Psychological treatments for epilepsy

Evaluation of Fear in Idiopathic Epilepsy Using Population-Based Survey and Bhalla-Gharagozli Fear in Epilepsy Questionnaire (BG-FEQ)

INTRODUCTION

The primary objective of this study was to evaluate fear related to epilepsy and its treatment among those with idiopathic epilepsy. Our secondary objective was to estimate the psychometric properties of a brief Bhalla-Gharagozli Fear in epilepsy Questionnaire (BG-FEQ).

METHODS

We conducted patient-finding exercise in our study areas through various means to obtain subjects with idiopathic epilepsy. We carefully examined each patient through a detailed case-history examination. Following that, we evaluated fear related to epilepsy by using Bhalla-Gharagozli Fear in Epilepsy Questionnaire (BG-FEQ) across two broad domains: epilepsy and pharmacotherapy.

RESULTS

The study obtained 52 subjects (39.0 years; 45.0% males, 70.0% married, 35.0% unqualified, 85.0% active epilepsy, 80.0% generalized seizures) with idiopathic epilepsy. The alpha coefficient was 92.8, with no item-specific coefficient of ≤0.91. The alpha coefficient was 0.90 and 0.93 for reporting a "yes" and "no" to the items, respectively. We obtained a two-factor structure of BG-FEQ that provided a cumulative variance of 83.6%. The majority (65.0%) reported at least one fear. The per-patient mean number of the fear element was 2.1 (95% CI 1.1-3.3), which differed significantly for males and females (1.1, 95% CI 0.4-2.6 and 3.0, 95% CI 1.4-4.6, respectively, p=0.03). The most frequent fear was that of addiction and the bad effects of anti-seizure medications (both 45.0%). Upon bootstrap regression after constraining gender, the fear elements were associated with illiteracy, difficulty in understanding epilepsy and sleeping in a prone position. The sample power was 99.0%.

CONCLUSION

There was a significant representation of fear among those with idiopathic epilepsy, especially among the females, particularly the fear of brain tumour, premature death and more frequent/severe seizures over time. At least 65.0% of idiopathic subjects are likely to be affected by at least one fear. The essential mitigating approach should be the education of practitioners towards better identification and therapeutic handling of comorbid constructs, and also for the education of patients and their caregivers towards better awareness and prevention. There is also a need for formal Epilepsy Educators towards better awareness, therapeutic support and prevention of epilepsy.

Do distance-delivery group interventions improve depression in people with epilepsy?

About one-third of people with epilepsy experience comorbid depression. The present study examined outcomes of a distance-delivery group intervention program designed to improve emotional well-being. Participants were 55 adults with epilepsy and self-reported depressive symptoms who were randomly assigned to take part in either a mindfulness-based cognitive behavioral therapy (CBT) program (UPLIFT, n = 20), an epilepsy information and self-management program (EpINFO, n = 24) that served as an active control group, or a wait-list control (WLC) group (n = 11). The Quick Inventory of Depressive Symptomatology (QIDS), Neurological Disorders Depression Inventory for Epilepsy (NDDIE), and the psychological health subscale of the World Health Organization Quality of Life (WHOQOL-BREF) scale were used to assess depression and psychological quality of life before and after treatment, and at short-term (six months) and long-term follow-up (one year) upon program completion. From pre- to posttreatment, a main effect of time was found, with participants in both the UPLIFT and EpINFO groups having reported to a similar degree a significant decrease in depressive symptoms and improved psychological health, improvements that were not seen in the WLC group. The time by group interaction effect was not significant. The effects seen at posttreatment in the UPLIFT and EpINFO groups remained at six months and one year after treatment. These data suggest that distance-delivery group intervention programs are effective at improving depression and psychological quality of life, with the EpINFO program offering benefits similar to the UPLIFT program.

