RESUMEN

Functional seizures (FS) can be debilitating and negatively impact quality of life. Yet intervention research for FS is limited, especially for youth. This study examined clinical characteristics and outcomes of youth with FS (13-23 years) presenting to a pediatric intensive interdisciplinary pain treatment (IIPT) program in the midwestern United States. Sixty youth (mean age = 16.5 years; 83.3 % female) met inclusion criteria. At intake, comorbid chronic pain, somatic symptoms, autonomic dysfunction, eating and weight disturbances, and mental health concerns were common. Despite this high symptom burden, youth with FS reported significant improvements in functioning measured with the Functional Disability Inventory, t(53) = 9.80, p <.001, d = 1.32; depression measured with the Center for Epidemiological Studies - Depression Scale for Children, t(53) = 6.76, p <.001, d = 0.91; anxiety measured with the Spence Children's Anxiety Scale, t(53) = 3.97, p < .001, d = 0.53; and catastrophizing measured with the Pain Catastrophizing Scale for Children, t(53) = 6.44, p <.001, d = 0.86, following completion of the program, suggesting that IIPT may be an effective treatment option for highly disabled and emotionally distressed youth with FS. Future research is needed to continue to refine best practices for youth with FS to reduce suffering and improve outcomes.

RESUMEN

OBJECTIVE: Patients with functional neurological symptom disorder (FNSD) report high rates of traumatization and have high levels of posttraumatic stress disorder (PTSD) symptoms. Psychotherapy is a mainstay of treatment for persons with FNSD. In this study, the investigators explored changes in PTSD symptoms and health-related quality of life after psychotherapy among persons with FNSD and examined factors contributing to these changes. METHODS: Data were prospectively collected for patients with FNSD attending a specialist outpatient psychotherapy service in the United Kingdom (N=210) as part of an ongoing routine service evaluation. Pre- and posttherapy questionnaires included self-report measures of PTSD symptoms (Posttraumatic Stress Disorder Checklist-Civilian version), depressive symptoms (Patient Health Questionnaire-9), anxiety symptoms (General Anxiety Disorder-7 scale), somatic symptoms (Patient Health Questionnaire-15), health-related quality of life (Short-Form Health Survey-36), and social functioning (Work and Social Adjustment Scale). Independent contributions to psychotherapy-related changes in PTSD symptoms and health-related quality of life were explored through multivariate analyses. RESULTS: All outcome measures revealed improvements after psychotherapy (p<0.001). Psychotherapy-related changes in depression and somatic symptoms and employment status at baseline explained 51% of the variance in PTSD symptom changes. Changes in PTSD symptoms, depressive symptoms, and somatic symptoms made independent contributions to improvements in health-related quality of life (R2=0.54). Improvements were unrelated to FNSD subtype (dissociative seizures or other FNSD), age, marital status, or number of sessions attended. CONCLUSIONS: Reductions in self-reported PTSD, depressive, anxiety, and somatic symptoms, as well as improved health-related quality of life, were observed among patients who received one or more sessions of psychotherapy. Randomized controlled trials of psychotherapy for patients with FNSD are warranted.

RESUMEN

BACKGROUND: The psychological underpinnings of functional neurological symptom disorders (FNSD) remain poorly understood. A disintegration of explicit and implicit information processing in patients with FNSD has previously been suggested; however, this suggestion has so far received little empirical support. Trauma and maladaptive schemas probably reinforce disintegration in FNSD. The present study explored the occurrence of maladaptive schemas and investigated the impact of trauma-related maladaptive schemas in patients with FNSD. METHODS: Forty-eight FNSD patients were assessed at the start of treatment using the Young Schema Questionnaire (YSQ-2) to explore maladaptive schemas. The Life Event Checklist (LEC-5) and the PTSD Checklist for DSM-5 (PCL-5) were used to explore trauma states, and the Sickness Impact Profile (SIP-68) was used to measure health dysfunction. RESULTS: The self-sacrifice schema scored within a clinically relevant range where no increased scores were found in other maladaptive schemas. Linear regression models showed a positive association between mistrust/abuse and severity of health dysfunction. DISCUSSION: Results suggest that maladaptive schemas play a modest role in FNSD at the start of treatment. It is suggested to examine the occurrence of maladaptive schemas in FNS-disordered patients with a longitudinal design.

