What the literature leaves open

  • The study had limited data on time-related outcomes and adverse events. The study had to deal with inadequate handling of censoring in the included studies.

    Levetiracetam versus valproate for new-onset or previously treated but inadequately controlled epilepsy in children: a systematic review and meta-analysis of randomized controlled trials · 2026 · DOI

  • One challenge is the inconsistent findings on the association between ABCC2 polymorphisms and antiseizure medication resistance. Another challenge is the lack of statistical power in many of the included studies. The study also faces the challenge of heterogeneity across studies, which is addressed using random-effects meta-analysis.

  • The study faced challenges in collecting data from adolescents with epilepsy, including the need for written informed consent from parents or legal guardians. The study had to exclude individuals with intellectual disability or communicative barriers that prevented the adolescent from accurately understanding and independently completing the quality of life questionnaire.

  • There is a scarcity of data on epilepsy genetics in Africa. More than two-third of African nations have not had a single publication in epilepsy genetics. The lack of widespread availability of molecular diagnosis capabilities is a significant challenge.

    Epilepsy genetics in Africa: a systematic review · 2026 · DOI

  • The lack of adequate instruments to evaluate the impact of Dravet syndrome on behavior is a significant challenge. The need to consider the level of intellectual disability frequently observed in individuals with Dravet syndrome adds to the complexity of assessing aggressive behavior.

    Assessment of aggressive behavior in Dravet syndrome: a critical look · 2024 · DOI

  • Altered network connectivity has emerged as a candidate biomarker of the epileptogenic zone, but how connectivity is altered in the epileptogenic zone remains uncertain, with prior studies reporting inconsistent results.

    Pathophysiology of sudden unexpected death in epilepsy: a devasting convergence of dysfunction in brain, respiratory systems, and heart · 2026 · DOI

  • While microglia are a predominant source of brain‐derived neurotrophic factor (BDNF) in the acute phase after brain injury, the role of microglial BDNF and its signaling in KCC2 dysregulation and early post‐stroke seizure susceptibility remain poorly defined.

    KCC2 Dysfunction Mediated by Microglial BDNF / TrkB Signaling Exacerbates Early Post‐Stroke Seizure Susceptibility · 2026 · DOI

  • While various animal models of mesial temporal lobe epilepsy (MTLE) exist, a validated model based solely on hippocampal GABAergic interneuron loss is lacking.

    Ablation of Unilateral Hippocampal GABAergic Neurons: A Novel Mouse Model of Mesial Temporal Lobe Epilepsy With Hippocampal Sclerosis · 2026 · DOI

  • Temporal lobe epilepsy (TLE) is characterized by synaptic dysfunction for which targeted therapies are lacking.

  • MCC-135 has shown potential as an antiseizure medication due to its ability to downregulate NCX and reduce intracellular calcium overload; however, its role and mechanism in epilepsy remain unclear.

    MCC ‐135 Exerts Antiepileptic and Neuroprotective Effects by Downregulating NCX1 Expression to Decrease Intracellular Calcium Overload in the Hippocampus · 2026 · DOI

  • Future research should focus on improving robustness and reproducibility to facilitate clinical translation.

    Clinical Utility of Z‐Score Distribution Mapping in Epileptogenic Zone Localizations · 2026 · DOI

  • However, whether these associations reflect causality and whether SUA provides incremental predictive value beyond established clinical factors remains unknown.
