Adherence to mental health care and caregiver-patient relationship after diagnosis of psychogenic non-epileptic seizures: Longitudinal follow-up study

International audiencePurpose: This study aimed to describe the quality of adherence to mental health care follow-up and the mental health caregiver-patient relationship after diagnosis of psychogenic non-epileptic seizures (PNES).Methods: We conducted an ancillary study of a multicenter prospective study. Patients (n = 108) received a standardized diagnostic explanation of PNES following video-EEG. They were referred to their community mental health centers or to a private psychiatrist/psychologist, who received written information about PNES and the study. Data collected about adherence to care (follow-up started or not, consensual and those who withdrew non-consensually, ongoing follow-up) were cross-tabulated from patients and care structures by telephone at 6, 12, 18 and 24 months after diagnosis. At M24, we collected reasons for stopping follow-up by phone using a predefined 9-item questionnaire. We also assessed the perception of the caregiver-patient relationship among patients who started follow-up and their mental health caregivers with a simple questionnaire based on five dimensions: feeling comfortable, continuity of care, content of therapy sessions, effectiveness of therapy sessions, and the patient's overall assessment of the follow-up.Results: From M6 to M24, ongoing follow-up decreased from 64.8 to 25.8%, while the "not following initial recommandations" group of patients (those who never started follow-up and those who withdrew non-consensually) increased from 35.2 to 64.9%. We found two main reasons for stopping follow-up: lack of interest and feeling better. Adherent patients had an overall more positive view of their therapy than caregivers.Conclusion: Only a third of PNES patients adhered to a mental health care program and felt comfortable in the caregiver-patient relationship. Solutions need to be found to help patients understand the interest of follow-up therapy and help mental health caregivers improve their feeling of competence

Post-traumatic factors are involved in the evolution of the number of seizures in patients with PNES

International audienceObjective: The purpose of this prospective study was to identify predictive factors of the evolution of the number of seizures.Methods: We included 85 individuals with a diagnosis of Psychogenic Nonepileptic Seizure (PNES) who completed at least two clinical interviews spaced by 6 months during a 24-month follow-up. Participants underwent a structured interview with an experimented clinician in PNES to complete standardized evaluation and validated scales. We collected sociodemographic and clinical data on PNES (number of seizures, duration of the disease), anxiety, depression, history of traumas, alexithymia, dissociation, and post-traumatic stress disorder (PTSD). We used a multivariate linear regression analysis to predict the characteristics independently associated with the evolution of the number of seizures in percentage.Results: Dissociation score was significantly associated with a negative evolution of the number of seizures (p < 0.002). Conversely, the diagnosis of PTSD at inclusion was correlated to a positive evolution of the number of seizures (p < 0.029).Conclusion: Dissociation was related to a more pejorative evolution of the number of seizures while PTSD diagnosis was associated with a decreased number of seizures. It is therefore essential to improve detection and treatment of post-traumatic dissociation. Further studies are required to understand the impact of PTSD on the evolution of the number of seizures

Explanatory factors of quality of life in psychogenic non-epileptic seizure

International audienceObjective: Previous studies showed that patients with Psychogenic Non-Epileptic Seizures (PNES) have poor quality of life (QoL). This study explored the explicative factors of the QoL at the time of diagnosis and monitored changes over the two years of follow-up.Methods: We evaluated 107 participants with a diagnosis of Psychogenic Non-Epileptic Seizure (PNES), every 6 months for 24 months. Quality of life (QoL) was evaluated using the QOLIE-31 and SF-36 scales (respectively specific and generic scales of QoL). Positive evolution of QoL was defined by the increase in the score of overall QoL using QOLIE-31 sub-scale from baseline to the last interview of the patient. We also collected for each patient data on psychiatric dimensions (childhood abuse, history of traumatic events, post-traumatic stress disorder (PTSD), depression, anxiety, alexithymia, and dissociation), clinical evolution of seizures and the number of mental health consultations.Results: According to the QOLIE-31 and the SF-36, depression (p ≤ 0.001), anxiety (p < 0.001), alexithymia (p ≤ 0.001), and dissociation (p ≤ 0.004) were related to QoL at the time of the diagnosis. According to SF-36 (mental and physical), PTSD was also significantly associated with QoL (p < 0.05). The number of seizures or the co-occurrence of epilepsy did not influence QoL. Positive evolution of QoL was linked to the number of consultations for mental health issues (p = 0.02).Significance: Post-traumatic dimensions (PTSD, dissociation), alexithymia and psychiatric comorbidities (depression and anxiety disorders) seem to alter QoL in people with PNES. The current study suggests that mental health care improves QoL of patients with PNES

Coffee consumption and seizure frequency in patients with drug-resistant focal epilepsy

International audienceThe outbreak of the SARS-CoV-2 virus, enhanced by rapid spreads of variants, has caused a major international health crisis, with serious public health and economic consequences. An agent-based model was designed to simulate the evolution of the epidemic in France over 2021 and the first six months of 2022. The study compares the efficiencies of four theoretical vaccination campaigns (over 6, 9, 12, and 18 months), combined with various non-pharmaceutical interventions. In France, with the emergence of the Alpha variant, without vaccination and despite strict barrier measures, more than 600,000 deaths would be observed. An efficient vaccination campaign (i.e., total coverage of the French population) over six months would divide the death toll by 10. A vaccination campaign of 12, instead of 6, months would slightly increase the disease-related mortality (+6%) but require a 77% increase in ICU bed–days. A campaign over 18 months would increase the disease-related mortality by 17% and require a 244% increase in ICU bed–days. Thus, it seems mandatory to vaccinate the highest possible percentage of the population within 12, or better yet, 9 months. The race against the epidemic and virus variants is really a matter of vaccination strategy

Glial Fibrillary Acidic Protein Autoimmunity A French Cohort Study

International audienceBackground and Objectives To report the clinical, biological, and imaging features and clinical course of a French cohort of patients with glial fibrillary acidic protein (GFAP) autoantibodies. Methods We retrospectively included all patients who tested positive for GFAP antibodies in the CSF by immunohistochemistry and confirmed by cell-based assay using cells expressing human GFAP alpha since 2017 from 2 French referral centers. Results We identified 46 patients with GFAP antibodies. Median age at onset was 43 years, and 65% were men. Infectious prodromal symptoms were found in 82%. Other autoimmune diseases were found in 22% of patients, and coexisting neural autoantibodies in 11%. Tumors were present in 24%, and T-cell dysfunction in 23%. The most frequent presentation was subacute meningoencephalitis (85%), with cerebellar dysfunction in 57% of cases. Other clinical presentations included myelitis (30%) and visual (35%) and peripheral nervous system involvement (24%). MRI showed perivascular radial enhancement in 32%, periventricular T2 hyperintensity in 41%, brainstem involvement in 31%, leptomeningeal enhancement in 26%, and reversible splenial lesions in 4 cases. A total of 33 of 40 patients had a monophasic course, associated with a good outcome at last follow-up (Rankin Score <= 2: 89%), despite a severe clinical presentation. Adult and pediatric features are similar. Thirty-two patients were treated with immunotherapy. A total of 11/22 patients showed negative conversion of GFAP antibodies. Discussion GFAP autoimmunity is mainly associated with acute/subacute meningoencephalomyelitis with prodromal symptoms, for which tumors and T-cell dysfunction are frequent triggers. The majority of patients followed a monophasic course with a good outcome