RESUMEN

Background and purpose: Over the past year, many cases with newly onset or significantly exacerbated tic disorders were observed worldwide, where some aspects of the clinical presentation or the symptomatology were atypical for established tic diagnoses. Our purpose was to describe the atypical cases and raise relevant diagnostic issues. Methods: Consecutive cases with atypical tic presentations were documented. Results: Five atypical tic cases are described. These cases shared some common characteristics, most notably the fact that all of them had been exposed to online presentation of ticking behaviour on social media platforms prior to the de novo development or exacerbation of their tics. Even though the order of events suggests causality and therefore the diagnosis of a functional tic disorder, unambiguous criteria for classifying atypical tics as functional symptoms are lacking. Differentiating neurodevelopmental and functional tics in childhood is currently problematic. Conclusion: Based on the currently unresolved issues in differential diagnosis, the importance of watchful waiting and behavioural interventions is highlighted to avoid unwarranted pharmacotherapy.

RESUMEN

OBJECTIVE: Ictal semiology interpretation for differentiating psychogenic nonepileptic seizures (PNESs) and epileptic seizures (ESs) is important for the institution of appropriate treatment. Our objective was to assess the ability of different health care professionals (HCPs) or students to distinguish PNES from ES based on video-recorded seizure semiology. METHODS: This study was designed following the Standards for Reporting of Diagnostic Accuracy Studies (STARD) guidelines. We showed in a random mix 36 videos of PNES or ES (18 each) and asked 558 participants to classify each seizure. The diagnostic accuracy of various groups of HCPs or students for PNES versus ES was assessed, as well as the effect of patient age and sex. Measures of diagnostic accuracy included sensitivity, specificity, and area under the curve (AUC). RESULTS: The descending order of diagnostic accuracy (AUC) was the following (p ≤ 0.001): (1) neurologists and epileptologists; (2) neurology residents; (3) other specialists and nurses with experience in epilepsy; and (4) undergraduate medical students. Although there was a strong trend toward statistical difference, with AUC 95% confidence intervals (CIs) that were not overlapping, between epileptologists (95% CI 93, 97) compared to neurologists (95% CI 88, 91), and neurologists compared to electroencephalography technicians (95% CI 82, 87), multiple pairwise comparisons with the conservative Tukey-Kramer honest significant difference test revealed no statistical difference (p = 0.25 and 0.1, respectively). Patient age and sex did not have an effect on diagnostic accuracy in neurology specialists. CONCLUSION: Visual recognition of PNES by HCPs or students varies overall proportionately with the level of expertise in the field of neurology/epilepsy.

RESUMEN

Specialist paediatric services manage a variety of presentations of functional somatic symptoms. We aimed to describe the presentation and management of children and adolescents with somatic symptom and related disorders (SSRDs) requiring admission to a tertiary children's hospital with the objective of informing the development of a local clinical pathway. Patients admitted to any hospital department from May 2016 to November 2017 were identified through an electronic medical record (EMR)-linked diagnosis of SSRD. Each record was reviewed for demographic details and admission histories. The frequency of interspecialty consultations and multidisciplinary team (MDT) family meetings were recorded. One hundred twenty-three patients with SSRD were admitted on 203 occasions to 17 different departments. The median (range) age was 14.3 (7.3-18.3) years. Interspecialty consultations occurred in 84.6% of patients, and MDT family meetings occurred in 18.9% patients. SSRD was diagnosed as an inpatient in 79.9% patients, yet only 40.7% of patients, including those with multiple admissions, had SSRD recorded as a discharge diagnosis.Conclusion: Despite high rates of consultation with hospital teams, the frequency of MDT family meetings was low, and less than half the patients had SSRD documented at discharge. This affirms the value of developing a local clinical pathway. What is Known • Functional somatic symptoms are commonly seen in children and adolescents. • Few studies have explored the reach of functional somatic symptoms across a tertiary paediatric hospital; the majority of inpatient studies have focused on a limited set of disorders or cases referred to psychiatry departments. What is New • Symptoms that spanned multiple body systems were the most common presentation of SSRDs in admitted children and adolescents. • Somatic symptom disorders are less likely to be recorded as a discharge diagnosis compared with functional neurological symptom disorder.

