a luciferase assay to demonstrate that miR-133a and miR-218, but not miR-138, significantly decreased relative luciferase activity from the SV2A dual-luciferase construct. In human neuroblastoma cells, transfection with miR-133a and miR-218 reduced both endogenous SV2A mRNA and protein levels, confirming miRNA targeting of the SV2A gene. This study illustrates the utility of combining postmortem gene expression data with GWAS to guide experimental cell culture assays examining gene regulatory mechanisms that may contribute to complex human traits. Identifying specific molecular mechanisms of gene regulation may be useful for future clinical applications in anxiety disorders or other forms of psychopathology.

Abstract
INTRODUCTION Depression is the most common psychiatric comorbidity in people with epilepsy. It worsens the prognosis and quality of life of these patients. Despite this, depression is poorly diagnosed and when the treatment is given, it is frequently suboptimal. OBJECTIVE To perform a narrative review of the medical literature, seeking to collect useful information regarding the relationship between epilepsy and depression. RESULTS Narrative reviews, systematic reviews, meta-analyses, clinical trials, and follow-up studies were identified in English and Spanish with no time limit, including epidemiological, clinical, associated factors, etiological explanations, diagnostic and therapeutic approaches to comorbid depression in epilepsy. CONCLUSION The relationship between epilepsy and depression is complex. The available scientific evidence suggests the possibility of a bidirectional relationship that could be explained from common aetiopathogenic mechanisms. Despite the high prevalence of depression in epileptic patients, this mental disorder continues to be poorly identified by clinicians. To improve this, we have easy-to-apply instruments that routinely screen this patient population and contribute substantially to making the problem more visible and seek to improve the quality of life for this population.

Abstract
OBJECTIVE This study compared the effect of levetiracetam (LEV) as monotherapy to sodium valproate (VPA) as monotherapy on cognitive functions in patients with epilepsy. METHODS This was a comparative prospective study on 50 patients with newly diagnosed epilepsy started on antiseizure medications. Patients were selected from the neurology-outpatient clinics at Minia University Hospital, Minia, Egypt. They were divided into two groups: group treated with LEV and group treated with VPA. All patients were subjected to cognitive function assessment using reaction-time tests, trail-making tests, and Wisconsin card-sorting test before treatment and 3 months after treatment. RESULTS Both groups of patients showed reduction in seizure frequency. However, patients on LEV showed significant improvement in measured cognitive functions 3 months after starting treatment, while patients in the VPA group showed significant impairment in measured cognitive functions 3 months after starting treatment. CONCLUSION Both groups of patients showed reduction in seizure frequency. However, patients on LEV showed significant improvement in measured cognitive functions 3 months after starting treatment, while patients in the VPA group showed significant impairment in measured cognitive functions 3 months after starting treatment.

Abstract
Until the early 1990s, a limited number of antiepileptic drugs (AEDs) were available. Since then, a large variety of new AEDs have been developed and introduced, several of them offering new modes of action. One of these new AED families is described and reviewed in this article. Levetiracetam (LEV) and brivaracetam (BRV) are pyrrolidone derivate compounds binding at the presynaptic SV2A receptor site and are thus representative of AEDs with a unique mode of action. LEV was extensively investigated in randomized controlled trials and has a very promising efficacy both in focal and generalized epilepsies. Its pharmacokinetic profile is favorable and LEV does not undergo clinically relevant interactions. Adverse reactions comprise mainly asthenia, somnolence, and behavioral symptoms. It has now been established as a first-line antiepileptic drug. BRV has been recently introduced as an adjunct antiepileptic drug in focal epilepsy with a similarly promising pharmacokinetic profile and possibly increased tolerability concerning psychiatric adverse events. This review summarizes the essential preclinical and clinical data of LEV and BRV that is currently available and includes the experiences at a large tertiary referral epilepsy center.

Cognitive, behavioural and sleep-related adverse effects on introduction of levetiracetam versus oxcarbazepine for epilepsy. Epilepsy Res 2019; 150:58-65. [PMID: 30641352 DOI: 10.1016/j.eplepsyres.2019.01.004] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2018] [Revised: 12/16/2018] [Accepted: 01/07/2019] [Indexed: 11/29/2022]
Abstract
OBJECTIVE There is limited literature on cognitive, behaviour and sleep-related adverse effects of levetiracetam and oxcarbazepine among adult epilepsy patients, except for what is available from the initial efficacy trials. This study was initiated with the aim to evaluate the incidence and prevalence of various cognitive, behaviour and sleep-related adverse effects of levetiracetam versus oxcarbazepine among people with epilepsy. METHODS The study was conducted in two parts: part A was a cross-sectional study, and part B was a longitudinal study. Trail making test A & B, digit symbol substitution test, Stroop colour and word test, controlled oral word association test and PGI memory scale, Neuropsychiatric Inventory, sleep log and ESS-I were used for assessment of cognitive, behaviour and sleep-related adverse effects. RESULTS In the cross-sectional as well as prospective study, no significant difference was observed in the cognitive performance of patients in levetiracetam and oxcarbazepine group in any of the cognitive assessment. Among 120 patients enrolled in the cross-sectional study, significantly higher number of patients in the levetiracetam group compared to the oxcarbazepine group,had agitation/aggression (20% vs10%, p = 0.047) and irritability (26.7% vs 3.3%, p = 0.007).Among 132 patients enrolled in the prospective study, significantly higher increase in the domain score of agitation/aggression (14.5% vs 1.6%, p = 0.028) and irritability (17.7% vs 1.6%, p = 0.018) was observed in the levetiracetam group compared to oxcarbazepine group. A significantly higher proportion of patients in the oxcarbazepine group had hypersomnolence (11.3% vs 1.6%, p = 0.026), as compared to the levetiracetam group. SIGNIFICANCE On cross-sectional as well as on longitudinal assessment, nearly one-fifth of patients on levetiracetam have behaviour related adverse effects, with dose modification required for half among these. Nearly 11% of patients on oxcarbazepine reported sleep-related adverse effects (higher total sleep duration per 24 h).

