When evaluating a patient with suspected PNES in an out- or inpatient setting, there are a variety of clinician behaviors that can support or obstruct the establishment of a positive therapeutic alliance. Similarly, a number of typical patient characteristics in PNES can affect the psychiatric assessment. In this chapter, these characteristics and behaviors are discussed, a clinician checklist is provided, and dialogue boxes illustrate a few common patient–clinician interactions, hypothetical challenges, and clinician responses. Distinctive challenges, including interaction with specific PNES subtypes (i.e., developmentally delayed, malingering, or hostile patients) and patients who are effectively incapacitated by high event frequency and systemic barriers, are presented.

The quality of life (QOL) in patients with PNES is reportedly low and trauma eems to be a relevant risk factor. The objective of this study was to examine the difference between measures of (epilepsy-specific) QOL (Quality of Life in Epilepsy Inventory; QOLIE-31p) and psychological dysfunction (trauma symptom inventory; TSI) between patients with diagnosed PNES with self-reported trauma and those without self-reported trauma. Methods: Patients whose PNES diagnoses were through video-electroencephalogram (EEG) monitoring at the Northeast Regional Epilepsy Group between 2008 and 2018 were included. Patients who reported to have a history of psychological trauma and those who did not were assigned to separate groups. Scores from the TSI and QOLIE-31p were compared by using multivariate analysis of covariance. Results: The total sample was comprised of 217 adult patients, 148 of which self-reported as having experienced psychological trauma in the past and 69 who did not report any psychological trauma. Traumatized patients significantly differed in terms of QOL and TSI from nontraumatized patients. Traumatized patients were demonstrated to have lower scores on the subdomain "energy" of the QOLIE-31p and the total QOLIE-31p score compared to the nontraumatized group. Similarly, the traumatized group had significantly higher scores on nearly all TSI subscales with the exception of suicidality, sexual disturbances, and somatization. Conclusion: This study demonstrated significant differences between patients with PNES who have been psychologically traumatized and those who have not. In particular, patients with a history of psychological trauma present greater psychopathology and would possibly benefit from rapid identification and referral to traumabased therapy. In turn, this may result in a reduction of disease burden, increase QOL, and a reduction in healthcare costs resulting from diagnostic delays and implementation of less targeted treatments.

Instead, these episodes, which tend to occur with alterations in consciousness and body movements, are thought to be the result of mechanisms of conversion and dissociation. Psychological trauma and PTSD are very prevalent among patients with PNES. PNES can be conceived of as an extreme avoidance mechanism that serves the function of modulating distress and, in some cases, eliminating the precipitant stressor. Avoidance is also an essential component of PTSD. In patients who carry a dual diagnosis of PNES and PTSD, it is sensible that an empirically validated treatment for PTSD such as prolonged exposure (PE) therapy which targets avoidance by promoting exposure might be a useful approach to treat these patients. In this report, we present the case of a 52-yearold male with a 7-year history of PNES. His seizures, which were characterized by intense body shaking and loud guttural outbursts, were occurring up to 15 times per day. Because of these symptoms, he lost his employment and was ostracized by his family. Upon completion of a course of intensive outpatient PE, he achieved full remission of all psychogenic symptoms. Except for three brief seizures, he has maintained his health for 2 years. This constitutes the first detailed report of PE therapy used to effectively treat comorbid PNES and posttraumatic stress symptoms.

The second aim of the study was to investigate the relationship between validity indicators from the cognitive battery with validity and clinical scales from a personality scale. METHOD Patients with PNES (N = 250; F:M 186:64; mean age 38.32 (13.23)) were assessed utilizing the RBANS (Czech Research version) to evaluate cognitive performance and to obtain the Effort Index. The MMPI-2 was used to evaluate personality and psychopathology. RESULTS Global cognitive performance was 0.92 SD below average (according to the Gaussian distribution) in patients with PNES. The lowest scores in the sample were in the Attention domain (-1.7SD). Insufficient effort was detected in 10% of patients. Education correlated negatively with the Effort index (rs = -0.25, p = 0.01). A mild significant correlation in Scale 7 (rs = 0.21, p = 0.01) and Scale 8 (rs = 0.24, p = 0.01), and a significant correlation between Effort Index and Back F Scale (rs = 0.23, p = 0.01) were noted. CONCLUSIONS Assessment of cognitive performance and effort is an essential part of the comprehensive evaluation of patients with PNES during their hospitalization at Epilepsy centers. Many aspects of the neuropsychological assessment can offer useful indications for reaching a differential diagnosis, including clinical history, behavioral observations, cognitive and symptom validity testing, and structured psychological inventories.

