Depression and anxiety before and after temporal lobe epilepsy surgery.

PURPOSE: To examine the course of depression and anxiety in patients with temporal lobe epilepsy (TLE) treated with epilepsy surgery (and anticonvulsant drugs) or medical means alone. METHODS: Of 94 TLE patients evaluated for epilepsy surgery, 76 underwent a resective procedure, 18 continued on medical treatment alone. Depression (Beck Depression Inventory (BDI)) and anxiety scores (Self-Rating Anxiety Scale (SRAS)) were examined during presurgical evaluation (T1) and after a mean of 16 months (T2), or 12 months after surgery. Depression and anxiety scores were related to type of intervention, underlying epileptogenic lesion, change of seizure control and anticonvulsant therapy. RESULTS: At T1, depression and anxiety scores were higher in patients with TLE than scores in published normal populations. At T2, depression but not anxiety scores were significantly lower than at T1. Change of depression scores interacted with improvements of seizure control. CONCLUSIONS: Evidence of depression and anxiety is commonly found in patients with TLE. Depression improves not because of epilepsy surgery per se, but because of improved seizure control. This is more commonly achieved by surgery than medical treatment. The results are consistent with the hypothesis that depression in TLE is caused by pathological epileptic activity rather than a fixed structural defect.     

Affective symptoms and determinants of health-related quality of life in Mexican people with epilepsy

Epilepsy is known to be associated with multiple psychiatric comorbidities, such as depression, sleep-disorders, and anxiety. The objective of this study was to determine the prevalence and impact of affective symptoms over health-related quality of life (QOL) in Mexican people with epilepsy (PWE). We performed a cross-sectional observational study on 73 consecutive PWE and corresponding age- and sex-matched controls. HrQOL was assessed using the QOLIE-10 (QOL in Epilepsy-10) instrument. Clinical and demographic characteristics were recorded, and instruments evaluating depressive/anxiety symptoms, sleep quality, and insomnia were completed. PWE had more depressive/anxiety symptoms when compared with controls. QOLIE-10 scores were significantly inversely correlated with poor sleep quality, insomnia symptoms, depressive/anxiety symptoms, and number of anti-epileptic drugs used, but not with seizure type or number of seizures per month. A poor QOL was independently associated only with anti-epileptic drug polytherapy. PWE are burdened with depressive/anxiety symptoms at alarming rates. The presence of depressive symptoms along with sleep disturbances and more significantly, anti-epileptic drug polytherapy, appears to negatively impact QOL, to a greater degree than short-term seizure control.     

Psychosocial adjustment of epilepsy patients in Cyprus

This study investigated aspects of psychosocial adjustment in epilepsy patients in Cyprus. Sixty-three patients under 55years of age with idiopathic or symptomatic epilepsy and 89 neurologically matched healthy volunteers participated. Subjects completed the State and Trait Anxiety Inventory and the Beck Depression Inventory; patients with epilepsy also completed the Epilepsy Foundation Concerns Index. Results showed that patients with symptomatic epilepsy had significantly higher scores on state and trait anxiety and depressive symptoms. Sociodemographic characteristics including gender, marital status, and education levels contributed to differences in trait and state anxiety, depressive symptom scales, autonomy concerns, and fear for seizure recurrence. Variables such as poor seizure control and use of polytherapy were associated with lower adjustment scores and reduced psychosocial outcome. Finally, patients with epilepsy scored significantly higher on depression and anxiety symptoms. The results provide further evidence on challenges patients with epilepsy face and on the need for implementing psychosocial prevention programs.     

What is the role of depressive symptoms among other predictors of quality of life in people with well-controlled epilepsy on monotherapy?