Abstract
OBJECTIVE To evaluate the efficacy, safety and economics of levetiracetam (LEV) for epilepsy. MATERIALS AND METHODS PubMed, Scopus, the Cochrane Library, OpenGrey.eu and ClinicalTrials.gov were searched for systematic reviews (SRs), meta-analyses, randomized controlled trials (RCTs), observational studies, case reports and economic studies published from January 2007 to April 2018. We used a bubble plot to graphically display information of included studies and conducted meta-analyses to quantitatively synthesize the evidence. RESULTS A total of 14,803 records were obtained. We included 30 SRs/meta-analyses, 34 RCTs, 18 observational studies, 58 case reports and 2 economic studies after the screening process. The included SRs enrolled patients with pediatric epilepsy, epilepsy in pregnancy, focal epilepsy, generalized epilepsy and refractory focal epilepsy. Meta-analysis of the included RCTs indicated that LEV was as effective as carbamazepine (CBZ; treatment for 6 months: 58.9% vs 64.8%, OR=0.76, 95% CI: 0.50-1.16; 12 months: 54.9% vs 55.5%, OR=1.24, 95% CI: 0.79-1.93), oxcarbazepine (57.7% vs 59.8%, OR=1.34, 95% CI: 0.34-5.23), phenobarbital (50.0% vs 50.9%, OR=1.20, 95% CI: 0.51-2.82) and lamotrigine (LTG; 61.5% vs 57.7%, OR=1.22, 95% CI: 0.90-1.66). SRs and observational studies indicated a low malformation rate and intrauterine death rate for pregnant women, as well as low risk of cognitive side effects. But psychiatric and behavioral side effects could not be ruled out. LEV decreased discontinuation due to adverse events compared with CBZ (OR=0.52, 95% CI: 0.41-0.65), while no difference was found when LEV was compared with placebo and LTG. Two cost-effectiveness evaluations for refractory epilepsy with decision-tree model showed US$ 76.18 per seizure-free day gained in Canada and US$ 44 per seizure-free day gained in Korea. CONCLUSION LEV is as effective as CBZ, oxcarbazepine, phenobarbital and LTG and has an advantage for pregnant women and in cognitive functions. Limited evidence supports its cost-effectiveness.

Mechanisms Underlying Aggressive Behavior Induced by Antiepileptic Drugs: Focus on Topiramate, Levetiracetam, and Perampanel. Behav Neurol 2018; 2018:2064027.

Abstract
Antiepileptic drugs (AEDs) are effective against seizures, but their use is often limited by adverse effects, among them psychiatric and behavioral ones including aggressive behavior (AB). Knowledge of the incidence, risk factors, and the underlying mechanisms of AB induced by AEDs may help to facilitate management and reduce the risk of such side effects. The exact incidence of AB as an adverse effect of AEDs is difficult to estimate, but frequencies up to 16% have been reported. Primarily, levetiracetam (LEV), perampanel (PER), and topiramate (TPM), which have diverse mechanisms of action, have been associated with AB. Currently, there is no evidence for a specific pharmacological mechanism solely explaining the increased incidence of AB with LEV, PER, and TPM. Serotonin (5-HT) and GABA, and particularly glutamate (via the AMPA receptor), seem to play key roles. Other mechanisms involve hormones, epigenetics, and “alternative psychosis” and related phenomena. Increased individual susceptibility due to an underlying neurological and/or a mental health disorder may further explain why people with epilepsy are at an increased risk of AB when using AEDs. Remarkably, AB may occur with a delay of weeks or months after start of treatment. Information to patients, relatives, and caregivers, as well as sufficient clinical follow-up, is crucial, and there is a need for further research to understand the complex relationship between AED mechanisms of action and the induction/worsening of AB.

