Drug-resistant epilepsy in Morocco: description, prevalence and predictive factors in Casablanca-Settat region. J Clin Neurosci 2024; 126:28-37. [PMID: 38824801 DOI: 10.1016/j.jocn.2024.05.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Revised: 05/08/2024] [Accepted: 05/28/2024] [Indexed: 06/04/2024]
Abstract
Drug-resistant epilepsy (DRE) affects about one-third of people with epilepsy (PWE). Our study aims to estimate the DRE prevalence and its predictive factors in Morocco. A cross-sectional study was conducted over 18 months. PWE with clinical diagnosis of epilepsy, and with an antiseizure treatment duration >12 months were examined in the neurology, neurosurgery, psychiatry, and pediatrics departments, of different sampled clinical sectors for the Casablanca-Settat region. Sociodemographic and clinical data were collected using a questionnaire during consultations. Antiseizure multi-therapy, a seizure freedom duration <12 months, compliance, and adequate posology were the determining factors for classifying DRE. Data were analyzed using Statistical Package for Social Sciences (SPSS) software, version 21.0. Statistical significance was set at p < 0.05 and logistic regression was performed to determine the predictive factors. In our sample of 446 PWE, the median age is 25 years (IQR: 11.75-44.00). The DRE estimated prevalence was 29.4 %. Pseudo-resistant epilepsy (PRE) was 18.0 %. Multivariate logistic regression analysis reports that single marital status (ORa = 1.94; CI95%: 1.02-3.71), comorbidities and concomitant affections (ORa = 2.14; CI95%: 1.27-3.59), structural etiology (ORa = 1.96; CI95%: 1.16-3.30), pre-ictal aura (ORa = 1.90; CI95%: 1.09-3.29), inter-ictal EEG abnormalities (ORa = 2.45; CI95%: 1.24-4.84) and allopathic treatment use (ORa = 2.10; CI95%: 1.30-3.39) are the predictive factors for DRE. We report an alarming DRE prevalence. Associated factors found may contribute to the prognosis and early management. PWE awareness, facilitating healthcare access and the development of epilepsy surgery are the key points to limit DRE in Morocco and prevent its various complications, especially for the pediatric population.

Abstract
ABSTRACT The aim of this study was to analyze the behavior and histopathological changes in the hippocampus of epileptic Wistar rats treated with acupuncture associated or not with phenobarbital. The experiment used 44 male rats with 90 days of birth, induced to status epileptics with pilocarpine hydrochloride in a single dose of 350mg/kg, separated into treatment groups and submitted for 5 minutes to the elevated plus-maze test. Group 1 received 0.2mL of saline solution orally; Group 2 treated with acupuncture at the yintang, baihui, shishencong, jizhong, naohu, thianzu points; Group 3 received orally phenobarbital, daily dose of 20mg/kg; Group 4 treated with an association of acupuncture and oral phenobarbital; Group 5 random needling. The results obtained showed that Groups 2 (acupuncture) and 4 (acupuncture and phenobarbital) presented decreased anxiety, epileptic seizures, and neuronal death in the CA1, CA3 areas of the hippocampus when compared to animals in groups 1, 3 and 5. It is concluded that the association of phenobarbital and acupuncture points used in the experiment allowed for the control of epileptic seizures, reduction of anxiety and reduction of lesions in the subareas of the hippocampus.

Abstract
OBJECTIVES To prospectively compare the frequencies of depression and anxiety in patients with new onset functional seizures versus two age and gender-matched control groups consisting of patients with new onset epileptic seizures and normal individuals. METHODS Consecutive patients, 16 years and older, enrolled in a prospective study for suspected new onset epileptic seizures and diagnosed with documented functional seizures were included. We compared the depression and state and trait anxiety scores using the Beck Depression Inventory (BDI) and the State Trait Anxiety Inventory (STAI) between patients with functional seizures and the other two control groups. RESULTS The 33 patients with functional seizures had significantly higher depression and anxiety scores compared to those with epileptic seizures and normal controls. Twenty patients (60.6%) in the functional seizures group scored in the "depression" range compared to 5/33 (15.2%) in the epileptic seizures and 1/33 (3%) in the control groups. In the functional seizures group, 14/33 (42.4%) had scores in the "state anxiety" range compared to 6/33 (18.2%) and 2/33 (6.1%) in the epileptic seizures and normal control groups, respectively. Similarly, 15/33 (51.5%) of patients in the functional seizures group had scores in the "trait anxiety" range compared to 4/33 (12.1%) and 1/33 (3%) in the epileptic seizures and normal control groups, respectively. CONCLUSIONS Our results indicate that patients with new onset functional seizures frequently suffer from depression and anxiety at the time of their initial evaluation. These findings underscore the importance of screening for depression and anxiety in that patient population.