RESUMEN

INTRODUCTION: Research suggests that patients with Functional Neurological Symptom Disorder (pwFND) struggle to identify their own emotions and associated physiological cues (interoceptive sensitivity, IS). However, it is not known how this deficit interacts with stress. This study aimed to assess IS in pwFND at baseline and following stress induction, and relate the findings to self-reported emotion processing difficulties. METHODS: Twenty-six pwFND and 27 healthy controls performed the Heart Beat Detection Task pre- and post-stress induction with the Cold Pressor Test. Participants also completed questionnaires assessing anxiety (GAD-7) and depressive symptomology (PHQ-9), as well as emotion processing (EPS-25). RESULTS: Patients reported deficits in emotion processing (p < . 001) and had lower IS (p = .032) than healthy controls. IS improved following stress induction across both groups (p = .003) but patients' IS was lower than that of healthy controls' pre-and post-stress induction. Exploratory analyses revealed that patients reporting sensory symptoms had lower IS at baseline than patients who did not. CONCLUSION: Our findings suggest that pwFND are relatively impaired in the identification of their emotions at baseline and following stress induction. This may be related to the experience of functional sensory symptoms and has implications for the psychological treatment of emotion dysregulation in this population.

RESUMEN

Pediatric functional neurological symptom disorder (FNSD or conversion disorder) is an often misunderstood but treatable condition that frequently presents in medical settings with unexplained symptoms. Although research regarding treatment of pediatric FNSD is increasing, it is still in its infancy and studies in pediatrics do not provide clear guidelines about which patients are most likely to benefit from various treatments. The role of pediatric psychologists may include consultation, assessment, treatment, program development, and providing education to patients, families, and healthcare colleagues in various disciplines. The purpose of this article is to provide a review of FNSD, discuss the importance of timely and accurate diagnosis, suggest how to present information to patients and families, and present options for treatment that are either supported by preliminary research or clinical experiences of the authors.

RESUMEN

OBJECTIVES: Psychiatry training is lacking examples of neuroscience education that translates neuroscience literature into accessible clinically oriented concepts. The authors created a teaching activity using patient-centered neuroscience education that focused on delivering the diagnosis of functional neurological disorder (FND). This study aimed to (i) develop a workshop modeling a clinician-patient interaction, (ii) provide a modern neuroscience perspective of FND, and (iii) evaluate the change in clinicians' perceptions of FND. METHODS: A total of six workshops (each 1 h long and consisting of a video, PowerPoint slides, and pre and post questionnaires) were conducted. Paired t tests were used to measure the change. RESULTS: Forty-seven clinicians participated. After completing the workshop, nearly all endorsed that functional symptoms are "real" (95%) and that treatment is helpful (100%). Participants also reported a greater comfort level with discussing FND diagnosis (46% vs 85%, p < 0.001), an overall increase in understanding the disorder (33% vs 82%, p < 0.001), assessing need for tests (33% vs 66%, p < 0.001), understanding treatment options (26% vs 89%, p < 0.001), and recognition that treatment can help control these symptoms (81% vs 100%, p < 0.01). In addition, learners were more likely to report that patients with FND are truthful (75% vs 95%, p < 0.001) and less likely to be manipulative (48% vs 80%, p < 0.001). CONCLUSIONS: A brief, educational intervention using neuroscience-based content was found to significantly improve clinicians' perception and confidence when delivering the diagnosis of FND.

RESUMEN

OBJECTIVE: The authors evaluated potential predisposing vulnerabilities and perpetuating factors among individuals with functional neurological disorder (FND) by using the novel Lifespan Negative Experiences Scale (LiNES), which assesses retrospective self-report of interpersonal trauma, negative affect, and relationship insecurity at three developmental stages: childhood, adolescence, and adulthood. METHODS: The LiNES, Childhood Abuse and Trauma Scale (CATS), Relationship Scales Questionnaire (RSQ), and Positive and Negative Affect Schedule (PANAS) were administered to 71 individuals with FND. The reliability and validity of LiNES were examined by correlation with the other measures. FND patients' responses on LiNES were compared with those of 170 healthy control subjects. RESULTS: LiNES scores in the FND group were internally consistent and correlated highly with CATS, RSQ, and PANAS scores. At each developmental stage, LiNES trauma scores were higher among patients with FND, compared with control subjects. The FND subgroup, which comprised patients who also had nonepileptic attack disorder, had higher trauma scores, compared with the FND-only subgroup. Compared with control subjects, patients with FND reported greater negative affect and relationship insecurity in adulthood. Lifetime LiNES scores for interpersonal trauma and relationship insecurity predicted FND group classification with >80% accuracy. CONCLUSIONS: This study provides further support for the links between FND and trauma, negative affect, and insecure attachment. Recognition of these factors is likely to be important for treatment and stratification of important subpopulations in research. These findings provide new insights into the association between the timing of negative experiences and their effect, with LiNES emerging as a potentially useful measure for patients presenting with FND.

