The effect of attachment style on long-term outcomes in psychogenic nonepileptic seizures: Results from a prospective study

Negative impact of self-reported executive problems in patients with functional/dissociative seizures: Results from a prospective long-term observational study

OBJECTIVE

Functional/dissociative seizures (FDS) are common and pose a considerable burden on both individual patients and healthcare systems. Cognitive complaints are frequent in patients with FDS. Previous studies on cognitive function in patients with FDS have yielded mixed results. We investigated executive function and its impact on long-term outcome in a prospective sample of patients with FDS.

METHODS

Thirty-three inpatients (age range: 16-62 years) who had been admitted to the National Centre for Epilepsy in Norway with FDS underwent neuropsychological assessment for both tested and self-reported executive function, using the Behavior Rating Inventory of Executive Function, at baseline. Participants were evaluated for their medical status at a mean of 5.5 years (SD 2.4, range 1.9-10.9 years) after inclusion. To determine potential predictors of achieving cessation of FDS by time of follow-up a multivariate logistic regression analysis was conducted.

RESULTS

At follow-up, 14/33 (42 %) of the participants were FDS-free. Self-reported, but not tested, executive dysfunction was an independent risk factor for ongoing FDS at follow-up.

CONCLUSION

Our findings indicate an association between greater self-reported executive problems and poorer long term outcomes in patients with FDS. Screening for executive dysfunction with a self-report questionnaire may yield relevant information that could be used to guide psychological interventions.

A Multidisciplinary Approach to Nonepileptic Events

OBJECTIVE

This article provides a guide for neurologists managing nonepileptic events (NEEs), a complex intersection of neurology and psychiatry. It covers risk factors, pathophysiology, current treatment approaches, and prognosis, with specific management strategies for challenging scenarios such as patients with intellectual disabilities and comorbid epilepsy.

LATEST DEVELOPMENTS

An emphasis on strong communication and coordinated care among health care specialists improves patient outcomes and reduces unnecessary medical consultations and procedures. This approach is now recognized as essential for addressing the complex presentation and comorbidities associated with NEEs.

ESSENTIAL POINTS

NEEs are prevalent and highly disabling, and multiple pathophysiologic mechanisms for these events have been proposed. Mortality is comparable with that of patients with treatment-refractory epilepsy, and prognosis is better for children than adults. Achievable treatment goals for adults include improved quality of life and reduced frequency and severity of events, even if complete remission of NEEs is not achieved. Enhanced communication and coordinated care through multidisciplinary care teams enable the efficient use of individual expertise at different treatment stages to address the presentation, risk factors, and comorbidities associated with NEEs, resulting in a better quality of life for patients.

Associations between violent and sexual childhood trauma and maladaptive coping in patients with functional seizures

OBJECTIVE

Functional seizures (FS) are a highly debilitating symptom of functional neurological disorder (FND). FS requires a multi-disciplinary approach to treatment because the patient's initial presentation is to neurology, emergency medicine, or primary care and treatment consists of psychotherapy. People with FS commonly experience severe childhood trauma, particularly sexual trauma. The authors aimed to investigate associations between reported trauma and maladaptive coping mechanisms in the FS population.

METHODS

This retrospective, observational study reports on 137 patients enrolled in the FS Clinic at the University of Colorado between March 2020 - March 2021. Multiple linear regression was used to reveal associations between self-reported childhood sexual and violent trauma and maladaptive coping mechanisms of self-blame and disengagement on the Brief COPE. A quantile regression was generated for each of these outcomes.

RESULTS

Results showed that violent and sexual trauma were experienced by 47.5% and 61.6% of the population sample, respectively. Of those exposed to violent trauma, 27.2% perceived it as extremely severe while 43.4% of those exposed to sexual trauma perceived it as extremely severe. Quantile regressions for self-blame and disengagement showed significance for the 25th percentile of those who experienced violent trauma. Self-blame was significantly associated with the 50th and 75th percentile of those exposed to sexual trauma.

CONCLUSIONS

This evidence supports the value of identifying trauma experienced by individuals with FS as it is associated with specific coping mechanisms that may affect treatment. Identifying prior trauma and resulting coping mechanisms can potentially assist in individualizing care for people with FS.

Psychological Factors Associated with Functional Tic-like Behaviours during the COVID-19 Pandemic

Functional tic-like behaviours (FTLB) are a female predominant functional neurological disorder that escalated in incidence during the SARS CoV2 pandemic. This study compared social and adaptive functioning, social media use, pandemic experiences, and psychiatric comorbidities between FTLB (n = 35), Tourette Syndrome (TS) (n = 22), and neurotypical (NT) (n = 25) participants ages 11 to 25 years. The psychiatric comorbidity burden for participants with FTLB was formidable, with frequencies ranging from 1.5 to 10 times higher for major depressive disorder and panic disorder compared to TS and NT participants. Borderline personality disorder (BPD), agoraphobia, social anxiety disorder, and generalized anxiety disorder were also significantly more common in FTLB compared to NT participants. Vulnerable attachment scores, social phobia and social interaction anxiety symptoms were higher in participants with FTLB than NT but not TS. Overall distress tolerance, resilient coping, suggestibility, hours on social media, and exposure to tic and TS content were not significantly different between groups. FTLB participants rated their mental health declined more severely during the pandemic than both TS and NT participants and were more likely to experience trouble sleeping, loneliness, and difficulty affording housing and food than NT participants. Participants with FTLB were significantly more likely to identify as gender minority people than TS and NT, though there were no significant differences based on gender identity in the study variables within the FTLB group. The association and potential pathways explaining how psychiatric disorders may be contributing to FTLB, and why certain groups appear at particular risk are discussed.

