Abstract
Background and Objectives To evaluate the standardized mortality ratio (SMR) of patients in the United States referred to a multidisciplinary clinic for treatment of functional seizures. Methods We identified patients who had or had not died based on automated retrospective review of electronic health records from a registry of patients referred to a single-center multidisciplinary functional seizures treatment clinic. We calculated an SMR by comparing the number of observed deaths with the expected number of deaths in an age-matched, sex-matched, and race-matched population within the same state, and year records were available. Results A total of 700 patients with functional seizures (mean age 37 years, 78% female) were followed up for 1,329 patient-years for a median of 15 months per patient (interquartile range 6-37 months). We observed 11 deaths, corresponding to a mortality rate of 8.2 per 1,000 patient-years and an SMR of 2.4 (95% confidence interval: 1.17-4.22). Five of 9 patients with identified circumstances around their death were in hospice care when they passed. None of the identified causes of death were related to seizures directly. Discussion These data provide further evidence of elevated mortality in functional seizures soon after diagnosis and referral to treatment. These data from the decentralized health care system of the United States build on the findings from other countries with large-scale health registries.

Abstract
Objective To study the outcome of patients with psychogenic non-epileptic seizures (PNES) after their diagnosis in the epilepsy monitoring unit (EMU). Methods Patients diagnosed in our EMU with definite PNES between January 2009 and May 2023 were contacted by phone, and those who agreed to participate were asked a set of predetermined questions. Comparative analyses were carried out on several variables before and after diagnosis: number of participants with daily PNES, number of visits to the emergency department, number of participants who consulted their general practitioner or a neurologist outside of a scheduled follow-up, number of participants who took antiseizure medications (ASMs) or psychotropic drugs, and employment status. Results Out of the 103 patients with a definite diagnosis of PNES, 61 patients (79% female) accepted to participate in our study. The median age at PNES onset was 35 years, and the median delay to diagnosis was 3 years. Almost two-thirds (62%) were receiving ASMs and 40% psychotropic drugs. The mean stay at the EMU was 5 days. PNES diagnosis was explained to almost all patients (97%) by the end of their EMU stay and was well-accepted by most (89%). When contacted, 46% of participants no longer had PNES; 32% mentioned that their PNES had ceased immediately upon communication of the diagnosis. The median follow-up duration was 51 months. Fewer patients had daily seizures after the diagnosis (18 vs. 38%; p < 0.0455). Similarly, the median number of emergency department visits was significantly lower (0 vs. 2; p < 0.001). Only 17 patients consulted their general practitioner (vs. 40, p < 0.001) and 20 a neurologist (vs. 55, p < 0.001) after a PNES attack outside of a scheduled follow-up. The use of ASMs was also significantly reduced from 70 to 33% (p < 0.01), with only one still taking an ASM for its antiseizure properties. Significantly more participants were working at last follow-up than at PNES diagnosis (49 vs. 25%; p < 0.001). Conclusion Our study revealed a relatively favorable long-term outcome of definite PNES diagnosed in the EMU that translated in significant reductions in PNES frequency, health care utilization and ASM use, as well as a significant increase in employment rate.

