- Epilepsy has well-documented associations with low income and low education levels, but the impact of a patient's socioeconomic standing (SES) on the effects of epilepsy have been less studied.We performed a register-based cross-sectional study and asked if SES was associated with more severe epilepsy or limited access to care in Sweden, where health care is universal, and if socioeconomic outcomes (employment and income) differed for persons with epilepsy (PWE) with different levels of educational attainment. The study cohort consisted of all adult patients with an epilepsy diagnosis in the Swedish patient register in 2000-2015 (n = 126,406) and controls (n = 379,131) matched for age, gender, and place of birth.Somatic and psychiatric comorbidities were more common in PWE, while education and income levels were lower. Among PWE, hospitalizations were more common in persons with lower income or education. Having at least one prescription written by a neurologist in the study period was more common in the high-income and high-education groups. Finally, although low educational attainment was associated with low levels of income and inversely associated with employment in both persons with epilepsy and controls, regression analyses demonstrated that these associations were much more noticeable in cases than controls.We conclude that both the severity and consequences of epilepsy are greater in persons of low SES, even in a country with universal health care. This indicates that universal access may not be sufficient to mitigate socioeconomic inequity in epilepsy.

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of this population-based, cross-sectional study was to describe caregiver-reported seizure precipitants, measures taken to prevent seizures and rescue therapies in children with Dravet Syndrome (DS). Methods: In a population-based study, caregivers of 42/48 Swedish children with DS born between 2000 and 2018 were interviewed. Frequency of precipitants, preventive measures, and rescue therapies were compared between children born 2000-2009 and 2010-2018 and between `severe acute accent and `less severe acute accent epilepsy.Results: All children had experienced precipitants. Preventive measures were employed in all. Seizures had been provoked by a median of seven (range 2-11) out of 13 factors. A median of eight (range 1-17) preventive measures out of 19 were reported. The most common precipitants were fever (n=42, 100%), and afebrile in-fections (n=39/42, 93%). Afebrile infections (p=0.014) and reduced ambient temperature (p=0.006) were more common precipitants in younger children, and bright light in children with severe epilepsy (p=0.013).The most common factors avoided were warm weather (n=35/42, 83%) and physical activity (n=27/42, 64%). It was more common to avoid strong emotions (p=0.035) and reduced temperature (p=0.002) in younger children, and to avoid infections (p=0.024) and crowds (p=0.046) in children with 'severe' epilepsy. Many children (n=28/42, 67%) or their siblings (n=16/34, 47% of individuals with siblings) had stayed home to avoid infections in school/day-care. Use of emergency medicines was more frequent in younger children (p=0.006) and in children with 'severe' epilepsy (p=0.007). Significance: Caregiver-reported seizure precipitants are common in DS. Caregivers employ a range of measures to avoid seizures, restricting family life.

- Purpose: This study estimated epilepsy prevalence, psychiatric co-morbidity and annual costs associated with epilepsy.Methods: We used Danish national health registers to identify persons diagnosed with epilepsy and psychiatric disorders, and persons using antiseizure medication and persons using drugs for psychiatric disorders. We calculated the prevalence of epilepsy and co-morbid psychiatric disorders in Denmark on December 31, 2016, using information on epilepsy and psychiatric disorders based on combinations of hospital contacts and use of antiseizure and psychoactive medication. Further, direct and indirect annual costs associated with epilepsy were calculated using individual-level data from a range of socioeconomic registers.Results: There were 5,044,367 persons alive and living in Denmark on December 31, 2016, including 33,628 persons with at least one hospital contact with epilepsy in the previous five years (epilepsy prevalence 0.67% (0.69% males; 0.65% females)). Among these persons with epilepsy, we identified 12,562 (37.4%) persons with a psychiatric disorder or use of drugs used for psychiatric disorders as compared with 801,052 (15.9%) persons in the general population. The estimated total annual individual net costs associated with epilepsy was €30,683. Compared with prevalence estimates on December 31, 2006, the prevalence of epilepsy on December 31, 2016, was slightly higher in the older population and slightly lower in childrenConclusions: Population estimates from national registers provide epilepsy prevalence estimates of approximately 0.6–0.7% - similar to previous reviews of epilepsy prevalence. In addition, the national sample allowed idenitfication of high prevalence of psychiatric disorders and high societal costs associated with epielspy.

Somatostatin receptor expression and mTOR pathway activation in glioneuronal tumours of childhood
- 2020
-
Ingår i: Seizure. - : Elsevier BV. - 1059-1311 .- 1532-2688. ; 76, s. 123-130