The quality of life (QOL) of individuals with well-controlled epilepsy (WCE) is often not considered. We therefore investigated predictors determining QOL in patients who had been seizure free at least 1 year on stable antiepileptic drug (AED) monotherapy. They were asked to complete self-report health questionnaires, including the Beck Depression Inventory (BDI), Adverse Event Profile (AEP), and Quality of Life in Epilepsy Inventory-31 (QOLIE-31). We looked for predictors of QOLIE-31 scores among the various demographic, socioeconomic, and clinical factors and BDI, and AEP scores. Depression symptoms were manifested by 18.7% of patients. People with depression symptoms were more likely to report adverse events than those without depression symptoms. The strongest predictor of QOL was BDI score, followed by AEP total score, years of education, and income. BDI score had 3.37 times the effect of AEP total score. In conclusion, QOL of patients with WCE is determined mainly by depressive symptoms.     

Quality of life in community-dwelling patients with schizophrenia in China

The aim of this study was to assess Chinese schizophrenia patients' quality of life (QOL) and identify its demographic and clinical correlates. A random sample of 540 community-dwelling schizophrenia patients was interviewed using standardized assessment instruments. The patients' basic sociodemographic and clinical data and QOL were collected. Compared with the general population, patients had significantly lower scores in the physical and psychological QOL domains. Multivariate analyses showed that better social support independently predicted higher QOL in all domains, whereas more severe positive symptoms predicted worse psychological and environmental domains. Overall psychopathology predicted both worse physical and psychological domains; depressive symptoms and being married predicted worse physical and social QOL, respectively. Our results suggest that therapeutic and psychosocial interventions alleviating positive and depressive symptoms and improving poor social support and marriage-related problems in Chinese patients with schizophrenia might be of considerable benefit in improving their QOL.     

Treatment of depression in patients with temporal lobe epilepsy: A pilot study of cognitive behavioral therapy vs. selective serotonin reuptake inhibitors

There is a high prevalence of depression in patients with epilepsy, which negatively impacts their quality of life (QOL) and seizure control. Currently, the first-line of treatment for depression in patients with epilepsy is based on selective serotonin reuptake inhibitors (SSRIs). The main objective of this pilot study was to compare cognitive behavioral therapy (CBT) versus SSRIs for the treatment of major depressive disorder (MDD) in patients with temporal lobe epilepsy (TLE). Seven patients who received group CBT were compared with eight patients treated with SSRIs. All were diagnosed with MDD and TLE. Patients were assessed at baseline before treatment and at six and 12 weeks during treatment with the Quality of Life in Epilepsy Scale of 31 items (QOLIE 31), the Beck Depression Inventory (BDI), and the Hospital Anxiety and Depression Scale (HADS). Seizure records were also taken on a monthly basis. After 12 weeks of treatment, both groups showed improved QOL and reduced severity of depression symptoms. There were no statistically significant group differences in the final scores for the BDI (p = 0.40) and QOLIE 31 (p = 0.72), although the effect size on QOL was higher for the group receiving CBT. In conclusion, the present study suggests that both CBT and SSRIs may improve MDD and QOL in patients with TLE. We found no significant outcome differences between both treatment modalities. These findings support further study using a double-blind controlled design to demonstrate the efficacy of CBT and SSRIs in the treatment of MDD and QOL in patients with TLE.     

Quality of life of Chinese schizophrenia outpatients in Hong Kong: relationship to sociodemographic factors and symptomatology

OBJECTIVE: To explore the relationships between sociodemographic and clinical factors and quality of life (QOL) in a cohort of Chinese schizophrenia outpatients. METHOD: Two hundred subjects with a diagnosis of DSM-IV schizophrenia aged 18-60 years were randomly selected, and their sociodemographic and clinical characteristics including psychotic and depressive symptoms, extrapyramidal symptoms (EPS), and quality of life were assessed. Correlation and multiple regression analyses were used to evaluate the relationships of sociodemographic, clinical data and QOL. RESULTS: Compared to normative data obtained for the general population in Hong Kong, significantly lower scores in physical, psychological, and social QOL domains were found in the patient group. History of suicidal attempts and the presence of positive, negative, depressive, anxiety and EPS symptoms were all significantly correlated with QOL in schizophrenia patients. After controlling for the effects of variables that were significantly correlated with QOL in the correlation analysis, however, only depressive symptoms were still significantly correlated with each QOL domain. Multiple regression analysis showed that depressive symptoms predicted all QOL domains, while positive symptoms predicted overall and physical QOL domains. CONCLUSIONS: Chinese outpatients with schizophrenia had poorer QOL than the general population. In this patient population, QOL was more strongly related to the severity of depressive symptoms and was independent of sociodemographic factors.     

