Self-compassion and depression, anxiety, and resilience in adults with epilepsy.

BACKGROUND: Research suggests that people with epilepsy (PWE) are more likely to experience depression and anxiety than the general population. Given the adversity associated with the condition, resilience may also be important. However, to date, resilience has been largely overlooked in the epilepsy literature. Self-compassion has been widely associated with improved psychological wellbeing and, to a lesser extent, resilience. However, the relationship between self-compassion and depression, anxiety, and resilience in PWE has not been examined. OBJECTIVES: Using a quantitative cross-sectional survey design, the aim of the present study was to examine the extent to which self-compassion predicted depression, anxiety, and resilience when controlling for demographic and illness-related variables. METHODS: Adults with epilepsy were invited to take part in a survey online or in epilepsy or neurology clinics. Two-hundred and seventy participants completed the survey, and data were analyzed using hierarchical multiple regression models. RESULTS: In this sample of PWE, self-compassion significantly predicted lower depression and anxiety and higher resilience when other significant sociodemographic and illness-related variables had been taken into account. CONCLUSIONS: The findings of the present study indicate that self-compassion could be an important factor in determining psychological outcomes for adults with epilepsy, and its role is worthy of further exploration to help improve psychological outcomes for PWE.

Revealing the Dynamic Modulations That Underpin a Resilient Neural Network for Semantic Cognition: An fMRI Investigation in Patients With Anterior Temporal Lobe Resection.

One critical feature of any well-engineered system is its resilience to perturbation and minor damage. The purpose of the current study was to investigate how resilience is achieved in higher cognitive systems, which we explored through the domain of semantic cognition. Convergent evidence implicates the bilateral anterior temporal lobes (ATLs) as a conceptual knowledge hub. While bilateral damage to this region produces profound semantic impairment, unilateral atrophy/resection or transient perturbation has a limited effect. Two neural mechanisms might underpin this resilience to unilateral ATL damage: 1) the undamaged ATL upregulates its activation in order to compensate; and/or 2) prefrontal regions involved in control of semantic retrieval upregulate to compensate for the impoverished semantic representations that follow from ATL damage. To test these possibilities, 34 postsurgical temporal lobe epilepsy patients and 20 age-matched controls were scanned whilst completing semantic tasks. Pictorial tasks, which produced bilateral frontal and temporal activation, showed few activation differences between patients and control participants. Written word tasks, however, produced a left-lateralized activation pattern and greater differences between the groups. Patients with right ATL resection increased activation in left inferior frontal gyrus (IFG). Patients with left ATL resection upregulated both the right ATL and right IFG. Consistent with recent computational models, these results indicate that 1) written word semantic processing in patients with ATL resection is supported by upregulation of semantic knowledge and control regions, principally in the undamaged hemisphere, and 2) pictorial semantic processing is less affected, presumably because it draws on a more bilateral network.

Correlates of stigma in adults with epilepsy: A systematic review of quantitative studies.

OBJECTIVES: The aim of this review was to identify quantitative correlates, predictors, and outcomes of stigma in adults with epilepsy living in Western countries. METHODS: To identify relevant literature, four academic databases (PsycINFO, CINAHL, PubMed, and Scopus) were systematically searched using key terms related to stigma and epilepsy. RESULTS: Thirty-three research papers reporting findings from 25 quantitative studies of correlates of stigma in epilepsy were identified. The findings suggest that stigma can be predicted by demographic, illness-related, and psychosocial factors, although associations were found to be highly culturally specific. Outcomes of stigma in people with epilepsy were replicated more consistently across cultures, and its impact was significant. Detrimental effects included both worse physical health, including less effective management of the condition, and reduced psychological well-being, including difficulties such as depression and anxiety. IMPLICATIONS: Educational initiatives and therapeutic interventions that aim to address stigma in people with epilepsy are recommended; however, these need to be culturally informed to ensure that they are valid and effective.

The Roles of Left Versus Right Anterior Temporal Lobes in Semantic Memory: A Neuropsychological Comparison of Postsurgical Temporal Lobe Epilepsy Patients.

The presence and degree of specialization between the anterior temporal lobes (ATLs) is a key issue in debates about the neural architecture of semantic memory. Here, we comprehensively assessed multiple aspects of semantic cognition in a large group of postsurgical temporal lobe epilepsy (TLE) patients with left versus right anterior temporal lobectomy (n = 40). Both subgroups showed deficits in expressive and receptive verbal semantic tasks, word and object recognition, naming and recognition of famous faces and perception of faces and emotions. Graded differences in performance between the left and right groups were secondary to the overall mild semantic impairment; primarily, left resected TLE patients showed weaker performance on tasks that required naming or accessing semantic information from a written word. Right resected TLE patients were relatively more impaired at recognizing famous faces as familiar, although this effect was observed less consistently. These findings unify previous partial, inconsistent results and also align directly with fMRI and transcranial magnetic stimulation results in neurologically intact participants. Taken together, these data support a model in which the 2 ATLs act as a coupled bilateral system for the representation of semantic knowledge, and in which graded hemispheric specializations emerge as a consequence of differential connectivity to lateralized speech production and face perception regions.