RESUMEN

OBJECTIVE: The aim was to provide preliminary feasibility, safety, and efficacy data for a personalized virtual reality-delivered mirror visual feedback (VR-MVF) and exposure therapy (VR-ET) intervention for functional neurological disorder (FND). METHODS: Midpoint results of a single-blind, randomized controlled pilot are presented. Fourteen adults were randomly assigned to eight weekly 30-minute VR sessions-seven in the treatment arm and seven in the control arm. The treatment arm consisted of an immersive avatar-embodied VR-MVF treatment, plus optional weekly VR-ET starting at session 4 if participants had identifiable FND triggers. The control arm received equally immersive nonembodied sessions involving exploration of a virtual interactive space. Feasibility was measured by acceptability of randomization, completion rates, side effects, adverse events, and integrity of blinding procedures. Exploratory primary and secondary outcome measures were weekly symptom frequency and the Oxford Handicap Scale, respectively. RESULTS: Two early dropouts occurred in the treatment arm, resulting in an 86% completion rate (N=12/14). No side effects or adverse events were reported. Blind assessment at study end indicated that two of the seven treatment arm and three of the seven control arm participants incorrectly guessed their assignment. Changes in mean symptom frequency and disability were reported, but data will not be statistically analyzed until study end. CONCLUSIONS: This study is the first to report on MVF and VR for treatment of FND. Results generated thus far support feasibility and justify continuation of the study and further investigation into the efficacy of VR interventions for FND.

RESUMEN

OBJECTIVE: In their 1973 BMJ paper 'Cryptogenic Drop Attacks', Stevens and Matthews described 40, mostly middle-aged, female patients with drop attacks of unknown cause. Although clinically common, there has been little on this topic since. We aimed to determine clinical features, comorbidity and outcome of patients with drop attacks. METHODS: We carried out a retrospective review of patients with cryptogenic drop attacks seen consecutively by one clinician (JS) between 2006 and 2016. Demographics, phenomenology, duration and frequency of attacks, attack description and comorbid diagnoses were recorded. Patients were followed up with a notes review. RESULTS: 83 patients with cryptogenic drop attacks were predominantly female (89%, n=79), mean age 44 years. The majority (93%, n=77) could not remember the fall itself and almost half (43%, n=36) experienced prodromal dissociative symptoms. Mechanical trips or syncope preceded drop attacks, historically, in 24% (n=20) of cases. Persistent fatigue (73%, n=61), chronic pain (40%, n=33), functional limb weakness (31%,n=26) and dissociative (non-epileptic) attacks 28% (n=23) were common, with the latter usually preceding or emerging from drop attacks. At follow-up (88%, mean 38 months), 28% (n=23) had resolution of their drop attacks. Predisposing (but non-causative) disease comorbidity was found at baseline (n=12) and follow-up (n=5). CONCLUSIONS: Cryptogenic drop attacks are associated with high frequency of comorbid functional somatic and functional neurological disorders. Patients commonly have prodromal dissociative symptoms and in some there was a clear relationship with prior or subsequent dissociative (non-epileptic) attacks. Some cryptogenic drop attacks may be best understood as phenomena on the spectrum of dissociative attacks.