Abstract
This study compared the frontal lobe functioning and anger rumination between patients with epilepsy and healthy individuals. The second objective was to examine the efficacy of levetiracetam therapy on frontal lobe dysfunctions and anger rumination in patients with epilepsy. Participants (50 patients with epilepsy and 50 healthy individuals) completed the Frontal Assessment Battery (FAB) and Anger Rumination Scale (ARS). The patients had two testing sessions: pre- and post-levetiracetam therapies. The results showed that patients with epilepsy had frontal lobe dysfunctions in contrast with healthy individuals. Patients with epilepsy had higher anger rumination than healthy individuals. Compared with baseline performance, frontal lobe dysfunctions and anger rumination were significantly reduced after three months of levetiracetam therapy in patients with epilepsy. It is concluded that levetiracetam therapy may be beneficial in improving frontal lobe functioning and anger rumination thought pattern in patients with epilepsy. However, further studies are required to confirm this evidence.

Abstract
People with epilepsy (PWE) often suffer psychiatric symptoms which can impact them more than seizures. Affective and psychotic disorders are well recognized as occurring more frequently in PWE than the general population. Less is known about obsessive-compulsive disorder (OCD) in PWE, despite it being as disabling and distressing. We sought to explore the association between epilepsy and OCD with casereports by identifying ten PWE and concomitant OCD. Demographics, seizure classification, neurological, surgical, psychiatric and psychological treatment as well as quality of life were examined. A detailed analysis was performed for three of them, to explore the lived-experience of patients with the two conditions. This is followed by a discussion of how treatment for co-morbid epilepsy and OCD can be appropriately tailored to be patient specific and provide the greatest potential for improvement.

Abstract
OBJECTIVE To ascertain efficacy and tolerability of carbamazepine (CBZ), sodium valproate (VPA), lamotrigine (LTG) and levetiracetam (LEV) using the UKAED register (www.ukaed.info). METHODS Patients on CBZ (n=91), VPA (n=61), LTG (n=105), LEV (n=72) and healthy control subjects (CTR) on no medication (n=51) were extracted. All patients had anonymously provided information on seizure type and frequency and completed the Liverpool Adverse Event Profile (LAEP). RESULTS The number of seizure-free patients in the last 4 weeks was overall CBZ/VPA/LTG/LEV=60%/79%/67%/67%, for generalized epilepsy was CBZ/VPA/LTG/LEV=67%/89%/65%/94%, and for localization-related epilepsy was CBZ/VPA/LTG/LEV=59%/71%/67%/57%. Mean LAEP scores were CBZ/VPA/LTG/LEV/CTR=42.21/39.66/39.86/43.01/29.69. The mean LAEP was significantly higher in patients reporting depression and in patients with active epilepsy than in patients without depression and remission. Central nervous system (CNS) adverse effects including memory problems, difficulty concentrating, depression, unsteadiness, restlessness, feelings of anger, shaky hands and dizziness were significantly more frequent in CBZ, VPA, LTG and LEV than in CTR. The feeling of anger was significantly more frequent in LEV, and depression was significantly more frequent in CBZ compared to the other drugs. CONCLUSION In this Internet-based register of self-reported efficacy and tolerability, CBZ, VPA, LTG and LEV were similar. Self-reported CNS adverse effects were significantly more frequent than in controls. In addition, anger was associated with LEV and depression with CBZ. Confounding factors were depression and uncontrolled epilepsy.

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.

Abstract
Epilepsy is both a disease of the brain and the mind. Here, we present the second of two papers with extended summaries of selected presentations of the Third International Congress on Epilepsy, Brain and Mind (April 3-5, 2014; Brno, Czech Republic). Humanistic, biologic, and therapeutic aspects of epilepsy, particularly those related to the mind, were discussed. The extended summaries provide current overviews of epilepsy, cognitive impairment, and treatment, including brain functional connectivity and functional organization; juvenile myoclonic epilepsy; cognitive problems in newly diagnosed epilepsy; SUDEP including studies on prevention and involvement of the serotoninergic system; aggression and antiepileptic drugs; body, mind, and brain, including pain, orientation, the "self-location", Gourmand syndrome, and obesity; euphoria, obsessions, and compulsions; and circumstantiality and psychiatric comorbidities.

Abstract
Background Malignant brain tumors are unpredictable and incurable, with 5-year survival rates less than 30%. The poor prognosis combined with intensive treatment necessitates the inclusion of complementary and supportive therapies that optimize quality of life and reduce treatment-related declines in health. Exercise therapy has been shown to be beneficial in other cancer populations, but no evidence is available for brain cancer survivors. Therefore, we report results from 2 preliminary cases. Methods Two female patients diagnosed with glioblastoma multiforme and oligodendroglioma participated in a structured and supervised 12-week exercise program. The program consisted of two 1-hour resistance and aerobic exercise sessions per week and additional self-managed aerobic sessions. Outcome measures of strength, cardiovascular fitness, and several psychological indicators (depression, anxiety, and quality of life) were recorded at baseline, after 6 weeks and at the conclusion of the intervention. Results Exercise was well tolerated; both participants completed all 24 sessions and the home-based component with no adverse effects. Objective outcome measures displayed positive responses relating to reduced morbidity. Similar positive responses were found for psychological outcomes. Scores on the Hospital Anxiety and Depression Scale showed clinically meaningful improvements in depression and total distress. Conclusion These findings provide initial evidence that, despite the difficulties associated with brain cancer treatment and survivorship, exercise may be safe and beneficial and should be considered in the overall management of patients with brain cancer.