Prevalence of ictal injuries in functional (psychogenic nonepileptic) seizures: A systematic review and meta-analysis. Epilepsia 2023; 64:3082-3098. [PMID: 37597258 DOI: 10.1111/epi.17752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Revised: 08/15/2023] [Accepted: 08/16/2023] [Indexed: 08/21/2023]
Abstract
OBJECTIVE Ictal injuries have long been considered typical signs of epileptic seizures. However, studies have shown that patients with functional seizures (FS)-also named psychogenic nonepileptic seizures-can also present these signs, misleading physicians and delaying a correct diagnosis. This systematic review aimed to assess the prevalence of injuries from FS. METHODS A literature search was performed in PubMed, Embase, LILACS (Latin American and Caribbean Health Sciences Literature), Scopus, Web of Science, PsycINFO, Google Scholar, OpenGrey, and ProQuest. Observational studies were included. The risk of bias was assessed using the Joanna Briggs Institute (JBI) checklist for studies reporting prevalence data. RStudio was used for meta-analyses. Cumulative evidence was evaluated according to Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) criteria. RESULTS From the 2607 identified records, 41 studies were included in the qualitative synthesis, and 28 were included in meta-analyses. A meta-analysis of 13 studies, including 1673 individuals, resulted in an overall lifetime prevalence of injuries due to FS per person of 25% (95% confidence interval [CI] = 19%-32%, I2 = 88%). Considering a limited period (video-electroencephalographic [VEEG] monitoring days), a meta-analysis of 13 studies, including 848 individuals, resulted in an injury prevalence due to FS per person of .7% (95% CI = 0%-3%, I2 = 73%). Also, a meta-analysis of eight studies, including 1000 individuals, resulted in a prevalence of injuries per FS of .1% (95% CI = 0%-.98%, I2 = 49%). The certainty in cumulative evidence assessed by GRADE was rated "very low" for lifetime prevalence of injuries per person, "low" for prevalence per person during VEEG monitoring, and "moderate" for prevalence per number of FS. SIGNIFICANCE Overall pooled lifetime prevalence of injuries due to FS per person was 25%. In comparison, the prevalence of injuries per person during VEEG monitoring and per functional seizure was .7% and .1%, respectively. [Correction added on 07 October 2023, after first online publication: In the preceding sentence, 'consecutively' was corrected to 'respectively'.] The evidence of the occurrence of injuries due to FS breaks the paradigm that epileptic seizures can cause injuries but FS cannot.

Abstract
Background and Objectives Chronic health conditions are influenced by social determinants of health (SDH) including neighborhood-linked markers of affluence. We explored whether neighborhood socioeconomic factors differ in people with different types of clinical movement disorders (MDs). Methods We conducted a retrospective study of patients seen in MD clinics at our center in 2021. Patient data were linked to the US National Neighborhood Data Archive linked to US census tract data. We evaluated variations in neighborhood socioeconomic factors across 8 different categories of MDs. Results Compared with the neighborhoods of patients with Parkinson disease, neighborhoods of patients with cerebellar ataxias, functional movement disorders, and Huntington disease were characterized by higher proportions of people earning less than 15,000 US dollars/year, people receiving public assistance, and people with less than a high school diploma. Discussion Neighborhood-linked SDH vary among different MDs. These findings have implications for public health interventions aimed at improving the care of people affected by MDs.

Prospective multicenter cohort study of possible psychogenic nonepileptic seizure cases-Results at 1-year follow-up examinations. Epilepsia Open 2023; 8:134-145. [PMID: 36509699 PMCID: PMC9978061 DOI: 10.1002/epi4.12683] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Accepted: 11/30/2022] [Indexed: 12/15/2022] Open
Abstract
OBJECTIVE The primary purpose of this prospective multicenter study was to examine clinical and demographic feature differences according to the diagnostic level of psychogenic nonepileptic seizures (PNES) and then clarify whether prognosis may also differ accordingly. METHODS Two hundred forty-two consecutive patients strongly suspected of having PNES attacks were invited to participate, of whom 52 did not consent or contact was lost. At the 1-year follow-up examination, PNES diagnosis was reconsidered in nine patients. In 96 patients, the diagnostic level remained the same (P-group), with that in 43 considered to be clinically established (CE-group) and in 42 documented (D-group). The Qolie-10 and NDDI-E questionnaires were examined at both the study entry and the follow-up examination. RESULTS Multiple regression analysis of quality of life (QoL) score (n = 173; R2 = 0.374; F = 7.349; P < 0.001) revealed NDDI-E score (t = -6.402; P < 0.001), age of PNES onset (t = -3.026; P = 0.003), and ethnic minority status (t = 3.068; P = 0.003) as significant contributors. At entry, the P-group showed the lowest PNES attack frequency (P < 0.000), the lowest rate of antiseizure, antidepressant, and antipsychotic medication (P < 0.000; P = 0.031; P = 0.013, respectively), and the lowest proportion of psychosis (P = 0.046). At follow-up, PNES attack frequency (P < 0.000), number of admittances to emergency room (P < 0.000), and scores for QoL (P < 0.000) as well as depression (P = 0.004) were found to be significantly improved together with other collateral indicators, such as rate of antiseizure medication prescription (P = 0.001) and psychiatric symptoms (P = 0.03). Multiple regression analysis of a sample limited to patients with intellectual disability (ID) (n = 44; R2 = 0.366; F = 4.493; P = 0.002) revealed continued psychotherapy at follow-up (t = 2.610, P = 0.013) and successful reduction in antiseizure medication (t = 2.868; P = 0.007) as positively related with improved QoL. SIGNIFICANCE Clinical and the socio-psychological constellation of possible, clinically established, and documented PNES were found to differ greatly. Unexpectedly, significant effects of the continuous psychotherapeutic intervention were confirmed in PNES patients with ID.

