Developmental and Epileptic Encephalopathies: Progress in Understanding and Clinical Implications

Abstract Developmental and epileptic encephalopathies (DEEs) are a group of complex pediatric epilepsies associated with adverse neurodevelopmental outcomes and multiaxial neurological morbidities. The understanding of DEE has evolved from its initial genetic underpinnings, to a clinically driven term encompassing a broader group of etiologies. Although individually rare, the DEEs constitute a sizeable group of pediatric epilepsies. It is especially important to recognize treatable or modifiable entities in this group. This review attempts to highlight the progress in understanding, along with the evolution of the conceptual framework of DEEs. A summary of the currently well-established DEE syndromes is provided along with available precision therapies, which might help the treating physician in the appropriate evaluation and management of the affected children.