Background: A handful of studies have examined outcome of patients once the diagnosis of PNES has been communicated. However, the vast majority of these have been conducted in the first world countries with samples that were predominantly Caucasian. There is limited knowledge about outcome in economically disadvantaged Latin American patients diagnosed as having PNES. Methods: This is a study of 23 patients (20 women, 3 men) with PNES in which demographic data (age, education, nationality, presence of psychological trauma, age of onset) were retrospectively retrieved from medical files. Follow-up was done through a telephonic questionnaire in which investigators collected clinical information (seizure characteristics at follow-up, and treatments employed) and changes in demographic data. Results: Patients from this Argentinian PNES sample demonstrated having many similar demographic and clinical characteristics to samples from US and European studies. Long-term follow-up revealed, however, decreased seizure frequency and intensity as well as a substantial improvement in occupational status. A majority had engaged in psychotherapy as well as alternative and complementary approaches. A majority had also developed what are suspected to be other functional symptoms. Conclusions: Argentinian patients from economically disadvantaged backgrounds, diagnosed as having PNES reported improvements in seizure frequency and occupational status during long-term follow-up. Future studies will need to focus on what (e.g., communication of diagnosis, psychotherapy, alternative treatments) may have contributed to these changes.

BACKGROUND The typical age for PNES onset is roughly between 20 and 40 years of age. Only a handful of studies have examined samples with PNES onset at an older age and therefore information about these individuals is limited. METHODS This is a retrospective study of 75 consecutive individuals who developed (video EEG-confirmed diagnosis) PNES before age 50 years and 55 consecutive individuals who developed PNES at 50 years or more. Patients were examined on demographics (age, education, working and relationship status), clinical (seizure frequency, trauma type: sexual, multiple trauma, and health-related traumatic experiences), and self-report measures(Coping Inventory for Stressful Situations, Toronto Alexithymia Scale, and the Quality of Life Inventory in Epilepsy-31). RESULTS Patients who had experienced sexual trauma were likelier to develop PNES at an earlier age. Those who experienced "health problems pre-PNES onset" were likelier to develop PNES at an older age. On psychological measures, it was noted that after adjusting for the covariate effects, those with elevations in Avoidance (CISS) were likelier to develop PNES at an earlier age. and those with elevations in QOLIE31 cognitive complaints were likelier to be in the older cohort. CONCLUSIONS No matter at what age PNES presented, patients reported markedly high rates of exposure to psychological trauma (single and multiple), similarly elevated unemployment rates and low quality of life. The groups with different age of onset differed in the type of trauma experienced prior to the development of PNES. In addition, the younger onset group demonstrated a significantly higher use of avoidance as a stress-coping strategy.

The purpose of this study was to determine if patients with comorbid PTSD differ from other patients with PNES in terms of alexithymia and stress coping strategies. Methods: 156 adult patients with video-EEG confirmed PNES were assessed with the Trauma Symptom Inventory-2 (TSI-2) and diagnostic clinical interview, Toronto Alexithymia Scale (TAS-20), and the Coping Inventory for Stressful Situations (CISS). There were 3 groups: 48 patients with PTSD, 62 patients who had experienced trauma and did not have PTSD, and 46 patients who denied experiencing trauma. Results: One-way ANCOVA revealed a significant difference between groups on reported levels of alexithymia [F(2, 154) = 18.21, p < .001] and use of emotion-focused coping [F(2, 156) = 11.12, p < .001]. Tukey HSD post-hoc comparisons indicated that the PNES/PTSD group had significantly higher mean alexithymia scores (M = 59.54, SD = 12.89) than both the no trauma (M = 49.51, SD = 14.92) and the trauma with no PTSD groups (M = 49.98, SD = 13.27), which did not differ from each other. The PNES/PTSD group was also significantly more likely (M = 62.44, SD = 11.56) than the no trauma (M = 52.87, SD = 13.57) and the trauma with no PTSD groups (M = 52.06, SD = 12.63) to utilize emotion-focused coping strategies. No significant differences were found between groups on use of task-or avoidance-focused coping. Conclusion: The study revealed elevated alexithymia and use of potentially more maladaptive emotionfocused coping strategies among patients with PNES and comorbid PTSD. These findings highlight discrete areas to target in treatment depending on comorbid symptomatology, and suggests that PNES, which is often regarded as a homogeneous entity, appears to encompass distinct subgroups.