Abstract
Aims Somatic complaints are a frequent cause for consultation in primary care. In a transcultural context, somatic complaints are typically associated with psychological distress. A recent review about somatic symptom disorders in adolescence showed some nosographic heterogeneity and outlined various etiological hypotheses (traumatic, environmental, or neurologic), separate from the cross-cultural considerations. Migrants' children encounter specific problems involving cultural mixing-issues of filiation (familial transmission) and affiliation (belonging to a group). This paper aims to provide a systematic review of somatization in transcultural contexts among teenagers and young adults, aged 13 to 24, over the past decade. Methods This review adheres to the quality criteria set forth by the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Two authors queried three English databases (Medline, PsycInfo, WebOfScience) about somatization in transcultural contexts (migrant or non-Western population) among teenagers (13-18), young adults (19-24), or both. The methodological process comprised articles selection, data extraction, and then the analysis of emerging themes. Setting selection criteria to limit the transcultural field was difficult. Results The study analyzed 68 articles. We present a descriptive analysis of the results, centered on three main themes. First, the literature highlights a nosographic muddle reflected in the combination of anxious and depressive symptoms together with the highly variable symptomatology. Second, discrimination issues were prevalent among the migrant population. Lastly, the literature review points out possibilities for improving a care pathway and reducing the diagnostic delay induced by migrants' hesitancy about Western care and the recurrent use of inappropriate diagnostic criteria. Conclusion This review discusses the links between the nosographic muddle described here and the diagnostic delays these patients experience and raises concerns about rigid diagnostic compartmentalization. The work of the psychiatrist Frantz Fanon is here useful to understand externalized symptoms resulting from physical and psychological confinement. Discrimination issues raise questions about the cultural counter-transference health professionals experience in dealing with young migrants. Defining healthcare professionals' representations about somatic complaints in a transcultural context might be a fruitful path to explore in future research.

Abstract
PURPOSE OF REVIEW Psychogenic nonepileptic seizures (PNES) are the most common Functional Neurological Disorder/Conversion Disorder subtype. Significant advances have been made related to diagnosis, neurobiology, and treatment. In this review, we summarize updates in diagnosis and management over the past 3 years. RECENT FINDINGS Although evidence is mixed for the treatment of PNES, psychotherapeutic modalities remain a powerful instrument to empower patients and reduce seizures. A multidisciplinary, holistic approach is beneficial. While seizure freedom in all patients may not be the achieved endpoint in this chronic, paroxysmal disorder, quality of life can be improved with treatment. Additional treatment modalities and further research are needed for patients who are refractory to current treatment. Evidence-based therapies exist for PNES, and recent findings represent an increased understanding of the clinical and neurophysiologic aspects of PNES.