Abstract
This article reviews the current status of surgical treatment of epilepsy and introduces the ongoing challenges. Seizure outcome of resective surgery for focal seizures associated with focal lesions is satisfactory. Particularly for mesial temporal lobe epilepsy, surgical treatment should be considered from the earlier stage of the disease. Meanwhile, surgical outcome in nonlesional extratemporal lobe epilepsy is still to be improved using various approaches. Disconnective surgeries reduce surgical complications of extensive resections while achieving equivalent or better seizure outcomes. Multiple subpial transection is still being modified expecting a better outcome by transection to the vertical cortices along the sulci- and multi-directional transection from a single entry point. Hippocampal transection is expected to preserve memory function while interrupting the abnormal epileptic synchronization. Proper selection or combination of subdural and depth electrodes and a wide-band analysis of electroencephalography may improve the accurate localization of epileptogenic region. Patients for whom curative resective surgery is not indicated because of generalized or bilateral multiple nature of their epilepsies, neuromodulation therapies are options of treatment which palliate their seizures.

Abstract
Autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) is a focal epilepsy with attacks typically arising in the frontal lobe during non-rapid eye movement (NREM) sleep. It is characterized by clusters of complex and stereotyped hypermotor seizures, frequently accompanied by sudden arousals. Cognitive and psychiatric symptoms may be also observed. Approximately 12% of the ADNFLE families carry mutations on genes coding for subunits of the heteromeric neuronal nicotinic receptors (nAChRs). This is consistent with the widespread expression of these receptors, particularly the α4β2* subtype, in the neocortex and thalamus. However, understanding how mutant nAChRs lead to partial frontal epilepsy is far from being straightforward because of the complexity of the cholinergic regulation in both developing and mature brains. The relation with the sleep-waking cycle must be also explained. We discuss some possible pathogenetic mechanisms in the light of recent advances about the nAChR role in prefrontal regions as well as the studies carried out in murine models of ADNFLE. Functional evidence points to alterations in prefrontal GABA release, and the synaptic unbalance probably arises during the cortical circuit maturation. Although most of the available functional evidence concerns mutations on nAChR subunit genes, other genes have been recently implicated in the disease, such as KCNT1 (coding for a Na+-dependent K+ channel), DEPD5 (Disheveled, Egl-10 and Pleckstrin Domain-containing protein 5), and CRH (Corticotropin-Releasing Hormone). Overall, the uncertainties about both the etiology and the pathogenesis of ADNFLE point to the current gaps in our knowledge the regulation of neuronal networks in the cerebral cortex.

Abstract
PURPOSE We systematically reviewed studies to provide current evidence on the incidence and risk of skin rash in patients with LTG therapy. METHODS PubMed and Scopus databases, up to 15 March 2014 were searched to identify relevant studies. Eligible studies included prospective studies, retrospective studies and postmarketing reports, which included data of skin rash in patients with LTG therapy. RESULTS Forty-one articles met the entry criteria. A total of 4447 patients with LTG therapy from 26 prospective studies, 2977 patients from 8 retrospective studies, and 26,126 patients from 5/7 postmarketing reports were included. The overall incidence of skin rash with LTG therapy was 9.98% (444/4447) from prospective studies, 7.19% (214/2977) from retrospective studies, and 2.09% (547/26,126) from postmarketing reports. A meta-analysis of the risk of skin rash in 21 prospective studies, did not show a significant difference between patients with LTG and other drugs, including placebo, other ADEs or lithium (OR 0.99-2.41). In 6 respective studies, there was a significantly higher OR in patients with LTG compared with those with non-aromatic AEDs. However, there was no significant difference in rash risk between patients with LTG and aromatic AEDs. CONCLUSIONS Our study showed that LTG significantly increased the risk of developing a skin rash compared to non-aromatic AEDs. Our results support the need for large prospective population-based studies and clinical trials to determine whether LTG increases the risk of developing a skin rash than compared to other drugs.

Abstract
This study examined the relationship between task-switching abilities and displaced aggression in people with temporal lobe epilepsy (PWE). Participants (35 PWE and 35 healthy controls) performed emotion and gender classification switching tasks. People with temporal lobe epilepsy showed larger switch costs than controls. This result reflected task-switching deficits in PWE. People with temporal lobe epilepsy reported higher anger rumination, revenge planning, and behavioral displaced aggression compared with controls. Displaced aggression was a significant predictor of the task switch costs. It is suggested that displaced aggression is a significant marker of task-switching deficits.

