Abstract
Epilepsy and psychogenic nonepileptic seizures (PNES) are associated with reduced health-related quality of life (HRQoL). The present study investigated the profile, relationship, and predictive power of illness perceptions, psychological distress (depression and anxiety), seizure activity, and demographic factors on HRQoL in these patient groups. Patients with epilepsy (n=62) and PNES (n=45) were recruited from a United Kingdom hospital and from membership-led organizations for individuals living with seizures. Patients completed a series of self-report questionnaires assessing: anxiety (GAD-7), depression (NDDI-E), illness perceptions (B-IPQ), HRQoL (NEWQOL-6D), and seizure frequency and severity (LSSS-3). Correlational and hierarchical multiple regression analyses were conducted. Patients with epilepsy reported higher HRQoL and scored lower on measures of depression and anxiety. Patients with PNES perceived their condition as more threatening overall. In both conditions, HRQoL was negatively correlated with more severe illness perceptions and psychological distress. In epilepsy and PNES, psychological distress (epilepsy: 27%; PNES: 24.8%) and illness perceptions (epilepsy: 23.1%; PNES: 23.3%) accounted for the largest amount of variance in HRQoL. Clinical factors were found not to be significant predictors, while demographic factors predicted HRQoL in epilepsy (12.6%), but not in PNES. Our findings support the notion that psychological factors are a stronger predictor of HRQoL in epilepsy and PNES than condition-related and demographic variables. Prior research suggests that anxiety and depression are key predictors of HRQoL; this study demonstrates that the relationship between illness perceptions and HRQoL is similarly close. These findings highlight the importance of addressing patients' beliefs about their condition.

Abstract
Stress is a common and important seizure precipitant reported by epilepsy patients. Studies to date have used different methodologies to identify relationships between epilepsy and stress. Several studies have identified anxiety, depression, and childhood trauma as being more common in patients with epilepsy who report stress as a seizure precipitant compared to patients with epilepsy who did not identify stress as a seizure precipitant. In one survey study it was found that a majority of patients with stress-triggered seizures had used some type of stress reduction method on their own and, of those who tried this, an even larger majority felt that these methods improved their seizures. Additionally, small to moderate sized prospective trials, including randomized clinical trials, using general stress reduction methods have shown promise in improving outcomes in patients with epilepsy, but results on seizure frequency have been inconsistent. Based on these studies, we recommend that when clinicians encounter patients who report stress as a seizure precipitant, these patients should be screened for a treatable mood disorder. Furthermore, although seizure reduction with stress reduction methods has not been proven in a randomized controlled trial, other important endpoints like quality of life were improved. Therefore, recommending stress reduction methods to patients with epilepsy appears to be a reasonable low risk adjunctive to standard treatments. The current review highlights the need for future research to help further clarify biological mechanisms of the stress-seizure relationship and emphasizes the need for larger randomized controlled trials to help develop evidence based treatment recommendations for our epilepsy patients.

Perceived stress and its predictors in people with epilepsy. Epilepsy Behav 2016; 62:47-52.

Abstract
OBJECTIVE Perceived stress in people with epilepsy (PWE) is one of the major precipitants for seizures. We investigated the degree of perceived stress in PWE and its predictors. We also aimed to reveal the interrelationships among the predictors. METHODS This was a case-control study. Consecutive patients visiting a tertiary care epilepsy clinic completed self-reported questionnaires including the Perceived Stress Scale (PSS), Revised Stigma Scale (RSS), Korean version of the Neurological Disorders Depression Inventory for Epilepsy (K-NDDI-E), Generalized Anxiety Disorder - 7 (GAD-7), and short forms of the Patient-Reported Outcomes Measurement Information System - Sleep Disturbance (PROMIS-SD) and Patient-Reported Outcomes Measurement Information System - Sleep-Related Impairment (PROMIS-SRI) scales. RESULTS The mean score of the PSS was significantly lower in patients with well-controlled epilepsy (WCE) and higher in those with uncontrolled epilepsy compared with controls. Although several factors including demographic, socioeconomic, psychosomatic, and epilepsy-related factors were associated with the PSS score, the strongest predictor for the PSS score was the K-NDDI-E score, followed by the PROMIS-SRI score, the GAD-7 score, and seizure control. Psychosomatic factors exerted both a direct effect on the PSS score and an indirect effect on the PSS score through seizure control. CONCLUSION Rapid detection and appropriate management of psychiatric and sleep-related problems in PWE may lessen stress and aid in preventing further seizures.