Neural response to stress and perceived stress differ in patients with left temporal lobe epilepsy

Patients with epilepsy are often able to predict seizure occurrence subsequent to an acute stress experience. However, neuroimaging investigations into the neural basis of this relationship or the potential influence of perceived life stress are limited. The current study assessed the relationship between perceived stress and the neurobehavioral response to stress in patients with left temporal lobe epilepsy (LTLE) and healthy controls (HCs) using heart rate, salivary cortisol level, and functional magnetic resonance imaging and compared these effects between HCs and LTLE. Matched on perceived stress levels, groups of 36 patients with LTLE and 36 HCs completed the Montreal Imaging Stress Task, with control and stress math task conditions. Among LTLEs, 27 reported that prior (acute) stress affected their seizures (LTLES+), while nine did not (LTLES-). The results revealed that increased perceived stress was associated with seizure frequency in LTLE. Further, cortisol secretion was greater in LTLE, but did not vary with perceived stress as observed in HCs. A linear mixed-effects analysis revealed that as perceived stress increased, activation in the hippocampal complex (parahippocampal gyrus and hippocampus) decreased during stressful math in the LTLES+, increased in HCs, but did not vary in the LTLES-. Task-based functional connectivity analyses revealed LTLE differences in hippocampal functional connectivity with sensory cortex specific to stressor modalities. We argue that the current study demonstrates an inhibitory hippocampal mechanism underlying differences in resilience to stress between HCs and LTLE, as well as LTLE patients who report stress as a precipitant of seizures.

Clinic-Based Mobile Health Decision Support to Enhance Adult Epilepsy Self-Management: An Intervention Mapping Approach

INTRODUCTION

Epilepsy is a neurological disorder involving recurrent seizures. It affects approximately 5 million people in the U.S. To optimize their quality of life people with epilepsy are encouraged to engage in self-management (S-M) behaviors. These include managing their treatment (e.g., adhering to anti-seizure medication and clinical visit schedules), managing their seizures (e.g., responding to seizure episodes), managing their safety (e.g., monitoring and avoiding environmental seizure triggers), and managing their co-morbid conditions (e.g., anxiety, depression). The clinic-based Management Information Decision Support Epilepsy Tool (MINDSET) is a decision-support system founded on theory and empirical evidence. It is designed to increase awareness by adult patients (≥18 years) and their health-care provider regarding the patient's epilepsy S-M behaviors, facilitate communication during the clinic visit to prioritize S-M goals and strategies commensurate with the patient's needs, and increase the patient's self-efficacy to achieve those goals.

METHODS

The purpose of this paper is to describe the application of intervention mapping (IM) to develop, implement, and formatively evaluate the clinic-based MINDSET prototype and in developing implementation and evaluation plans. Deliverables comprised a logic model of the problem (IM Step 1); matrices of program objectives (IM Step 2); a program planning document comprising scope, sequence, theory-based methods, and practical strategies (IM Step 3); a functional MINDSET program prototype (IM Step 4); plans for implementation (IM Step 5); and evaluation (IM Step 6). IM provided a logical and systematic approach to developing and evaluating clinic-based decision support toward epilepsy S-M.

Non-pharmacological interventions for people with epilepsy and intellectual disabilities

BACKGROUND

Approximately 30% of patients with epilepsy remain refractory to drug treatment and continue to experience seizures whilst taking one or more antiepileptic drugs (AEDs). Several non-pharmacological interventions that may be used in conjunction with or as an alternative to AEDs are available for refractory patients. In view of the fact that seizures in people with intellectual disabilities are often complex and refractory to pharmacological interventions, it is evident that good quality randomised controlled trials (RCTs) are needed to assess the efficacy of alternatives or adjuncts to pharmacological interventions.This is an updated version of the original Cochrane review (Beavis 2007) published in The Cochrane Library (2007, Issue 4).

OBJECTIVES

To assess data derived from randomised controlled trials of non-pharmacological interventions for people with epilepsy and intellectual disabilities.Non-pharmacological interventions include, but are not limited to, the following.• Surgical procedures.• Specialised diets, for example, the ketogenic diet, or vitamin and folic acid supplementation.• Psychological interventions for patients or for patients and carers/parents, for example, cognitive-behavioural therapy (CBT), electroencephalographic (EEG) biofeedback and educational intervention.• Yoga.• Acupuncture.• Relaxation therapy (e.g. music therapy).

