Review Meta Analysis
Identification of new epilepsy treatments: issues in preclinical methodology.
Preclinical research has facilitated the discovery of valuable drugs for the symptomatic treatment of epilepsy. Yet, despite these therapies, seizures are not adequately controlled in a third of all affected individuals, and comorbidities still impose a major burden on quality of life. The introduction of multiple new therapies into clinical use over the past two decades has done little to change this. ⋯ New therapies also need to address the special needs of certain subpopulations, that is, age- or gender-specific treatments. Preclinical development in these treatment areas is complex due to heterogeneity in presentation and etiology, and may need to be formulated with a specific seizure, epilepsy syndrome, or comorbidity in mind. The aim of this report is to provide a framework that will help define future guidelines that improve and standardize the design, reporting, and validation of data across preclinical antiepilepsy therapy development studies targeting drug-resistant seizures, epileptogenesis, and comorbidities.

This critical review refers to the new report on terminology and concepts for the organization of epilepsies by the Commission of the International League Against Epilepsy (ILAE). It is unfortunate that most of the proposals in the Commission's report are modified interpretations and nomenclature of previous ILAE classifications; new terms are not better than the old ones, and recent advances have not been incorporated. Hence, the new ILAE report met with considerable dissatisfaction from several expert epileptologists. ⋯ The ILAE should commission consensus of opinion from experts in specific fields in order to define each syndrome. Areas of certainties and uncertainties and of agreements and disagreements should be identified and explained. This approach may be the only way toward achieving a scientifically sound and clinically meaningful organizational system for the epileptic seizures and the epilepsies-a process that would incorporate the tremendous advances in our field and would be accepted by the wider community of clinicians and scientists.