Abstract
Summary
Introduction. People with epilepsy (PWE) have a higher risk of developing depression and anxiety than people without epilepsy. However, understanding and management of that issue remain under-recognized.
Aim. To emphesize: a) the relationship between depression, anxiety, and epilepsy, and b) to suggest practical strategies for their identification by clinicians.
Methods. The current literatures was reviewed investigating the impact of depression and anxiety in PWE and those examining the validity of simple screening tools for the detection of depression and anxiety.
Review. Approximately one quarter of PWE have been known to be suffered from depression. The frequency of depression and anxiety was closely related to poor seizure control. Depression and anxiety have been reported to have a bidirectional relationship with epilepsy. The higher degree of depression and anxiety was more likely to elicit the suicidal ideation and attempt, adverse events and poor compliance of antiepileptic drugs, poor surgical outcome, and eventually, poor quality of life. Furthermore, depression and anxiety were closely associated with perceived stigma, obsessive-compulsive symptom, aggression, fatigue, and perceived stress.
Conclusions. Clinicians who take care of PWE in a busy clinical setting should identify their psychiatric problems by brief screening tools and treat them instantly to minimize their negative impacts.

Rapid detection of generalized anxiety disorder and major depression in epilepsy: Validation of the GAD-7 as a complementary tool to the NDDI-E in a French sample. Epilepsy Behav 2016; 57:211-216. [PMID: 26994447 DOI: 10.1016/j.yebeh.2016.02.015] [Citation(s) in RCA: 128] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Revised: 02/09/2016] [Accepted: 02/10/2016] [Indexed: 10/22/2022]
Abstract
OBJECTIVE Generalized anxiety disorder (GAD) in people with epilepsy (PWE) is underdiagnosed and undertreated. The GAD-7 is a screening questionnaire to detect GAD. However, the usefulness of the GAD-7 as a screening tool in PWE remains to be validated. Thus, we aimed to: (1) validate the GAD-7 in French PWE and (2) assess its complementarity with regard to the previously validated screening tool for depression, the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E). METHODS This study was performed under the auspices of the ILAE Commission on Neuropsychiatry. People with epilepsy >18 years of age were recruited from the specialist epilepsy unit in Marseille, France. The Mini-International Neuropsychiatric Interview (MINI) was performed as gold standard, and the Penn State Worry Questionnaire (PSWQ) and the NDDI-E were performed for external validity. Data were compared between PWE with/without GAD using Chi(2) test and Student's t-test. Internal structural validity, external validity, and receiver operator characteristics were analyzed. A principal component factor analysis with Varimax rotation was performed on the 13 items of the GAD-7 (7 items) plus the NDDI-E (6 items). RESULTS Testing was performed on 145 PWE: mean age = 39.38 years old (SD=14.01, range: 18-75); 63.4% (92) women; 75.9% with focal epilepsy. Using the MINI, 49 (33.8%) patients had current GAD. Cronbach's alpha coefficient was 0.898, indicating satisfactory internal consistency. Correlation between GAD-7 and the PSQW scores was high (r (145)=.549, P<.0001), indicating good external validity. Factor analysis shows that the anxiety investigated with the GAD-7 and depression investigated with the NDDI-E reflect distinct factors. Receiver operator characteristic analysis showed area under the curve of 0.899 (95% CI 0.838-0.943, P < 0.0001) indicating good capacity of the GAD-7 to detect GAD (defined by MINI). Cutoff for maximal sensitivity and specificity was 7. Mean GAD-7 score in PWE with GAD was 13.22 (SD = 3.99), and that without GAD was 5.17 (SD = 4.66). SIGNIFICANCE This study validates the French language version of the GAD-7 screening tool for generalized anxiety in PWE, with a cutoff score of 7/21 for GAD, and also confirms that the GAD-7 is a short and easily administered test. Factor analysis shows that the GAD-7 (screening for generalized anxiety disorder) and the NDDI-E (screening for major depression) provide complementary information. The routine use of both GAD-7 and NDDI-E should be considered in clinical evaluation of patients with epilepsy.

