Abstract
The use of a suggestive seizure induction procedure (SSI) in medicine, particularly in the differential diagnosis of psychogenic nonepileptic epileptic seizures (PNES), is well documented. However, there is no description of standardized suggestion procedures used in children and adolescents. The research presents a standardized method of SSI with a cotton swab soaked in water. The protocol was developed based on of 544 placebo trials over ten years in a center for the differential diagnosis of children and adolescents. The protocol is a safe tool that allows inducing specific behavior in children and adolescents in whom there is a well-founded suspicion of PNES.

Abstract
PURPOSE The aim of the current study was to systematically review the literature on establishing epilepsy care centers in resource-limited nations in the world and to provide a comprehensive roadmap on this significantly needed endeavor. This work may provide guidance on how to develop an epilepsy care center in other resource-limited places in the world. METHODS Web of science, Science Direct, and MEDLINE (accessed from PubMed) from inception to March 2023 were systematically searched for relevant published manuscripts. In all electronic databases, the following search strategy was implemented and these key words were used (title/abstract): epilepsy AND resource. The inclusion criteria were all original studies and articles written in English. RESULTS We could identify nine manuscripts on how to successfully establish an epilepsy care center in resource-limited countries. Two models were identified for such an endeavor: developing a team of trained healthcare professionals (e.g., in Iran, India, China, Vietnam) or a twin affiliation between an advanced epilepsy surgery program in a developed country and a starting program in a developing country (e.g., in Georgia, Tunisia). CONCLUSION In order to successfully establish an epilepsy care center in resource-limited countries four pillars are needed: presence of skillful healthcare professionals, having access to basic investigative technologies (i.e., MRI and EEG), a careful planning, and raising awareness.

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
The dissociative disorders and germane conditions are reliably characterized by elevated responsiveness to direct verbal suggestions. However, it remains unclear whether atypical responsiveness to suggestion is similarly present in depersonalization-derealization disorder (DDD). 55 DDD patients and 36 healthy controls completed a standardised behavioural measure of direct verbal suggestibility that includes a correction for compliant responding (BSS-C), and psychometric measures of depersonalization-derealization (CDS), mindfulness (FFMQ), imagery vividness (VVIQ), and anxiety (GAD-7). Relative to controls, patients did not exhibit elevated suggestibility (g = 0.26, BF10 = .11) but displayed significantly lower mindfulness (g = 1.38), and imagery vividness (g = 0.63), and significantly greater anxiety (g = 1.39). Although suggestibility did not correlate with severity of depersonalization-derealization symptoms in controls, r = -.03 [95% CI: -.36, .30], there was a weak tendency for a positive association in patients, r = .25, [95% CI: -.03, .48]. Exploratory analyses revealed that patients with more severe anomalous bodily experiences were also more responsive to suggestion, an effect not seen in controls. This study demonstrates that DDD is not characterized by elevated responsiveness to direct verbal suggestions. These results have implications for the aetiology and treatment of this condition, as well as its classification as a dissociative disorder in psychiatric nosology.

Abstract
While the diagnosis and management of psychogenic non-epileptic seizures (PNES) remain challenging, certain evidence-based guidelines exist, which can help to optimize patient care. A multidisciplinary team approach appears to have many benefits. Current recommendations exist for some aspects of diagnosis and management of PNES, including levels of diagnostic certainty as proposed by the International League Against Epilepsy's expert Task Force on PNES. Other aspects of clinical still care lack clear consensus, including use of suggestion techniques for recording PNES and optimal terminology, since the term "functional seizures" has recently been proposed as a possible term to replace "PNES". The present article aims to (1) review current recommendations and (2) discuss our own team's experience in managing patients with PNES. This is organized chronologically in terms of the roles of the neurologist, psychiatrist and psychologist, and discusses diagnostic issues, psychiatric assessment and treatment, and psychotherapeutic approaches.

Use of suggestive seizure manipulation methods in the investigation of patients with possible psychogenic nonepileptic seizures-An international ILAE survey. Epilepsia Open 2021; 6:472-482. [PMID: 34288577 PMCID: PMC8408588 DOI: 10.1002/epi4.12521] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 06/25/2021] [Accepted: 06/27/2021] [Indexed: 02/05/2023] Open
Abstract
Video‐encephalographic (vEEG) seizure recordings make essential contributions to the differentiation of epilepsy and psychogenic nonepileptic seizures (PNES). The yield of vEEG examinations can be increased through suggestive seizure manipulation (SSM) (ie, activation/provocation/cessation procedures), but its use has raised ethical concerns. In preparation for guidelines on the investigation of patients with PNES, the ILAE PNES Task Force carried out an international survey to investigate practices of and opinions about SSM. An online questionnaire was developed by the ILAE PNES Task Force. Questions were asked at clinical unit or individual respondent level. All ILAE chapters were encouraged to send questionnaires to their members. The survey was open from July 1, 2019, to August 31, 2019. A total of 487 clinicians from 411 units across 94 countries responded. Some form of SSM was used in 296/411 units (72.0%). Over 90% reported the use of verbal suggestion, over 80% the use of activation procedures also capable of eliciting epileptic activity (hyperventilation or photic stimulation). Only 26.3% of units used techniques specifically intended to provoke PNES (eg, saline injection). Fewer than 10% of units had established protocols for SSM, only 20% of units required written patient consent, in 12.2% of units patients received explicitly false information to provoke seizures. Clinicians using SSM tended to perceive no ethical problems, whereas those not using SSM were likely to have ethical concerns about these methods. We conclude that the use of invasive nocebo techniques intended to provoke PNES in diagnostic settings has declined, but SSM is commonly combined with activation procedures also capable of eliciting epileptic activity. While research suggests that openness about the use of PNES‐specific nocebo techniques does not reduce diagnostic yield, very few units have suggestion protocols or seek patient consent. This could be addressed through establishing consensus guidance for the practice of SSM.