Anxiety and depression in children with epilepsy and their mothers

OBJECTIVE: Children with epilepsy have high rates of depression and anxiety. The majority of studies concentrate on the children with epilepsy, but the emotional impact of epilepsy on family members is of clinical concern. In this cross-sectional study we aimed to examine the association between epilepsy in childhood and adolescence, and anxiety and depression in these patients and their mothers. METHODS: We studied 35 children and adolescents with seizures (age range, 7-19 years), 35 gender-matched healthy controls (age range, 8-17) who did not have any chronic medical illness, and mothers of these individuals (n=70) in a cross-sectional analysis. We administered the Kovac Child Depression Inventory (CDI) and State-Trait Anxiety Inventory for Children (STAIc) to the children. We administered the Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI) to the mothers of these children. Pearson correlations were used to analyze dependence between variables, and Student's t test was used to compare mean values between test scores. RESULTS: Patients with epilepsy had higher CDI scores (mean+/-SD, 12.48+/-6.35) than controls (9.31+/-5.11) (P<0.05), whereas the STAIc scores did not differ between cases (34.03+/-8.29) and controls (35.20+/-6.23) (P<0.05). Mothers of children with epilepsy did not have more depression or anxiety symptoms than mothers of children without epilepsy as measured by BDI and STAI scores (P>0.05). There was no correlation between mothers' scores and patients' or controls' scores. CONCLUSIONS: These results support findings from previous studies that children and adolescents with epilepsy have a higher frequency of depressive but not anxiety symptoms than the general population of healthy children and that this is independent of their mothers' symptoms.     

Preoperative depressive symptoms predict postoperative seizure outcome in temporal and frontal lobe epilepsy

ObjectiveRecent research has pointed to the possibility of a bidirectional relationship between seizure frequency in epilepsy and depressive symptoms. The study described here investigated the relationship between preoperative depressive symptomatology and postoperative seizure outcome in a sample of patients with temporal (TLE) and frontal (FLE) lobe epilepsy.MethodsA retrospective analysis was conducted on the data from 115 eligible patients with TLE (N = 97) and FLE (N = 18) and resections limited to one cortical lobe who were evaluated preoperatively and 1 year after epilepsy surgery with respect to depressive symptoms (Beck Depression Inventory, BDI) and seizure outcome. The latter was assessed in terms of actual total seizure frequency as well as a dichotomous variable (seizure free vs. not seizure free) for the 1-year outcome. Repeated-measures analyses of variance and regression analyses were applied.ResultsSeizure-free patients had significantly lower BDI scores preoperatively as well as postoperatively than patients who were not seizure free. In the regression analyses, the preoperative BDI score was a significant predictor of postoperative seizure frequency as well as seizure freedom. When only patients with TLE were analyzed, the results for the association between preoperative BDI and postoperative seizure frequency and seizure freedom remained consistent.ConclusionThe present results provide evidence for a statistical bidirectionality of the relationship between depressive symptoms and postoperative seizure status in a mixed sample of patients with TLE and FLE. Possible reasons for this bidirectional association include an underlying common pathology in both depression and epilepsy, for example, structural changes or functional alterations in neurotransmitter systems.     

Quality of life and depressive symptoms in patients with major depression and end-stage renal disease: a matched-pair study

OBJECTIVE: To compare the quality of life (QOL) and depressive symptoms of outpatients with major depression with that of nondepressed individuals undergoing hemodialysis (matched for age, gender, and ethnicity). METHODS: We used the WHOQOL BREF and the Beck Depression Inventory (BDI). RESULTS: After univariate analyses, depressed patients' QOL scores were significantly lower (P<.0001) in all the assessed domains (i.e., physical health, psychological, social relationships, environmental, and global QOL). Additionally, there was a significant difference in the severity of depression among the study groups (P<.0001). Finally, after multiple regression analysis, the QOL profile of depressed subjects remained significantly worse even when controlling for depression scores and diagnostic status. CONCLUSION: The subjective QOL of patients with major depression is significantly lower than that of subjects undergoing hemodialysis.     

