Objective: Epilepsy is a common comorbidity of glioblastoma. Seizures may occur in various phases of the disease. We aimed to assess potential risk factors for seizures in accordance with the point in time at which they occurred. Methods: We retrospectively analyzed medical files of adult patients with de novo glioblastoma treated at our institution between January 2006 and January 2020. We categorized seizures as preoperative seizures (POS), early postoperative seizures (EPS; before initiation of radio[chemo]therapy [RCT]), seizures during radiotherapy (SDR; during or <30 days after RCT), and posttherapeutic seizures (PTS; ≥30 days after completion of RCT). We addressed associations between patients' characteristics and their seizures. Results: In the final cohort (N = 520), 292 patients experienced seizures. POS, EPS, SDR, and/or PTS occurred in 29.6% (154/520), 6.0% (31/520), 13.8% (70/509), and 36.1% (152/421) of patients, respectively. POS occurred more frequently in patients with higher Karnofsky Performance Scale scores (odds ratio [OR] = 3.27, p =.001) and tumor location in the temporal lobe (OR = 1.51, p =.034). None of the parameters we analyzed was related to the occurrence of EPS. SDR were independently associated with tumor location (parietal lobe, OR = 1.86, p =.027) and POS, but not EPS, and were independent of RCT. PTS were independently associated with tumor progression (OR = 2.32, p <.001) and with occurrence of SDR (OR = 3.36, p <.001), and negatively correlated with temporal lobe location (OR =.58, p <.014). In patients with tumors exclusively located in the temporal lobe, complete tumor resection was associated with a decreased risk of postoperative seizures. Significance: Seizures in glioblastoma patients have various, time‐dependent risk factors. Temporal lobe localization was a risk factor for preoperative seizures; surgery may have had a protective effect in these patients. RCT did not have dose‐dependent pro‐ or anticonvulsive effects. PTS were associated with tumor progression. [ABSTRACT FROM AUTHOR]

Objective: Discrimination against persons with epilepsy (PWEs) may persist. The aim of this study was to examine whether epilepsy is an obstacle to desired friendship. Methods: A factorial survey (vignettes), which is less biased by social desirability, was applied to PWEs, their relatives, and lay persons. The vignettes described a person who was varied by the dimensions of age (younger, same age, older), gender (male, female), disease (healthy, mild epilepsy, severe epilepsy [generalized tonic–clonic seizures], diabetes), origin (German, non‐German), contact (phone/internet, activities at home, activities outside), frequency of contacts (weekly, monthly), and distance (around the corner, 10 km away). Respondents rated their willingness to befriend the person on a 10‐point Likert scale. Multivariate regression determined the contribution of each dimension on the judgment. Results: Participants were 64 PWEs (age = 37.1 ± 14.0 years), 64 relatives of PWEs (age = 45.1 ± 13.6 years), and 98 controls without contact with PWEs (age = 24.4 ± 10.1 years). Controls were less interested in a friendship with a PWE with mild epilepsy (−3.4%) and even more avoided PWEs with severe epilepsy (−11.7%), whereas in PWEs with tonic–clonic seizures, a mild form of epilepsy was actually conducive to friendship (+7.0%). Controls preferred females (+5.0%) and disliked younger people (−12.3%) and contacts via the internet or telephone (−7.3%). PWEs were also less interested in younger people (−5.8%), and relatives of PWEs had a lower preference for friendships with longer distance (−2.3%). Significance: PWEs still suffer from a risk of social avoidance, and this becomes more evident with generalized motor seizures. [ABSTRACT FROM AUTHOR]

Objective: Because resources are limited in modern health care systems, the decision on the allocation of expensive drugs can be supported by a public consent. This study examines how various factors influence subjectively perceived "fair" pricing of antiseizure medication (ASM) among four groups including physicians, persons with epilepsy (PWEs), their relatives, and a control group. Methods: We conducted a factorial survey. Vignettes featured a fictional PWE receiving a fictional ASM. The characteristics of the fictional PWE, ASM, and epilepsy varied. Participants were asked to assess the subjectively appropriate annual cost of ASM treatment per year for each scenario. Results: Fifty‐seven PWEs (mean age (SD) 37.7 ± 12.3, 45.6% female), 44 relatives (age 48.4 ± 15.7, 51.1% female), 46 neurologists (age 37.1 ± 9.6, 65.2% female), and 47 persons in the control group (age 31.2 ± 11.2, 68.1% female) completed the questionnaire. The amount of money that respondents were willing to spend for ASM treatment was higher than currently needed in Germany and increased with disease severity among all groups. All groups except for PWEs accepted higher costs of a drug with better seizure control. Physicians and the control group, but not PWEs and their relatives, tended to do so also for minor or no side effects. Physicians reduced the costs for unemployed patients and the control group spent less money for older patients. Significance: ASM effectiveness appears to justify higher costs. However, the control group attributed less money to older PWEs and physicians allocated fewer drug costs to unemployed PWEs. [ABSTRACT FROM AUTHOR]

