King FK, Perry MS, Papadelis C, Cooper CM. Spatiotemporal responses to emotional conflict and its psychiatric correlates in adolescents with epilepsy using magnetoencephalography. Epilepsy Behav 2024; 157:109869. [PMID: 38851125 DOI: 10.1016/j.yebeh.2024.109869] [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: 03/12/2024] [Revised: 05/26/2024] [Accepted: 05/27/2024] [Indexed: 06/10/2024]
Abstract
People with epilepsy often suffer from comorbid psychiatric disorders, which negatively affects their quality of life. Emotion regulation is an important cognitive process that is impaired in individuals with psychiatric disorders, such as depression. Adults with epilepsy also show difficulties in emotion regulation, particularly during later-stage, higher-order cognitive processing. Yet, the spatiotemporal and frequency correlates of these functional brain deficits in epilepsy remain unknown, as do the nature of these deficits in adolescent epilepsy. Here, we aim to elucidate the spatiotemporal profile of emotional conflict processing in adolescents with epilepsy, relative to controls, using magnetoencephalography (MEG) and relate these findings to anxiety and depression symptom severity assessed with self-report scales. We hypothesized to see blunted brain activity during emotional conflict in adolescents with epilepsy, relative to controls, in the posterior parietal, prefrontal and cingulate cortices due to their role in explicit and implicit regulation around participant response (500-1000 ms). We analyzed MEG recordings from 53 adolescents (28 epilepsy [14focal,14generalized], 25 controls) during an emotional conflict task. We showed that while controls exhibited behavioral interference to emotional conflict, adolescents with epilepsy failed to exhibit this normative response time pattern. Adolescents with epilepsy showed blunted brain responses to emotional conflict in brain regions related to error evaluation and learning around the average response time (500-700 ms), and in regions involved in decision making during post-response monitoring (800-1000 ms). Interestingly, behavioral patterns and psychiatric symptom severity varied between epilepsy subgroups, wherein those with focal epilepsy showed preserved response time interference. Thus, brain responses were regressed with depression and anxiety levels for each epilepsy subgroup separately. Analyses revealed that under activation in error evaluation regions (500-600 ms) predicted anxiety and depression in focal epilepsy, while regions related to learning (600-700 ms) predicted anxiety in generalized epilepsy, suggesting differential mechanisms of dysfunction in these subgroups. Despite similar rates of anxiety and depression across the groups, adolescents with epilepsy still exhibited deficits in emotional conflict processing in brain and behavioral responses. This suggests that these deficits may exist independently from psychopathology and may stem from underlying dysfunctions that predispose these individuals to develop both disorders. Findings such as these may provide potential targets for future research and therapies.

Antiepileptogenic Effects of Anakinra, Lamotrigine and Their Combination in a Lithium-Pilocarpine Model of Temporal Lobe Epilepsy in Rats. Int J Mol Sci 2023; 24:15400. [PMID: 37895080 PMCID: PMC10607594 DOI: 10.3390/ijms242015400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Revised: 10/17/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
Temporal lobe epilepsy is a common, chronic disorder with spontaneous seizures that is often refractory to drug therapy. A potential cause of temporal lobe epilepsy is primary brain injury, making prevention of epileptogenesis after the initial event an optimal method of treatment. Despite this, no preventive therapy for epilepsy is currently available. The purpose of this study was to evaluate the effects of anakinra, lamotrigine, and their combination on epileptogenesis using the rat lithium-pilocarpine model of temporal lobe epilepsy. The study showed that there was no significant difference in the number and duration of seizures between treated and untreated animals. However, the severity of seizures was significantly reduced after treatment. Anakinra and lamotrigine, alone or in combination, significantly reduced neuronal loss in the CA1 hippocampus compared to the control group. However, the drugs administered alone were found to be more effective in preventing neuron loss in the hippocampal CA3 field compared to combination treatment. The treatment alleviated the impairments in activity level, exploratory behavior, and anxiety but had a relatively weak effect on TLE-induced impairments in social behavior and memory. The efficacy of the combination treatment did not differ from that of anakinra and lamotrigine monotherapy. These findings suggest that anakinra and lamotrigine, either alone or in combination, may be clinically useful in preventing the development of histopathological and behavioral abnormalities associated with epilepsy.

Abstract
Epilepsy is a common condition worldwide, with approximately 50 million people suffering from it. A single seizure does not mean epilepsy; almost 10% of the population can have a seizure during their lifetime. In particular, there are many other central nervous system disorders other than epilepsy in which seizures occur, either transiently or as a comorbid condition. The impact of seizures and epilepsy is, therefore, widespread and easily underestimated. It is estimated that about 70% of patients with epilepsy could be seizure-free if correctly diagnosed and treated. However, for patients with epilepsy, quality of life is influenced not only by seizure control but also by antiepileptic drug-adverse reactions, access to education, mood, employment, and transportation.

Abstract
Epilepsy treatment with antiepileptic drugs (AEDs) is usually requires for many years. Q808 is an innovative antiepileptic chemical. It exerts effective antiepileptic effect against various epilepsy models. Exploring the gene transcriptomic profile of long-term treatment of Q808 is necessary. In the present study, hippocampus RNA-sequencing was performed to reveal the transcriptome profile of rats before and after treatment of Q808 for 28 days. Results confirmed 51 differentially expressed genes (DEGs) between Q808 and healthy control groups. Gene cluster analysis showed that most upregulated DEGs linked to response to drug and nucleus, most downregulated DEGs linked to locomotory, neuronal cell body, and drug binding. Most of DEGs were enriched in the signaling transduction, substance dependence, nervous system, and neurodegenerative disease pathways. Furthermore, quantitative real-time PCR analysis confirmed that Q808 significantly increased the expression of neuroprotective genes, such as Mdk, and decreased the mRNA levels of Penk, Drd1, and Adora2a, which are highly expressed in epilepsy models. In addition, Q808 decreased the mRNA expression of Pde10A and Drd2, which are known to be closely associated with schizophrenia. Our study may provide a theoretical basis to explore the effect of Q808 on the susceptibility to epilepsy and other neurological diseases.