A pilot study assessing the feasibility and acceptability of Project UPLIFT adapted for patients with psychogenic nonepileptic seizures. Epilepsy Behav 2022; 127:108525. [PMID: 34999503 DOI: 10.1016/j.yebeh.2021.108525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 12/19/2021] [Accepted: 12/19/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND People with psychogenic nonepileptic seizures (PNES) are at elevated risk of multiple psychiatric comorbidities. Current treatment gaps highlight the need for time-limited, distance-delivered interventions that can be cost-effectively delivered to patients with PNES. Project UPLIFT is a self-management program addressing mood problems in epilepsy that has not previously been adapted for PNES. The purpose of this study was to assess the feasibility and acceptability of UPLIFT for patients with PNES. METHODS Project UPLIFT was minimally adapted by a multidisciplinary research group at Dartmouth-Hitchcock Medical Center. Participants were recruited into a nonrandomized pilot study and were assessed at baseline, after completing the intervention, and at 1-month follow-up. RESULTS The intervention was adapted and delivered without additional modification. A total of eight participants enrolled in the trial, and six participated in the first session. All six participants who started UPLIFT completed the intervention, with a 98% attendance record across the eight sessions. At follow-up, 100% reported that UPLIFT provided useful tools for daily life. All participants continued using UPLIFT after completing the program, and 83% felt it helped with seizure management. Preliminary results provide proof-of-concept for future efficacy trials. CONCLUSION This study provides initial support for the feasibility and acceptability of Project UPLIFT, minimally adapted for patients with PNES. As a time-limited program that can be distance-delivered to groups of patients, UPLIFT may be well-suited for the healthcare environment brought on by the COVID-19 pandemic.

Baslet G, Ridlon R, Raynor G, Gonsalvez I, Dworetzky BA. Sustained improvement with mindfulness-based therapy for psychogenic nonepileptic seizures. Epilepsy Behav 2022; 126:108478. [PMID: 34922325 DOI: 10.1016/j.yebeh.2021.108478] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 11/26/2021] [Accepted: 11/27/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND We previously reported on the efficacy of a manualized 12-session mindfulness-based therapy (MBT) for psychogenic nonepileptic seizures (PNES). Completion of MBT provided improvements in weekly PNES frequency and self-rated intensity. OBJECTIVES In this study, we aimed to determine sustainability of improvement of seizure-related measures at 3- to 6-month follow-up after treatment completion. We also examined changes at treatment end and at follow-up on therapeutic targets of the MBT program. METHODS Patients with documented PNES were recruited from 2014 to 2018. Baseline measures were collected at time of diagnosis (T0) and at first follow-up post-diagnosis (T1). Outcomes are reported at MBT treatment completion (T3) and 3- to 6-month follow-up (T4). The Wilcoxon signed-rank test was used for pair-wise comparisons of PNES frequency; linear mixed models were used for other outcomes. RESULTS Fourteen of the 26 MBT completers (54%) attended follow-up (median 147.5 days between T3 and T4). PNES frequency, intensity, and number of days/week with PNES remained reduced at T4 (p < 0.01 for all; median frequency reduction 1.3/week from T1). Illness perception and feeling understood remained improved at T4 (p < 0.001 for both) as did worry about PNES (p < 0.05). Illness attribution (physical, mental or both) changed from T0 to T3 (p < 0.01), but not to T4. Psychological flexibility did not change over time. CONCLUSION Previously reported improvements in seizure-related measures with MBT at treatment conclusion were maintained at 3- to 6-month follow-up. There were sustained improvements in some underlying processes (illness perception, feeling understood, and symptom worry) over the course of treatment and at follow-up. Long-term benefits of MBT need to be established with randomized controlled trials.

Epilepsy Behav 2021; 116:107767.

Abstract
Dissociative seizures (also known as psychogenic nonepileptic seizures) are a common functional neurological disorder that can be difficult to distinguish from epileptic seizures. Patients with dissociative seizures provide diagnostic challenges, leading to delays in care, inappropriate care, and significant healthcare utilization and associated costs. The dissociative seizure likelihood score (DSLS) was developed by Kerr and colleagues at UCLA to distinguish between patients with epileptic seizures and dissociative seizures based on clinical and medication history as well as features of seizure semiology. We validated this calculator at the University of Colorado, which is a Level 4 National Association of Epilepsy Center. The DSLS accurately predicted the diagnosis in 81% of patients, despite local variability in the factors associated with epileptic versus dissociative seizures between the two populations. The DSLS can be a useful tool to assist with history taking and may have important utility for clinical decision making with these difficult to distinguish patient populations.

