The burden of disease of idiopathic/genetic generalized epilepsy - A nationwide online survey

Being an adolescent with epilepsy during the transition from pediatric to adult hospital care: A qualitative descriptive study

BACKGROUND

The transition from pediatric to adult care is challenging for adolescent patients despite numerous recommendations in recent decades. However, the perspective of the patients is sparsely investigated.

AIM

To explore the experiences and needs of adolescents with epilepsy (AWE) during the transition from pediatric to adult hospital care.

METHODS

We conducted 15 semi-structured interviews with AWEs aged 13-20 years and 10 h of field observations of consultations. Interviews were audio-recorded, transcribed, anonymized, and entered into NVivo (version 12, QSR International) with the transcribed field notes. Data were analyzed using systematic text condensation.

RESULTS

Three themes were identified: (1) Navigating epilepsy in everyday life; (2) The difficult balance between concealment and openness about epilepsy; and (3) Being seen as an individual and not an illness. AWEs' needs in transition are closely associated with their experiences and perceptions of illness, treatment, consultations, and seizures. Notably, AWEs reveal a significant concern about being overlooked beyond their medical condition in appointments.

CONCLUSIONS

This study highlights the vulnerability and challenges of AWEs transitioning to adult care. Overall, AWEs seek understanding, acceptance, and autonomy in managing their epilepsy and transitioning to adult care. Their experiences underscore the importance of holistic support and communication in healthcare settings. A concerted effort from healthcare professionals (HCP) is necessary to foster the recognition of AWEs as individuals with distinct personalities, needs, and capabilities.

Association of symptoms of psychiatric disease and electroencephalographic patterns in idiopathic generalized epilepsy

OBJECTIVE

Idiopathic generalized epilepsies (IGE) are genetic epilepsies with alterations of thalamo-frontocortical circuits that play a major role in seizure generation and propagation. Psychiatric diseases and drug resistance are strongly associated, but it remains unknown if they are symptoms of the same pathophysiological process. Hypothesizing that the same network alterations are associated with the frequency of epileptic discharges (ED) and psychiatric symptoms, we here tested the association of self-reported psychiatric symptoms and IGE severity estimated by electroencephalographic (EEG) biomarkers.

METHODS

Idiopathic generalized epilepsies patients were asked to fill out four validated psychiatric screening tools assessing symptoms of personality disorders (Standard Assessment of Personality- Abbreviated Scale), depression (Major Depression Inventory), impulsiveness (Barratt Impulsiveness Scale), and anxiety (brief Epilepsy Anxiety Survey Instrument). Blinded to results and clinical data on the patients, we analyzed the patients' EEGs, assessed, and quantified ED. The number and duration of ED divided by the duration of the EEG served as a proxy for the severity of IGE that was correlated with the results of the psychiatric screening.

RESULTS

Paired data from 64 patients were available for analysis. The duration of EDs per minute EEG was inversely associated with the time since the last seizure. The number of patients with generalized polyspike trains (n = 2), generalized paroxysmal fast activity (n = 3), and prolonged epileptiform discharges (n = 10) were too low for statistically meaningful analyses. Self-reported symptoms of depression, personality disorder, and impulsivity were not associated with EDs. In contrast, the duration of EDs per minute EEG was associated with self-reported symptoms of anxiety in univariate analyses, not significant, however, following adjustment for time since the last seizure in regression models.

SIGNIFICANCE

Self-reported symptoms of psychiatric diseases were not strongly associated with EDs as the best available quantifiable biomarker of IGE severity. As expected, the duration of EDs per minute and anxiety was inversely associated with time since the last seizure. Our data argue against a direct link between the frequency of EDs - as an objective proxy of IGE severity - and psychiatric symptoms.

Variation in prognosis and treatment outcome in juvenile myoclonic epilepsy: a Biology of Juvenile Myoclonic Epilepsy Consortium proposal for a practical definition and stratified medicine classifications

Reliable definitions, classifications and prognostic models are the cornerstones of stratified medicine, but none of the current classifications systems in epilepsy address prognostic or outcome issues. Although heterogeneity is widely acknowledged within epilepsy syndromes, the significance of variation in electroclinical features, comorbidities and treatment response, as they relate to diagnostic and prognostic purposes, has not been explored. In this paper, we aim to provide an evidence-based definition of juvenile myoclonic epilepsy showing that with a predefined and limited set of mandatory features, variation in juvenile myoclonic epilepsy phenotype can be exploited for prognostic purposes. Our study is based on clinical data collected by the Biology of Juvenile Myoclonic Epilepsy Consortium augmented by literature data. We review prognosis research on mortality and seizure remission, predictors of antiseizure medication resistance and selected adverse drug events to valproate, levetiracetam and lamotrigine. Based on our analysis, a simplified set of diagnostic criteria for juvenile myoclonic epilepsy includes the following: (i) myoclonic jerks as mandatory seizure type; (ii) a circadian timing for myoclonia not mandatory for the diagnosis of juvenile myoclonic epilepsy; (iii) age of onset ranging from 6 to 40 years; (iv) generalized EEG abnormalities; and (v) intelligence conforming to population distribution. We find sufficient evidence to propose a predictive model of antiseizure medication resistance that emphasises (i) absence seizures as the strongest stratifying factor with regard to antiseizure medication resistance or seizure freedom for both sexes and (ii) sex as a major stratifying factor, revealing elevated odds of antiseizure medication resistance that correlates to self-report of catamenial and stress-related factors including sleep deprivation. In women, there are reduced odds of antiseizure medication resistance associated with EEG-measured or self-reported photosensitivity. In conclusion, by applying a simplified set of criteria to define phenotypic variations of juvenile myoclonic epilepsy, our paper proposes an evidence-based definition and prognostic stratification of juvenile myoclonic epilepsy. Further studies in existing data sets of individual patient data would be helpful to replicate our findings, and prospective studies in inception cohorts will contribute to validate them in real-world practice for juvenile myoclonic epilepsy management.

Not always that EASI: Validating the Russian version of the epilepsy anxiety survey instrument and its brief counterpart

OBJECTIVE

To develop a Russian version of The Epilepsy Anxiety Survey Instrument (EASI) and assess its psychometric properties in a Russian sample of patients with epilepsy (PWE). To compare the brief version of EASI with the General Anxiety Disorder-7 (GAD-7) - the most common tool for a rapid anxiety screening.

METHODS

The study sample consisted of 181 consecutive Russian-speaking PWE. The Mini-International Neuropsychiatric Interview was used as a gold standard for diagnosing anxiety disorders. All patients completed the set of questionnaires - the Russian version of the GAD-7, The Neurological Disorders Depression Inventory for Epilepsy (NDDI-E), and the EASI. Internal reliability of the EASI and brEASI, convergent and divergent validity of the brEASI with the GAD-7 and the NDDI-E, and factor structure assessment were performed.

RESULTS

Among 33.7% of patients with epilepsy diagnosed with any anxiety disorder, 16% had panic disorder, 10.5% had agoraphobia, 8.3% had social anxiety disorder, 21.0% had generalized anxiety disorder, and 13.3% had several comorbid anxiety disorders. The EASI factor structure differed from the original, revealing an additional factor with two items. Nevertheless, the brief version (brEASI) showed excellent screening properties - the AUC to detect any anxiety disorder was 0.916 with the optimal cutoff point > 7 points.

CONCLUSION

The brEASI performed better than the GAD-7 in our sample and, therefore, may be considered a first-line screening tool for anxiety disorders in PWE.