Abstract
Aims This multicenter, open‐label, randomized study (Registration No. ChiCTR‐OCH‐14004528) aimed to compare the efficacy and effects of oxcarbazepine (OXC) with levetiracetam (LEV) as monotherapies on patient quality of life and mental health for patients with newly diagnosed focal epilepsy from China. Methods Patients with newly diagnosed focal epilepsy who had experienced 2 or more unprovoked seizures at greater than a 24‐h interval during the previous year were recruited. Participants were randomly assigned to the OXC group or LEV group. Efficacy, safety, quality of life, and mental health were evaluated over 12‐week and 24‐week periods. Results In total, we recruited 271 newly diagnosed patients from 23 centers. Forty‐four patients were excluded before treatment for reasons. The rate of seizure freedom of OXC was significantly superior to that of LEV at 12 weeks and 24 weeks (p < 0.05). The quality of life (except for the seizure worry subsection) and anxiety scale scores also showed significant differences from before to after treatment in the OXC and LEV groups. Conclusions OXC monotherapy may be more effective than LEV monotherapy in patients with newly diagnosed focal epilepsy. Both OXC and LEV could improve the quality of life and anxiety state in adult patients with focal epilepsy.

Abstract
Although depressive symptoms are the most common psychiatric comorbidity in epilepsy, they remain underestimated and untreated in a large proportion of patients. The purpose of this study was to evaluate depression severity and related clinical features in people with epilepsy using a well-reliable self-report index of mood, the Beck Depression Inventory-II (BDI-II). One-hundred seventeen adult patients with epilepsy were recruited from a tertiary epilepsy center and completed the BDI-II. A single-item analysis of the 21 questions of the BDI-II was computed and differences between women and men in each depressive symptom were evaluated. Correlation and regression analyses were used to identify clinical features associated with the severity of depression. Results showed gender differences in some items, with women reporting overall higher depression severity than men. The most common symptoms regarded domains of sleeping patterns, tiredness, and loss of energy. Regression evidence suggested that being female, having an epilepsy duration < 10 years, as well as being treated with psychotropic drugs and reporting generalized seizure, were associated with higher depression severity. Despite its cross-sectional nature, this study reinforces the importance of investigating and possibly treating depressive symptoms in adult patients with epilepsy, since they negatively impact well-being, daytime activities, and sleep. Further studies identifying pharmacological and non-pharmacological treatments for depression in epilepsy need to be planned.

Abstract
BACKGROUND Dilated cardiomyopathy (DCM) in children is an important cause of severe heart failure and carries a poor prognosis. Adults with heart failure are at increased risk of anxiety and depression and such symptoms predict adverse clinical outcomes such as mortality. In children with DCM, studies examining these associations are scarce. AIMS We studied whether in children with DCM: (1) the level of emotional and behavioral problems was increased as compared to normative data, and (2) depressive and anxiety problems were associated with the combined risk of death or cardiac transplantation. METHODS To assess emotional and behavioral problems in children with DCM, parents of 68 children, aged 1.5-18 years (6.9±5.7 years), completed the Child Behavior Checklist. RESULTS Compared to normative data, more young children (1.5-5 years) with DCM had somatic complaints (24.3% vs. 8.0%; p < .001), but fewer had externalizing problems (5.4% vs. 17.0%; p = .049). Overall internalizing problems did not reach significance. Compared to normative data, more older children (6-18 years) showed internalizing problems (38.7% vs. 17.0%; p = .001), including depressive (29.0% vs. 8.0%; p < .001) and anxiety problems (19.4% vs. 8.0%; p = .023), and somatic complaints (29.0% vs. 8.0%; p < .001). Anxiety and depressive problems, corrected for heart failure severity, did not predict the risk of death or cardiac transplantation. CONCLUSION Children of 6 years and older showed more depressive and anxiety problems than the normative population. Moreover, in both age groups, somatic problems were common. No association with outcome could be demonstrated.

Abstract
PURPOSE OF REVIEW For patients living with epilepsy, quality of life is determined not only by seizure control but by mood, antiepileptic drug adverse effects, relationships, and access to education, employment, and transportation. This article reviews some of the most commonly encountered concerns associated with epilepsy, including mood disorders, driving, injuries, mortality, bone health, genetic burden, and impact on relationships. RECENT FINDINGS People with epilepsy are at increased risk for anxiety, depression, and suicide. Depression is underrecognized in patients with epilepsy, but effective validated screening tools are available for use. Mortality rates for people with epilepsy are 2 times higher than those of the general population, but much of this is attributable to underlying conditions rather than seizures. Sudden unexpected death in epilepsy (SUDEP) occurs in an estimated 1:1000 adults with epilepsy per year, and the risk can be reduced by improved observation and seizure control. An increased risk of injury, including fractures, is also present in patients with epilepsy. Reduced bone health leading to increased fracture risk is an important negative consequence of long-term use of antiepileptic medication. Seizures while driving can also cause accidents and injury. Despite the importance of driving for people with epilepsy, physicians are underperforming in providing counsel about driving. SUMMARY Optimal care of the patient with epilepsy includes addressing risks to emotional health, physical health including fractures and SUDEP, social health, and an independent lifestyle. Identification of and treatments to reduce these risks can do more to improve quality of life than a narrow clinical focus on seizure control alone.

Ethosuximide improves chronic pain-induced anxiety- and depression-like behaviors. Eur Neuropsychopharmacol 2019; 29:1419-1432.

Abstract
Chronic pain is a heavy burden disease. Current treatments are generally weakly effective or associated with adverse effects. New therapeutic approaches are therefore needed. Recent studies have suggested T-type calcium channels as an attractive target for the treatment of chronic pain. In this perspective, it was decided to perform a preclinical evaluation of the efficacy of ethosuximide, a T-type channel blocker used clinically as an antiepileptic, as a novel pharmacological treatment for chronic pain. Assessment of the effect of ethosuximide was thus made in both nociception and pain-related comorbidities as anxiety and depression are frequently encountered in chronic pain patients. Our results show that such symptoms occurred in three animal models of chronic pain designed to reflect traumatic neuropathic, chemotherapy-induced neuropathic and inflammatory pain conditions. Administration of ethosuximide reduced both chronic pain and comorbidities with a marked intensity ranging from partial reduction to a complete suppression of symptoms. These results make ethosuximide, and more broadly the inhibition of T-type calcium channels, a new strategy for the management of uncontrolled chronic pain, likely to improve not only pain but also the accompanying anxiety and depression.

