Abstract
BACKGROUND Given the degenerative nature of the condition, people living with motor neuron disease (MND) experience high levels of psychological distress. The purpose of this research was to investigate the cost-effectiveness of acceptance and commitment therapy (ACT), adapted for the specific needs of this population, for improving quality of life. METHODS A trial-based cost-utility analysis over a 9-month period was conducted comparing ACT plus usual care (n = 97) versus usual care alone (n = 94) from the perspective of the National Health Service. In the primary analysis, quality-adjusted life years (QALYs) were computed using health utilities generated from the EQ-5D-5L questionnaire. Sensitivity analyses and subgroup analyses were also carried out. RESULTS Difference in costs was statistically significant between the two arms, driven mainly by the intervention costs. Effects measured by EQ-5D-5L were not statistically significantly different between the two arms. The incremental cost-effectiveness was above the £20,000 to £30,000 per QALY gained threshold used in the UK. However, the difference in effects was statistically significant when measured by the McGill Quality of Life-Revised (MQOL-R) questionnaire. The intervention was cost-effective in a subgroup experiencing medium deterioration in motor neuron symptoms. CONCLUSIONS Despite the intervention being cost-ineffective in the primary analysis, the significant difference in the effects measured by MQOL-R, the low costs of the intervention, the results in the subgroup analysis, and the fact that ACT was shown to improve the quality of life for people living with MND, suggest that ACT could be incorporated into MND clinical services.

Abstract
BACKGROUND Differences in affective processing have previously been shown in functional neurological disorder (FND); however, the mechanistic relevance is uncertain. We tested the hypotheses that highly arousing affective stimulation would result in elevated subjective functional neurological symptoms (FNS), and this would be associated with elevated autonomic reactivity. The possible influence of cognitive detachment was also explored. METHOD Individuals diagnosed with FND (motor symptoms/seizures; n=14) and healthy controls (n=14) viewed Positive, Negative and Neutral images in blocks, while passively observing the stimuli ('Watch') or detaching themselves ('Distance'). The FND group rated their primary FNS, and all participants rated subjective physical (arousal, pain, fatigue) and psychological states (positive/negative affect, dissociation), immediately after each block. Skin conductance (SC) and heart rate (HR) were monitored continuously. RESULTS FNS ratings were higher after Negative compared with Positive and Neutral blocks in the FND group (p=0.002, ηp 2=0.386); however, this effect was diminished in the Distance condition relative to the Watch condition (p=0.018, ηp 2=0.267). SC and/or HR correlated with FNS ratings in the Negative-Watch and Neutral-Distance conditions (r values=0.527-0.672, p values=0.006-0.035). The groups did not differ in subjective affect or perceived arousal (p values=0.541-0.919, ηp 2=<0.001-0.015). CONCLUSIONS Emotionally significant events may exert an influence on FNS which is related to autonomic activation rather than altered subjective affect or perceived arousal. This influence may be modulated by cognitive detachment. Further work is needed to determine the relevance and neural bases of these processes in specific FND phenotypes.

Abstract
OBJECTIVE This study examined etiological factors and symptom triggers of functional motor symptoms (FMS) or functional seizures (FS) and assessed potential relationships with relevant clinical features (i.e., functional symptoms, quality of life, and general functioning). METHODS Seventeen participants with FMS or FS and 17 healthy control participants underwent an in-depth clinical interview and completed questionnaires assessing adverse life events, psychological and physical symptoms, alexithymia, autistic traits, illness perceptions, health-related quality of life (HRQoL), and work and social functioning. RESULTS Participants with FMS or FS perceived various causes of the disorder, including physical symptoms (65%), emotional problems (53%), adverse life events (47%), and work-related factors (29%). Triggers of FMS and FS included physical activity or exertion (59%), stress and emotions (59%), sensory experiences (47%), and fatigue (41%). Compared with healthy control participants, participants with FMS or FS reported more adverse events during adolescence and higher levels of alexithymia, somatoform dissociation, psychological dissociation (disengagement, depersonalization, and derealization), anxiety, depression, and physical symptoms. Participants with FMS or FS had worse HRQoL than healthy control participants and impaired work and social functioning. There were inverse associations between HRQoL scores and somatoform dissociation, anxiety, and adverse life events. CONCLUSIONS Participants with FMS or FS reported diverse biopsychosocial etiological factors and symptom triggers. Ongoing psychological symptoms and lifetime adverse experiences were associated with worse HRQoL. Future studies will examine these factors in larger samples of individuals with FMS or FS to better understand their shared and distinct etiological underpinnings.

Abstract
Objective: This systematic review provides an updated summary of the existing literature on the validity of screening tools for cognitive and behavioral impairment in people with Amyotrophic Lateral Sclerosis (pwALS), and also focuses on their reliability. Method: The following cognitive and behavioral screening tools were assessed in this review: the Edinburgh Cognitive and Behavioral ALS Screen (ECAS); the ALS Cognitive Behavioral Screen (ALS-CBS), the Mini Addenbrooke's Cognitive Examination (Mini-ACE), the Beaumont Behavioral Interview (BBI); the MND Behavior Scale (MiND-B); and the ALS-FTD Questionnaire (ALS-FTD-Q). A search, using Medline, PsychINFO and Embase (21/09/2023), generated 37 results after exclusion criteria were applied. Evidence of internal consistency, item-total correlations, inter-rater reliability, clinical validity, convergent validity, and structural validity were extracted and assessed and risk of bias was evaluated. Results: The cognitive component of the ECAS was the tool with most evidence of reliability and validity for the assessment of cognitive impairment in ALS. It is well-suited to accommodate physical symptoms of ALS. For behavioral assessment, the BBI or ALS-FTD-Q had the most evidence of reliability and validity. The BBI is more thorough, but the ALS-FTD-Q is briefer. Conclusions: There is good but limited evidence for the reliability and validity of cognitive and behavioral screens. Further evidence of clinical and convergent validity would increase confidence in their clinical and research use.

Abstract
BACKGROUND We compared dissociative seizure specific cognitive behavior therapy (DS-CBT) plus standardized medical care (SMC) to SMC alone in a randomized controlled trial. DS-CBT resulted in better outcomes on several secondary trial outcome measures at the 12-month follow-up point. The purpose of this paper is to evaluate putative treatment mechanisms. METHODS We carried out a secondary mediation analysis of the CODES trial. 368 participants were recruited from the National Health Service in secondary / tertiary care in England, Scotland, and Wales. Sixteen mediation hypotheses corresponding to combinations of important trial outcomes and putative mediators were assessed. Twelve-month trial outcomes considered were final-month seizure frequency, Work and Social Adjustment Scale (WSAS), and the SF-12v2, a quality-of-life measure providing physical (PCS) and mental component summary (MCS) scores. Mediators chosen for analysis at six months (broadly corresponding to completion of DS-CBT) included: (a) beliefs about emotions, (b) a measure of avoidance behavior, (c) anxiety and (d) depression. RESULTS All putative mediator variables except beliefs about emotions were found to be improved by DS-CBT. We found evidence for DS-CBT effect mediation for the outcome variables dissociative seizures (DS), WSAS and SF-12v2 MCS scores by improvements in target variables avoidance behavior, anxiety, and depression. The only variable to mediate the DS-CBT effect on the SF-12v2 PCS score was avoidance behavior. CONCLUSIONS Our findings largely confirmed the logic model underlying the development of CBT for patients with DS. Interventions could be additionally developed to specifically address beliefs about emotions to assess whether it improves outcomes.

Abstract
INTRODUCTION This study aimed to provide a preliminary assessment of objective and subjective neurocognitive functioning in individuals with functional motor symptoms (FMS) and/or functional seizures (FS). We tested the hypotheses that the FMS/FS group would display poorer objective attentional and executive functioning, altered social cognition, and reduced metacognitive accuracy. METHOD Individuals with FMS/FS (n = 16) and healthy controls (HCs, n = 17) completed an abbreviated CANTAB battery, and measures of intellectual functioning, subjective cognitive complaints, performance validity, and comorbid symptoms. Subjective performance ratings were obtained to assess local metacognitive accuracy. RESULTS The groups were comparable in age (p = 0.45), sex (p = 0.62), IQ (p = 0.57), and performance validity (p-values = 0.10-0.91). We observed no impairment on any CANTAB test in this FMS/FS sample compared to HCs, although the FMS/FS group displayed shorter reaction times on the Emotional Bias task (anger) (p = 0.01, np2 = 0.20). The groups did not differ in subjective performance ratings (p-values 0.15). Whilst CANTAB attentional set-shifting performance (total trials/errors) correlated with subjective performance ratings in HCs (p-values<0.005, rs = -0.85), these correlations were non-significant in the FMS/FS sample (p-values = 0.10-0.13, rs-values = -0.46-0.50). The FMS/FS group reported more daily cognitive complaints than HCs (p = 0.006, g = 0.92), which were associated with subjective performance ratings on CANTAB sustained attention (p = 0.001, rs = -0.74) and working memory tests (p < 0.001, rs = -0.75), and with depression (p = 0.003, rs = 0.70), and somatoform (p = 0.003, rs = 0.70) and psychological dissociation (p-values<0.005, rs-values = 0.67-0.85). CONCLUSIONS These results suggest a discordance between objective and subjective neurocognitive functioning in this FMS/FS sample, reflecting intact test performance alongside poorer subjective cognitive functioning. Further investigation of neurocognitive functioning in FND subgroups is necessary.