RESUMEN

We conducted a prospective cohort study, examining long-term adherence with psychiatric treatment among patients with psychogenic nonepileptic seizures (PNES). Subjects diagnosed with documented PNES were scheduled for 4 psychiatric visits. Survival analysis was performed, and covariates were assessed for association with time to nonadherence using Cox proportional hazard regression analysis. One hundred twenty-three subjects were recruited and followed for up to 17 months. Eighty percent of subjects attended the first outpatient visit, 42% attended the second, 24% attended the third, and only 14% remained adherent through the fourth visit. Two covariates were associated with nonadherence: (1) a prior diagnosis of PNES (hazard ratio 1.57, P-value .046); (2) a lower score on the Brief Illness Perception Questionnaire (BIPQ), signifying lower concern about one's illness (hazard ratio 0.77 for every 10-point increment on the 80-point scale, P-value .008). Adherence with psychiatric treatment among patients with PNES is initially reasonably good but worsens rapidly over visits 2-4. Risk factors for nonadherence include a history of a prior diagnosis of PNES, and a lower level of concern about the illness as assessed by a lower score on the BIPQ.

RESUMEN

BACKGROUND: Conversion disorder (CD) is a largely enigmatic disorder, one that requires a thorough ruling-out process. Prior research suggests that metaphors and conceptualization are rooted in physical experience, and that we interpret our affective world through metaphors. Spatial metaphors (interaction of affect and vertical space) are a prominent example of the grounding of metaphors. This is a relatively unpaved direction of research of CD. OBJECTIVES: The present pilot study sought to explore this view by investigating the "healthy is up, sick is down" spatial metaphors (e.g., "fell ill" and "top shape") in patients with CD, examining the correlation between the processing of bodily-related words, CD, and vertical space. We hypothesized that patients with CD, who experience their bodies as ill, will demonstrate a downwards bias when processing bodily-related words; corresponding to the "healthy is up, sick is down" spatial metaphor. METHODS: A total of 8 female patients (ages M-38.13 SD-10.44) and 42 female controls (ages M-36.4 SD-14.57) performed a visual attention task. Participants were asked to identify a spatial probe at the top or the bottom of a screen, following either a bodily related (e.g., arm) or non-bodily related (e.g., clock) prime word. RESULTS: As predicted, when processing bodily-related words, patients with CD demonstrated a downwards attention bias. Moreover, the higher the patient's level of somatization, the faster the patient detected lower (vs upper) spatial targets. CONCLUSIONS: This study suggests that the changed health paradigm of patients with CD is grounded in sensorimotor perception. Further research could propose new diagnostic and treatment options for CD.

RESUMEN

PURPOSE OF REVIEW: This paper examines the overlap of conversion disorder with chronic pain conditions, describes ways to assess for conversion disorder, and provides an overview of evidence-based treatments for conversion disorder and chronic pain, with a focus on conversion symptoms. RECENT FINDINGS: Conversion disorder is a significant problem that warrants further study, given that there are not many well-established guidelines. Accurate and timely assessment should help move treatment in a more fruitful direction and avoid unnecessary medical interventions. Advances in neuroimaging may also help further our understanding of conversion disorder. Creating a supportive environment and a collaborative treatment relationship and improving understanding of conversion symptoms appear to help individuals diagnosed with conversion disorder engage in appropriate treatments. Novel uses of earlier treatments, such as hypnosis and psychodynamic approaches, could potentially be beneficial and require a more vigorous and systematic study. There are treatments that produce significant improvements in functioning and reduction of physical symptoms from conversion disorder even for very severe cases. Hypnotherapy, cognitive behavioral therapy, and inpatient multidisciplinary treatment with intensive physiotherapy for severe cases have the most evidence to support reduction of symptoms. Components of treatment for conversion disorder overlap with treatments for chronic pain and can be used together to produce therapeutic effects for both conditions. Treatment needs to be tailored for each individual's specific symptoms.