Abstract
Persons with epilepsy show a higher risk of suicidal ideation and behavior than the general population. Hopelessness, as a feature of demoralization, is considered an emerging risk factor for suicidal ideation. Psychopathological comorbidity, mainly depression, has to be taken into account to predict suicidal attempts but the relationship between suicidality and epilepsy has been also reported independently from depressive disorders. The aim of the study was to investigate hopelessness in a sample of persons suffering from epilepsy without comorbidity with psychiatric disorders and its association with demographic, social, and clinical variables, putatively predictive of suicidal behaviors. Beck Hopelessness Scale (BHS) has been used as measure of suicidal ideation in 72 consecutive outpatients afferent to a third level epilepsy center. Exclusion criterion was psychiatric comorbidity evaluated by clinical approach and quantified by Clinical Global Impression (CGI) Scale. Clinical (focus localization, age at onset, number of drugs), demographic, social variables, and intellectual level were considered. Age, age at onset, gender, intellectual level, socioeconomic status, duration of illness and therapy, number of drugs, seizure frequency, and localization of the epileptic focus and side involved were found associated with BHS score increase. In a sample of persons with epilepsy, without psychiatric comorbidity, our data show an association between factors related to the biological pathophysiology and the clinical course of the disease with the sociodemographic status, as a risk factor for suicidal ideation.

[PMID: 31234043 DOI: 10.1016/j.yebeh.2019.06.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Revised: 06/01/2019] [Accepted: 06/02/2019] [Indexed: 01/18/2023]
Abstract
OBJECTIVE The major cause of premature mortality in people with epilepsy (PWE) is suicide. Actual data on the risk of suicidal tendency in adult PWE in China are scarce. In our study, associations between possible risk factors and suicidal tendency in adult PWE in China were investigated. METHODS People with epilepsy (n = 251) were recruited, and their demographic and clinical characteristics were evaluated. Suicide risk was examined using the suicidality module (SM) of the Mini International Neuropsychiatric Interview (MINI) Plus Chinese Version 5.0.0. RESULTS Suicidal tendency was present in 36 (14.3%) of the 251 PWE. On the basis of the results of univariate analyses, family relationship (P < 0.001), age at epilepsy onset (P = 0.037), seizure-free period (P = 0.041), seizures/month (P = 0.015), depressive disorders (P < 0.001), and number of antiepileptic drugs (AEDs) (P = 0.017) were associated with suicidal tendency. Multivariate analysis revealed that moderate or poor family relationships (odds ratio (OR): 6.468, 95% confidence interval (CI): 2.418-17.300) and depressive disorders (OR: 3.548, 95% CI: 1.575-7.995) were associated with high odds of suicidal tendency. CONCLUSION Suicidal tendency is common among adult PWE. This study reveals that family relationships and depressive disorders are independent risk factors for suicidal tendency among adult PWE. Therefore, while maintaining treatment of epilepsy, more attention should be directed to the social support and mental state of PWE to prevent suicide.

Abstract
The administration of antiepileptic drugs (AEDs) is the first treatment of epilepsy, one of the most common neurological diseases. Therapeutic guidelines include newer AEDs as front-line drugs; monotherapy with new AEDs is delivered in Japan. While about 70% of patients obtain good seizure control by taking one to three AEDs, about 60% experience adverse effects and 33% have to change drugs. Compared to traditional AEDs, the prolonged administration of new AEDs elicits fewer adverse effects and fewer drug interactions and their teratogenicity may be lower. These characteristics increase drug compliance and allow combination therapy for drug-resistant epilepsy, although the antiepileptic effects of the new AEDs are not greater than of traditional AEDs. Comorbidities are not rare in epileptics; many adult patients present with stroke and brain tumors. In stroke patients requiring risk control and in chemotherapy-treated brain tumor patients, their fewer drug interactions render the new AEDs advantageous. Also, new AEDs offer favorable side benefits for concurrent diseases and conditions. Patients with stroke and traumatic brain injury often present with psychiatric/behavioral symptoms and cognitive impairment and some new AEDs alleviate such symptoms. This review presents an outline of the new AEDs used to treat adult patients based on the pharmacological activity of the drugs and discusses possible clinical indications from the perspective of underlying causative diseases and comorbidities.

Abstract
Mood disorders are among the major health problems that exist worldwide. They are highly prevalent in the general population and cause significant disturbance of life quality and social functioning of the affected persons. The two major classes of mood disorders are bipolar disorders and depression. The latter is assumed to be the most frequent psychiatric comorbidity in epilepsy. Studies published during the second half of the 20th century recognized that certain patients with epilepsy present a depressed mood. Synthesized pharmaceuticals have been in use for decades to treat both mood disorders and epilepsy, but despite their efficiency, their use is limited by numerous side effects. On the other hand, animal models have been developed to deeply study potential botanicals which have an effect on mood disorders. Studies to investigate the potential effects of medicinal plants acting on the nervous system and used to treat seizures and anxiety are increasingly growing. However, these studies discuss the two conditions separately without association. In this review, we present animal models of depression and investigative models (methods of assessing depression) of depression and anxiety in animals. Other classical test models for prediction of clinical antidepressant activity are presented. Finally, this review also highlights antidepressant activities of herbals focusing specially on depression-like behaviors associated with epilepsy. The pharmacological properties and active principles of cited medicinal plants are emphasized. This review, therefore, provides an overview of the work done on botanicals for mood disorders, potential mechanisms of action of botanicals, and the major compounds. This article is part of a Special Issue entitled "Botanicals for Epilepsy".

