Epilepsy Overview - Concepedia

Principles

Definition

Epilepsy is a primary research domain in clinical neurology and fundamental neuroscience, focusing on the study of chronic brain disorders marked by recurrent, unprovoked seizures arising from aberrant neuronal excitability and network dysfunction. This field investigates the etiology, pathophysiology, diagnosis, and therapeutic interventions for these conditions, aiming to understand their underlying mechanisms and improve patient outcomes.

Key Figures

Electroclinical Localization era

Wilder Penfield [1] was a leading figure in the electroclinical localization era, with affiliations at McGill University [3] and Jefferson College [4]. Penfield [1] advanced the functional localization paradigm through his synthesis in EPILEPSY AND THE FUNCTIONAL ANATOMY OF THE HUMAN BRAIN [6], a landmark work that clarified how cortical maps of epileptic phenomena informed prognosis and surgical planning. David A. Prince [2] was affiliated with Stanford University [5] during this era. Prince [2] contributed to understanding inhibitory mechanisms in epileptic networks, notably in his 1968 paper Inhibition in “epileptic” neurons [7], which helped relate neuronal inhibition to localization patterns in epilepsy.

Limbic Circuit Epileptogenesis era

W. Allen Hauser[1] was a leading figure in epilepsy research during this era, with affiliations at Johns Hopkins University[3] and Albert Einstein College of Medicine[4]. His work on the epidemiology of epilepsy, as exemplified by The Epidemiology of Epilepsy in Rochester, Minnesota, 1935 Through 1967[7], provided essential baseline data on incidence and prevalence that guided public health planning in this era. Leonard T. Kurland[2] was another prominent figure in this era, with institutional ties to Icahn School of Medicine at Mount Sinai[5] and Columbia University[6]. As a co-author of The Epidemiology of Epilepsy in Rochester, Minnesota, 1935 Through 1967[7], Kurland contributed to shaping the era’s epidemiological perspective and resource planning, providing a foundation for subsequent translational and clinical work within limbic circuit epileptogenesis.

Precision Network Medicine era

Jerome Engel [1] is a leading figure in epilepsy research during the Precision Network Medicine era, with Harvard University [3] and Karolinska Institutet [4] as affiliated institutions. His contributions include advancing standardized terminology and organization of seizures and epilepsies, as reflected in the 2010 Revised terminology and concepts for organization of seizures and epilepsies [6], and in the 2005 Epileptic Seizures and Epilepsy: Definitions [7], both produced by ILAE/IBE bodies; he also codified knowledge in Epilepsy: A Comprehensive Textbook [8], consolidating a broad evidence base for clinicians and researchers in this era. Ingrid E. Scheffer [2] is a pivotal figure in precision network medicine in epilepsy, affiliated with Harvard University [3] and the University of California, San Francisco [5]. Ingrid E. Scheffer [2] contributed to precision network medicine in epilepsy by operationalizing seizure-type classification through the 2017 Operational classification of seizure types [9] and by linking genetic insights to clinical epilepsies demonstrated in the 1998 Febrile seizures and generalized epilepsy associated with a mutation in the Na+-channel ß1 subunit gene SCN1B [10], underscoring genotype-phenotype-informed approaches essential for personalized therapy.