Background: Psychogenic nonepileptic seizures are overrepresented by females; therefore, information about PNES in males is limited. Only a handful of studies have examined PNES and gender, and of those, one was a literature review and with the exception of two, most have had small sample sizes. Of the existing literature, differences in abuse type, psychiatric diagnoses, and psychometric results have been observed in the two genders. Methods: This is a retrospective study of 51 consecutive males and 97 consecutive females with video-electroencephalogram (video-EEG) confirmed diagnosis of PNES. Patients were examined on demographics (age, education, working status), clinical (seizure frequency, trauma type: sexual, nonsexual, age of first trauma), and psychometric measures. The latter included the State Trait Anger Expression Inventory-2 (STAXI-2), Trauma Symptom Inventory-2 (TSI-2), the Coping Inventory for Stressful Situations (CISS), and the Quality of Life Inventory in Epilepsy-31 (QOLIE-31). Results: Women reported experiencing significantly more sexual traumas (p = 0.007) than men. Women also endorsed significantly higher levels of dissociation (p = 0.012) and sexual disturbances (p = 0.46). In contrast, men reported significantly greater use of avoidance (p = 0.001) as a stress coping strategy and higher levels of depression (p = 0.006). Conclusions: Gender differences were identified with males reporting a significantly higher use of avoidance (cognitive and behavioral avoidance of stress) and depressive symptoms. Women exhibited significantly higher rates of sexual trauma compared with male counterparts. Consequently, women also had significantly higher rates of trauma symptomatology (dissociation and sexual disturbances) which are often observed in those who have been traumatized sexually. These gender distinctions may support different first-line treatment approaches (e.g., traumafocused; more traditional cognitive behavioral therapy) depending on the most prominent symptomatology.

Instead, they are psychogenic in origin. These episodes tend to occur with alterations in consciousness and bodily functions and are the result of mechanisms of conversion. Psychological trauma and post-traumatic stress disorder (PTSD) are prevalent among patients with PNES. This is a case report of a 32-year-old male who began treatment 1-year after developing PTSD followed some months later by PNES. His seizures were characterized by contorted movements of the head and neck, guttural sounds, and left sided movements or whole-body arching and were accompanied by frequent falls and injuries. They were usually brief but occurred daily. Psychotherapy had been discontinued because violent seizures often interrupted the sessions. He was treated with prolonged exposure (PE) at a PNES program and by the last session, had achieved an improvement in his seizure frequency (one every 4-6 days rather than daily episodes). This allowed him to begin therapy with a local therapist. Two years after completing treatment, the patient returned for a follow up visit. At that point, his seizure frequency, was one per month which shows he sustained and improved on this symptom. Former head drops, and grunting sounds disappeared, and he was no longer using a cane to ambulate. From an emotional standpoint (PTSD, suicidality, anxiety, quality of life), the patient had achieved and maintained a much healthier level of functioning (though no change on alexithymia, anger, depression, and trait anxiety).

