Psychogenic non-epileptic seizures (PNES) are noticeable changes in an individual’s consciousness or behaviour that share a similar appearance to epileptic seizures, with the key difference being that PNES are not accompanied by electrophysiological changes [1]. Although as many as 15 different names have been documented in describing this condition [2], PNES is the term that will be employed throughout this systematic review. Reuber [3] posits that these seizures are best understood through the lens of a biopsychosocial, etiologic model, whereby interacting predisposing, precipitating, perpetuating and triggering factors are seen to play a role in the subsequent presentation of PNES.