Abstract
Functional neurological disorder (FND) is a common and disabling disorder, often misunderstood by clinicians. Although viewed sceptically by some, FND is a diagnosis that can be made accurately, based on positive clinical signs, with clinical features that have remained stable for over 100 years. Despite some progress in the last decade, people with FND continue to suffer subtle and overt forms of discrimination by clinicians, researchers and the public. There is abundant evidence that disorders perceived as primarily affecting women are neglected in healthcare and medical research, and the course of FND mirrors this neglect. We outline the reasons why FND is a feminist issue, incorporating historical and contemporary clinical, research and social perspectives. We call for parity for FND in medical education, research and clinical service development so that people affected by FND can receive the care they need.

Abstract
Altered interoception may be a pathophysiological mechanism in functional neurological disorder (FND). However, findings have been inconsistent across interoceptive dimensions in FND including functional motor symptoms (FMS) and seizures (FS). Here, individuals with FMS/FS (n = 17) and healthy controls (HC, n = 17) completed measures of interoceptive accuracy and insight (adapted heartbeat tracking task [HTT] with confidence ratings), a time estimation control task (TET) and the Multidimensional Assessment of Interoceptive Awareness-2 (MAIA-2) to assess interoceptive sensibility. The groups did not differ in interoceptive accuracy (p = 1.00, g = 0.00) or confidence (p = .99, g = 0.004), although the FMS/FS group displayed lower scores on the "Not-Distracting" (p < .001, g = 1.42) and "Trusting" (p = .005, g = 1.17) MAIA-2 subscales, relative to HCs. The groups did not differ in TET performance (p = .82, g = 0.08). There was a positive relationship between HTT accuracy and confidence (insight) in HCs (r = .61, p = .016) but not in FMS/FS (r = 0.11, p = .69). HTT confidence was positively correlated with MAIA-2 "Self-Regulation" (r = 0.77, p = .002) and negatively correlated with FND symptom severity (r = -0.84, p < .001) and impact (r = -0.86, p < .001) in FMS/FS. Impaired interoceptive accuracy may not be a core feature in FMS/FS, but reduced insight and altered sensibility may be relevant. Reduced certainty in self-evaluations of bodily experiences may contribute to the pathogenesis of FND symptoms.

Abstract
BACKGROUND Motor neuron disease (MND) is a fatal, progressive neurodegenerative disease that causes progressive weakening and wasting of limb, bulbar, thoracic and abdominal muscles. Clear evidence-based guidance on how psychological distress should be managed in people living with MND (plwMND) is lacking. Acceptance and Commitment Therapy (ACT) is a form of psychological therapy that may be particularly suitable for this population. However, to the authors' knowledge, no study to date has evaluated ACT for plwMND. Consequently, the primary aim of this uncontrolled feasibility study was to examine the feasibility and acceptability of ACT for improving the psychological health of plwMND. METHODS PlwMND aged ≥ 18 years were recruited from 10 UK MND Care Centres/Clinics. Participants received up to 8 one-to-one ACT sessions, developed specifically for plwMND, plus usual care. Co-primary feasibility and acceptability outcomes were uptake (≥ 80% of the target sample [N = 28] recruited) and initial engagement with the intervention (≥ 70% completing ≥ 2 sessions). Secondary outcomes included measures of quality of life, anxiety, depression, disease-related functioning, health status and psychological flexibility in plwMND and quality of life and burden in caregivers. Outcomes were assessed at baseline and 6 months. RESULTS Both a priori indicators of success were met: 29 plwMND (104%) were recruited and 76% (22/29) attended ≥ 2 sessions. Attrition at 6-months was higher than anticipated (8/29, 28%), but only two dropouts were due to lack of acceptability of the intervention. Acceptability was further supported by good satisfaction with therapy and session attendance. Data were possibly suggestive of small improvements in anxiety and psychological quality of life from baseline to 6 months in plwMND, despite a small but expected deterioration in disease-related functioning and health status. CONCLUSIONS There was good evidence of acceptability and feasibility. Limitations included the lack of a control group and small sample size, which complicate interpretation of findings. A fully powered RCT to evaluate the clinical and cost-effectiveness of ACT for plwMND is underway. TRIAL REGISTRATION The study was pre-registered with the ISRCTN Registry (ISRCTN12655391).

Abstract
PURPOSE Little is known about the accuracy of the GAD-7, a self-report anxiety measure, in detecting generalised anxiety disorder (GAD) in people with dissociative seizures (DS). We evaluated the reliability, validity and uniformity of the GAD-7 using a diagnosis of GAD on the Mini-International Neuropsychiatric Interview as a reference. METHODS We assessed 368 adults with DS at the pre-randomisation phase of the CODES trial. Factor analysis for categorical data assessed GAD-7 uniformity. Diagnostic accuracy was assessed by estimating the area under the curve (AUC). We evaluated discriminant validity, reviewed data on convergent validity and calculated internal consistency. We explored correlations between GAD-7 scores and monthly DS frequency, frequency of severe seizures and measures of behavioural and emotional avoidance. RESULTS Internal consistency of the GAD-7 was high (α = 0.92). Factor analysis elicited one main factor and general measurement invariance. Diagnostic accuracy was fair (AUC = 0.72) but the best balance of sensitivity and specificity occurred at a cut-off of ≥12 and still had a specificity rate of only 68%. Discriminant and convergent validity were good. GAD-7 scores correlated positively with DS frequency, severe seizure frequency, behavioural and emotional avoidance (all p < 0.001). CONCLUSION Findings regarding internal consistency and factor structure parallel previous psychometric evaluations of the GAD-7. Correlations between GAD-7 scores and DS occurrence/severity and avoidance are evidence of the concept validity of GAD-7 and provide further support for a fear-avoidance treatment model for DS. However, the utility of the GAD-7 as a diagnostic instrument for generalised anxiety disorder is limited in patients with DS.

Abstract
Objectives/AimsDissociation is a potential mechanism in FND. Although scientific studies report elevated rates of dissociative symptoms in FND, a systematic assessment of the biological and clinical correlates of dissociation in FND is lacking. We aimed to systematically review the current evidence describing dissociative symptoms and disorders in functional neurological disorder (FND), and additionally conduct a meta-analysis of dissociative symptom severity in FND. We also aimed to synthesise the existing data on biological and clinical correlates of dissociation in FND.MethodsWe systematically searched Embase, PsycINFO, and Medline, combining terms for FND and dissociation. Studies were eligible for inclusion if reporting on dissociative symptom scale scores or rates of dissociative disorder in FND samples. Studies were appraised for methodological quality using modified Newcastle-Ottawa criteria. Findings pertaining to dissociative symptoms or disorders, as well as biological and clinical correlates of dissociation in FND samples, were synthesised qualitatively. Dissociative symptom scores were included in a meta-analysis using random and mixed effects models.ResultsTwo-thousand and eighty-eight records were screened and seventy-nine studies were included in the final review. Dissociative symptoms were elevated in FND. The meta-analysis demonstrated a significant elevation in dissociation in FND samples relative to neurological and healthy controls, but not psychiatric controls. Dissociative disorders were frequently co-morbid in FND samples. Psychoform (cognitive) dissociation was more prominent in FND-seizures, whereas somatoform (physical) dissociation tended to be more prominent in FND-motor symptom samples. Dissociation was associated with FND symptom severity or frequency, general psychopathology, and reduced quality of life. Biological correlates of elevated dissociation included structural and functional brain alterations in regions that have previously been implicated in FND, such as the anterior cingulate cortex.ConclusionsDissociative symptoms and disorders are common in FND, and different FND subgroups appear to endorse varying degrees of psychoform or somatoform dissociation. Presence of dissociative symptoms in FND is associated with adverse clinical features; there is therefore a clinical need to assess patients with FND for dissociative symptomatology and to address these symptoms during treatment. Future research should examine dissociation further in different FND subgroups, using measures that distinguish between different types of dissociation, alongside measures of underlying pathophysiology.

Abstract
BACKGROUND Studies have reported elevated rates of dissociative symptoms and comorbid dissociative disorders in functional neurological disorder (FND); however, a comprehensive review is lacking. AIMS To systematically review the severity of dissociative symptoms and prevalence of comorbid dissociative disorders in FND and summarise their biological and clinical associations. METHOD We searched Embase, PsycInfo and MEDLINE up to June 2021, combining terms for FND and dissociation. Studies were eligible if reporting dissociative symptom scores or rates of comorbid dissociative disorder in FND samples. Risk of bias was appraised using modified Newcastle-Ottawa criteria. The findings were synthesised qualitatively and dissociative symptom scores were included in a meta-analysis (PROSPERO CRD42020173263). RESULTS Seventy-five studies were eligible (FND n = 3940; control n = 3073), most commonly prospective case-control studies (k = 54). Dissociative disorders were frequently comorbid in FND. Psychoform dissociation was elevated in FND compared with healthy (g = 0.90, 95% CI 0.66-1.14, I2 = 70%) and neurological controls (g = 0.56, 95% CI 0.19-0.92, I2 = 67%). Greater psychoform dissociation was observed in FND samples with seizure symptoms versus healthy controls (g = 0.94, 95% CI 0.65-1.22, I2 = 42%) and FND samples with motor symptoms (g = 0.40, 95% CI -0.18 to 1.00, I2 = 54%). Somatoform dissociation was elevated in FND versus healthy controls (g = 1.80, 95% CI 1.25-2.34, I2 = 75%). Dissociation in FND was associated with more severe functional symptoms, worse quality of life and brain alterations. CONCLUSIONS Our findings highlight the potential clinical utility of assessing patients with FND for dissociative symptomatology. However, fewer studies investigated FND samples with motor symptoms and heterogeneity between studies and risk of bias were high. Rigorous investigation of the prevalence, features and mechanistic relevance of dissociation in FND is needed.