METHOD A retrospective study of 31 patients; 15 patients with PNES (11 females) and 16 patients with epilepsy (8 females) collected consecutively between 2014-2018. Demographic and clinical information (age of seizure onset, life adversities, individual/family psychiatric history, etc.) were gathered. Scales from the TSCC (Dissociation, Depression, Anxiety) were analyzed. RESULTS Eleven of the youth with PNES (YPNES) (73%) were female, mean age was 14.3 ± 1.6 years and years of education were 9 ± 1.9. Eight of the youth with epilepsy (YWE) (50%) were females, mean age was 11.9 ± 2.8 years and years of education were 5.6 ± 2.9. All 15 YPNES and over half of their families had comorbid psychological problems whilst rates of personal and family psychiatric histories were much lower in YWE. Well over half of YPNES reported experiencing life adversities while one fourth of YWE reported these types of experiences. Significant differences were observed between YPNES and YWE on TSCC Overt Dissociation (p < 0.003), Dissociation (p < 0.009), and Depression (p < 0.001) scales, with YWE producing lower scores. When the six target variables were condensed into one principal component, the global TSCC score was lower in the epilepsy group, even after adjusting for potential effects age, seizure frequency and intellectual quotient. CONCLUSIONS The current study's results indicate that YPNES present with comparably higher self-reported symptoms of depression and dissociation than YWE.

Methods: This was a prospective, open-label, nonblinded, adjunctive therapy test-retest (within subjects) study of patients with treatment-resistant partial epilepsy in which outcome (cognitive functioning and mood/quality of life) was measured in the same subject before and after adjunctive lacosamide administration for 24 weeks. The cognitive assessment included the following: Controlled Oral Word Association Test, Buschke Selective Reminding Test, Brief Visuospatial Memory Test-Revised, Stroop Color Word Test, Symbol Digit Modalities Test, Digit Span, Digit Cancellation, and Trails A and B. The quality-of-life measures/quality-of-life assessment included the following: Beck Depression Inventory-II, Profile of Mood States, and Quality of Life Inventory-89. Lacosamide was started at 100 mg (50 mg twice daily) and could be titrated as needed up to 400 mg/day (200 mg twice daily). Baseline concomitant AEDs were kept constant. Composite scores were calculated for a pre-post difference score for the cognitive and mood/quality-of-life measures separately and used in regression analyses to correct for the effects of age, education, seizure frequency, seizure severity, dose of lacosamide, and number of AEDs at baseline. Results: Thirty-four patients were enrolled (13 males, 21 females). Mean age was 38.8 ± 2.43 years. Mean seizure frequency decreased significantly from 2.0 ± 2.55 seizures per week at baseline to 1.02 ± 1.72 seizures per week at posttreatment (t = 4.59, p b .0001) with a 50% responder rate seen in 18 patients (52.9%). No significant differences were found on the composite scores of the cognitive or the mood/quality-of-life measures after 6 months of lacosamide. Significance: Lacosamide appeared to have low risks of significant changes in cognition or mood/quality of life. In addition, the present study supports prior studies that have proven lacosamide as an effective adjunctive therapy for the treatment of resistant partial epilepsy.

Psychotherapy is believed to be effective in identifying the etiology of the disorder and treating disorder-related comorbidities. However, there is as of yet no clear consensus on the psychotherapeutic methodology most effective in treating NES. In the current case report, group psychotherapy utilizing psychoeducation was employed. Results show clear declines in symptoms of trauma and dissociation and improved coping strategies and quality of life. [Brief Treatment and Crisis Intervention 4:343-352 (2004)]

H... more Psychogenic Nonepileptic Seizures (PNES) have been linked to dysregulated emotions and arousal. However, the question which emotions may be most relevant has received much less attention. In this multidisciplinary narrative review, we argue that the self-conscious emotion of shame is likely to be of particular importance for PNES. We summarize current concepts of the development of shame processing and its relationship with other emotional states. We demonstrate the potential of acute shame to cause a sudden disruption of normal cognitive function and trigger powerful behavioral, cognitive, physiological and secondary emotional responses which closely resemble key components of PNES. These responses may lead to the development of shame avoidance strategies which can become disabling in themselves. We discuss how excessive shame proneness and shame dysregulation are linked to several psychopathologies often associated with PNES (including depression and PTSD) and how they may predispose to, precipitate and perpetuate PNES disorders, not least by interacting with stigma. We consider current knowledge of the neurobiological underpinnings of shame and PNES. We explore how shame could be the link between PNES and a heterogeneous range of possible etiological factors, and how it may link historical aversive experiences with individual PNES events occurring much later and without apparent external trigger. We argue that, in view of the potential direct links between shame and PNES, the well-documented associations of shame with common comorbidities of this seizure disorder and the well-characterized relationship between chronic shame and stigma, there is a compelling case to pay greater attention to shame in relation to PNES. Its role in the treatment of patients with PNES is discussed in a separate, linked review incorporating case vignettes to highlight the complex interactions of different but interlinked shame-related issues in individual patients.

