Surgical intervention aims to remove the seizure onset zone (SOZ). This retrospective study investigated the relationship of SOZ size, ictal pattern, and extent of resection with surgical outcomes. TSC patients undergoing resective/ablative surgery with &gt;1-year follow-up and adequate imaging were included. Preoperative iEEG data were reviewed to determine ictal pattern and SOZ location. For outcomes, an ILAE score of 1–3 was defined as good and 4–6 as poor. Forty-four patients were included (age 117.4 ± 110.8 months). Of these, 59.1 % achieved a good outcome, while 40.9 % had a poor outcome. Size of SOZ was a significant factor (p = 0.009), with the poor outcome group having a larger SOZ (11.9 ± 6.7 electrode contacts) than the good outcome group (7.3 ± 7.2). SOZ number was significant (p = 0.020); &gt;1 SOZ was associated with poor outcome. These results demonstrate extent of SOZ as a predictor of seizure freedom following epilepsy surgery in a mostly pediatric TSC cohort. We hypothesize that these features represent biomarkers of focality of the epileptogenic zone and can be used to sharpen prognosis for epilepsy surgery outcomes in this cohort.</p></div>","PeriodicalId":11914,"journal":{"name":"Epilepsy Research","volume":"205 ","pages":"Article 107422"},"PeriodicalIF":2.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141912295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to assess the frequency of perceived stigma and factors associated with it among PWE in tertiary care centre.</p></div><div><h3>Material and methods</h3><p>A hospital-based, cross-sectional study was conducted using the Kilifi Stigma Scale of Epilepsy (KSSE) to assess the stigma associated with epilepsy and factors related to stigma.</p></div><div><h3>Results</h3><p>A total of 260 consecutive PWE were recruited, with a mean age of 28.12±9.96 years. The majority of subjects had primarily or secondarily generalized seizures (85 %), and most of PWE don’t know the cause of epilepsy (79.2 %) and feel that epilepsy is a contagious disease. Those with contagious beliefs felt more stigma (27.7 %). Stigma was perceived by 28.5 % of subjects using KSSE. Stigma was more perceived in those who had primarily or secondarily generalized seizures (23.9 %) and longer durations of anti-seizure medication (ASM) (24.4 %). Injury during a seizure was reported in 30 % of subjects and were more stigmatized (p&lt;.01).</p></div><div><h3>Conclusion</h3><p>Perceived stigma in PWE was found to be correlated with contagious beliefs. There is a need for awareness and educational programs by healthcare professionals at different levels to support and encourage positive beliefs, dispel myths about epilepsy, and inform PWEs of the fact that it is not a contagious disease.</p></div>","PeriodicalId":11914,"journal":{"name":"Epilepsy Research","volume":"205 ","pages":"Article 107428"},"PeriodicalIF":2.0,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141906259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