Abstract
OBJECTIVE To systematically review the accuracy of the GAD-7 and GAD-2 questionnaires for identifying anxiety disorders. METHODS A systematic review of the literature was conducted to identify studies that validated the GAD-7 or GAD-2 against a recognized gold standard diagnosis. Pooled estimates of diagnostic test accuracy were produced using random-effects bivariate metaanalysis. Heterogeneity was explored using the I(2) statistic. RESULTS A total of 12 samples were identified involving 5223 participants; 11 samples provided data on the accuracy of the GAD-7 for identifying generalized anxiety disorder (GAD). Pooled sensitivity and specificity values appeared acceptable at a cutoff point of 8 [sensitivity: 0.83 (95% CI 0.71-0.91), specificity: 0.84 (95% CI 0.70-0.92)] although cutoff scores 7-10 also had similar pooled estimates of sensitivity/specificity. Six samples provided data on the accuracy of the GAD-2 for identifying GAD. Pooled sensitivity and specificity values appeared acceptable at a cutoff of 3 [sensitivity: 0.76 (95% CI 0.55-0.89), specificity: 0.81 (95% CI 0.60-0.92)]. Four studies looked at the accuracy of the questionnaires for identifying any anxiety disorder. CONCLUSIONS The GAD-7 had acceptable properties for identifying GAD at cutoff scores 7-10. The GAD-2 had acceptable properties for identifying GAD at a cutoff score of 3. Further validation studies are needed.

Abstract
PURPOSE Fatigue impairs the quality of life (QOL) of epilepsy patients, but few studies have investigated this issue and no systematic analysis of the predictors of fatigue in epilepsy patients has been performed. Thus, we investigated the degree and predictors of fatigue in epilepsy patients. METHODS We enrolled 270 consecutive adult patients with epilepsy and categorized them into three subgroups: uncontrolled epilepsy (UCE), well-controlled epilepsy (WCE), and poorly controlled epilepsy (PCE). All subjects were asked to complete the Korean versions of the Fatigue Severity Scale (K-FSS), the Neurological Disorders Depression Inventory for Epilepsy (K-NDDI-E), the Generalized Anxiety Disorder-7 (K-GAD-7) scale, and the short forms of the Patient-Reported Outcomes Measurement Information System Sleep-Related Impairment (PROMIS-SRI) and Sleep Disturbance (PROMIS-SD) scales. Additionally, 200 normal control subjects who completed the K-FSS, K-NDDI-E, and K-GAD-7 measures were included. The K-FSS scores of the epilepsy subgroups and the control group were compared, and stepwise multiple regression analysis was performed to identify predictors of high scores on the K-FSS among epilepsy patients. RESULTS The K-FSS, K-NDDI-E, and K-GAD-7 scores were higher in the epilepsy patients than in the controls. The K-FSS scores of the UCE subgroup, but not of the PCE and WCE subgroups, were higher than those of the control group. K-FSS scores of epilepsy patients were predicted by PROMIS-SRI and K-NDDI-E scores. CONCLUSIONS Fatigue was more severe in epilepsy patients than in healthy controls without epilepsy, especially when seizures were not controlled. Sleep-related impairments and depression aggravated fatigue in epilepsy patients.

Abstract
OBJECTIVE To validate the Chinese version of the Generalized Anxiety Disorder-7 (GAD-7) in Chinese people with epilepsy (PWE). METHODS A consecutive cohort of PWE from the West China Hospital was recruited. Each patient received a psychiatric evaluation comprising the Mini International Neuropsychiatric Interview (MINI) and the GAD-7. Demographic and clinical characteristics were collected. Cronbach's α coefficient was calculated and receiver operating curve (ROC) analysis was conducted. RESULTS A total of 213 PWE completed the psychiatric evaluation. The GAD-7 was easily understood and quickly completed by all participants. Fifty patients (23.5%) had GAD according to the MINI criteria. Cronbach's α coefficient for the GAD-7 was 0.888. ROC analysis showed an area under the curve of 0.974 (95% CI=0.956-0.993). At a cut-off score of >6, the GAD-7 achieved the largest Youden index of 0.854 with a sensitivity of 94%, a specificity of 91.4%, a positive predictive value of 77% and a negative predictive value of 98%. SIGNIFICANCE The Chinese version of the GAD-7 is a valuable tool for screening for GAD in Chinese PWE.

Abstract
Background Psychiatric problems have been commonly reported in patients with migraine. This study investigated the reliability and validity of the Generalized Anxiety Disorder-7 (GAD-7) and Generalized Anxiety Disorder-2 (GAD-2) in patients with migraine. Methods Subjects were recruited from a headache clinic and a neuropsychologist examined their GAD using the Mini International Neuropsychiatric Interview-Plus Version 5.0.0 (MINI). Subjects completed several instruments, including the GAD-7, the Beck Anxiety Inventory (BAI), the Migraine Disability Assessment Scale (MIDAS), the Headache Impact Test-6 (HIT-6), and the Migraine-Specific Quality of Life (MSQoL). Results Among 146 participants, 32 patients (21.9 %) had GAD as determined by the MINI. Cronbach’s α for the GAD-7 and GAD-2 were 0.915 and 0.820, respectively. At a cutoff score of 5, the GAD-7 had a sensitivity of 78.1 %, a specificity of 74.6 %, a positive predictive value (PPV) of 46.3 %, and a negative predictive value (NPV) of 92.4 %. At a cutoff score of 1, the GAD-2 had a sensitivity of 84.4 %, a specificity of 72.8 %, a PPV of 46.6 %, and a NPV of 94.3 %. The scores of the GAD-7 and GAD-2 well correlated with the BAI score, the MIDAS score, the HIT-6 score, and the MSQoL score. Conclusions The GAD-7 and GAD-2 are both reliable and valid screening instruments for GAD in patients with migraine.