Abstract
OBJECTIVE To report two cases of major depressive disorder in which lamotrigine (LTG) induced anger with murderous impulse. PATIENTS Case 1 was a 22-year-old man with symptoms of obsessive-compulsive disorder who developed major depressive disorder with antidepressant-induced hypomanic episodes. Case 2 was a 23-year-old woman experiencing an antidepressant-refractory depressive episode for whom remission was achieved by switching to a mood stabilizer and antipsychotics. In both cases LTG was started to treat the depressive episode. RESULTS Case 1 manifested with anger and murderous impulse when taking 125 mg/day of LTG. A reduction to 75 mg/day calmed this anger. Case 2 manifested with the same symptom when taking 25 mg/day of LTG, and the symptom immediately disappeared upon stopping LTG. CONCLUSIONS Use of LTG for epilepsy in intellectually disabled patients was reported to be associated with onset or exacerbation of aggressive or violent behavior. The two cases would suggest that LTG may cause anger so severe as to be accompanied with murderous impulse when administered to patients with mood disorders. Physicians should be cognizant of this possible, albeit infrequent, adverse effect even in use of LTG for mood disorders.

Abstract
BACKGROUND Nonconvulsive status epilepticus (NCSE) is a severe medical condition and heterogeneous disorder defined by different seizure types and diverse etiologies. NCSE occurs commonly in the elderly and is potentially misdiagnosed as a psychiatric disorder. Current treatment options for NCSE are still unsatisfactory. CASE PRESENTATION We report a case of NCSE in a 55-year-old epileptic male patient with a history of infectious encephalitis, disinhibitory behavior, and a suspected diagnosis of frontotemporal dementia. Add-on levetiracetam (LEV) to carbamazepine treatment improved clinical manifestations and abnormal electroencephalographic discharge. CONCLUSION With disinhibitory behavior in the elderly, the possibility of NCSE should be considered. Moreover, LEV may be an effective and well-tolerated pharmacotherapy for elderly NCSE patients.

Abstract
OBJECTIVES To ascertain the frequency of self-reported anger and depression in levetiracetam (LEV). DESIGN We compared patients with epilepsy (PWE) taking LEV with PWE taking other antiepileptic drugs (AEDs). SETTING All PWE and controls submitted information to the UK AED register. PARTICIPANTS We analysed the data of 418 PWE and 41 control participants. 158 participants took LEV in monotherapy or as part of polypharmacotherapy, 260 PWE took other AED. PRIMARY AND SECONDARY OUTCOME MEASURES All PWE and controls completed the Liverpool Adverse Event Profile (LAEP) which includes items on anger and depression quantified on a four-point Likert scale, with 1 indicating that there was never a problem; 2, rarely a problem; 3, sometimes a problem and 4, always or often a problem. RESULTS 49% of PWE on LEV and 39% on AED other than LEV reported anger as sometimes or always being a problem (p=0.042). 48% of PWE on LEV and 45% on AED other than LEV reported depression as sometimes or always being a problem (p=0.584). 7% of control participants reported anger as sometimes being a problem and 93% reported anger as never or rarely being a problem. Depression was never a problem in 75% of controls and rarely a problem in 25%. CONCLUSIONS Anger and depression were more frequently reported as a problem by PWE than by control participants. Our observational register of self-reported symptoms suggested anger being more often a problem in patients taking LEV than in PWE taking other AED. PWE should be informed about this potential problem of LEV.

Abstract
To compare the cognitive and behavioral effects of lamotrigine (LTG) to carbamazepine (CBZ) as monotherapy for pediatric epilepsy. A multicenter, randomized, open-label, parallel-group clinical trial was conducted in children with partial-onset seizures. LTG or CBZ was prescribed as monotherapy for previously untreated children and titrated over 8 weeks, followed by maintenance for 24 weeks. Outcome measures were change in cognition and behavior in a combined analysis of standardized measures from screening to the end of the maintenance phase, as well as antiepileptic efficacy and tolerability. A total of 67 children completed the study, including 32 of 43 (74.4%) treated with LTG and 35 of 41 (85.4%) treated with CBZ. Seizure-free outcomes did not differ between the intent-to-treat populations (53.5% LTG, 56.1% CBZ; p=0.81). There were no statistically significant differences in the intelligence of the two groups after treatment. Externalizing behavior problems improved in the CBZ group (p<0.05). However, there were no significant differences between the two groups in terms of externalizing behavior. The parents' report on the Conner scale showed an improvement in the CBZ group compared to the LTG group (p<0.05). LTG and CBZ showed similar efficacy and cognitive effects in treating childhood partial epilepsy. However, CBZ showed more benefits in improving externalizing behaviors.

Abstract
The aims of this paper are to identify factors that influence the psychosocial difficulties (PSDs) that persons with epilepsy experience in their everyday life, to describe their onset and the way they evolve over time, and to analyze the determinants of changes over time and other related variables. Electronic databases were searched for studies published in English between January 2005 and May 2010, and information from thirteen studies was extracted. The most frequent PSDs found in people with epilepsy were depressive symptoms, memory functions, quality of life, anxiety, stigma, locus of control, cognitive functions in general, and emotional functions in general. It can be stated that patients' life areas are affected by cognitive, emotional, and psychological problems. However, the majority of studies focus on isolated PSDs or on the effects of a specific determinant in the course of epilepsy, leaving some gaps that could encourage further research.