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To investigate the expression of somatostatin receptors (SSTRs) and markers of mTOR pathway in paediatric glioneuronal tumours and correlate these findings with tumour type, BRAFV600E mutational status and clinical characteristics such as tumour location, seizure frequency and duration, and age.Method: 37 children and adolescents with a neuropathological diagnosis of glioneuronal tumour were identified over a 22-year period. Immunohistochemical analyses for SSTRs type 1, 2A, 3, 5 and ezrin-radixin-moesin (ERM) and phosphorylated S6 (pS6), which are indicators of mTOR pathway activation, were performed in tumour specimens from 33 patients and evaluated using the immunoreactive score (IRS). The IRS were compared to tumour type, BRAFV600E status and clinical characteristics.Results: Ganglioglioma (GG) was the most frequently encountered subgroup (n = 27), followed by dysembryoplastic neuroepithelial tumour (DNET; n=4). GGs expressed SSTR2A and SSTR3 to a high extent, 56 % and 44 % respectively. Expression of SSTR2A was also found in DNETs. Signs of mTOR pathway activation were abundant in GGs, but only present in one DNET. No correlations with BRAFV600E presence or clinical characteristics were found.Conclusions: Expression of SSTRs and activation of mTOR pathway in paediatric glioneuronal tumour suggest that somatostatin analogues and mTOR inhibitors may have potential therapeutic implications in a subset of inoperable childhood glioneuronal tumours causing medically refractory epilepsy and/or tumour growth. Further clinical studies are warranted to validate these findings.

- 2021
-
Ingår i: Seizure-European Journal of Epilepsy. - : Elsevier BV. - 1059-1311. ; 92, s. 62-67

Tidskriftsartikel (refereegranskat)abstract
- Background: Biochemical markers of brain pathology could potentially contribute to diagnosis and prediction in epilepsy. We describe levels of five brain injury markers in adults with new-onset seizures, and assess group differences in patients with a single seizure, epilepsy, and poststroke epilepsy. Methods: In this prospective observational study, adults with new-onset seizures were recruited at Sahlgrenska University Hospital, Sweden, and concentrations of glial fibrillary acidic protein (GFAP), neurofilament light (NfL), microtubule-associated protein tau (tau), S100 calcium-binding protein (S100B), and neuron-specific enolase (NSE) were measured. Participants were categorized as epilepsy, poststroke epilepsy (PSE), or single seizure (no additional seizures). Patients were followed until a diagnosis of epilepsy or PSE, or for at least two years in single seizure cases. Results: The cohort included 23 (37%) individuals with a single seizure, 24 (39%) with epilepsy, and 15 (24%) with PSE. The concentrations of S100B were higher in patients with epilepsy and PSE than in single seizures (p = 0.0023 and p = 0.0162, respectively). The concentrations of NfL were higher in patients with PSE than in single seizures (p=0.0027). After age-normalization, levels of S100B were higher in patients with epilepsy and levels of NfL were higher in patients with PSE (p = 0.0021 and p = 0.0180). Conclusion: Levels of S100B and NfL were higher in patients with epilepsy or PSE than patients with single seizures. Further studies are needed to investigate the biomarker potential of brain injury markers as predictors of epilepsy course or indicators of epileptogenesis.

- The transfer from paediatric to adult care can be a complex process in children with epilepsy. Inadequate care during this phase can affect long-term medical and psychosocial outcomes. The aim of this study was to review studies on transitional care from paediatric to adult healthcare for young persons with epilepsy in order to synthesize evidence for best practice. We undertook a systematic review following PRISMA guidelines and employed narrative synthesis. A total of 36 articles were included, of which 11 were interventional studies and 25 observational studies. Study quality was rated as 'good' for only four studies. Interventions included joint or multidisciplinary clinics, education (patient and health professional education) and extended service provision (Saturday clinics, peer-groups). All studies observed a positive effect experienced by the participants, regardless of intervention type. Observational studies showed that transition plans/programmes are asked for but frequently not existing or not adapted to subgroups with intellectual disability or other neurodevelopmental conditions. The results of this systematic review on transitional care in epilepsy suggest that a planned transition process likely enhances medical and psychosocial outcomes for young people with epilepsy, but the body of evidence is limited and there are significant gaps in knowledge of what efficacious transition constitutes. More studies are needed employing qualitative and quantitative methods to further explore the needs of young people with epilepsy and their families but also robust study designs to investigate the impact of interventions on medical and psychosocial outcomes.

Risk of stroke after new-onset seizures
- 2020

- Purpose: Observational cohort studies have reported a potentially increased risk of stroke in patients with epileptic seizures. Whether late-onset seizures merit primary stroke prophylaxis is not known, and more information on stroke risk is needed for the planning of RCTs. We performed a case-control study based on Swedish national registers to quantify the risk of stroke after epileptic seizures. Methods: Cases <= 100 years of age with a first-ever stroke 2001-2009 were identified through the Swedish Stroke Register, and stroke-free controls (matched for age and sex) were obtained from the Population Register. The National Patient Register provided information on diagnostic codes for seizures, epilepsy and comorbidities. 123 105 stroke cases and 250 506 controls were included. Results: Epileptic seizures prior to index stroke date were detected in 1559 (1.27 %) cases and 1806 (0.72 %) controls, yielding an odds ratio (95 % confidence interval) for stroke of 1.77 (1.65-1.89). ORs were similar in men and women, but higher below the age of 75. An onset of seizures in the year preceding stroke date resulted in a higher risk for stroke (OR = 2.21, 95 % CI =1.79-2.72) compared to when more than 5 years had passed since the first seizure (OR = 1.57, 95 % CI = 1.43-1.72). Conclusion: A history of epileptic seizures was associated with an increased risk of subsequent stroke. The risk seems to be particularly high in the first year following seizure diagnosis, which supports the notion that unexplained late-onset seizures may merit swift assessment of vascular risk profile. The nature of stroke prevention requires further study.