Improved irritability, mood, and quality of life following introduction of perampanel as late adjunctive treatment for epilepsy. Epilepsy Behav 2020; 104:106883. [PMID: 32045874 DOI: 10.1016/j.yebeh.2019.106883] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2019] [Revised: 12/17/2019] [Accepted: 12/18/2019] [Indexed: 02/07/2023]
Abstract
OBJECTIVE The objective of this study was to evaluate the efficacy and tolerability of perampanel (PER) in late adjunctive treatment of focal epilepsy. We assessed outcomes 1) according to patients' clinical profiles and the broad mechanism of action (MoA) of concomitant antiepileptic drugs (AEDs) and 2) the effects of PER on adverse events, irritability, mood, and quality of life (QOL). METHODS Consecutive patients commenced on PER at two epilepsy centers in Melbourne, Australia were identified. A nested cohort underwent detailed prospective assessment, while the remainder were retrospectively analyzed. Six- and 12-month efficacy endpoints were at least a 50% reduction in seizure frequency (responders) and complete seizure freedom. The prospective cohort underwent standardized validated questionnaires at 0, 1, 3, 6, and 12 months using the modified semi-structured seizure interview (SSI), Liverpool Adverse Events Profile (LAEP), Quality of Life in Epilepsy-Patient-Weighted (QOLIE-10-P), Neurological Disorders Depression Inventory Epilepsy (NDDI-E), and an Irritability Questionnaire. RESULTS One hundred sixty patients were followed for a median of 6 months: the mean number of prior AEDs was 6, 99% had drug-resistant epilepsy, and 72% had never experienced a prior seizure-free period of at least 6 months (=continuously refractory epilepsy). Perampanel was associated with responder and seizure freedom rates of 30.6% and 9.4% at 6 months and 19.4% and 4.4% (5.6% adjusted for the titration period) at 12 months. Having "continuously refractory epilepsy" was associated with a reduced likelihood of seizure freedom at 6 months (5% vs. 30%; p = 0.001) and 12 months (3% vs. 13%; p = 0.058). Quality of Life in Epilepsy-Patient-Weighted, irritability, and NDDI-E showed mean improvement at 6 months from baseline. SIGNIFICANCE Even when used as late add-on adjunctive therapy in patients with highly refractory focal epilepsy, PER can result in 12-month seizure freedom of 5.6%. The likelihood of seizure freedom was associated with prior "continuous medication refractoriness". Six months after introduction of PER patients reported improved mood, QOL, and decreased irritability.

Abstract
The aim of this study was to test the validity and reliability of the Turkish version of the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), which was developed to rapidly investigate depressive symptoms in patients with epilepsy. A consecutive sample of 51 patients with epilepsy was included in the study. The Beck Depression Inventory (BDI) and the Turkish version of the NDDI-E were applied to the participants. During the application, it was observed that the participants could quickly fill the scale without any difficulties in understanding the translated items. The Cronbach's α coefficient was 0.721. Receiver operating characteristic analysis showed an area under the curve of 0.902 (95% confidence interval [CI] = 0.822-0.983), a cutoff score of >15, a sensitivity of 88.2%, a specificity of 82.4%, a positive predictive value of 71.4%, a negative predictive value of 93.3%. The NDDI-E Turkish version scores were significantly and positively correlated with those of the BDI (Spearman's ρ = 0.832, p < 0.001). In conclusion, it has been determined that the Turkish version of the NDDI-E can be used as a valid and reliable measurement tool to detect major depression in Turkish people with epilepsy.

Abstract
Depression episodes in epilepsy is the most common commorbidity, affecting between 11% and 62% of patients with epilepsy. Although researchers have documented a strong association between epilepsy and psychiatric comorbidities, the nature of this relationship is poorly understood. The manifestation of depression in epilepsy is a complex issue having many interacting neurobiological and psychosocial determinants, including clinical features of epilepsy (seizure frequency, type, foci, or lateralization of foci) and neurochemical or iatrogenic mechanisms. Other risk factors are a family history of psychiatric illness, particularly depression, a lack of control over the seizures and iatrogenic causes (pharmacologic and surgical). In addition, treatment with antiepileptic drugs (AEDs) as well as social coping and adaptation skills have also been recognised as risk factors of depression associated with epilepsy. Epilepsy may foster the development of depression through being exposed to chronic stress. The uncertainty and unpredictability of seizures may instigate sadness, loneliness, despair, low self-esteem, and self-reproach in patients with epilepsy and lead to social isolation, stigmatization, or disability. Often, depression is viewed as a reaction to epilepsy's stigma and the associated poor quality of life. Moreover, patients with epilepsy display a 4-5 higher rate of depression and suicide compared with healthy population.

Abstract
Epilepsy is a common neurological disease, affecting 2.4million people in the US. Among the many different forms of the disease, temporal lobe epilepsy (TLE) is one of the most frequent in adults. Recent studies indicate the presence of a hyperactive hypothalamopituitary- adrenocortical (HPA) axis and elevated levels of glucocorticoids in TLE patients. Moreover, in these patients, stress is a commonly reported trigger of seizures, and stress-related psychopathologies, including depression and anxiety, are highly prevalent. Elevated glucocorticoids have been implicated in the development of stress-related psychopathologies. Similarly, excess glucocorticoids have been found to increase neuronal excitability, epileptiform activity and seizure susceptibility. Thus, patients with TLE may generate abnormal stress responses that both facilitate ictal discharges and increase vulnerability for the development of comorbid psychopathologies. Here, we will examine the evidence that the HPA axis is disrupted in TLE, consider potential mechanisms by which this might occur, and discuss the implications of HPA dysfunction for seizuretriggering and psychiatric comorbidities.

