Factors associated with illness representations in adults with epileptic and functional seizures: a systematic review

Epilepsy and Functional Neurological Disorder (FND)1 and are two causes of seizures. Epilepsy refers to a neurological disorder characterised by recurrent episodes of paroxysmal brain dysfunction due to sudden, abnormal neuronal discharge (epileptiform activity) [1]. Functional seizures are the seizure variant of FND, resembling epileptic seizures but thought to represent episodes of dissociation [2]. Both seizure disorders are common; epilepsy has an estimated international lifetime prevalence of 7.6 per 1000 people [3].