Abstract
Depression and anxiety are highly prevalent in patients with epilepsy (PWE), with prevalence rates ranging from 20% to 55%. Unfortunately, the rates, patterns, and risk factors have not been well studied in the Middle East and, to our knowledge, have not been studied at all in the UAE. We screened 186 patients attending an epilepsy clinic using standardized screening tools to determine the rates of both depression and anxiety and compared these rates with that of age- and sex-matched controls. Almost one-third of our patients scored in the depression and anxiety ranges, which was significantly higher compared with the age- and sex-matched controls. Using a multiregression model, none of the studied variables were associated with an increased risk of having either disorder. Depression or anxiety symptoms independently and significantly increased the risk of association with the other disorder. Almost two-thirds of patients with depression and anxiety were not prescribed antidepressant or antianxiety medications.

Depression and Anxiety among Patients with Epilepsy and Multiple Sclerosis: UAE Comparative Study. Behav Neurol 2015; 2015:196373. [PMID: 26576071 PMCID: PMC4631862 DOI: 10.1155/2015/196373] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2015] [Revised: 10/02/2015] [Accepted: 10/13/2015] [Indexed: 11/18/2022] Open
Abstract
Depression and anxiety are highly prevalent in patients with epilepsy (PWE), with prevalence rates ranging from 20% to 55%. The cause of this increased rate is multifactorial. Depression and epilepsy are thought to share the same pathogenic mechanism. Anxiety, on the other hand, seems to have a prevalence rate among PWE comparable to, or even higher than, those reported for depression, and it is closely linked to epilepsy. To test this hypothesis, we screened for depression and anxiety 186 and 160 patients attending the epilepsy and MS clinics, respectively, using standardized screening tools to determine the rates of both depression and anxiety, comparing these rates to 186 age, sex matched controls. Among the three groups, only patients with epilepsy were at increased risk of having depression (OR = 1.9), whereas anxiety was not. This finding could point to the shared pathogenic mechanisms hypothesis between depression and epilepsy.

Prevalence of Depression and Anxiety among Patients with Multiple Sclerosis Attending the MS Clinic at Sheikh Khalifa Medical City, UAE: Cross-Sectional Study. Mult Scler Int 2015; 2015:487159. [PMID: 26240760 PMCID: PMC4512603 DOI: 10.1155/2015/487159] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2015] [Revised: 06/19/2015] [Accepted: 06/28/2015] [Indexed: 11/21/2022] Open
Abstract
Depression and anxiety are reported to be prevalent in patients with MS, with prevalence rates ranging from 20% to 50%. Unfortunately, the rates, patterns, and risk factors are not well studied in our Middle East region, and, to our knowledge, not at all in UAE. Using standardized screening tools, we observed that 17% and 20% of 80 patients seen in MS clinic had scores consistent with major depression and anxiety disorders, respectively, at a rate that was not statistically different when compared to age and sex matched controls. None of the studied variables including duration of the disease, EDSS scores, age, gender, and the level of education had any significant correlation with the rates of both disorders. Almost two-thirds of the patients with scores consistent with major depression and anxiety were not on antidepressant and antianxiety medications.

Abstract
OBJECTIVE Anxiety disorders and symptoms are highly prevalent and problematic comorbidities in people with epilepsy (PWE), yet they remain poorly understood and often go undetected. This research aimed to further our understanding about anxiety in PWE. METHODS Study 1 assessed the effectiveness of the commonly utilised yet unvalidated measure (Hospital Anxiety Depression Scale-Anxiety subscale; HADS-A) to identify DSM-IV anxiety disorders in 147 adult epilepsy outpatients. RESULTS This study found that although the HADS-A had reasonable specificity (75%), its poor sensitivity (61%) and inadequate area under the curve (.68) deemed it unreliable as a screener for anxiety disorders in this population. METHODS Study 2 aimed to further our understanding of the relationship between anxiety disorders, as defined by clinical interview, and psychosocial correlates in PWE. One hundred and twenty-two participants from Study 1 completed a battery of psychosocial measures. RESULTS Multivariate analysis revealed that the presence of an anxiety disorder was associated with unemployment, which was found to be the only independent predictor. That is, despite the fact that psychosocial factors together contributed to the variance in anxiety disorders none were revealed to be significant independent predictors. CONCLUSION These findings add to the literature indicating that the HADS may indicate distress, but does not adequately identify people with anxiety disorders and highlights the urgent need for the development of a reliable anxiety screening measure for PWE. Further, the results suggest that anxiety disorders in PWE are likely to be multiply determined with respect to psychosocial factors and require further investigation.