We provided an open-ended group psychotherapy program to 10 patients with PNES, including a disorder-specific psychoeducation treatment component in the first 10 weeks. Seizure frequency and questionnaire responses were examined pre-and posttreatment in all 7 of 10 individuals who completed the majority of the psychoeducational sessions. Four individuals experienced no change in seizure frequency; in three of these this was due to a cessation of events at treatment initiation. Two individuals experienced a decline; and one, an increase, in seizure frequency. Significant decreases were reported in posttraumatic (P ¼ 0:003) and dissociative (P ¼ 0:04) symptoms and emotionally based coping mechanisms (P ¼ 0:03). There was also a trend toward improved quality of life (P ¼ 0:07). Experience/expression of anger remained stable. Psychoeducation may be an effective method of treating PNES and may improve coping strategies and reduce PNES-associated psychopathology in some patients. Additional controlled studies on larger samples are needed.

In a companion article to this multidisciplinary narrative review, we have argued that, in the context of a biopsychosocial understanding of the condition, the emotion of shame is particularly likely to contribute to the aetiology, manifestation, semiology and perpetuation of psychogenic non-epileptic seizures (PNES). Here we demonstrate how unrecognised and unaddressed shame may cause difficulties when clinicians explain the diagnosis, attempt to engage patients in psychological treatment, construct a diagnostic formulation and undertake psychotherapy. Case vignettes are used to bring theoretical considerations to life and to illustrate the complex interactions which may be observed between high shame proneness, chronic and dysregulated shame, stigma and PNES. The particular focus on shame does not mean that recent explanatory models of PNES are obsolete. Rather, we demonstrate how the inclusion of shame helps to embed the emotional, cognitive and behavioural aspects of the Integrative Cognitive Model (ICM) of PNES in a social / interpersonal context. While we describe how a number of different psychotherapeutic approaches can help to address shame-related processes we conclude that specific modalities are less important than the eventual enhancement of emotional literacy and tolerance through a healing relationship with the psychotherapist.
Psychological assessment measures are frequently used to evaluate patients in epilepsy monitoring... more Psychological assessment measures are frequently used to evaluate patients in epilepsy monitoring units. One goal of that assessment is to contribute information that may help with differential diagnosis between epilepsy and psychogenic nonepileptic seizures (PNES). The Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) is one such measure. Del Bene et al. (2017) recently published an analysis that was the first to compare MMPI-2-RF scale elevations between diagnostic groups stratified by sex. The purpose of the present study was to replicate that analysis in a larger sample. Similar to previous work, we found that both men and women with PNES were more likely than men and women with epilepsy to report high levels of somatic complaints (2 to 5 times greater odds of somatic symptom reporting) and a variety of types of complaints. Mood disturbance scales were not significantly elevated in our PNES sample. Results contribute to the small body of research on sex differences in patients with PNES and suggest that somatization is a key characterization across sexes.

Patients were examined on demographics (age, education, working and relationship status), clinical (seizure frequency, trauma type: sexual, multiple trauma, and health-related traumatic experiences), and self-report measures(Coping Inventory for Stressful Situations, Toronto Alexithymia Scale, and the Quality of Life Inventory in Epilepsy-31). RESULTS Patients who had experienced sexual trauma were likelier to develop PNES at an earlier age. Those who experienced "health problems pre-PNES onset" were likelier to develop PNES at an older age. On psychological measures, it was noted that after adjusting for the covariate effects, those with elevations in Avoidance (CISS) were likelier to develop PNES at an earlier age. and those with elevations in QOLIE31 cognitive complaints were likelier to be in the older cohort. CONCLUSIONS No matter at what age PNES presented, patients reported markedly high rates of exposure to psychological trauma (single and multiple), similarly elevated unemployment rates and low quality of life. The groups with different age of onset differed in the type of trauma experienced prior to the development of PNES. In addition, the younger onset group demonstrated a significantly higher use of avoidance as a stress-coping strategy.