Abstract
BACKGROUND A high prevalence of mood disorders exists in patients with epilepsy. In most cases, this is not detected and, consequently, not treated. This study aimed to determine the prevalence and correlates of major depressive disorder (MDD) among adolescents with epilepsy attending a child and adolescent clinic in Nigeria. METHODS We recruited 156 participants consecutively for the study. Adherence was assessed using the 8-item Morisky Medication Adherence Questionnaire, while the K-SADS was used to assess the presence of major depressive disorder. Seizure control was evaluated by the frequency of seizures within a year. RESULTS Major depressive disorder (DSM-IV criteria) was diagnosed in 28.2% of the participants. The age of participants (p=0.013), seizure control (p=0.03), medication adherence (p=0.045), frequency of seizures in the preceding 4weeks (p<0.001), and duration of illness (p<0.001) were all significantly associated with the presence of MDD. Participants with seizures occurring more than once weekly in the preceding 4weeks were 16 times more likely to have a MDD compared with those with no seizures in the preceding 4weeks (p<0.001, 95% C.I. [4.13, 65.43]), while participants with a duration of illness more than 10years were more than four times likely to have MDD compared with those with an illness duration of 5-10years (p<0.01, 95% C.I. [0.07, 0.70]). CONCLUSION The prevalence of MDD among patients with epilepsy was high. Poor seizure control, poor medication adherence, and long duration of illness were associated with the presence of MDD among such patients. Intervention should focus on ensuring good seizure control and optimal adherence in order to mitigate the impact of MDD in patients with epilepsy.

Abstract
OBJECTIVE Depression is common but frequently underdiagnosed in people with epilepsy. Screening tools help to identify depression in an outpatient setting. We have published validation of the NDDI-E and Emotional Thermometers (ET) as screening tools for depression (Rampling et al., 2012). In the current study, we describe a model of an optimized screening tool with higher accuracy. METHODS Data from 250 consecutive patients in a busy UK outpatient epilepsy clinic were prospectively collected. Logistic regression models and recursive partitioning techniques (classification trees, random forests) were applied to identify an optimal subset from 13 items (NDDI-E and ET) and provide a framework for the prediction of class membership probabilities for the DSM-IV-based depression classification. RESULTS Both logistic regression models and classification trees (random forests) suggested the same choice of items for classification (NDDI-E item 4, NDDI-E item 5, ET-Distress, ET-Anxiety, ET-Depression). The most useful regression model includes all 5 mentioned variables and outperforms the NDDI-E as well as the ET with respect to AUC (NDDI-E: 0.903; ET7: 0.889; logistic regression: 0.943). A model developed using random forests, grown by restricting the possible splitting of variables to these 5 items using only subsets of the original data for single classification, performed similarly (AUC: 0.949). CONCLUSIONS For the first time, we have created a model of a screening tool for depression containing both verbal and visual analog scales, with characteristics supporting that this will be more precise than previous tools. Collection of a new data sample to assess out-of-sample performance is necessary for confirmation of the predictive performance.

Abstract
AIM: To investigate factors related to hopelessness in a sample of epileptic patients, including measures of depression and quality of life (QOL).
METHODS: Sixty-nine participants were administered the following psychometric instruments: Beck Depression Inventory-II, Beck Hopelessness Scale (BHS), and QOL in Epilepsy (QOLIE)-89. Patients were dichotomized into two categories: those affected by epilepsy with generalized tonic-clonic seizures vs those having epilepsy with partial seizures.
RESULTS: The groups differed on the QOLIE Role Limitation/Emotional dimension. Patients with generalized seizures reported more limitations in common social/role activities related to emotional problems than patients with other types of epilepsy (89.57 ± 25.49 vs 72.86 ± 36.38; t63 = -2.16; P < 0.05). All of the respondents reported moderate to severe depression, and 21.7% of patients with generalized seizures and 28.6% of patients with other diagnoses had BHS total scores ≥ 9 indicating a higher suicidal risk. The study did not control for years of the illness.
CONCLUSION: Patients with generalized seizures reported more limitations in common social/role activities related to emotional problems compared to patients with other types of seizures. Patients at increased suicide risk as evaluated by the BHS were older than those who had a lower suicidal risk. Future studies are required to further investigate the impact of hopelessness on the outcome of epileptic patients.