Predicting the psychosocial outcome of epilepsy surgery: A longitudinal perspective on the 'burden of normality'.

Good seizure outcomes and good psychosocial outcomes following epilepsy surgery do not necessarily follow one from the other. This study explored the relationship between several presurgical psychosocial characteristics and postsurgical quality-of-life outcomes. The study aimed to develop the concept of 'the burden of normality' and identify risk factors for a poor psychosocial outcome that could be targeted with ameliorative presurgery cognitive behavioral techniques. Data were collected from 77 epilepsy surgery patients from three UK epilepsy centers and presurgery and postsurgery follow-up data were obtained from 30-34 patients, depending on the measure. Measures were self-report. Postsurgery intervals were determined by the epilepsy surgery care pathway at individual centers. Presurgery poor levels of mental health, poor social functioning, increased belief in illness chronicity, and associating epilepsy with social role limitations were all associated with poor postsurgical quality of life. Adopting an accepting coping strategy presurgery was associated with good postoperative quality of life. Regression analysis showed that a good postsurgical quality of life was positively predicted by a presurgical coping style of being able to make the best of a situation and see challenges in a positive light (i.e., positive reinterpretation and growth from the COPE scale) and negatively predicted by presurgical levels of anxiety. These data are presented as an important step in identifying psychological red flags for an adverse psychosocial outcome to epilepsy surgery, as exemplified by the concept of the 'burden of normality' and specifying targets for preoperative ameliorative psychological advice.

Neuropsychological profiles of patients with juvenile myoclonic epilepsy and their siblings: An extended study.

OBJECTIVE: To examine executive function, intelligence, visuospatial skills, language, memory, attention, reaction time, anxiety, depression, and emotional and behavioral traits most frequently associated with executive dysfunction in patients with juvenile myoclonic epilepsy (JME) compared with a sibling and a normal control group under video-electroencephalography (video-EEG) conditions. METHODS: Twenty-two sibling pairs, one with JME, were compared with 44 controls matched for age, gender, and educational level. All participants were administered a comprehensive set of neuropsychological and questionnaire measures during and without video-EEG recording. RESULTS: The JME group differed significantly from controls in measures of phonemic and semantic verbal fluency. They scored significantly higher on the dysexecutive self-rating questionnaire, being more likely to report traits associated with executive dysfunction than both siblings and controls. Patients with JME reported significantly low mood than both controls and their siblings. Unaffected siblings differed significantly from controls on psychomotor speed, phonemic verbal fluency and were considered to exhibit traits associated with executive dysfunction by others. Qualitative inspection of data suggested a convincing trend for patients with JME and their siblings to perform worse than controls on most measures. SIGNIFICANCE: This study supports the existence of a distinct neuropsychological profile among patients with JME and their siblings, which is likely to be genetically determined. The similarity of neuropsychological profiles between JME patients and their siblings is independent of antiepileptic drug effects or subclinical EEG activity. The significant differences between the sibling and controls suggests that there is a neurocognitive endophenotype for JME.

Erectile function, sexual desire, and psychological well-being in men with epilepsy.

OBJECTIVE: The aim of this study was to explore the effects of anxiety, depression, and self-reported quality of life (QOL) on sexual function of men with epilepsy (MWE). METHODS: Sixty-nine MWE taking one antiepileptic drug and 50 controls were recruited. All completed sexual function questionnaires, the Hospital Anxiety and Depression Scale (HADS), and the World Health Organization Brief Quality of Life Questionnaire (WHOQOL-BREF). Blood was taken to analyze testosterone and dihydroepiandrosterone sulfate levels. RESULTS: Compared with controls, MWE reported higher levels of anxiety, depression, and psychological distress; lower overall quality of life and health; and lower levels of sexual desire and erectile function. Seizure frequency did not affect any of these variables, and testosterone levels did not correlate with sexual desire or erectile function. Simple linear regression showed a significant negative correlation between sexual desire and indices of anxiety, depression, and psychological distress. Multiple linear regression using overall QOL as dependent variable showed that anxiety, depression, psychological distress, and the Psychological Well-Being subscale of the WHOQOL-BREF predicted 48% of its variability. Interestingly, sexual function and seizure status did not. CONCLUSION: MWE reported lower levels of sexual desire and were more likely to report erectile dysfunction than controls. But the most important determinant of QOL was psychological status, not seizure frequency or sexual function.