Abstract
BACKGROUND Motor neuron disease (MND) is a rapidly progressive, fatal neurodegenerative disease that predominantly affects motor neurons from the motor cortex to the spinal cord and causes progressive wasting and weakening of bulbar, limb, abdominal and thoracic muscles. Prognosis is poor and median survival is 2-3 years following symptom onset. Psychological distress is relatively common in people living with MND. However, formal psychotherapy is not routinely part of standard care within MND Care Centres/clinics in the UK, and clear evidence-based guidance on improving the psychological health of people living with MND is lacking. Previous research suggests that Acceptance and Commitment Therapy (ACT) may be particularly suitable for people living with MND and may help improve their psychological health. AIMS To assess the clinical and cost-effectiveness of ACT modified for MND plus usual multidisciplinary care (UC) in comparison to UC alone for improving psychological health in people living with MND. METHODS The COMMEND trial is a multi-centre, assessor-blind, parallel, two-arm RCT with a 10-month internal pilot phase. 188 individuals aged ≥ 18 years with a diagnosis of definite, laboratory-supported probable, clinically probable, or possible familial or sporadic amyotrophic lateral sclerosis, and additionally the progressive muscular atrophy and primary lateral sclerosis variants, will be recruited from approximately 14 UK-based MND Care Centres/clinics and via self-referral. Participants will be randomly allocated to receive up to eight 1:1 sessions of ACT plus UC or UC alone by an online randomisation system. Participants will complete outcome measures at baseline and at 6- and 9-months post-randomisation. The primary outcome will be quality of life at six months. Secondary outcomes will include depression, anxiety, psychological flexibility, health-related quality of life, adverse events, ALS functioning, survival at nine months, satisfaction with therapy, resource use and quality-adjusted life years. Primary analyses will be by intention to treat and data will be analysed using multi-level modelling. DISCUSSION This trial will provide definitive evidence on the clinical and cost-effectiveness of ACT plus UC in comparison to UC alone for improving psychological health in people living with MND.

Abstract
OBJECTIVE We explored moderators of cognitive behavioural therapy (CBT) treatment effects and predictors of outcome at 12-month follow-up in the CODES Trial (N = 368) comparing CBT plus standardised medical care (SMC) vs SMC-alone for dissociative seizures (DS). METHODS We undertook moderator analyses of baseline characteristics to determine who had benefited from being offered CBT 12 months post-randomisation. Outcomes included: monthly DS frequency, psychosocial functioning (Work and Social Adjustment Scale - WSAS), and health-related quality of life (Mental Component Summary (MCS) and Physical Component Summary (PCS) SF-12v2 scores). When moderating effects were absent, we tested whether baseline variables predicted change irrespective of treatment allocation. RESULTS Moderator analyses revealed greater benefits (p < 0.05) of CBT on DS frequency for participants with more (≥22) symptoms (Modified PHQ-15) or ≥ 1 current (M.I.N.I.-confirmed) comorbid psychiatric diagnosis at baseline. The effect of CBT on PCS scores was moderated by gender; women did better than men in the CBT + SMC group. Predictors of improved outcome included: not receiving disability benefits, lower anxiety and/or depression scores (PCS, MCS, WSAS); shorter duration, younger age at DS onset, employment, fewer symptoms and higher educational qualification (PCS, WSAS); stronger belief in the diagnosis and in CBT as a "logical" treatment (MCS). Some variables that clinically might be expected to moderate/predict outcome (e.g., maladaptive personality traits, confidence in treatment) were not shown to be relevant. CONCLUSION Patient complexity interacted with treatment. CBT was more likely to reduce DS frequency in those with greater comorbidity. Other patient characteristics predicted outcome regardless of the received intervention.

Abstract
Evidence-based guidelines use systematic reviews to support clinical recommendations. Adherence to evidence-based guidelines improves healthcare costs and patient outcomes. Recent randomized trials make guidelines for functional neurological disorders possible.
Evidence-based clinical practice guidelines, based on systematic reviews of existing evidence, play an important role in improving and standardizing the quality of patient care in many medical and psychiatric disorders, and could play an important role in the diagnosis and treatment of functional seizures and other functional neurological disorder (FND) subtypes. There are several reasons to think that evidence-based guidelines might be especially beneficial for the management of FND. In particular, the interdisciplinary and multidisciplinary teamwork necessary for the care of people with FND, the current lack of formal clinical training in FND, and the rapidly expanding body of evidence relating to FND all make guidelines based on systematic literature reviews especially valuable. In this perspective piece, we review clinical practice guidelines, their advantages and limitations, the reasons why evidence-based guidelines might be especially beneficial in the diagnosis and treatment of FND, and the steps that must be taken to create such guidelines for FND. We propose that professional organizations such as the American Academy of Neurology and the American Psychiatric Association undertake guideline development, ideally to create a co-authored or jointly endorsed set of guidelines that can set standards for interdisciplinary care for neurologists and mental health clinicians alike.

Abstract
Amongst the most important conditions in the differential diagnosis of epilepsy is the one that manifests as paroxysms of altered behaviour, awareness, sensation or sense of bodily control in ways that often resemble epileptic seizures, but without the abnormal excessive or synchronous electrical activity in the brain that defines these. Despite this importance, there remains little agreement - and frequent debate - on what to call this condition, known inter alia as psychogenic non-epileptic seizures (PNES), dissociative seizures (DS), functional seizures (FS), non-epileptic attack disorder (NEAD), pseudoseizures, conversion disorder with seizures, and by many other labels besides. This choice of terminology is not merely academic - it affects patients' response to and understanding of their diagnosis, and their ability to navigate health care systems.This paper summarises two recent discussions hosted by the American Epilepsy Society and Functional Neurological Disorders Society on the naming of this condition. These discussions are conceptualised as the initial step of an exploration of whether it might be possible to build consensus for a new diagnostic label.

Abstract
BACKGROUND We examined demographic, clinical, and psychological characteristics of a large cohort (n = 368) of adults with dissociative seizures (DS) recruited to the CODES randomised controlled trial (RCT) and explored differences associated with age at onset of DS, gender, and DS semiology. METHODS Prior to randomisation within the CODES RCT, we collected demographic and clinical data on 368 participants. We assessed psychiatric comorbidity using the Mini-International Neuropsychiatric Interview (M.I.N.I.) and a screening measure of personality disorder and measured anxiety, depression, psychological distress, somatic symptom burden, emotional expression, functional impact of DS, avoidance behaviour, and quality of life. We undertook comparisons based on reported age at DS onset (<40 v. ⩾40), gender (male v. female), and DS semiology (predominantly hyperkinetic v. hypokinetic). RESULTS Our cohort was predominantly female (72%) and characterised by high levels of socio-economic deprivation. Two-thirds had predominantly hyperkinetic DS. Of the total, 69% had ⩾1 comorbid M.I.N.I. diagnosis (median number = 2), with agoraphobia being the most common concurrent diagnosis. Clinical levels of distress were reported by 86% and characteristics associated with maladaptive personality traits by 60%. Moderate-to-severe functional impairment, high levels of somatic symptoms, and impaired quality of life were also reported. Women had a younger age at DS onset than men. CONCLUSIONS Our study highlights the burden of psychopathology and socio-economic deprivation in a large, heterogeneous cohort of patients with DS. The lack of clear differences based on gender, DS semiology and age at onset suggests these factors do not add substantially to the heterogeneity of the cohort.