Quality of life one year after epilepsy surgery

BackgroundThe aim of surgery for medically intractable epilepsy was to achieve seizure freedom and improve overall quality of life (QOL) in patients. This investigation looked at changes in QOL one year after epilepsy surgery and the relationship of changes to mood, language, and seizure outcomes.MethodDepressive symptoms, QOL, and naming were measured in 25 patients with temporal lobe epilepsy before and one year after dominant temporal lobe resection. The Quality of Life in Epilepsy-89 (QOLIE-89), Beck Depression Inventory II (BDI-II), and Boston Naming Test (BNT) were used, respectively, and seizure outcome was reported according to the Engel classifications. Minimum clinically important differences (MCID) and reliable change indices (RCI) were used to assess the proportion of patients who achieved meaningful improvement or worsening in the respective areas of functioning, and the relationship between outcomes was evaluated. Changes on the 17 individual items of the QOLIE-89 were also assessed.ResultsOverall, there was a significant improvement in QOL, reduction in depressive symptoms, and decline in naming one year after surgery. Positive clinically important improvement in QOL was achieved in 76% of patients, meaningful reduction of depressive symptoms was achieved in 20%, and clinically important naming declines were observed in 48% of the cohort. Sixteen patients were seizure-free one year after surgery, but there was no significant correlation between changes in QOL and seizure outcome, depressive symptoms, or naming.ConclusionThe results in the reported cohort of patients showed that surgical treatment of temporal lobe epilepsy in the dominant hemisphere resulted in clinically meaningful improvement in overall QOL and declines in naming but no significant reduction of mood disturbance.     

A psychosocial view of anxiety and depression in epilepsy

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.     

Changes in quality of life and self-perspective related to surgery in patients with temporal lobe epilepsy

PURPOSE: To evaluate changes in intractable epilepsy patients in terms of quality of life, depression, anxiety, stigma, and impact of epilepsy before and after surgery. METHODS: Twenty patients with intractable temporal lobe epilepsy who were waiting for surgery (pre-SAH group) and 21 patients who had already undergone surgery (post-SAH group) were studied. All patients received SF-36, Beck Depression Inventory, State-Trait Anxiety Inventory, stigma and impact of epilepsy inventories, and a form asking their own perspectives about epilepsy and surgery. RESULTS: Post-SAH group scored higher on all subscales of SF-36, with only RE scores being significantly better (t=-1.98, P=.05). Although depression, anxiety, and stigma scores were higher in pre-SAH group, only impact of epilepsy scores were significantly higher in pre-SAH group (t=-2.951, P=.005). Seizure frequency and comorbidity had significant effects on QOL where amount of AEDs and QOL were negatively related (r=-0.318, P<0.05). Both groups stated lack of independence and social activities as the main concern (48.8%) and recovery from epilepsy as the most important expectation from surgery (85.4%). Post-surgical group mentioned the difference in their life after surgery as independence and increase in social activities (47.6%). CONCLUSION: QOL of patients after surgery was found to be better than before surgery. Results also revealed that seizure frequency, comorbidity, and anti-epileptic medication affected health related QOL negatively. Impact of epilepsy levels was found to be higher among the pre-SAH patients. Finally, independence seemed to be the most important concern and gain for Turkish epilepsy patients.     