Neuropsychological profiles of patients with juvenile myoclonic epilepsy and their siblings: a preliminary controlled experimental video-EEG case series.

OBJECTIVE: The aim of this study was to examine expressive language, memory, and higher executive tasks in patients with juvenile myoclonic epilepsy (JME) as compared with their siblings and a normal control group under video-EEG conditions. METHODS: Eight sibling pairs, one in each pair with JME, were compared with 16 controls matched for age, sex, ethnicity, and educational level. The participants were administered a standard comprehensive set of neuropsychological measures to assess emotional well-being, intelligence, memory, language, visuospatial skills, reaction time, attention, and higher executive function, during and without video-EEG recording. RESULTS: The JME group differed significantly from controls on measures of phonemic and semantic verbal fluency. They also scored significantly higher on the Dysexecutive Questionnaire, being much more likely to report traits associated with executive dysfunction. Qualitative inspection of the data suggested a trend for patients with JME and their siblings to perform worse than controls on some measures, notably those of expressive language and higher executive function, but on other measures the differences were not statistically significant. In contrast, the JME and sibling group performed as well as controls on the Rey Complex Figure and other tests of visuospatial skills. CONCLUSION: The present controlled experimental case series provides support for a neuropsychological profile of patients with JME and their siblings. Significant impairments in verbal and executive functioning may have important ramifications for the social, occupational, and academic performance of people with JME. The apparent corresponding likeness in cognitive performance, exhibited independent of EEG activity, between patients with JME and their siblings warrants further exploration as similar cortical and subcortical structures may be implicated in these two groups.

The base rate of Wada test failure.

Although functional brain imaging can lateralize language functioning and has the potential to assess the functional integrity of the mesial temporal lobe memory structures, imaging protocols are not currently available for clinical use. Assessing the risk of post-epilepsy surgery memory decline is an important part of treatment planning, and the Wada test remains the current technique. The Wada test is invasive and has limitations with respect to sensitivity and specificity. We describe an audit of 141 consecutive Wada test results looking at the base rate of failure and clinical characteristics of failure. The objective was to provide base rate data that support decision making regarding selective use of the Wada test. We conclude that right-handed patients with right temporal lesions who have strong verbal memory are very unlikely to fail and probably do not need to undergo the Wada test. Patients with left temporal lesions are more likely to fail regardless of handedness and regardless of baseline neuropsychological test data. We propose that until functional imaging protocols become available to supersede the Wada test, patients should be considered for the Wada test on a case-by-case basis.

Sexual function in men with epilepsy: how important is testosterone?

OBJECTIVE: To ascertain the effects on sexual function of men with epilepsy (MWE) of testosterone levels and indices of anxiety and depression. METHODS: Sixty MWE taking one antiepileptic drug only (AED), with no comedication, were compared with 60 control men. Total testosterone (TT), free testosterone (FT), bioactive testosterone (BAT), dehydroepiandrosterone sulfate (DHEAS), androstenedione, and sex hormone-binding globulin (SHBG) were measured. Each man also completed validated questionnaires exploring sexual desire (Sexual Desire Inventory [SDI]), sexual response (Sexual Response Inventory [SRI]), erectile function (Sexual Self-Efficacy Scale [SSES]), and anxiety and depression (Hospital Anxiety and Depression Scale). RESULTS: MWE reported lower levels of sexual desire and lower erectile function compared with controls. They had significantly higher levels of anxiety, depression, and psychological distress. MWE had significantly higher SHBG levels and significantly lower DHEAS. There were no significant differences between the groups' TT, FT, or BAT levels. BAT levels were significantly lower in men taking enzyme-inducing AEDs than in those taking non-enzyme-inducing AEDs. Visual inspection of TT and BAT levels showed that the majority of MWE and controls had TT and BAT levels above the "androgen threshold" levels of 12 nmol/L TT or 3.8 nmol/L BAT considered necessary for normal sexual function. There was a significant correlation (Spearman rank and simple linear regression) between sexual function and indices of anxiety and depression. There was no significant relationship between SDI and SSES and TT, FT, or BAT (Spearman rank correlation). CONCLUSIONS: Concentrating on hormone levels alone as an explanation of sexual dysfunction in epilepsy represents an overly simplistic approach to the problem. Future studies should include measures of quality of life, anxiety, and depression.