SEARCH METHODS

For the latest update of this review, we searched the Cochrane Epilepsy Group Specialised Register (19 August 2014), the Cochrane Central Register of Controlled Trials (CENTRAL) via CRSO (19 August 2014), MEDLINE (Ovid, 1946 to 19 August 2014) and PsycINFO (EBSCOhost, 1887 to 19 August 2014).

SELECTION CRITERIA

Randomised controlled trials of non-pharmacological interventions for people with epilepsy and intellectual disabilities.

DATA COLLECTION AND ANALYSIS

Two review authors independently applied the inclusion criteria and extracted study data.

MAIN RESULTS

One study is included in this review. When two surgical procedures were compared, results indicated that corpus callosotomy with anterior temporal lobectomy was more effective than anterior temporal lobectomy alone in improving quality of life and performance on IQ tests among people with epilepsy and intellectual disabilities. No evidence was found to support superior benefit in seizure control for either intervention. This is the only study of its kind and was rated as having an overall unclear risk of bias. The previous update (December 2010) identified one RCT in progress. The study authors have confirmed that they are aiming to publish by the end of 2015; therefore this study (Bjurulf 2008) has not been included in the current review.

AUTHORS' CONCLUSIONS

This review highlights the need for well-designed randomised controlled trials conducted to assess the effects of non-pharmacological interventions on seizure and behavioural outcomes in people with intellectual disabilities and epilepsy.

Is it time to act? The potential of acceptance and commitment therapy for psychological problems following acquired brain injury

Behaviour therapies have a well-established, useful tradition in psychological treatments and have undergone several major revisions. Acceptance and Commitment Therapy (ACT) and mindfulness-based approaches are considered a third wave of behavioural therapies. Emerging evidence for ACT has demonstrated that this paradigm has promising effectiveness in improving functionality and well-being in a variety of populations that have psychological disturbances and/or medical problems. In this review we first evaluate traditional cognitive behavioural therapy (CBT) interventions used to manage psychological problems in distressed individuals who have sustained an acquired brain injury (ABI). We provide an overview of the ACT paradigm and the existent evidence base for this intervention. A rationale is outlined for why ACT-based interventions may have potential utility in assisting distressed individuals who have sustained a mild to moderate ABI to move forward with their lives. We also review emerging evidence that lends preliminary support to the implementation of acceptance and mindfulness-based interventions in the rehabilitation of ABI patient groups. On the basis of existent literature, we recommend that it is an opportune time for forthcoming research to rigorously test the efficacy of ACT-based interventions in facilitating ABI patient groups to re-engage in living a valued and meaningful life, in spite of their neurocognitive and physical limitations. The promising utility of testing the efficacy of the ACT paradigm in the context of multimodal rehabilitation programmes for ABI populations is also addressed.

WITHDRAWN: Self-management education for adults with epilepsy

BACKGROUND

Self-management education has been shown to improve the quality of life of people with chronic illnesses. It has been suggested that self-management education may improve seizure control and other outcomes in people with epilepsy.

OBJECTIVES

To review systematically the research literature on the effectiveness of self-management education in improving health outcomes for adults with epilepsy.

SEARCH STRATEGY

We searched MEDLINE (Ovid) (1966 to April 2005), EMBASE (Ovid) (1980 to April 2005), CINAHL (Dialog) (1980 to April 2005), PsycINFO (Dialog) (1887 to April 2005), and the Cochrane Epilepsy Group's Specialised Register (April 2005). We also handsearched Epilepsia and conference abstracts and proceedings. Experts in the field were contacted to identify any additional trials. We did not impose any language restriction. We re-ran the searches in February 2007 and added the identified references to the 'Studies awaiting assessment' table.

SELECTION CRITERIA

Randomised trials of self-management education programmes for adults with epilepsy.

DATA COLLECTION AND ANALYSIS

At least two review authors independently assessed the quality of each study and extracted data.

MAIN RESULTS

Two trials evaluated the effect of self-management education for adults with epilepsy, neither of which assessed as being of high quality. In total, 483 adults with epilepsy were randomised. Both trials showed improvements in seizure frequency and other outcomes, such as knowledge. However, we were not able to estimate a summary effect for seizure frequency due to a lack of data.

