Surgical management is challenging, as lesions are frequently deep-seated or bilateral, and seizure onset often involves networks extending beyond the heterotopic tissue itself, with the precise contribution of the nodules varying between patients. This systematic review synthesises all available evidence on neurosurgical and invasive interventions for childhood-onset PVNH-associated epilepsy, focusing on outcomes and prognostic factors. We conducted a PRISMA 2020-compliant systematic review searching PubMed/MEDLINE, Scopus, and Web of Science from inception to 13 December 2025. Eligible studies reported neurosurgical interventions in patients with MRI- or histopathology-confirmed PVNH whose epilepsy began before age 18, with outcomes reported using Engel or ILAE classification. Two reviewers independently screened and extracted data. Methodological quality was appraised using GRADE. Findings were synthesised narratively due to the inherent heterogeneity of the included studies. Thirty studies comprising 134 patients met our inclusion criteria. Excellent outcomes, defined as seizure freedom or auras only, were achieved in 50.7% (n = 68), with 76.9% (n = 103) experiencing meaningful benefit, defined as at least a 50% reduction in seizure frequency. Outcomes were better in unilateral than bilateral PVNH (75.9%vs 33.8%, p < 0.001) and with complete rather than incomplete nodule removal (72.9%vs 25.0%, p < 0.001). Permanent morbidity was 10.4% (n = 14), predominantly visual field deficits. Invasive EEG-guided approaches can achieve seizure freedom in around half of children with PVNH-related epilepsy, with outcomes strongly predicted by laterality. As with all subgroup comparisons in this review, reported p-values reflect effect size across pooled retrospective cohorts rather than formal hypothesis testing. Minimally invasive ablation appears effective and safe, while neuromodulation offers palliation where curative treatment is not feasible.

Preclinical data indicated CNB had a broad spectrum of antiseizure activity in rodent models of generalized and focal seizures.

The certainty of evidence was evaluated using the GRADE criteria.</div></div><div><h3>Results</h3><div>Fourteen studies comprising 4230 participants were included. Overall vaccination willingness was 51.7% (95% CI: 36.6–68.8%, I²=98%). Among unvaccinated individuals, 44.2% (95% CI: 26.6–61.8%, I²=95%) expressed willingness to be vaccinated. Well-controlled epilepsy was associated with higher vaccination rates (OR 1.91, 95% CI: 1.49–2.46, I²=0%). Conversely, frequent seizures (daily/weekly) were associated with lower vaccination likelihood (OR 0.52, 95% CI: 0.35–0.76, I²=0%). The primary reasons for vaccine hesitancy were fear of seizure worsening (23.8–88.5% across studies) and concerns about side effects (13.0–53.0%). Methodological quality was generally poor, with only one study rated as \"satisfactory\" using NOS criteria. GRADE assessment indicated very low certainty of evidence due to serious risk of bias, inconsistency, and imprecision.</div></div><div><h3>Conclusions</h3><div>COVID-19 vaccine hesitancy remains present in people with epilepsy, primarily driven by concerns about seizure exacerbation. Individuals with well-controlled epilepsy show higher vaccination acceptance. Healthcare providers should address specific concerns about seizure control while emphasizing vaccine safety data. High-quality prospective studies using validated instruments are recommended.</div></div>","PeriodicalId":49552,"journal":{"name":"Seizure-European Journal of Epilepsy","volume":"138 ","pages":"Pages 198-211"},"PeriodicalIF":2.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147799220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
