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.     

Association of subjective anxiety, depression, and sleep disturbance with quality-of-life ratings in adults with epilepsy

Purpose :  To determine the relative contributions of subjective anxiety, depression, sleep disturbance, and seizure-related variables to quality-of-life scores in adults with epilepsy, and the interrelationships among these factors.
Methods :  Consecutive adult patients with epilepsy attending neurology outpatient clinics were recruited. Patients completed the following scales: Hospital Anxiety and Depression Scale (HADS), Hamilton Anxiety Rating Scale, Medical Outcomes Study (MOS) Sleep Scale, Epworth Sleepiness Scale, and Quality of Life in Epilepsy Inventory-31 (QOLIE-31). Univariate and multivariate linear regression models were used to identify variables associated with QOLIE-31 overall score. Path analysis model was constructed to test for interrelations between the variables.
Results :  Two hundred forty-seven patients completed the questionnaires. By multivariate analysis, in order of degree of contribution, HADS anxiety subscale score, MOS Sleep Scale Sleep Problems Index score, HADS depression subscale score, number of current antiepileptic drugs used, and seizure freedom in the past 4 weeks, significantly correlated with QOLIE-31 overall score, accounting for 65.2% of the variance. Complex interrelationships were present between these factors. A general linear model to predict QOLIE-31 overall score in the presence of these factors was constructed.
Conclusion :  Subjective anxiety, depression, and sleep disturbance exerted greater effect than short-term seizure control on quality of life scores of patients with epilepsy. These factors should be considered simultaneously when evaluating effects of treatment on quality of life.     

Preoperative amygdala fMRI in temporal lobe epilepsy

Purpose:   Anterior temporal lobe resections (ATLR) benefit 70% of patients with refractory mesial temporal lobe epilepsy (TLE), but may be complicated by emotional disturbances. We used functional magnetic resonance imaging (fMRI) to investigate the role of the amygdala in processing emotions in TLE and whether this may be a potential preoperative predictive marker for emotional disturbances following surgery.
Methods:   We studied 54 patients with refractory mesial TLE due to hippocampal sclerosis (28 right, 26 left) and 21 healthy controls using a memory encoding fMRI paradigm, which included viewing fearful and neutral faces. Twenty-one TLE patients (10 left, 11 right) subsequently underwent ATLR. Anxiety and depression were assessed preoperatively and 4 months postoperatively using the Hospital Anxiety and Depression Scale.
Results:   On viewing fearful faces, healthy controls demonstrated left lateralized, while right TLE patients showed bilateral amygdala activation. Left TLE patients had significantly reduced activation in left and right amygdalae compared to controls and right TLE patients. In right TLE patients, left and right amygdala activation was significantly related to preoperative anxiety and depression levels, and preoperative right amygdala activation correlated significantly with postoperative change of anxiety and depression scores, characterized by greater increases in anxiety and depression in patients with greater preoperative activation. No such correlations were seen for left TLE patients.
Discussion:   The fearful face fMRI paradigm is a reliable method for visualizing amygdala activation in controls and patients with mesial TLE. Activation of the right amygdala preoperatively was predictive of emotional disturbances following right ATLR.     

Prevalence of self-reported epilepsy or seizure disorder and its associations with self-reported depression and anxiety: results from the 2004 HealthStyles Survey

PURPOSE: To examine the prevalence of self-reported epilepsy or seizure disorder and its association with self-reported recent depression and anxiety in a large sample of the U.S. adult population. METHODS: We analyzed data from adults aged 18 years or older (n = 4,345) who participated in the 2004 HealthStyles Survey, a large mail panel survey designed to be representative of the U.S. population. RESULTS: Among U.S. adults aged 18 years or older, we estimated that 2.9% have been told by a doctor that they had epilepsy or seizure disorder, and an estimated 1.6% and 0.9% had active and inactive epilepsy, respectively. After controlling for demographic characteristics, we estimated that adults with self-reported epilepsy were twice as likely to self-report depression or anxiety in the previous year as were adults without epilepsy, and adults with active epilepsy were 3 times as likely to self-report depression and twice as likely to have anxiety in the previous year as were adults without epilepsy. CONCLUSIONS: Our findings highlight the burden of self-reported depression and anxiety among adults with self-reported epilepsy or seizure disorder, and suggest that healthcare providers should attempt to determine whether adult patients with epilepsy have any psychiatric comorbidity potentially to improve health outcomes. Questions about epilepsy and related factors should be routinely included on population-based surveys so that we can better understand the epilepsy distribution in the U.S. population and identify the unmet health and psychosocial needs of people with epilepsy.     

Impaired responsibility dimension of self-esteem of Brazilian adolescents with epilepsy

This study aimed to compare the self-esteem of Brazilian adolescents with epilepsy and Brazilian adolescents without this condition and the correlations between self-esteem of these adolescents with depression and anxiety symptoms. Study participants were 101 adolescents of both sexes, aged 10–19 years old, from elementary and high school education. Fifty patients diagnosed with uncomplicated epilepsy attending the pediatric epilepsy clinic of University Hospital composed the case group. The other fifty-one adolescents without this diagnosis were attending public schools in Campinas—SP region. The instruments used were: identification card with demographics and epilepsy data, Multidimensional Self-Esteem Scale, Beck Depression Inventory and Inventory of State-Trait Anxiety - IDATE. A statistically significant result was found in the Responsibility Self-esteem Dimension favoring the control group. Significant correlations between self-esteem scores and anxiety and depression symptoms were also found. The development of a chronic disease such as epilepsy leads to a change in the way the individual perceives himself and the social environment he is inserted, influencing his behavior. The way people with epilepsy experience their seizures is a subjective measure that will control his/her well-being. Childhood and adolescence form the basis for a healthy emotional development; thus, our results show the importance of studying how subjective variables relate to the physical aspects of a chronic disease in these life stages.     

