Abstract
BACKGROUND Shame, a complex social emotion, may play a clinically important role in seizure disorders. Therefore, this study examined levels of shame aversion & shame proneness and their relationship with various mental health difficulties (MHDs), and seizure frequency & severity in people with functional seizures (PWFS) and epilepsy (PWE). METHODS In this cross-sectional study, PWFS (N = 68) and PWE (N = 70) were recruited through a neurology clinic and charities, completed online self-reported measures of shame proneness & aversion, seizure frequency & severity, depression, anxiety, somatic symptoms, and perceived socioeconomic status (PSS). Data analyses involved t-tests, correlations, and moderated regression analyses. RESULTS Both PWFS and PWE showed high and equivalent levels of shame aversion & proneness; mean levels of these measures were more than a standard deviation higher in PWFS and PWE, than in non-clinical populations of previous studies. Both groups had clinically high levels of depression and somatic symptoms, but not anxiety, with PWFS having significantly higher levels than PWE. Shame aversion predicted anxiety and depression in both groups, even after controlling for PSS, age, and gender. Interestingly, PSS, a demographic control variable, significantly predicted depression, anxiety, somatic symptoms, and seizure frequency in both groups. CONCLUSION We observed high levels of shame and MHDs in PWFS and PWE. Shame aversion predicted anxiety and depression in both groups, even after controlling for demographic variables. Our findings underline the significant role of shame in people with seizures, despite the differences between PWFS and PWE being smaller than expected.

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
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.