Abstract
PURPOSE To evaluate psychosocial long-term outcome in patients diagnosed with psychogenic nonepileptic seizures (PNES) and to predict outcome of PNES, economic status, and quality of life (QoL) at follow-up. METHODS Patients diagnosed with PNES in the video-EEG-monitoring unit at our Epilepsy center between 2002-2016 were contacted by phone 1-16 years after communicating the diagnosis. Patients underwent a structured interview asking for current PNES status, psychosocial situation (economic status, marital status, setting of living, driving), depression, and QoL. RESULTS Of 70 PNES patients without comorbid epilepsy (age: 41.1 ± 13.5 years; 74 % female, follow-up: 5.2 ± 4.2 years), 23 patients (33 %) reported to be free of PNES during the last 12 months. Patients with cessation of PNES were younger at PNES onset (p < .01) and diagnosis (p < .01) and had a higher education (p < .05). At follow-up, the proportion of economically active patients only increased in individuals with cessation of PNES (p < .001) while an increased number of patients with persisting PNES relied on governmental support (p < .001). Cessation of PNES was associated with better mood (p < .01) and QoL (p < .001). In multiple regression models, cessation of PNES was only predicted by younger age at onset, while good economic outcome was determined by younger age and good economic status at diagnosis and cessation of PNES at follow-up. Good QoL at follow-up was predicted by low depressive symptoms, freedom of PNES, and economic activity at follow-up. CONCLUSION Long-term outcome in patients with PNES remains to be poor and the majority of patients continue to have PNES. Cessation of PNES was associated with good economic outcome, mood, and QoL.

Abstract
BACKGROUND There is a scarcity of reports from limited-resources countries on functional neurological disorder (FND). We therefore carried out this descriptive study from Sudan to highlight the clinical characteristics of patients and the cultural, diagnostic, and management outcome. METHOD Of 1000 new referrals and patients seen at a central neuropsychiatric clinic in Khartoum, Sudan, 40 fulfilled the criteria for FND. Subjects were diagnosed by excluding organic illness and confirming psychological distress through neuropsychological assessment and clinical interview. Mood was measured using the Beck Depression Inventory (BDI) and Hospital Anxiety and Depression (HAD) scales. RESULTS Young unemployed women constituted 60% of our sample. Most subjects presented with psychogenic nonepileptic seizures (82.5%), speech abnormalities (47.5%), and limb paralysis or weakness was (35%). Associated mood disorder was found in 97.5% of all subjects. However, 95% of our sample showed a remarkable clinical response to combination therapy (antidepressants and psychotherapy). SIGNIFICANCE Patients with FND showed strong evidence of comorbid affective disorders in the form of depression and anxiety disorder. Most patients (95%) responded well to combination therapy with antidepressants and psychotherapy. Sociodemographic correlates of FND in Sudan prove to be consistent with features found in Western cultures, with only minor idiosyncratic characteristics due to local culture.

Natural history of patients with psychogenic nonepileptic seizures. Seizure 2019; 66:22-25. [PMID: 30772644 DOI: 10.1016/j.seizure.2019.02.006] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2019] [Revised: 02/08/2019] [Accepted: 02/10/2019] [Indexed: 10/27/2022] Open
Abstract
PURPOSE The purpose of this study was to investigate the long-term outcome of patients with psychogenic nonepileptic seizures (PNES), who never visited a psychologist and never received a proper therapy for their condition (due to lack of resources). We also aimed to investigate factors potentially associated with the outcome in these patients. METHODS We studied all patients with PNES, who were admitted to the epilepsy monitoring unit at the Shiraz Comprehensive Epilepsy Center, from 2008 until 2013. In a phone call interview to the patients in November and December 2018, we obtained the following information: seizure outcome, history of receiving any psychotherapy after confirming their diagnosis at referral, and finally, their current marital status, education, and employment status. RESULTS 69 patients had the inclusion criteria. Thirty-six patients (52%) were seizure-free during the past 12 months, but 33 (48%) still suffer from seizures. The only variable (at diagnosis), which was significantly associated with their outcome, was duration of their condition before they received a definite diagnosis. CONCLUSION More than half of the patients with untreated PNES may become free of seizures after they receive a definite diagnosis and with the passage of time. Longer duration of PNES before the patients received a definite diagnosis may affect their long-term outcome.