Abstract
Antiepileptic drugs (AEDs) can have both beneficial and adverse psychotropic effects. They act on neurotransmitter systems, neuronal ion permeability and other targets, although the exact mechanisms are not generally fully elucidated. A systematic review of the literature reveals evidence for both positive and negative effects on depression, anxiety, aggression, psychosis and sleep in patients with epilepsy. Topiramate, vigabatrin, levetiracetam, tiagabine and zonisamide have been associated primarily with adverse psychotropic effects, whilst gabapentin, pregabalin, lacosamide and lamotrigine, in particular, have demonstrated a more beneficial psychotropic profile, especially with regard to affective symptoms. This review, however, identifies specific methodological issues with studies that have reported on the psychotropic effects of AEDs, suggesting that some of the findings might be inconclusive or unreliable because of confounding factors, particularly the presence of psychiatric history. More rigorous double-blind, randomized, placebo-controlled trials on larger numbers of patients with epilepsy, with clear inclusion/exclusion criteria, that are specifically designed to investigate psychotropic changes are more likely to produce results that inform clinical practice and direct future research.

Abstract
Patients experiencing mental disorders are at an elevated risk for developing aggressive behavior. In the past 10 years, the psychopharmacological treatment of aggression has changed dramatically owing to the introduction of atypical antipsychotics on the market and the increased use of anticonvulsants and lithium in the treatment of aggressive patients.This review (second of 2 parts) uses a translational medicine approach to examine the neurobiology of aggression, discussing the major neurotransmitter systems implicated in its pathogenesis (serotonin, glutamate, norepinephrine, dopamine, and γ-aminobutyric acid) and the neuropharmacological rationale for using atypical antipsychotics, anticonvulsants, and lithium in the therapeutics of aggressive behavior. A critical review of all clinical trials using atypical antipsychotics (aripiprazole, clozapine, loxapine, olanzapine, quetiapine, risperidone, ziprasidone, and amisulpride), anticonvulsants (topiramate, valproate, lamotrigine, and gabapentin), and lithium are presented. Given the complex, multifaceted nature of aggression, a multifunctional combined therapy, targeting different receptors, seems to be the best strategy for treating aggressive behavior. This therapeutic strategy is supported by translational studies and a few human studies, even if additional randomized, double-blind, clinical trials are needed to confirm the clinical efficacy of this framework.

Abstract
Background and Purpose Levetiracetam (LEV) is a new antiepileptic drug that has been found to be effective as an adjunctive therapy for uncontrolled partial seizures. However, the results of several studies suggested that LEV has negative psychotropic effects, including irritability, aggressiveness, suicidality, and mood disorders. We investigated the impact of adjunctive LEV on psychiatric symptoms and quality of life (QOL) in patients with drug-refractory epilepsy (DRE) and determined the risk factors provoking psychiatric adverse events. Methods A 24-week, prospective, open-label study was conducted. At enrollment, we interviewed patients and reviewed their medical charts to collect demographic and clinical information. They were asked to complete self-report health questionnaires designed to measure various psychiatric symptoms and QOL at enrollment and 24 weeks later. Results Seventy-one patients were included in the study, 12 patients (16.9%) of whom discontinued LEV therapy due to serious adverse events including suicidality. The risk factor for premature withdrawal was a previous history of psychiatric diseases (odds ratio 4.59; 95% confidence interval, 1.22-17.32). LEV intake resulted in significant improvements in Beck Anxiety Inventory score (p<0.01) and some domains of the Symptom Checklist-90-Revised, such as somatization (p<0.05), obsessive-compulsiveness (p<0.05), depression (p<0.05), and anxiety (p<0.05). These improvements were not related to the occurrence of seizure freedom. The Quality of Life in Epilepsy Inventory-31 overall score and subscale scores, such as seizure worry (p<0.01), overall QOL (p<0.05), emotional well-being (p<0.05), energy-fatigue (p<0.05), and social function (p<0.05), also improved. Conclusions Adjunctive LEV in patients with DRE is likely to improve psychiatric symptoms and QOL. Clinicians should be well aware of the psychiatric histories of patients to prevent them from developing serious adverse events related to LEV.

Abstract
Aggression in patients with temporal lobe epilepsy (TLE) may have phenomenological and neurobiological heterogeneity. In the present study, we targeted patients with TLE who showed aggression and evaluated the effects of lamotrigine on this symptom using the Buss-Perry Aggression Questionnaire (BAQ), which is based on a four-factor model that includes Physical Aggression, Verbal Aggression, Anger, and Hostility. As compared with the healthy control subjects (n=115), patients with TLE (n=21) had significantly higher BAQ Total, Physical Aggression, Anger, and Hostility scores. Ten weeks after initiation of lamotrigine, the BAQ Total and Anger scores of the patients with TLE were significantly improved. However, the patients with TLE in this study did not exhibit depressive symptoms. Our results suggest that lamotrigine mitigates aggression, especially anger, which represents the emotional factor of aggression in the BAQ.