Abstract
OBJECTIVE To compare quality-of-life (QoL) outcomes over 2 years following initiation of treatment with a standard or newer antiepileptic drug (AED) in adults with new-onset epilepsy. To examine the impact of seizure remission and failure of initial treatment on QoL outcomes measured over 2 years. METHODS We conducted a pragmatic, randomized, unblinded, multicenter, parallel-group clinical trial (the Standard and New Antiepileptic Drugs [SANAD] trial) comparing clinical and cost effectiveness of initiating treatment with carbamazepine versus lamotrigine, gabapentin, oxcarbazepine and topiramate, and valproate versus lamotrigine and topiramate. QoL data were collected by mail at baseline, 3 months, and at 1 and 2 years using validated measures. These data were analyzed using longitudinal data models. Continuous QoL measures, time to 12-month remission and time to treatment withdrawal were explored using joint models. RESULTS Baseline questionnaires were returned by 1,575 adults; 1,439 returned the 3-month questionnaire, 1,274 returned the 1-year questionnaire, and 1,121 returned the 2-year questionnaire. There were few statistically significant differences between drugs over 2 years in QoL outcomes. Significant association was identified between QoL scores over the 2-year time frame and the risk of experiencing a 12-month remission or treatment withdrawal over that period. SIGNIFICANCE The choice of initial treatment had no significant effect on QoL by 2-year follow-up. However, overall QoL was reduced with continued seizures, adverse events, and failure of the initial treatment.

Event-related potentials reveal preserved attention allocation but impaired emotion regulation in patients with epilepsy and comorbid negative affect. PLoS One 2015; 10:e0116817.

Abstract
Patients with epilepsy have a high prevalence of comorbid mood disorders. This study aims to evaluate whether negative affect in epilepsy is associated with dysfunction of emotion regulation. Event-related potentials (ERPs) are used in order to unravel the exact electrophysiological time course and investigate whether a possible dysfunction arises during early (attention) and/or late (regulation) stages of emotion control. Fifty epileptic patients with (n = 25) versus without (n = 25) comorbid negative affect plus twenty-five matched controls were recruited. ERPs were recorded while subjects performed a face- or house-matching task in which fearful, sad or neutral faces were presented either at attended or unattended spatial locations. Two ERP components were analyzed: the early vertex positive potential (VPP) which is normally enhanced for faces, and the late positive potential (LPP) that is typically larger for emotional stimuli. All participants had larger amplitude of the early face-sensitive VPP for attended faces compared to houses, regardless of their emotional content. By contrast, in patients with negative affect only, the amplitude of the LPP was significantly increased for unattended negative emotional expressions. These VPP results indicate that epilepsy with or without negative affect does not interfere with the early structural encoding and attention selection of faces. However, the LPP results suggest abnormal regulation processes during the processing of unattended emotional faces in patients with epilepsy and comorbid negative affect. In conclusion, this ERP study reveals that early object-based attention processes are not compromised by epilepsy, but instead, when combined with negative affect, this neurological disease is associated with dysfunction during the later stages of emotion regulation. As such, these new neurophysiological findings shed light on the complex interplay of epilepsy with negative affect during the processing of emotional visual stimuli and in turn might help to better understand the etiology and maintenance of mood disorders in epilepsy.

Abstract
Valproic acid and the antidepressants doxepin and venlafaxine are frequently used psychotropic drugs. In the literature, an influence of valproic acid on serum levels of antidepressants has been described, although studies have focused on amitriptyline. The authors assessed their therapeutic drug monitoring (TDM) database for patients receiving a combination of doxepin or venlafaxine and valproic acid and compared these samples with matched controls without valproic acid comedication in terms of the serum concentration of antidepressants. The mean dose-corrected serum concentration of doxepin+N-doxepin in 16 patients who received valproic acid comedication was higher (2.171±1.482 ng/ml/mg) than that in the matched controls (0.971±0.857 ng/ml/mg, P<0.003). We also found a significant correlation between valproic acid serum level and dose-corrected doxepin+N-doxepin serum level (Spearman's ρ r=0.602, P<0.014). The mean dose-corrected serum level of venlafaxine+O-desmethylvenlafaxine in 41 patients who received valproic acid comedication did not differ significantly from that of the matched controls (P<0.089), but there was a significant difference between both groups in the dose-corrected serum level of O-desmethylvenlafaxine (1.403±0.665 vs. 1.102±0.444, P<0.017). As a consequence, if a combination of valproic acid with doxepin or venlafaxine is administered, cautious dosing is advisable and TDM should be performed.

Abstract
BACKGROUND AND AIMS To investigate the relationships between demographic data, seizure-related factors, anti-epileptic drugs (AEDs) taking, and depressive symptoms in patients with epilepsy (PWE), determining the major clinical risk factors of depression. METHODS Patients with epilepsy who visited our epilepsy clinic from 2010 to 2012 were included. The clinical data were collected, and Hamilton Depression Rating Scale (HAMD), National Hospital Seizure Severity Scale (NHS3) and Pittsburgh Sleep Quality Index (PSQI) were evaluated. RESULTS A total of 116 PWE were recruited. They were divided into three groups. Age, duration of epilepsy, percentages of patients with partial seizures, history of status epilepticus (SE), using topiramate (TPM) or clonazepam (CZP), and using greater than or equal to 2 types of AEDs were all significantly higher in patients with moderate depressive symptoms than patients without depression. HAMD scores were positively correlated with age, duration of epilepsy, and the number of AEDs taking, respectively. PSQI scores were positively correlated with HAMD scores in patients with depressive symptoms. Age greater than 35 years, females, having partial seizures, history of SE, and using TPM were independent predictors of depressive symptoms in PWE by regression analysis. CONCLUSIONS Age greater than 35 years, females, having partial seizures, history of SE, and using TPM might become risk factors for depressive symptoms in PWE.

Abstract
Depressive syndromes represent a common and often characteristic feature in a number of neurological disorders. One prominent example is the development of post-stroke depression, which can be observed in more than one-third of stroke survivors in the aftermath of an ischemic stroke. Thus, post-stroke depression represents one of the most prevalent, disabling, and potentially devastating psychiatric post-stroke complications. On the other hand, depressive syndromes may also be considered as a risk factor for certain neurological disorders, as recently revealed by a meta-analysis of prospective cohort studies, which demonstrated an increased risk for ischemic events in depressed patients. Moreover, depressive syndromes represent common comorbidities in a number of other neurological disorders such as Parkinson's disease, multiple sclerosis, or epilepsy, in which depression has a strong impact on both quality of life and outcome of the primary neurological disorder.