The purpose of this study was to determine if patients with comorbid PTSD differ from other patients with PNES in terms of alexithymia and stress coping strategies. Methods: 156 adult patients with video-EEG confirmed PNES were assessed with the Trauma Symptom Inventory-2 (TSI-2) and diagnostic clinical interview, Toronto Alexithymia Scale (TAS-20), and the Coping Inventory for Stressful Situations (CISS). There were 3 groups: 48 patients with PTSD, 62 patients who had experienced trauma and did not have PTSD, and 46 patients who denied experiencing trauma. Results: One-way ANCOVA revealed a significant difference between groups on reported levels of alexithymia [F(2, 154) = 18.21, p < .001] and use of emotion-focused coping [F(2, 156) = 11.12, p < .001]. Tukey HSD post-hoc comparisons indicated that the PNES/PTSD group had significantly higher mean alexithymia scores (M = 59.54, SD = 12.89) than both the no trauma (M = 49.51, SD = 14.92) and the trauma with no PTSD groups (M = 49.98, SD = 13.27), which did not differ from each other. The PNES/PTSD group was also significantly more likely (M = 62.44, SD = 11.56) than the no trauma (M = 52.87, SD = 13.57) and the trauma with no PTSD groups (M = 52.06, SD = 12.63) to utilize emotion-focused coping strategies. No significant differences were found between groups on use of task-or avoidance-focused coping. Conclusion: The study revealed elevated alexithymia and use of potentially more maladaptive emotionfocused coping strategies among patients with PNES and comorbid PTSD. These findings highlight discrete areas to target in treatment depending on comorbid symptomatology, and suggests that PNES, which is often regarded as a homogeneous entity, appears to encompass distinct subgroups.

Background: Psychogenic nonepileptic seizures are overrepresented by females; therefore, information about PNES in males is limited. Only a handful of studies have examined PNES and gender, and of those, one was a literature review and with the exception of two, most have had small sample sizes. Of the existing literature, differences in abuse type, psychiatric diagnoses, and psychometric results have been observed in the two genders. Methods: This is a retrospective study of 51 consecutive males and 97 consecutive females with video-electroencephalogram (video-EEG) confirmed diagnosis of PNES. Patients were examined on demographics (age, education, working status), clinical (seizure frequency, trauma type: sexual, nonsexual, age of first trauma), and psychometric measures. The latter included the State Trait Anger Expression Inventory-2 (STAXI-2), Trauma Symptom Inventory-2 (TSI-2), the Coping Inventory for Stressful Situations (CISS), and the Quality of Life Inventory in Epilepsy-31 (QOLIE-31). Results: Women reported experiencing significantly more sexual traumas (p = 0.007) than men. Women also endorsed significantly higher levels of dissociation (p = 0.012) and sexual disturbances (p = 0.46). In contrast, men reported significantly greater use of avoidance (p = 0.001) as a stress coping strategy and higher levels of depression (p = 0.006). Conclusions: Gender differences were identified with males reporting a significantly higher use of avoidance (cognitive and behavioral avoidance of stress) and depressive symptoms. Women exhibited significantly higher rates of sexual trauma compared with male counterparts. Consequently, women also had significantly higher rates of trauma symptomatology (dissociation and sexual disturbances) which are often observed in those who have been traumatized sexually. These gender distinctions may support different first-line treatment approaches (e.g., traumafocused; more traditional cognitive behavioral therapy) depending on the most prominent symptomatology.

Instead, they are psychogenic in origin. These episodes tend to occur with alterations in consciousness and bodily functions and are the result of mechanisms of conversion. Psychological trauma and post-traumatic stress disorder (PTSD) are prevalent among patients with PNES. This is a case report of a 32-year-old male who began treatment 1-year after developing PTSD followed some months later by PNES. His seizures were characterized by contorted movements of the head and neck, guttural sounds, and left sided movements or whole-body arching and were accompanied by frequent falls and injuries. They were usually brief but occurred daily. Psychotherapy had been discontinued because violent seizures often interrupted the sessions. He was treated with prolonged exposure (PE) at a PNES program and by the last session, had achieved an improvement in his seizure frequency (one every 4-6 days rather than daily episodes). This allowed him to begin therapy with a local therapist. Two years after completing treatment, the patient returned for a follow up visit. At that point, his seizure frequency, was one per month which shows he sustained and improved on this symptom. Former head drops, and grunting sounds disappeared, and he was no longer using a cane to ambulate. From an emotional standpoint (PTSD, suicidality, anxiety, quality of life), the patient had achieved and maintained a much healthier level of functioning (though no change on alexithymia, anger, depression, and trait anxiety).

