This paper redirects its focus from general brain mapping techniques to specifically investigate the impact of AI in the field of epilepsy diagnosis, concentrating exclusively on Electroencephalography (EEG) data. While earlier studies have predominantly centered on the automatic identification and prediction of seizures using EEG records, an emerging body of research delves into the potential of AI techniques to enhance the analysis of EEG data. This systematic review offers a comprehensive overview, commencing with a concise theoretical exposition on Artificial Neural Networks (ANNs) and attention mechanisms. Subsequent sections explore the applications of AI in EEG analysis for epilepsy, covering aspects such as diagnosis, lateralization, automated lesion detection, presurgical evaluation, and the prediction of postsurgical outcomes. The discussion not only highlights the promising aspects of AI in refining clinical practices but also underscores its potential in tailoring individualized treatments for epilepsy, considering it as a network disorder. The paper concludes by addressing limitations, challenges, and proposing future directions for the application of AI in epilepsy research. While acknowledging the transformative potential of this approach, it emphasizes the necessity for greater multicenter collaboration to amass high-quality data and ensure the open accessibility of developed codes and tools. Moreover, the application of AI models in Computer-Aided Diagnosis (CAD) has exhibited significant promise in enhancing the accuracy and efficiency of epilepsy and seizure diagnosis. This integration of advanced technologies contributes to the development of robust tools for clinical decision-making and underscores the potential for AI-driven solutions in neurological healthcare.</div></div>","PeriodicalId":11914,"journal":{"name":"Epilepsy Research","volume":"215 ","pages":"Article 107582"},"PeriodicalIF":2.0,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144089964","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}

To ensure data quality and minimize bias, we implemented standardized data collection procedures including: (1) systematic documentation using standardized seizure diaries, (2) regular follow-up assessments at predefined intervals, and (3) rigorous application of inclusion/exclusion criteria. Efficacy was assessed by seizure freedom rate, responder rate (≥50 % seizure reduction) and retention rate at 3, 6, 12 months and last follow-up. Safety was evaluated by monitoring adverse events. At last follow-up (mean 14 ± 4.95 months), the overall seizure freedom rate was 53.7 % and responder rate was 70.4 %. Idiopathic generalized epilepsy (IGE) patients showed better outcomes compared to non-IGE patients (seizure freedom: 63.6 % vs 10 %; responder rate: 79.5 % vs 30 %). PER demonstrated highest efficacy in generalized tonic-clonic seizures (80.4 % responder rate), followed by myoclonic (70.8 %) and absence seizures (50 %).

Despite their diversity, LMICs commonly experience a pronounced urban–rural disparity in epilepsy care, with rural communities facing limited healthcare infrastructure, a shortage of specialists, and pervasive stigma. Prevention efforts should focus on modifiable risk factors. Neurocysticercosis, a leading preventable cause of epilepsy in endemic regions, can be addressed through improved sanitation, access to clean water, and timely treatment supported by low-cost diagnostics. Enhancing perinatal care, injury prevention, and stroke management is also essential to reduce epilepsy incidence. Stigma continues to hinder care. Targeted education campaigns aimed at schools, community leaders, and the general public are vital to improving awareness and reducing discrimination. Bridging diagnostic gaps requires accessible, cost-effective tools such as portable EEGs, smartphone-based seizure recordings, and mobile diagnostic applications. Integration of these technologies into community health systems, and their use by trained primary care providers and community health workers, enables earlier detection and ongoing monitoring, particularly in underserved areas. Treatment strategies should prioritize “easy-to-use,” well-tolerated medications such as levetiracetam. Improving the affordability of antiseizure medications involves promoting generic alternatives, revising patent laws, regulating drug prices, setting price ceilings for essential medicines, and enabling bulk procurement. National health insurance schemes are crucial to ensure access for low-income populations. Expanding access through home-based care by community health workers, mobile outreach clinics, telemedicine, and collaboration with traditional healers can further improve treatment adherence and outcomes. Finally, training primary care physicians in epilepsy care is essential, as they are often the first point of contact for patients in rural and resource-limited settings.</div></div>","PeriodicalId":11914,"journal":{"name":"Epilepsy Research","volume":"215 ","pages":"Article 107586"},"PeriodicalIF":2.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143929431","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}