Abstract
The clinical interface between psychiatry and neurology is epilepsy; the pharmacological expression of this interface is antiepileptic drugs (AEDs), as they are used to treat both epilepsy and psychiatric disorders, especially bipolar disorders. The prevalence of psychiatric comorbidity and the risk of suicidal behavior/ideation/suicide are markedly increased in patients with epilepsy (PWE). Though AEDs receive initial indications for the treatment of epilepsy, currently the majority of AEDs are used to treat pain and psychiatric disorders. Thus in selecting the appropriate AEDs for treatment of PWE, consideration should be given to which AEDs best treat the epileptic disorder and the psychiatric comorbidity. This review is an overview of 21 AEDs in which negative psychotropic properties, approved indications in psychiatry, off-label studied uses in psychiatry, and principal uses in psychiatry are presented with literature review. A total of 40 psychiatric uses have been identified. Of the 21 AEDs reviewed, only 5 have U.S. Food and Drug Administration and/or European Medicines Agency psychiatric approval for limited uses; the majority of AEDs are used off-label. Many of these off-label uses are based on case reports, open-label studies, and poorly controlled or small-sample-size studies. In some instances, off-label use persists in the face of negative pivotal trials. Further placebo-controlled (augmentation and monotherapy) parallel-arm research with active comparators is required in the complex field of AED treatment of psychiatric disorders to minimize the treatment gap not only for PWE with psychiatric disorders, but also for psychiatric patients who would benefit from properly studied AEDs while minimizing adverse effects.

Abstract
The purpose of this study was to investigate the relationships among medicine symptom distress, self-efficacy, patient-provider relationship, and medication compliance in patients with epilepsy. Patients with epilepsy (n=357) were recruited using convenience sampling from three medical centers in northern Taiwan. Results showed significant differences in relationships between medication compliance and the following factors: gender, employment status, comorbid chronic diseases, self-driving, daily drug dosing frequency, seizure after a missed dose, and self-efficacy. Logistic regression analysis indicated that comorbid chronic disease, self-driving, seizure after a missed dose, and self-efficacy were significantly associated with medication compliance. These data suggest that health care providers of patients with epilepsy pay more attention to treatment of comorbid chronic diseases, the safety issues of self-driving, seizures occurring after missed doses, and awareness of self-efficacy.

Abstract
Lamotrigine (LTG), an anticonvulsive drug, is often used for the treatment of a variety of epilepsies. In addition to block of sodium channels, LTG may act on other targets to exert its antiepileptic effect. In the present study, we evaluated the effects of LTG on neuronal nicotinic acetylcholine receptors (nAChRs) using the patch-clamp technique on human α4β2-nAChRs heterologously expressed in the SH-EP1 cell line and on native α4β2-nAChRs in dopaminergic (DA) neurons in rat ventral tegmental area (VTA). In SH-EP1 cells, LTG diminished the peak and steady-state components of the inward α4β2-nAChR-mediated currents. This effect exhibited concentration-, voltage- and use-dependent behavior. Nicotine dose-response curves showed that in the presence of LTG, the nicotine-induced maximal current was reduced, suggesting a noncompetitive inhibition. These findings suggest that LTG inhibits human neuronal α4β2-nAChR function through an open-channel blocking mechanism. LTG-induced inhibition in α4β2-nAChRs was more profound when preceded by a 2-min pretreatment, after which the nicotine-induced current was reduced even without coapplication of LTG, suggesting that LTG is also able to inhibit α4β2-nAChRs without channel activation. In freshly dissociated VTA DA neurons, LTG inhibited α4β2-nAChR-mediated currents but did not affect glutamate- or GABA-induced currents, indicating that LTG selectively inhibits nAChR function. Collectively, our data suggest that the neuronal α4β2-nAChR is likely an important target for mediating the anticonvulsive effect of LTG and the blockade of α4β2-nAChR possibly underlying the mechanism through which LTG effectively controls some types of epilepsy, such as autosomal dominant nocturnal frontal lobe epilepsy or juvenile myoclonic epilepsy.

Abstract
Selecting an antiepileptic drug (AED) for treatment of seizures is daunting because there are now 20 from which to choose. Following simple principles allows a systematic approach to drug selection. Efficacy studies provide limited information. For initial monotherapy of partial seizures, high-level evidence exists for the efficacy of lamotrigine, carbamazepine, oxcarbazepine, and topiramate. For initial monotherapy of generalized seizures, high-level evidence is available for valproate, lamotrigine, topiramate, and oxcarbazepine. For initial monotherapy of absence seizures, high-level evidence exists for valproate, lamotrigine, and ethosaximide. All second-generation AEDs have efficacy as adjunctive therapy for partial seizures. AEDs are often useful for comorbid conditions or have properties that should be avoided in some groups. Thus, AEDs should usually be selected on the basis of comorbid conditions, including depression, migraine, chronic pain, obesity, and nephrolithiasis, or patient characteristics, especially for women of childbearing potential and older adults.