METHOD A retrospective study of 31 patients; 15 patients with PNES (11 females) and 16 patients with epilepsy (8 females) collected consecutively between 2014-2018. Demographic and clinical information (age of seizure onset, life adversities, individual/family psychiatric history, etc.) were gathered. Scales from the TSCC (Dissociation, Depression, Anxiety) were analyzed. RESULTS Eleven of the youth with PNES (YPNES) (73%) were female, mean age was 14.3 ± 1.6 years and years of education were 9 ± 1.9. Eight of the youth with epilepsy (YWE) (50%) were females, mean age was 11.9 ± 2.8 years and years of education were 5.6 ± 2.9. All 15 YPNES and over half of their families had comorbid psychological problems whilst rates of personal and family psychiatric histories were much lower in YWE. Well over half of YPNES reported experiencing life adversities while one fourth of YWE reported these types of experiences. Significant differences were observed between YPNES and YWE on TSCC Overt Dissociation (p < 0.003), Dissociation (p < 0.009), and Depression (p < 0.001) scales, with YWE producing lower scores. When the six target variables were condensed into one principal component, the global TSCC score was lower in the epilepsy group, even after adjusting for potential effects age, seizure frequency and intellectual quotient. CONCLUSIONS The current study's results indicate that YPNES present with comparably higher self-reported symptoms of depression and dissociation than YWE.

Methods: This was a prospective, open-label, nonblinded, adjunctive therapy test-retest (within subjects) study of patients with treatment-resistant partial epilepsy in which outcome (cognitive functioning and mood/quality of life) was measured in the same subject before and after adjunctive lacosamide administration for 24 weeks. The cognitive assessment included the following: Controlled Oral Word Association Test, Buschke Selective Reminding Test, Brief Visuospatial Memory Test-Revised, Stroop Color Word Test, Symbol Digit Modalities Test, Digit Span, Digit Cancellation, and Trails A and B. The quality-of-life measures/quality-of-life assessment included the following: Beck Depression Inventory-II, Profile of Mood States, and Quality of Life Inventory-89. Lacosamide was started at 100 mg (50 mg twice daily) and could be titrated as needed up to 400 mg/day (200 mg twice daily). Baseline concomitant AEDs were kept constant. Composite scores were calculated for a pre-post difference score for the cognitive and mood/quality-of-life measures separately and used in regression analyses to correct for the effects of age, education, seizure frequency, seizure severity, dose of lacosamide, and number of AEDs at baseline. Results: Thirty-four patients were enrolled (13 males, 21 females). Mean age was 38.8 ± 2.43 years. Mean seizure frequency decreased significantly from 2.0 ± 2.55 seizures per week at baseline to 1.02 ± 1.72 seizures per week at posttreatment (t = 4.59, p b .0001) with a 50% responder rate seen in 18 patients (52.9%). No significant differences were found on the composite scores of the cognitive or the mood/quality-of-life measures after 6 months of lacosamide. Significance: Lacosamide appeared to have low risks of significant changes in cognition or mood/quality of life. In addition, the present study supports prior studies that have proven lacosamide as an effective adjunctive therapy for the treatment of resistant partial epilepsy.