Abstract
Psychiatric co-morbidities in epilepsy are of great concern. The current study investigated the relative contribution of structural and functional connectivity (FC) between medial temporal (MT) and prefrontal regions in predicting levels of depressive symptoms in patients with temporal lobe epilepsy (TLE). Twenty-one patients with TLE [11 left TLE (LTLE); 10 right TLE (RTLE)] and 20 controls participated. Diffusion tensor imaging was performed to obtain fractional anisotropy (FA) of the uncinate fasciculus (UF), and mean diffusivity (MD) of the amygdala (AM) and hippocampus (HC). Functional MRI was performed to obtain FC strengths between the AM and HC and prefrontal regions of interest including anterior prefrontal (APF), orbitofrontal, and inferior frontal regions. Participants self-reported depression symptoms on the Beck Depression Inventory-II. Greater depressive symptoms were associated with stronger FC of ipsilateral HC-APF, lower FA of the bilateral UF, and higher MD of the ipsilateral HC in LTLE, and with lower FA of the contralateral UF in RTLE. Regression analyses indicated that FC of the ipsilateral HC-APF was the strongest contributor to depression in LTLE, explaining 68.7% of the variance in depression scores. Both functional and microstructural measures of frontolimbic dysfunction were associated with depressive symptoms. These connectivity variables may be moderating which patients present with depression symptoms. In particular, FC MRI may provide a more sensitive measure of depression-related dysfunction, at least in patients with LTLE. Employing sensitive measures of frontolimbic network dysfunction in TLE may help provide new insight into mood disorders in epilepsy that could eventually guide treatment planning.

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
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
RATIONALE Depression and anxiety are more strongly associated with quality of life (QOL) than seizure frequency in several populations with epilepsy. However, QOL is culturally determined and may be influenced by cultural values and norms as well as local policies and resources. The goal of this study is to investigate the impact of neuropsychiatric symptoms and seizure severity on QOL and employment in people with epilepsy living in Jordan. METHODS Seizure severity and complications, antiepileptic drug side effects, social stigma, neuropsychiatric symptoms, and mental health (MH-SF36) and physical health (PH-SF36) domains of QOL were assessed in 45 adult patients with epilepsy in a university neurology clinic. Multivariate regression analysis was used to evaluate the relationship between these variables and the quality of life of Jordanians with epilepsy. RESULTS Neuropsychiatric symptoms, seizure frequency, and history of injury due to seizure were associated with the MH-SF36. However, earlier age of seizure onset, longer duration of epilepsy, unemployment, and history of chronic disease was associated with lower PH-SF36 scores. Furthermore, there were no differences in QOL, neuropsychiatric symptoms, and seizure frequency in Jordanians who were employed versus unemployed in this study. CONCLUSIONS Neuropsychiatric symptoms were significantly associated with mental health-related QOL measures, but not with physically-related QOL measures, in Jordanians with epilepsy. For studies across populations, it is critical to separate mental health from physical health QOL measures. Furthermore, regional differences in culture and policy may more strongly influence employment status than individuals' experiences of epilepsy, neuropsychiatric symptoms, or QOL in some populations.

Abstract
UNLABELLED The aim of the study was to assess the determinants of quality of life (QOL) in adult patients with refractory focal epilepsy who were not eligible for surgery or who rejected surgery after presurgical evaluation. The QOLIE-31, the Hospital Anxiety and Depression Scale and PESOS questionnaire were mailed in 2009 to all adult patients who had been evaluated for suitability for epilepsy surgery between 2001 and 2007 in the Bethel Epilepsy Center and had been deemed not eligible for surgery or had decided against surgery. Questionnaires were sent by post to 359 patients: 172 (47.9%) replied, and of these, 125 patients were eligible for this study. The remaining 47 patients were excluded mainly because they did not fulfill the criteria of refractory epilepsy. Out of the included 125 patients, 106 were considered to be poor surgical candidates for medical reasons, and 19 had decided against surgery. The mean follow-up was 4.1±2.1 years. In the past 6 months, 13.9% of the patients were seizure free, 12 of them (9.6%) were seizure free for one year, 10.7% had 1-2 seizures, 11.5% had 3-5 seizures, 27.0% had one or more seizures a month, 23.0% had one or more seizures a week, and 13.9% had one or more seizures a day. Patient-perceived changes in their seizures since presurgical evaluation were rated by 15.6% of the patients as 'improved significantly', by 28.7% as 'improved', by 46.7% as 'no change', by 6.6% as 'deteriorated' and by 2.5% as 'significantly deteriorated'. Quality of life in patients with refractory epilepsy was much lower compared to operated patients from our center. Multivariate analysis of QOL showed that depression and anxiety are strong predictors but not exclusively. Furthermore, tolerability and efficacy of AEDs are significant predictors of most QOLIE-31 subscales. Employment, seizure frequency, patient-perceived change in their seizures, number of AEDs and the degree of comorbidity appeared as predictors for some aspects of QOL as well. When excluding anxiety and depression, the most important predictors of QOL were tolerability of AEDs and employment. For other aspects of QOL, efficacy of AEDs, gender, number of AEDs, degree of comorbidity and a certificate of disability were additional predictors. The results of the multivariate analysis did not essentially change when seizure-free patients were excluded. CONCLUSION Quality of life in non-operated patients with refractory epilepsy is significantly lower than in operated patients from the same center. Besides depression and anxiety, patient-rated tolerability and efficacy of AEDs, seizure frequency and employment are the main determinants of QOL.