RESUMEN

Psychogenic non-epileptic seizures (PNES) are a common problem in paediatric neurology and psychiatry that can best be understood as atypical responses to threat. Threats activate the body for action by mediating increases in arousal, respiration, and motor readiness. In previous studies, a range of cardiac, endocrine, brain-based, attention-bias, and behavioral measures have been used to demonstrate increases in arousal, vigilance, and motor readiness in patients with PNES. The current study uses respiratory measures to assess both the motor readiness of the respiratory system and the respiratory regulation of CO2. Baseline respiratory rates during clinical assessment and arterial CO2 levels during the hyperventilation component of routine video electroencephalogram were documented in 60 children and adolescents referred for treatment of PNES and in 50 controls. Patients showed elevated baseline respiratory rates [t(78) = 3.34, p = .001], with 36/52 (69%) of patients [vs. 11/28 (39%) controls] falling above the 75th percentile (χ 2 = 6.7343; df = 1; p = .009). Twenty-eight (47%) of patients [vs. 4/50 (8%) controls] showed a skewed hyperventilation-challenge profile-baseline PCO2 <36 mmHg, a trough PCO2 ≤ 20 mmHg, or a final PCO2 <36 mmHg after 15 min of recovery-signaling difficulties with CO2 regulation (χ 2 = 19.77; df = 1; p < .001). Children and adolescents with PNES present in a state of readiness-for-action characterized by high arousal coupled with activation of the respiratory motor system, increases in ventilation, and a hyperventilation-challenge profile shifted downward from homeostatic range. Breathing interventions that target arousal, decrease respiratory rate, and normalize ventilation and arterial CO2 may help patients shift brain-body state and avert PNES episodes.

RESUMEN

Functional neurological symptom disorder commonly presents with symptoms and defects of sensory and motor functions. Therefore, it is often mistaken for a medical condition. It is well known that functional neurological symptom disorder more often caused by psychological factors. There are three main approaches namely analytical, cognitive and biological to manage conversion disorder. Any of such approaches can be applied through short-term treatment programs. In this case, study a 12-year-old boy with the diagnosed functional neurological symptom disorder (psychogenic myopia) was put under a cognitive-analytical treatment. The outcome of this treatment modality was proved successful.

RESUMEN

Functional neurological symptom disorder (FND), previously known as conversion disorder, is a condition identified by neurological symptoms that cannot be explained by neurological disease or other medical conditions. FND typically presents with speech disturbances, visual disturbances, paralysis, somatic symptoms like myalgia, and chronic fatigue. This case report describes a case of a 44-year-old female, who presented with dysmenorrhea and had undergone total abdominal hysterectomy with bilateral salpingectomy and manifested as head titubation which was a conversion reaction. On evaluation, it was revealed that the patient had chronic depression and pain. This case report highlights a rare presentation of FND.

RESUMEN

Functional neurological symptom disorder (FNSD) is a complex condition with multifactorial etiology in which psychological factors may play a significant role in some patients, and they are not universally present or necessary for the diagnosis. FNSD can occur in the absence of psychological distress and each patient's presentation should be evaluated individually, considering a wide range of potential contributing factors. This is the first report related to prevalence data from Rwanda. This report presents a case study of a 15-year-old female patient who presented hemibody weakness without a structural neurological explanation on the background of the direct exposure to parental conflict. she was ultimately diagnosed with an FNSD and responded effectively to five sessions of cognitive behavioral therapy. Additionally, follow-up appointments were conducted every 4 months over the course of 1 year. During this period, the patient successfully resumed her studies and demonstrated normal functioning in all essential areas of daily life. This is the first reported case in Rwanda among similar cases. Addressing these specific stressors played a crucial role in the patient's overall outcome, leading to improved quality of care and prevention of unnecessary medical costs and interventions.

RESUMEN

Conversion disorder-called functional neurological symptom disorder in the DSM-5-has roots that trace back to antiquity. The term conversion, originating from psychoanalysis, signifies the appearance of physical symptoms as an effort to resolve or convey unconscious and distressing intrapsychic conflicts- "converting" them from manifesting in the mind to manifesting in the body. Despite efforts made in elucidating the neurobiological etiologies of functional neurological symptom disorder, a psychodynamic lens remains indispensable in understanding the patient. This article presents two patients who developed functional neurological symptom disorder, one after a COVID-19 vaccination and one in the context of long COVID. A discussion follows on the intrapersonal, interpersonal, and systemic etiological factors that predispose, precipitate, and perpetuate COVID-related functional neurological symptom disorder. We elaborate on psychodynamic psychological processes and conflicts that may unfold between patients with COVID-related functional neurological symptom disorder and their health care providers. We also share suggestions on how a consultation-liaison psychiatry team may offer support to the primary treating team to facilitate a therapeutic space within which patients with COVID-related functional neurological symptom disorder may recover.