Abstract
Objectives/AimsAmyotrophic Lateral Sclerosis (ALS), also known as Motor Neuron Disease (MND), is a progressive and life-limiting neurodegenerative disease which can involve behavioural change. There are five commonly reported disease-specific screening tools of behavioural change but it is not clear how they differ in applicability. This study therefore set out to investigate the extent to which these measures similarly identify impairment by examining i) intercorrelations between scores on the measures completed about the same people with ALS, and ii) the percentage of people with ALS characterised as impaired on each measure.MethodsThe behavioural component of the ALS-Cognitive Behavioural Screen (ALS-CBS-b), behavioural component of the Edinburgh Cognitive and Behavioural ALS Screen (ECAS-b), ALS-Frontotemporal Dementia Questionnaire (ALS-FTD-Q), Beaumont Behavioural Inventory (BBI), and MND Behavioural Instrument (MiND-B) were all completed by 35 carers of people with ALS. Total scores for each measure underwent Spearman correlation analysis. Classifications of impairment (for behavioural impairment or ALS-FTD) were determined using published cut-offs and agreement between measures was determined by calculating Cohens kappa coefficients.ResultsThe behavioural measures were significantly intercorrelated (p<0.05 in all cases) but with differing strengths of association. The association between the ALS-CBS-b and ALS-FTD-Q was weak to moderate (r=0.41) while other associations between the ALS-FTD-Q, MiND-B, BBI, and ALS-CBS-b were moderate to strong (0.53-0.75). While the ECAS-b was moderately associated with the BBI (r=0.53), the ECAS-b was only weakly to moderately associated with the ALS-CBS-b, MiND-B and ALS-FTD-Q (0.36-0.48). The association between ALS-CBS-b and ALS-FTD-Q scores (r=0.41) was similarly in the weak to moderate range. The ECAS-b and ALS-CBS-b had the weakest intercorrelation (r=0.36). Percentages of the sample classified with behavioural involvement by the measures ranged between 20.0% (ALS-FTD-Q) and 74.3% (MiND-B). Percentages of the sample classified with ALS-FTD by the measures ranged between 2.9% (ECAS-b) and 20% (ALS-CBS-b). Agreement of classification between measures (Cohens kappa) was mostly fair to moderate (0.21-0.57) although generally better for classifications of ALS-FTD than for milder behavioural involvement. Between the ECAS-b and BBI there was complete agreement on the classification of ALS-FTD (k = 1.0).ConclusionsExisting measures of behavioural change in people with ALS may yield very differing conclusions and cannot be assumed to be interchangeable. Variability in the detection of impairment between measures may result from differing item content, behaviours sampled or cut-off scores for impairment. This inconsistency between measures may lead to inappropriate healthcare provision and discrepancies in research conclusions.FundingMND Association

Abstract
BACKGROUND The PHQ-9 is a self-administered depression screening instrument. Little is known about its utility and accuracy in detecting depression in adults with dissociative seizures (DS). OBJECTIVES Using the Mini - International Neuropsychiatric Interview as a reference, we evaluated the diagnostic accuracy of the PHQ-9 in adults with DS, and examined its convergent and discriminant validity and uniformity. METHODS Our sample comprised 368 people with DS who completed the pre-randomisation assessment of the CODES trial. The uniformity of the PHQ-9 was determined using factor analysis for categorical data. Optimal cut-offs were determined using the area under the curve (AUC), Youden Index, and diagnostic odds ratio (DOR). Convergent and discriminant validity were assessed against pre-randomisation measures. RESULTS Internal consistency of the PHQ-9 was high (α = 0.87). While the diagnostic odds ratio suggested that a cut-off of ≥10 had the best predictive performance (DOR = 14.7), specificity at this cut off was only 0.49. AUC (0.74) and Youden Index (0.48) suggested a ≥ 13 cut-off would yield an optimal sensitivity (0.81) and specificity (0.67) balance. However, a cut-off score of ≥20 would be required to match specificity resulting from a cut-off of ≥13 in other medical conditions. We found good convergent and discriminant validity and one main factor for the PHQ-9. CONCLUSIONS In terms of internal consistency and structure, our findings were consistent with previous validation studies but indicated that a higher cut-off would be required to identify DS patients with depression with similar specificity achieved with PHQ-9 screening in different clinical and non-clinical populations.

Abstract
BACKGROUND Dissociative (non-epileptic) seizures are potentially treatable by psychotherapeutic interventions; however, the evidence for this is limited. OBJECTIVES To evaluate the clinical effectiveness and cost-effectiveness of dissociative seizure-specific cognitive-behavioural therapy for adults with dissociative seizures. DESIGN This was a pragmatic, multicentre, parallel-arm, mixed-methods randomised controlled trial. SETTING This took place in 27 UK-based neurology/epilepsy services, 17 liaison psychiatry/neuropsychiatry services and 18 cognitive-behavioural therapy services. PARTICIPANTS Adults with dissociative seizures in the previous 8 weeks and no epileptic seizures in the previous year and meeting other eligibility criteria were recruited to a screening phase from neurology/epilepsy services between October 2014 and February 2017. After psychiatric assessment around 3 months later, eligible and interested participants were randomised between January 2015 and May 2017. INTERVENTIONS Standardised medical care consisted of input from neurologists and psychiatrists who were given guidance regarding diagnosis delivery and management; they provided patients with information booklets. The intervention consisted of 12 dissociative seizure-specific cognitive-behavioural therapy 1-hour sessions (plus one booster session) that were delivered by trained therapists, in addition to standardised medical care. MAIN OUTCOME MEASURES The primary outcome was monthly seizure frequency at 12 months post randomisation. The secondary outcomes were aspects of seizure occurrence, quality of life, mood, anxiety, distress, symptoms, psychosocial functioning, clinical global change, satisfaction with treatment, quality-adjusted life-years, costs and cost-effectiveness. RESULTS In total, 698 patients were screened and 368 were randomised (standardised medical care alone, n = 182; and cognitive-behavioural therapy plus standardised medical care, n = 186). Primary outcome data were obtained for 85% of participants. An intention-to-treat analysis with multivariate imputation by chained equations revealed no significant between-group difference in dissociative seizure frequency at 12 months [standardised medical care: median of seven dissociative seizures (interquartile range 1-35 dissociative seizures); cognitive-behavioural therapy and standardised medical care: median of four dissociative seizures (interquartile range 0-20 dissociative seizures); incidence rate ratio 0.78, 95% confidence interval 0.56 to 1.09; p = 0.144]. Of the 16 secondary outcomes analysed, nine were significantly better in the arm receiving cognitive-behavioural therapy at a p-value < 0.05, including the following at a p-value ≤ 0.001: the longest dissociative seizure-free period in months 7-12 inclusive post randomisation (incidence rate ratio 1.64, 95% confidence interval 1.22 to 2.20; p = 0.001); better psychosocial functioning (Work and Social Adjustment Scale, standardised treatment effect -0.39, 95% confidence interval -0.61 to -0.18; p < 0.001); greater self-rated and clinician-rated clinical improvement (self-rated: standardised treatment effect 0.39, 95% confidence interval 0.16 to 0.62; p = 0.001; clinician rated: standardised treatment effect 0.37, 95% confidence interval 0.17 to 0.57; p < 0.001); and satisfaction with treatment (standardised treatment effect 0.50, 95% confidence interval 0.27 to 0.73; p < 0.001). Rates of adverse events were similar across arms. Cognitive-behavioural therapy plus standardised medical care produced 0.0152 more quality-adjusted life-years (95% confidence interval -0.0106 to 0.0392 quality-adjusted life-years) than standardised medical care alone. The incremental cost-effectiveness ratio (cost per quality-adjusted life-year) for cognitive-behavioural therapy plus standardised medical care versus standardised medical care alone based on the EuroQol-5 Dimensions, five-level version, and imputed data was £120,658. In sensitivity analyses, incremental cost-effectiveness ratios ranged between £85,724 and £206,067. Qualitative and quantitative process evaluations highlighted useful study components, the importance of clinical experience in treating patients with dissociative seizures and potential benefits of our multidisciplinary care pathway. LIMITATIONS Unlike outcome assessors, participants and clinicians were not blinded to the interventions. CONCLUSIONS There was no significant additional benefit of dissociative seizure-specific cognitive-behavioural therapy in reducing dissociative seizure frequency, and cost-effectiveness over standardised medical care was low. However, this large, adequately powered, multicentre randomised controlled trial highlights benefits of adjunctive dissociative seizure-specific cognitive-behavioural therapy for several clinical outcomes, with no evidence of greater harm from dissociative seizure-specific cognitive-behavioural therapy.

Abstract
Objectives The Psychology Task Force of the Medical Therapies Commission of the International League Against Epilepsy (ILAE) has been charged with taking steps to improve global mental health care for people with epilepsy. This study aimed to inform the direction and priorities of the Task Force by examining epilepsy healthcare providers' current practical experiences, barriers, and unmet needs around addressing depression and anxiety in their patients. Methods A voluntary 27-item online survey was distributed via ILAE chapters and networks. It assessed practices in the areas of screening, referral, management, and psychological care for depression and anxiety. A total of 445 participants, from 67 countries (68% high income), commenced the survey, with 87% completing all components. Most respondents (80%) were either neurologists or epileptologists. Results Less than half of respondents felt adequately resourced to manage depression and anxiety. There was a lack of consensus about which health professionals were responsible for screening and management of these comorbidities. About a third only assessed for depression and anxiety following spontaneous report and lack of time was a common barrier (>50%). Routine referrals to psychiatrists (>55%) and psychologists (>41%) were common, but approximately one third relied on watchful waiting. A lack of both trained mental health specialists (>55%) and standardized procedures (>38%) was common barriers to referral practices. The majority (>75%) of respondents' patients identified with depression or anxiety had previously accessed psychotropic medications or psychological treatments. However, multiple barriers to psychological treatments were endorsed, including accessibility difficulties (52%). Significance The findings suggest that while the importance of managing depression and anxiety in patients with epilepsy is being recognized, there are ongoing barriers to effective mental health care. Key future directions include the need for updated protocols in this area and the integration of mental health professionals within epilepsy settings.