Summary: Objective: To examine the long‐term outcome of psychological status, personality, and health‐related quality of life (HRQoL) in patients with psychogenic nonepileptic seizures (PNES) and to define predictors of favorable outcome of cessation of PNES. Method: Patients diagnosed with PNES during video–electroencephalography (EEG) monitoring at the Erlangen Epilepsy Center were contacted 1‐16 years after communicating the diagnosis. Follow‐up information from each participant was obtained by interview (PNES outcome) and by self‐reported questionnaires of psychological symptoms (Beck Depression Inventory‐II, Symptom Checklist‐90‐Standard, Dissociative Symptoms questionnaire), personality traits (Freiburg Personality Inventory‐Revised), and HRQoL (36‐Item Short Form Health Survey). Results: Fifty‐two patients participated in the study (mean age ± standard deviation [SD] 40.5 ± 14.0 years; 75% female, follow‐up: 5.3 ± 4.2 years). Nineteen patients (37%) were free of PNES for the past 12 months. Patients with persisting PNES were older at disease onset (32.9 vs 22.3 years, P < 0.01) and diagnosis (40.5 vs 27.2 years, P < 0.001), and showed worse psychological functioning, lower extraversion and life satisfaction, and higher inhibitedness and worse HRQoL than PNES‐free patients. Patients with cessation of PNES were within the normal range in all dimensions. Cessation of PNES was best predicted by younger age at PNES onset and higher extraversion. Significance: Outcome of PNES is poor, psychopathology is high, and HRQoL is low in patients with persistent PNES but may normalize with PNES cessation. High introversion and older age at PNES onset are risk factors for persistent PNES. [ABSTRACT FROM AUTHOR]

Long-term epilepsy associated tumors (LEATs) are a frequent cause of drug-resistant partial epilepsy. A reliable tumor diagnosis has an important impact on therapeutic strategies and prognosis in patients with epilepsy, but often is difficult by magnetic resonance imaging (MRI) only. Herein we analyzed a large LEAT cohort investigated by fluoroethyl--tyrosine-positron emission tomography (FET-PET). Thirty-six patients with chronic partial epilepsy and a LEAT-suspect MRI lesion were analyzed by FET-PET using visual inspection and quantitative analysis of standard uptake values (SUV). PET results were correlated with clinical and histopathologic data. FET-PET study was positive in 22 of 36 analyzed lesions and in 14 of 22 histologically verified LEAT lesions. The precise World Health Organization (WHO) tumoral entity was not predicted by FET-PET. Notably, FET uptake correlated strikingly with age at epilepsy onset (p = 0.001). Further correlations were seen for age at surgery (p = 0.007) and gadolinium-contrast enhancement on MRI (p < 0.05). FET-PET is a helpful tool for LEAT diagnosis, particularly when MRI readings are ambiguous. FET uptake, which is likely mediated by the -amino acid transporter (LAT) family, might indicate a principally important biologic property of certain LEATs, since LAT molecules also are involved in cell growth regulation.

Glutamic acid decarboxylase (GAD) is the enzyme which catalyzes the production of gamma aminobutyric acid (GABA), the main inhibitory neurotransmitter in the central nervous system (CNS). There is increasing evidence that severe GAD autoimmunity may be associated with refractory epilepsy. Immunomodulation and GABAergic drugs have been suggested as treatment options. We report here for the first time on a patient with sudden onset of refractory status epilepticus in the presence of strong intrathecal anti-GAD antibody synthesis who was successfully treated with cyclophosphamide, and give an overview of available data on epilepsy associated with GAD autoimmunity.