Factors Distinguishing Families of Patients with Psychogenic Seizures from Families of Patients with Epilepsy

Summary: Purpose: Psychogenic seizures (PS) (emotionally based nonelectrical seizures) have been explained by psychodynamics and trauma. However, the family health literature suggests that somatization, of which psychogenic seizures are a form, may run in families and be determined by family patterns of response to distress. This study compared families of patients with PS and those of patients with epilepsy on variables of distress (anxiety and depression) and somatization.
Methods: Eighteen patients (9 with PS and 9 with epilepsy) matched for age and education, and their families answered the Health Status Questionnaire (HSQ), the Weinberger Adjustment Inventory (WAI), the Family Emotional Involvement and Criticism Scale (FEICS), Barsky's Somatization Symptom Inventory (SS), and the Dissociation Experience Scale (DES). Family members' scores were averaged to obtain "family scores."
Results: Patients with PS and those with epilepsy did not differ in any of the measures. However, families of patients with PS reported more health problems, distress, and criticism than did families of patients with epilepsy (p < 0.05). Families of patients with PS had increased criticism and somatic problem scores comparable to those of both types of patients.
Conclusions: Although epilepsy causes patients physical and emotional problems, their families are relatively healthy. In contrast, families of patients with PS are more troubled and may unwittingly contribute to PS through family distress, criticism, and tendencies to somatize.     

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.     

The association between depression and epilepsy in a nationally representative sample

Purpose :  To determine the: (1) national prevalence of epilepsy and depression; (2) prevalence of depression among those with epilepsy; (3) odds ratio of depression among those with epilepsy compared to those without, controlling for demographic characteristics; (4) demographic correlates of depression among those with epilepsy and those without; and, (5) health services utilization of those with epilepsy and depression.
Methods :  The full sample of the nationally representative 2000/2001 Canadian Community Health Survey (n = 130,880) was used to determine prevalence of epilepsy and depression. A subsample of 781 individuals reporting an epilepsy diagnosis and with complete depression data was used to determine prevalence and correlates of depression, and health service utilization patterns. Correlates of depression among those without epilepsy (n = 126,104) were also determined. Chi-square analyses, t -tests, prevalence ratios, and a logistic regression were conducted.
Results :  Thirteen percent of those with epilepsy were depressed, in comparison to 7% of those without (p < 0.001). Epilepsy was associated with 43% higher odds of depression when adjusting for demographic factors. The odds of depression among individuals with epilepsy were higher for females, visible minorities, older individuals, and individuals experiencing food insecurity. Visible minority and older age appear to be unique risk factors for depression in those with epilepsy as compared to those without. Thirty-eight percent of depressed respondents with epilepsy had no consultations with a mental health professional in the previous year.
Discussion :  Medical professionals need to regularly assess levels of depression in their patients with epilepsy. This research helps guide which risk groups should be targeted.     

Differentiating anxiety and depression symptoms in patients with partial epilepsy

Anxiety and depression are separate psychiatric conditions that are often interrelated. This study examines whether they exist independently in this population of patients with partial epilepsy and if they affect all quality-of-life domains. Adult epilepsy patients taking two or more antiepileptic drugs completed a health status survey including demographic items, the Hospital Anxiety and Depression Scale, and the Quality of Life in Epilepsy-10 (QOLIE-10). The questionnaire was completed by 201 epilepsy patients. Symptom prevalences of anxiety (52% none, 25% mild, 16% moderate, 7% severe) and depression (62% none, 20% mild, 14% moderate, 4% severe) were high. All health-related quality-of-life (HRQOL) domains worsened significantly with increasing levels of anxiety and depression: Total QOLIE-10 scores decreased from 72+/-18 in patients with no anxiety to 54+/-13 in those with mild, 48+/-18 in those with moderate, and 40+/-23 in those with severe anxiety (P<0.0001). Total QOLIE-10 scores decreased from 70+/-16 in patients with no depression to 50+/-16 in those with mild, 45+/-16 in those with moderate, and 24+/-21 in those with severe depression (P<0.0001). No significant difference in anxiety scores was observed controlling for seizure frequency or epilepsy duration. Regression analyses showed that anxiety and depression account for different proportions of variance as predictors of HRQOL (R2=0.337 (anxiety) and 0.511 (depression)). The data suggest that patients may benefit from increased attention to the role of anxiety separately from depression.     

Psychosocial issues in people with epilepsy in Togo and Benin (West Africa) I. Anxiety and depression measured using Goldberg's scale

PURPOSE: This study in Togo and Benin, West Africa, was aimed at measuring depression and anxiety among people with epilepsy (PWE). METHODS: This cross-sectional study of 281 adult PWE in Togo and 215 in Benin matched with the same number of controls without epilepsy used Goldberg's anxiety and depression scale. The statistical tests used for comparisons were chi(2) tests, Fisher's exact test, analysis of variance, and Fisher's PLSD test when necessary. RESULTS: PWE in Togo and Benin had significantly higher (P<0.0001) average depression scores (4.4+/-2.1, 4.7+/-2.7) than controls (0.5+/-0.9, 1.4+/-2.4). They also had significantly higher (P<0.0001) average anxiety scores (5.3+/-2.0, 6.2+/-2.1) than controls (2.5+/-1.6, 1.6+/-2.0). In consideration of the thresholds of the scale, the prevalence of possible major anxiety and depression among PWE was also very high compared with controls (P<0.0001). High anxiety and depression scores were, in general, positively correlated with a higher frequency of seizures and lack of treatment. CONCLUSION: Results confirmed the existence of anxiety and depression among PWE in Togo and Benin.