Abstract
Epilepsy and depression share an unusually high coincidence suggestive of a common etiology. Disrupted production of adult-born hippocampal granule cells in both disorders may contribute to this high coincidence. Chronic stress and depression are associated with decreased granule cell neurogenesis. Epilepsy is associated with increased production - but aberrant integration - of new cells early in the disease and decreased production late in the disease. In both cases, the literature suggests these changes in neurogenesis play important roles in their respective diseases. Aberrant integration of adult-generated cells during the development of epilepsy may impair the ability of the dentate gyrus to prevent excess excitatory activity from reaching hippocampal pyramidal cells, thereby promoting seizures. Effective treatment of a subset of depressive symptoms, on the other hand, may require increased granule cell neurogenesis, indicating that adult-generated granule cells can modulate mood and affect. Given the robust changes in adult neurogenesis evident in both disorders, competing effects on brain structure are likely. Changes in relative risk, disease course or response to treatment seem probable, but complex and changing patterns of neurogenesis in both conditions will require sophisticated experimental designs to test these ideas. Despite the challenges, this area of research is critical for understanding and improving treatment for patients suffering from these disorders.

Abstract
The aims of this study were to record behavioral problems in children with epilepsy (CWE), compare the prevalence with that reported among healthy children without epilepsy, and investigate the risk factors. A child behavioral questionnaire for parents comprising 15 items was administered to the main caregiver of 108 CWE and 108 controls matched for age in Kilifi, Kenya. CWE had a higher mean score for reported behavioral problems than controls (6.9 vs 4.9, t=4.7, P<0.001). CWE with active epilepsy also recorded more behavioral problems than those with inactive epilepsy (8.2 vs 6.2, t=-2.9, P=0.005). A significantly greater proportion of CWE (49% vs 26% of controls) were reported to have behavioral problems. Active epilepsy, cognitive impairment, and focal seizures were the most significant independent covariates of behavioral problems. Behavioral problems in African CWE are common and need to be taken into consideration in planning comprehensive clinical services in this region.

Abstract
OBJECTIVE The aim of the work described here was to characterize quality of life (QOL) and its determinants in a large cohort of adult patients with epilepsy. METHODS Validated measures reflecting disease severity and psychosocial functioning were electronically collected on all outpatients seen during 2009. Multivariate regression adjusting for repeated measures identified determinants of QOL, as defined by the Quality of Life in Epilepsy Questionnaire-10 (QOLIE-10). RESULTS Seven thousand seven hundred eighty-four visits from patients with epilepsy were identified. The questionnaire completion rate was 77%, yielding 5960 records corresponding to 1931 individual patients for analysis. Following multivariate modeling, the two most clinically significant QOL predictors were seizure severity (mean QOLIE-10 score=28.8 if LSSS>40 vs 19.2 otherwise) and depression (mean QOLIE-10 score=31.7 if PHQ-9≥10 vs 19.3 otherwise). CONCLUSIONS Optimizing quality of life in patients with epilepsy requires an approach that extends beyond controlling seizures. Collection of validated health status measures improving patient management is possible within the setting of routine clinical care.

Abstract
Stress is a commonly reported seizure precipitant among individuals with epilepsy. Yet, the relationship between stress and seizure susceptibility remains unclear. This study examined the relationship between emotional distress and lifetime seizure load in individuals with temporal lobe epilepsy (TLE), as well as the potential moderating effect of explanatory style on this relationship. Data were collected from 148 individuals with TLE. Scales 2 and 7 of the Minnesota Multiphasic Personality Inventory were used as a measure of emotional distress, and explanatory style was measured using the Revised Optimism-Pessimism Scale. Elevated Scale 2 scores were associated with an increase in seizure load only in subjects with Full Scale IQ scores> or =92. An interaction between emotional distress and explanatory style was not observed. Thus, for individuals with higher levels of intelligence, depression may be an important pathway in linking emotional distress to poor seizure control.

Abstract
OBJECTIVE: understand the psychological considerations of the relationship between the effect of seizures upon the patients' perception of seizure control, depression, anxiety and quality of life (QoL). METHODS: 151 adult patients with epilepsy diagnosed for over two years were interviewed and responded the 31-Item Quality of Life in Epilepsy (QOLIE-31), the Trait Form of the State/Trait Anxiety Inventory (STAI II) and the Beck Depression Inventory (BDI). RESULTS: 45 patients were depressed (29.8%) and 29 (19.2%) had anxiety. Depression scores ranged from 0 to 49 (M=7.4; SD=8.9) and anxiety scores ranged from 19 to 69 (M=41.5, SD=11.9). Total QoL score was correlated to seizure control (p<0.001), perception of epilepsy control (p<0.001), anxiety (p<0.001), and depression (p=0.003). The perception of epilepsy control was correlated to seizure control (p<0.001), seizure frequency (p=0.001), anxiety (p<0.001) and depression (p<0.001). Seizure control was associated to anxiety (p=0.033) and depression (p<0.001). There was co-morbidity between anxiety and depression (p<0.001). CONCLUSION: This study highlights the importance of the seizure frequency and control to the evaluation of perception of epilepsy control and shows that anxiety and depression in epilepsy are predicted by seizure-related (seizure frequency and control) and psychosocial aspects (perception of control and QoL) together.

