Objective: Typically diagnosed in early childhood or adolescence, TSC is a chronic, multisystemic disorder with age-dependent manifestations posing a challenge for transition and for specific surveillance throughout the lifetime. Data on the clinical features and severity of TSC in adults and on the prognosis of epilepsy are scarce. We analyzed the clinical and genetic features of a cohort of adult patients with TSC, to identify the prognostic predictors of seizure remission after a long follow-up., Method: We conducted a retrospective analysis of patients diagnosed with TSC according to the updated international diagnostic criteria. Pearson's chi-square or Fisher's exact test and Mann Whitney U test were used to compare variables among the Remission (R) and Non-Remission (NR) group. Univariate and multivariate logistic regression analyses were performed., Results: We selected 43 patients with TSC and neurological involvement in terms of epilepsy and/or brain lesions, attending the Epilepsy Center of our Institute: of them, 16 (37.2%) were transitioning from the pediatric care and 6 (13.9%) were referred by other specialists. Multiorgan involvement includes cutaneous (86.0%), nephrological (70.7%), hepatic (40.0%), ocular (34.3%), pneumological (28.6%) and cardiac (26.3%) manifestations. Thirty-nine patients (90.7 %) had epilepsy. The mean age at seizure onset was 4 ± 7.3 years: most patients (29, 76.3 %) presented with focal seizures or spasms by age 3 years; only 2 (5.3 %) had seizure onset in adulthood. Twenty-seven patients (69.2 %) experienced multiple seizure types overtime, 23 (59.0 %) had intellectual disability (ID). At last assessment, 14 (35.9 %) were seizure free (R group) and 25 (64.1 %) had drug-resistant seizures (NR group). At logistic regression univariate analysis, ID (OR 7.9, 95 % CI 1.8--34.7), multiple seizure types lifelong (OR 13.2, 95 % CI 2.6- 67.2), spasms/tonic seizures at presentation (OR 6.5, 95 % CI 1.2--35.2), a higher seizure frequency at onset (OR 5.4, 95 % CI 1.2--24.3), abnormal neurological examination (OR 9.8, 95 % CI 1.1--90.6) and pathogenic variants in TSC2 (OR 5.4, 95 % CI 1.2--24.5) were significantly associated with non-remission. In the multivariate analysis, both ID and multiple seizure types lifelong were confirmed as independent predictors of poor seizure outcome., Conclusions: In our cohort of adult patients with TSC, epilepsy remains one of the main neurological challenges with only 5.3% of cases manifesting in adulthood. Approximately 64% of these patients failed to achieve seizure remission. ID and multiple seizure types were the main predictors of poor outcome. Nephrological manifestations require continuous specific follow-up in adults., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Introduction: After the European Medicines Agency (EMA) warning on the use of valproate (VPA) in female patients, we explored the antiepileptic drug (AED) prescribing attitudes of Italian epileptologists with regard to sex and VPA use in patients with epilepsy., Material and Methods: A specifically designed 30-item questionnaire was distributed at the annual multicenter meeting of the Italian League Against Epilepsy (LICE), held in Rome on January 2018. One hundred and sixty-nine physicians answered the questionnaire., Results: In females, VPA was significantly less prescribed as first-choice AED in childhood absence epilepsy (22% females vs 64% males, p < 0.001), Dravet syndrome (54% vs 71%, p = 0.01), juvenile myoclonic epilepsy (JME) (2% vs 74%, p < 0.001), and undetermined epilepsy (0% vs 32%, p < 0.001). Ninety-six percent of the respondents inform teenage girls of the detrimental effects of intrauterine exposure to VPA; 74% recommend contraceptive measures when prescribing VPA. All the respondents stated that they were aware of the recommendations on VPA in female patients, and 64% claimed to have had difficulties in implementing them., Conclusions: The main challenges were represented by women with JME, who were seizure-free on VPA and failed to respond to levetiracetam and lamotrigine, and by little girls for whom VPA was considered the best choice. According to many Italian epileptologists, the decision to withdraw VPA should be shared with the patient., (Copyright © 2019 Elsevier Inc. All rights reserved.)

The beneficial effect of nicotine has been reported in autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) patients, but not tested in sporadic cases. Recently, a nicotine defect in the arousal pathway has been hypothesized even in sporadic NFLE patients and their relatives. This case-control family study was designed to test whether NFLE subjects were more likely to use tobacco than controls, as an indirect marker of cholinergic arousal system dysregulation. At least four relatives were included for each NFLE proband and control. Each subject was questioned about tobacco habits; 434 individuals were recruited. Moreover, we compared NFLE patients with age- and sex-matched controls to determine whether they are more likely to use tobacco. We found a slightly higher trend of tobacco use in NFLE probands compared to that in control subjects; we did not find any significant difference in the distribution of tobacco use among NFLE group compared to that in the control group., (Copyright © 2012 Elsevier Inc.

Psychogenic nonepileptic seizures (PNES) are highly prevalent in selected populations, with a strong impact in terms of morbidity and social cost. The gold standard for PNES diagnosis is video/EEG recording of a typical attack. However this technique is costly and not always available. In addition, many patients are treated with antiepileptic drugs for several years before undergoing video/EEG recording. The diagnosis is further complicated by concomitant epileptic seizures in some patients with PNES. Therefore, a good knowledge of PNES semiology is important for early screening of patients for video/EEG recording and for correct interpretation of the examination. We reviewed the literature on video/EEG studies reporting ictal PNES semiology to identify features indicative of psychogenic or epileptic seizures. Several features appeared to be useful in the clinical setting., (Copyright © 2011 Elsevier Inc. All rights reserved.)
