What the literature leaves open

  • However, this mechanism does not account for all the effects described on bone health associated with ASMs. The effects of CBZ on bone health and the endocrine system are not well understood. Because there is insufficient evidence regarding the effect of CBZ on bone metabolism in our region, addressing this knowledge gap is particularly important.

  • Our findings reveal well-established hormonal and lipid pathways alongside emerging but underexplored genetic mechanisms, highlighting key knowledge gaps that warrant further investigation.

  • There is a need for safer and more effective treatment options for preterm neonates with seizures. The current treatment options have limitations and potential adverse effects. There is a lack of randomized controlled trials comparing the effectiveness of different treatment options for preterm neonates with seizures.

  • The electroclinical spectrum of ictal lingual phenomenology remains incompletely defined. There are only a few video-documented cases of lingual seizures. The symptomatogenic network underlying lingual seizures is more complex than a strictly somatotopic representation of the tongue within the primary motor cortex.

  • The influence of anti-seizure medications on hormone metabolism and function, particularly mechanisms involving the hypothalamic-pituitary axis, should be carefully considered. There is a need to evaluate the effects of levetiracetam on thyroid function and volume in pediatric epileptic patients.

    Influence of Long-Term Anti-Seizure Medications on Redox Parameters in Human Blood · 2024 · DOI

  • Little is known about the impact of anti-seizure medications on redox homeostasis. There is a need to investigate the effects of long-term anti-seizure medications on antioxidant enzymes in human blood.

    Influence of Long-Term Anti-Seizure Medications on Redox Parameters in Human Blood · 2024 · DOI

  • Although structured chart review and adverse reporting systems were used, events may still be underreported.

    Rapid administration of undiluted IV push valproic acid · 2026 · DOI

  • Limited reliable biomarkers for individualized prediction of valproic acid efficacy and hepatotoxicity. Substantial interindividual variability exists in therapeutic efficacy and hepatotoxicity during valproic acid treatment.

  • The odds of spontaneous miscarriage, spontaneous fetal loss, elective cesarean section, 5-minute APGAR score <7, and admission to the neonatal intensive care unit were significantly greater in ASM-exposed than in unexposed pregnancies in women with the same indications, but the possible confounding effect of between-group differences in disease severity could not be assessed.

    Risk of Adverse Pregnancy Outcomes Associated With Antiseizure Medications and Their Indications · 2025 · DOI

  • Participants were divided into four subgroups based on ASM exposure: Subgroup 1, first trimester (T1) exposure (first 12 weeks); Subgroup 2, exposure limited to the first 140 days; Subgroup 3, exposure only after day 141; Subgroup 4, continuous exposure.

    Fetal outcomes of antiseizure medication use during pregnancy: A nationwide retrospective cohort study · 2025 · DOI

  • We here demonstrate that exposure to ETI during pregnancy is associated with observable molecular changes in the brain lipidome, which are not likely limited to the inhibition of DEGS.

    Exposure of dams to Elexacaftor/ Tezacaftor/Ivacaftor during pregnancy and breastfeeding induces reversible alterations in newborn wild type CD-1 mice · 2025 · DOI