Abstract
The development and selection of optimal outcome measures is increasingly recognized as a key component of evidence-based medicine, particularly the need for the development of a standardized set of measures for use in clinical trials. This process is particularly complex for functional neurological disorder (FND) for several reasons. FND can present with a wide range of symptoms that resemble the full spectrum of other neurological disorders. Additional physical (e.g., pain, fatigue) and psychological (e.g., depression, anxiety) symptoms are commonly associated with FND, which also can be highly disabling with implications for prognosis, and warrant concurrent assessment, despite an unclear etiological relationship with FND. Furthermore, several unique clinical aspects of FND make it likely that the usual prioritization of "objective" (or clinician-rated) over "subjective" (or patient-rated) measures might not be appropriate. Self-report measures may be more clinically meaningful in this patient population. Despite being a common and disabling disorder, there has been little research into outcome measures in FND, and to date trials have largely used measures designed for the assessment of other disorders. An international FND Core Outcome Measure group (FND-COM) has been established to develop a consensus battery of outcomes for FND: a "core outcome set." In this perspective article, the authors reviewed the process of outcome measure development and selection before considering the specific features of FND affecting the development of a core outcome set, as well as a research agenda to optimize outcome measurement in this complex neuropsychiatric disorder.

Abstract
BACKGROUND Nested within a large, multicenter randomized controlled trial (RCT) for people with dissociative seizures (DS), the study used purposive sampling to explore participants' experience of participating in an RCT, their experience of DS-specific cognitive behavioral therapy (CBT) and another component of the RCT, Standardized Medical Care (SMC) and their perceptions of and reflections on seizure management and change. METHODS A qualitative study using semistructured interviews was conducted with 30 participants in an RCT (the COgnitive behavioral therapy vs standardized medical care for adults with Dissociative non-Epileptic Seizures (CODES) Trial) investigating the effectiveness of two treatments for DS. Key themes and subthemes were identified using thematic framework analysis (TFA). RESULTS Analysis yielded three overarching themes: taking part in a treatment trial - "the only thing out there", the experience of treatment techniques that were perceived to help with seizure management, and reflections on an "unpredictable recovery". CONCLUSIONS People with DS are amenable to participating in a psychotherapy RCT and described a largely positive experience. They also described the applicability of aspects of DS-specific CBT and SMC in the management of their DS, received within the confines of the CODES trial. Factors that appeared to account for the variability in response to treatment delivery included individual preferences for the nature of sessions, the nature of therapeutic relationships, readiness to discuss trauma, other aspects of emotional avoidance, and whether therapy provided something new.

Abstract
BACKGROUND Given the significant impact epilepsy may have on the health-related quality of life (HRQOL) of individuals with epilepsy and their families, there is increasing clinical interest in evidence-based psychological treatments, aimed at enhancing psychological and seizure-related outcomes for this group. This is an updated version of the original Cochrane Review published in Issue 10, 2017. OBJECTIVES To assess the impact of psychological treatments for people with epilepsy on HRQOL outcomes. SEARCH METHODS For this update, we searched the following databases on 12 August 2019, without language restrictions: Cochrane Register of Studies (CRS Web), which includes randomized or quasi-randomized controlled trials from the Specialized Registers of Cochrane Review Groups including Epilepsy, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid, 1946 to 09 August 2019), and PsycINFO (EBSCOhost, 1887 onwards), and from PubMed, Embase, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform (ICTRP). We screened the references from included studies and relevant reviews, and contacted researchers in the field for unpublished studies. SELECTION CRITERIA We considered randomized controlled trials (RCTs) and quasi-RCTs for this review. HRQOL was the main outcome. For the operational definition of 'psychological treatments', we included a broad range of skills-based psychological treatments and education-only interventions designed to improve HRQOL, seizure frequency and severity, as well as psychiatric and behavioral health comorbidities for adults and children with epilepsy. These psychological treatments were compared to treatment as usual (TAU), an active control group (such as social support group), or antidepressant pharmacotherapy. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS We included 36 completed RCTs, with a total of 3526 participants. Of these studies, 27 investigated skills-based psychological interventions. The remaining nine studies were education-only interventions. Six studies investigated interventions for children and adolescents, three studies investigated interventions for adolescents and adults, and the remaining studies investigated interventions for adults. Based on satisfactory clinical and methodological homogeneity, we pooled data from 11 studies (643 participants) that used the Quality of Life in Epilepsy-31 (QOLIE-31) or other QOLIE inventories (such as QOLIE-89 or QOLIE-31-P) convertible to QOLIE-31. We found significant mean changes for the QOLIE-31 total score and six subscales (emotional well-being, energy and fatigue, overall QoL, seizure worry, medication effects, and cognitive functioning). The mean changes in the QOLIE-31 total score (mean improvement of 5.23 points, 95% CI 3.02 to 7.44; P < 0.001), and the overall QoL score (mean improvement of 5.95 points, 95% CI 3.05 to 8.85; P < 0.001) exceeded the threshold of minimally important change (MIC: total score: 4.73 points; QoL score: 5.22 points), indicating a clinically meaningful postintervention improvement in HRQOL. We downgraded the certainty of the evidence provided by the meta-analysis due to serious risks of bias in some of the included studies. Consequently, these results provided moderate-certainty evidence that psychological treatments for adults with epilepsy may enhance overall HRQOL. AUTHORS' CONCLUSIONS Implications for practice: Skills-based psychological interventions improve HRQOL in adults and adolescents with epilepsy. Adjunctive use of skills-based psychological treatments for adults and adolescents with epilepsy may provide additional benefits in HRQOL when these are incorporated into patient-centered management. We judge the evidence to be of moderate certainty. IMPLICATIONS FOR RESEARCH Investigators should strictly adhere to the CONSORT guidelines to improve the quality of reporting on their interventions. A thorough description of intervention protocols is necessary to ensure reproducibility. When examining the effectiveness of psychological treatments for people with epilepsy, the use of standardized HRQOL inventories, such as the Quality of Life in Epilepsy Inventories (QOLIE-31, QOLIE-31-P, and QOLIE-89) would increase comparability. Unfortunately, there is a critical gap in pediatric RCTs and RCTs including people with epilepsy and intellectual disabilities. Finally, in order to increase the overall quality of RCT study designs, adequate randomization with allocation concealment and blinded outcome assessment should be pursued. As attrition is often high in research that requires active participation, an intention-to-treat analysis should be carried out. Treatment fidelity and treatment competence should also be assessed. These important dimensions, which are related to 'Risk of bias' assessment, should always be reported.

Abstract
Introduction: We aimed to examine susceptibility to dissociation and the impact of dissociation on interoceptive processing in individuals with functional neurological disorder (FND). We hypothesised that dissociative states would be elevated and interoceptive accuracy and awareness impaired at baseline in people with FND, and that such differences would be exacerbated following acute dissociation. Methods: Nineteen adults with FND were compared to 20 healthy controls. A modified heart-beat tracking task measured interoceptive accuracy and awareness (confidence) before and after a validated dissociation induction procedure. An exteroceptive processing control task was included. Mann-Whitney tests and r-values (effect size) were computed for between-group comparisons. Results: The FND group displayed elevated dissociation at baseline (p = 0.001, r = 0.528) compared to controls which increased following dissociation-induction (p < 0.001, r = 0.663). Interoceptive accuracy did not differ between groups at baseline (p = 0.967, r = 0.009); however, the FND group had lower accuracy scores post-induction (p = 0.021, r = 0.379). A negative correlation (trend) between change scores for dissociation and interoceptive accuracy was noted (rs = -0.411, p = 0.057). Confidence ratings on interoceptive and exteroceptive processing tasks were lower in the FND group (p-values < 0.05 or <0.01, r-values 0.331-0.489). Conclusions: Individuals with FND experienced greater susceptibility to dissociation, metacognitive deficits and impaired interoceptive accuracy than controls after acute dissociation.

Abstract
OBJECTIVES We aimed to identify existing outcome measures for functional neurological disorder (FND), to inform the development of recommendations and to guide future research on FND outcomes. METHODS A systematic review was conducted to identify existing FND-specific outcome measures and the most common measurement domains and measures in previous treatment studies. Searches of Embase, MEDLINE and PsycINFO were conducted between January 1965 and June 2019. The findings were discussed during two international meetings of the FND-Core Outcome Measures group. RESULTS Five FND-specific measures were identified-three clinician-rated and two patient-rated-but their measurement properties have not been rigorously evaluated. No single measure was identified for use across the range of FND symptoms in adults. Across randomised controlled trials (k=40) and observational treatment studies (k=40), outcome measures most often assessed core FND symptom change. Other domains measured commonly were additional physical and psychological symptoms, life impact (ie, quality of life, disability and general functioning) and health economics/cost-utility (eg, healthcare resource use and quality-adjusted life years). CONCLUSIONS There are few well-validated FND-specific outcome measures. Thus, at present, we recommend that existing outcome measures, known to be reliable, valid and responsive in FND or closely related populations, are used to capture key outcome domains. Increased consistency in outcome measurement will facilitate comparison of treatment effects across FND symptom types and treatment modalities. Future work needs to more rigorously validate outcome measures used in this population.