Abstract
The current study sought to characterize and compare personality traits of patients with temporal lobe epilepsy (TLE) and frontal lobe epilepsy (FLE). Ninety-seven adults with medically intractable epilepsy (TLE n=58, FLE n=39) completed the Personality Assessment Inventory (PAI) as part of routine preoperative investigations. Not surprisingly, both epilepsy groups endorsed significantly more symptoms across PAI clinical scales than the normative sample, most notably on scales assessing Depression and Somatic Complaints. Direct comparison of personality profiles of people with FLE and TLE revealed that FLE was associated with relative elevations on scales assessing emotional lability and relationship difficulties (i.e., Mania, Borderline Features, Antisocial, Stress, and Nonsupport). Although effect sizes were moderate to large, the clinical significance of these differences was questionable (<1 SD). However, results of a logistic regression suggested that the Borderline Features and Anxiety scales have incremental validity in predicting seizure site (FLE vs TLE) above education and duration of recurrent seizures. These results suggest that patients with FLE may exhibit more behavioral traits associated with frontal dysfunction than patients with TLE.

Abstract
The mammalian brain contains a population of neurons that are continuously generated from late embryogenesis through adulthood-after the generation of almost all other neuronal types. This brain region-the hippocampal dentate gyrus-is in a sense, therefore, persistently immature. Postnatal and adult neurogenesis is likely an essential feature of the dentate, which is critical for learning and memory. Protracted neurogenesis after birth would allow the new cells to develop in conjunction with external events-but it may come with a price: while neurogenesis in utero occurs in a protected environment, children and adults are exposed to any number of hazards, such as toxins and infectious agents. Mature neurons might be resistant to such exposures, but new neurons may be vulnerable. Consistent with this prediction, in adult rodents seizures disrupt the integration of newly generated granule cells, whereas mature granule cells are comparatively unaffected. Significantly, abnormally interconnected cells may contribute to epileptogenesis and/or associated cognitive and memory deficits. Finally, studies increasingly indicate that new granule cells are extremely sensitive to a host of endogenous and exogenous factors, raising the possibility that disrupted granule cell integration may be a common feature of many neurological diseases.

Abstract
In this cross-sectional study our aim was to evaluate the effect of depression on academic achievement in children with epilepsy and low school performance. Fifty-one children with epilepsy and low school performance were evaluated with the Children's Depression Inventory (CDI) to measure depressive symptoms. School performance was evaluated with Achenbach's Child Behavior Checklist (CBCL) and the Teacher Report Form (TRF). Children diagnosed with depressive spectrum disorders received medical therapy. All tests were administered in the first interview and repeated at the end of 6 months of therapy. Forty-three children completed the study. The patients were evaluated with DSM-IV diagnostic criteria. Accordingly, 9 (20.9%) children had Major Depressive Disorder (MDD) and 4 (9.3%) had Depressive Disorder, Not Otherwise Specified (DD-NOS). All children with MDD and DD-NOS received antidepressant medication, but only seven of them completed treatment. Posttreatment CDI scores were significantly lower, and TRF scores also improved. Pediatric neurologists should be aware of the possibility of depressive disorders in children with epilepsy, especially in those with low school performance.

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

Abstract
Depression is a frequent comorbidity in epilepsy patients. A variety of biological factors may underlie epilepsy-associated depression. We examined whether kindling-induced chronic increase in seizure susceptibility is accompanied by behavioral symptoms of depression. Three-week-old Wistar rats underwent rapid kindling: 84 initially subconvulsant electrical stimulations of ventral hippocampus delivered every 5 minutes, followed by depression-specific behavioral tests performed 2 and 4 weeks later. Kindled animals exhibited a sustained increase in immobility time in the forced swim test and the loss of taste preference toward calorie-free saccharin, as compared with controls. Initial loss of preference toward the intake of calorie-containing sucrose was followed by the increased consumption at 4 weeks. At both time points, animals exhibited enhanced seizure susceptibility on test stimulations of the hippocampus. We conclude that neuronal plastic changes associated with the kindling state are accompanied by the development of depressive behavior.