Death of a loved one: A potential risk factor for onset of functional seizures

Functional seizures (FS) are a symptom of Functional Neurological Disorder (FND), the second most common neurological diagnosis made worldwide. Childhood trauma is associated with the development of FS, but more research is needed to truly understand the effects of trauma on FS onset. A sample of 256 responses by adults with FS to the Childhood Traumatic Events Scale were analyzed using a Cox proportional hazard model. When investigating each unique childhood traumatic exposure and its associated self-reported severity together, experiencing death of a loved one and experiencing violence were significantly associated with FS onset, suggesting reduced time from trauma exposure to first FS. Death of a loved one in childhood is often overlooked as an influential risk factor for future development of serious mental illnesses such as FS. In this study we show death of a loved one in childhood should be considered as an influential traumatic experience and recommend FND researchers examine its prevalence in patient histories and the potential effects on attachment-related processes and clinical treatment formulations. We recommend future studies incorporate loss of a loved one during childhood (before age 18) in both quantitative and qualitative assessments of persons with FND.

Adverse life events in patients with functional seizures: Assessment in clinical practice and association with long-term outcome

BACKGROUND

A history of adverse life events (ALE) is a risk factor for functional seizures (FS). Their influence on long-term outcome remains unclear. International guidelines recommend assessing ALE in patients presenting with associated disorders. It is not clear to what extent patients evaluated for FS are regularly asked about ALE.

OBJECTIVES

We hypothesised that the presence of ALE would relate to worse outcome at follow-up and, that the rate of detection of ALE in clinical work-up would be inferior to that based on self-report questionnaires.

METHODS

53 patients with FS from the National Centre for Epilepsy in Norway, aged 16-62 years were included. Symptom severity, health-related quality of life (HRQoL), and antecedent ALE were assessed at baseline. Medical records were examined for disclosure of ALE. At a mean of 70.45 (SD 29.0, range 22-130) months after inclusion, participants were inquired about FS status, FS-related health care utilization and HRQoL.

FINDINGS

A history of emotional abuse documented in the medical record was an independent risk factor for worse HRQoL at follow-up. Prevalence of ALE documented in medical records was lower compared with rates measured by a self-report questionnaire.

CONCLUSIONS

These findings indicate an association between antecedent ALE and HRQoL years after diagnosis. A substantial proportion of the adverse life events by a self-report questionnaire had not been documented in the clinical records.

CLINICAL IMPLICATIONS

The supplemental use of a self-report questionnaire in the diagnostic work-up of patients with FS may be valuable for detecting ALE.

Effects of attachment styles, childhood traumas, and alexithymia in Turkish patients with epilepsy and functional seizures

INTRODUCTION

In this cross-sectional study, we used self-report scales to compare childhood traumas, attachment styles, and alexithymia among patients with functional seizures (FS) to patients with epilepsy and healthy controls. We also investigated risk factors associated with FS.

MATERIAL AND METHODS

A total of 44 patients with epilepsy, 14 patients with FS, and 25 healthy controls were included. All participants were over the age of 18 and were referred to the Baskent University Adana Epilepsy and Video-EEG Center. The patients underwent neurological examinations, brain MRIs, and video-EEG evaluations. Epileptic seizures were classified based on video EEG. The control group consisted of healthy individuals without neurological or psychiatric illness and a history of epileptic seizures or syncope. Beck Depression Inventory (BDI), Childhood Trauma Questionnaire (CTQ), Adult Attachment Scale (AAS), and Toronto Alexithymia Scale-20 (TAS-20) were applied to all participants.

RESULTS

Patients with FS had lower educational levels, higher rates of unemployment and single-marital status. The FS group had higher depression, childhood trauma, and alexithymia scores than the other groups. Furthermore, FS patients had a higher prevalence of avoidant attachment. The alexithymia and childhood trauma scores were both correlated with depression. Through the logistic regression analysis, childhood trauma scores and alexithymia were significant risk factors for FS.

CONCLUSION

The use of video-EEG for diagnosing FS can reduce the risk of misdiagnosis and inappropriate antiepileptic treatment. Psychiatric comorbidities, childhood traumas, and alexithymia are prevalent in patients with FS. Therefore, implementing a multidisciplinary treatment approach that addresses the psychological, medical, and social aspects of FS can significantly improve outcomes.

Attachment style of patients diagnosed with psychogenic non-epileptic seizures at a tertiary Epilepsy Center in the Czech Republic

OBJECTIVE

Quality and type of early relationships with primary caregivers is considered one of the key factors in the etiopathogenesis of many mental disorders including depression, anxiety, and conversion disorders. This study focused on the type and quality of attachment style in adult patients with psychogenic non-epileptic seizures (PNES).

MATERIALS AND METHODS

We evaluated the demographic data and profiles of PNES patients (n = 262) and group of healthy volunteers (n = 51) measured by the Parental Bonding Inventory (PBI) and Experiences in Close Relationships (ECR) and Experiences in Close Relationships-Relationship Structure (ECR-RS).

RESULTS

Significant differences in measured values between the two groups were identified; specifically, differences in the caregiver style-father and mother overprotection (PBI) was higher in the PNES group. The most frequent type of attachment in PNES was type 2 (preoccupied). Correlations between the PBI and ECR results were also found.

CONCLUSION

This study highlighted certain attachment styles in patients with PNES and statistically significant differences between patients with PNES and a healthy sample. Some correlations between the results of the questionnaires with socio-demographic factors were found. The identification of specific patterns in attachment may be useful for further use in reaching a differential diagnosis and administering tailored psychotherapy of patients with PNES.