Abstract
Temporal lobe epilepsy (TLE) is typically described as a neurologic disorder affecting a cerebral network comprising the hippocampus proper and several anatomically related extrahippocampal regions. A new level of complexity was recently added to the study of this disorder by the evidence that TLE also appears to chronically alter the activity of several brain-wide neural networks involved in the control of higher order brain functions and not traditionally linked to epilepsy. Recently developed brain imaging techniques such as functional magnetic resonance imaging (fMRI) analysis of resting state connectivity, have greatly contributed to these observations by allowing the precise characterization of several brain networks with distinct functional signatures in the resting brain, and therefore also known as "resting state networks." These significant advances in imaging represent an opportunity to investigate the still elusive origins of the disabling cognitive and psychiatric manifestations of TLE, and could have important implications for its pathophysiology and, perhaps, its therapy. Herein we review recent studies in this field by focusing on resting state networks that have been implicated in the pathophysiology of psychiatric disorders and cognitive impairment in patients with epilepsy: the default mode network, the attention network, and the reward/emotion network.

Abstract
Although medications such as anticancer, antimicrobial, immunomodulatory, neurological or hormonal therapies may have a negative impact on mood, adequate attention was not paid until the withdrawal of rimonabant in 2008. In the present study the authors review full spectrum of currently available medications discussing anxiety and depression as possible adverse effects of treatment. A relatively high risk of depression should always be considered when pharmacotherapy applied, especially if current depressive episodes, positive family history, or neurotic personality traits increasing susceptibility to depressogenic effects. Prior to start of medical treatment, the potential effectiveness of the given drug should be precisely evaluated, and alternative medical and non-medical treatment options should also be carefully considered. In addition, monitoring patients during treatment for signs of depressive or anxious symptoms is necessary.

Abstract
Amitriptyline (AMI) and valproic acid (VPA) are common psychotropic drugs which are frequently used in psychiatry and also administered in neurology or anesthesia in the absence of a psychiatric indication. On the basis of the case of a 73-year-old man with therapy-resistant major depressive episode who experienced anticholinergic delirium after adding VPA to AMI, we retrospectively analyzed therapeutic drug monitoring data of the years 2008 to 2010. We assessed cases receiving a combination of AMI and VPA, and obtained a control sample of AMI patients without VPA which were matched for sex, age, daily dose, and comedication. Both samples were compared regarding the serum levels of AMI and nortriptyline (NOR) as well as the ratio of NOR and AMI with the Mann-Whitney U test. The combination of AMI and VPA led to a remarkable increase of AMI and NOR serum levels. When comparing 33 patients who received comedication with VPA versus 33 matched controls, the total concentration by combining mean AMI and NOR serum levels (237.1 [119.9] vs 126.4 [52.8] ng/mL) and NOR/AMI ratio (1.300 [0.905] vs 0.865 [0.455]) was significantly higher. Both AMI and VPA are widely prescribed drugs. A combination of both is common for psychiatric or neurologic patients. A cautious dosing of AMI with VPA comedication is advisable, and therapeutic drug monitoring should be performed because this combination may lead to a remarkable increase of AMI and NOR serum levels.

Abstract
Antiepileptic drugs (AEDs) are used by millions of people worldwide for the treatment of epilepsy, as well as in many other neurological and psychiatric conditions. They are frequently associated with adverse effects (AEs), which have an impact on the tolerability and success of treatment. Half the people who develop intolerable AEs discontinue treatment early on after initiation, while the majority of people will continue to be exposed to their effects for long periods of time. The long-term safety of AEDs reflects their potential for chronic, cumulative dose effects; rare, but potentially serious late idiosyncratic effects; late, dose-related effects; and delayed, teratogenic or neurodevelopmental effects. These AEs can affect every body system and are usually insidious. With the exception of delayed effects, most other late or chronic AEs are reversible. To date, there is no clear evidence of a carcinogenic effect of AEDs in humans. While physicians are aware of the long-term AEs of old AEDs (the traditional liver enzyme-inducing AEDs and valproate), information about AEs of new AEDs (such as lamotrigine, levetiracetam, oxcarbazepine, topiramate or zonisamide), particularly of their teratogenic effects, has emerged over the years. Sporadic publications have raised issues about AEs of the newer AEDs eslicarbazepine, retigabine, rufinamide, lacosamide and perampanel but their long-term safety profiles may take years to be fully appreciated. Physicians should not only be aware of the late and chronic AEs of AEDs but should systematically enquire and screen for these according to the individual AED AE profile. Care should be taken for individuals with comorbid conditions that may render them more susceptible to specific AEs. Prevention and appropriate management of long-term AED AEs is expected to improve adherence to treatment, quality of life and control of epilepsy.

Abstract
OBJECTIVE There is accumulating evidence that the limbic system is pathologically involved in cases of psychiatric comorbidities in temporal lobe epilepsy (TLE) patients. Our objective was to develop a conceptual framework describing how neuropathological, neurochemical and electrophysiological aspects might contribute to the development of psychiatric symptoms in TLE and the putative neurobiological mechanisms that cause mood disorders in this patient subgroup. METHODS In this review, clinical, experimental and neuropathological findings, as well as neurochemical features of the limbic system were examined together to enhance our understanding of the association between TLE and psychiatric comorbidities. Finally, the value of animal models in epilepsy and mood disorders was discussed. CONCLUSIONS TLE and psychiatric symptoms coexist more frequently than chance would predict. Alterations and neurotransmission disturbance among critical anatomical networks, and impaired or aberrant plastic changes might predispose patients with TLE to mood disorders. Clinical and experimental studies of the effects of seizures on behavior and electrophysiological patterns may offer a model of how limbic seizures increase the vulnerability of TLE patients to precipitants of psychiatric symptoms.