Abstract
The main purpose of the present article is to review the possible risk factors for suicidal behaviour in epilepsy with a special emphasis on the different antiepileptic drugs (AEDs). Epidemiological data show that, in general, the suicide rate among patients with epilepsy is 5-fold higher than that in the general population, while in temporal lobe epilepsy and complex partial seizures it is approximately 25-fold higher. A certain psychiatric comorbidity may provoke suicidality in patients with epilepsy, and depression and cognitive impairment seem to be the main risk factors for suicidality in epilepsy. In addition, depression and cognitive deterioration in epilepsy may share common neuropsychological mechanisms in terms of hypofrontality. This may cause similar psychopathological signs in both diagnostic categories, including suicidality. Analysis of the literature has shown that serotonin metabolism disturbances are involved in the pathogenesis of suicidal behaviour irrespective of primary diagnosis. Serotonin disturbances also seem to be a common link between depression, suicidality and even epilepsy itself. The various AEDs differ not only in their mechanisms of action, but also in influences on cognition and mood in epileptic patients and suicidality, respectively. Until now, only Ketter's hypothesis has been proposed to explain the psychotropic effects of different AEDs, although it does not explain the positive psychotropic effects of some AEDs, such as carbamazepine and oxcarbazepine. According to this model, all psychotropic effects of AEDs may be the result of effects on the function of two types of receptor functions: gamma-aminobutyric acid (GABA) ergic and antiglutamatergic; other possible mechanisms have not been incorporated. Presumably, other neurochemical mechanisms, and a serotonergic mechanism in particular, should also be taken into account when explaining the psychotropic effects of different AEDs. Based on these data, it has been suggested that AEDs with certain serotonergic properties should reduce the suicidality risk because they exert effects similar to antidepressants (i.e. selective serotonin reuptake inhibitors), whereas AEDs that lack serotonergic mechanisms would not be effective in suicidality prevention. In line with this paradigm, phenobarbital and phenytoin seem to be the only drugs with proven suicidality risk. On the other hand, carbamazepine, oxcarbazepine, valproate and lamotrigine could be regarded as drugs with antisuicidal properties because they all improve cognitive functions and mood in epileptic patients, and possess serotonergic mechanisms of action. The other AEDs, including topiramate, tiagabine, vigabatrin, levetiracetam and zonisamide, all exert negative effects on mood and cognition, although their influence on suicidality has not been proven in evidence-based studies yet. Although zonizamide has serotonergic properties, it exerts negative psychotropic effects, whereas gabapentin is devoid of serotonergic properties but has positive psychotropic effects on mood and cognition. To more fully explain the positive and negative psychotropic effects and influence on suicidality of AEDs, Ketter's paradigm should be supplemented by an understanding of the serotonergic mechanisms of different AEDs. Further trials are required to prove or refute this model.

Abstract
The aim of this study was to study anxiety and depression in patients with epilepsy and evaluate their relationships with neuroepilepsy and psychological variables. neuroepilepsy and psychological variables. Sixty patients and 60 healthy subjects were interviewed at the outpatient clinic for epilepsy, using the Beck Depression Inventory and State-Trait-Anxiety Inventory. The objective of the semistructured interview was to identify the patients' perception of the disease, self-concept, personal strategies, and perception of seizure control. There was a significant difference in anxiety and depression between the groups, as well as a strong relationship between perception of seizure control and depression and anxiety, independently assessed. Epilepsy was associated with disease (63.4%), mental problems (11.6%), feelings of shame, fear, worry, and low self-esteem (56.6%), and perception of stigma (26.6%). The strategies were: looking for social support, seeking medical treatment, withdrawal, denial, and spiritual support. There was a significant association between psychological symptoms and perception of seizure control, which reinforces the importance of subjective aspects involved in epilepsy.

Abstract
Major depressive disorder (MDD) is the most prevalent psychiatric comorbidity among patients with treatment-resistant seizures. The Beck Depression Inventory-II (BDI-II) is often used to measure the severity of self-reported depressive symptoms among patients with seizure disorders. In contrast, researchers often use the Profile of Mood States (POMS) Depression (D) scale to assess depressed mood among other medical patient groups. The clinical significance of POMS-D scores among seizure disorder patients is not clear. In this study, we computed the correlation of POMS-D and BDI-II scores, determined a formula for converting POMS-D scores to BDI-II scores, and computed the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the POMS-D among seizure disorder patients. Two BDI-II cutoffs (BDI-II16 and 20) were used as criteria for significant reported depressive symptoms. We found a strong correlation between POMS-D and BDI-II scores. Analyses indicated that POMS-D scores strongly predict BDI-II scores. In addition, the sensitivity, specificity, PPV, and NPV values obtained demonstrated that POMS-D scores accurately classify seizure disorder patients who endorse significant depressive symptoms. These results suggest that the POMS-D may be effective in measuring reported depressive symptoms among seizure disorder patients.

Abstract
Comorbidity with depression is an important determinant of the quality of life for patients with epilepsy. Antidepressant medications can effectively treat depression in epileptic patients, but drug-drug interactions and epileptogenic effects of these drugs pose therapeutic challenges. The mood-stabilizing effects of antiepileptic medications may not be sufficient to treat depression. Therefore, treatments that alleviate the burden of depression without increasing seizure risk or, better yet, with the possibility of improving seizure control are worth exploring. Neuroimaging techniques, such as functional magnetic resonance imaging, are providing novel insights into the pathophysiology of depression in epilepsy. For example, there appears to be prominent brain prefrontal hypoactivity, which may be sustained by the hyperactivity of the seizure focus. If so, neuromodulatory approaches that suppress epileptic focus hyperactivity and concurrently enhance prefrontal activity may be ideally suited. Indeed, vagus nerve stimulation has been shown to yield simultaneous antiseizure and mood effects. Another neuromodulatory technique, transcranial magnetic stimulation (TMS), can also modulate brain activity, but in a noninvasive, painless, and focal manner. Depending on the stimulation parameters, it is possible to enhance or reduce activity in the targeted brain region. Furthermore, TMS has been shown to be effective in treating depression, and preliminary data suggest that this treatment may also be effective for epilepsy treatment. This article reviews these data and explores further the question of whether depression and epilepsy can be simultaneously treated with TMS for optimal therapeutic impact.

