Abstract

Neuroimaging studies are essential in patients with epilepsy, both for diagnosis and surgical management. This article focuses on adult epileptic patients, reviewing the updated clinical criteria published by the International League Against Epilepsy for the definitions of seizures, epilepsy, and status epilepticus. It also describes the different types of epilepsy, the different presentations, the signs, the radiologic approach to managing seizures, and the differences between generalized and focal seizures. Finally, it discusses the relations between possible functional cerebral deficits secondary to potentially epileptogenic lesions and epilepsy surgery, underlining the importance of functional magnetic resonance imaging studies.

Resumen

Los estudios de neuroimagen son esenciales en los pacientes epilépticos, tanto para su diagnóstico como para el manejo quirúrgico. Este artículo se centra en el paciente epiléptico adulto y repasa los criterios clínicos actualizados según la ILAE (International League Against Epilepsy) para las definiciones de crisis comicial, epilepsia y estatus epiléptico. Además, se describen los distintos tipos de epilepsia, las diferentes presentaciones, la semiología, el enfoque radiológico para el manejo de las crisis epilépticas y las distinciones entre epilepsia generalizada y focal. Finalmente, se describen las relaciones de los posibles déficits funcionales cerebrales secundarios a las lesiones potencialmente epileptógenas y a la cirugía de la epilepsia, remarcando la relevancia de los estudios de resonancia magnética funcional.