Abstract
OBJECTIVE To characterize disease evolution in amyotrophic lateral sclerosis using an event-based model designed to extract temporal information from cross-sectional data. Conventional methods for understanding mechanisms of rapidly progressive neurodegenerative disorders are limited by the subjectivity inherent in the selection of a limited range of measurements, and the need to acquire longitudinal data. METHODS The event-based model characterizes a disease as a series of events, each comprising a significant change in subject state. The model was applied to data from 154 patients and 128 healthy controls selected from five independent diffusion MRI datasets acquired in four different imaging laboratories between 1999 and 2016. The biomarkers modeled were mean fractional anisotropy values of white matter tracts implicated in amyotrophic lateral sclerosis. The cerebral portion of the corticospinal tract was divided into three segments. RESULTS Application of the model to the pooled datasets revealed that the corticospinal tracts were involved before other white matter tracts. Distal corticospinal tract segments were involved earlier than more proximal (i.e., cephalad) segments. In addition, the model revealed early ordering of fractional anisotropy change in the corpus callosum and subsequently in long association fibers. INTERPRETATION These findings represent data-driven evidence for early involvement of the corticospinal tracts and body of the corpus callosum in keeping with conventional approaches to image analysis, while providing new evidence to inform directional degeneration of the corticospinal tracts. This data-driven model provides new insight into the dynamics of neuronal damage in amyotrophic lateral sclerosis.

Abstract
OBJECTIVES Little is known about the experiences of therapists delivering psychotherapy for patients with dissociative seizures (DS), a complex disorder associated with a range of comorbid psychosocial and mental health difficulties. This study set out to explore therapists' experiences of delivering DS-specific, manualized cognitive behavioral therapy (CBT) to adults with DS within the context of a randomized control trial. METHODS Interviews were conducted with 12 therapists involved in the COgnitive behavioral therapy vs standardized medical care for adults with Dissociative non-Epileptic Seizures (CODES) trial and were analyzed using thematic framework analysis (TFA). RESULTS Six main themes emerged, namely 1) aspects of the intervention that were favored, while others were not always considered applicable; 2) multiple and complex difficulties faced by patients; 3) working effectively within the protocol; 4) limitations of the protocol; 5) significance of formulation; and 6) quality of standardized medical care (SMC) and difficulties of diagnosis delivery. These addressed valued aspects of the intervention, complexities of the patient group, and experiences working within a structured treatment protocol. Family involvement and psychoeducation were highlighted as important components; the applicability of graded exposure techniques, however, was restricted by patients' apparent emotional avoidance. The structure provided by the treatment protocol was valued, but flexibility was important to individualize treatment in complex cases. A comprehensive formulation was fundamental to this. The initial diagnostic explanation provided by neurologists and psychiatrists was generally considered beneficial, with patients often perceived to enter therapy with a better understanding of their condition. CONCLUSIONS This study demonstrated that the DS-specific CBT intervention met with general approval from therapists who also highlighted some practical challenges. Because of the nature of the condition, the need for experience of working with complex patients should be considered when applying the intervention to individual cases. Setting the CBT intervention in the context of a structured care pathway involving neurology and psychiatry may facilitate the therapeutic process.

Abstract
BACKGROUND Patients with functional motor disorder (FMD) experience persistent and disabling neurological symptoms such as weakness, tremor, dystonia and disordered gait. Physiotherapy is usually considered an important part of treatment; however, sufficiently-powered controlled studies are lacking. Here we present the protocol of a randomised controlled trial (RCT) that aims to evaluate the clinical and cost effectiveness of a specialist physiotherapy programme for FMD. METHODS/DESIGN The trial is a pragmatic, multicentre, single blind parallel arm randomised controlled trial (RCT). 264 Adults with a clinically definite diagnosis of FMD will be recruited from neurology clinics and randomised to receive either the trial intervention (a specialist physiotherapy protocol) or treatment as usual control (referral to a community physiotherapy service suitable for people with neurological symptoms). Participants will be followed up at 6 and 12 months. The primary outcome is the Physical Function domain of the Short Form 36 questionnaire at 12 months. Secondary domains of measurement will include participant perception of change, mobility, health-related quality of life, health service utilisation, anxiety and depression. Health economic analysis will evaluate the cost impact of trial and control interventions from a health and social care perspective as well as societal perspective. DISCUSSION This trial will be the first adequately-powered RCT of physical-based rehabilitation for FMD. TRIAL REGISTRATION International Standard Randomised Controlled Trials Number ISRCTN56136713 .

Abstract
Objective We aimed to characterize the demographics of adults with dissociative (nonepileptic) seizures, placing emphasis on distribution of age at onset, male:female ratio, levels of deprivation, and dissociative seizure semiology. Methods We collected demographic and clinical data from 698 adults with dissociative seizures recruited to the screening phase of the CODES (Cognitive Behavioural Therapy vs Standardised Medical Care for Adults With Dissociative Non‐Epileptic Seizures) trial from 27 neurology/specialist epilepsy clinics in the UK. We described the cohort in terms of age, age at onset of dissociative seizures, duration of seizure disorder, level of socioeconomic deprivation, and other social and clinical demographic characteristics and their associations. Results In what is, to date, the largest study of adults with dissociative seizures, the overall modal age at dissociative seizure onset was 19 years; median age at onset was 28 years. Although 74% of the sample was female, importantly the male:female ratio varied with age at onset, with 77% of female but only 59% of male participants developing dissociative seizures by the age of 40 years. The frequency of self‐reported previous epilepsy was 27%; nearly half of these epilepsy diagnoses were retrospectively considered erroneous by clinicians. Patients with predominantly hyperkinetic dissociative seizures had a shorter disorder duration prior to diagnosis in this study than patients with hypokinetic seizures (P < .001); dissociative seizure type was not associated with gender. Predominantly hyperkinetic seizures were most commonly seen in patients with symptom onset in their late teens. Thirty percent of the sample reported taking antiepileptic drugs; this was more common in men. More than 50% of the sample lived in areas characterized by the highest levels of deprivation, and more than two‐thirds were unemployed. Significance Females with dissociative seizures were more common at all ages, whereas the proportion of males increased with age at onset. This disorder was associated with socioeconomic deprivation. Those with hypokinetic dissociative seizures may be at risk for delayed diagnosis and treatment.

Abstract
Importance Functional neurological disorders (FND) are common sources of disability in medicine. Patients have often been misdiagnosed, correctly diagnosed after lengthy delays, and/or subjected to poorly delivered diagnoses that prevent diagnostic understanding and lead to inappropriate treatments, iatrogenic harm, unnecessary and costly evaluations, and poor outcomes. Observations Functional Neurological Symptom Disorder/Conversion Disorder was adopted by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, replacing the term psychogenic with functional and removing the criterion of psychological stress as a prerequisite for FND. A diagnosis can now be made in an inclusionary manner by identifying neurological signs that are specific to FNDs without reliance on presence or absence of psychological stressors or suggestive historical clues. The new model highlights a wider range of past sensitizing events, such as physical trauma, medical illness, or physiological/psychophysiological events. In this model, strong ideas and expectations about these events correlate with abnormal predictions of sensory data and body-focused attention. Neurobiological abnormalities include hypoactivation of the supplementary motor area and relative disconnection with areas that select or inhibit movements and are associated with a sense of agency. Promising evidence has accumulated for the benefit of specific physical rehabilitation and psychological interventions alone or in combination, but clinical trial evidence remains limited. Conclusions and Relevance Functional neurological disorders are a neglected but potentially reversible source of disability. Further research is needed to determine the dose and duration of various interventions, the value of combination treatments and multidisciplinary therapy, and the therapeutic modality best suited for each patient.

Abstract
Background: There is a lack of knowledge about what factors may impede or facilitate engagement in psychological interventions in people with motor neuron disease (pwMND) and how such interventions can be adapted to best meet the needs of this population. Objectives: To explore the needs and preferences of pwMND with respect to psychological interventions, and how best to adapt such interventions for pwMND. Methods: A series of semi-structured interviews (n = 22) and workshops (n = 3) were conducted with pwMND (n = 15), informal caregivers of pwMND (n = 10), and MND healthcare professionals (n = 12). These explored preferences and concerns that would need to be considered when delivering a psychological intervention for pwMND. Three areas were explored: (i) perceived factors that may hinder or facilitate pwMND engaging with psychological interventions; (ii) ways in which such interventions could be adapted to meet the individual needs of pwMND; and (iii) views regarding the main psychological issues that would need to be addressed. Workshops and interviews were audio recorded and transcribed and thematic analysis was used to inductively derive themes. Findings: Data could be classified within four overarching themes: unfamiliar territory; a series of losses; variability and difficulty meeting individual needs; and informal support. Conclusions: Flexibility, tailoring interventions to the individual needs of pwMND, and encouraging autonomy are key attributes for psychological interventions with pwMND. Psychological interventions such as Acceptance and Commitment Therapy (ACT) could be acceptable for pwMND if adapted to their specific needs.

Abstract
The aim of the study was to examine the effects of acute dissociation on emotional responsivity in healthy individuals. We used a previously validated technique (mirror-gazing, Caputo, 2010) to experimentally induce acute dissociation in non-clinical participants and assessed post-induction subjective responsivity (ratings of valence and arousal) to standardized emotional images. Fifty non-clinical participants were randomised to either the dissociation induction (n = 25) or control conditions (n = 25). The dissociation manipulation effect was corroborated by a significant post-induction elevation in state dissociation in the dissociation-induction group relative to controls (p = .004). The dissociation-induction group rated negative (p = .028) and neutral (p = .025) stimuli as significantly less unpleasant than controls. There was also a non-significant trend for positive stimuli to be rated as less pleasant by the dissociation-induction group compared to controls (p = .060). These findings provide experimental evidence for the short-term alleviation (i.e., emotional numbing) of negative affect during dissociative states, which may serve as a coping mechanism for some individuals. However, this tendency of emotional numbing also reduced positive affective responses to pleasant stimuli to some extent. Further investigation of dissociative phenomena and their impact on emotional processing appears warranted.