Abstract
In many neurological diseases a depressive syndrome is a characteristic sign of the primary disease or is an important comorbidity. Post-stroke depression, for example, is a common and relevant complication following ischemic brain infarction. Approximately 4 out of every 10 stroke patients develop depressive disorders in the course of the disease which have a disadvantageous effect on the course and the prognosis. On the other hand depression is also a risk factor for certain neurological diseases as was recently demonstrated in a meta-analysis of prospective cohort studies which revealed a much higher stroke risk for depressive patients. Furthermore, depression plays an important role in other neurological diseases with respect to the course and quality of life, such as Parkinson's disease, multiple sclerosis and epilepsy. This article gives a review of the most important epidemiological, pathophysiological and therapeutic aspects of depressive disorders as a comorbidity of neurological diseases and as a risk factor for neurological diseases.

Abstract
Epilepsy is one of the most common neurological disorders in the pediatric age range, and the majority of affected children can be safely and effectively treated with antiepileptic medication. While there are many antiepileptic agents on the market, specific drugs may be more efficacious for certain seizure types or electroclinical syndromes. Furthermore, certain adverse effects are more common with specific classes of medication. Additionally patient-specific factors, such as age, race, other medical conditions, or concurrent medication use may result in higher rates of side effects or altered efficacy. Significant developmental changes in gastric absorption, protein binding, hepatic metabolism, and renal clearance are seen over the pediatric age range, which impact pharmacokinetics. Such changes must be considered to determine optimal dosing and dosing intervals for children at specific ages. Furthermore, approximately one third of children require polytherapy for seizure control, and many more take concurrent medications for other conditions. In such children, drug–drug interactions must be considered to minimize adverse effects and improve efficacy. This review will address issues of antiepileptic drug efficacy, tolerability and ease of use, pharmacokinetics, and drug–drug interactions in the pediatric age range.

Cognitive-behavioral therapy for depression in patients with temporal lobe epilepsy: a pilot study. Epilepsy Behav 2012; 23:52-6.

Abstract
Depression has a high prevalence among patients with temporal lobe epilepsy (TLE). A pilot study was carried out to evaluate group cognitive-behavioral therapy (CBT) as a treatment for depression in patients with TLE. Twenty-three outpatients with TLE and major depressive disorder, according to DSM-IV criteria, were enrolled and divided into two groups to receive 16 weekly sessions of CBT. The primary outcome measures were depression severity (assessed with the Beck Depression Inventory) and quality of life (measured with the Quality of Life in Epilepsy-31). Sixteen patients (70%) completed at least 80% of the sessions. From week 8, CBT had a significant positive effect on severity of depression that lasted until the end of treatment. A significant improvement in quality of life was also observed. CBT seems to be a useful intervention for treating depression and improving quality of life in patients with TLE.

Abstract
OPINION STATEMENT In this article, we review the current best evidence for the treatment of depression in patients with epilepsy. Depression is a common epilepsy comorbidity, but it is often unrecognized. The most important step in appropriately managing mood disorders in this population is making the diagnosis. Clinical vigilance and routine use of a validated screening tool can improve detection and quality of care. As is increasingly the case for the general population, persons with epilepsy are often interested in exploring alternative therapies for chronic conditions, including depression. Unfortunately, the benefit of complementary and alternative therapies for depression currently is largely unproven for persons with a seizure history, although an early study of exercise for mild depression has shown some benefit. Concerns about drug interactions, side effects, and expense may be barriers to the prescription of antidepressant medications for people requiring chronic antiepileptic drug (AED) therapy. For this reason, use of an AED with mood-stabilizing properties has appeal and may be appropriate for selected individuals with mild depressive symptoms. Undue fear of lowering seizure threshold should not preclude the prescription of an antidepressant medication, as the perceived risks are often overestimated and rarely outweigh the risk of leaving depression untreated. At present, the best evidence for efficacy and safety support the use of citalopram, sertraline, or mirtazapine as initial pharmacotherapy, whereas bupropion should be avoided. Start low, go slow, and use the lowest effective dose. Cognitive behavioral therapy is a valuable adjunct to antidepressant therapy in this population. For people with refractory partial epilepsy and refractory depression, vagus nerve stimulation has some appeal, in that it may be beneficial for both conditions, but the efficacy of vagus nerve stimulation in improving mood in patients with epilepsy remains unclear.

Abstract
A great number of clinical observations show a relationship between epilepsy and depression. Idiopathic generalized epilepsy, including absence epilepsy, has a genetic basis. The review provides evidence that WAG/Rij rats can be regarded as a valid genetic animal model of absence epilepsy with comorbidity of depression. WAG/Rij rats, originally developed as an animal model of human absence epilepsy, share many EEG and behavioral characteristics resembling absence epilepsy in humans, including the similarity of action of various antiepileptic drugs. Behavioral studies indicate that WAG/Rij rats exhibit depression-like symptoms: decreased investigative activity in the open field test, increased immobility in the forced swimming test, and decreased sucrose consumption and preference (anhedonia). In addition, WAG/Rij rats adopt passive strategies in stressful situations, express some cognitive disturbances (reduced long-term memory), helplessness, and submissiveness, inability to make choice and overcome obstacles, which are typical for depressed patients. Elevated anxiety is not a characteristic (specific) feature of WAG/Rij rats; it is a characteristic for only a sub-strain of WAG/Rij rats susceptible to audiogenic seizures. Interestingly, WAG/Rij rats display a hyper-response to amphetamine similar to anhedonic depressed patients. WAG/Rij rats are sensitive only to chronic, but not acute, antidepressant treatments, suggesting that WAG/Rij rats fulfill a criterion of predictive validity for a putative animal model of depression. However, more and different antidepressant drugs still await evaluation. Depression-like behavioral symptoms in WAG/Rij rats are evident at baseline conditions, not exclusively after stress. Experiments with foot-shock stress do not point towards higher stress sensitivity at both behavioral and hormonal levels. However, freezing behavior (coping deficits) and blunted response of 5HT in the frontal cortex to uncontrollable sound stress, increased c-fos expression in the terminal regions of the meso-cortico-limbic brain systems and greater DA response of the mesolimbic system to forced swim stress suggest that WAG/Rij rats are vulnerable to some, but not to all types of stressors. We propose that genetic absence epileptic WAG/Rij rats have behavioral depression-like symptoms, are vulnerable to stress and might represent a model of chronic low-grade depression (dysthymia). Both 5HT and DAergic abnormalities detected in the brain of WAG/Rij rats are involved in modulation of vulnerability to stress and provocation of behavioral depression-like symptoms. The same neurotransmitter systems modulate SWDs as well. Recent studies suggest that the occurrence and repetition of absence seizures are a precipitant of depression-like behavior. Whether the neurochemical changes are primary to depression-like behavioral alterations remains to be determined. In conclusion, the WAG/Rij rats can be considered as a genetic animal model for absence epilepsy with comorbidity of dysthymia. This model can be used to investigate etiology, pathogenic mechanisms and treatment of a psychiatric comorbidity, such as depression in absence epilepsy, to reveal putative genes contributing to comorbid depressive disorder, and to screen novel psychotropic drugs with a selective and/or complex (dual) action on both pathologies.