Abstract
OBJECTIVE Medical conditions and associated procedures/treatments may impact therapeutic blood levels of pharmacologic agents in the illnesses we treat. The use of anti-epileptic drugs in the treatment of psychiatric disorders, most commonly bipolar disorders, and epilepsy is a case in point. This report addresses the impact of hemodialysis on lamotrigine efficacy in bipolar disorder. METHOD Case analysis with literature review. RESULTS A bipolar disorder patient stabilized on lamotrigine 200 mg total daily dose was admitted to the hospital with end-stage renal disease. With three consecutive days of hemodialysis, treatment-emergent hypomanic features were noted by the patient and confirmed in psychiatric consultation. When lamotrigine was increased to 250 mg total daily dose, the bipolar features remitted. CONCLUSION Lamotrigine titration may be required in bipolar disorder patients undergoing hemodialysis secondary to the associated hemodialysis extraction factor. Therapeutic drug monitoring is recommended in these patients.

Abstract
BACKGROUND Aggression is a major public health issue and is integral to several mental health disorders. Antiepileptic drugs may reduce aggression by acting on the central nervous system to reduce neuronal hyper-excitability associated with aggression. OBJECTIVES To evaluate the efficacy of antiepileptic drugs in reducing aggression and associated impulsivity. SEARCH STRATEGY We searched CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, metaRegister of Controlled Trials (mRCT) and ClinicalTrials.gov to April 2009. We also searched Cochrane Schizophrenia Group's register of trials on aggression, National Research Record and handsearched for studies. SELECTION CRITERIA Prospective, placebo-controlled trials of antiepileptic drugs taken regularly by individuals with recurrent aggression to reduce the frequency or intensity of aggressive outbursts. DATA COLLECTION AND ANALYSIS Three authors independently selected studies and two authors independently extracted data. We calculated standardised mean differences (SMDs), with odds ratios (ORs) for dichotomous data. MAIN RESULTS Fourteen studies with data from 672 participants met the inclusion criteria. Five different antiepileptic drugs were examined. Sodium valproate/divalproex was superior to placebo for outpatient men with recurrent impulsive aggression, for impulsively aggressive adults with cluster B personality disorders, and for youths with conduct disorder, but not for children and adolescents with pervasive developmental disorder. Carbamazepine was superior to placebo in reducing acts of self-directed aggression in women with borderline personality disorder, but not in children with conduct disorder. Oxcarbazepine was superior to placebo for verbal aggression and aggression against objects in adult outpatients. Phenytoin was superior to placebo on the frequency of aggressive acts in male prisoners and in outpatient men including those with personality disorder, but not on the frequency of 'behavioral incidents' in delinquent boys. AUTHORS' CONCLUSIONS The authors consider that the body of evidence summarised in this review is insufficient to allow any firm conclusion to be drawn about the use of antiepileptic medication in the treatment of aggression and associated impulsivity. Four antiepileptics (valproate/divalproex, carbamazepine, oxcarbazepine and phenytoin) were effective, compared to placebo, in reducing aggression in at least one study, although for three drugs (valproate, carbamazepine and phenytoin) at least one other study showed no statistically significant difference between treatment and control conditions. Side effects were more commonly noted for the intervention group although adverse effects were not well reported. Absence of information does not necessarily mean that the treatment is safe, nor that the potential gains from the medication necessarily balance the risk of an adverse event occurring. Further research is needed.

Abstract
A 27-year-old woman presented to the emergency room after having witnessed generalized tonic clonic seizure while asleep. Birth and development were normal. She had suffered a single febrile seizure at 13 months of age, but had no other seizure risk factors. She was otherwise well except for a history of depression for which she was taking sertraline. Depressive symptoms had been well controlled over the past 3 months, but she had been under increased stress working to finish a doctoral thesis. Neurological examination was normal. Magnetic resonance imaging (MRI) showed modest asymmetry of the hippocampi, slightly smaller on the right, but no abnormal signal and well-preserved laminar anatomy. An electroencephalogram was negative. She was discharged from the emergency room with no treatment. Three weeks later, the patient's boyfriend witnessed an episode of behavioral arrest with lip smacking and swallowing automatisms lasting 45 seconds, after which the patient was confused for 20–30 minutes. The next morning she and her boyfriend kept a previously scheduled appointment with a neurologist.

Abstract
Epilepsy affects approximately 50 million people worldwide, with an annual incidence of 50 to 70 cases per 100,000 population. The condition can strike at any time of life, with an immediate impact on everyday activities and routine. Key to optimal management is swift referral to an epilepsy specialist, appropriate investigation, and timely institution of antiepileptic drug therapy. In the past 20 years, the explosion of 13 new agents into the marketplace has greatly increased the potential for therapeutic intervention. This article explores the rationale for treatment selection in adults with epilepsy.