AUTHORS' CONCLUSIONS

Self-management education programmes, based on increasing understanding through psychosocial methods, may improve knowledge about epilepsy, certain behavioural outcomes, and reduce seizure frequency. It is, however, not clear how effective self-management programmes of epilepsy would be in a more general population of adults with epilepsy, as both trials had higher proportions of people with partial seizures than would be expected in a community sample.

WITHDRAWN: Self-management education for children with epilepsy

BACKGROUND

Self-management education has been shown to improve the quality of life of children and young people with chronic illnesses. It has been suggested that self-management education may improve seizure control and other outcomes in children and young people with epilepsy.

OBJECTIVES

To review systematically the research literature on the effectiveness of self-management education in improving health outcomes for children and young people with epilepsy.

SEARCH STRATEGY

We searched the Cochrane Epilepsy Group's Specialised Register (February 2007), MEDLINE (Ovid) (1966 to February 2007), EMBASE (Ovid) (1980 to February 2007), CINAHL (Dialog) (1980 to February 2007), and PsycINFO (Dialog) (1887 to February 2007). We also handsearched Epilepsia and conference abstracts and proceedings. Experts in the field were contacted to identify any additional trials. No language restriction was imposed.

SELECTION CRITERIA

Randomised trials of self-management education programmes for children or young people with epilepsy.

DATA COLLECTION AND ANALYSIS

At least two review authors independently assessed the quality of each study and extracted data.

MAIN RESULTS

Only one trial involving 167 children was identified that evaluated the effect of a child-centred model of training for the self-management of two chronic illnesses, asthma and epilepsy. The trial was not assessed as being of high quality and the methods used to analyse and report the data did not enable us to precisely determine the effect of the intervention. However, improvements were seen in seizure frequency and other outcomes, such as knowledge and behaviour.

AUTHORS' CONCLUSIONS

Self-management education programmes that deliver a child-centred model of training, may improve knowledge about epilepsy, certain behavioural outcomes, and reduce seizure frequency in children and young people with epilepsy. However, based on the evidence reviewed, we are not able to determine how effective it is, or what the key components of the programme should be.

How should clinical psychologists approach complementary and alternative medicine? Empirical, epistemological, and ethical considerations

As complementary and alternative medicine (CAM) practices are often recommended for mental health problems, many clients in clinical psychology will be in receipt of such treatments from other practitioners. Some psychologists have argued that CAM and psychology are natural bedfellows, given their sharing of philosophies (e.g., holism), professional orientations (e.g., person-centeredness), and theoretical positions (e.g., mind-body connectionism). It has specifically been argued that the practices of CAM could productively be appropriated, or at least promoted, by clinical psychologists. However, other commentators have criticized CAM for comprising therapies that, by definition, are both intrinsically unscientific and lacking in empirical evidence. This article examines the current standing of CAM from empirical, epistemological, and ethical perspectives. CAM treatments are found to be based on heterogeneous epistemologies and to suffer from poor records in empirical efficacy research. Attention is given to possible psychological explanations for CAM's popularity in the face of poor evidence for efficacy. It is argued that, given the likely incompatibility of CAM with clinical psychology's positivist scientific ethos, CAM practices should not be integrated into clinical psychology at this time.

Nonpharmacological treatment options for epilepsy

Approximately one third of children with epilepsy have persistent seizures despite trials of multiple antiepileptic medications. For some of these patients, epilepsy surgery may provide freedom from seizures. However, in many cases, epilepsy surgery is not a viable treatment option. Nonpharmacological approaches are a useful adjunct to help manage seizures in these children. This review examines the role of vagus nerve stimulation, the ketogenic diet, and various forms of EEG biofeedback therapy in children with intractable epilepsy. Although the mechanism of action is not known precisely for any of these adjunctive therapies, they add an important and evolving dimension to the management of difficult to control epilepsy in children. In addition, pyridoxine-dependent seizures are discussed as an example of an etiology of refractory seizures that responds well to replacement therapy.