Seo JG, Lee JJ, Cho YW, Lee SJ, Kim JE, Moon HJ, Park SP. Suicidality and Its Risk Factors in Korean People with Epilepsy: A MEPSY Study. J Clin Neurol 2015; 11:32-41. [PMID: 25628735 PMCID: PMC4302177 DOI: 10.3988/jcn.2015.11.1.32] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2014] [Revised: 10/20/2014] [Accepted: 10/22/2014] [Indexed: 11/22/2022] Open
Abstract
Background and Purpose People with epilepsy (PWE) are more likely to experience suicidality, with suicidal ideation and attempts, than people without epilepsy (PWoE). The aims of the present study were to determine 1) the characteristics of suicidality in Korean PWE, 2) whether PWE with suicidality receive psychiatric intervention, and 3) the risk factors for suicidality. Methods Patients who consecutively visited epilepsy clinics at secondary- and tertiary-care hospitals were recruited (n=684), along with age- and sex-matched PWoE (n=229). The presence of current major depressive disorder (MDD), generalized anxiety disorder (GAD), and/or suicidality was established using the Mini International Neuropsychiatric Interview-Plus Version 5.0.0. The Korean version of the Liverpool Adverse Events Profile (K-LAEP) was applied to detect adverse effects of antiepileptic drugs (AEDs). Results Suicidality was present in 208 (30.4%) of the 684 PWE. The rate of suicidality was 4.6 times higher among PWE than PWoE, and 108 (15.7%) PWE had suicidal ideation and had attempted suicide. Among those who had attempted suicide, 40.7% had made at least two attempts. The most common method of suicide attempt was drug overdose (34.9%). Unfortunately, of the 208 PWE with suicidality, 136 (65.4%) did not receive psychiatric intervention. The risk factors for suicidality were MDD [odds ratio (OR)=6.448, 95% confidence interval (CI)=3.739-11.120, p<0.001], GAD (OR=3.561, 95% CI=1.966-6.452, p<0.001), item scores of 3 or 4 on the K-LAEP (OR=2.688, 95% CI=1.647-4.387, p<0.001), and a history of febrile convulsion (OR= 2.188, 95% CI=1.318-3.632, p=0.002). Conclusions Suicidality is more prevalent in PWE than in PWoE. Clinicians should monitor psychiatric disorders and the adverse effects of AEDs in PWE in an attempt to reduce the incidence of suicidal ideation or suicide attempts in this patient population.

Abstract
Many recent epidemiological studies have found the prevalence of depression and anxiety to be higher in people with epilepsy (PWE) than in people without epilepsy. Furthermore, people with depression or anxiety have been more likely to suffer from epilepsy than those without depression or anxiety. Almost one-third of PWE suffer from depression and anxiety, which is similar to the prevalence of drug-refractory epilepsy. Various brain areas, including the frontal, temporal, and limbic regions, are associated with the biological pathogenesis of depression in PWE. It has been suggested that structural abnormalities, monoamine pathways, cerebral glucose metabolism, the hypothalamic-pituitary-adrenal axis, and interleukin-1b are associated with the pathogenesis of depression in PWE. The amygdala and the hippocampus are important anatomical structures related to anxiety, and γ-aminobutyric acid and serotonin are associated with its pathogenesis. Depression and anxiety may lead to suicidal ideation or attempts and feelings of stigmatization. These experiences are also likely to increase the adverse effects associated with antiepileptic drugs and have been related to poor responses to pharmacological and surgical treatments. Ultimately, the quality of life is likely to be worse in PWE with depression and anxiety than in PWE without these disorders, which makes the early detection and appropriate management of depression and anxiety in PWE indispensable. Simple screening instruments may be helpful for in this regard, particularly in busy epilepsy clinics. Although both medical and psychobehavioral therapies may ameliorate these conditions, randomized controlled trials are needed to confirm that.