Abstract
Functional neurological disorder (FND) is a common and highly disabling disorder, but its aetiology remains enigmatic. Conceptually, there has been reduced emphasis on the role of psychosocial stressors in recent years, with a corresponding increase in neurobiological explanations. However, a wealth of evidence supports the role of psychosocial adversities (eg, stressful life events, interpersonal difficulties) as important risk factors for FND. Therefore, there is a need to integrate psychosocial (environmental) and neurobiological factors (eg, sensorimotor and cognitive functions) in contemporary models of FND. Altered emotional processing may represent a key link between psychosocial risk factors and core features of FND. Here, we summarise and critically appraise experimental studies of emotional processing in FND using behavioural, psychophysiological and/or neuroimaging measures in conjunction with affective processing tasks. We propose that enhanced preconscious (implicit) processing of emotionally salient stimuli, associated with elevated limbic reactivity (eg, amygdala), may contribute to the initiation of basic affective/defensive responses via hypothalamic and brainstem pathways (eg, periaqueductal grey). In parallel, affect-related brain areas may simultaneously exert a disruptive influence on neurocircuits involved in voluntary motor control, awareness and emotional regulation (eg, sensorimotor, salience, central executive networks). Limbic-paralimbic disturbances in patients with FND may represent one of several neurobiological adaptations linked to early, severe and/or prolonged psychosocial adversity. This perspective integrates neurobiological and psychosocial factors in FND and proposes a research agenda, highlighting the need for replication of existing findings, multimodal sampling across emotional response domains and further examination of emotional influences on sensorimotor and cognitive functions in FND populations.

Abstract
PURPOSE We investigated neurologists' experience of participating in the large CODES trial involving around 900 adults with dissociative seizures which subsequently evaluated the effectiveness of tailored cognitive behavioural therapy (CBT) plus standardised medical care versus standardised medical care alone in 368 patients with dissociative seizures. METHOD We asked all neurologists referring patients with dissociative seizures to the CODES study to complete a 43-item online survey. This examined neurologists' (i) demographics, (ii) knowledge of dissociative seizures before and after their involvement in the CODES trial, (iii) clinical practice before, during and since their involvement, and (iv) their experience of the CODES trial. RESULTS Forty-three (51%) neurologists completed the questionnaire. Only about half of neurologists could make referrals to psychological intervention specific for dissociative seizures before and after the trial. One-third of doctors reported having changed their referral practice following their involvement. The majority (>69%) agreed that patient satisfaction with different aspects of the trial was very high, and 83.7% thought that it was easy to recruit patients for the study. Over 90% agreed they would like the treatment pathway to continue. Respondents found different elements of the trial useful, in particular, the patient factsheet booklet (98%), diagnosis communication advice (93%) and the CBT package (93%). CONCLUSIONS Neurologists participating in CODES generally found it easy to recruit patients and perceived patient satisfaction as very high. However, 46.5% of neurologists could not offer psychotherapy once the trial had finished, suggesting that problems with lack of access to psychological treatment for dissociative seizures persist.

Abstract
OBJECTIVE There is currently limited research exploring healthcare professionals' (HCPs) experiences of working with patients with dissociative seizures (DS). Existing studies do not focus on the role of psychiatrists in treating this complex condition. The objective of this study was to gain an understanding of UK-based psychiatrists' experiences of the DS patient group. Against the backdrop of a UK-wide randomised controlled trial (RCT), the focus was broadened to encompass issues arising in everyday practice with the DS patient group. DESIGN, PARTICIPANTS AND METHODS A qualitative study using semistructured interviews was undertaken with 10 psychiatrists currently working with DS patients within the context of a large RCT investigating treatments for DS. Thematic analysis was used to identify key themes and subthemes. SETTING The psychiatrists were working in Liaison or Neuropsychiatry services in England. RESULTS The key themes identified were other HCPs' attitudes to DS and the challenges of the DS patient group. There is a clear knowledge gap regarding DS for many HCPs and other clinical services can be reluctant to take referrals for this patient group. Important challenges posed by this patient group included avoidance (of difficult emotions and help), alexithymia and interpersonal difficulties. Difficulties with alexithymia meant DS patients could struggle to identify triggers for their seizures and to express their emotions. Interpersonal difficulties raised included difficulties in attachment with both HCPs and family members. CONCLUSIONS A knowledge gap for HCPs regarding DS has been identified and needs to be addressed to improve patient care. Given the complexity of the patient group and that clinicians from multiple disciplines will come into contact with DS patients, it is essential for any educational strategy to be implemented across the whole range of specialties, and to account for those already in practice as well as future trainees.

Abstract
BACKGROUND Epilepsy is a common neurological condition resulting in recurrent seizures. Research evidence in long-term conditions suggests that patients benefit from self-management education and that this may improve quality of life (QoL). Epilepsy self-management education has yet to be tested in a UK setting. OBJECTIVES To determine the effectiveness and cost-effectiveness of Self-Management education for people with poorly controlled epILEpsy [SMILE (UK)]. DESIGN A parallel pragmatic randomised controlled trial. SETTING Participants were recruited from eight hospitals in London and south-east England. PARTICIPANTS Adults aged ≥ 16 years with epilepsy and two or more epileptic seizures in the past year, who were currently being prescribed antiepileptic drugs. INTERVENTION A 2-day group self-management course alongside treatment as usual (TAU). The control group received TAU. MAIN OUTCOME MEASURES The primary outcome is QoL in people with epilepsy at 12-month follow-up using the Quality Of Life In Epilepsy 31-P (QOLIE-31-P) scale. Other outcomes were seizure control, impact of epilepsy, medication adverse effects, psychological distress, perceived stigma, self-mastery and medication adherence. Cost-effectiveness analyses and a process evaluation were undertaken. RANDOMISATION A 1 : 1 ratio between trial arms using fixed block sizes of two. BLINDING Participants were not blinded to their group allocation because of the nature of the study. Researchers involved in data collection and analysis remained blinded throughout. RESULTS The trial completed successfully. A total of 404 participants were enrolled in the study [SMILE (UK), n = 205; TAU, n = 199] with 331 completing the final follow-up at 12 months [SMILE (UK), n = 163; TAU, n = 168]. In the intervention group, 61.5% completed all sessions of the course. No adverse events were found to be related to the intervention. At baseline, participants had a mean age of 41.7 years [standard deviation (SD) 14.1 years], and had epilepsy for a median of 18 years. The mean QOLIE-31-P score for the whole group at baseline was 66.0 out of 100.0 (SD 14.2). Clinically relevant levels of anxiety symptoms were reported in 53.6% of the group and depression symptoms in 28.0%. The results following an intention-to-treat analysis showed no change in any measures at the 12-month follow-up [QOLIE-31-P: SMILE (UK) mean: 67.4, SD 13.5; TAU mean: 69.5, SD 14.8]. The cost-effectiveness study showed that SMILE (UK) was possibly cost-effective but was also associated with lower QoL. The process evaluation with 20 participants revealed that a group course increased confidence by sharing with others and improved self-management behaviours. CONCLUSIONS For people with epilepsy and persistent seizures, a 2-day self-management education course is cost-saving, but does not improve QoL after 12-months or reduce anxiety or depression symptoms. A psychological intervention may help with anxiety and depression. Interviewed participants reported attending a group course increased their confidence and helped them improve their self-management. FUTURE WORK More research is needed on self-management courses, with psychological components and integration with routine monitoring. TRIAL REGISTRATION Current Controlled Trials ISRCTN57937389.

Abstract
Gastrostomy and noninvasive ventilation (NIV) are recommended interventions for the management of symptoms associated with amyotrophic lateral sclerosis (ALS). This study aimed to quantify the views of a range of healthcare professionals (HCPs) on the provision of these interventions in the United Kingdom. A total of 177 HCPs participated in an online survey. Significant differences were found between medical and allied HCPs’ views on: whether HCPs adhere to policy and accept legal constraints when it comes to making gastrostomy available to people with ALS; the impressions that HCPs receive of the way patients and caregivers understand the effects of gastrostomy and NIV on symptoms and quality of life; and the challenges HCPs face when caring for patients who have refused gastrostomy. More widely available guidelines for the provision of gastrostomy and advice on the best way to impart information to patients and caregivers about gastrostomy and NIV appear to be needed.