Abstract
The literature is filled with reports that link medications with the onset or progression of depression. Because depression is so common in patients with medical illness, assessing whether a medication has in fact caused depression, or whether the relationship is coincidental, can be challenging. In this article, we review the literature on the association between medications and depression. For most agents, there are case reports or small studies linking the medication with the onset of depression, but more rigorous prospective studies are either lacking or found no association between the agent and depression. However, several medications, (eg, barbiturates, vigabatrin, topiramate, flunarizine, corticosteroids, mefloquine, efavirenz, and interferon-α) do appear to cause depression in some patients and should be used with caution in patients at risk for depression.

Abstract
Depressive symptoms are common in essential tremor (ET) and may be a primary feature of the underlying disease. However, it is still unclear whether depression in ET and depression in primary affective disorders share common clinical manifestations. Sixty-one depressed ET patients and 112 depressed patients without ET were assessed using the Montgomery-Asberg Depression Rating Scale (MADRS). We compared the individual depressive symptoms of the two groups by comparing MADRS subitem scores. Although there was no significant difference between the level of cognitive function and the severity of depression, patients with ET had a lower score on items "reported sadness", "inability to feel" and "pessimistic thoughts", and a higher score on items "concentration difficulties" and "lassitude" than those of patients without ET. These results show that depressive symptoms in patients with ET possess distinct characteristics compared to those in depressed patients without ET.

Abstract
PURPOSE Patients with epilepsy often suffer from concomitant psychiatric disorders. Treatment patterns and the extent of comorbidity are insufficiently investigated and appropriate methods are scarce. The purpose of the study was to estimate the prevalence of psychiatric comorbidity in patients with epilepsy and to investigate prescription patterns of drugs prescribed for psychiatric disorders in epilepsy. METHODS Prescription data from the Norwegian Prescription Database (NorPD) regarding the use of CNS-active drugs included anonymous data from almost 190,000 patients and 1.1-1.3 million prescriptions per year (2004-2007). Searches were based upon use of specific drugs, defined daily doses, number of patients, prescriptions, gender, and age. Reimbursement codes related to psychiatric diagnosis were used as indicators for clinical use. RESULTS The prevalence of psychiatric comorbidity in patients with epilepsy was estimated to be 32%. There were 56% women and 44% men participating in the study. Among patients using antidepressants two thirds were women, but no gender differences were seen with antipsychotic medication. Antidepressants and antipsychotics were used 3.4 (20.9%) and 5.8 (13.4%) times more frequently than in the general population, accounting for 7.88 and 1.99 defined daily doses (DDDs)/1,000 inhabitants/day/year respectively. Lamotrigine was the most commonly used antiepileptic drug (AED) in epilepsy, accounting for 33% of the use of AEDs (in total 5.65 DDDs/1,000 inhabitants/day/year). The use of benzodiazepines was 9.55 DDDs/1,000 inhabitants/day/year. The patients had complex pharmacotherapy with two to eight concomitant drugs. CONCLUSION The present study gives an estimate of psychiatric comorbidity of 32% in patients with epilepsy in a nation-wide population. The pharmacotherapy in this patient population is complex. The results provide valuable data on prescription patterns that contribute to pharmacovigilance on a national scale.

Abstract
Background and Purpose The risk of suicide or suicide attempts is reported higher in people with epilepsy (PWE) than in the general population. Although epileptic, psychiatric, and psychosocial factors are known risk factors for suicide or suicide attempt, no studies have evaluated the predictors of the severity of suicidal ideation-which is a warning sign for suicide attempts-in PWE. Therefore, we measured the severity of suicidal ideation and its risk factors. Methods Consecutive PWE who were medicated with antiepileptic drugs (AEDs) and attended epilepsy clinic were included in the study. The subjects completed self-reported questionnaires, which included the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Symptom Checklist-90-Revised (SCL-90-R), and Scale for Suicide Ideation-Beck (SSI-Beck). We compared the patients' demographic and clinical variables, and BDI, BAI, and SCL-90-R scores with their SSI-Beck score, and used our findings to determine the predictors for suicidal ideation. Results In total, 257 PWE were enrolled in the study. SSI-Beck scores correlated strongly with several seizure-related variables, duration of education, IQ, BDI and BAI scores, and nine domains of the SCL-90-R questionnaire. However, the strongest predictor for suicidal ideation was BDI score (β=0.41, p<0.001), followed by several SCL-90-R domains, such as obsessive-compulsive (β=-0.39, p<0.001), depression (β=0.38, p<0.001), hostility (β=0.22, p=0.002), paranoid ideation (β=0.17, p=0.01), and IQ (β=-0.10, p=0.017). These variables explained 59% of the variance in the SSI-Beck score. The seizure-related variables that influenced the BDI score were seizure frequency, duration of education, MRI abnormality, and number of AEDs. However, these variables explained only 18% of the variance in the BDI score. Conclusions Major risk factors for suicidal ideation in PWE were depressive and psychiatric symptoms rather than seizure-related variables. Therefore, clinicians should focus on screening for depression and other psychiatric problems and treat them appropriately in order to reduce suicidal behavior in PWE. Since seizure-related variables also exhibited a minor role in determining depressive symptoms, stronger seizure-related risk factors for depression should be sought, such as seizure severity or psychosocial factors, to minimize suicidal behavior.