Psychotherapy is believed to be effective in identifying the etiology of the disorder and treating disorder-related comorbidities. However, there is as of yet no clear consensus on the psychotherapeutic methodology most effective in treating NES. In the current case report, group psychotherapy utilizing psychoeducation was employed. Results show clear declines in symptoms of trauma and dissociation and improved coping strategies and quality of life. [Brief Treatment and Crisis Intervention 4:343-352 (2004)]

H... more Psychogenic Nonepileptic Seizures (PNES) have been linked to dysregulated emotions and arousal. However, the question which emotions may be most relevant has received much less attention. In this multidisciplinary narrative review, we argue that the self-conscious emotion of shame is likely to be of particular importance for PNES. We summarize current concepts of the development of shame processing and its relationship with other emotional states. We demonstrate the potential of acute shame to cause a sudden disruption of normal cognitive function and trigger powerful behavioral, cognitive, physiological and secondary emotional responses which closely resemble key components of PNES. These responses may lead to the development of shame avoidance strategies which can become disabling in themselves. We discuss how excessive shame proneness and shame dysregulation are linked to several psychopathologies often associated with PNES (including depression and PTSD) and how they may predispose to, precipitate and perpetuate PNES disorders, not least by interacting with stigma. We consider current knowledge of the neurobiological underpinnings of shame and PNES. We explore how shame could be the link between PNES and a heterogeneous range of possible etiological factors, and how it may link historical aversive experiences with individual PNES events occurring much later and without apparent external trigger. We argue that, in view of the potential direct links between shame and PNES, the well-documented associations of shame with common comorbidities of this seizure disorder and the well-characterized relationship between chronic shame and stigma, there is a compelling case to pay greater attention to shame in relation to PNES. Its role in the treatment of patients with PNES is discussed in a separate, linked review incorporating case vignettes to highlight the complex interactions of different but interlinked shame-related issues in individual patients.

We provided an open-ended group psychotherapy program to 10 patients with PNES, including a disorder-specific psychoeducation treatment component in the first 10 weeks. Seizure frequency and questionnaire responses were examined pre-and posttreatment in all 7 of 10 individuals who completed the majority of the psychoeducational sessions. Four individuals experienced no change in seizure frequency; in three of these this was due to a cessation of events at treatment initiation. Two individuals experienced a decline; and one, an increase, in seizure frequency. Significant decreases were reported in posttraumatic (P ¼ 0:003) and dissociative (P ¼ 0:04) symptoms and emotionally based coping mechanisms (P ¼ 0:03). There was also a trend toward improved quality of life (P ¼ 0:07). Experience/expression of anger remained stable. Psychoeducation may be an effective method of treating PNES and may improve coping strategies and reduce PNES-associated psychopathology in some patients. Additional controlled studies on larger samples are needed.

In a companion article to this multidisciplinary narrative review, we have argued that, in the context of a biopsychosocial understanding of the condition, the emotion of shame is particularly likely to contribute to the aetiology, manifestation, semiology and perpetuation of psychogenic non-epileptic seizures (PNES). Here we demonstrate how unrecognised and unaddressed shame may cause difficulties when clinicians explain the diagnosis, attempt to engage patients in psychological treatment, construct a diagnostic formulation and undertake psychotherapy. Case vignettes are used to bring theoretical considerations to life and to illustrate the complex interactions which may be observed between high shame proneness, chronic and dysregulated shame, stigma and PNES. The particular focus on shame does not mean that recent explanatory models of PNES are obsolete. Rather, we demonstrate how the inclusion of shame helps to embed the emotional, cognitive and behavioural aspects of the Integrative Cognitive Model (ICM) of PNES in a social / interpersonal context. While we describe how a number of different psychotherapeutic approaches can help to address shame-related processes we conclude that specific modalities are less important than the eventual enhancement of emotional literacy and tolerance through a healing relationship with the psychotherapist.

One goal of that assessment is to contribute information that may help with differential diagnosis between epilepsy and psychogenic nonepileptic seizures (PNES). The Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) is one such measure. Del Bene et al. (2017) recently published an analysis that was the first to compare MMPI-2-RF scale elevations between diagnostic groups stratified by sex. The purpose of the present study was to replicate that analysis in a larger sample. Similar to previous work, we found that both men and women with PNES were more likely than men and women with epilepsy to report high levels of somatic complaints (2 to 5 times greater odds of somatic symptom reporting) and a variety of types of complaints. Mood disturbance scales were not significantly elevated in our PNES sample. Results contribute to the small body of research on sex differences in patients with PNES and suggest that somatization is a key characterization across sexes.