Abstract
Given the significant impact that psychosocial factors and epilepsy treatments can have on the health-related quality of life (HRQOL) of individuals with epilepsy and their families, there is great clinical interest in the role of psychological evaluation and treatments to improve HRQOL and comorbidities. Therefore, the International League Against Epilepsy (ILAE) charged the Psychology Task Force with the development of recommendations for clinical care based on evaluation of the evidence from their recent Cochrane review of psychological treatments in individuals with epilepsy. The literature search for a recent Cochrane review of randomized controlled trials investigating psychological treatments for individuals with epilepsy constitutes the key source of evidence for this article. To provide practical guidance to service providers, we provide ratings on study research designs based on (1) the American Academy of Neurology's Level of Evidence system and (2) the Grading of Recommendations, Assessment, Development, and Evaluation system. This paper is the culmination of an international collaboration process involving pediatric and adult psychologists, neurologists, psychiatrists, and neuropsychiatrists. The process and conclusions were reviewed and approved by the ILAE Executive Committee. The strongest evidence for psychological interventions was identified for the most common mental health problems, including depression, neurocognitive disturbances, and medication adherence. Psychological interventions targeting the enhancement of HRQOL and adherence and a decrease in comorbidity symptoms (anxiety, depression) should be incorporated into comprehensive epilepsy care. There is a range of psychological strategies (ie, cognitive behavioral therapy and mindfulness-based therapies) that show promise for improving the lives of persons with epilepsy, and clinical recommendations are provided to assist epilepsy health care providers in treating the comorbidities and challenges associated with epilepsy and its treatments.

Abstract
OBJECTIVE Epilepsy is one of the most common neurological conditions affecting about 1% of adults. Up to 40% of people with epilepsy (PWE) report recurring seizures while on medication. And optimal functioning requires good self-management. Our objective was to evaluate a group self-management education courses for people with epilepsy and drug-resistant seizures by means of a multicenter, pragmatic, parallel group, randomized controlled trial. METHODS We recruited adults with epilepsy, having ≥2 seizures in the prior 12 months, from specialist clinics. Consenting participants were randomized 1:1 to a group course or treatment as usual. The primary outcome measure was quality of life 12 months after randomization using Quality of Life 31-P (QOLIE-31-P). Secondary outcome measures were seizure frequency and recency, psychological distress, impact and stigma of epilepsy, self-mastery, medication adherence, and adverse effects. Analysis of outcomes followed the intention-to-treat principle using mixed-effects regression models. RESULTS We enrolled 404 participants (intervention: n = 205, control: n = 199) with 331 (82%) completing 12-month follow-up (intervention: n = 163, control: n = 168). Mean age was 41.7 years, ranging from 16 to 85, 54% were female and 75% were white. From the intervention arm, 73.7% attended all or some of the course. At 12-month follow-up, there were no statistically significant differences between trial arms in QOLIE-31-P (intervention mean: 67.4, standard deviation [SD]: 13.5; control mean: 69.5, SD 14.8) or in secondary outcome measures. SIGNIFICANCE This is the first pragmatic trial of group education for people with poorly controlled epilepsy. Recruitment, course attendance, and follow-up rates were higher than expected. The results show that the primary outcome and quality of life did not differ between the trial arms after 12 months. We found a high prevalence of felt-stigma and psychological distress in this group of people with drug-resistant seizures. To address this, social and psychological interventions require evaluation, and may be necessary before or alongside self-management-education courses.

Abstract
This study sought to extend knowledge about the previously reported preconscious attentional bias (AB) for facial emotion in patients with dissociative seizures (DS) by exploring whether the finding could be replicated, while controlling for concurrent anxiety, depression, and potentially relevant cognitive impairments. Patients diagnosed with DS (n=38) were compared with healthy controls (n=43) on a pictorial emotional Stroop test, in which backwardly masked emotional faces (angry, happy, neutral) were processed implicitly. The group with DS displayed a significantly greater AB to facial emotion relative to controls; however, the bias was not specific to negative or positive emotions. The group effect could not be explained by performance on standardized cognitive tests or self-reported depression/anxiety. The study provides additional evidence of a disproportionate and automatic allocation of attention to facial affect in patients with DS, including both positive and negative facial expressions. Such a tendency could act as a predisposing factor for developing DS initially, or may contribute to triggering individuals' seizures on an ongoing basis. Psychological interventions such as Cognitive Behavioral Therapy (CBT) or AB modification might be suitable approaches to target this bias in clinical practice.

Abstract
People with dissociative seizures (DS) report a range of difficulties in emotional functioning and exhibit altered responding to emotional facial expressions in experimental tasks. We extended this research by investigating subjective and autonomic reactivity (ratings of emotional valence, arousal and skin conductance responses [SCRs]) to general emotional images in 39 people with DS relative to 42 healthy control participants, whilst controlling for anxiety, depression, cognitive functioning and, where relevant, medication use. It was predicted that greater subjective negativity and arousal and increased SCRs in response to the affective pictures would be observed in the DS group. The DS group as a whole did not differ from controls in their subjective responses of valence and arousal. However, SCR amplitudes were greater in ‘autonomic responders’ with DS relative to ‘autonomic responders’ in the control group. A positive correlation was also observed between SCRs for highly arousing negative pictures and self‐reported ictal autonomic arousal, in DS ‘autonomic responders’. In the DS subgroup of autonomic ‘non‐responders’, differences in subjective responses were observed for some conditions, compared to control ‘non‐responders’. The findings indicate unaffected subjective responses to emotional images in people with DS overall. However, within the group of people with DS, there may be subgroups characterized by differences in emotional responding. One subgroup (i.e., ‘autonomic responders’) exhibit heightened autonomic responses but intact subjective emotional experience, whilst another subgroup (i.e., ‘autonomic non‐responders’) seem to experience greater subjective negativity and arousal for some emotional stimuli, despite less frequent autonomic reactions. The current results suggest that therapeutic interventions targeting awareness and regulation of physiological arousal and subjective emotional experience could be of value in some people with this disorder.

Abstract
BACKGROUND Given the significant impact epilepsy can have on the health-related quality of life (HRQoL) of individuals with epilepsy and their families, there is great clinical interest in evidence-based psychological treatments, aimed at enhancing psychological well-being in people with epilepsy. A review of the current evidence was needed to assess the effects of psychological treatments for people with epilepsy on HRQoL outcomes, in order to inform future therapeutic recommendations and research designs. OBJECTIVES To assess the effects of psychological treatments for people with epilepsy on HRQoL outcomes. SEARCH METHODS We searched the following databases on 20 September 2016, without language restrictions: Cochrane Epilepsy Group Specialized Register, CENTRAL, MEDLINE PsycINFO, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform (ICTRP). We screened the references from included studies and relevant reviews, and contacted researchers in the field for unpublished studies. SELECTION CRITERIA We considered randomized controlled trials (RCTs) and quasi-RCTs for this review. HRQoL was the main outcome measure. For the operational definition of 'psychological treatments', we included a broad range of treatments that used psychological or behavioral techniques designed to improve HRQoL, seizure frequency and severity, and psychiatric comorbidities for adults and children with epilepsy, compared to treatment as usual (TAU) or an active control group. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by the Cochrane Collaboration. MAIN RESULTS We included 24 completed RCTs, with a total of 2439 participants. Eleven studies investigated psychological interventions, such as cognitive, behavioral, and mindfulness-based interventions. The remaining studies were classified as educational interventions (N = 7), self-management interventions (N = 3), adherence interventions (N = 1), and mixed interventions (N = 2). Two studies investigated interventions for children and adolescents, and five studies investigated interventions for adolescents and adults. Based on satisfactory clinical and methodological homogeneity, we pooled data from six adult studies, two studies on adolescents and adults, and one on adolescents and young adults (468 participants) for HRQoL, measured with the Quality of Life in Epilepsy-31 (QOLIE-31). We found significant mean changes for the QOLIE-31 total score and six subscales (emotional well-being, energy and fatigue, overall QoL, seizure worry, medication effects, and cognitive functioning). The mean changes of the QOLIE-31 total score (mean improvement of 5.68 points (95% CI 3.11 to 8.24; P < 0.0001), and three subscales, emotional well-being (mean improvement of 7.03 points (95% CI 2.51 to 11.54; P = 0.002); energy and Fatigue (mean improvement of 6.90 points (95% CI 3.49 to 10.31; P < 0.0001); and overall QoL (mean improvement of 6.47 points (95% CI 2.68 to 10.25; P = 0.0008) exceeded the threshold of minimally important change (MIC), indicating a clinically meaningful post-intervention improvement of QoL. We downgraded the quality of the evidence provided by the meta-analysis because of serious risk of bias in some of the included studies. Consequentially, these results provided evidence of moderate quality that psychological treatments for adults with epilepsy may enhance overall QoL in people with epilepsy. AUTHORS' CONCLUSIONS Implications for practice: Psychological interventions and self-management interventions improved QoL, and emotional well-being, and reduced fatigue in adults and adolescents with epilepsy. Adjunctive use of psychological treatments for adults and adolescents with epilepsy may provide additional benefits to QoL in those who incorporate patient-centered management. IMPLICATIONS FOR RESEARCH Authors should strictly adhere to the CONSORT guidelines to improve the quality of reporting on their interventions. A thorough description of the intervention protocol is necessary to ensure reproducibility.When researching psychological treatments for people with epilepsy, the use of Quality of Life in Epilepsy Inventories (QOLIE-31, QOLIE-31-P, and QOLIE-89) would increase comparability. There is a critical gap in pediatric RCTs for psychological treatments, particularly those that use an epilepsy-specific measure of HRQoL.Finally, in order to increase the overall quality of study designs, adequate randomization with allocation concealment and blinded outcome assessment should be pursued when conducting RCTs. As attrition is often high in research that requires active participant participation, an intention-to-treat analysis should be carried out.