Normalization of quality of life three years after temporal lobectomy: a controlled study

PURPOSE: The goal of epilepsy surgery is not merely to control previously intractable seizures, but also to improve quality of life (QOL). Our goals were to assess, in our Middle Eastern population, the QOL of adults with temporal lobe epilepsy (TLE) 3 years after temporal lobectomy as compared with matched TLE patients who did not undergo surgery and with healthy individuals in the same community. METHODS: Twenty consecutive TLE patients who underwent temporal lobectomy 3 years previously were matched in the following variables: age, sex, seizure frequency, seizure duration, age at onset of epilepsy, duration of epilepsy, and number of medications, with 17 TLE patients who underwent the presurgical evaluation and subsequent optimization of medical therapy but did not undergo surgery. They were also matched for age, sex, educational level, income, and residence with 20 healthy individuals. All groups were interviewed by using the ESI-55 questionnaire. RESULTS: Compared with the nonsurgery group, QOL was significantly better in the surgery group (85% seizure free) in the well-being, functioning, and role-limitation domains. QOL was similar in the surgery and healthy control groups in all domains and scales. The nonsurgery group scored significantly lower than healthy controls in the functioning and role-limitation domains. CONCLUSIONS: Intractable TLE was associated with marked impairments in QOL despite continued attempts to optimize medical therapy. Three years after temporal lobectomy QOL in our patient population achieved levels similar to those of matched healthy individuals. To our knowledge, this is the first study to report normalization of QOL after temporal lobectomy, in any population.     

Suicide outcomes after resective epilepsy surgery

People with epilepsy have a higher risk for suicide than people without epilepsy. The relationship between seizure control and suicide is controversial. A standardized protocol to record history, diagnostic testing, and neuropsychiatric assessments was administered. The Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI) were administered presurgically and yearly for up to 5 years. Among the 396 enrolled, 4 of 27 deaths were attributed to suicide. The standardized mortality ratio, compared with suicides in the U.S. population and adjusted for age and gender, was 13.3 (95% CI=3.6-34.0). Only one patient had a BDI score suggestive of severe depression (BDI=33), one had depressive symptoms that did not the meet the depressive range (BDI=7), and the other two reported no depressive symptoms. Two of the patients reported moderate to severe anxiety symptoms (BAI=17 and 21, respectively). Suicide may occur after epilepsy surgery, even when patients report excellent seizure control.     

Quality of life and associated factors among adults with epilepsy in Nigeria

OBJECTIVE: Epilepsy is a common condition worldwide and has been observed to affect quality of life (QOL). Though, much has been written on this subject among western populations, little research has been done in developing countries of Africa including Nigeria. The study aims to identify factors associated with quality of life among adult epilepsy patients in this environment. METHOD: Respondents were evaluated using the 10-item Quality of Life in Epilepsy Inventory (QOLIE-10), the 30-item General Health Questionnaire (GHQ-30), the modified Mini Mental State Examination (mMMSE),and the Hospital Anxiety and Depression Scale (HADS). Diagnosis of epilepsy was based on clinical and electroencephalographic findings. RESULTS: The mean age of the 51 respondents was 27.7 years (SD = 9.7). Thirteen (25.5%) had an average of 2 seizure episodes in the month preceding the interview, while 37 (72.5%) have had the condition for more than 5 years. Factors that were significantly associated with overall quality of life included being female (p < 0.05), seizure frequency (p < 0.01), using more than 1 anti-epileptic drugs (AEDs) (p < 0.01), GHQ-30 score (p < 0.01), high anxiety score (p < 0.001), and high depression score (p < 0.01). Multiple regression analysis showed that depressive symptoms were the single most important factor explaining low QOL. Other factors were GHQ-30 score, seizure frequency, and being a woman. CONCLUSION: Controlling seizures and paying attention to the psychological needs of adult epileptics will have a positive effect on the QOL among Nigerian epileptics.     

Factors associated with impaired quality of life in younger and older adults with epilepsy

The purpose of this study is to weigh psychological state, patients' demographics, seizure-related factors, and medical comorbidity in older adults with epilepsy against the same parameters in younger adults in an attempt to identify best quality of life (QoL) predictors. The Quality of Life in Epilepsy Inventory for Adults (QOLIE-31) and the Beck Depression Inventory-II (BDI-II) were completed by 146 patients with localization-related epilepsy. There was no statistical difference in the QOLIE-31 total score between younger and older adults. Best QoL predictors were BDI-II and seizure frequency, with BDI-II providing more than 3 times the impact of seizure frequency. BDI-II also substantively predicted most QOLIE-31 domains. Additionally, epilepsy duration positively correlated with overall QoL only among older adults. In summary, in younger as well as older adult epilepsy patients, depressive symptoms emerge as the strongest predictor of QoL. However, older adults appear to adapt better to their chronic health problem.     