Abstract
PURPOSE To examine the association of seizures with health-related quality of life (HRQOL), physical and psychiatric comorbidities, and health behaviors. METHODS We analyzed data obtained from adults aged 18 years or older (n = 30,445) who participated in the 2002 National Health Interview Survey, an ongoing, computer-assisted personal interview of the noninstitutionalized U.S. population. RESULTS An estimated 1.4% of adults 18 years or older reported being told by a health care professional that they had seizures. Persons with seizures were significantly more likely than those without seizures to report lower levels of education, higher levels of unemployment, pain, hypersomnia and insomnia, and psychological distress (e.g., feelings of sadness, nervousness, hopelessness, and worthlessness). In addition, they were significantly more likely to report insufficient leisure-time physical activity as well as physical comorbidities such as cancer, arthritis, heart disease, stroke, asthma, severe headaches, lower back pain, and neck pain. CONCLUSIONS Our findings suggest that it is advisable for health care professionals to assess psychiatric and physical comorbidities among patients with a history of seizures potentially to improve patient health outcomes. Furthermore, public health surveillance systems should include questions on seizures, epilepsy, and mental health to better examine associations among these disorders and to better identify populations meriting further assessment and intervention.

Abstract
PURPOSE This study examined affective disorders, anxiety disorders, and suicidality in children with epilepsy and their association with seizure-related, cognitive, linguistic, family history, social competence, and demographic variables. METHODS A structured psychiatric interview, mood self-report scales, as well as cognitive and language testing were administered to 100 children with complex partial seizures (CPSs), 71 children with childhood absence epilepsy (CAE), and 93 normal children, aged 5 to 16 years. Parents provided behavioral information on each child through a structured psychiatric interview and behavior checklist. RESULTS Significantly more patients had affective and anxiety disorder diagnoses (33%) as well as suicidal ideation (20%) than did the normal group, but none had made a suicide attempt. Anxiety disorder was the most frequent diagnosis among the patients with a diagnosis of affective or anxiety disorders, and combined affective/anxiety and disruptive disorder diagnoses, in those with suicidal ideation. Only 33% received some form of mental health service. Age, verbal IQ, school problems, and seizure type were related to the presence of a diagnosis of affective or anxiety disorder, and duration of illness, to suicidal ideation. CONCLUSIONS These findings together with the high rate of unmet mental health underscore the importance of early detection and treatment of anxiety disorders and suicidal ideation children with CPSs and CAE.

Abstract
Behavioral risk factors associated with comorbidity in people with epilepsy are largely unknown. We studied a population-based sample of 8057 adults through the 2002 Behavioral Risk Factor Surveillance System, in Georgia and Tennessee, ascertaining a lifetime epilepsy prevalence of 2.1% in this population. This structured interview revealed that those with epilepsy had significantly worse self-reported fair or poor health status (39% vs 17% in adults without epilepsy), significantly greater cigarette smoking (38.8% vs 24.9% in other adults), and high rates of obesity (34.1% vs 23.7% in adults without epilepsy). Large percentages of adults with epilepsy reported currently symptomatic asthma and recent joint pain. Adults with epilepsy had lower educational attainment and lower household incomes, but a higher rate of medical insurance coverage, than did other adults. This type of population-based survey can serve to identify health disparities, behavioral risk factors for other chronic diseases, and unmet health care needs in individuals with epilepsy, and to track changes in these measures over time.

Abstract
Disease and mood states are important determinants of quality of life (QOL). Low QOL, due to mood states, can be expected especially in psychiatric disorders such as depression. However, patients with seizure disorders may be even more affected because of the combined burden of physical episodes, psychiatric comorbidities, and psychosocial factors (e.g., stigma). In this study, we compare the quality of life in seizure disorders and clinical depression. Based on our earlier findings, we hypothesize that epilepsy patients fare better than patients with psychogenic, nonepileptic seizures (PNES), and we speculate that QOL in PNES is also lower relative to clinical depression. We estimate the relationships between type of seizures (epilepsy vs PNES), depression, and QOL (SF-36) using multiple regression, and we compare the SF-36 scores of patients with epilepsy and PNES (n=194) with the normative data for clinical depression using one-sample t tests. Our findings indicate that depression contributes to the poor QOL in both epilepsy and PNES, but the patients with PNES, even those without depression, have worse QOL compared with both the epilepsy patients and the depression norms. We conclude that evaluating and treating mood states is as important as treating PNES itself when caring for patients with PNES, and it might be the first step toward improving their QOL.
