The classification of neuropsychiatric disorders in epilepsy: a proposal by the ILAE Commission on Psychobiology of Epilepsy

Epilepsy Behav. 2007 May;10(3):349-53. doi: 10.1016/j.yebeh.2006.10.002. Epub 2007 Mar 6.


The classification of psychiatric disorders in epilepsy has evolved considerably from the first attempts in the 19th century. A dedicated subcommission of the ILAE Commission on Psychobiology of Epilepsy (now the Commission on Neuropsychiatric Aspects) has developed this classification proposal. The aim of this proposal is to separate disorders comorbid with epilepsy and those that reflect ongoing epileptiform activity from epilepsy-specific disorders, and to attempt to subclassify the epilepsy-specific disorders alone. Further, the classification of epilepsy-specific psychiatric disorders has largely followed their relationship to the ictus, with factors such as relationship to antiepileptic drug (AED) change being coded as additional information. Finally, this proposal presents a clinical and descriptive system of classification rather than an etiological classification on the grounds that there is currently inadequate information for the latter approach to be employed globally.