Determinants of quality of life in people with epilepsy in Serbia

PurposeThis study aimed at finding determinants of quality of life in people with epilepsy (PWE) living in Belgrade, Serbia.MethodIn this study, we recruited consecutive adults with epilepsy attending our outpatient department. Adult patients (age range: 18–65 years) of normal intelligence and without any progressive neurological disease or psychiatric disorder were included in the study. They completed the following questionnaires: QOLIE-31 Inventory (Serbian version), Beck's Depression Inventory-II, Beck's Anxiety Inventory, Symptom Check List-90, and Neurotoxicity Scale-II. Hierarchical multiple regression analysis was performed to assess the predictive effects of some factors on QOLIE-31 Inventory.ResultsThe mean QOLIE-31 score of 203 patients who completed the questionnaires was 70.64 ± 17.74. Sociodemographic factors (age, sex, education, and employment) did not significantly predict QOLIE-31 score. Significant determinants of quality of life were clinical characteristics – seizure severity and etiology of epilepsy – accounting for 30.9% of the variance, depressive and anxiety symptoms accounting for 42.8% of the variance, and cognitive effects of antiepileptic drugs, accounting for 1.5% above other variables.ConclusionsThe results suggest that seizure severity and etiology of epilepsy, depressive and anxiety symptoms, and cognitive adverse medication effects are main determinants of quality of life in this population of PWE.     

Significant improvement in the quality of life of Brazilian depressed outpatients 12 weeks following the start of antidepressants

Studies on the impact of depression should go beyond estimating its prevalence and the severity of symptoms to include investigations that seek to establish how it influences the quality of life (QOL) of the affected individuals. Although some depression trials have included QOL measures, assessments were mostly retrospective and relatively infrequent. In the present investigation, 73 patients presenting a severe episode of major depression were assessed by the WHOQOL BREF and the Beck Depression Inventory (BDI) at the start of antidepressant treatment and again after a mean of 12 weeks. After analyses, depressed patients' QOL scores significantly improved in all the assessed domains (i.e., physical health, psychological, social relations, environmental, and overall QOL) over the study period. Additionally, there was a significant improvement in depressive symptoms between test and retest. Effect sizes for these differences ranged from 0.49 to 1.08 (i.e., medium to large effects). After multiple regression analyses, age, psychiatric comorbidity, and depressions scores were independent predictors of some of the QOL domains (i.e., physical, psychological, and overall). In conclusion, antidepressant treatment seems to be associated with significant improvements in multiple QOL domains in patients with severe major depression. However, our findings are preliminary and suggest that additional controlled and long-term studies are needed.     

A prospective audit of adjunctive zonisamide in an everyday clinical setting

ObjectiveThe purpose of the study was to delineate how affective symptoms (AS) influence quality of life (QOL) for individuals with drug-refractory epilepsy (DRE) and those with well-controlled epilepsy (WCE) independently.MethodsAll subjects participating in the study were asked to complete reliable and validated self-report health questionnaires, including AS, measured with the Korean versions of the Beck Depression Inventory, Beck Anxiety Inventory, and Quality of Life in Epilepsy Inventory-31 (QOLIE-31). We examined predictors of QOLIE-31 scores among the various demographic and clinical factors. We compared the effects of AS on QOL between patients with DRE and those with WCE and investigated the differential effects of seizure control and AS on QOL.ResultsTwo hundred forty-nine patients with DRE or WCE were included in the study. The strongest predictor of QOL was AS, followed by seizure control and MRI abnormality. Affective symptoms had almost two times the effect of seizure control and six times the effect of MRI abnormality. Poorest QOL was noted in patients with DRE with AS, followed by those with WCE with AS, DRE without AS, and WCE without AS.ConclusionThe major determinant of QOL in patients with epilepsy is AS rather than DRE or WCE status.