Abstract
Limbic psychotic trigger reaction (LPTR) includes paroxysmal, motiveless, unplanned felonies, all committed during flat affect, autonomic arousal and a fleeting de novo psychosis. It is considered as a form of non-convulsive behavioural seizures (NCBS). A transient limbic hyperactivation is probably implicated that impairs prefrontal monitoring but preserves memory for the acts. LPTR may, however, not be limited to felonies which have attracted forensic attention. There may exist many more 'merely' social misbehaviours, undetected and untreated as a 'sleeper' case. This kind of possible undetected LPTR cases, exemplified by a patient who suffers from paroxysmal hallucinations triggering her to attempt to commit infanticide, is presented herein. Our patient had repetitive occurrence of episodes and remission of the symptomatology after the administration of oxcarbazepine, facts that support the epileptic origin of the disorder.

Abstract
Animal studies have shown endocrine changes after levetiracetam treatment. The present study investigated reproductive and sexual function in patients with epilepsy (aged 18-45) treated with levetiracetam (LEV: 30 men/26 women), carbamazepine (CBZ: 63 men/30 women), or lamotrigine (LTG: 37 men/40 women) monotherapy and in healthy controls (36 men/44 women). In women, no endocrine changes were observed during LEV treatment, whereas steroid hormone-binding globulin levels were greater and progesterone levels lower in women using CBZ. Dehydroepiandrosterone sulfate levels were higher and androstenedione levels lower in LTG-treated women. Arizona Sexual Experience Scale scores, which were significantly lower in females using LTG or LEV, suggesting they have better sexual function than CBZ users and controls. In men, no drug-specific hormonal pattern was observed after LEV treatment. Male patients in all treatment groups had lower androstenedione and free testosterone. Those using CBZ had lower free androgen indices and dehydroepiandrosterone sulfate levels, and higher steroid hormone-binding globulin, follicle-stimulating hormone, and luteinizing hormone levels. Arizona Sexual Experience Scale scores for men were similar in all groups. In conclusion, LEV treatment apparently has no drug-specific sexual or endocrine side effects in men or women in this age group.

Abstract
BACKGROUND Neuropeptide Y (NPY) has been implicated in depression, anxiety, and memory. Expression of human NPY and the number of NPY-positive neurons in the rodent amygdala correlate with anxiety and stress-related behavior. Increased NPY expression in the epileptic brain is supposed to represent an adaptive mechanism counteracting epilepsy-related hyperexcitability. We attempted to investigate whether NPY-positive neurons in the human amygdala are involved in these processes. METHODS In 34 adult epileptic patients undergoing temporal lobe surgery for seizure control, the density of NPY-positive neurons was assessed in the basal, lateral, and accessory-basal amygdala nuclei. Cell counts were related to self-reported depression, anxiety, quality of life, clinical parameters (onset and duration of epilepsy, seizure frequency), antiepileptic medication, and amygdala and hippocampal magnetic resonance imaging volumetric measures. RESULTS Densities of NPY-positive basolateral amygdala neurons showed significant positive correlations with depression and anxiety scores, and they were negatively correlated with lamotrigine dosage. In contrast, NPY cell counts showed no relation to clinical factors or amygdalar and hippocampal volumes. CONCLUSIONS The results point to a role of amygdalar NPY in negative emotion and might reflect state processes at least in patients with temporal lobe epilepsy. Correlations with common clinical parameters of epilepsy were not found. The question of a disease-related reduction of the density of NPY-positive amygdalar neurons in temporal lobe epilepsy requires further investigation.

Abstract
PURPOSE The WAG/Rij strain of rats, a well-established model for absence epilepsy, has comorbidity for depression. These rats exhibit depression-like behavioral symptoms such as increased immobility in the forced swimming test and decreased sucrose intake and preference (anhedonia). These depression-like behavioral symptoms are evident in WAG/Rij rats, both at 3-4 and 5-6 months of age, with a tendency to aggravate in parallel with an increase in seizure duration. Here we investigated whether the behavioral symptoms of depression could be prevented by the suppression of absence seizures. METHODS Ethosuximide (ETX; 300 mg/kg/day, in the drinking water) was chronically applied to WAG/Rij rats from postnatal day 21 until 5 months. Behavioral tests were done before the cessation of the treatment. Electroencephalography (EEG) recordings were made before and after cessation of treatment to measure seizure severity at serial time-points. RESULTS ETX-treated WAG/Rij rats exhibited no symptoms of depression-like behavior in contrast to untreated WAG/Rij rats of the same age. Moreover, treated WAG/Rij rats did not differ from control age-matched Wistar rats. ETX treatment led to almost complete suppression of spike-wave discharges (SWDs) in 5-6 month old WAG/Rij rats. Discontinuation of chronic treatment was accompanied by a gradual emergence of SWDs; however, a persistent reduction in seizure activity was still present 47 days after discontinuation of the chronic treatment. DISCUSSION The results suggest that seizure activity is necessary for the expression of depression-like behavioral symptoms and confirm that epileptogenesis can be prevented by early and chronic treatment.

Abstract
Physical approaches for the treatment of epilepsy currently under study or development include electrical or magnetic brain stimulators and cooling devices, each of which may be implanted or applied externally. Some devices may stimulate peripheral structures, whereas others may be implanted directly into the brain. Stimulation may be delivered chronically, intermittently, or in response to either manual activation or computer-based detection of events of interest. Physical approaches may therefore ultimately be appropriate for seizure prophylaxis by causing a modification of the underlying substrate, presumably with a reduction in the intrinsic excitability of cerebral structures, or for seizure termination, by interfering with the spontaneous discharge of pathological neuronal networks. Clinical trials of device-based therapies are difficult due to ethical issues surrounding device implantation, problems with blinding, potential carryover effects that may occur in crossover designs if substrate modification occurs, and subject heterogeneity. Unresolved issues in the development of physical treatments include optimization of stimulation parameters, identification of the optimal volume of brain to be stimulated, development of adequate power supplies to stimulate the necessary areas, and a determination that stimulation itself does not promote epileptogenesis or adverse long-term effects on normal brain function.
